2019-05-07  James Youngman  <jay@gnu.org>

	Prepare to release CSSC version 1.4.1.
	* configure.ac: Set the version to 1.4.1.
	* NEWS: Fill in the release date of CSSC-1.4.1.

	Ignore some generated files.
	* auxfiles/.gitignore: Ignore CSSC.spec.

	Ignore some generated files in git.
	* .gitignore: Ignore config.h config.log maint.mk config.cache

	Fix some formatting issues (spurious commas for example) in copyright headers.  Run "make update-copyright" on the files.  Fix a syntax error introduced by that.

	Ensure that "make update-copyright" can update copyright years.
	* src/*.cc: Reducde indentation of copyright comment.  This should ensure
	that "make update-copyright" updates these files.
	* src/*.h: Likewise.

	Update copyright years.
	* src/*.cc: Update copyright years.
	* src/*.h: Update copyright years.
	* README-hacking,  auxfiles/check-testfiles.sh,  bootstrap,
	bootstrap.conf, docs/cssc.texi,  docs/gpl-3.0.texi,
	gl/Makefile.am, src/sccs.c,  src/sccsdiff.sh.in,
	testutils/ekko.c: Likewise.

	Checked out googletest 3f5b5b8f8493a03fa25f1e4a7eae7678514a431d

2019-05-07  Martin Wilck  <mwilck@suse.com>

	Checked out googletest release-1.8.1

2019-05-07  James Youngman  <jay@gnu.org>

	Get googletest from a git submodule.
	* unit-tests/get-gtest.sh (usage): Delete (we now use a git
	submodule instead).
	* README-hacking: Suggest deleting any old svn-based googletest
	directory before running bootstrap.

2019-05-07  Martin Wilck  <mwilck@suse.com>

	get-gtest.sh: googletest moved to git repo
	googletest isn't maintained in svn any more.

	unit tests: fix non-void functions returning void
	This causes compiler warnings which are considered fatal
	by rpmlint.

	testutils/yes: don't ignore SIGPIPE
	In rpm build environments, the inherited signal settings may be
	such that SIGPIPE is ignored. That would cause the "yes" tool
	to never terminate.

	sccs.1: fix undefined macro
	".om" is not defined in groff. I haven't found it anywhere in the
	docs.I believe this is a typo.

2019-05-07  James Youngman  <jay@gnu.org>

	Generate ChangeLog dynamically instead of maintaining it by hand.
	* ChangeLog: rename to ChangeLog.3, as ChangeLog itself will now
	be a dynamically-generated file.
	* bootstrap.conf: Create a dummy ChangeLog file if it does not
	already exist, to keep Automake happy.
	* (maintainer_modules): Add new section for modules mainly
	useful to maintainers, notably the gitlog-to-changelog module.
	* Makefile.am (gen-ChangeLog): Add rule for dynamically generating
	a ChangeLog file from git log entries.  Call it from dist-hook.
	* (EXTRA_DIST): Distribute ChangeLog.3
	* .gitignore: add ChangeLog.
	* configure.ac: Set AUXDIR in the Makefile so that ChangeLog
	generation knows where to find the script that does the work.
	* build-aux/gen-changelog.sh (top_srcdir): Add script for
	generating the ChangeLog file; adapted from the GNU findutils
	sources.

2019-05-06  James Youngman  <jay@gnu.org>

	Fix more compiler warnings.
	* src/what.cc: Forward-declare usage().
	* src/sccsfile.h: Declare print_flag2() functions.
	* src/get.cc (main): Format the (unsigned in) line count with %u
	instead of %d.
	* src/environment.cc (max_sfile_line_len): Simplify a complex
	boolean expression to silence a compiler warning suggesting
	parentheses.
	* src/writesubst.cc (write_subst): Print the output line number
	with %u since it is an unsigned int.
	* src/sf-write.cc (write_delta): Remove unsed variables "len" and
	"i".
	(write): Likewise, also "s".

	Fix some compiler warnings. Also turn off warning options which themselves just generate warnings.
	* src/run.cc (run): Avoid mixing signed/unsigned quantities.
	* src/sf-get2.cc (get): Avoid variable 'd' shadowing a variable of
	the same name in an outer scope.
	* src/sccsfile.h: Declare print_flag().
	* src/cap.cc (cap_min): Simplify this function; we only use it for
	trivially copyable types anyway.
	* configure.ac: Disable some warnings known to the manywarnings
	module (thus enabled with --enable-warnings) but which aren't
	suitable for C++ compilation.  We disable them so that we don't
	get a warning message from GCC about the inappropriate warning
	option.

	Merge branch 'master' of ssh://git.sv.gnu.org/srv/git/cssc

	Use block I/O for encoded streams.
	* src/encoding.cc (encode_line): return the number of bytes
	output.
	(encode_stream): Use the count returned by encode_line to perform
	block I/O (with fwrite) instead of string I/O (with fprintf).

1997-12-26  James Youngman  <jay@gnu.org>

	* testutils/realpwd.cc: Minor corrections to a comment.

	* testutils/Makefile.am: Added "user.c" which compiles to "user",
	a utility somewhat similar to "id".

	* tests/admin/users.sh: Added a couple of extra test cases wich
	run prs to make sure that the list of authorised users is
	correctly understood.

	* tests/Makefile.am: Added "large"; another subdirectory
	containing test suites.

	* split.cc: Commented everything out with #if 0; the split()
	function is now a member function of cssc_linebuf.

	* sf-write.cc, sccsfile.h: Changed the linebuf member from
	"cssc_linebuf" to "cssc_linebuf*".

	* sid_list.h: Renamed class _linebuf to cssc_linebuf.  Only
	affects the test code for this module.

	* sf-get.cc, sf-delta.cc: Changed the linebuf member from
	"cssc_linebuf" to "cssc_linebuf*".

	* sf-admin.cc: Modified the order in which users are added and
	deleted from the authorisation list for strict compatibility with
	"real" SCCS (fixes bug reported by Richard Polton
	<richardp@scopic.com>).

	* sccsfile.cc: Changed the linebuf member from "cssc_linebuf" to
	"cssc_linebuf*".  Also that class has been changed to much reduce
	the requirement for casts.

	* pfile.cc: Renamed class _linebuf to cssc_linebuf.  Also removed
	the necessity for some casts.

	* sf-rmdel.cc: Renamed class _linebuf to cssc_linebuf.

	* list.h: Code reformatting (whitespace changes only).

	* linebuf.h: Renamed class _linebuf to cssc_linebuf.  Also removed
	the necessity for some casts.

	* linebuf.cc: Renamed class _linebuf to cssc_linebuf and put the
	split() parsing utility function into this class (instead of it
	being a global function).

	* fileiter.cc: Renamed class _linebuf to cssc_linebuf.

	* delta-table.cc: Added some instances of ASSERT(0 != this).

	* sf-prs.cc: Changed the linebuf member from "cssc_linebuf" to
	"cssc_linebuf*".

	* delta-iterator.cc: Added assertions that the dtbl member is not
	NULL.

	* cssc.h: Removed declaration of split() (it's now a member
	function of cssc_linebuf).

	* sf-get2.cc, sf-get3.cc: Added assertions that the delta table is
	not NULL.

	* show-disp.sh: Show disposition of the CVS-controlled files...

1997-12-19  James Youngman  <jay@gnu.org>

	* sccsdiff.sh.in: Modified version of sccsdiff arrived from
	Richard Polton; took the ideas onboard for a rewrite of sccsdiff.

	* tests/sccsdiff/rap.sh: Added test code for sccsdiff from Richard
	Polton "The Rubber Buccaneer" <richardp@scopic.com>

1997-12-12  James Youngman  <jay@gnu.org>

	* tests/large/admin.sh: Check that we can create SCCS files for
	extremely long G-files.

	* tests/admin/users.sh: *** empty log message ***

1997-12-11  James Youngman  <jay@gnu.org>

	* sf-admin.cc: Fixed bug where "admin -a" adds users in exactly
	the opposite order to that required.

1997-11-30  James Youngman  <jay@gnu.org>

	* dtbl-prepend.cc, sccs-delta.cc:
	Code split out of sccsfile.h and sccsfile.cc.

	* delta.h, delta-table.cc, delta-table.h, delta-iterator.cc,
	delta-iterator.h: Split delta-iterator.cc delta-iterator.h
	delta-table.cc delta-table.h delta.h out of sccsfile.h.

	* sf-write.cc, sf-rmdel.cc, sf-prt.cc, sf-prs.cc, sf-get3.cc,
	sf-get.cc, sf-get2.cc, sf-delta.cc, sf-cdc.cc, sf-add.cc,
	sf-admin.cc, sccsfile.h, sccsfile.cc, prt.cc, rmdel.cc, prs.cc,
	delta.cc, get.cc, configure.in, cdc.cc, Makefile.am, admin.cc:
	Split delta.h, delta-table.h, and delta-iterator.h out of
	sccsfile.h to compartmentalise the dependencies.

	* what.cc: Added retuen statement after call to fail() so that the
	compiler stops warning about missing return statements.

	* what.cc, unget.cc, prt.cc, rmdel.cc, my-getopt.h, prs.cc,
	my-getopt.cc, getopt.cc, getopt.h, get.cc, cdc.cc, delta.cc,
	Makefile.am, admin.cc, ChangeLog: Renamed getopt.* to my-getopt.*
	to avoid conflict with systemhader of the same name.



Sun Nov 30 14:10:45 1997  James Youngman  <jay@gnu.org>

	* my-getopt.h: Renamed getopt.h because it conflicts with the Unix
	include file of the same name.  On some systems (e.g. IRIX),
	<stdio.h> includes <getopt.h>.  Since autoconf required that we
	use the preprocessor flag -I., this meant that our C++ header was
	being included by the C programs in testutils.  Hence they did not
	compile.  

Sun Nov 23 12:05:32 1997  James Youngman  <jay@gnu.org>

	* getopt.cc: small changes to eliminate unuseful dependence on
 	quit.h.

	* what.cc: no longer needs quit.h (and in fact what no longer
	needs quit.o).

	* tests/year-2000: added test scripts for Year-2000 compliance.
	They also cover the whole life of SCCS (1969 -- 2038).

	* sccsdate.cc: We now handle dates without using time_t, so that
	everything works with dates right up to 2068.  sccs_date::now()
	still fails when time_t runs out (Tue Jan 19 03:14:07 2038 on my
	system).

	* mktime.c: removed this obsolete file.

	* configure.in: no longer need mktime() or "timezone".

	* sccsname.cc: Fixed bug with 1-character filenames.

	* mystring.h: Use the standard string class from <string>, if it
	is available.

Thu Nov 20 21:03:24 1997  James Youngman  <jay@gnu.org>

	* sccsdate.cc: Added changes mandated by X/Open for year
	2000 compliance, and fixed year-2019 bug. 

	* docs/cssc.texi: Added chapter covering Year 2000 issues to the
 	manual.

Wed Nov 12 00:13:01 1997  James Youngman  <jay@gnu.org>

	* docs/cssc.texi: added TODO comments for text that still needs to
	be written. 

	* docs/TODO: added list of undocumented/unimplemented/untested
	stuff. 

Tue Nov 11 22:11:47 1997  James Youngman  <jay@gnu.org>

	* strerror.c, strstr.c: #include <config.h> not "cssc.h" since the
 	latter contains C++ class definitions and this is a C module.

	* fsync.h, list.h: Don't use double leading underscores in macro
 	names since this conflicts with the implementation's namespace.

	* file.h: Don't munge the names of rename() and remove() since
 	these now no longer have their definitions #included.

	* Makefile.am: Fixed rule for sccsdiff, which did not work on BSD
 	make (since it didn't grok "$<", apparently).

Sun Nov  9 21:06:59 1997  James Youngman  <jay@gnu.org>

	* NEWS: Changes for CSSC-devel-0.03-pl0.

	* Makefile.am:
	Added in some extra garbage to the distribution so that 99.9% of the
	contents of Master-Source goes into the distribution, even unuseful
	stuff like _chmod.cc.  Someone might want it for a port.  Might move
	it into unused/ soon though.

	* configure.in:
	Changed the package number to restore the "devel" label but
	(apparently) conform to the Gnits standard...

	* Makefile.am:
	Added noinst_HEADERS macro so that the header files get put in the
	distribution too.

	* NEWS: Updated for CSSC-0.02-devel-pl7.

	* configure.in: Package name is "CSSC", not "cssc".

	* README: Removed "xxx does not work" for appropriate values of xxx.

	* strstr.c:
	Can't use LIDENT any more to "rename" strstr() since this file is now
	compiled separately.

	* strstr.c:
	No need to guard against multiple inclusion since this is now compiled
	separately.

	* version.cc.in: Initial revision

	* sf-get.cc, sf-delta.cc, sf-admin.cc:
	Don't include strstrr.cc directly; configure now puts it into
	@LIBOBJS@.

	* acconfig.h:
	Include the macros PACKAGE and VERSION to make autoheader happy.

	* configure.in:
	Switched to using "automake".  Also, the config header file produced
	by "configure" is now called "config.h" (what used to be the old
	"config.h" is now part of "cssc.h").

	* cssc.h:
	Got rid of the old config.h file by including its contents directly
	into cssc.h.  Hence the config header file produced by "configure" is
	now called "config.h".

	* Makefile.am: Initial revision

	* configure.in: Some automake changes.   Doesn't really work yet.

	* cssc.h: Merged the contenst of config.h.

Sat Nov  8 23:09:25 1997  James Youngman  <jay@gnu.org>

	* AUTHORS: Initial revision

Sat Nov  8 14:29:45 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Changes to distclean to make sure we don't include generated files in
	the archive if we "make dist" when the source and object dirs are the
	same.

	* Makefile.in:
	To make life easier for those without a copy of "makeinfo", we supply
	a ready-made info file in the distribution.

Fri Nov  7 23:06:06 1997  James Youngman  <jay@gnu.org>

	* sf-admin.cc: sl-merge.cc is now sl-merge.h.

	* configure.in: Also produce pwd/Makefile.

	* sl-merge.h:
	This is now a .h not a .c file.  It had been #included anyway.

	* sid_list.cc:
	Added in most of what had been in sid_list.cc into sid_list.h; this
	had been #included anyway.  The test code is all that's still left in
	the now much shorter sid_list.cc.

	* sid_list.h:
	Added in most of what had been in sid_list.cc; this had been #included
	anyway.  The test code is still left in the now much shorter
	sid_list.cc.

	* list.h:
	Added in what used to be the contents of list.cc; this had been
	#included anyway.

	* admin.cc: Include sid_list.h and sl-merge.h.

	* Makefile.in:
	Use "distclean" target because it is mentioned in INSTALL.
	Also, added "realpwd" and updated the dependencies.

Thu Nov  6 22:37:22 1997  James Youngman  <jay@gnu.org>

	* config.h, cssc.h, defaults.h, file.h, fileiter.h, filelock.h:
	Don't use preprocessor identifiers beginning with two underscores;
	that conflicts with the implementation's namespace.

	* filepos.h: Protect against multiple inclusion.

	* getopt.h, linebuf.h, list.h, myconfig.h, mystring.h, pfile.h, pipe.h, quit.h, run.h, sccsdate.h, sccsfile.h, sccsname.h, seqstate.h, sf-chkmr.h, sid.h, sid_list.h, stack.h, sysdep.h, xalloc.h:
	Don't use preprocessor identifiers beginning with two underscores;
	that conflicts with the implementation's namespace.

Wed Oct 29 23:01:43 1997  James Youngman  <jay@gnu.org>

	* mkinstalldirs, COPYING: Initial revision

	* Makefile.in:
	FreeBSD's "make" doesn't define "RM" by default.  So provide that
	definition.

Tue Oct 28 22:43:40 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	By default, only generate the info file and not the DVI file also.

Mon Oct 27 19:28:00 1997  James Youngman  <jay@gnu.org>

	* sf-get.cc:
	write_subst(): take as a parameter the delta which is actually being
	gotten, so that keyword substitution is correctly carried out.

	* sccsfile.h, sf-admin.cc, sf-delta.cc:
	Use the no_id_keywords() member function to indicate that situation
	(which might result in either a fatal error or just a warning,
	according to the setting of the "i" flag).

	* sf-get2.cc:
	write_subst(): take as a parameter the delta which is actually being
	gotten, so that keyword substitution is correctly carried out.  Also,
	use the no_id_keywords() member function to indicate that situation
	(which might result in either a fatal error or just a warning,
	according to the setting of the "i" flag).

	* Makefile.in:
	Added sf-kw.cc for get, delta and admin.  Also added targets for
	testing each program separately.

	* sf-kw.cc: Take as a parameter the name of the file.

Sun Oct 26 19:48:06 1997  James Youngman  <jay@gnu.org>

	* sf-kw.cc: Initial revision

	* get.cc: The -m and -n options had been the wrong way around.

	* what.cc: Made the output format match that of the real thing.  Most
	importantly, we no longer emit the initial @(#).

Sat Oct 25 16:53:26 1997  James Youngman  <jay@gnu.org>

	* README:
	Modified the example scripts for compiling the package, in such a way
	that I get more information if there is some failure.  Also, update
	the name of the GNU domain; this has changed from gnu.ai.mit.edu to
	gnu.org.

	* Makefile.in: Added canonify.cc to the sources for making "get".

	* sid.h, sid.cc:
	Sometimes we _always_ want the SID component to be printed, even if it
	is zero.  Examples of this include the %R%,%B%,%L% and %S% keywords
	expanded by sccs-get.  An extra argument (with a default) has been
	added to sid::printf().  The default behaviour is the same as the old
	behaviour.

	* sf-get2.cc:
	Corrected the expansions of the %R%, %L%, %B%, %S% and %P% keywords.
	(Also have a new test file, get/subst.sh, to test these).

	* sccsname.h:
	Added prototype for canonify_filename(), which is used in sf-get2.cc,
	to expand the %P% keyword.

	* mystring.h, mystring.cc:
	Added an operator[], which returns a const char&.

	* canonify.cc:
	canonify_filename() now takes a const char* as its argument.

	* canonify.cc: Initial revision

Mon Aug 11 21:35:36 1997  James Youngman  <jay@gnu.org>

	* mystring.h: Patches from Fila Kolodny <fila@ibi.com> to support
 	snapshots of GCC after 2.7.2.2.

Thu Jul 17 08:39:42 1997  James Youngman  <jay@gnu.org>

	* tests/common/test-common: Fixed typo (which had caused echo -e
 	bug on Solaris).

Tue Jul 15 18:59:52 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped patchlevel (Solaris /bin/sh portability).

Tue Jul 15 07:04:02 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Bumped patchlevel (lndir now is happy if source & dest are the same).

Mon Jul 14 21:40:20 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped the version number -- another prerelease, 0.02.

	* Makefile.in:
	Made it possible to run "make dist" from the work dir.  That way, an
	already-created makefile will be used.  No actual files from the work
	directory are included in the distribution.

	* Makefile.in: Make in "lndir" too.

	* configure.in: sub-configure in "lndir" too.

Thu Jul 10 20:31:17 1997  James Youngman  <jay@gnu.org>

	* README: Provided quick-start info and a reference to docs/TESTING.

