PRCS NEWS -- history of user-visible changes. -*- Text -*-
$Date: Mon, 02 Nov 1998 23:28:03 -0800 $
$ReleaseVersion: 1.2.11 $
Please send bug reports to prcs-bugs@XCF.Berkeley.EDU. See the file
`README' for a description of how to report bugs.
Changes since version 1.2.10
* ALERT! The MD5 code was not setting it's UINT4 type properly on
64-bit systems, causing strange behavior. If you are using a 64-bit
OS, please upgrade.
* Trouble was corrected in the waitpid()/select() loop in
syscmd.cc, the code that organizes the multiple outstanding child
processes. There was a loop that was busy-waiting on a few certain
operating systems, starving the children and degrading performance.
* Fixes to configure.in for proper CFLAGS and CXXFLAGS variable
handling, thanks to Mark Jefferys.
* Several patches to prcs.el have been submitted for Xemacs and Emacs
20 incompatibilities, as well as multiple repository support. These
have not yet been integrated because I don't have time and Jesse
Glick has been busy.
** Changes since version 1.2.9
* See http://www.doitnow.com/~iliad/Tcl/PFE/ for a tool that displays
PRCS version trees in a friendly manner.
* Rename a #define that breaks PRCS in glibc 2.1-current so as to
avoid trouble when glibc 2.1 is released.
* Correct a bug in prcs admin pdelete (fs_nuke_file), thanks to Mark
Jefferys.
* Merge a set of patches Lars Duening so that PRCS works on
BeOS. (Neat!)
* Includes version 1.31 of prcs.el from Jesse Glick.
* Correct a permission problem in the repository causing multi-user
collaboration difficulties. As noted by Daniel Villeneuve, it is
still possible to get a repository into a situation where the owner
cannot revoke privileges due to subdirectories being created by
other users. The only solution is a recursive directory copy, which
for one reason or another, I do not feel compelled to implement.
For now, the only way to retract priviledges in this situation is to
package and unpackage. However, now subdirectories are created with
appropriate permissions, insuring that a repository with its
permissions set properly at initialization will remain correct.
* Correct the documented behaviour of --disable-environment, it was
backwards.
** Changes since version 1.2.8
* Update for C++ changes in egcs-1.1. Thanks to Andrew Stitcher.
* Update a greatly improved prcs.el from Jesse Glick. See the new
documentation at the top of prcs.el.
* Fixed a few documentation typos. Thanks to Franois Pinard and
Daniel Villeneuve.
* Change the output of the "Index: " line in diff output so that the
Index line matches the from name in the context diff header. This
seemed to cause problems for some versions of patch.
* prcs info -l now outputs Project-Keywords.
* The configure option --disable-environment allows you to build
a binary free of any default environment variable settings. This
is intended for package maintainers.
** Changes since version 1.2.7
* RCS was replacing keywords in the working copy of the project
file. Correct this.
* Bug fix in execute: file extensions were incorrect when the last
`.' occured in a directory prefix.
* More renaming in regex code to prevent errors on Digital UNIX--this
is lame. I can't build on the Digital UNIX box I have access to
because the gcc fix-included headers (sys/types.h) are broken. Come
to think of it, I have this problem (fix-includes breakage) on
certain versions of AIX and HP-UX too... YMMV.
* New option -P (--exclude-project-file) causes diff to not output
differences between project files and checkout to not create the
project project file.
* `prcs diff --' now unsets any diff options, including those set in
the environment.
* Fix bug in `prcs admin pdelete' causing it to fail on some projects.
Pdelete now issues a warning when a project does not exist.
* Document recursive keywords and -P.
** Changes since version 1.2.6
* Correct the ``valid username'' test to allow leading numerals.
* Improved error message for permission denied on certain repository
files.
* Hopefully solve IRIX 64-bit ino_t template problem.
* Obtain updates and fixes to prcs.el from Jesse Glick.
* Change names produced by prcs diff: instead of
some/path/to/file.orig
some/path/to/file
it produces:
oldversion/some/path/to/file
newversion/some/path/to/file
This is to agree with the naming convention suggested by patch
2.5.3.
* Keyword replacement is now recursive.
