This also includes fixing the most of the exit handling code for VMS.
Self tests:
Previously about 94 Tests in 36 categories fail.
Now about 45 tests in 22 categories fail.
Because some tests do not properly clean up, the number of tests that
fail can vary by one or two test cases between consecutive runs.
* Makefile.am: Add new VMS files.
* job.c: add prototype for vms_strsignal().
* job.c: (child_error): Remove VMS specific code as no longer needed.
* job.c: (reap_children): The VMS specific code was setting the
status to 0 instead of setting it to the proper exit status.
* job.h: Add vms_launch_status to struct child.
* main.c: (main): Use environment variables for options to use MCR
* instead of a foreign command, and to always use command files for
subprocesses.
For VMS use (set_program_name) routine which is common to ports of
other GNU packages to VMS to set the program name used internally.
Use (vms_putenv_symbol) to set up symbols to be visible in child
programs, including recursive make launched by execve()
Start of Bash shell detection code for VMS.
* makefile.com: Need nested_include=none for building on VMS search
lists. Add vms_progname, vms_exit, and vms_export_symbol.
* makefile.vms: Need nested_include=none for building on VMS search
lists. Add vms_progname, vms_exit, vms_export_symbol.
* makeint.h: Make sure non-standard "VMS" macro is defined. Add
prototypes for new VMS routines. Remove VMS-specific failure codes.
* vmsjobs.c: Add VMS POSIX exit code constants.
(_is_unixy_shell): Detect Bash shell.
(vms_strsignal): simulate strsignal() on VMS.
(vmsHandleChildTerm): fix to properly report failed LIB$SPAWN() exit
status codes. Remove code that duplicated code in job.c.
(child_execute_job): Export environment symbols before spawning a
child and restore afterward unless option to use command files for
subprocesses is set. Improve handling of UNIX null commands ":".
* vms_exit.c: Provides vms_exit() to detect if an exit code is UNIX
or VMS, and converts the UNIX code into a VMS exit code.
* vms_export_symbol.c: Routines to create DCL symbols that work like
shell aliases or exported shell symbols and clean them up on exit.
* vms_export_symbol_test.com: Unit test for vms_export_symbol.c
* vms_progname.c: New file: VMS specific replace for progname.c that
is used in some GNU projects.

* output.c (error, fatal, message): Take an extra argument specifying
how many bytes are used by the formatted arguments.
(get_buffer): New function that allocates the requested buffer size.
Remove msc_vsnprintf(), vfmtconcat(), and fmtconcat() as unneeded.
* makeint.h: Declare various helper macros for generating output.
* *.c: Change all error(), fatal(), message() calls to use the macros,
or pass the extra length argument directly.

w32/compat/posixfcn.c: Fix the forgotten OUTPUT_SYNC conditional.
job.h: Ditto, but in a comment.

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.

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.

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.

The new GNU Maintainer's Manual allows the use of year ranges in certain
situations; take advantage of this simplification.

Taylor. There are two forms of this: first, it was possible to lose
tokens when using -j and -l at the same time, because waiting jobs were
not checked when determining whether any jobs were outstanding. Second,
if you had an exported recursive variable that contained a $(shell ...)
function there is a possibility to lose tokens, since a token was taken
but the child list was not updated until after the shell function was
complete.
To resolve this I introduced a new variable that counted the number of
tokens we have obtained, rather than checking whether there were any
children on the list. I also added some sanity checks to make sure we
weren't writing back too many or not enough tokens. And, the master
make will drain the token pipe before exiting and compare the count of
tokens at the end to what was written there at the beginning.
Also:
* Ensure a bug in the environment (missing "=") doesn't cause make to core.
* Rename the .DEFAULT_TARGET variable to .DEFAULT_GOAL, to match the
terminology in the documentation and other variables like MAKECMDGOALS.
* Add documentation of the .DEFAULT_GOAL special variable.
Still need to document the secondary expansion stuff...

|
* Update maintainers build process; remove GNUmakefile. Require builders to
run automake && autoreconf by hand.
* Use AC_SUBST_FILE to get the maintMakefile included, rather than GNU
make's include directive, which conflicts with automake 1.4's include
directive.