Thu Jul 10 20:17:31 1997  James Youngman  <jay@gnu.org>

	* sf-prt.cc, sccsfile.h, sccsfile.cc:
	Horrible hack to support "empty" include/exclude lists for deltas so
	that prt can be completely faithful to the SCCS command of the same
	name.

Wed Jul  9 21:59:21 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped to 0.01-devel-pl13.

Mon Jul  7 21:36:15 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Small correction to all-tests target.

	* Makefile.in:
	Don't hardwire $(prefix).  Also rationalised testing targets.

	* run.h:
	Use USE_PIPE not HAVE_PIPE because HAVE_FORK is also required in order
	for USE_PIPE to e sensible.

	* acconfig.h: Add explanation of HAVE_FORK.

	* pipe.h, sf-delta.cc, pipe.cc:
	Use USE_PIPE not HAVE_PIPE because HAVE_FORK is also required in order
	for USE_PIPE to e sensible.

	* configure.in:
	Treak fork() specially since we have to avoid it on AmigaOS.

	* quit.cc:
	Use USE_PIPE not HAVE_PIPE because HAVE_FORK is also required in order
	for USE_PIPE to e sensible.

	* run.cc: Try to cope with the almost-completely-useless semantics of
	system()...MR validation on systems without fork() or spawn() is
	broken.

Wed Jul  2 18:21:52 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped patchlevel (attempted IRIX fix)

Wed Jul  2 18:18:44 1997  James Youngman  <jay@gnu.org>

	* quit.cc, prs.cc, prompt.cc, pipe.cc, pfile.cc, pf-del.cc,
 	pf-add.cc, mystring.cc, list.cc, linebuf.cc, l-split.cc,
 	getopt.cc, get.cc, fsync.cc, fileiter.cc, file.cc, delta.cc,
 	cdc.cc, admin.cc, _chmod.cc:
	Oops.  Removed line that should not have been in the header.

	* xalloc.h, sysdep.h, stack.h, sid_list.h, sid.h, sf-chkmr.h,
 	seqstate.h, sccsname.h, sccsfile.h, sccsdate.h, run.h, release.h,
 	rel_list.h, quit.h, pipe.h, pfile.h, mystring.h, myconfig.h:
	Updated the copyright header.

	* myconfig.h: Initial revision

	* list.h, linebuf.h, getopt.h, filelock.h, fileiter.h, file.h,
 	defaults.h, xalloc.cc, what.cc, unget.cc, strstr.cc, split.cc,
 	sl-merge.cc, sid_list.cc, sid.cc, sf-write.cc, sf-rmdel.cc,
 	sf-prs.cc, sf-get3.cc, sf-get2.cc, sf-get.cc, sf-delta.cc,
 	sf-chkid.cc, sf-cdc.cc, sf-admin.cc, sf-add.cc, sccsname.cc,
 	sccsfile.cc, sccsdate.cc, sact.cc, run.cc, rmdel.cc, rl-merge.cc,
 	rel_list.cc, quit.cc, prs.cc, prompt.cc, pipe.cc, pfile.cc,
 	pf-del.cc, pf-add.cc, mystring.cc, list.cc, linebuf.cc,
 	l-split.cc:
	Updated the copyright header.

	* getopt.cc: Updated the copyright header.
	Also made the class members non-inline to appease IRIX.

	* get.cc, fsync.cc, fileiter.cc, file.cc, delta.cc, cdc.cc,
 	admin.cc, _chmod.cc:
	Updated the copyright header.

	* sf-prt.cc:
	It seems that -b doesn't turn off the printing of the delta table,
	after all.

	* sccsfile.cc, sf-prt.cc:
	Ue SEEK_SET instead of the manifest constant zero for fseek().
	Include <unistd.h> to get it, on SunOS.

	* filepos.h:
	Ue SEEK_SET instead of the manifest constant zero for fseek().

Wed Jul  2 06:55:16 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Portability fixes for Solaris and SunOS; make sure libsubst.a is never
	empty (Solaris ld doesn't like empty libraries), fall back on
	fseek()/ftell() in the absence of fsetpos()/fgetpos().

	* sf-prt.cc:
	Use the helper class FilePosSaver to encapsulate fgetpos() or the lack
	of it.

	* filepos.h: Initial revision

	* configure.in, acconfig.h: Added HAVE_FSETPOS.

	* dummy.cc: Initial revision

Tue Jul  1 07:56:48 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Bumped to patchlevel 10 (we were installing cssc.info in the root
	directory!)

Mon Jun 30 22:15:07 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped to CSSC-0.01-devel-pl9 prior to release.

	* INSTALL:
	Replace the original (MySC) INSTALL file with the generic one suitable
	for Autoconf-generated "configure" files.

	* move-if-change: Initial revision

	* Makefile.in:
	Moved version info into vernum.h, which is an auto-generated file.
	We now avoid re-building version.o and relinking everything, if the
	actual version information is unchanged.   Also support tar'ing the
	RCS files into a separate tar file for possible distribution.

	* version.h: Initial revision

	* version.cc:
	Moved version info into vernum.h, which is an auto-generated file.

	* Makefile.in: Support "make install".

Sun Jun 29 10:47:08 1997  James Youngman  <jay@gnu.org>

	* configure.in: Put the *.cs files into the directory "shorter".

	* Makefile.in: Added "prt" as a target.

Sun Jun 29 09:38:21 1997  James Youngman  <jay@gnu.org>

	* docs/Makefile.in:
	Make PostScript output (A4 by default) too.  Support Letter-sized
	paper as well.

	* docs/gpl.texinfo: Initial revision

	* docs/cssc.texi: Put the copy of the GPL back in.

Sat Jun 28 15:12:58 1997  James Youngman  <jay@gnu.org>

	* docs/cssc.texi:
	MR numbers do not have to be numbers.  Added "Known Problems"
	section.  Added remarks about how to encode files sent with bug
	reports.

Sat Jun 28 14:40:04 1997  James Youngman  <jay@gnu.org>

	* prt.cc: Always print the s.file's name, even of there is only one.

	* sf-prt.cc:
	Several fixes to do with the arrangement of whitespace.  Also, say
	"none" if we have no flags.

Fri Jun 27 18:51:22 1997  James Youngman  <jay@gnu.org>

	* sccsfile.cc: Added next_seqno(), used by delta.

	* sf-delta.cc:
	Working creation of null deltas; this version doesn't break branching
	(in absence of null deltas).

	* sccsfile.h: Added next_seqno(), used by delta.

Mon Jun 23 23:02:47 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Added rl-merge.cc.

	* sid.h: Moved operator release() elsewhere.

	* sid.cc: Moved release::release(const sid&) elsewhere.

	* release.h: Added release(const sid&).

	* sf-delta.cc: Preliminary support for null deltas.

Tue Jun  3 20:23:40 1997  James Youngman  <jay@gnu.org>

	* sccsfile.h:
	Provide sid_in_use(), initially for use by find_next_sid().

	* quit.h, quit.cc:
	Added the function name to the information given when an assertion
	fails, for GCC only.

	* get.cc:
	sccs_file::find_requested_sid() needs to pass back some information if
	the requested sid was either unspecified or specified the release
	number only.

	* sid.h: Added sid::next_level(), initially for use by
	sccs_file::find_next_sid().

	* sf-get2.cc:
	Better support for branching and a stab at support for the joint-edit
	flag.

Mon Jun  2 23:07:11 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc:
	Reworked find_next_sid(), which decides what SID we'll put in the
	p.file.

Sun Jun  1 20:39:03 1997  James Youngman  <jay@gnu.org>

	* sid.h, sid.cc:
	Provide new methods on_trunk(), matches(), and components(), initially
	for use by sccs_file::find_requested_sid().

	* sf-get2.cc:
	Rewrote get_requested_sid() to be shorter, provide behaviour closer to
	SCCS, and to allow for later support of get's -t option.

	* release.h:
	Provide informational enum member LARGEST, denoting the largest valid
	release number.

	* sccsfile.h:
	Find_requested_sid() needs to know wether it should look along
	branches, so provide that as a parameter.

	* sf-admin.cc:
	The "fixes" for id-keyword processing had accidentally ensured that we
	only read the first line of the input file :-)

	* sccsfile.cc, sccsfile.h: Added sccs_file::delta::removed().

	* sf-get2.cc:
	Correctly handle "get -r99" when there is only one revision in the
	file.

Sun Jun  1 00:36:37 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped the patchlevel to CSSC-0.01-devel-pl6

Sun Jun  1 00:32:11 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Updated the dependencies.

	* sf-prt.cc: Fixed small bug with empty string flags.

	* release.h: print() needs to return zero for success.

Sat May 31 23:30:27 1997  James Youngman  <jay@gnu.org>

	* sccsfile.cc:
	Support empty 'i', 'x', and 'g' control lines with no argument.   This
	serves no purpose, but these do turn up.

	* sf-prt.cc:
	Support -i (list included/excluded deltas) and the printing of MRs and
	comments (i.e. -d as opposed to -s).

	* sf-prs.cc, sf-get3.cc, sf-get2.cc, prs.cc, get.cc, sccsfile.h:
	Changed variables named "cutoof" to "cutoff_date" to avoid the new
	struct cutoff inside sccs_file.

	* sccsfile.cc:
	Added a version of find_most_recent_sid() that works purely
	chronologically rather thann along a branch.

	* sccsfile.h:
	A version of find_most_recent_sid() that works purely chronologically
	rather thann along a branch, plus support sccs_file::cutoff, a reified
	object encapsulating cutoff dates and SIDs for programs like sccs-prt
	and sccs-prs.

	* sccsdate.h: valid() can be a const member of sccs_date.

	* sf-prt.cc:
	Working support for cutoff dates and SIDs, plus printing the body of
	the file.

	* prt.cc: Working support for -c, -r, -y and also -b (print body).

Sat May 31 10:27:10 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	New source files rel_list.cc, rl-merge.cc, and sysnerr.h.  Renamed
	$(LFLAGS) to $(LDFLAGS).

	* sf-delta.cc, sf-get.cc: Fixes for id-keywords-flag processing.

	* quit.cc:
	Obtain declarations of sys_nerr and sys_errlist from our own header
	sysnerr.h, which used macros generated by "configure".

	* admin.cc: Support naked -i, -m, and -y options.  Hence remove
 	the -I, -M, and -Y options.

	* prt.cc: Initial revision

	* sccsfile.cc, sf-write.cc: Fixes for id-keywords-flag processing.

	* release.h: Initial revision

	* sid.h: Reimplemented the class release_list.

	* sf-admin.cc:
	Fixes for id-keywords-flag processing, and support the naked "y"
	option, which inhibits the default comment.

	* sf-get2.cc: Fixes for id-keywords-flag processing.

	* rl-merge.cc, rel_list.h, rel_list.cc: Initial revision

	* sf-prs.cc:
	Fixes for id-keywords-flag processing.  Reimplemented the class
	release_list.

	* sccsfile.h: Support "prt".  Fixed for id-keywords-flag
 	processing.  Use rel_list.h since we have now reimplemented the
 	class release_list.

	* sf-prt.cc: Initial revision

Tue May 27 20:16:39 1997  James Youngman  <jay@gnu.org>

	* sysnerr.h: Initial revision

	* unget.cc: Actually SCCS _doesn't_ print the locked SID twice, I
 	was mistaken :-(

Sun May 25 15:34:00 1997  James Youngman  <jay@gnu.org>

	* unget.cc:
	Modified the output format to be closer to that of SCCS.  We're still
	not there, and the current "unget" test script fails for us (it passes
	for SCCS).

	* fileiter.cc, fileiter.h:
	Added unique() which returns nonzero if we're in the situation where
	the utilities don't need to print out the name of the SCCS file
	they're working on because it's unambiguous -- that is, exactly one
	was specified on the command line.

	* pfile.h:
	Added print_lock_sid, which prints the SID of the lock that "pos"
	refers to (the SID of the delta not the SID of the gotten revision).

	* pfile.cc:
	Added print_lock_sid, which prints the SID of the lock that "pos"
	refers to.

Fri May 23 00:11:28 1997  James Youngman  <jay@gnu.org>

	* Support "admin -t" with no argument.

	* Makefile.in (docs/Makefile): Need installdocs target.

Wed May 21 00:06:46 1997  James Youngman  <jay@gnu.org>

	* linebuf.h, linebuf.cc:
	Small changes (not actually to executable code) to allow the sid_list
	test code to work.

	* sl-merge.cc:
	Much fixing with regard to sid_lists.  Construction from,
	comparison with, and assignment from NULL are sins no longer
	committed.  Also, the nested class "range" is now a separate template
	class.

	* sid.cc:
	The branch and sequence components of trunk revisions are supposed to
	be blank.  Also some small changes (not actually to executable code)
	to allow the sid_list test code to work.

	* getopt.cc:
	Invented the '!' modifier, similar to ':', but allowing empty
	options.  Note that this is to support empty -m and -y options for
	admin and delta, that this behaviour is for compatibility with "real"
	SCCS, and is unlike traditional or POSIX option processing.

Tue May 20 23:58:56 1997  James Youngman  <jay@gnu.org>

	* delta.cc: Support for empty -m and -y options.

	* admin.cc:
	If admin is given a bare -y option, this means that NO comments are to
	be entered into the SCCS file for the initial delta.  This is distinct
	from the situation when no -y option is given, when a "date and
	time created..." entry is added.  Hence the suppress_comments flag
	needs to be passed down into sccs_file::create(), which is where that
	message is normally added.

	* sf-prs.cc:
	Many, many fixes involving the output format for flags that are not
	set, plus backslash escape processing has been implemented, as in
	"real" SCCS.

	* sf-admin.cc:
	If admin is given a bare -y option, this means that NO comments are to
	be entered into the SCCS file for the initial delta.  This is distinct
	from the situation when no -y option is given, when a "date and
	time created..." entry is added.  Hence the suppress_comments flag
	needs to be passed down into sccs_file::create(), which is where that
	message is normally added.

	* sf-write.cc, sccsfile.h:
	Construction from, comparison with, and assignment from NULL are sins
	no longer committed with sid_lists.

	* pfile.h:
	Use range_list<>'s empty() method, not comparison with NULL, to find
	out if it empty.

	* sid_list.cc, sid_list.h:
	Much fixing with regard to validity checks.  Construction from,
	comparison with, and assignment from NULL are sins no longer
	committed.

Mon May 19 18:57:22 1997  James Youngman  <jay@gnu.org>

	* sid_list.h: Eliminate range_list<>::operator=(void*), since it
	is a carbuncle -- see comments in sid_list.h.

Sat May 17 12:19:02 1997  James Youngman  <jay@gnu.org>

	* run.cc:
	If run_mr_checker() is called (because the v flag is set) but the PRG
	argument is empty (i.e. the flag is set to the empty string), the
	validation silently succeeds.

	* delta.cc:
	Fixed bugs involving MRs.  We now output the delta's SID to stdout even
	though the delta fails, because that's what SCCS does.  More
	importantly, if the MR validation flag is set, but has no value, MRs
	are prompted for and allowed (with the -m option) but no actual
	changing is done -- they are always assumed valid.

Fri May 16 08:04:08 1997  James Youngman  <jay@gnu.org>

	* Support tests for MR number processing and interactive comments
	for delta (but the latter is only done if stdin is a tty...)

Thu May 15 21:51:57 1997  James Youngman  <jay@gnu.org>

	* l-split.cc:
	Fixed split_mrs().  It now calls strtok correctly and frees the right
	thing.  I don't see how it could ever have previously worked...but I
	don't know that it did.

Tue May 13 17:40:15 1997  James Youngman  <jay@gnu.org>

	* get.cc:
	Sense of the variable "keywords" was inverted.  We now suppress
	keyword expansion for -e and -k, and do expansion otherwise, not vice
	versa.

Sat May 10 14:50:00 1997  James Youngman  <jay@gnu.org>

	* almost all files: changed the package name

	* version.cc: Modified the version strings so that they show up with
	RCS ident and SCCS/CSSC's what, and also are human-readable.

	* cssc.h: Moved the version() function into version.h.

	* sccsfile.cc: Fixed problem with updating our notion of hogh_release.

	* sf-delta.cc:
	Output the inserted/deleted/unchanged lines, just like "real" SCCS.

	* get.cc:
	Go for output compatibility when reporting Included/Excluded deltas,
	and actually make the output the same.

	* Tested the test scripts themselves against the real thing, and
	hence fixed them, and hence made some changes to CSSC, mostly in
	the exact format of the output (sccsfile.cc, sf-delta.cc, get.cc).

Wed May  7 23:39:49 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc: find_requested_sid: Fix a bug in the case where
 	there is only one SID (1.1) in the file and no -r is specified on
 	the command line (i.e requested.is_null() is true).

Sun May  4 17:01:36 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc: Fixed the behaviour when no -r is given or the -r
 	that is given is of the form -rX or -rX.Y.Z (see docs/get-spec.txt
 	and tests/get/sid-select.sh)

	* Makefile.in: Added sccsdiff to $(CMDS).

	* Makefile.in:
	Added a rule for creating sccsdiff.sh from sccsdiff.sh.in.

	* configure.in:
	Find the pr(1) program and substitute for it in sccsdiff.sh.in.

	* file.cc: Corrected usage of freopen(), which returns NULL on failure.

	* sccsdiff.sh.in:
	Have to enclose the version string in single rather than double
	quotes, to protect the dollar signs from shell expansion.

	* sccsdiff.sh.in: Initial revision

Sun May  4 12:11:02 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc: Bugfix for behaviour with "-e -r2" when latest trunk
	revision was 1.x.  This used to get a delta from 1.x, now it
	creates the new delta 2.1, as does "real" SCCS.

Sat May  3 22:42:55 1997  James Youngman  <jay@gnu.org>

	* get.cc:
	Added support for the -G option (standard and used by, for example,
	GNU make).

	* sf-get2.cc:
	If no SID is specified with -r, and no SID id specified in the file as
	the default, use the one furthest down the trunk from 1.1.  Don't
	return one on a branch.

Sat May  3 17:17:38 1997  James Youngman  <jay@gnu.org>

	* sf-get.cc:
	Support SCCS files whose first referred-to delta is not numbered 1.
	SunOS can produce these.

	* sf-write.cc, sf-prs.cc, sf-admin.cc, sccsfile.h, sccsfile.cc:
	Added support for the 'e' (encoded) flag.

Sat May  3 11:51:53 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc:
	In sccs_file::find_requested_sid(), if the requested sid is 0.0.0.0
	(i.e. is_null()), accept the first sid we find as the first guess at
	the best match (but continue to look). [oops, bad idea, see above!]

	* sid.h:
	Fixed bug in the conditionals for sid::valid() and release::valid().

	* Makefile.in: Added dependencies.

Tue Apr 29 01:42:14 1997  James Youngman  <jay@gnu.org>

	*: Decided to consider supporting setuid execution via BSD's
 	sccs(1) command.

Sun Apr 20 22:38:13 1997  James Youngman  <jay@gnu.org>

	* file.cxx: What about support for set-Group-ID execution?
	

	2001-11-23  james_youngman  <james_youngman@periwinkle.no.where>

	* /cvsroot/cssc/gnu/CSSC/tests/prs/format.sh:
	Initial version - qworks on Solaris SCCS, not on CSSC.

