2012-01-16Update copyright notices.Paul Smith1-4/+4
2012-01-15Add GNU Guile as an optional embedded scripting language for make.Paul Smith1-3/+8
On configure-enabled systems, configure will detect Guile installed (using pkg-config, which is how GNU Guile is distributed) and enable it if so. On all non-configure-enabled systems, currently, the default is for Guile support to be disabled.
2011-11-15Enable jobserver on W32 when using configure.Paul Smith1-3/+4
Some W32 cleanups: see Savannah bug #34830 Forgot to modify the config.h.W32.template file for jobserver support.

Implementation contributed by Troy Runkel <Troy.Runkel@mathworks.com>

Don't do that. I couldn't come up with a repro case for this!

2010-07-09 job.c (pid2str) [WINDOWS32]: Don't use %Id with GCC < 4.x.Eli Zaretskii1-10/+12
(exec_command) [WINDOWS32]: Use pid2str instead of non-portable %Id. main.c (handle_runtime_exceptions): Use %p to print addresses, to DTRT on both 32-bit and 64-bit hosts. Savannah bug #27809. job.c (w32_kill, start_job_command, create_batch_file): Use pid_t for process IDs and intptr_t for the 1st arg of _open_osfhandle. function.c (windows32_openpipe): Use pid_t for process IDs and intptr_t for the 1st arg of _open_osfhandle. (func_shell): Use pid_t for process IDs. main.c (main) [WINDOWS32]: Pacify the compiler. config.h.W32.template (pid_t): Add a definition for 64-bit Windows builds that don't use GCC.

- Set up .FEATURES with separate calls for optional features, as some compilers don't like conditionals inside macro invocations.

it might be needed: for most situations we parse prereqs immediately as we used to. Reduces memory usage. - Fixes Savannah bug #18622.
2009-09-16- Add xcalloc() and call itPaul Smith1-7/+6
- Fix memory errors found by valgrind - Remove multi_glob() and empower parse_file_seq() to do its job: the goal here is to remove the confusing reverse/re-reverse we do on the file lists: needed for future fixes. - Add a prefix arg to parse_file_seq() - Make concat() variadic so it can take arbitrary #'s of strings

2007-11-04New special variable: .RECIPEPREFIXPaul Smith1-4/+5
Allows the user to reset the prefix character for introducing recipe lines from the default (tab) to any other single character, and back again. Also, reworked the manual to consistently use the word "recipe" to describe the set of commands we use to update a target, instead of the various phrases used in the past: "commands", "command lines", "command scripts", etc.

2007-05-09Fix Savannah bug #19656: rationalize our use of case-insensitive stringPaul Smith1-3/+3
comparison functions to always use POSIX strcasecmp(). For non-POSIX systems that use other functions (strcmpi or stricmp) use a macro to alias strcasecmp to those. If we can't find any of them (VMS, plus whatever UNIX doesn't have them) then define our own version in misc.c.
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.

Fix a file descriptor leak with make re-exec while using the jobserver. Update some release information.

Savannah bug #15182, but not much uses it yet. Coming shortly. - Added short-circuiting $(and ..) and $(or ...) functions.
2006-02-01Various updates, mainly to the Windows port, from Eli Zaretskii andPaul Smith1-7/+1
Markus Maurhart.
2006-01-04Various changes getting ready for the release of 3.81.Paul Smith1-2/+2
- Updates to make.texi and make.1 and other documentation - Some VMS patches - Fix minor bugs reported on the mailing list and from Debian.
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.
2005-08-08- Fixed a bug reported by Michael Matz regarding handling of parallelPaul Smith1-7/+14

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...
