2005-05-03Fix problems with losing tokens in the jobserver, reported by GrantPaul Smith1-13/+10
Taylor. There are two forms of this: first, it was possible to lose tokens when using -j and -l at the same time, because waiting jobs were not checked when determining whether any jobs were outstanding. Second, if you had an exported recursive variable that contained a $(shell ...) function there is a possibility to lose tokens, since a token was taken but the child list was not updated until after the shell function was complete. To resolve this I introduced a new variable that counted the number of tokens we have obtained, rather than checking whether there were any children on the list. I also added some sanity checks to make sure we weren't writing back too many or not enough tokens. And, the master make will drain the token pipe before exiting and compare the count of tokens at the end to what was written there at the beginning. Also: * Ensure a bug in the environment (missing "=") doesn't cause make to core. * Rename the .DEFAULT_TARGET variable to .DEFAULT_GOAL, to match the terminology in the documentation and other variables like MAKECMDGOALS. * Add documentation of the .DEFAULT_GOAL special variable. Still need to document the secondary expansion stuff...
2005-04-13Fix performance degradation introduced by the second expansion feature.Paul Smith1-27/+38
I did this by adding intelligence into the algorithm such that the second expansion was only actually performed when the prerequisite list contained at least one "$", so we knew it is actually needed. Without this we were using up a LOT more memory, since every single target (even ones never used by make) had their file variables initialized. This also used a lot more CPU, since we needed to create and populate a new variable hash table for every target. There is one issue remaining with this feature: it leaks memory. In pattern_search() we now initialize the file variables for every pattern target, which allocates a hash table, etc. However, sometimes we recursively invoke pattern_search() (for intermediate files) with an automatic variable (alloca() I believe) as the file. When that function returns, obviously, the file variable hash memory is lost.

2004-09-21Some code cleanups and efficiency enhancements. As far as I can tellPaul Smith1-32/+28
none of these have impacts that are visible to the user (although in some cases that appears to be nothing more than dumb luck :-/).
2004-09-21Fix some bugs in variable pattern substitution (e.g. $(VAR:A=B)),Paul Smith1-2/+2
reported by Markus Mauhart <qwe123@chello.at>. One was a simple typo; to fix the other we call patsubst_expand() for all instances of variable substitution, even when there is no '%'. We used to call subst_expand() with a special flag set in the latter case, but it didn't work properly in all situations. Easier to just use patsubst_expand() since that's what it is.
2004-05-16Various enhancementsPaul Smith1-5/+3
- OS/2 Patches - OpenVMS updates - Sanitize the handling of -include/sinclude with and without -k - Fix the setting of $< for order-only rules.
2004-03-22Numerous updates and bug fixes.Paul Smith1-1/+1
A number of W32 cleanups from J.Grant. A number of OS/2 cleanups from Andreas Buening. Various random bug fixes.
2004-01-21Many bug fixes etc.Paul Smith1-21/+24
- Apply a fix for the "thundering herd" problem when using "-j -l". This also fixes bug #4693. - Fix bug #7257: allow functions as ifdef arguments - Fix bug #4518: make sure we print all double-colon rules with -p. - Upgrade to autconf 2.58/automake 1.8/gettext 0.13.1 - Various doc cleanups, etc.

- Fix some uncleanliness about the implementation of patterns-specific vars. - Some enhancements to the OS/2 port.
2003-03-24Add support for OS/2, contributed by Andreas Buening <andreas.buening@nexgo.de>Paul Smith1-4/+8
Also a small patch from Hartmut Becker <Hartmut.Becker@compaq.com> for VMS.
2003-01-30Fix bug #2238: the read.c:eval() function was not entirely reentrant.Paul Smith1-7/+11
Apply patch #1022: fix a memory corruption on very long target-specific variable definition lines.
2003-01-30Portability fix for glob.h building in FreeBSD ports system.Paul Smith1-4/+10
Implement a fix for bug # 2169: too many OSs, even major OSs like Solaris, don't properly implement SA_RESTART: important system calls like stat() can still fail when SA_RESTART is set. So, forget the BROKEN_RESTART config check and get rid of atomic_stat() and atomic_readdir(), and implement permanent wrappers for EINTR checking on various system calls (stat(), fstat(), opendir(), and readdir() so far).
2002-10-25Fix eval bugs 1516 and 1517.Paul Smith1-17/+38
2002-10-14Convert the source code to use ANSI C style function definitions andPaul Smith1-75/+27
enable the automake ansi2knr capability. Right now this doesn't quite build using a K&R compiler because of a problem with the loadavg test program, but the rest of the code works. I'm asking the automake list about this problem.
2002-10-13Fix bug#1379: don't use alloca() where it could overrun the stack size.Paul Smith1-9/+22
Implemented enhancement #1391: allow "export" in target-specific variable definitions. Change the Info name of the "Automatic" node to "Automatic Variables". Add text clarifying the scope of automatic variables to that section.
2002-10-05Fix core dump on malformed variable line (Debian bug #81656)Paul Smith1-10/+13

2002-08-10Update to a new version of automake and gettext.Paul Smith1-20/+20
Invent a new macro HAVE_DOS_PATHS and change various instances of: #if defined(WINDOWS) || defined(__MSDOS__) to use the new macro instead. This should help make the OS/2 port cleaner, as well. Invent a cvs-clean maintainer target that tries to get the workspace back to the state it was in after a CVS checkout. New language.

2002-07-08Various cleanups reported by people using the alpha release.Paul Smith1-4/+29
Incorporate "order-only" prerequisites patch. Wrote a test for it. The test shows what might be a bug in the code; I need to look at it more closely (anyway it doesn't behave as I expected). Also I haven't done the docs yet.