	Give up privileges while manipulating the g-file, because the g-file
	is owned by the euid of the process which invoked "get", not by the
	set-user-id ownfer of the "get" file.  This is related to Sourceforge
	bug ID 458485.

	* /cvsroot/cssc/gnu/CSSC/file.cc:
	Minor correction to error message in set_file_mode() (don't have a
	newline in the middle of it).

	* /cvsroot/cssc/gnu/CSSC/tests/get/included.sh:
	SourceForge bug number 441423: on NetBSD-1.5W, the sed "a" command
	appears to eat the newline.  Hence we replace the old single-step sed
	command above with a three-step approach which doesn't use "a".

	* /cvsroot/cssc/gnu/CSSC/docs/cssc.texi:
	Added sensible header to HTML output; indicate the version number in

	Provide new configure option, --disable-binary, which removes support
	for creating binary SCCS files.  If we find an existing binary SCCS file,
	we can still work with it.   Also allow the setting of a maximum line length
	in order to provide better interoperability with other SCCS implementations.

	Fix for long-standing bug: we now can correctly extract
	files containing deltas which include other deltas with
	the ^Ai construct (e.g. branch merges).  We may still not
	handle "get -i" correctly yet though.  Also, no similar
	fix for the excluded delta situation (I have no example
	file demonstrating that problem).  This is recorded as
	SourceForge bug 111140.  A test for this bug is also now
	included.

	* /cvsroot/cssc/gnu/CSSC/configure.in:
	A test commit, changing the suffix on the version number (to emphasise
	the fact that it's the CVS code).  Real purpose is to test the CVS checkin
	notification facility.

2000-11-12  James Youngman  <james_youngman@users.sourceforge.net>

	* /cvsroot/cssc/gnu/CSSC/fatalsig.cc:

2000-08-05  James Youngman  <james_youngman@users.sourceforge.net>

	* /cvsroot/cssc/gnu/CSSC/show-disp.sh:
	Updated copyright year and added ID header comment.

	* /cvsroot/cssc/gnu/CSSC/show-disp.sh:
	Use the -z3 option to compress data for "cvs status" because we have a
	long link with low bandwidth, often.  However, we don't use -z9
	because that would be worse for faster links.

	* /cvsroot/cssc/gnu/CSSC/NEWS, /cvsroot/cssc/gnu/CSSC/configure.in:
	Added in information about recent changes.

	* /cvsroot/cssc/gnu/CSSC/docs/cssc.texi:
	Resolved conflict on line containing the URL of the CSSC bug reporting page.

	* /cvsroot/cssc/gnu/CSSC/tests/get/sid-select2.sh:

	* /cvsroot/cssc/gnu/CSSC/bsd/sccs.c:
	Patch from Albert John FitzPatrick III  <ajf_nylorac@acm.org>;
	Added support for "unget".

	* /cvsroot/cssc/gnu/CSSC/delta.cc:
	Accept list of MRs on input even if the input is not a TTY since
	allegedly other implementations do this.

2000-03-19  James Youngman  <jay@gnu.org>

	* tests/get/subst.sh, sf-get2.cc, sid.cc, sid.h:
	Patches from Mark Fortescue relating to SID selection and cutoff dates.

	* relvbr.h:
	Removed remarks about MySC, since this file has never been part of MySC.

	* relvbr.h: Fix by Mark Fortescue <mfortescue@transoft.com>.

	* rmdel.cc, cdc.cc: Fix from Frank van Maarseveen <fvm@tasking.nl>:

	A setuid cdc/rmdel will not unlock (i.e. remove the z-file) in
	case of an error. Most obvious error is when the invoker is not
	the creator of the delta.

	Both cdc and rmdel revoke setuid permission when the real user
	is not the creator of the delta. However, this should be restored
	_before_ reaching the end of the 'try' scope because on leaving
	it the z-file is removed indirectly by the sccs_file destructor.

	Attached you will find a patch which solves this problem.

	A more correct solution would be not to swap uid/euid but
	to print something like:

	ERROR [/usr/src/xxx/SCCS/s.main.c]:
	Must be owner of file or <user> to use this command.(rc4)

	* docs/cssc.texi:
	Support for SCCS files in which timestamps have been corrupted by
	non-Y2K-compliant versions of SCCS.  These files are correctly
	understood on reading, and are fixed if the file is ever re-written by
	CSSC.  (The Sun version of SCCS also performs the same fix).  Patches
	to do this were provided by Peter Kjellerstedt

	* delta-table.cc, delta-table.h, sf-get2.cc:
	Sergey Ostashenko provided patches to allow the processing of SCCS
	files with gaps in the chain of used sequence numbers, and to allow
	two deltas to have the same sequence number, on the condition that one
	of them is a removed delta.

	* sccsdate.cc:
	Patch by Peter Kjellerstedt for cleaning up after broken versions of
	SCCS.

	Some non y2k-compliant versions of SCCS will use a ":" in the decade
	field of the date in the year 2000 (since the ASCII code for ':' is
	one greater than that for '0').  Changed the relevant sccs_date
	constructor to figure out the right value in this case.  A warning
	message is issued when this happens.

	Improved the error message which is issued when you try to open a
	nonexistent SCCS file.

	* docs/CREDITS, docs/CREDITS.short.txt, docs/Platforms:
	Bugfixes from Hyman Rosen and Mark Reynolds

	* sf-get.cc:
	Mark Reynolds <mark@aoainc.com>: GCC 2.8.1 on VAX Ultrix 4.2 doesn't
	seem to get this call right.  Since subst_fn is always write_subst
	anyway, we work around it by using the function pointer just as a
	boolean variable.  Yeuch.

	* bsd/sccs.c:
	Mark Reynolds <mark@aoainc.com>: If $LANG is not set, setlocale()
	fails on VAX Ultrix 4.2.

1999-06-26  James Youngman  <jay@gnu.org>

	* tests/admin/lockfail.sh:
	Fail correctly, but don't coredump, when we fail to create a lock file.
	Bug report by Michael Ubell <ubell@mindspring.com>.

	* tests/admin/lockfail.sh: New file.

	* file.cc, sccsname.h:
	Fail correctly, but don't coredump, when we fail to create a lock file.
	Bug report by Michael Ubell <ubell@mindspring.com>.

	* run.cc: Fixed typos.

	* tests/cdc/2comment.sh, tests/cdc/4order.sh:
	Use egrep, not grep, because on SunOS 4.1.3, grep(1) doesn't like the
	long regexps...

	* run.cc: SunOS 4.1.3 doesn't like fflush(NULL). (Mark Reynolds)

	* testutils/seeker.c, testutils/lndir.c:
	Vax Ultrix 4.2 requires <sys/types.h>. (Mark Reynolds)

	* sccsfile.cc: Compatibility fixes provided by Hyman Rosen.

	* val.cc: Fixed the name of the executable passed to set_prg_name().

1999-04-21  James Youngman  <jay@gnu.org>

	* ChangeLog: Added changes to date.

	* seqstate.h, seqstate.cc: Removed dependency on the STL <list> header.

1999-04-18  James Youngman  <jay@gnu.org>

	* docs/texinfo.tex: Automake likes texinfo.tex to be present.

	* delta.h, dtbl-prepend.cc, fileiter.h, prs.cc, prt.cc,
	rel_list.cc, rel_list.h, rl-merge.cc, rmdel.cc, run.h, sact.cc,
	seqstate.cc, seqstate.h, sf-cdc.cc, sf-chkmr.h, sf-get.cc,
	sf-get3.cc, sf-prs.cc, sf-prt.cc, sf-rmdel.cc, sf-write.cc,
	unget.cc, ChangeLog, delta-table.cc, delta-table.h: Updated
	copyright statements for those files modified this weekend.

	* configure.in:
	Commented out AM_PROG_INSTALL, since automake seems not to like it
	any more.

	* tests/bsd-sccs/driver-basic.sh:
	Disable test h2, since currently we don't pass it.   FIXME!

	* tests/rmdel/basic.sh: *** empty log message ***

	* tests/bsd-sccs/driver-basic.sh:
	Added test for "sccs unedit" ensuring we delete the gotten file.

	* docs/Platforms, docs/TODO, auxfiles/CSSC.spec.in:
	*** empty log message ***

	* pfile.cc, pfile.h, prs.cc, prt.cc, quit.cc, rel_list.cc,

	delta.cc, delta.h, dtbl-prepend.cc, fileiter.h, get.cc,
	l-split.cc, list.cc, mylist.h, mystring.h: Changes for correct
	support of included deltas in branches (a rewrite of seqstate.cc
	and seqstate.h).

	Enable the test, now that we support included non-ancestor branches.

	* NEWS, README, configure.in: Updates for 0.11alpha.pl0

	* docs/cssc.texi: Updated version for next release.

	* docs/BUGS: Added bug report for "unget" deleting the wrong g-file.

	* bsd/sccs.c: Use tmpfile() rather than mktemp() in unget(), because
	glibc-2.1-0.990311 has a broken mktemp() (it returns an empty string).

1999-03-29  James Youngman  <jay@gnu.org>

	* tests/get/included.sh: Tests for included deltas.

1999-03-21  James Youngman  <jay@gnu.org>

	* auxfiles/CSSC.spec.in:
	Folded in change from Michael Sterrett <msterret@coat.com> and Aron
	Griffis <agriffis@coat.com> which puts symlinks in /usr/bin (or
	whatever directory), pointing at the stuff in /usr/libexec/cssc.
	The effect is to have /usr/bin/get and so on.

	* bsd/sccs.c:
	Applied patch from Greg A. Woods which eliminates compiler warnings
	from sccs.c, without changing how the program works (I hope!).

	* docs/Platforms: Updated with respect to C++ compiler compatibility.

	* configure.in: Moved version.cc to the front of the AC_OUTPUT() list.

	* run.cc: Modification from Greg A. Woods; eliminates compiler warning.

	* docs/cssc.texi: Updated version number.

	* bsd/sccs.c, docs/cssc.texi, delta.cc, configure.in:
	Updated copyright messages of those files edited so far in 1999.

	* tests/prs/keywords.sh: Use "echo_nonl" instead of "echo -n".

	* configure.in, ChangeLog, NEWS: Go to 0.10beta-pl0 from 0.09alpha-pl4.

	* docs/cssc.texi:
	Cosmetic changes to make texinfo-3.12f happy about my use of @xref.
	(in this case, by adding punctuation after each use).

1999-03-19  James Youngman  <jay@gnu.org>

	* testutils/realpwd.cc, sf-delta.cc, sf-get2.cc, sid.cc, what.cc, bodyio.cc, cdc.cc, delta-iterator.cc, my-getopt.cc, mystring.cc, mystring.h, pfile.h, quit.cc, quit.h, run.cc:
	Fixes to make CSSC compiler under the EPC C++ compiler (and probably
	other C++ compilers, too).

1999-03-15  James Youngman  <jay@gnu.org>

	* Released 0.09alpha.pl4.

	* ChangeLog, NEWS, configure.in: Comments etc. for 0.09alpha.pl4.

	* docs/cssc.texi: Marginally improved documentation for "delta -p"

1999-03-14  James Youngman  <jay@gnu.org>

	* docs/cssc.texi, ChangeLog, delta.cc, sccsfile.h, sf-delta.cc:
	Implemented the -p option of delta.

	* docs/TODO:
	Added tests to make sure we correctly count the number of lines initially inserted by admin -i.

	* bsd/sccs.c: Tweaks to execv() usage in try_to_exec().
	Also, ensure that PREFIX is absolute, and refuse to run otherwise.

	* configure.in: Eliminate duplicate checks for abort() and wait().

	* auxfiles/CSSC.spec.in: Corrected the URL.

	* tests/delta/n-option.sh: Added tests for the -n option of delta.

	* tests/admin/i-option.sh:
	Check that the "initial number of lines" is correct for admin -i.

1999-03-13  James Youngman  <jay@gnu.org>

	* configure.in: Bumped to 0.09alpha.pl3.

	* NEWS: Added NEWS remark regarding the removal of AC_C_CONST.

	* tests/admin/r-option.sh: val has now been implemented.

	* docs/TODO, docs/cssc.texi, docs/missing.txt, sccsfile.cc, sccsfile.h, sf-admin.cc, sf-delta.cc, what.cc, NEWS, admin.cc, configure.in, file.cc, get.cc, pfile.cc, quit.cc, run.cc:
	Allow "admin -ifoo -r1.2.2.1 s.foo", and make it work correctly.
	Also added tests for the -r option.

	* tests/admin/init-mr.sh: Corrected an error message.

1998-12-12  James Youngman  <jay@gnu.org>

	* docs/cssc.texi:
	Warn that "admin -z" may silently fix errors and get it wrong.

	* val.cc, sf-val.cc, sf-write.cc, quit.cc, quit.h, sccsfile.cc, except.h, file.cc, get.cc, bodyio.cc, delta-table.cc:
	Enhancements to "val".

1998-12-10  James Youngman  <jay@gnu.org>

	* configure.in: Went to 0.09alpha.pl2.

1998-12-09  James Youngman  <jay@gnu.org>

	* NEWS: Added news for CSSC-0.09alpha-pl2.

	* sccsfile.h:
	Added declarations of functions implemented in sf-val.cc and also a
	forward declaration of class delta_iterator.

	* what.cc: Duh.  getchar() returns int, remember?

	* sf-prt.cc:
	If a (mystring*) flag in the SCCS file is not NULL, then the flag must
	be set even if the length of the string is zero; consider lines like
	"^Af v" rather than "^A f v ".

	* sid.h, sid.cc: Implemented sid::as_string().

	* sccsfile.cc:
	We have to be careful to not crash on input lines like "^Af v".  That
	is, bufchar(4) may well be zero for a flag line!  Thanks to William
	W. Austin <bill@baustin.alph.att.com> for this diagnosis.

	* sf-val.cc:
	Traverse the delta table checking some things.  Not finished yet.

1998-11-29  James Youngman  <jay@gnu.org>

	* docs/cssc.texi, docs/TODO, val.cc, sf-val.cc, sccsfile.h, Makefile.am, NEWS:
	Initial implementation of "val".

	* sf-admin.cc: Make it possible to delete the "m" flag.

	* valcodes.h: Return codes for "val".

	* docs/CREDITS: Fixed typo.

1998-11-21  James Youngman  <jay@gnu.org>

	* admin.cc: Ensure that if we specified -h, we do *nothing* else.

	* tests/admin/admin-hz.sh:
	Make sure that if we specify -h and -z, we do not update the checksum.

	* tests/admin/admin-hz.sh:
	Added tests for the -h and the -z options of admin.

	* docs/cssc.texi: Elaborated on comments about "admin -z".

	* sf-get.cc:
	For get(), ensure that the file was not opened with the mode
	FIX_CHECKSUM, because that doesn't make sense.

	* sccsfile.cc:
	Emit helpful message if we fail to open the s-file.   If we are doing
	"admin -z", don't complain if the checsum was previously wrong.

	* sccsfile.h: Added new open mode FIX_CHECKSUM.

	* admin.cc: Better operation of the -z (reset checksum) option.

	* sf-write.cc:
	Rethought update_checksum().  It now works even though the s-file is
	mode 444 (which is what it should be).

	* file.cc: Eliminated compiler warning.

1998-11-13  James Youngman  <jay@gnu.org>

	* NEWS: Added changes for 0.09alpha.pl1.

	* configure.in: Bumped up the patchlevel.

	* docs/cssc.texi: Documented sccsdiff.

	* run.cc: Call errormsg_with_errno() correctly.

1998-11-12  James Youngman  <jay@gnu.org>

	* cdc.cc: Reformatted the error message that you get when trying to get
	arguments from stdin without also using the -y option.

1998-11-01  James Youngman  <jay@gnu.org>

	* docs/FIXED: Added fixes from Dick Streefland.

	* testutils/Makefile.am: Added the "yammer" program.

	* docs/Platforms: Also tested on Red Hat 5.1.

	* docs/CREDITS: Added credit to Greg Woods.

	* tests/binary/seeking.sh: Avoid requiring the "nl" utility.

	* testutils/yammer.c:
	This program is not installed as part of CSSC.  It's just used by
	the test suite.  It takes two arguments, the first being a repeat
	count, and the second being a string that should be repeated that
	many times.  For example, "yammer 2 blah" should emit
	  1 blah
	  2 blah

	The program was designed to eliminate the requirement to do
	  yes blah | nl | head -2
	because some systems, for example NetBSD/SPARC 1.3.2, lack the "nl"
	utility.

	* run.cc:
	When calling errormsg_with_errno(), actually pass errno as the first argument.

1998-10-29  James Youngman  <jay@gnu.org>

	* sccsfile.cc:
	Added toleration for some features that Larry is putting into
	BitKeeper.

	* auxfiles/Makefile.am: Added newline at the end of the file.

	* show-disp.sh:
	Don't use the --lint --posix for awk, because only GNU awk likes them.

1998-10-21  James Youngman  <jay@gnu.org>

	* file.cc:
	Use stat(2) rather than fstat(2), so that the file locking does indeed
	work over NFS.

1998-10-20  James Youngman  <jay@gnu.org>

	* auxfiles/Makefile.am:
	Ensure that CSSC.spec and CSSC.spec.in both get distributed.

	* tests/get/no-sfile.sh:
	Added no-sfile.sh, which tests for the existence of a bug pointed out
	by Dick Streefland <dick_streefland@tasking.com> (we core dump when we
	should exit with status 1, if no SCCS file is specified for some
	tools)

	* unget.cc, sf-prs.cc, sf-get2.cc, sact.cc, rmdel.cc, run.cc, prt.cc, prs.cc, get.cc, fileiter.cc, fileiter.h, delta.cc, cdc.cc, admin.cc:
	Patches from Dick Streefland <dick_streefland@tasking.com>:-
	> I'm sending you three patches for CSSC-0.09alpha.pl0. Patch #1 fixes
	> two prototype mismatches. Patch #2 makes sure that "get" and "prs"
	> return a proper exit status in the case of an output file error
	> (e.g.  disk full). Patch #3 fixes the problem that when you invoke
	> one of the tools without an SCCS file, it will abort with a core
	> dump. Abort() is called because an exception is raised that is not
	> handled. I removed the exception, and added explicit tests in each
	> tool.

1998-09-07  James Youngman  <jay@gnu.org>

	* file.h: Added fcreate() flag enum for atomic locking over NFS.

	* file.cc:
	Made the lockfile create more robustly atomic over NFS by using the
	lock-then-stat approach.  Fall back on using the regular open() with
	O_EXCL if it look slike the underlying filesystem does not support
	hard links.

1998-09-06  James Youngman  <jay@gnu.org>

	* sf-delta.cc, pf-del.cc, bodyio.cc:
	Use fcreate() to create files for writing, rather than fopen().
	This allows us to use open(.., O_CREAT|O_EXCL).

	* get.cc:
	If we fail to add the lock to the p-file, delete the gotten editable file.

	* docs/cssc.texi:
	Documented the various prefixes used for files, temporary and otherwise.

	* tests/get/writable.sh:
	Make sure "get -k" produces a writable g-file and "get" without -k
	does not.

	* tests/admin/i-option.sh, sf-write.cc, sf-delta.cc, sccsfile.h, sccsfile.cc, pf-del.cc, get.cc, pf-add.cc, file.cc, bodyio.cc, bodyio.h:
	Take special care to close and delete temporary files if an exception
	is thrown.

