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.
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.
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.
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.)
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.
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.
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.
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.
build_w32.bat: Improve. Remove 'setlocal', as it isn't
supported on Windows 9X. Add --help and usage instructions.
Support both debug and optimized builds with GCC under --debug.
If building out of Git repo, always produce config.h, and edit
gmk-default.scm into gmk-default.h.
w32/subproc/build.bat: Support debug and optimized builds with
GCC.
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.