(TodaysDate "Today's date is: $\Date$")
produces: $TodaysDate: Today's date is: Mon, 02 Nov 1998 23:28:03 -0800 $
(ThisWontCrash "This is bad: $\ThisWontCrash$")
produces: $ThisWontCrash: This is bad: |ThisWontCrash| $, while a
format leaves the `$' characters:
$Format: " $ThisWontCrash$"$
This is bad: $ThisWontCrash$
It is neccesary to prevent `$' characters from being replaced in
a non-formatted keyword or else text ends up being inserted into
the document outside of the keyword (everything after the first
`$').
Replacment of a keywords takes place on a string which is either
quoted contents of a $Format$ keyword or the defined value of an
outer-most regular keyword. When this string contains an instance
of keyword which is not currently being replaced, it recursively
outputs the value of that keyword. Processed text is not
reexamined. When spurious `$' characters are found inside a
regular keyword (not $Format$), they are replaced with the `|'
character.
All of this suggests more and more general macro replacement
facilities, but I haven't come up with any real uses for them. I
did this because I wanted to be able to write:
(ReleaseVersion "$\ReleaseMajorVersion$.$\ReleaseMinorVersion$.$\ReleaseMicroVersion$"))
So, if people are using this and can think of improvements or
future direction in the keyword department, I think its very
cool stuff... send feedback.
** Changes since version 1.2.6-vforktest
* The merge query now treats `!' for each rule, so you may take the
default for some rules and not other.
* Populate-Ignore and Project-Keywords entries are now merged during
`prcs merge'. Procedure:
- After all files have been merged, populate ignore strings and
project keyword pairs are merged.
- Progress during these stages is not recorded, as it is for files.
This means that quitting in the middle of this stage will result
in starting the populate ignore and project keywords merge over
again. Since a merge not supporting 3-way reconciliation is
idempotent (mostly), this is not a big issue.
- The help strings will be a little confusing during these stages,
I may fix this.
** Changes since version 1.2.5
* Replace most fork calls with vfork calls in an attempt to port PRCS
to Amiga. Add configure tests for fork and vfork.
** Changes since version 1.2.4+egcs
* Remove __GNU_LIBRARY__ logic from getopt source files. PRCS uses
a modified getopt_long routine, so this code needs to be compiled
whether glibc is available or not.
* Rename functions in regex.{c,h} with a global replacement of "re_"
to "re2_". This is to prevent the following problem:
PRCS links with g++
g++ supplies -lg++ to the link line
libg++ contains static initializer code for regex code in libg++
The static initializers resolve to regex code in PRCS
Regex code in PRCS is different enough to cause bad things to happen
when these static initializers run, PRCS would core dump before
reaching main.
** Changes since version 1.2.4
* PRCS now compiles with egcs-1.0.2. I have only tested this release
on the following compiler/platform combinations, and would
appreciate hearing from users with other versions of g++:
Linux 2.0.33 gcc version egcs-2.90.27 980315 (egcs-1.0.2 release)
SunOS 5.5.1 gcc version 2.7.2.2
* Minor bug-fix to prcs.el.
** Changes since version 1.2.3
* Fix a bug in handling of irregular filenames (spaces, etc).
* Checkin now prompts 'abort' for checkin conflicts, while force
continues the checkin. This is the only prompt in PRCS where
the force behavior is different from the default behavior.
* Merge now prompts 'yes' for rename.
* Merge now creates subdirs before renaming a file into the subdir.
This was causing merge to abort.
* An environment variable set to empty is treated the same as an
unset variable, allowing users to unset a variable with compile-time
default.
* Fix a bug causing diff to fail on unset symlinks in the working version.
* Add the recently introduced prcs.el (including a PRCS major mode) to
the distribution.
* Automatically fills in the ChangeLog with the contents of i
New-Version-Log.
* Commands for checkin, diff.
* Incorporate Jesse Glick's modifications to prcs.el, prcs-ediff.el, and
prcs-ediff:
* add a new, simple parse function for parsing without position
information.
* cache project file parsing
* add a variable prcs::is-prcs-controlled to indicate that a file
is under prcs's control.