	* README: Typo.

1998-09-05  James Youngman  <jay@gnu.org>

	* configure.in:
	Generate auxfiles/CSSC.spec from auxfiles/CSSC.spec.in, to get the
	version number substituted.

	* auxfiles/CSSC.spec.in, auxfiles/CSSC.spec:
	Generate CSSC.spec from CSSC.spec.in, using substitution of @VERSION@.

1998-09-04  James Youngman  <jay@gnu.org>

	* NEWS: UPdated for 0.09alpha.pl0.

	* ChangeLog: Added in the changes for 0.09alpha.pl0.

	* README: Fixed typo.

1998-09-03  James Youngman  <jay@gnu.org>

	* except.h: Declarations of exceptions.

	* Makefile.am: Added except.h.

	* tests/prt/exists.sh:
	Added tests that check for correct behabiour when the s-file is
	absent.

	* sact.cc: Catch exceptions in main().

	* shorter/rmdel.cs, shorter/sact.cs, shorter/unget.cs, shorter/what.cs, shorter/README, shorter/admin.cs, shorter/cdc.cs, shorter/delta.cs, shorter/get.cs, shorter/prs.cs, shorter/Makefile.in:
	We have not been keeping these files up to date and haven't used
	them at all, and we planned not to have to use them.  So they're
	obsolete.

	* tests/get/create.sh:
	Make the test suite miscarry if the test files can not be created.

	* tests/initial/root.sh, tests/Makefile.am:
	Make sure we start the test suite by making sure that we're not
	running as root.

1998-09-02  James Youngman  <jay@gnu.org>

	* tests/common/not-root:
	If the code inside the subshell exits with a nonzero exit status, make
	sure that the "outer" shell does too -- so that the miscarry() takes
	effect.

	* tests/bsd-sccs/driver-basic.sh:
	Remove the SCCS directory too, when the test is finished.

	* sid_list.h, unget.cc, sf-write.cc, sf-prs.cc, sf-get2.cc, sf-kw.cc, sf-get.cc, sf-delta.cc, sf-admin.cc, sccsfile.h, sccsfile.cc, run.cc, quit.h, rel_list.cc, rmdel.cc, prt.cc, quit.cc, pf-add.cc, pfile.cc, prs.cc, filepos.h, get.cc, file.cc, fileiter.cc, delta.cc, configure.in, delta-table.cc, bodyio.cc, cdc.cc, acconfig.h, admin.cc:
	On systems that support exceptions, handle errors by throwing
	exceptions.  On systems that don't support exceptions, handle some
	errors by returning back up the calling sequence, and some by calling
	exit() in quit().  This means that only systems with exceptions will
	allow the second file to be processed if the first fails.

	* docs/cssc.texi:
	"admin -h" is actually unimplemented, rather than just untested.

	* tests/rmdel/exists.sh, tests/unget/exists.sh, tests/prs/exists.sh, tests/prs/keywords.sh:
	Added tests that check for correct behaviour when the s-file does
	not exist.

1998-08-22  James Youngman  <jay@gnu.org>

	* sf-write.cc: Eliminate unused-parameter warning.

1998-08-15  James Youngman  <jay@gnu.org>

	* docs/TODO: We now use getpwuid() instead of getlogin().

1998-08-14  James Youngman  <jay@gnu.org>

	* unget.cc, sf-write.cc, sid_list.h, sf-prs.cc, sf-get3.cc, sf-kw.cc, sf-get2.cc, sf-get.cc, sf-delta.cc, sccsfile.h, rel_list.cc, fileiter.cc, filepos.h, get.cc, file.cc, file.h, delta.cc, admin.cc:
	Use errormsg() or errormsg_with_errno() more, instead of quit().

1998-08-13  James Youngman  <jay@gnu.org>

	* auxfiles/CSSC.spec, configure.in: Bumped to 0.09alpha.pl0.

	* README: Indicate how to generate all the neccesary files after a "cvs
	checkout".

	* bodyio.h, bodyio.cc, sf-delta.cc, sf-admin.cc:
	Handle I/O errors without calling quit().

	* sf-get2.cc:
	Added reminder to check if we handle the %W% keyword correctly.

	* sf-get.cc, l-split.cc, delta.cc:
	Cosmetic changes to the code formatting.

	* sf-prt.cc:
	Use errormsg_with_errno(), not quit(), and return a failure status
	intead of exiting on the spot when there is a problem (so that we can
	continue to process the next file).

	* sf-prs.cc: Cosmetic changes to the code formatting.

	* pfile.cc:
	Added ctor_quit(), a synonym for quit(), which indicates that it is
	being called from a constructor.  These are the failure points that
	can't be replaced with a "return false", but only with an exception.

	* fileiter.cc: Cosmetic changes to the code formatting.

	* cssc.h: Don't need to worry about getlogin() any more.

	* unget.cc: Return a failure status if pfile.update() had failed.

	* sid.cc:
	Use assert(), not quit(), to detect logic errors in the program.

	* sf-write.cc, sf-delta.cc:
	Use errormsg_with_errno(), not quit(), and return a failure status
	intead of exiting on the spot when there is a problem (so that we can
	continue to process the next file).

	* sccsfile.cc:
	Use errormsg_with_errno(), not quit(), and return a failure status
	intead of exiting on the spot when there is a problem (so that we can
	continue to process the next file).

	Added ctor_quit(), a synonym for quit(), which indicates that it is
	being called from a constructor.  These are the failure points that
	can't be replaced with a "return false", but only with an exception.

	* quit.h, quit.cc:
	Added ctor_quit(), a synonym for quit(), which indicates that it is
	being called from a constructor.  These are the failure points that
	can't be replaced with a "return false", but only with an exception.

	* pf-del.cc:
	Use errormsg_with_errno(), not quit(), and return a failure status
	intead of exiting on the spot when there is a problem (so that we can
	continue to process the next file).

	* file.cc: Use getpwuid(), not getlogin(), for get_user_name().

1998-08-12  James Youngman  <jay@gnu.org>

	* pfile.h: Make update() return a boolean indication of success.

1998-06-19  James Youngman  <jay@gnu.org>

	* NEWS, ChangeLog:
	Normal prerelease modifications to ChangeLog, NEWS, etc.

	* configure.in, auxfiles/CSSC.spec: Bumped the patchlevel.

	* mystring.cc:
	re-fixed bug in find_last_of().    First bugfix had a bug.

	* bsd/sccs.c:
	Use our own error code definitions taken from the glibc <sysexits.h>.
	This is to avoid a compiler error due to the redifinition on Solaris
	(with GCC installed).

	* bsd/sccs.1: Documented the various possible error codes.

1998-06-16  James Youngman  <jay@gnu.org>

	* configure.in: Bumped version to 0.08alpha-pl0.

	* ChangeLog: *** empty log message ***

	* auxfiles/CSSC.spec: Changed version to 0.08alpha-pl0.

	* docs/FIXED: Added a report of the mystring::find_last_of() bug.

	* docs/CREDITS: Added apology to Achim Hoffmann.

	* docs/style.txt:
	"f()" vs. "f ()": added plea for any reason to prefer one over the
	other.

	* docs/cssc.texi:
	Indicate that the fatal-exit-on-error problem is being worked on.

	* NEWS: *** empty log message ***

	* docs/cssc.texi:
	Added a short remark about Emacs's VC-mode in the section on delta; if
	an SCCS file has the V flag set, you need to put an -m option in
	vc-checkin-flags in order to be able to check in revisions within
	Emacs.

	* sccsfile.cc:
	Oops.  Include <ctype.h> if STDC_HEADERS is defined, because
	HAVE_CTYPE_H is not defined by our configure.in.

	* mystring.cc:
	Fixed find_last_of().  We were finding the FIRST occurrence of the
	target rather than the last.  Argh!  How stupid is that?

	* tests/prs/keywords.sh: Make sure prs accepts an empty "-r" option.

1998-06-15  James Youngman  <jay@gnu.org>

	* fileiter.cc:
	When reading a list of filenames from stdin, trim off the newline that
	separates the filenames.

	* sf-write.cc, sf-prs.cc, sf-prt.cc, sf-rmdel.cc, sf-get.cc,
	sf-get2.cc, sf-cdc.cc, sf-delta.cc, sccsfile.h, sf-add.cc,
	sf-admin.cc, quit.cc, quit.h, rmdel.cc, file.cc, get.cc, prt.cc,
	cdc.cc, delta.cc, admin.cc:
	Don't use quit(); rather, use errormsg() and make a fatal exit
	from the function which we are now executing.  When this
	propagates up to the top level, remember the error so we cal later
	exit with a return value of 1, but nevertheless continue to
	process command-line arguments.

	* prs.cc:
	Allow the -r option to have no argument, without producing an error.
	When processing SCCS files, allow any of them to fail without this
	causing the whole operation to abort, but remember the fact and exit
	with a return value of 1 (hence use errormsg() rather than quit() for
	producing error messages).

1998-06-14  James Youngman  <jay@gnu.org>

	* unused/Makefile.am, unused/README, quit.cc, configure.in,
	Makefile.am:
	Moved some files into the "unused" directory, which we now add into
	the distribution.   They may be useful for ports or something.

	* unused/sid_list.cc, unused/pipe.cc, unused/pipe.h,
	unused/ffsync.cc, unused/fsync.cc, unused/move-if-change,
	unused/dosfile.cc, unused/dummy.cc, unused/_chmod.cc, dosfile.cc,
	ffsync.cc, move-if-change, pipe.cc, pipe.h, sid_list.cc,
	_chmod.cc, dummy.cc, fsync.cc: 
	Moved some files into the "unused" directory; we don't use them
	any more and keeping them aroung means that they have to be
	considered during global search and replace operations.  That's
	just making more work for myself.  These files are the contents of
	the $(rainyday_src) macro in the makefile.

	* unget.cc, sccsfile.cc, sact.cc, rmdel.cc, run.cc, quit.cc,
	quit.h, prt.cc, pipe.cc, prs.cc, pf-add.cc, pfile.h, get.cc,
	file.cc, delta.cc, admin.cc, cdc.cc:
	Changes to avoid using quit(); rather, we want to emit an error
	message and return an error status to the caller.  This allows an
	SCCS program to process a list of files without quitting
	prematurely because there was somethign wrong with some file early
	in the list.  More changes remain to be done for this to be
	complete.

	* Makefile.am: Added dosfile.cc and ffsync.cc.

	* dosfile.cc, ffsync.cc:
	Moved some system-dependent code out of file.cc.

	* delta.cc:
	Use errormsg() rather than quit() so that if the first file fails, the
	second may still be processed.

1998-06-13  James Youngman  <jay@gnu.org>

	* README:
	Added some basic remarks about configuuring the destination directory
	to the "QuickStart" section of the file.  Also, change the sample test
	script to send the version information too.

	* fdclosed.cc:
	Fixed copyright date and removed extraneous #include of err_no.h.

	* fdclosed.cc: Fixed the comments.

	* Makefile.am, fdclosed.cc:
	Provide a static object constructor that ensures that file descriptors
	0, 1 and 2 are not closed at the start.  Otherwise we might printf()
	to stdout and accidentally modify a file we fopened() for writing.

	* bsd/Makefile.am: Define PREFIX to be $(csscutildir) by default.

1998-06-11  James Youngman  <jay@gnu.org>

	* ChangeLog, NEWS: Final additions for 0.07alpha.pl3.

	* bsd/Makefile.am:
	Even though sccs.1 is in man_MANS, we still need to get it added to
	EXTRA_DIST in order to get it in the distribution.   Argh.

1998-06-10  James Youngman  <jay@gnu.org>

	* configure.in: Bumped the patchlevel.

	* auxfiles/CSSC.spec:
	Fixe dchangelog, added sccs manpage, included all the info files.

	* NEWS, ChangeLog: Added changes for CSSC-0.07alpha-pl3.

	* bsd/Makefile.am:
	Added COPYNG.bsd to the distribution.   Also .ispell_english.
	Added the manual page sccs.1 too.

	* tests/common/test-common, tests/common/not-root,
	tests/bsd-sccs/driver-basic.sh: Ensure the test suite is not run
	by root (because that makes "test -w" return misleading results).

1998-06-09  James Youngman  <jay@gnu.org>

	* auxfiles/CSSC.spec, docs/CREDITS, NEWS, configure.in:
	Bumped to CSSC-0.07alpha-pl2

	* sccsfile.cc:
	Fixes to tolerate spurious arguments on ^AU and ^At lines.
	This problem reported by Marko Rauhamaa <marko@tekelec.com>.

1998-06-08  James Youngman  <jay@gnu.org>

	* NEWS, ChangeLog: Summarised changes for 0.07alpha-pl1.

	* auxfiles/CSSC.spec, configure.in: Bumped to 0.07 patchlevel 1.

	* prompt.cc: Allow newlines to be escaped with a backslash.

	* sf-get.cc:
	Don't warn about keyword substitution not being done for binary files;
	I don't think it should be done in any case.

	* tests/admin/abspath.sh:
	Use a less complicated way of building the command.   We seem to have
	a small problem with this:-  anthonyc@nag.co.uk sees
	"/zome/anthonyc/.../s.bar: no such file or directory".
	  ^ Note that the z for the lockfile name appears here!

	* tests/prt/reportmr.sh:
	Some shells don't like two assignments on one line, for example
	"g=reportmr.1 s=inputs/s.$g".  With these shells, the $g in the second
	assignment expands to nothing.  "ash" version 0.2 is like this. Bash
	version 1.14.7 is not.

	* bsd/sccs.c: Support "sccs cdc".

	If we use "sccs create -b foo", pass the "-b" flag to "admin", but not
	to "get".  Passing it to "get" would mean "create a branch" rather
	than "binary" and we're not checking the file out for editing anyway.
	This at the request of <peter.kjellerstedt@axis.com>.

1998-06-06  James Youngman  <jay@gnu.org>

	* bsd/sccs.c:
	Be as careful about running setgid as we are about running setuid.

	* bsd/sccs.c:
	Insist on the compile-time macro SCCSDIR having been set if the program
	is installed set-user-id (what about set-group-id?).

	* tests/bsd-sccs/driver-basic.sh:
	Unset $LANG so that the tests for sccs(1) don't fail on systems
	which are mosconfigured, just because they are misconfigured.

	* docs/TODO: *** empty log message ***

	* NEWS: Added update for version 0.07alpha-pl0.

	* ChangeLog: Updated for version 0.07alpha-pl0.

	* configure.in: Bumped to version 0.07.

	* auxfiles/CSSC.spec: *** empty log message ***

	* tests/common/command-names:
	Set ${sccs} here in tests/bsd-driver/*, and not this file.  We keep it
	out of command-names since we currently need to run sccs in order to
	decide if we need to pass it the --prefix option.  That would slow all
	the other tests down.

	* tests/bsd-sccs/driver-basic.sh:
	Set ${sccs} here in this file.  We keep it out of common/command-names
	since we currently need to run sccs in order to decide if we need to
	pass it the --prefix option.  That would slow all the other tests
	down.

	* tests/prt/nodel.sh, tests/prt/default.sh:
	Remove s.testfile when the test is complete.

	* bsd/sccs.c, bsd/sccs.1:
	Modified to work with portability hints provided by Automake
	(e.g. sys_siglist[], struct dirent vs. struct direct, and so on); also
	other portability enhancements.

	Modifued some of the string handling for greater protection against
	buffer-overflow.

	Added extra options to sccs (--cssc, --prefix) to allow the
	program to be tested before the sub-programs (edmin, get, etc.)
	are installed in their final positions.  Added --version and -V
	options (which do the same thing).

	Documented this in the manpage; also added a COPYING section and
	added some more entries in the SEE ALSO section.

	Folded pathnames.h into sccs.c.

	* bsd/Makefile.am: Rolled pathnames.h into sccs.c.

	* bsd/.ispell_english: Removed entries containing punctuation or
	digits; ispell doesn't like them.

	* bsd/pathnames.h: Rolled the few remaining definitions into sccs.c

	* bsd/pathnames.h:
	Don't use absolute paths for the locations of the subcommands.

1998-05-30  James Youngman  <jay@gnu.org>

	* tests/bsd-sccs/driver-basic.sh: Added tests for "sccs check".

	* tests/bsd-sccs/driver-basic.sh:
	Added tests for deledit, delget, fix, tell, rmdel, what, enter, edit,
	clean, unedit and info.

	* configure.in, acconfig.h:
	Detect sys_suglist, for bsd/sccs.  Also detect <locale.h>.  Bump
	patchlevel to 9 (though we may end up making a new release instead).

	* sccsfile.cc:
	find_any_delta(sid id): will find even removed deltas.  This is part
	of the "sccs fix" bugfix.

	* tests/common/command-names:
	Oops.  Set sccs=sccs as a last resort if we can't find it.

	* delta-table.cc, sf-get2.cc, sccsfile.h, delta-table.h:
	When getting a delta for editing, and the trunk successor has been
	rmdel'ed, reuse it (this is required for "sccs fix" to work properly,
	and it's the way real-sccs works).

	* tests/rmdel/edit.sh:
	Tests that do "delta" after an "rmdel" to make sure the right things
	happen.

1998-05-28  James Youngman  <jay@gnu.org>

	* bsd/sccs.c:
	Cope in a more portable way with the status return from a child.

	* bsd/sccs.c: Allow "sccs -V -V -V" without generating a coredump.

	* bsd/sccs.c:
	Some portability improvements; don't need sig_t; cope without
	sys_siglist if we don't have it.   This mostly affects Linux with libc
	version 5 and below, I think.

1998-05-27  James Youngman  <jay@gnu.org>

	* bsd/sccs.c, bsd/.ispell_english, bsd/pathnames.h:
	Some range chacking corrections, correctiosn to the PREFIX macro, etc.

	* bsd/COPYING.bsd:
	Explained why part of CSSC is published under the BSD license

	* docs/TODO:
	Added note about considering the use of getpwuid() in preference to getlogin().
	Removed TODO entries from some stuff that's been done.

	* README:
	We now support binary files; remove the statement that we do not...

	* what.cc, sccsfile.cc, bodyio.cc, cssc.h:
	Removed some unused configuration macros.
	Renamed CONFIG_BINARY_FILE to CONFIG_OPEN_SCCS_FILES_IN_BINARY_MODE.

	* scripts/change-suffix, unused/change-suffix:
	change-suffix should be in scripts, not unused :-)

	* unused/change-suffix: Moved change-suffix into "unused".

	* change-suffix: Moved change-suffix unti "unused".

	* tests/bsd-sccs/driver-basic.sh, tests/Makefile.am:
	Added tests for the driver program "sccs".

	* tests/common/test-common: Use ../../testutils/ekko as a fallback.

	* tests/common/command-names: Added entry for the "sccs" command.

1998-05-25  James Youngman  <jay@gnu.org>

	* defaults.h: Removed some unused features.

	* docs/CREDITS:
	Added info about the BSD-derived code (sccs.c and friends).

	* AUTHORS: Added info about the BSD-derived code (sccs.c and firends).

	* docs/cssc.texi:
	Added documentation about sccs.c, the BSD copyright notice, and added
	some more concept index entries.

