2007-03-20This is a major update, which switches virtually every allocated-but-not-freedPaul Smith1-82/+95
string into the strcache. As a side-effect, many more structure members and function arguments can/should be declared const. As mentioned in the changelog, unfortunately measurement shows that this change does not yet reduce memory. The problem is with secondary expansion: because of this we store all the prerequisites in the string cache twice. First we store the prerequisite string after initial expansion but before secondary expansion, then we store each individual file after secondary expansion and expand_deps(). I plan to change expand_deps() to be callable in either context (eval or snap_deps) then have non-second-expansion targets call expand_deps() during eval, so that we only need to store that dependency list once.
2006-11-18Fix from Eli for incorrect value of $(MAKE) on Cygwin.Paul Smith1-54/+62
A few changes from char* to void* where appropriate, and removing of unnecessary casts. Much more work on const-ifying the codebase. This round involves some code changes to make it correct. NOTE!! There will almost certainly be problems on the non-POSIX ports that will need to be addressed after the const changes are finished: they will need to be const-ified properly and there may need to be some changes to allocate memory, etc. as well. The next (last?) big push for this, still to come, is const-ifying the filenames in struct file, struct dep, etc. This will allow us to store file names in the string cache and finally resolve Savannah bug #15182 (make uses too much memory), among other advantages.
2006-04-09Another round of cleanups:Paul Smith1-151/+158
- Add more warnings. - Rename variables that mask out-scope vars with the same name. - Remove all casts of return values from xmalloc, xrealloc, and alloca. - Remove casts of the first argument to xrealloc. - Convert all bcopy/bzero/bcmp invocations to use memcp/memmove/memset/memcmp.

2005-10-24Make second expansion optional (partial implementation).Paul Smith1-1/+8
I decided this feature was too impacting to make the permanent default behavior. This set of changes makes the default behavior of make the old behavior (no second expansion). If you want second expansion, you must define the .SECONDEXPANSION: special target before the first target that needs it. This set of changes ONLY fixes explicit and static pattern rules to work like this. Implicit rules still have second expansion enabled all the time: I'll work on that next. Note that there is still a backward-incompatibility: now to get the old SysV behavior using $$@ etc. in the prerequisites list you need to set .SECONDEXPANSION: as well.

2005-07-04Various fixes and updates from testers of the beta3 release (mostly WindowsPaul Smith1-10/+6
and OS/2 changes).
2005-06-27Fix strerror() handling for systems which set ANSI_STRING.Paul Smith1-1/+1
Don't print errors if "include" is specified with no arguments. New test suite for the $(shell ...) function.
2005-06-25Fix -W foo yielding infinite recursion in some cases of re-exec.Paul Smith1-4/+14
Added a -W test suite.
2005-06-25Add a new variable: MAKE_RESTARTS, to count how many times make has re-exec'd.Paul Smith1-44/+76
When rebuilding makefiles, unset -B if MAKE_RESTARTS is >0.
2005-06-12Fix Savannah bug # 1328: if stdout is redirected to a full filesystem, wePaul Smith1-0/+5
check for this and exit with an error. The closeout.c version from gnulib pulls in too much other stuff, and gnulib requires an ANSI C 89 compliant compiler, while GNU make (so far) still wants to work on K&R.
2005-05-08Document the secondary expansion method. Also, some other documentationPaul Smith1-8/+24
cleanups. If we find a make error (invalid makefile syntax or something like that) write back any tokens we have before we exit. If we have waiting jobs (using -j + -l) set an alarm before we sleep on the read() system call, so we can wake up to check the load and start waiting jobs, if there are long-running jobs we would otherwise be waiting for. Suggested by Grant Taylor.
2005-05-03Fix problems with losing tokens in the jobserver, reported by GrantPaul Smith1-14/+42
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 $(shell ...) function there is a possibility to lose tokens, since a token was taken but the child list was not updated until after the shell function was complete. To resolve this I introduced a new variable that counted the number of tokens we have obtained, rather than checking whether there were any children on the list. I also added some sanity checks to make sure we weren't writing back too many or not enough tokens. And, the master make will drain the token pipe before exiting and compare the count of tokens at the end to what was written there at the beginning. Also: * Ensure a bug in the environment (missing "=") doesn't cause make to core. * Rename the .DEFAULT_TARGET variable to .DEFAULT_GOAL, to match the terminology in the documentation and other variables like MAKECMDGOALS. * Add documentation of the .DEFAULT_GOAL special variable. Still need to document the secondary expansion stuff...
2005-04-13Fix performance degradation introduced by the second expansion feature.Paul Smith1-0/+2
I did this by adding intelligence into the algorithm such that the second expansion was only actually performed when the prerequisite list contained at least one "$", 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.

2004-11-29Fix bug #10252: Remove any trailing slashes from -C arguments (WINDOWS32).Paul Smith1-3/+14
Add a regression test for "@" before a define/enddef vs. one inside.
2004-11-28Fix for bug #1276: Handle SHELL according to POSIX requirements.Paul Smith1-16/+27
POSIX requires that the value of SHELL in the makefile NOT be exported to sub-commands. Instead, the value in the environment when make was invoked should be passed to the environment of sub-commands. Note that make still uses SHELL to _run_ sub-commands; it just doesn't change the value of the SHELL variable in the environment of sub-commands. As an extension to POSIX, if the makefile explicitly exports SHELL then GNU make _will_ use it in the environment of sub-commands.
2004-11-28Fix WINDOWS32 bug #11155 with patch from Alessandro Vesely.Paul Smith1-4/+7

This commits a number of changes from Earnie Boyd that allows GNU make to build for MINGW32 systems.

2002-10-14Convert the source code to use ANSI C style function definitions andPaul Smith1-45/+25
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.
2002-08-10Update to a new version of automake and gettext.Paul Smith1-4/+4
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.
