2013-05-05Rename the -O "job" mode to "line" and "make" to "recurse".Paul Smith1-7/+7
2013-04-28Add support for per-job output sync.Paul Smith1-1/+5
A new flag to the -O/--output-sync, "job", selects a per-job (that is, per line of a recipe) output synchronization. To support this move the close of the temp file out of the sync_output() function and don't do it until we free the child, since we may call sync_output() multiple times in a given recipe. When we set up for a new temp file, if we're in per-job mode we truncate the file and seek to the beginning to re-use it for every job.
2013-04-27Support --output-sync on MS-Windows.Eli Zaretskii1-0/+47
w32/compat/posixfcn.c: New file, with emulations of Posix functions and Posix functionality for MS-Windows. w32/subproc/sub_proc.c: Include io.h. (process_noinherit): New function, forces a file descriptor to not be inherited by child processes. (process_easy): Accept two additional arguments, and use them to set up the standard output and standard error handles of the child process. w32/include/sub_proc.h (process_easy): Adjust prototype. (process_noinherit): Add prototype. read.c [WINDOWS32]: Include windows.h and sub_proc.h. makeint.h (LOCALEDIR) [WINDOWS32}: Define to NULL if not defined. This is needed because the MS-Windows build doesn't have a canonical place for LOCALEDIR. (WIN32_LEAN_AND_MEAN) [WINDOWS32]: Define, to avoid getting from windows.h header too much stuff that could conflict with the code. main.c <sync_mutex>: New static variable. <switches>: Add support for "--sync-mutex" switch. (decode_output_sync_flags): Decode the --sync-mutex= switch. (prepare_mutex_handle_string) [WINDOWS32]: New function. (main): Add "output-sync" to .FEATURES. job.h (CLOSE_ON_EXEC) [WINDOWS32]: Define to call process_noinherit. (F_GETFD, F_SETLKW, F_WRLCK, F_UNLCK, struct flock) [WINDOWS32]: New macros. (RECORD_SYNC_MUTEX): New macro, a no-op for Posix platforms. (sync_handle_t): New typedef. job.c <sync_handle>: Change type to sync_handle_t. (FD_NOT_EMPTY): Seek to the file's end. Suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>. (pump_from_tmp_fd) [WINDOWS32]: Switch to_fd to binary mode for the duration of this function, and then change back before returning. (start_job_command) [WINDOWS32]: Support output_sync mode on MS-Windows. Use a system-wide mutex instead of locking stdout/stderr. Call process_easy with two additional arguments: child->outfd and child->errfd. (exec_command) [WINDOWS32]: Pass two additional arguments, both -1, to process_easy, to adjust for the changed function signature. function.c (windows32_openpipe) [WINDOWS32]: This function now returns an int, which is -1 if it fails and zero otherwise. It also calls 'error' instead of 'fatal', to avoid exiting prematurely. (func_shell_base) [WINDOWS32]: Call perror_with_name if windows32_openpipe fails, now that it always returns. This avoids a compiler warning that error_prefix is not used in the MS-Windows build. config.h.W32.template (OUTPUT_SYNC): Define. build_w32.bat: Add w32/compat/posixfcn.c to compilation and linking commands. From Frank Heckenbach <f.heckenbach@fh-soft.de>: job.c (sync_output): Don't discard the output if acquire_semaphore fails; instead, dump the output unsynchronized.

Based on work by David Boyce <David.S.Boyce@gmail.com>.
2013-02-25Expand the loadable object support.Paul Smith1-1/+1
Provide a simple API for loaded objects to interact with GNU make. I still won't guarantee that this API won't change but it's much closer to something that's supported and provides easy-to-use interfaces with a public header file.
2013-01-20Rename the make.h file to makeint.h for internal use only.Paul Smith1-1/+1
2013-01-20Allow dynamically loaded objects to be rebuilt by make.Paul Smith1-591/+591

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.

Don't do that. I couldn't come up with a repro case for this!
2011-09-18When we re-exec the master makefile in a jobserver environment, ensurePaul Smith1-3/+5
that MAKEFLAGS is set properly so the re-exec'd make runs in parallel. See Savannah bug #33873.

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. Savannah bug #27809. Patch by Ozkan Sezer <sezeroz@gmail.com>
2010-07-06- Enhance .POSIX to set -e when invoking shells, as demanded by aPaul Smith1-10/+11

2010-07-01- Add whitespace to command line invocation in features/recursionPaul Smith1-7/+16
- Set up .FEATURES with separate calls for optional features, as some compilers don't like conditionals inside macro invocations.

2009-09-24- Rework secondary expansion so we only defer it if there's a possibilityPaul Smith1-2/+1
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.
2007-07-04* Update to GPLv3Paul Smith1-15/+15
* Update copyright to 2007 * Fix download URL for translation files (thanks to Thiemo Seufer)
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.
2006-04-07Code cleanup: Remove all references to PARAMS() & ansi2knr.Paul Smith1-23/+23
2006-03-20Add some alloca(0) calls for systems without "normal" alloca support.Paul Smith1-43/+55
Fix a file descriptor leak with make re-exec while using the jobserver. Update some release information.
