[[3.1.18] [
After years of bjam developments.. This is going to be the last unbundled release of the
3.1.x series. From this point forward bjam will only be bundled as part of the larger
Boost Build system. And hence will likely change name at some point. As a side effect
of this move people will get more frequent release of bjam (or whatever it ends up being
called).
[list
[li New built-ins, MD5, SPLIT_BY_CHARACTERS, PRECIOUS, PAD, FILE_OPEN, and UPDATE_NOW.

[[3.1.17] [
A year in the making this release has many stability improvements and various performance
improvements. And because of the efforts of Jurko the code is considerably more readable!
[list
[li Reflect the results of calling bjam from Python.
-- ['Rene R.]
]
[li For building on Windows: Rework how arguments are parsed and tested to fix handling
of quoted arguments, options arguments, and arguments with "=".
-- ['Rene R.]
]
[li Try to work around at least one compiler bug with GCC and variable aliasing that
causes crashes with hashing file cache entries.
-- ['Rene R.]
]
[li Add -Wc,-fno-strict-aliasing for QCC/QNX to avoid the same aliasing crashes as in
the general GCC 4.x series (thanks to Niklas Angare for the fix).
-- ['Rene R.]
]
[li On Windows let the child bjam commands inherit stdin, as some commands assume
it's available.
-- ['Rene R.]
]
[li On Windows don't limit bjam output to ASCII as some tools output characters in
extended character sets.
-- ['Rene R.]
]
[li Isolate running of bjam tests to individual bjam instances to prevent possible
spillover errors from one test affecting another test. Separate the bjam used to run
the tests vs. the bjam being tested. And add automatic re-building of the bjam being
tested.
-- ['Rene R.]
]
[li Fix some possible overrun issues revealed by Fortify build. Thanks to Steven Robbins
for pointing out the issues.
-- ['Rene R.]
]
[li Handle \\n and \\r escape sequences.
-- ['Vladimir P.]
]
[li Minor edits to remove -Wall warnings.
-- ['Rene R.]
]
[li Dynamically adjust pwd buffer query size to allow for when PATH_MAX is default
defined instead of being provided by the system C library.
-- ['Rene R.]
]
[li Minor perf improvement for bjam by replacing hash function with faster version. Only
1% diff for Boost tree.
-- ['Rene R.]
]
[li Updated Boost Jam's error location reporting when parsing Jamfiles. Now it reports
the correct error location information when encountering an unexpected EOF. It now
also reports where an invalid lexical token being read started instead of finished
which makes it much easier to find errors like unclosed quotes or curly braces.
-- ['Jurko G.]
]
[li Removed the -xarch=generic architecture from build.jam
as this option is unknown so the Sun compilers on Linux.
-- ['Noel B.]
]
[li Fixed a bug with T_FATE_ISTMP getting reported as T_FATE_ISTMP & T_FATE_NEEDTMP at
the same time due to a missing break in a switch statement.
-- ['Jurko G.]
]
[li Fixed a Boost Jam bug causing it to sometimes trigger actions depending on targets
that have not been built yet.
-- ['Jurko G.]
]
[li Added missing documentation for Boost Jam's :T variable expansion modifier which
converts all back-slashes ('\\') to forward slashed ('/').
-- ['Jurko G.]
]
[li Added Boost Jam support for executing command lines longer than 2047 characters (up
to 8191) characters when running on Windows XP or later OS version.
-- ['Jurko G.]
]
[li Fixed a Boost Jam bug on Windows causing its SHELL command not to work correctly with
some commands containing quotes.
-- ['Jurko G.]
]
[li Corrected a potential memory leak in Boost Jam's builtin_shell() function that would
appear should Boost Jam ever start to release its allocated string objects.
-- ['Jurko G.]
]
[li Made all Boost Jam's ECHO commands automatically flush the standard output to make
that output more promptly displayed to the user.
-- ['Jurko G.]
]
[li Made Boost Jam tests quote their bjam executable name when calling it allowing those
executables to contain spaces in their name and/or path.
-- ['Jurko G.]
]
[li Change execunix.c to always use fork() instead of
vfork() on the Mac. This works around known issues
with bjam on PPC under Tiger and a problem reported
by Rene with bjam on x86 under Leopard.
-- ['Noel B.]
]
[li Corrected a bug in Boost Jam's base Jambase script causing it to trim the error
message displayed when its boost-build rule gets called multiple times.
-- ['Jurko G.]
]
[li When importing from Python into an module with empty string as name,
import into root module.
-- ['Vladimir P.]
]
[li Patch for the NORMALIZE_PATH builtin Boost Jam rule as well as an appropriate update
for the path.jam Boost Build module where that rule was being used to implement path
join and related operations.
-- ['Jurko G.]
]
[li Fixed a bug causing Boost Jam not to handle target file names specified as both short
and long file names correctly.
-- ['Jurko G.]
]
[li Relaxed test, ignoring case of drive letter.
-- ['Roland S.]
]
[li Implemented a patch contributed by Igor Nazarenko reimplementing the list_sort()
function to use a C qsort() function instead of a hand-crafted merge-sort algorithm.
Makes some list sortings (e.g. 1,2,1,2,1,2,1,2, \.\.\.) extremely faster, in turn
significantly speeding up some project builds.
-- ['Jurko G.]
]
[li Fixed a bug with bjam not handling the '\' root Windows path correctly without its
drive letter being specified.
-- ['Jurko G.]
]
[li Solved the problem with child process returning the value 259 (Windows constant
STILL_ACTIVE) causing bjam never to detect that it exited and therefore keep running
in an endless loop.
-- ['Jurko G.]
]
[li Solved the problem with bjam going into an active wait state, hogging up processor
resources, when waiting for one of its child processes to terminate while not all of
its available child process slots are being used.
-- ['Jurko G.]
]
[li Solved a race condition between bjam's output reading/child process termination
detection and the child process's output generation/termination which could have
caused bjam not to collect the terminated process's final output.
-- ['Jurko G.]
]
[li Change from vfork to fork for executing actions on Darwin to improve stability.
-- ['Noel B.]
]
[li Code reformatting and cleanups.
-- ['Jurko G.]
]
[li Implement ISFILE built-in.
-- ['Vladimir P.]