(push '("\\.prj\\'" . prcs-mode) auto-mode-alist)
* enhance the emerge interface, see the script scripts/prcs-ediff in
the distribution. you need perl 5 and gnudoit.
* display prcs modification status in the modeline.
** Changes since version 1.2.2
* Fix a bug causing a crash during merge of two symlinks.
* Fix a (supposed) bug causing a crash when password lookup
fails to return an entry.
* When subdirectory creation must create a directory by replacing
a non-directory, PRCS now asks the user whether to delete the
file. With --force, PRCS automatically removes the file.
* Fix a bug in execute --pipe on repository project versions,
it no longer reports an error for the project file.
* Populate now adds a bit more information to the comment it
inserts above it's modifications.
** Changes since version 1.2.1
* Fixed two bugs in merge, related to files with no-keywords set.
Caused no-keyworded files to be replaced by other files in the
project during merge.
* 'prcs execute --all' had an assertion failure when no files matched
the --match criteria.
** Changes since version 1.2.0
* Correct a problem with the code that finds the common version
between two project versions. This caused several problems
ranging from exponential time to compute the common version after
several merges, to checkin incorrectly reporting an ambiguous
common version.
* Correct a bug which caused PRCS to report a project unmodified
at checkin after certain merge operations.
* Correct a bug in the code that invokes the PRCS_CONFLICT_EDITOR
during merge.
* Correct a bug in merge causing merge of symbolic links to fail
during 'add'.
* Correct a bug causing file-list attributes such as
(Files :tag=something
(file1 (...))
(file2 (...))
)
to be written out as
(Files :tag=something
(file1 (...) :tag=something)
(file2 (...) :tag=something)
)
* Added new command 'prcs admin pinfo' for listing all projects in
the repository.
** Changes since version 1.2.0b8
* Documentation updated through version 1.2.0.
* Loosen test for correct versions of diff and rcs (so that it will
work with future versions).
* More corrections to the time-zone problem by Paul Eggert, and
upgrade time functions extracted from GNU patch 2.4 (maketime.c,
maketime.h, partime.c, partime.h).
* Correction to "make_obsolete" call pointed out by Ulrich Pfeifer
when using PRCS_MERGE_COMMAND.
* Comments are no longer retained inside file entries. Formerly,
comments such as
(foo ;; THIS
(...) ;; AND THIS
:symlink ;; AND THIS TOO
)
were retained. Now, they are removed and the entire entry will
be printed out as (foo (...) :symlink). Unfortunatly, this affects
past project files as well. All other comments (except those inside
Merge-Parents and New-Merge-Parents) are retained.
* Merging with different file types, symlinks, etc. works now, it
core dumped in 1.2.0b8.
* Fixes to execute pointed out by Jesse Glick.
** Changes since version 1.2.0b7
* New option --plain-format turns off any special formatting of
the output. Also affected by environment variable
PRCS_PLAIN_FORMAT.
* New option --sort=TYPE affects the order in which info outputs
version history. It currently accepts two arguments, "version"
and "date". Sorting by version is the old, default behaviour which
sorts versions by their version number, starting with the major
versions ordered by date. Sorting by date is a new behaviour, and
sorts all versions by date, regardless of their major version.
* Documentation updated for all the changes that have occured since
version 1.1.1 (Sort of. It's close, at least.).
* Apply TSUKADA Satoru's patch to hopefully fix the timezone problem
noted in the TODO file.
* The project file syntax is extended. You may now have more than
one (Files ...) statement, the result being as if you appended the
contents of each. The Files statement may now contain file
attributes that apply to all files in the list. These attributes
must precede all files in the list, for example:
(Files
:no-keywords
(filea ())
(fileb ())
(Files
:symlink
(linka ())
(linkb ())
)
Keywords except the ':tag=TAG' keyword may not be repeated.
* Merge code completely rewritten. It's more robust, handles
all file types, generalized for arbitrary default actions, and
delays checking out files until absolutely neccesary (so it's a lot
faster). Merge now logs all modifications to the file PROJECT.log.
With -l, merge logs all actions (including those which result in
"no prompt" or "nothing"). I'm not sure I like the new output
formatting, please complain if you don't.
* Merge now uses several file attributes to set various parameters.