1998-05-23  James Youngman  <jay@gnu.org>

	* bsd/sccs.c:
	Some attempts at increased security and portability.  No tests for
	this program yet though, so no certainty that this works.

1998-05-12  James Youngman  <jay@gnu.org>

	* tests/prt/inputs/s.reportmr.1:
	Oops.  I'd been working with a different file in the compilation
	directory.

	* ChangeLog: *** empty log message ***

	* configure.in: Moved to 0.06alpha.pl8

	* NEWS: Additions for 0.06pl8.

1998-05-11  James Youngman  <jay@gnu.org>

	* testutils/README: Fixed typo.

	* tests/prt/inputs/s.reportmr.1, tests/prt/reportmr.sh:
	New tests for those cases where there are MRs to be reported.

	* sf-prt.cc, prt.cc:
	Make sure the MR list (etc.) is formatted correctly when we are
	printing one delta per line.

1998-05-10  James Youngman  <jay@gnu.org>

	* bodyio.cc:
	Don't store the result of getc() in a char, use an int -- that way, we
	can detect EOF.

	* sf-write.cc:
	Remove comment discussing broken behaviour with "admin -i" and
	nonseekable binary standard input that has now been fixed.

	* testutils/lndir.c: Ignore CVS directories too.

1998-05-09  James Youngman  <jay@gnu.org>

	* sf-rmdel.cc, sid.cc, sccs-delta.cc, sccsname.cc, prs.cc,
	quit.cc, pipe.cc, fsync.cc, pf-add.cc, file.cc, fileiter.cc,
	delta.cc, cdc.cc, delta-table.cc: 
	Get the name of the file right, in each file's comment header.

	* sf-write.cc, sccsfile.h:
	Fixed some compilation errors; warnings about passing "unsigned *pSum" when "int *pSum" is required.

	* docs/Platforms, docs/CREDITS, docs/FIXED, docs/BUGS:
	Updated lists of outstanding anb fixed bugs, added people to CREDITS,
	and did some housekeeping in Platforms.

	* docs/cssc.texi:
	Added clarification that the file that must be specified on the
	"delta" command line is that of the s-file, not the working file.

1998-05-08  James Youngman  <jay@gnu.org>

	* CSSC-0.06alpha.pl7 released.
	
	* NEWS, configure.in, ChangeLog: Released 0.06alpha.pl7.

	* docs/cssc.texi: Added header for install-info.

	* auxfiles/CSSC.spec:
	Included mods from John Interrante <interran@crd.ge.com>,
	except his patch to pathname.h; must apply that RSN.

	* sf-delta.cc, seqstate.cc, seqstate.h, sccsfile.cc,
	delta-iterator.h, Makefile.am: Fixed bug in seqstate.h that
	manifested with Codemgr SCCS files.  This required the
	introduction of seqstate.cc and a modification to sf-delta.cc as
	well.

1998-05-06  James Youngman  <jay@gnu.org>

	* seqstate.h:
	Reindented to prepare for new code which maintaind the state of the
	"deleting" flag differently.

1998-05-05  James Youngman  <jay@gnu.org>

	* CSSC-0.06alpha.pl6 released.
	
	* NEWS: Added entry about "sccs.c".

1998-05-04  James Youngman  <jay@gnu.org>

	* bsd/sccs.c, bsd/pathnames.h, Makefile.am:
	Attempted to make the location of "sccs" configurable.   Also attempted to add const modifiers where useful.

	* NEWS: Added "-t" option.

	* sccsfile.cc:
	Use signed arithmetic for checksums.    I *think* that matches the
	"real" SCCS.  Also produce what I hope are more useful messages when
	the checksum is incorrect (or even the checksum header is missing).

	* sccsfile.h:
	Use signed arithmetic for checksums.    I *think* that matches the
	"real" SCCS.

	* configure.in: Added the "bsd" directory.

	* tests/get/branch.sh:
	Added note about the SCO version of "unget" being silent.

	* docs/cssc.texi:
	texi2html doesn't expand homegrown macros, so we have to write the
	maintainer's email address out by hand in each place.

	* docs/Platforms: Added note for IRIX.

	* sid.h: Removed a #pragma -- they're not portable anyway.

	* pipe.h: Use "class foo : public bar {}" not "class foo : bar { }".

	* pfile.h: Removed a #pragma -- they're not portable anyway.

	* mystring.h:
	Added comment about functions disalbigiated only by the constness of
	*this.   Some versions of the IRIX C++ compiler don't like that (error
	3392).

	* linebuf.h: Actually remove a #pragma that had been commented out.

	* filelock.h: Explicitly use "private" in inheritance spec
	(e.g. 'class foo : private bar {}') ,
	we can't just leave it out.

	* fileiter.cc:
	If an argument is a directory which is named so as to end in a slash,
	don't coredump.

1998-03-18  James Youngman  <jay@gnu.org>

	* bsd/sccs.c: Reindented with GNU Indent.

	* bsd/sccs.c: Many const-correctness changes.

1998-03-17  James Youngman  <jay@gnu.org>

	* bsd/Makefile.am, bsd/Makefile.bsd, bsd/COPYING.bsd, bsd/Makefile:
	Updated the copyright info.  There is a different copyright situation
	locally in this dir.

	* bsd/sccs.c:
	Eliminated many compiler warnings.  Partial Autoconf conversion.

	* bsd/sccs.c: Use stdarg.h instead of old-style /*VARARGS1*/ etc.

1998-03-16  James Youngman  <jay@gnu.org>

	* bsd/sccs.me, bsd/sccs.c, bsd/pathnames.h, bsd/sccs.1, bsd/Makefile:
	Added files from the Berkeley sccs.c implementation.

1998-03-15  James Youngman  <jay@gnu.org>

	* tests/get/t-option.sh, docs/style.txt, docs/get-spec.txt, docs/cssc.texi, docs/Makefile.am, docs/TODO, sf-get2.cc, get.cc, Makefile.am:
	Implemented the "-t" option of get.

	* tests/get/t-option.sh: Tests for the -t option of get.

1998-03-14  James Youngman  <jay@gnu.org>

	* sccsdate.cc, sccsfile.cc, sf-get.cc, configure.in, file.cc, filediff.cc, admin.cc, bodyio.cc:
	Fixed some compiler warnings, no change in functionality.

	* docs/Makefile.am: Added mailing-list.txt.

	* docs/mailing-list.txt:
	Information about the mailing list for GNU CSSC.

	* docs/patches.txt:
	Requested that people specify the purpose of the submitted patch, and
	delete all editor backup files before generating it.

	* testutils/lndir.c, testutils/ekko.c:
	Eliminate some compiler warnings; falling off the end of int-returning
	functions and that sort of thing.

	* testutils/seeker.c:
	setlinebuf() is not a standard ISO-C library function and SCO Unix
	(for example) does not provide it.  It has an exact setvbuf()
	equivalent, so use that instead.

1998-03-11  James Youngman  <jay@gnu.org>

	* auxfiles/Makefile.am, Makefile.am, configure.in:
	Added the "auxfiles" directory so that CSSC.spec is distributed.

	* ChangeLog, NEWS: Detailed the updates for CSSC-0.06alpha-pl5.

	* auxfiles/CSSC.spec, configure.in: Bumped patchlevel to 5.

	* docs/FIXED, docs/BUGS: Oops.  Left a fixed bug in eocs/BUGS --
	and the patchlevel number for the first fixed version was wrong.
	All better now.

	* tests/rmdel/basic.sh:
	Make sure that the revision we tried to remove is actually now absent.

	* tests/common/command-names, tests/rmdel/basic.sh, docs/BUGS,
	docs/CREDITS, docs/Platforms, tests/Makefile.am, sf-rmdel.cc:
	Fixed bug in "rmdel" reported by Peter Kjellerstedt.  "rmdel" had
	been deleting all the control lines.

1998-03-10  James Youngman  <jay@gnu.org>

	* docs/FIXED, auxfiles/CSSC.spec, NEWS, configure.in, ChangeLog:
	Miscellaneous updates for 0.06-pl4.

	* tests/Makefile.am:
	Don't export CVS directories into the distribution.

	* admin.cc:
	Absolute pathnames now work; bug reported by Wolfhard Straehle.

	* tests/admin/abspath.sh:
	Test for bug reported by Wolfhard Str\"ahle; admin -n /abs/path/s.foo
	fails because the "admin" code checks for an "s." after the first
	slash when in fact it should check for an "s." after the LAST one.

1998-03-10  James Youngman  <jay@gnu.org>

	* get.cc:
	Fixes from Peter Kjellerstedt.  First, correct output when a direcory
	is specified on the command line (get should always print the name of
	the current s-file).  Second, when multiple files are specified on the
	command line, don't corrupt the requested SID value by updating it
	with an actual SID value from some particular s-file.

	* sccsdiff.sh.in: Support for filenames containing spaces.

	* filediff.cc, filediff.h, sf-delta.cc:
	Better support for files whose names have spaces in them.

1998-03-09  James Youngman  <jay@gnu.org>

	* filediff.h, filediff.cc:
	finish() returns a bool; false if the child process returned nonzero.

	* sf-delta.cc, fileiter.cc:
	Make FileDiff::finish() return a bool; it returns false if pclose()
	indicates that the spawned process returned a nonzero exit status.
	[ REVERSED -- this was a BAD idea, diff returns 1 if the 
	  files differ! ]
	
	* sccsdiff.sh.in:
	Bug report from Richard Polton: IRIX's pr(1) requires a space between
	the "-h" and its argument.

1998-03-04  James Youngman  <jay@gnu.org>

	* tests/common/real-thing: Define TESTING_CSSC if $dir points at
	CSSC programs rather than SCCS programs.

	* tests/binary/auto.sh: Use $TESTING_CSSC to determine of we
	should run those tests that CSSC should pass but (some verisions
	of) SCCS cannot, instead of abusing $expect_fail.

	* docs/BUGS, docs/FIXED: Some entries moved from BUGS to FIXED.

1998-03-01  James Youngman  <jay@gnu.org>

	* Version 0.06alpha-pl3

	* auxfiles/CSSC.spec: 0.06alpha-pl3

	* configure.in, ChangeLog, NEWS:
	Updated the NEWS and ChangeLog files (0.06alpha-pl3)

	* tests/binary/auto.sh, tests/binary/seeking.sh:
	Tests for binary files and the "-i" option of admin.

	* docs/cssc.texi:
	Genuine SCCS doesn't always properly recover from finding out that
	the "-i" file for admin needs encoding, after having read some of it.

	* bodyio.cc, admin.cc:
	When generating a new SCCS file using the "-i" option of admin,
	we no longer need to be able to seek on that file if the input
	turns out to need encoding after we have read some of it.

	* tests/admin/i-option.sh: We no longer do fgetpos() on stdin.

1998-02-28  James Youngman  <jay@gnu.org>

	* xalloc.cc, xalloc.h, Makefile.am:
	Removed xalloc.cc and xalloc.h completely.

	* show-disp.sh:
	Cope correctly with locally removed files when the actual working file
	has been deleted.

	* docs/CREDITS, xalloc.cc, sl-merge.h, stack.h, sid_list.cc,
	sid_list.h, sid.cc, run.cc, seqstate.h, pipe.cc, linebuf.cc,
	linebuf.h, delta-table.cc, l-split.cc, cssc.h: Patches from
	Richard Polton to eliminate our xalloc.h wrapper for operator new,
	as various versions of GCC differ on the exception throwing
	specification -- if we don't have to override the operator new, we
	don't have to get the declaration right :-)

	* admin.cc:
	Turn off buffering on stdin, as a workaround for a bug in glibc 2.0.6.

	* tests/common/test-common: success(): Delete temporary files.

	* tests/admin/i-option.sh, tests/admin/t-option.sh:
	Temporarily mark the "admin -i" tests "expect-fail".

1998-02-24  James Youngman  <jay@gnu.org>

	* auxfiles/CSSC.spec: Updated the version.

	* tests/binary/char255.uue:
	This file contains one character (uuencoded), the ASCII code 255.

1998-02-23  James Youngman  <jay@gnu.org>

	* configure.in: Bumped version to 0.06alpha.pl2

	* ChangeLog.1, ChangeLog: *** empty log message ***

	* tests/binary/eightbit.sh, tests/binary/diff.sh, tests/Makefile.am:
	Run the binary-file tests as part of "make check".  Small fixes to
	those tests.

	* tests/binary/eightbit.sh, bodyio.cc, NEWS:
	Fixes to allow the character whose code is 255 to be properly handled.

	* tests/binary/eightbit.sh: Tests involving 8-bit bodies.

	* tests/binary/s.umsp.uue: SCCS file containing 8-bit characters.

	* docs/BUGS, docs/FIXED, sf-write.cc, sccsfile.cc: Checksum is now
	8-bit-clean, due to richardp@scopic.com and
	Peter.Kjellerstedt@axis.com.

	* testutils/Makefile.am:
	Added seeker.c, which tests for a particular bug in GNU libc 2.0.6.

	* unget.cc, what.cc, rmdel.cc, sact.cc, prt.cc, my-getopt.h,
	prs.cc, get.cc, my-getopt.cc, fileiter.h, delta.cc, fileiter.cc,
	admin.cc, cdc.cc: Renamed class getopt to class CSSC_Options, to
	avoid conflict with getopt(3) on systems such as netbsd-1.2 (as
	installed on melange.gnu.org)

	* testutils/seeker.c:
	Test program which determines if fgetpos() works correctly on stdin.

1998-02-21  James Youngman  <jay@gnu.org>

	* auxfiles/CSSC.spec: Corrected source file name.

	* auxfiles/CSSC.spec: Strip the installed binaries.

	* NEWS: Updated for CSSC-0.06devel-pl1.

	* ChangeLog: *** empty log message ***

	* what.cc, sid_list.cc, unget.cc, sf-prt.cc, sf-prs.cc,
	sf-get2.cc, sf-kw.cc, sf-get.cc, sf-chkid.cc, sf-delta.cc,

	fileiter.h, filepos.h, file.cc, delta.cc, encoding.cc, cssc.h,
	defaults.h, bodyio.h, cdc.cc, bodyio.cc: Updated the year in the
	copyright message for all those files modified so far in 1998.

	* docs/FIXED, docs/TODO, docs/BUGS: Added some bug reports.

	* unget.cc, sact.cc, sf-get.cc, rmdel.cc, prs.cc, prt.cc, my-getopt.cc, my-getopt.h, fileiter.h, get.cc, fileiter.cc, cdc.cc, delta.cc, admin.cc:
	Modified option processing so that "get s.foo -Gbaz" is equivalent
	to "get -Gbaz s.foo".

	* configure.in: Bumped version to 0.06-pl1.

	* docs/cssc.texi: Minor punctuation corrections.

	* tests/prs/keywords.sh: Added test for :PN:.

	* Makefile.am, sf-prs.cc:
	The prs keyword :PN: needs to produce the full pathname of the SCCS
	file, not just the name as specified on the command line.

	* tests/get/optorder.sh: Initial version.

1998-02-20  James Youngman  <jay@gnu.org>

	* sf-write.cc:
	Cope in a more user-friendly way with the prior existence of "x.foo".

	* docs/BUGS:
	Some bug reports from Peter Kjellerstedt <peter.Kjellerstedt@axis.com>
	and Dave Bodenstab <imdave@mcs.net>.

	* tests/get/sep_subst.sh:
	Make sure the substitution happens for the actual gotten delta, not
	the delta to which the current line belongs.

	* tests/get/sep_subst.sh: *** empty log message ***

	* tests/get/sep_subst.sh:
	Make sure that the delta information substituted for each line is the
	information for the delta that we are actually getting, not the delta
	information for the delta which last touched that line.

1998-02-12  James Youngman  <jay@gnu.org>

	* ChangeLog: *** empty log message ***

	* auxfiles/CSSC.spec: Updated RPM spec-file for version 0.06alpha.pl0.

	* ChangeLog: *** empty log message ***

	* docs/cssc.texi, docs/Platforms, docs/TODO, auxfiles/CSSC.spec, sf-write.cc, configure.in, sccsfile.cc, NEWS:
	Binary file support.

	* docs/missing.txt: Binary file support is now present.

	* tests/binary/binbasic.sh, filediff.h, sf-delta.cc, filediff.cc, Makefile.am, configure.in:
	First working binary file support.

1998-02-11  James Youngman  <jay@gnu.org>

	* tests/binary/auto.sh:
	Tests that ensure that admin correctly guesses if the original file is
	binary or not.

	* configure.in: Updated the patchlevel.

	* ChangeLog: *** empty log message ***

	* NEWS: Added the latest news.

	* docs/TODO, docs/BUGS, docs/FIXED:
	Updated the lists of bugs fixed, bugs discovered, and things to investigate.

	* pipe.h, pipe.cc:
	Some tidying.  This code seems problematic for binary files.  Some of
	the commented-out tests in tests/binary/binbasic.sh break it.

	* tests/get/create.sh: Corrected a comment.

	* tests/Makefile.am: Added testing fr binary files.

	* testutils/Makefile.am:
	Added "ekko", a substitute echo(1) for systems where the normal
	echo(1) does not support newline suppression and escape codes.

	* encoding.cc, bodyio.cc: Added support for deltaing encoded files.

	* auxfiles/CSSC.spec: Added the spec-file for RPM.

	* tests/delta/basic.sh:
	Make sure diff returns 0 for identical files and 1 for different ones.

	* bodyio.h, sf-kw.cc, linebuf.cc, sf-delta.cc:
	Support for deltaing encoded files.  We have a problem with the Pipe
	class and large input files (broken pipe) though.

	* file.cc, configure.in:
	Use stat() to detect if the g-file is writable, because if we are
	root, access() tells us yes even if the file is read-only.  This makes
	"get" fail, saying that a wrtable gfile exists.  Using stat() fixes
	this.

1998-02-10  James Youngman  <jay@gnu.org>

	* tests/common/test-common:
	Use testutils/ekko if no suitable echo(1) command exitst on the system
	(we need newline suppression and escape codes).

	* testutils/ekko.c:
	An echo(1) replacement for systems whose echo does not support escape
	codes and newline supression.

	* tests/binary/diff.sh, tests/binary/binbasic.sh:
	New tests for binary file support (get/delta etc).

	* docs/cssc.texi:
	Removed remarks about option processing, since we now do this the SCCS
	way.  Also, added remarks about the non-security of CSSC and advice not to install it setuid-root or use it as root.

1998-02-09  James Youngman  <jay@gnu.org>

	* sccsdiff.sh.in:
	Patch from Maurice O'Donnell <mod@tfn.com>: pass "-e" to sed before
	the sed commands.

	* tests/large/admin.sh, testutils/yes.c, testutils/Makefile.am:
	Solaris has no yes(1) utility so we roll our own.

1998-02-01  James Youngman  <jay@gnu.org>

	* bodyio.h: Prototypes for functions in bodyio.cc.

	* bodyio.cc:
	New file; functions for handling the I/O for the body of files
	(i.e. the bits that might be uuencoded).

	* ChangeLog, docs/TODO: *** empty log message ***

	* scripts/rev-freq.sh:
	Added rev-freq.sh, which generates a histogram of the distributon of
	CVS revision numbers.

	* config.h.in:
	This file is automatically generated by "autoheader".  We should not therefore keep it under CVS control, I think.