[list
[li Work around some Windows CMD.EXE programs that will fail executing a totally
empty batch file.

[li Fix buffer overrun bug in expanding [^@()] subexpressions.
-- ['Rene R.]

[li Check empty string invariants, instead of assuming all strings are allocated.
And reset strings when they are freed.
-- ['Rene R.]
]
[li Add [^OSPLAT=PARISC] for HP-UX PA-RISC.
-- ['Boris G.]
]
[li Make quietly actions really quiet by not printing the command output. The
output for the quietly actions is still available through =__ACTION_RULE__=.
-- ['Rene R.]
]
[li Switch intel-win32 to use static multi thread runtime since the single
thread static runtime is no longer available.
-- ['Rene R.]
]
[li When setting =OSPLAT=, check =__ia64= macro.

around the CMD shell using [^=] as an argument separator.
-- ['Rene R.]

[li Add values of variables specified with -s to .EVNRION
module, so that we can override environment on
command line.
-- ['Vladimir P.]
]
[li Make NORMALIZE_PATH convert \\ to /.

[[3.1.15] [
This release sees a variety of fixes for long standing Perforce/Jam problems. Most of
them relating to running actions in parallel with the -jN option. The end result of the
changes is that running parallel actions is now reliably possible in Unix and Windows
environments. Many thanks to Noel for joining the effort, to implement and fix the Unix
side of stuff.
[list
[li Add support for building bjam with pgi and pathscale toolsets.
-- ['Noel B.]
]
[li Implement running action commands through pipes (-p option) to fix jumbled
output when using parallel execution with -j option. This is implemented
for Unix variants, and Windows (Win32/NT).
-- ['Rene R.], ['Noel B.]
]
[li Add "sun" as alias to Sun Workshop compiler tools.
-- ['Rene R.]
]
[li Set MAXLINE in jam.h to 23k bytes for AIX. The piecemeal archive action
was broken with the default MAXLINE of 102400. Because the AIX shell uses
some of the 24k default buffer size for its own use, I reduced it to 23k.
-- ['Noel B.]
]
[li Make use of output dir options of msvc to not polute src dir with compiled files.
-- ['Rene R.]
]
[li A small fix, so -d+2 will always show the "real" commands being executed
instead of casually the name of a temporary batch file.
-- ['Roland S.]
]
[li Add test to check 'bjam -n'.
-- ['Rene R.]
]
[li Add test to check 'bjam -d2'.
-- ['Rene R.]
]
[li Bring back missing output of -n option. The -o option continues to be
broken as it has been for a long time now because of the @ file feature.
-- ['Rene R.]
]
[li Update GC support to work with Boehm GC 7.0.
-- ['Rene R.]
]
[li Revert the BOOST_BUILD_PATH change, since the directory passed to
boost-build should be first in searched paths, else project local
build system will not be picked correctly. The order had been changed to
allow searching of alternate user-config.jam files from boost build. This
better should be done with --user-config= switch or similar.
-- ['Roland S.]
]
[li Initial support for defining action body from Python.
-- ['Vladimir P.]
]
[li Implement @() expansion during parse phase.
-- ['Rene R.]
]
[li Define OSPLAT var unconditionally, and more generically, when possible.
-- ['Rene R.]
]
[li Fix undeclared INT_MAX on some platforms, i.e. Linux.
-- ['Rene R.]
]
[li Modified execunix.c to add support for terminating
processes that consume too much cpu or that hang and
fail to consume cpu at all. This in support of the
bjam -lx option.
-- ['Noel B.]
]
[li Add internal dependencies for multi-file generating actions to indicate
that the targets all only appear when the first target appears. This fixes
the long standing problem Perforce/Jam has with multi-file actions and
parallel execution (-jN).
-- ['Rene R.]
]
[li Add test of -l limit option now that it's implemented on windows and unix.
-- ['Rene R.]
]
[li Add test for no-op @() expansion.
-- ['Rene R.]
]
[li Handle invalid formats of @() as doing a straight substitution instead of
erroring out.
-- ['Rene R.]
]
[li Various fixes to compile on SGI/Irix.
-- ['Noel B.]
]
[li Add output for when actions timeout with -lN option.
-- ['Rene R.], ['Noel B.]
]
[li Add needed include (according to XOPEN) for definition of WIFEXITED and WEXITSTATUS.
-- ['Markus S.]