Each rule may have a new action associated with it. Each attribute,
`:mergerule1', `:mergerule2', ... `:mergerule14', may have a default
action set to one of the five characters 'a', 'd', 'm', 'n', or 'r'.
These correspond to the five actions normally presented by merge.
Certain restrictions apply. You may only set the default to add for
rules with a missing working file and non-missing selected file. You
may only set the default to merge or replace for rules with at least
the working and selected files present. You may only set the default
to delete for rules with the working file absent. For information on
each rule and the numbers, see the documentation or the merge tutorial
at http://www.xcf.berkeley.edu/~jmacd/merge.html. When the 'm' action
is taken merge uses the `:mergetool' attribute, if set, to find a
command capable of merging the files. The value of this attribute is
interpreted the same as the PRCS_MERGE_COMMAND environment variable,
which is used as the value of `:mergetool' in the default group,
unless mergetool is already defined there. All attributes are taken
from the first file which is not absent among the working file, the
selected file, and the common file, in that order.
* Diff now uses the `:difftool' attribute, if present to determine a
diff tool to use. This defaults to the value of the environment
variable PRCS_DIFF_COMMAND. Diff uses the to file's attribute, if
present, then the from file's attribute. There are some problems
here to sort out, because the project file, for example, has no way
of setting it's difftool.
* Read operations on compressed repositories were leaving uncompressed
temporary files in TMPDIR for the duration of the command, now it
removes files when they are no longer needed.
* As a seperate part of merge, merge now detects renaming between the
common version and selected version and offers to let you rename the
file. The name of a file and the merging of it's contents are
completely seperate operations, one occuring before the other.
* The -F flag was removed. The new behaviour is to match files either
by file-family (as with the -F flag) or by name (as without) and
resolve ambiguity only when it arises by asking the user what to do.
With -f present, the match by file-family is chosen.
** Changes since version 1.2.0b6
* Compile-time defaults for the 8 documented environment variables
used by PRCS are taken and used as the default when a user runs
PRCS without the environment variable set. The autoconf stubs
for this are auto-generated as part of the build process. So,
PRCS checks first the users's environment, then the builder's
environment, and finally uses the documented default.
** Changes since version 1.2.0b5
* Remove bogus use of undefined MAX macro in vc.cc, fixing compilation
troubles on several systems.
* Slight changes to output of checkin -l. It no longer reports a file
has been modified or has a new mode after declaring that the file
was added.
* Elaborate on the "chmod failed at new repository entry creation"
error so as not to make users think an error occured in checkin.
* Apply Ulrich Pfeifer's (modified) patch to use an external merge
editor. See documentation for the PRCS_MERGE_COMMAND env var.
* The script 'prcs-emerge' is included in the distribution but not
installed. It is one possible external merge editor. It uses a
lisp function defined in prcs.el, which is now installed. Uses
gnudoit, so you need to have that working. Once you have gnudoit
working, run prcs merge with the PRCS_MERGE_COMMAND environment
variable set to 'prcs-emerge' and with 'prcs-emerge' in your path.
I wouldn't do this until you're comfortable with how emerge works.
* Fix infinite loop in merge code. Only present in version 1.2.0b5.
* Absolute path no longer requred for PRCS_CONFLICT_EDITOR, nor for
PRCS_MERGE_COMMAND.
** Changes since version 1.2.0b4
* 'prcs execute' now includes the project file in the list of files
with the special tag :project-file. Update your uses of this
command to use --not=:project-file if this will affect your usage.
Directories not explicitely named with :directory are now included
with :implicit-directory.
* Fix behaviour of symlink-following related code. It caused
checkout over a regular file by following symlinks to fail.
* Remove rx-1.5, replace with GNU regex package. It seems to be
64-bit clean, so the Alpha users can be happy. This makes populate
and execute once again capable of regular expression matching.
For those of you who think, "but my libc has POSIX regex stuff",
well, this one seems to be a challenging configure test so I'm
going to stick with it the way I have it now.
* Fix repository-lock permission problem, causing stale lock problems.
* Once again change the suffix used to name obsolete files during
merges. It was suggested that using the emacs suffix "~N~" was
a bad idea because people might tend to delete those files more
readily than they would their obsolete PRCS-controlled files. The
new suffix is ".vN". (And may I once again recommend checking in
before merging).
