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.
- Add support for building bjam with pgi and pathscale toolsets. -- Noel
B.
- 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.
- Add "sun" as alias
to Sun Workshop compiler tools. -- Rene R.
- 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.
- Make use of output dir options of msvc to not polute src
dir with compiled files. -- Rene R.
- 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.
- Add test to check 'bjam -n'. -- Rene R.
- Add test to
check 'bjam -d2'. -- Rene R.
- 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.
- Update GC support to work with Boehm GC 7.0. -- Rene R.
- 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.
- Initial support for defining action body from Python. -- Vladimir
P.
- Implement @() expansion during parse phase. -- Rene
R.
- Define OSPLAT var unconditionally, and more generically,
when possible. -- Rene R.
- Fix undeclared INT_MAX on
some platforms, i.e. Linux. -- Rene R.
- 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.
- 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.
- Add test of -l limit option now that it's implemented on
windows and unix. -- Rene R.
- Add test for no-op @()
expansion. -- Rene R.
- Handle invalid formats of @()
as doing a straight substitution instead of erroring out. -- Rene
R.
- Various fixes to compile on SGI/Irix. -- Noel B.
- Add output for when actions timeout with -lN option. -- Rene
R., Noel B.
- Add needed include (according
to XOPEN) for definition of WIFEXITED and WEXITSTATUS. -- Markus
S.
