2013-07-09Keep a local count of the max dependency list size.Paul Smith1-0/+22
This global variable could be modified during recursion so keep our own local copy to compare against.
2013-05-26[SV #38442] Add library names to the string cache.Paul Smith1-0/+20
2013-05-14Add requirement for plugin_is_GPL_compatible symbol in loaded objects.Paul Smith2-0/+4
2013-05-13Add new --trace[=MODE] flags, with --trace=dirPaul Smith1-8/+0
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 Smith1-4/+4
2013-05-05Ensure command lines are written synchronously with -O.Paul Smith1-17/+11
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 Smith1-1/+5
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 Smith1-0/+10
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.
2013-05-03Fix interfacing with and remaking dynamic objects on MS-Windows.Eli Zaretskii1-2/+2
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.
2013-04-28Ensure error messages are printed with sync'd output.Paul Smith1-6/+2
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.
2013-04-28Small cleanups and fixes.Paul Smith1-5/+5
2013-04-28Add support for per-job output sync.Paul Smith1-15/+96
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.
2013-04-15Change the arg option for -O from numeric to string.Paul Smith1-2/+2
2013-04-15Modify output-sync tests to be more reliable.Paul Smith1-25/+63
2013-04-14Rename the "parallel-sync" option to "output-sync".Paul Smith1-26/+16
2013-04-14Initial patch for output synchronization. See Savannah bug #33138.Frank Heckenbach1-0/+143
Based on work by David Boyce <David.S.Boyce@gmail.com>.
2013-02-25Expand the loadable object support.Paul Smith2-38/+115
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.
2013-01-20Allow dynamically loaded objects to be rebuilt by make.Paul Smith1-7/+30
2013-01-13[SV #37878] Add a check for targets with parens that are not archives.Paul Smith1-0/+8

Fixes Savannah bug #34530.
2011-11-14Be sure to start parsing prereqs in the right place even if there arePaul Smith1-0/+9

2011-09-18When we re-exec the master makefile in a jobserver environment, ensurePaul Smith1-0/+17
that MAKEFLAGS is set properly so the re-exec'd make runs in parallel. See Savannah bug #33873.
2011-09-18We compute various values for vpath lookup the first time throughPaul Smith1-40/+25
and store them in static variables; however one value (std_dirs) was not being stored statically so the second time through it was not set. Fixes Savannah bug #32511
2011-08-29Save strings we're expanding in case an embedded eval causes themPaul Smith1-23/+24
to be freed (if they're the value of a variable that's reset for example). See Savannah patch #7534
2011-06-12Fix another error related to whitespace handling in archives.Paul Smith1-0/+5
Newer version of VMS support strncasecmp() so update the config.h.
2011-04-18Add new feature: != shell assignment for portability with BSD make.Paul Smith1-0/+65
Feature submitted by David Wheeler.
2010-11-30Check if the target-specific variable is the same as the globalPaul Smith1-0/+10

2010-07-01- Add whitespace to command line invocation in features/recursionPaul Smith1-1/+1

2009-11-12Implement linker-compatible library search.Boris Kolpackov1-0/+50
2009-10-06Fix savannah bug 25780. Optimize things a bit.Boris Kolpackov1-9/+4

2009-09-24- Rework secondary expansion so we only defer it if there's a possibilityPaul Smith5-172/+129