* Correct the -n switch for "prcs admin rebuild".
* Add to the mmap configure test a few suggestions made by Paul
Eggert. This turns off mmap for Solaris 5.4, HP-UX 9.x
and HP-UX 10.x. Users are free to set HAVE_MMAP if they disagree.
* File permissions on repository files were not being set correctly
at initial checkin. Fixed.
* General improvements to the repository permissions stuff, lock
permissions, etc. All locks are now given mode 0666.
* The old Descends-From attribute is now used as a parent. However,
it will NOT appear in these old project files. (This is one of
this history-changing modifications). It will appear in the output
of prcs info -l as another merge parent and be used for all other
common-parent related calculations.
** Changes since version 1.2.0b3
* Rekey and merge were using the umask for rewriting files,
causing them to change the file mode on occasion. A few other
file-mode related tweaks.
** Changes since version 1.2.0b2
* More autoconf/automake tweaks. No source modifications.
** Changes since version 1.2.0b1
* Upgrade to automake-1.1n, fixing problem with missing configure
file in the distribution. Use a workaround to include the man
page as well. No source modifications.
** Changes since version 1.1.1
* Output diff labels with correct version numbers, they were reversed.
Discovered by Klaus Weide.
* Make the configure script a little more user friendly. It will
detect the wrong versions of RCS and DIFF, and will report if
'prcs config' fails after a build.
* configure now accepts --disable-mmap, I tried reproducing a bug
I'd seen on HP-UX running across NFS, but I can't reproduce it,
so people who are concerned with using mmap can disable it.
* When merge moves a file into the "obsolete" subdirectory, it first
finds a unique name by appending ".~N~" until it finds a suitable
name, much like emacs with numbered backups turned on.
* The -j option wasn't partitioning jobs equally amongst its children
at certain stages of checkin, fixed.
* Very long comments in project files caused flex to abort stating
that it couldn't expand because of REJECT, except that it doesn't
use reject. Removing yylineno (and computing it myself) fixed
the problem.
* Implement the new command 'prcs depopulate'. This simple command
removes the file entries for each names file-or-dir, which as usual
defaults to all files (it queries you first, in this case).
* Implement the new command 'prcs admin pdelete' which deletes
a repository entry.
* Implement the new command 'prcs admin prename' which renames
a repository entry.
* New environment variable, PRCS_DIFF_OPTIONS, is a whitespace-
separated list of options to pass to diff during 'prcs diff'
and 'prcs merge'. If you need something with whitespace, you'll
have to pass it on the command line. Command line options override
PRCS_DIFF_OPTIONS.
* Fix bug causing initial checkin of the Nth file to fail if it has a
",v" extension and N%52==0. Discovered by Jesse Glick.
* Fix bug causing 'prcs populate -d' to delete more files than it
should. It now only prompts to delete files which were named on
the command line.
* Fix bug in behavior of merge case #8 (see the tutorial
http://www.xcf.berkeley.edu/~jmacd/merge.html), discovered
by Klaus Weide.
* Fix bug in recording of partial merges discovered out by Klaus
Weide. It was rotating the list of filenames in Merge-Parents
and New-Merge-Parents after each partial merge.
* Fix bug in presentation of query for case #8, it would be queried
twice and do nothing the first time. Only affects --skilled-merge.
Again, discovered by Klaus Weide.
* Fix the 'prcs admin access' command to work when run as root. It
will let you set users as well as groups when run as root.
* Implement new merge algorithm, described in the tutorial at
http://www.xcf.berkeley.edu/~jmacd/merge.html. This is not
yet documented in the texinfo documentation, nor is the texinfo
documentation updated for this version.
* Document the use of the TMPDIR environment variable.
** Changes since version 1.1.0
* Correct bug introduced in 1.1.0 causing project creation to fail
at initial checkin. How lame is that?
** Changes since version 1.1.0b5
* Checkin now reports adds and deletes properly. Behavior of '-l' at
checkin changed to only report modified, added, or deleted files.
'-L' gives old behavior. Changes reported are relative to the real
working version before checkin.
* configure now accepts --enable-debug to turn on compilation with
debugging symbols.