	* sccsfile.cc, pfile.cc:
	Added TODO comment for the places where we modify the contents of a
	cssc_linebuf nefariously.

	* Makefile.am:
	Added bodyio.cc and encoding.cc to those modules that now need it.

	* sf-get.cc:
	Added a no_decide flag to sccs_file::get() for the use of delta.  We
	need to be able to obtain the body in encoded form so that we can feed
	it to diff(1).

	* sf-delta.cc:
	cssc_linefuf now has its own check_id_keywords() member, as a
	preparatory step to 8-bit-cleanness.

	* sf-admin.cc:
	If body_insert() informs us that the body turned out to be binary, set
	flags.encoded so that sccs_file::end_update() can call
	rehack_encoded_flag() (in sf-write.cc).

	* sccsfile.h:
	Allow sccs_file::get() to be told not to uudecode an encoded file.  We
	do this in order to obtain the still-encoded text in otder for delta
	to feed it to diff.

	* linebuf.h, linebuf.cc:
	Changes for the beginnings of 8-bit-clean support.  We're not
	8-bit-clean yet though.  The class interface currently precludes it.

	* ioerr.h: Added fwrite_failed().

	* cssc.h, defaults.h:
	CONFIG_LINEBUF_CHUNK_SIZE is only used by linebuf.cc and only really
	needs ever to be changed as a tuning issue, so we #define it in
	linebuf.cc.  For the moment, we keep it low as this ensures that we
	debug the reallocation code.

	* configure.in:
	sf-chkid.cc can use memchr() if available, so detect it.

	* sf-chkid.cc: Rewrote check_id_keywords() for 8-bit-cleanness.

1998-01-25  James Youngman  <jay@gnu.org>

	* testutils/README, testutils/last-time.c, testutils/Makefile.am:
	Added last-time.c to the distribution.

	* tests/get/defsid.sh, tests/get/subst.sh: *** empty log message ***

	* tests/admin/flags.sh: Added checks for the default delta flag.

	* docs/TODO, docs/missing.txt, docs/FIXED: *** empty log message ***

	* sf-write.cc, sf-prs.cc, sf-prt.cc, sf-get2.cc, sf-admin.cc,
	sf-get.cc, sccsfile.h, sccsfile.cc, filepos.h, get.cc,
	encoding.cc, cssc.h, defaults.h, README, admin.cc, Makefile.am,
	NEWS, ChangeLog: Preliminary support for binary files; creation
	(initialisation) only.

1998-01-24  James Youngman  <jay@gnu.org>

	* docs/BUGS:
	Removed a bug report (by jay@gnu.org, me) that actually wasn't a bug.

	* tests/get/defsid.sh: Wrote tests for the default-SID flag.

	* tests/admin/flags.sh:
	Since we now emit a couple of error messages relating to the "-b"
	flag, we need to IGNORE some of the stderr output in the tests,
	otherwise we procude unwarranted test failures.

	* tests/sccsdiff/rap.sh:
	We can't count on the precise form of the output, but we can count on
	the exit status of the command.   Tests amended for compatibility with
	SCCS.  SCCS now passes :-)

	* tests/get/branch.sh:
	Since we now emit a couple of error messages relating to the "-b"
	flag, we need to IGNORE some of the stderr output in the tests,
	otherwise we procude unwarranted test failures.

	* sccsdiff.sh.in:
	SCCS compatibility fix -- When "get" fails, exit with value 1, not 2.

	* get.cc: Added warnings for when -b flag is ignored because the b
	(branch-enable) flag is not set, and for when -b is udes without -e
	(which does not make sense and is otherwise ignored).

	* _chmod.cc:
	Removed double leading underscore for #define used to prevent multiple
	inclusion.

	* sf-get2.cc:
	Fixed assertion failure for "get -e -r1.1.1 s.foo.c" when there is a
	revision 1.1.1.1.   Probably needs tidying (or at least
	re-generalising).

	* sf-chkid.cc:
	Export the function is_keyword_letter() so that our later support for
	binary as well as text files can be simplified.

	* sccsfile.h, sccsfile.cc: Added sccs_file::branches_allowed().

1998-01-20  James Youngman  <jay@gnu.org>

	* docs/cssc.texi:
	Added documentation on when and how branches are made.

1998-01-19  James Youngman  <jay@gnu.org>

	* tests/get/branch.sh:
	Added tests for the correct handling of the "-b" flag.

1998-01-18  James Youngman  <jay@gnu.org>

	* encoding.cc:
	First show at the uuencode/uudecode methods for the support of binary files.

1998-01-17  James Youngman  <jay@gnu.org>

	* unget.cc, what.cc, rmdel.cc, prs.cc, get.cc, my-getopt.cc,
	delta.cc, ChangeLog, admin.cc: Removed all colons from getopt()
	option descriptors.  Instead we replace them with "!", which tells
	our custom version of getopt() to parse the options in the SCCS
	style (arguments must follow keyletters and may not be in the next
	argv[] element).

	* cssc.h: Only include <config.h> if HAVE_CONFIG_H is defined.

	* configure.in: Updated the version number.

	* testutils/user.c:
	Added this file (which is broadly the equivalent of the standard Unix
	command "id").

	* NEWS: Changes for version 0.05 (changes in Dec 19997 and Jan 1998).

	* ChangeLog:
	Updated for version 0.05 (changes in Dec 19997 and Jan 1998).

	* docs/CREDITS:
	Added paragraph for Richard Polton, and de-emphasised the role of
	MySC.

	* docs/FIXED:
	Moved a bug report (99999 cap on nu,bers of lines in SCCS files) from
	BUGS to FIXED after fixing it.

	* docs/BUGS: Moved a bug report to the FIXED file after fixing it.

	* docs/missing.txt:
	Indicate that sccs-val and sccs-comb have not been implemented.

	* docs/TODO: *** empty log message ***

	* docs/TESTING:
	Indicated that Richard Polton wrote the first contributed test suite.

	* docs/Platforms:
	Added indication that CSSC has been tested under Red Hat version 5.0.

1998-01-16  James Youngman  <jay@gnu.org>

	* docs/get-spec.txt:
	Updated to reflect the fact that the makefile no longer has a "make
	gtest" target.

1998-01-15  James Youngman  <jay@gnu.org>

	* docs/cssc.texi: Documented sact, cdc, rmdel, prt.

	* tests/Makefile.am: Added the test-cdc target.

	* tests/common/test-common:
	The expected stdout/stderr arguments are quoted when they are output
	to temporary files, to prevent any wildcard characters iin them being
	expanded!

	* mystring.h: typo in comment

	* fileiter.h:
	Provide using_stdin(), which indicates if stdin is already in use for
	reading a list of files to operate on.

	* prompt.cc:
	The prompt should not be issued if stdin is not a terminal.

	* sf-cdc.cc, cdc.cc: Using the new test cases, fixed many bugs!

	* tests/cdc/4order.sh, tests/cdc/2comment.sh, tests/cdc/3MRs.sh,
	tests/cdc/1general.sh: Wrote a fairly comlete set of test cases
	for 'cdc'.

1998-01-10  James Youngman  <jay@gnu.org>

	* tests/Makefile.am: Added tests for "sccsdiff".

	* tests/sccsdiff/rap.sh:
	Export $get so that "sccsdiff" can call the correct "get" program.

	* Makefile.am: Renamed list.h to mylist.h.

	* sccsfile.h, sid_list.cc, run.cc, run.h, pipe.cc, rel_list.h,
	l-split.cc, pfile.h, fileiter.h, mylist.h, list.h: Renamed
	"list.h" to "mylist.h".
2019-05-06  James Youngman  <jay@gnu.org>

	Fix more compiler warnings.
	* src/what.cc: Forward-declare usage().
	* src/sccsfile.h: Declare print_flag2() functions.
	* src/get.cc (main): Format the (unsigned in) line count with %u
	instead of %d.
	* src/environment.cc (max_sfile_line_len): Simplify a complex
	boolean expression to silence a compiler warning suggesting
	parentheses.
	* src/writesubst.cc (write_subst): Print the output line number
	with %u since it is an unsigned int.
	* src/sf-write.cc (write_delta): Remove unsed variables "len" and
	"i".
	(write): Likewise, also "s".

	Fix some compiler warnings. Also turn off warning options which
	themselves just generate warnings.
	* src/run.cc (run): Avoid mixing signed/unsigned quantities.
	* src/sf-get2.cc (get): Avoid variable 'd' shadowing a variable of
	the same name in an outer scope.
	* src/sccsfile.h: Declare print_flag().
	* src/cap.cc (cap_min): Simplify this function; we only use it for
	trivially copyable types anyway.
	* configure.ac: Disable some warnings known to the manywarnings
	module (thus enabled with --enable-warnings) but which aren't
	suitable for C++ compilation.  We disable them so that we don't
	get a warning message from GCC about the inappropriate warning
	option.

	Use block I/O for encoded streams.
	* src/encoding.cc (encode_line): return the number of bytes
	output.
	(encode_stream): Use the count returned by encode_line to perform
	block I/O (with fwrite) instead of string I/O (with fprintf).

	Move the implementation details of uuencoding/decoding into a
	separate namespace.
	* src/encoding.cc (encode): Put into an encoding_impl namespace to
	emphasize that it is not intended as a public API for the rest of
	the program to use.  It's not in an unnamed namespace since the
	unit test still needs to use it.
	* src/bodyio.h (encoding_impl): Put declarations of encode and
	decode into this namespace.
	* unit-tests/test_encoding.cc: Use the namespace-qualified names
	for encode and decode.

	Delete mylist.h.
	* src/mylist.h: Delete mylist.h
	* src/Makefile.am (noinst_HEADERS): Delete mylist.h
	* src/sccsfile.cc: Don't include mylist.h.
	* src/l-split.cc: Don't include mylist.h.
	(split_comments): use std::vector<T> instead of mylist<T>.
	* unit-tests/test_bigfile.cc: use std::vector<T> instead of
	mylist<T>. Don't include mylist.h.
	* unit-tests/test_delta.cc: Likewise.
	* unit-tests/test_mylist.cc: Delete.
	* unit-tests/Makefile.am (unit_tests): Remove test_mylist.

	Switch class sccs_file from mylist<T> to vector<T>.
	* src/sccsfile.h: use std::vector<T> instead of mylist<T>.
	* src/sf-val.cc: Likewise.
	* src/cdc.cc (main): Likewise.
	* src/sf-prt.cc: Likewise.
	* src/admin.cc (main): Likewise.
	* src/sf-cdc.cc: Likewise.
	* src/sf-admin.cc: Likewise.
	* src/sf-write.cc: Likewise.
	* src/get.cc (print_id_list): Likewise.
	* src/sf-get.cc (prepare_seqstate_1): Likewise.
	* src/sf-prs.cc (print_seq_list): Likewise.
	* src/sf-rmdel.cc (is_seqlist_member): Likewise.

	Switch test_delta-table.cc from mylist to vector.
	* unit-tests/test_delta-table.cc: Switch data structures from
	mylist<T> to std:vector<T> (for which mylist is an alias anyway).

2019-05-05  James Youngman  <jay@gnu.org>

	Switch class release_list from using mylist<T> to vector<T>.
	* src/rel_list.h: Switch data structures from mylist<T> to
	std:vector<T> (for which mylist is an alias anyway).
	* src/rl-merge.cc (remove): Likewise.

	Switch class sccs_file_iterator from using mylist<T> to
	vector<T>.
	* src/fileiter.h: Switch data structures from mylist<T> to
	std:vector<T> (for which mylist is an alias anyway).

	Switch class delta from using mylist<T> to vector<T>.
	* src/delta.h: Switch data structures from mylist<T> to
	std:vector<T> (for which mylist is an alias anyway).
	* src/delta.cc (delta_main): Likewise.
	* src/sf-delta.cc (add_delta): Likewise.

2019-05-05  Martin Wilck  <mwilck@suse.com>  (tiny change)

	sccs: comply with POSIX POS36-C rule.
	POS36-C compliance requires that setgid() is called before
	setuid(), and both called after relinquishing extra groups with
	setgroups(). See
	https://wiki.sei.cmu.edu/confluence/display/c/POS36-C.+Observe+correct+revocation+order+while+relinquishing+privileges
	* configure.ac: check for setgroups()
	* src/sccs.c (drop_privs): correct call order: setgroups, setgid,
	setuid.

2019-05-05  James Youngman  <jay@gnu.org>

	Suggest setting CSSC_DISABLE_VALGRIND=1 if system binaries cause
	tests to fail.
	* README (--disable-valgrind): point out that occasionally, a
	system binary will cause Valgrind checking to make tests
	fail. Explain how to work around this problem.

	Include config.h before other files.
	* build-aux/find-out-of-order-includes.sh: Script for identifying
	source files which include other headers before "config.h", which
	gnulib doesn't like.
	* src/version.cc: Include "config.h" before <stdio.h> to avoid
	complaints from gnulib.

2016-03-01  James Youngman  <jay@gnu.org>

	Don't distrubite unit-tests/googletest/Makefile.in.
	* unit-tests/Makefile.am (EXTRA_DIST): Don't include
	googletest/Makefile.in, since we don't create that file, as
	googletest is not in SUBDIRS.

2016-02-28  James Youngman  <jay@gnu.org>

	Add tests covering p-file validity checks in sact.
	* src/pfile.cc (sccs_pfile): Validate the delta SID (instead of
	only the gotten SID).  When rejecting an invalid date, say
	"date/time", since it may in fact be the time field which is
	incorrect.
	* tests/common/test-common: New options to docommand,
	--stderr_regex and stdout_regex, allowing regex (egrep) matching
	of tool output.  Each has a --no* counterpart which turns the
	option off again (this is useful for deteating the defaults
	provided by functions which wrap docommand).
	* tests/sact/pfile_corruption.sh: New test, covering the p-file
	validity checks in sact.

2016-02-24  James Youngman  <jay@gnu.org>

	Don't use unique_ptr on the result of strdup, and other cleanup.
	* src/sccsdate.cc (y2k_window): move all year windowing
	calculations into this new function.
	(is_leapyear): fix typo in comment.
	(get_two_digits): Add specialization which takes a constr
	string&.
	(sccs_date::sccs_date): Use y2k_window.  Also, instead of using
	unique_ptr on a pointer returned by strdup, just use a std::string
	instance.
	* src/sccsdate.h (class sccs_date): Remove the daysecond field.

	Fix a number of problems identified by "make syntax-check".
	* src/get.cc: Remove trailing blanks.
	* src/Makefile.am: Likewise.
	* src/l-split.cc: Likewise.
	* src/get.cc: Likewise.
	* src/prs.cc: Likewise.
	* src/run.cc: Likewise.
	* src/sccsfile.cc: Likewise.
	* src/sccsfile.h: Likewise.
	* Makefile.am (distcheck-hook): Remove trailing blank.
	* src/sccs.c (gstrncat): Avoid spurious warning about reference to
	strncpy() in a comment.
	* tests/val/historical.sh: Remove empty lines at EOF.
	* unit-tests/test_linebuf.cc: Likewise.
	* build-aux/check-googletest-files.sh: Remove empty lines at EOF.
	(deleteprefix): Remove trailing blanks.
	* NEWS: Change "the the" to "the" in item for CSSC-1.3.2.  Remove
	trailing blanks.
	* src/sccsdate.cc (sccs_date::sccs_date): Avoid the use of strncpy.
	* docs/cssc.texi (Admin Options): Don't say "see also @xref".
	(Executable File Support): Remove trailing blanks.
	* src/sf-prs.cc (prs): Don't use the space-tab combination.
	* src/file.cc (get_mode_bits): Remove trailing blanks.
	(is_writable): Likewise.

	Make mylist a simple synonym for std::vector.
	* src/mylist.h: Make mylist a simple synonym for std::vector.

	Don't require mylist<T>::operator[] to assert on index errors.
	* unit-tests/test_mylist.cc: Remove tests which verify that
	mylist<T>::operator[] assert-fails when an index is out of range
	(since std::vector does not do this).

	Stop depending on mylist not actually being a synonym for std::vector.
	* src/sf-prs.cc (print_string_list): Remove the two versions of
	this function for std::vector<string> and mylist<string>.
	Instead, implement a single template function which takes a range
	of iterators.  This allows us not to care wither mylist is simply
	compatible with std::vector, or actually is std::vector.
	(print_delta): Update callers of print_string_list.

	Include <algorithm> where it is needed, and not where it is not.
	* src/sf-rmdel.cc: include the <algorithm> header since we use
	std::find.
	* src/mylist.h: Don't include <algorithm>, the transitive
	inclusion of which sf-rmsel.cc was previously takign advantage
	of.

	Replace constructor from const set& with a range of iterators.
	* src/mylist.h (mylist::mylist): Add constructor from a range of
	input iterators, allowing initialization from any container.
	Remove the special-purpose constructor from const set&.  This
	change provides closer compatibility with std::vector<T>,
	* src/delta.h (delta::delat): Initialize included_ and excluded
	using the iterator range instead of plain const set&.

2016-02-23  James Youngman  <jay@gnu.org>

	Remove mylist<T>::operator+=(), implementing insert() instead.
	* src/mylist.h (mylist::insert): add insert() method, forwarding
	to std::vector<T>::insert(), as a replacement for
	mylist::operator+=() (and that method is removed).
	(mylist::cbegin): add, forwarding to items_.cbegin().
	(mylist::cend): add, forwarding to items_.cend().
	* src/delta.h (delta::prepend_comments): Implement.
	* src/sf-cdc.cc (sccs_file::cdc): Call mylist::insert() instead of
	the removed mylist<T>::operator+=().  Also use
	delta::prepend_comments() to prepend comments instead of copying
	the old comments, modifying the list and callign set_comments().
	* unit-tests/test_mylist.cc (MylistTest::Catenate::TestBody): use
	the new insert method to perform the concatenation, instead of the
	removed method operator+=.

2016-02-21  James Youngman  <jay@gnu.org>

	Avoid unnecessary for loop in mylist::operator+=(const mylist&).
	* src/mylist.h (mylist): Implement operator+= with a range insert
	on the underlying vector.

	Remove mylist<T>::operator-=(const mylist<T>&).

	mylist<T>&).

	* unit-tests/test_mylist.cc: Remove tests of
	mylist<T>::operator-=(const mylist<T>&).
	* src/sccsfile.h (sccs_file::admin): change the type of
	erase_users from mylist<string> to
	std::unordered_set<std::string>.  This allows the implementation
	to be more efficient without affecting the ordering of the
	resulting user list.
	* src/admin.cc (main): Update the type of erase_users
	accordingly.
	* src/sf-admin.cc (admin): take advantage of the efficiency of
	std::unordered_set<T>::find() when computing the updated
	authorized user list.  Hence we no longer need to call
	mylist<T>::operator-=(const mylist<T>&).

	Delete mylist<T>::add(), preferring push_back() instead.
	* src/mylist.h (mylist): Delete mylist<T>::add() since we prefer
	push_back().

	* unit-tests/test_mylist.cc: remove tests for mylist<T>::select().

	Remove mylist<T>::operator=(void*).

	effect of this method was to clear the list, so add a clear()
	method instead, for closer matching to std::vector.n
	* unit-tests/test_mylist.cc: remove tests for
	mylist<T>::operator=(void*).

