2013-05-17Update for GNU make release candidate 3.99.90.3.99.90Paul Smith4-4/+8
2013-05-17Update source file format: remove TABs, use GNU coding styles.Paul Smith36-3304/+3348
2013-05-17Update copyright for changes in 2013.Paul Smith100-101/+118
2013-05-17Use xcalloc() in hash.c to handle out of memory errors.Paul Smith2-1/+3
2013-05-17Remove the dlopen() pointer from struct filedef.Paul Smith7-25/+79
This pointer is almost never needed, and it increases the size of the filedef struct for all files (of which there are a huge number for large builds). Instead keep a bit field marking whether the file is a loaded object and if so call a new function to unload it. In load.c we keep a simple linked list of loaded objects (of which there will be very few typically) and their dlopen() pointers.
2013-05-14Add requirement for plugin_is_GPL_compatible symbol in loaded objects.Paul Smith6-0/+41
2013-05-13[Savannah #20501] Handle adding -r/-R to MAKEFLAGS in the makefile.Paul Smith7-37/+97
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 Smith5-6/+62
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 Smith3-21/+21
Fixes Savannah bug #2216.
2013-05-13Add new --trace[=MODE] flags, with --trace=dirPaul Smith9-36/+102
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.
2013-05-11Avoid printing stdout and stderr messages without a newline between them.Eli Zaretskii2-1/+7
job.c (child_out): Output the newline following the message before fllush-ing the stream. Avoids displaying the following failure message, which goes to stderr, on the same line.
2013-05-06Rearrange dllimport/dllexport declarations for MS-Windows.Eli Zaretskii3-4/+12
gnumake.h (GMK_EXPORT) [_WIN32]: Move the dllexport declaration here from makeint.h. makeint.h (GMK_BUILDING_MAKE) [WINDOWS32]: Define before including gnumake.h.

Enabling 'subdir-objects' would require sublter changes to several other parts of the build system that I don't know how to test properly. We should only enable the 'silent-rules' option for the moment. The updated patch below does this.

2013-05-06build: require Autoconf >= 2.62 and Automake >= 1.11.1Stefano Lattarini2-3/+17
Older versions of those tools should be considered fully obsolete. Also, GNU make already requires Gettext >= 0.18.1, which has been released six months after Automake 1.11.1 and two years after Autoconf 2.62; so the new requirement shouldn't be problematic for people already bootstrapping GNU make from the Git repository. * configure.ac (AC_PREREQ): Require Autoconf 2.62 or later. (AM_INIT_AUTOMAKE): Require Automake 1.11.1 or later (1.11 had some serious bugs, and should not be used).

2013-05-06Remove use of vfork().Paul Smith7-42/+6
GCC was giving us warnings, most OS's now just run fork() when you call vfork(), and looking at the standard definition of vfork() we are a long way from using it safely anyway: you're not allowed to even call a function before you exec().

2013-05-05build: get rid of 'HAVE_ANSI_COMPILER' C preprocessor conditionalStefano Lattarini6-18/+13
GNU make already assume C89 or later throughout the codebase, and that preprocessor conditional was no longer used anyway. * configure.ac: Remove AC_DEFINE of HAVE_ANSI_COMPILER. * config.ami.template: Remove #define of HAVE_ANSI_COMPILER. * config.h-vms.template: Likewise. * config.h.W32.template: Likewise. * configh.dos.template: Likewise.

2013-05-05Rename the -O "job" mode to "line" and "make" to "recurse".Paul Smith8-55/+81
2013-05-05Ensure command lines are written synchronously with -O.Paul Smith5-100/+96
If output-sync is enabled, have make write the command line to the temp file instead of printing it directly to the screen to ensure that the output is ordered properly. Also, remove extraneous enter/leave operations by having them printed directly when dumping temp file output.
2013-05-04Add memory allocation cleanup to loadable objects.Paul Smith7-20/+159
Add gmk_alloc() and gmk_free() functions so loadable objects can access our memory model. Also provide a more extensive example in the manual.