** Changes since version 1.1.0b4
* Update documentation to current sources.
* Add PRCS_JOB_NUMBER environment variable to set a default for the
-j option.
* Correct merge action when merging files with empty file descriptors.
* Correct selection of new version when checkin crosses major version
names. Not sure when this was broken.
** Changes since version 1.1.0b3
* Fix minor compilation trouble introduced in 1.1.0b, <sys/time.h>
is required to use setitimer().
* Fixed major bogon in the upgrade-repository code introduced in version
1.1.0b3. This only affects people attempting to upgrade a repository
older than version 1.1.0. This is not a dangerous problem, PRCS simply
core dumps without upgrading the repository.
** Changes since version 1.1.0b2
* Added a repository log which logs the details of the checkin,
rebuild, and delete commands. This is mostly here for the convenience
of trying to reconstruct the problem, should one occur.
** Changes since version 1.1.0b
* Checkin with partial merge asks whether to use the merge parent or
working version as the effective working version for checkin.
Checkin with --skilled-merge asks in either case.
* Fixed a bug in how partial merges work.
* Setup an alarm mechanism for refreshing locks during long
operations. Add SIGTSTP handler to warn user against suspending
PRCS for too long.
* Removed the optional USE_FCNTL_LOCKS locking code, I don't want
to maintain it.
** Changes since version 1.0.9
* Merge common-version algorithm changed to solve a problem pointed out
by Marco Antionotti.
When merging a set of working files against a selected version,
the common version must be computed. In previous versions of PRCS,
this was handled differently:
0.13.x and previous versions: the most recent merged-against version
was used or the working version if none exist.
1.0.0 through 1.0.9: the working version was used.
In each of these cases, differences arise only after one merge has
been completed and no checkin has been done. The algorithm used in
1.0.x failed to handle a very common case well, thus the new algorithm.
The very common case is this: version 0.1 is created, user A modifies
and checks in version 0.2. User B has 0.1 and merges against 0.2.
User A checks in 0.3. User B merges against 0.3. The common version
computed by 1.0.x is 0.1, which causes many conflicts caused by
re-merging in changes which have already been merged.
The new algorithm makes use of an "effective working version", which
is computed before the common version is computed. The effective working
version is used to compute the common version. If unique, the effective
working version is the version picked from the set of previous merge parents
and the working version which is closest to the calculated common version.
If not unique or the new option -s (--skilled-merge) is supplied, the user
is asked to pick a version manually. It is difficult to come up with a
situation requiring this intervention.
Normally PRCS prevents the same file from being merged twice, so that
merges can be interupted or aborted and later resumed. This can cause
difficulties for people who really know what they are doing and want
to force a merge to occur. The -s option also allows users to remerge
files.
* Arguments passed to diff3 changed: arguments were "-ma", and have
been changed to "-maE". The result is that only overlapping conflicts
are shown, not identical conflicts (where the file in both the selected
and working versions contain the same changes).
* New project-file entry Project-Keywords introduced. This allows the
definition of arbitrary keywords. These keywords are treated just
like the 13 builtin keywords and may be included in the special
$Format$ keyword directive. As an example, you can see these being
used to label release version numbers on the 3rd line of this file.
* Complete rewrite of the project-file reading and editing code and the
auxiliary data file code (.PROJECT.prcs_aux), it now uses much less
memory for large projects.
* Project renaming implemented. You may now renaming a project while
unpackaging. 'prcs unpackage' accepts an optional argument which
is used as the new project name. For example:
prcs unpackage P.pkg Q
unpackages the project contained in P.pkg (presumably named P) and
names it Q. The change affects the history of the project file
(it has been called Stalinesque) so that project files from old versions
checked out of Q will read as if their name were always Q. A comment
is inserted into the project files of old versions to remind the user
of the original name of the project when each particular version was
checked in. Renaming may only be performed on packages created by
prcs-1.1.0 and later, though prcs-1.1.0 and later will recognize the
old package format. Old versions of PRCS will not recognize new
packages.
* Another repository data format change was made, all projects will have
to be rebuilt with the 'prcs admin rebuild' command.
* Memory leak in flex buffer management found.
