2013-09-21Don't write "Entering" every time we re-exec for remake makefiles.Paul Smith2-0/+37
2013-09-15[SV 27374] Fatal immediately on unrecoverable fopen() errors.Paul Smith4-27/+54
2013-09-15[SV 39934] Verify jobserver FDs before something else uses them.Paul Smith2-0/+23
2013-09-15[SV 39203] Don't set MAKEFLAGS when restarting.Paul Smith2-0/+15
We are restarting with the original command line flags, so if we set MAKEFLAGS as well that will cause double flags.
2013-09-14Support the -Orecurse option properly.Paul Smith2-2/+4
In this mode we still collect all the output from a given target and dump it at once. However we don't treat recursive lines any differently from non-recursive lines. Also we don't print enter/leave messages after every dump. However we do ensure that we always print them once to stdout, so the parent make will collect it properly.
2013-09-12Enhance the output sync mode.Paul Smith5-4/+38
Create a new file, output.c, and collect functions that generate output there. We introduce a new global context specifying where output should go (to stdout or to a sync file), and the lowest level output generator chooses where to write output based on that context. This allows us to set the context globally, and all operations that write output (including functions like $(info ...) etc.) will use it. Removed the "--trace=dir" capability. It was too confusing. If you have directory tracking enabled then output sync will print the enter/leave message for each synchronized block. If you don't want that, disable directory tracking.
2013-07-22[Bug #39310] Parse simple pattern prereqs for globbing.Paul Smith2-0/+42
We tried to get some efficiency by avoiding a parse_file_seq() for simple pattern prerequisites, but this also means no wildcard expansion was happening, so add it back. Add regression tests for wildcards in target and prerequisite lists.
2013-07-09Keep a local count of the max dependency list size.Paul Smith2-0/+27
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 Smith2-0/+22
2013-05-26[SV #38945] Copy the entire buffer back when overwriting CRPaul Smith2-2/+8
2013-05-26[SV #39035] Compare OUT to the beginning of the OUT var/func, not IN.Paul Smith2-0/+26
2013-05-22Fix regression tests after MAKEFLAGS enhancements.Paul Smith4-8/+14
2013-05-17Update source file format: remove TABs, use GNU coding styles.Paul Smith2-8/+8
2013-05-17Update copyright for changes in 2013.Paul Smith6-6/+6
2013-05-14Add requirement for plugin_is_GPL_compatible symbol in loaded objects.Paul Smith3-0/+9
2013-05-13Add a new variable: GNUMAKEFLAGSPaul Smith1-0/+24
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 Smith1-14/+10
Fixes Savannah bug #2216.
2013-05-13Add new --trace[=MODE] flags, with --trace=dirPaul Smith2-8/+5
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 Smith2-4/+5
2013-05-05Ensure command lines are written synchronously with -O.Paul Smith2-17/+17
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 Smith2-1/+7
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 Smith2-0/+15
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 Zaretskii2-2/+7
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 Smith2-6/+3
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 Smith2-15/+101
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.

2013-02-25Expand the loadable object support.Paul Smith5-48/+157
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.