2013-05-04Improve sync handling for -Ojob/-Otarget and recursion.Paul Smith5-131/+183
If we are not going to sync a command line then dump any collected output first to preserve ordering. Do some code cleanup: * Move the handle init to a separate function. * Move the temp file truncation to the output function. * Remember whether we sync in a variable for readability. * Handle EINTR and short writes in child_out(). * Always call sync_output() in case output_sync was changed due to error.
2013-05-04Fix a typo in the manual.Eli Zaretskii1-1/+1
2013-05-04Fix a possibly confusing comment at end of pump_from_tmp_fd.Eli Zaretskii1-1/+2
2013-05-04Fix the MS-Windows branch of output_sync code.Eli Zaretskii2-2/+7
job.c (start_job_command): Make the condition for creating a temporary output file be identical to the Posix code branch. Suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.
2013-05-03Fix invocation of Windows batch files with whitespace in their names.Eli Zaretskii2-3/+55
w32/subproc/sub_proc.c: Include makeint.h. Remove a private incompatible prototype of xmalloc. (batch_file_with_spaces): New function, detects Windows batch files whose names include whitespace characters. (process_begin): If exec_name is a batch file with whitespace characters in its name, pass NULL as the first argument to CreateProcess. This avoids weird failures due to buggy quoting by CreateProcess. For the details, see the discussion starting at http://lists.gnu.org/archive/html/make-w32/2013-04/msg00008.html.
2013-05-03Fix interfacing with and remaking dynamic objects on MS-Windows.Eli Zaretskii13-22/+105
load.c (load_object, load_file): Accept an additional argument DLP and return in it a pointer that can be used to unload the dynamic object. read.c (eval): Call load_file with an additional argument, and record the pointer returned there in the 'struct file' object of dynamic objects in that object's 'struct file'. commands.c (execute_file_commands): Unload dynamic objects before remaking them, to avoid failure to remake if the OS doesn't allow overwriting objects that are in use. filedef.h (struct file): New member dlopen_ptr. gnumake.h (GMK_EXPORT): Define to dllexport/dllimport decorations for Windows and to nothing on other platforms. (gmk_eval, gmk_expand, gmk_add_function): Add GMK_EXPORT qualifier to prototypes. makeint.h (MAIN): Define before including gnumake.h, to give correct dllexport decorations to exported functions. (load_file): Adjust prototype. loadapi.c: Don't include gnumake.h, since makeint.h already includes it, and takes care of defining MAIN before doing so. build_w32.bat (LinkGCC): Produce an import library for functions exported by Make for loadable dynamic objects. w32/compat/posixfcn.c (dlclose): New function. w32/include/dlfcn.h (dlclose): Add prototype. scripts/features/load: Fix signatures of testload_gmk_setup and explicit_setup, to bring them in line with the documentation.

2013-05-01Fix treatment of whitespace after a backslash on MS-Windows.Eli Zaretskii2-0/+13
job.c (construct_command_argv_internal): Don't treat a backslash as an escape character before whitespace, if the shell is not a Posix shell. For the description of the problem, see http://lists.gnu.org/archive/html/make-w32/2013-04/msg00014.html.

2013-04-29Support dynamic object loading on MS-Windows.Eli Zaretskii5-1/+131
w32/include/dlfcn.h: New file. w32/compat/posixfcn.c: Include dlfcn.h. (dlopen, dlerror, dlsym) [MAKE_LOAD]: New functions, in support of dynamic loading. config.h.W32.template (MAKE_LOAD): Define. load.c (load_object) [HAVE_DOS_PATHS]: Support backslashes and drive letters in file names of dynamic objects.
2013-04-29Fix the .ONESHELL operation on MS-Windows.Eli Zaretskii2-3/+9
job.c (construct_command_argv_internal) [WINDOWS32]: Return right after generating new_argv for one_shell case. This fixes the Windows build for both Unixy shell and stock Windows shells.

2013-04-28Ensure error messages are printed with sync'd output.Paul Smith6-23/+145
Enhance the child_error() function so that it will write error output to the child's sync output buffer, if it exists. If it doesn't the output goes to stdout/stderr.
2013-04-28Remove support for pre-ANSI variadic function calls.Paul Smith8-136/+22
We've required support for ANSI C (ISO C 89) or better for quite a while. Get rid of the old varags.h, doprnt() stuff and simply assume ANSI C variadic function capability and basic C runtime library support (vfprintf, vsprintf, etc.)
2013-04-28Small cleanups and fixes.Paul Smith4-12/+15
2013-04-28Fix Savannah bug #37065 with $(wildcard foo/*/.) returning non-directories.Eli Zaretskii2-1/+27
dir.c (local_stat) [WINDOWS32]: Use the wrapper on MS-Windows. If the argument ends in "dir/.", make sure the parent dir exists and is indeed a directory. Fixes Savannah bug #37065.
2013-04-28Fix a few compiler warnings found by Eli.Paul Smith2-10/+5
2013-04-28Add support for per-job output sync.Paul Smith11-105/+320
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.
2013-04-27Fix support for .ONESHELL when dealing with non-POSIX shells.Paul Smith2-26/+29
2013-04-27Rework the implementation of load.c to increase portability.Paul Smith2-59/+71
It should be sufficient, now, to write a new version of the load_object() function. That function won't be called unless we really want to load, so all checking and parsing is taken care of before that.

read.c (record_files): Pay attention to .ONESHELL in MS-Windows. job.c (construct_command_argv_internal): Support .ONESHELL on MS-Windows, when the shell is not a Unixy shell.

2013-04-27Support --output-sync on MS-Windows.Eli Zaretskii12-42/+556
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.