	* src/sf-admin.cc (sccs_file::admin): use clear() to clear an
	instance of mylist<T>, not assignment to NULL.

	Remove mylist<T>::length().
	* src/mylist.h (mylist::length): delete this method (size() should
	be used instead).

	result of length() against 0.
	* src/fileiter.cc (next): Prefer mylist::size() to
	mylist::length().
	* src/sf-admin.cc (sccs_file): Likewise.
	* src/sf-val.cc (validate_seq_lists): Likewise, factoring repeated
	code out into a new function, validate_seq_numbers.
	* src/sf-rmdel.cc (is_seqlist_member): use std::find instead of
	iterating over list members ourselves.
	* src/sf-prt.cc (print_seq_list): use a range-based for loop
	rather than iterating over the indexes in a mylist<seq_no>.
	(sccs_file): Instead of checking mylist<T>::length() against 0,
	use the empty() method.

2016-02-20  James Youngman  <jay@gnu.org>

	Prefer mylist::size() to mylist::length().
	* unit-tests/test_delta.cc: Don't use mylist::length().
	* unit-tests/test_bigfile.cc (emit_comments_or_mrs): Don't use
	mylist::length().

	Prefer mylist::size() to mylist::length().

	length() method, for better compatibility with (and so simpler
	transition to) std::vector.

	Avoid bash-specific [[...]].
	* build-aux/check-googletest-files.sh (findproblems): Avoid
	[[...]] since that is a Bash feature, and this is a /bin/sh
	script.

	Add a menu for "admin", correcting a Texinfo build failure.
	* docs/cssc.texi: Updated copyright years.
	(admin): Added a menu for the sections relating to "admin".

	member variable).
	(gfile_should_be_executable): Implement (when this method returns
	true, the gotten file should be executable).
	(sfile_should_be_executable): Implement (when this method returns

	(sccs_file): If the history file is executable, remember this so
	that the gotten file is created with the relevant execute bits
	set.
	* src/get.cc (main): The gotten file should be executable if

	* tests/admin/executable.sh: New test file; verifies that the

	history file.  Verify that setting the 'x' flag cuases the g-file
	to be created executable, and that not setting it does not (when
	the history file is not executable).  Verify that the history file
	can still be set as executable when the initial body is presented
	on stdin.

	* tests/common/test-common (docommand): Show the label for the
	current command in command.log.

2014-07-11  James Youngman  <jay@gnu.org>

	Release CSSC-1.4.0.
	* configure.ac (AC_INIT): Update the version number.
	* NEWS: Describe the new release.

2014-06-30  James Youngman  <jay@gnu.org>

	Release CSSC-1.3.2.
	* configure.ac: Change version number to 1.3.2.
	* NEWS: Update the version number of the first section.

	Update googletest unit test framework from r424 to r690.
	* gl/lib/.gitignore: Add the files generated by the pthread module
	(since we now depend on that).
	* bootstrap.conf (bootstrap_epilogue): Upgrade from r424 to r690
	of the googletest test framework.
	(buildreq): Update tool versions to the ones I'm actually using
	now, since these are really the only tools I test with routinely.
	(gnulib_modules): Depend on the pthread module.  Download
	googletest before we run gnulib-tool (instead of in the epilogue),
	so that the googletest/m4 directory is available to autoconf.
	* configure.ac: Include the googletest m4 library,
	unit-tests/googletest/m4.  Turn on the Automake option 'tar-ustar'
	which switches the dist file format from v7 Unix to the selects
	the ustar format defined by POSIX 1003.1-1988.  We need to do this
	since the distribution now contains path names longer than 99
	characters and the v7 format (or its consumers) cannot reliably
	deal with this.  Also make explicit some of the options which in
	any case are implied by the "gnits" option, since we would want to
	keep them even if turning off gnits.  Add configure tests required
	by the googletest framework.

	* NEWS: Point out the change of tar file format used for the
	distribution file.  Also mention the recent updates to googletest
	and gnulib.
	* unit-tests/Makefile.am: Update the build rules used to build the
	googletest unit test framework.  Don't build the samples.  Build
	libgtest by compiling individual source files, instead of only
	libgtest-all.cc (this fixes a problem in which "make distcheck"
	would otherwise fail due to dependency rule files being left
	around.  Also, don't compile the sample programs.  Remove the
	rules for fusing the sources.  We don't use them, and the rules
	themselves are still available in googletest/Makefile.am.
	* Makefile.am (ACLOCAL_AMFLAGS): Include the googletest m4
	library.
	(distcheck-hook): Call build-aux/check-googletest-files.sh
	(this is described below).
	* build-aux/check-googletest-files.sh: New script; verifies that
	all the files for the "googletest" C++ Unit test framework are
	included in the distribution.  This script is called from
	distcheck-hook.
	* .gitignore: Don't ignore build-aux.

	Update gnulib.
	* bootstrap: Update from current gnulib.
	* bootstrap.conf: Remove second (and wrong) --tests-base
	argument.  Don't munge include paths in gl/tests/Makefile.am
	(since now, doing that breaks the build and whatever made it
	necessary before no longer does).
	* src/canonify.cc: Include <config.h> before (gnulib's replacement
	of) <unistd.h>.

	* src/file.h: Include <sys/types.h> for gid_t.

2013-04-20  James Youngman  <jay@gnu.org>

	Typo fix.
	* COPYING.bsd: Fix typo 'modifiactions'.

2011-11-19  James Youngman  <jay@gnu.org>

	Fix Savannah bug #33633 (coredump in prs -d:GB:)
	* src/sf-prs.cc (sccs_file::get): pass in the correct delta
	information for keyword expansion instead of a blank (that is,
	invalid) delta.  This fixes Savannah bug #33633.
	* tests/prs/sv33633.sh: New file, test for this bug.
	* tests/prs/s.sv33633.txt: Test input for the new test.
	* NEWS: Mention this bug fix.

2011-05-22  James Youngman  <jay@gnu.org>

	Add unit test for cssc_linebuf.
	* unit-tests/Makefile.am (unit_tests): Add test_linebuf.
	(test_linebuf_SOURCES): Build test_linebuf.
	* unit-tests/test_linebuf.cc: New unit test file.

2011-05-21  James Youngman  <jay@gnu.org>

	Print clearer test labels.
	* tests/common/test-common (docommand): Print the test directory
	and the test script as part of the label of each test, for
	additional clarity and because many of them are actually not
	unique.
	* tests/get/sf111140.sh (label_prefix): Print qualified labels (as
	for docommand).

	Source the command-names script only once per test script.
	* tests/common/real-thing: Instead of sourcing the command-names
	script unconditionally, just complain if it was not already
	sourced.
	* tests/common/command-names: Error out if the command-names
	script is sourced twice.
	* tests/common/config-data: Don't source the command-names script
	more than once.
	* tests/common/need-prt: Likewise.

	* tests/Makefile.am (test-*): Indicate the full path of each test
	script.

	Set TZ=GMT in the y2k tests.
	* tests/year-2000/ext.sh: Set $TZ to GMT in order to make it
	possible for implementations which convert SCCS file dates to
	time_t values (but which otherwise have no bugs) to pass the
	tests.
	* tests/year-2000/prs-y2k.sh: Likewise.

	Remove spurious space in definition of admin.
	* tests/common/command-names (admin): remove spurious space.

	Move on from release 1.3.1.
	* configure.ac: Update version number to 1.3.2-git, to indicate
	that compiled versions of this code are no longer identical to the
	1.3.1 release.
	* NEWS: Likewise.

2011-05-10  James Youngman  <jay@gnu.org>

	Release version 1.3.1.
	* NEWS: Update version number to 1.3.1.
	* configure.ac: Likewise.

	Check we distributed all the tests.  Remove redundant Makefile.am files.
	* auxfiles/check-testfiles.sh: New script (copied from GNU
	findutils e66802375963941b3b54a0e038d18eccde449e14 with some
	adaptations for CSSC) for checking that we installed all the test
	scripts in "make dist".
	* tests/Makefile.am (dist-hook): Invoke the
	auxfiles/check-testfiles.sh script.
	* tests/common/Makefile.am: remove unreferenced file;
	tests/Makefile.am does not recurse.
	* tests/delta/Makefile.am, tests/prs/Makefile.am: Likewise.
	* tests/prt/Makefile.am, tests/sact/Makefile.am: Likewise.
	* tests/admin/Makefile.am, tests/unget/Makefile.am: Likewise.
	* tests/val/Makefile.am, tests/what/Makefile.am: Likewise.

2011-05-03  James Youngman  <jay@gnu.org>

	Modify "prs -d :DI:" to print ignored deltas.
	* tests/prs/delta_ixg.sh: New test script for "prs -d :DI:".
	* tests/prs/s.delta_ixg: New test input file for delta_ixg.sh.
	* src/sf-prs.cc (print_delta): For :DI:, also print ignored
	deltas.  Follow the conventions of OpenSolaris 2009.06 on the
	question of how many slashes to produce.
	* docs/cssc.texi (Data Keywords): Describe in more detail just how
	the keyword :DI: is expanded.
	(SCCS Version Differences): Explain how the expansion of :DI:
	varies across implementations.
	* NEWS: Mention this change.

2011-04-30  James Youngman  <jay@gnu.org>

	Accept entirely empty comment lines (lacking the initial space).
	* src/sccsfile.cc (read_delta): Accept comment lines containing
	nothing at all (not even a space after the 'c').  Some historis
	versions of SCCS seem to have produced these, and later versions
	tolerate it.

	Fix Savannah bug bug #33153: "prs" includes "AUTO NULL DELTA"s.
	* src/prs.cc (main): Change type of all_deltas from int to bool.
	(main): Move detection of errors writing to stdout to here,
	instead of sccs_file::prs().  Likewise diagnosis of the fact that
	no deltas were matched.
	* src/sf-prs.cc (prs): Add an output parameter, "matched", which
	is set if any delta was matched (and printed).
	(prs): Rewrite this method to evaluate the earlier/later cutoff in
	terms of SIDs where this is necessary.  That is, avoid the
	assumption that different SIDs have different timestamps.
	* src/sccsfile.h (sccs_file::prs): Modify the declaration
	of sccs_file::prs() to add the output parameter, "matched".
	* tests/prs/sv33153.sh: New test.
	* tests/prs/s.sv33153: New test input file.
	* NEWS: Mention this bugfix.

2011-04-29  James Youngman  <jay@gnu.org>

	* testutils/mogrify.awk: Preserve comment lines which have no
	space (that is, \001Ac\n).

2011-04-26  James Youngman  <jay@gnu.org>

	Fix some minor issues identified by 'make syntax-check'.
	* testutils/uu_decode.c: avoid including unnecessary header
	<stddef.h>.
	* src/sf-delta.cc (add_delta): Remove doubled word in a comment.
	* docs/cssc.texi (Other Variables): Remove doubled word.
	(Year 2000 Summary): Likewise.
	* cfg.mk: Modify spelling of a comment in order not to have a
	false positive from the sc_makefile_at_at_check syntax check.
	* tests/year-2000/ext.sh: Remove blank line at the end of the
	file.
	* tests/year-2000/prs-y2k.sh: Likewise.
	* .x-sc_unmarked_diagnostics: Likewise.
	* unit-tests/testwrapper.sh.in: Add final newline.
	* README-hacking: Remove space-tab combinations.

	Update hacking instructions to explain the git submodule.
	* README-hacking: Update instructions detailing how to collect
	gnulib (since we now use it as a submodule).

	Update gnulib.
	* gnulib: update to current HEAD.

	Various minor fixes suggested by 'make syntax-check'.
	* docs/.ispell_english: Remove blank line from end of document.
	* src/Makefile.am: Remove blank space from end of line.
	* src/file.cc (atomic_nfs_create): Likewise.
	* src/sf-prs.cc (prs): Likewise.
	* testutils/lndir.c: Likewise.

	Change output order in "sccs unedit" to match OpenSolaris.
	* tests/bsd-sccs/driver-basic.sh (h1): Modify the ordering of the
	expected ouput to match OpenSolaris 2009.06.
	* src/sccs.c (command): For the UNEDIT case, flush stdout before
	invoking 'get' in order to pass the changed test.
	* NEWS: Mention this change.

2011-04-25  James Youngman  <jay@gnu.org>

	Allow non-CSSC implementations to XFAIL for tricky dates.
	* tests/year-2000/prs-y2k.sh: Divide tests into "easy" (which any
	y2k-compliant version of SCCS must pass) and "harder" (which
	require correct implementation of the windowing scheme and correct
	conversion of dates at the limits of a 32-bit time_t).  Require
	CSSC to pass all tests, but allow other implementations to XFAIL
	on the hader tests.
	* tests/year-2000/ext.sh: Correct the mechanism by which we figure
	out if we are testing CSSC itself.
	* tests/common/test-common (fail): return false on XFAIL.

	Move source and documentation out of bsd/ into src/ and docs/.
	* COPYING.bsd: Move from bsd/COPYING.bsd.
	* bsd/sccs.1: move to docs/sccs.1
	* bsd/sccs.c: move to src/sccs.c
	* tests/common/command-names: Locate the sccs binary in its new
	location.
	* src/Makefile.am (generic_CPPFLAGS): Put preprocessor flags here
	so that AM_CPPFLAGS and AM_CFLAGS can both refer to it, now that
	we have both C and C++ sources in this directory.
	(LDADD): Link against gnulib.
	(AM_CFLAGS): #define PREFIX for the benefit of sccs.c.
	(AM_INSTALLCHECK_STD_OPTIONS_EXEMPT): Exempt the binaries from the
	gnits install check which requires them to support --version and
	--help.
	* AUTHORS: Mention the new location of the COPYING.bsd file.
	* THANKS: Point to COPYING.bsd in its new location.
	* docs/.ispell_english: Incorporate contents of bsd/.ispell_english.
	* docs/Makefile.am: Add sccs.1 and sccs.me.
	* bsd/.ispell_english, bad/Makefile.am, bsd/Makefile.bsd: Delete.
	* bsd/sccs.me: move to docs/sccs.me
	* configure.ac: refer to src/sccs.c instead of bsd/sccs.c
	* Makefile.am (SUBDIRS): Remove bsd from SUBDIRS.
	* README: sccs no longer lives in bsd/sccs.

	Allow an empty MR list to be passed to admin.
	* tests/admin/init-mr.sh: Don't expect "admin -m" to interpret
	a plain "-m" as meaning an empty MR list.  Distinguishing the
	absence of an argument to -m requires a traditional SCCS argument
	processor, and this behaviour is incompatible with modern
	implementations of SCCS (for example OpenSolaris).
	* tests/admin/flags.sh: Likewise.
	* src/admin.cc (main): Allow an empty list of MRs to be specified
	to admin, for example "admin -fv -m' '".  OpenSolaris allows
	this, and we can no longer use the previous method which was to
	omit the optional argument.  Elminiate doubled space in error
	message.
	* docs/cssc.texi (admin): document this clearly.
	* NEWS: mention this change.

	Fix delta summary; when it goes to stdout, send other to stderr.
	* tests/get/delta-summary.sh: OpenSolaris get emits the delta
	summary (produced by get -L) to stdout and the SID of the gotten
	delta and the number of body lines to stderr.  Expect this
	behaviour.
	* tests/get/delta-summary.sh (L2e): Check that the "new delta"
	message also goes to stderr when we are using "get -e -L" (since
	the delta summary goes to stdout).
	* src/get.cc (print_id_list): New parameter, fp: the file handle
	to print the IDs to.
	(main): rename use_stdout to send_body_to_stdout (being a more
	accurate description).
	(main): add variable commentary, the file descriptor on which we
	announce which delta we're getting and so forth.   This is usually
	stdout, but if stdout needs to be used for something else (for
	example the delta summary), commentary can be set to stderr.
	* src/sf-get2.cc (get): Correct the spacing before the items in
	the delta summary.  Add a trailing newline.
	* NEWS: Mention this change.

	Produce better test diagnostics when a command unexpectedly fails.
	* tests/common/test-common (docommand): when the return value is
	zero, print any error message that had been issued on stderr.

	Update sccsdiff to work like sccsdiff on OpenSolaris.
	* tests/sccsdiff/rap.sh: Update the tests to match the results we
	actually get from sccsdiff on OpenSolaris.
	* src/sccsdiff.sh.in: Update to pass the modified tests.
	Specifically, use a different header for the case where -p is
	specified and when it's not.
	* NEWS: Mention this change.

	Call ${admin} in test preparations, not "admin".
	* tests/admin/y-flag.sh: when trying to deduce the properties of
	the admin command we're testing, invoke ${admin} (i.e. the thing
	we are testing) as opposed to "admin" (i.e. the system's
	already-installed version).  Add extra checks to verify that the
	right thing happened.

	Avoid assuming Unix semantics for st_nlinks in lndir.
	* testutils/lndir.c (quit): Accept errno argument; include the
	error string in the error message if it is nonzero.  Call vmsg
	instead of calling vfprintf directly.
	(mperror): Accept the errno value as a function argument.
	(vmsg): make a static function.
	(dodir): Eliminate n_dirs subdirectory counter; this is unreliable
	on filesystems which don't have Unix-like semantics for the
	directory link count (for example, ISO9660 on Solaris, VirtualBox
	shared folders on Solaris).  Also word error messages more
	explicitly.

	Avoid retrying link(2) when errno is set to ENOSYS.
	* src/file.cc (atomic_nfs_create): If link(2) fails with ENOSYS,
	there is no point in retrying.

	Bugfix for lndir on OpenSolaris: ignore . and ..
	* testutils/lndir.c (dodir): Ignore . and .. (on systems where
	readdir returns them).

2011-04-24  James Youngman  <jay@gnu.org>
	Tell the user to run "bootstrap" instead of "autogen.sh".
	* README: "autogen.sh" has been replaced by "bootstrap".

	Adopt Automake's "gnits" rules.
	* configure.ac: Use the "gnits" rules.
	* docs/CREDITS: Rename to THANKS to comply with the gnits rules.
	* docs/CREDITS.short.txt: Add missing final newline.

	Modernise configure.ac initialisation.
	* configure.ac: Use the new-style Autoconf/Automake initialisation
	which passes the version number to AC_INIT rather than to
	AM_INIT_AUTOMAKE.

	Update the version number.
	* configure.ac: Update version number to make a distinction
	between the tar file which results form "make dist" and the
	released 1.3.0 tar file.
	* NEWS: Similarly update the version number.

	Fix SF bug #1300722 (prs succeeds even if the SID is not found).
	* tests/prs/wrongsid.sh: New file; tests for "prs -r" when the
	specified SID does not exist.
	* tests/prs/default.sh: New file; tests the default behaviour of
	prs, both with -d and with no options at all.
	* tests/prs/cutoff.sh: New file; tests for "prs -e" and "prs -l".
	* src/prs.cc (main): Add a comment pointing out that specifying -d
	changes the default behaviour around which deltas are selected.
	* src/sf-prs.cc (prs): return a failure status if a SID was
	specified but not matched.
	* NEWS: mention this bugfix.

2011-04-22  Yann Dirson  <dirson@debian.org>  (tiny change)

	Fix SourceForge bug #1317916.
	* bsd/sccs.1: Avoid a groff warning in sccs.1 by removing some
	unnecessary blank lines.