* texinfo3.7.patch no longer distributed, texinfo-3.9 fixes the problem.
* Return of the Digital UNIX binary (there was a bug in configure.in that
only was excited on machines at Berkeley mounting /usr/sww which was
making it difficult for me to build binaries).
NOTE: It appears that GNU rx-1.5 is not 64-bit clean, so until this
gets fixed the use of any regular expression functionality in PRCS
is likely to be broken. These include 'prcs populate' with a non-empty
Populate-Ignore attribute and 'prcs execute' with the --match or --not
options.
* Still no progress on HP-UX 10, looks to me as if gcc's fixincludes
is breaking stuff, cause the header files are seriously tweaked.
* Upgrade to autoconf-2.12, automake-1.1l, rx-1.5.
* GNU Copyright notices inserted in source files.
** Changes since version 1.0.0
* Repository directory layout changed to improve performance of large
projects. Formerly all files were kept in a flat directory structure,
now they are stored in a tree of subdirectories.
* -jN (--jobs=N) flag implemented to allow multiple processes during
checkin. Performance was evaluated for checkout and other commands
and not found to be worthwhile. Future vesions may include rewrites
to improve concurrency in other commands.
* The PRCS_CONFLICT_EDITOR environment variable was added as a _temporary_
means of allowing a user to edit a file immediately after conflicts
are created, during the merge. This will be more generalized in the
next major release of PRCS.
** Changes since version 1.0.8
* INSTALL modified, libg++-2.7.2 seems to be required for SGI IRIX
platforms.
* Repository compression was not affecting subdirectories in the repository,
this has been fixed.
** Changes since version 1.0.7
* Generation of unique filenames in the repository was broken.
This causes checkin to abort in certain cases with an message
stating that you've found a bug. You need not upgrade unless
you're experiencing this problem.
** Changes since version 1.0.6
* 'prcs rebuild' was broken since 1.0.4, this has been corrected.
Rebuild would fail on repositories which have had more than 50
files added with a PRCS version between 1.0.4 and 1.0.6.
** Changes since version 1.0.5b
* 'prcs rekey' was not preserving file modes, corrected.
* Forced checkin with no modified files was failing in new multi-job
checkin code.
** Changes since version 1.0.5a
* Compiles under HP-UX and AIX (problem caused their abnormally
screwed up select()).
** Changes since version 1.0.5
* Compiles under Solaris and IRIX. (problem caused by differently sized
pid_t and int types).
** Changes since version 1.0.4
* Fixed a bug in 'prcs info -L', reported by Gene Kan.
* Fixed a bug the MD5 checksum code causing certain digests to
be less than 128 bits (and thus differ from the output of another
md5 checksum generator). The unkeyed MD5 checksum of a file
is available with 'prcs info -L'.
* Added preliminary support for the -jN (--jobs=N) flag, which allows
PRCS to use up to N child processes. Currently -j is only implemented
for checkin.
** Changes since version 1.0.3
* Fixed a bug exposed by Linux libc 5.4.x, a bogus fclose() was being
called.
* Changed the repository directory structure to better handle
extremeley large projects.
** Changes since version 1.0.2
* 'prcs checkout -r.' was ignoring the working project file and
creating an empty project file.
* Add a PRCS_CONFLICT_EDITOR environment variable as a _temporary_
means of allowing a user to edit a file immediately after conflicts
are created, during the merge. Requested by Peter Mattis.
** Changes since version 1.0.1
* INSTALL modified, libg++-2.7.2 required for Digital UNIX platforms.
* Populate-Ignore was not working, corrected.
* Certain operations requiring creation of directory trees was failing
because PRCS was requiring all directories to be writable and
executable. This restriction was bogus, and has been relaxed, letting
those conditions in which a writable directory is required be caught.
** Changes since version 1.0.
* Change arguments passed to tar during unpackage to satisfy Sun's tar.
* Correct mkdir() call with trailing slash, which fails on old versions
of Linux.
* Replace <sys/fcntl.h> bogon in lock.h with <fcntl.h>.
* Correct behaviour of 'unpackage' on packagefiles not in CWD.
* Fix 2 bugs causing merged project files to become invalid either
at checkin or immediately after a merge.
