Version 3.81+dbg-0.3
2010-05-01

* Bug fixes
* Compiles on Solaris

Version 3.81+dbg-0.2 - Sam Woodward Release
2009-01-10

* Bug in trying to fake file information for a .PHONY target
* Some merge cleanup. Add debugger-specific documentation (from 3.80+dbg-0.61)

Version 3.81+dbg-0.1
2008-10-27	

* Merge in code from 3.80+dbg-0.63cvs. 
* Add "info rules" and "info vpath"

Version 3.80+dbg-0.63cvs
2006-04-01

* Add a "list" command. Basically same as "target x depends commands" 
  for now. "list -" shows the parent. 
* Help commands now show short usage.
* Ctrl-d leaves debugger 
* Add Emacs regression test and allow space in filename for MS Windows

Version 3.80+dbg-0.62
2007-02-27

* Changes to make more Debian compatibile. 
* Track some GNU Make 3.81 changes, which include a bugfix
  and making more strings "const". 
* Miscellaneous bugfixes

Version 3.80+dbg-0.61
2006-03-24

* Add comint shell tracking - taken from python's pdbtrack
* Add gdb's cd and pwd commands.
* "write" command now adds "cd <directory name>" as a comment.
* configure options:
   --with-default-shell to specify the default value
     for SHELL (useful on say Solaris), 
   --with-shell-trace to specify the option to turn on tracing, e.g. (-x).
* Add configure option --with-shell-trace to specify how to turn on
  tracing when running shell commands.
* Add --trace=normal. 
* run wasn't reading any (optional) arguments supplied.
* Guard against dereferencing NULL pointers.
* Some 3.81 features and bugfixes have been incorporated. At present
  not everything is there. 
* More doxygen documentation and docuementation improvements. Note
  debugger options in Manual page.

Version 3.80+dbg-0.60
2005-12-25

* On a fatal error we now show command arguments used to invoke
  program.
* tracing now sets shell tracing (+x) when invoking commands
* The default behavior on error is to show call trace. To turn off use
  --no-extended-errors. Recently added --extended-errors and -E (not in
  standard GNU Make) have been removed.
* "quit" can now terminate several levels of nested make (if "make"
  was called directly and not via a shell string).
* prompt now shows target and prerequisites.
* Fix bugs and memory leaks involving improper use of memory can weak
  casting.  (shown in the vpath regression test dash-I on cygwin).
* Reorganize help command. Is more ddd-friendly (and more gdb like).
* More explicit free's of memory at termination. 
* Give line numbers and target names on --just-print. Print delmiters
  around the commands.
* More debug tracing funnelled through db_level. Debugger command
  "show debug" shows the debug mask in a more understandable way.
* Incorporate patches from GNU/Linux make 3.80.
* Incorporate new functions from GNU Make 3.81: abspath, realpath, lastword
* Expand documentation.
* NOTE: the prompt has changed from "makedb" to "mdb" as has the 
  Emacs Lisp command name to run the debugger. This change was made to 
  avoid confusion between the Make debugger and a program which
  creates a DBM file. If you were using ddd-3.3.12-test.tar.gz you
  will need to get a newer version.

Version 3.80+dbg-0.5
2005-12-10 

* Errors in eval issued from the debugger no longer cause termination.
* Separation of "Step" and "Next. "Step" command granularity is now
  "Next". "Step" stepping is more fine grained.
* "target" command improvements:
   - sets file variables when showing is requested
   - add "target expand" to list target commands with "make" variables
     expanded.
   - allow @ or $@ as a target name 
* Add "info makefiles" to show what Makefiles have been read in.
* Add "info breakpoints"
* Breakpoints can now be listed and deleted by number - like gdb.
  This also helps ddd and should pave the way for more sophisticated
  kinds of breaking/watching.
* Add a number of aliases (e.g. backtrace, bt, !!, L)
  and via an internal alias mechanism
* Remove hash stats on printing variables -- generally not wanted for
  users (rather than GNU Make maintainers)
* Add explicit memory free and reduce reading uninitialized values.
* Revise testing mechanism for a more modern use of Perl. Can specify 
  test program file name (./scripts/variables/special) test name
  (variables/special). The former is works better with command
  completion. Document some more regression tests.
* Make build work outside of source tree. "make distcheck" doesn't bomb.
  It doesn't run the regression tests though :-(
* More documentation and doxygenization.
* Remove AMIGA support :-(

Version 3.80+dbg-0.4
2005-12-10 

* Add eval!
* Add ability to stop before reading Makefiles - may be useful in 
  debugging macros and variables --debugger=preread. We can now trace
  makefile reading activity with -d r or via --trace = {read,full}
* "where" command expanded to include above new Makefile read stack.
* Add call tracing.
* Fix bugs in showing automatic variables 
* Line number in Makefile commands is more accurate
* More ddd (gdb/bashdb) compatible: 
  - "help set" added 
  - "help show" works like the others
  - "info locals" added
  - "show command" (history) added
  - file/line reporting more like bash/perl
* write file takes basename of target file (well, at least for POSIX
  systems)
* Update documentation quite a bit
* Start to remove VMS support

Version 3.80+dbg-0.3

* tracing adds GNU Make "basic" debugging. If debugging, then we also
  enter the debugger read loop. Hopefully this adds more granularity
  but not the diarrhea that "make -d" gives. To reduce this, "next"
  could be used to skip over remaking targets that don't have
  commands.
* print and examine now show origin status
* print/examine work for automatic variables. examine still has 
  problems with automatic variables in strings though.
* Allow abbreviations of debugger command attributes. As a result some
  attributes were renamed slighly, e.g. vars -> variables, deps ->
  depends, cmds -> commands. But note that since substrings are
  allowed, "command" and "com", and even "c" is the same as
  "commands".
* Make option --trace (-x) overrules using the --silent option and
  not echoing @ commands.
* "list" command renamed to "target". A future "list" command will 
  look more like gdb.
* fixed compilation issue(s) on systems that have readline, but do not
  have termcap.
* fixed failure of enter_debugger to exit on an empty line from
  readline.
* install program as remake by default (not make).
* misc bug fixes and compilations fixes for various OS's


Version 3.80+dbg-0.2

* Add ability to print specified attributes of a target, e.g. "time",
  "deps", "vars"...
* Improve reporting target locations.
* Improve target stack tracking.
* Add "write" command - ability to write target commands to a file
  with MAKE variables expanded, or show that inside a debugger
  session.
* Separate info from show. Make these act more like they do in gdb
* Stay in debugger when a Makefile exits.
* First debugger documentation.

Version 3.80+dbg-0.1

Fork from version 3.80 

* New options
  --extended-errors (-E) call stack reporting, extended error reporting
  --trace (-x) gives tracing information before a command is run.

  execution
   step, next, continue, skip
   restart, quit, exit