2010-11-07  James Youngman  <jay@gnu.org>

	Prepare to release 1.3.0.
	* configure.ac (AM_INIT_AUTOMAKE): Update the version number.
	This release is otherwise identical to 1.3.0rc1.
	* NEWS: Mention this.

2010-05-16  James Youngman  <jay@gnu.org>

	Prepare to release 1.3.0rc1.
	* NEWS: Update version to 1.3.0rc1
	* configure.ac: Update version to 1.3.0rc1
	* docs/cssc.texi: Update VERSION, EDITION and last-update time.

	Remove exceptions for now-deleted googletest/ files.
	* .x-sc_prohibit_empty_lines_at_EOF: Remove exceptions for
	nonexistent files.
	* .x-sc_prohibit_magic_number_exit: Likewise.
	* .x-sc_useless_cpp_parens: Likewise.
	* .x-sc_the_the: Likewise.
	* .x-sc_file_system: Likewise.
	* .x-sc_m4_quote_check: Delete this file, since the only entry in
	it has also been deleted.

	Remove some trailing blanks.
	* src/file.cc (create): Remove trailing blanks.

	Distribute ChangeLog.2.
	* Makefile.am (ACLOCAL_AMFLAGS): Set to -I m4 to avoid a warning.
	(EXTRA_DIST): Add ChangeLog.2, which previously wasn't
	distributed.

	Don't use #pragma interface/implementation, they're not useful
	with GCC 2.7.2+.
	* src/quit.h, src/sccsdate.h, src/sccsname.h, src/sid_list.h,
	src/filediff.h, src/fileiter.h, src/filelock.h: Don't use #pragma
	interface.
	* src/file.cc, src/fileiter.cc, src/linebuf.cc, src/my-getopt.cc,
	src/my-getopt.h, src/quit.cc, src/sccsdate.cc, src/sccsname.cc,
	src/sf-get.cc, src/sf-kw.cc: Don't use #pragma implementation.

	Remove support for CONFIG_MSDOS_FILES and lock methods other than
	CONFIG_PID_LOCKING.
	* src/fileiter.cc (sccs_file_iterator): Remove support for
	CONFIG_MSDOS_FILES.
	* src/sysdep.h: Remove support for CONFIG_MSDOS_FILES.
	* src/filelock.h (cleanup): Remove support for CONFIG_NO_LOCKING.
	* src/file.cc (create): Remove support for CONFIG_MSDOS_FILES.
	(create): Remove support for CONFIG_SHARE_LOCKING.
	(do_lock): Remove support for CONFIG_SHARE_LOCKING.
	* src/defaults.h: Remove support for types of locking other than
	CONFIG_PID_LOCKING.  Remove support for CONFIG_MSDOS_FILES.
	* src/file.h (enum create_mode): Likewise.

	Generate config.h.in by running bootstrap.
	* configure.ac: Call AC_CONFIG_HEADERS instead of the obsolete
	AM_CONFIG_HEADERS.  This causes bootstrap to call autoheader,
	which needs to happen for config.h.in to be generated.

	Eliminate stack.h and the stack<T> template, since it is not used.
	* unit-tests/Makefile.am (unit_tests): Remove test_stack.  Also
	eliminate test_stack_SOURCES.
	* src/seqstate.h: Don't include stack.h.
	* src/stack.h: Remove.
	* unit-tests/test_stack.cc: Remove.
	* src/Makefile.am (noinst_HEADERS): Remove stack.h.

2010-05-15  James Youngman  <jay@gnu.org>

	* .x-sc_trailing_blank: Remove trailing-blank exceptions for most
	files.

	syntax-check warnings.

2010-05-14  James Youngman  <jay@gnu.org>

	Don't configure in unit-tests/googletest, it's gone.
	* configure.ac: remove call to
	AC_CONFIG_SUBDIRS(unit-tests/googletest).

	Disable pthread support (since we don't use pthreads).
	* unit-tests/Makefile.am (AM_CPPFLAGS): Pass -DGTEST_HAS_PTHREAD=0.
	* configure.ac: Don't include
	unit-tests/googletest/m4/acx_pthread.m4. Remove --with-pthreads.
	* gl/lib/.gitignore: Remove gnulib.mk, dummy.c.

	Update Google C++ Test Framework version at bootstrap time.
	* bootstrap.conf (bootstrap_epilogue): call get-gtest.sh at
	bootstrap time.

	* unit-tests/get-gtest.sh: Use svn's --non-interactive option.

	Configure and build googletest in our own configure/Makefile.
	* unit-tests/Makefile.am: Build the Google C++ Testing Framework
	code in this Makefile rather than forcing it to have its own
	configure.
	(EXTRA_DIST): Distribute the googletest copyright notice
	etc. too.
	(gtest_headers): List all the header files.
	(libgtest_a_SOURCES): List the source files separately, and the
	header files.
	(libgtest_main_a_SOURCES): List the header files too.
	* bootstrap.conf (bootstrap_epilogue): googletest now has no
	separate configure step, so no need to bootstrap in that directory
	either.
	* unit-tests/get-gtest.sh: Script for checking out the google unit
	test code.

	Move googletest to unit-tests/googletest.
	* unit-tests/Makefile.am (SUBDIRS): Recurse into googletest.
	Update paths to liibgtest.la.
	* bootstrap.conf (bootstrap_epilogue): bootstrap in uni-tests/googletest.
	* configure.ac: Configure in unit-tests/googletest.
	* Makefile.am (SUBDIRS): Remove googletest (since we moved it).
	* googletest/*: move to unit-tests/googletest/.

	Remove some redundant scripts and .cvsignore files.

2010-05-02  James Youngman  <jay@gnu.org>

	Remove redundant inclusion guards for unistd.h and string.h.
	* configure.ac: When deciding whether or not _POSIX_SAVED_IDS is
	defined, include unistd.h unconditionally, since if the inclusion
	fails, the answer will still be no.
	* cssc.h: Don't use ifdef HAVE_UNISTD_H.  Since we're using
	gnulib's unistd.h module, we will be able to include <unistd.h>
	unconditionally.
	* rename.c: Likewise.
	* remove.c: Likewise.
	* strstr.c: Likewise for HAVE_STRING_H and <string.h>, since the
	latter is provided by gnulib's string module.

	Disable some spurious errors about failure to call set_program_name.
	* .x-sc_program_name: Don't require the test tools to call
	set_program_name, since they don't link with gnulib.

	Use the gnulib module progname.
	* bsd/sccs.c: Include progname.h.
	Remove unused variable MyName.
	(show_version): Use program_name not MyName.

	name (instead of lib.a).
	(gnulib_modules): Import the progname module.
	* gl/lib/.gitignore: Ignore files from the progname module.

	Use $(FOO) in Makefile.am rather than @FOO@.
	* tests/Makefile.am: Automake defines $(VALGRIND) from @VALGRIND@
	automatically anyway.
	* cfg.mk (_makefile_at_at_check_exceptions): Exempt a couple of
	usages by the Google C++ Testing Framework.
	* Makefile.am: Use $(LIBOBJS) instead of @LIBOBJS@.
	* unit-tests/Makefile.am (AM_LIBS): Likewise for $(PTHREAD_LIBS).
	(AM_CXXFLAGS): Likewise for  $(PTHREAD_CFLAGS).

	Silence an error about m4 quoting in the Google C++ Testing Framework.
	* .x-sc_m4_quote_check: Silence error message about insufficient
	quoting in googletest/m4/acx_pthread.m4.  We do this rather than
	fixing the quoting in order to avoid subsequent merge problems and
	spurious diffs.

	Silence a spurious error about changing old NEWS entries.	
	* cfg.mk (old_NEWS_hash): Set old_NEWS_hash to the md5sum of a
	zero-length input in order to silence a spurious error about
	changing old NEWS entries.

	Standardise on the use of "file system" rather than "filesystem".
	* docs/cssc.texi (Filenames): Spell "filesystem" as "file system",
	following the example of the POSIX standard.
	* docs/Platforms: Likewise.
	* file.cc (atomic_nfs_create): Likewise.
	* tests/admin/hardlinks.sh: Likewise.
	* tests/admin/.x-sc_file_system: Exempt the Google Unit Test code
	from this requirement, since that will make later updates hard to
	merge.
	Also exempt ChangeLog files.

	Ignore some maintainer-makefile lint complaints I don't plan to fix.
	* .x-sc_error_message_period: Avoid syntax-check errors for error
	messages ending in a full stop.  Some error messages contain more
	than one sentence.
	* .x-sc_error_message_uppercase: Avoid syntax-check errors for
	error messages starting with a capital letter.

	Fix a maintainer-makefile if-before-free lint issue.
	* bsd/sccs.c (set_prefix): Remove useless if-before-free.

	Adopt the use of the gnulib maintainer-makefile module.
	(gnulib_modules): Add maintainer-makefile.
	
	Update to GNU Free Documentation License, Version 1.3 (from 1.2).
	* docs/cssc.texi (@copying): Update from FDL 1.2 to FDL 1.3.
	* bootstrap.conf (gnulib_modules): Import module fdl.

	* docs/fdl.texi: Symlink to ../gl/doc/fdl.texi.
	* NEWS: Mention this change.

	Don't create a spurious directory.
	* bootstrap.conf (local_gl_dir): Don't create {m4_base}.  Create
	${m4_base} instead.

	Remove obsolete file gnulib-tests/.gitignore.
	* gnulib-tests/.gitignore: Remove.

	Clean up core files in the unit test directory.
	* unit-tests/Makefile.am (COREFILES): Clean up "vgcore.*" files
	for distclean.
	* unit-tests/testwrapper.sh.in: Clean up core files once the test
	is complete, unless the core file signals a valgrind failure.
	Also inhibit core file generation int he first place (though this
	probably won't work for valgrind).

2010-05-01  James Youngman  <jay@gnu.org>

	Put the gnulib code, etc. into ./gl
	* bootstrap.conf (doc_base): Override doc_base, m4_base,
	source_base, tests_base, local_gl_dir.
	(gnulib_mk): Use Makefile.am, not gnulib.mk.
	(gnulib_tool_option_extras): Tests are in gl/tests.
	(bootstrap_epilogue): Use gl/tests/Makefile.am, not gnulib-tests/gnulib.mk.

	* configure.ac (SUBDIRS): Rename the gnulib source directory from
	lib to gl/lib.
	(AC_CONFIG_FILES): generate gl/Makefile gl/lib/Makefile
	gl/doc/Makefile gl/tests/Makefile.
	* Makefile.am (AM_CPPFLAGS): Pass -I gl/lib.
	* bsd/Makefile.am (AM_CPPFLAGS): Pass -I ../gl/lib.

	Adopt the use of the first gnulib module: dirent.
	* gnulib-tests/.gitignore: Ignore gnulib test files (since they're
	imported rather than checked into git).
	* lib/.gitignore: Ignore gnulib source files (for the same reason).
	* configure.ac (AC_CONFIG_FILES): generate lib/Makefile.a
	* Makefile.am (SUBDIRS): Add "lib", which is where the gnulib code is.

	* bsd/sccs.c: Remove HAVE_XXX_H header guards.
	Include dirent-safer.h.  Remove the hand-hacked dirent portability
	macros (and remove NAMLEN as a side-effect).
	(do_clean): Don't assume the NAMLEN macro is defined.
	* file.cc: Include dirent-safer.h.  Remove the hand-hacked dirent
	portability macros (and remove NAMLEN as a side-effect).
	(is_directory): Move this function here from fileiter.cc.
	* fileiter.cc: Include dirent-safer.h.  Remove the hand-hacked
	dirent portability macros (and remove NAMLEN as a side-effect).

	Show the value of $(VALGRIND) at the start of regression testing.
	* tests/Makefile.am (test-initial): echo $(VALGRIND).
	
	Add unit test verifying that we don't read uninitialised data in encode.
	* unit-tests/test_encoding2.cc: New unit test file.  Verifies that
	we don't read uninitialised data when we reach the end of the
	encoding input.
	* unit-tests/Makefile.am (unit_tests): Add test_encoding2.

	Avoid reading uninitialised input.
	* encoding.cc (encode_line): Encode the tail of the input without
	running over the end of in[].

	Handling of directories in get is mandatory in POSIX, so remove CONFIG_NO_DIRECTORY.
	* fileiter.cc: don't define CONFIG_NO_DIRECTORY
	(sccs_file_iterator::sccs_file_iterator): don't check CONFIG_NO_DIRECTORY
	* fileiter.h (class sccs_file_iterator): Likewise.
	* file.cc: don't define CONFIG_NO_DIRECTORY

	Use STL to implement mylist<T>.
	* mylist.h (mylist): Implement mylist<T> as std::vector<T>.
	* delta-table.h (mylist<T>::select(i)): delegate to l[i].
	* unit-tests/test_mylist.cc: Drop the requirement that the
	mylist<T> implementation does not need there to be a T::T(const
	T&) copy constructor.
	* mylist.h (mylist): Implement mylist<T>::operator==(const
	mylist<T>&) const, which the unit tests need.

	Inline delta::removed(), for a small performance boost.
	* delta.h (class delta): Inline delta::removed().

	conversion itself.

	Generate a larger test file.
	* unit-tests/test_bigfile.cc (main): Increase the number of deltas
	in the produced file to about 30,000.

	Switch to using an STL data structure to represent the delta list.
	* delta-table.h (stl_delta_list): Reimplement delta_list using
	STL, reducing the time it takes to validate an SCCS file with
	30,000 deltas from 45s to 3s.   Separate the cssc_delta_table
	class from the data structure (a typedef delta_list) for looser
	coupling.  Retain the old data structure in the unused class
	mylist_delta_list.
	* delta-table.cc (delta_at_seq_exists): Delegate to the
	delta_list.
	(delta_at_seq): Likewise.
	(cssc_delta_table::~cssc_delta_table()): Since we no longer have a
	pointer member, the destructor no longer needs to do anything.
	(cssc_delta_table::build_seq_table): Push down into
	mylist_delta_list.
	(cssc_delta_table::add(const delta&)): Don't call update_highest
	since this work is done in delta_list::add(const delta&).
	(cssc_delta_table::update_highest): Remove obsolete function.
	* dtbl-prepend.cc (prepend): Don't call obsolete method
	update_highest, and use the correct (updated) type for the class
	member l (delta_list).

	Performance improvement for val.
	* sf-val.cc (check_loop_free): Use an O(N) method of
	consistency-checking the delta graph, rather than the old O(N^2)
	method.
	* delta.h (class delta): Make accessor functions id(), date(),
	user(), seq() and prev_seq() inline.

2010-04-27  James Youngman  <jay@gnu.org>

	Avoid touching missing sequence numbers in 'get'.
	* sf-get2.cc (get): Don't call delta_table->delta_at_seq() for
	sequence numbers for which delta_table->delta_at_seq_exists()
	returns false.

	When generating the test output file, set the checksum correctly.
	* unit-tests/test_bigfile.cc: Set the file's checksum correctly.

	* configure.ac: Make valgrind exit with status 10 when there is a

	* sf-delta.cc (add_delta): Removed obsolete "XXX" comments.
	* sf-prs.cc (get): Likewise.
	* cdc.cc (main): Avoid initialising a sid object by assignment

	code coverage.
	* mystring.cc: Removed TODO comments which actually don't need to
	be done.

	* sf-admin.cc (admin): If all releases are locked ("admin -fla")
	and the user tries to unlock just one release, issue an error
	message (instead of just ignoring the attempt).
	* docs/cssc.texi (admin): Explain the (already existing)
	restriction and how to get around it.

	Implement "get -l", "get -L" and "get -lp".

2007-12-19  James Youngman  <jay@gnu.org>

	* what.cc: String constants chould be const.

	* sf-val.cc (validate_substituted_flags_list): Added missing
	return statement.

	* sccsfile.cc (sccs_file): Specify the member initialisers in the
	order they will actually be executed.

	* linebuf.h (class cssc_linebuf): Make buflen size_t rather than

	Update license to GPL version 3.
	* NEWS: Mention this change.
	* docs/cssc.texi (Copying): Put the GPL in a separate, unnumbered,
	section. 

	* docs/cssc.texi: Change license to version 1.2 of the GNU Free
	Documentation License.
	* docs/Makefile.am (cssc_TEXINFOS): Depend on fdl.texi, so that it
	gets distributed. 
	* NEWS: Mention this change.

	* docs/Makefile.am (cssc_TEXINFOS): Don't depend on
	config-info.text, since we don't actually use it.  This prevents
	us trying to rebuild the info file during "make distcheck", when
	the source directory is read-only anyway.
	* doc/texinfo.tex: Update to the version of texinfo.tex used in
	automake-1.8.  Yo avoid future compatibility issues, it makes
	sense to remove this file from CVS in fact, but we won't do that
	just yet. 

	* tests/bsd-sccs/delsfile.sh (cleanup): Also clean up ./s.foo when
	we're finished.

	Fix build problems caused by the fact that generating
	testutils/Makefile in the top level directory produces
	a Makefile that expects to use config.h, while we actually 
	want to use DEFS in the testutils subdirectory.
	* configure.ac: Call AC_OUTPUT only once.  Do not emit
	testutils/Makefile. 
	* testutils/configure.ac: Fixed typo.


2007-06-21  James Youngman  <jay@gnu.org>

	* bsd/sccs.c: Updated the copyright text to be consistent with the
	COPYING.bsd file (by removing the advertising clause).

	* sccsfile.cc (print_subsituted_flags_list): Return true if
	nothing failed (as opposed to falling off the end of the
	function).   This prevents spurious x-file write errors if the y
	flag is unset.

	* cssc.h: Require exception support to compile.  This is not
	strictly necessary for successful operation, but without exception
	support "get s.foo s.bar" will not process s.bar if we failed on
	s.foo.  So exception support is required for full SCCS
	compatibility.

2007-06-20  James Youngman  <jay@gnu.org>

	* bsd/sccs.c (unedit): Fix "sccs unedit /tmp/SCCS/s.foo will
	cause ./s.foo to be unlinked" bug, by forming the g-file name
	from the p-file name, as opposed to the name of the file on the
	command line (because the file named on the command line gould be
	either the g-file or the s-file).
	* docs/BUGS: Mention the bugfix.
	* tests/bsd-sccs/delsfile.sh: New test, for this bug.

	* .gitignore: Ignore Emacs editor backups.

	* cap.cc, val.cc: Add explicit template instantiation directives to
	support compilation with GCC's -fno-implicit-templates option.
	* dtbl-prepend.cc, fileiter.cc, sccs-delta.cc: ditto
	* sccsfile.cc: Ditto.  Also include "mylist.h" to get the method
	definitions for the templates.

	* .gitignore, docs/.gitignore, testutils/.gitignore: New files.

	* tests/common/test-common: Work around an apparent bug in Bash
	3.1.17(1) in which "$@$ac_c" expands to DEL${ac_c} when $1 is "".
	That broke echo_nonl, causing some tests to fail.

	Fixed SourceForge bug 966010, sccs sccsdiff -r cannot have space
	before revision number.   We still will have similar problems
	elsewhere in the suite, I suspect.

	* sf-prs.cc, sf-delta.cc:
	Fixed SourceForge bug 1045768: CSSC does not compile with gcc 3.4
