2013-06-22Fix a fatal error at startup on Windows due to non-ASCII characters in PATH.Eli Zaretskii1-9/+12
main.c (find_and_set_default_shell): Don't use file_exists_p or dir_file_exists_p, as those call readdir, which can fail if PATH includes directories with non-ASCII characters, and that would cause Make to fail at startup with confusing diagnostics. See https://sourceforge.net/mailarchive/message.php?msg_id=30846737 for the details.
2013-06-22Create a character map to use for locating stop-points in strings.Paul Smith1-2/+46
In various places we were passing flags and characters to compare, then using complex conditionals to see where to stop in string searches. Performance numbers reveal that we were spending as much as 23% of our processing time in these functions, most of it in the comparison lines. Instead create a character map and use a single bitwise comparison to determine if this is any one of the stop characters.
2013-06-21Disable database verification unless debug enabled.Paul Smith1-40/+47
The database verification can take a long time. Only enable it if debug mode is enabled. If MAKE_MAINTAINER_MODE is set, it's also enabled by default.

2013-05-26[SV #39028] Fix some small typos in messages.Paul Smith1-1/+1
2013-05-22Force version printing whenever we print the database.Paul Smith1-3/+4
2013-05-22Make MFLAGS and MAKEFLAGS more reliable and predictable.Paul Smith1-115/+80
Ensure all simple flags are kept in the initial batch of flags. Do not allow any flags with options in that batch. If there are only non-simple flags ensure MAKEFLAGS begins with " ". Don't let MFLAGS start with "- ".
2013-05-17Fix MS-Windows compilation when OUTPUT_SYNC is not defined.Eli Zaretskii1-0/+4
main.c (prepare_mutex_handle_string): Define conditioned on OUTPUT_SYNC.
2013-05-17Update source file format: remove TABs, use GNU coding styles.Paul Smith1-133/+149

2013-05-13[Savannah #20501] Handle adding -r/-R to MAKEFLAGS in the makefile.Paul Smith1-4/+24
If -R is set in the makefile and not the command line, then go through all the default variables and undefine them. If -r is set in the makefile and not in the command line, then remove all .SUFFIX prefixes (unless the user set it) and SUFFIX variable setting. In -p mode don't print builtins.
2013-05-13Add a new variable: GNUMAKEFLAGSPaul Smith1-0/+3
This allows you to write portable makefiles that set GNU make-specific command line options in the environment or makefile: add them to GNUMAKEFLAGS instead of MAKEFLAGS and they will be seen by GNU make but ignored by other implementations of make.
2013-05-13Use level o_env_override for MAKEFLAGS so it's reset even with -e.Paul Smith1-7/+7
Fixes Savannah bug #2216.
2013-05-13Add new --trace[=MODE] flags, with --trace=dirPaul Smith1-5/+35
This mode replaces the previous heuristic setting enabled with -O, where we would log directory enter/leave for each synchronized output. Now we only do that if --trace=dir is given.

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.

Implementation contributed by Troy Runkel <Troy.Runkel@mathworks.com>
2011-11-14In very obscure situations we may write the free token back to the pipe.Paul Smith1-1/+2
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.

2010-07-06- Enhance .POSIX to set -e when invoking shells, as demanded by aPaul Smith1-10/+11
backward-incompatible change in the 2008 POSIX specification. - Add the .SHELLFLAGS variable so people can choose their own shell flags. - Add tests for this. - Add documentation for this.
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.
