* bootstrap.conf: Switch to gnulib stable-202401 branch.
* maintMakefile: Support an EXTRA_CFLAGS variable in maintainer mode.
* README.git: Describe how to use it.
* bootstrap.conf: Request the latest gnulib stable branch.
* README.git: Recommend the argument form of autogen/autopull.
* bootstrap: Import the latest version of bootstrap.
* bootstrap-funclib.sh: Ditto.
* autogen.sh: Ditto.
* autopull.sh: Ditto.
* bootstrap.conf: Get gnulib's sig_atomic_t type checking M4 macro.
* configure.ac: Invoke it.
* src/makeint.h (handling_fatal_signal): Set the type correctly.
* src/commands.c (handling_fatal_signal): Ditto.
Don't assume that time_t fits in long, as some hosts (e.g.,
glibc x86 -D_TIME_BITS=64) have 32-bit long and 64-bit time_t.
* bootstrap.conf (gnulib_modules): Add largefile, to support files
with timestamps after Y2038 on hosts with 32-bit long.
* configure.ac: Do not call AC_SYS_LARGEFILE, as the largefile module
does that for us.
* src/makeint.h (PRIdMAX, PRIuMAX, SCNdMAX): Define if not already
defined (taken from gnulib).
* src/ar.c: Include intprops.h, for TYPE_MAXIMUM, as
INTEGER_TYPE_MAXIMUM does not work on time_t without issuing a bunch
of warnings.
(ar_member_date): Check that result is in time_t range.
(ar_member_date_1): Use intmax_t to hold the date.
(ar_glob_match): Ditto.
* src/arscan.c (VMS_function, VMS_function_ret, ar_scan)
(parse_int, ar_scan, ar_member_pos, ar_member_touch)
(describe_member): Convert long int to intmax_t.
* src/file.c (file_timestamp_sprintf): Use intmax_t/uintmax_t instead
of long/unsigned long for values that might be time_t.
* src/arscan.c (ar_member_touch): Fix buffer overrun if the timestamp
is too large.
* README.git: Document the changes.
* bootstrap.conf: Set GNULIB_REVISION to avoid random updates.
* configure.ac: Set the minimum autoconf version back to 2.69:
that's the most common version deployed today, and it still works.
* bootstrap: Copy the latest from gnulib.
* autogen.sh: Ditto.
* autopull.sh: Ditto.
* bootstrap-funclib.sh: Ditto.
The gl subdirectory contains our local versions of gnulib module
implementations, so move m4/acinclude.m4 and m4/dospaths.m4 there.
* gl/modules/make-macros: Create a new module to handle the macros.
* bootstrap.conf: Add the new module.
* configure.ac: Macro invocation is moved to make-macros.
* m4/.gitignore: Delete unnecessary ignore file: m4 is empty.
* .gitignore: Add m4/ as an ignored directory.
This pulls in entirely too much stuff we don't need. Instead grab
just the gnulib source file, then include it in src/misc.c.
* bootstrap.conf: Add just the lib/strtol.c source file.
* configure.ac: Check for strtoll.
* src/misc.c: Include strtol.c, with QUAD set, if needed.
This pulls in a metric ton of stuff that we otherwise don't need, just
for a one-liner that we already have a replacement for in src/misc.c.
* bootstrap.conf: Remove mempcpy
* configure.ac: Add mempcpy to AC_CHECK_FUNCS
We can assume that the return type of a signal handler is void.
We can assume that, if sys/time.h exists, it can be included
with time.h.
* bootstrap: Get the latest version
* configure.ac: Require a newer version of autoconf.
Remove unnecessary AC_PROG_CC_C99 (already have AC_PROC_CC).
Remove unnecessary AC_AIX, AC_ISC_POSIX, AC_MINIX.
Remove unnecessary AC_HEADER_STDC, AC_HEADER_TIME, AC_TYPE_SIGNAL.
Use strerror to search for the cposix library.
* src/commands.c (fatal_error_signal): Assume return type is void.
* src/commands.h: Ditto.
* src/job.c: Ditto.
* src/job.h: Ditto.
* src/main.c: Ditto.
* src/makeint.h: Ditto.
Don't bother with TIME_WITH_SYS_TIME.
* src/remote-cstms.c: Check HAVE_SYS_TIME_H.
* src/config.ami.template: Remove RETSIGTYPE.
* src/config.h-vms.template: Ditto.
* src/config.h.W32.template: Ditto.
Remove TIME_WITH_SYS_TIME.
Modify make functions that parse integer values to use long long
values instead of long: on Windows long is the same as int (4 bytes)
and we don't want behavior to differ between different platforms.
* bootstrap.conf: Change strtol module to strtoll module.
* src/function.c (parse_numeric): Use strtoll() and return long long.
(func_word): Use long long.
(func_wordlist): Use long long. Verify second argument is >= 0.
(func_intcmp): Use long long.
* src/config.ami.template: Don't define HAVE_STRTOLL.
* src/config-vms.template: Define HAVE_STRTOLL.
* src/config.W32.template: Define HAVE_STRTOLL.
* tests/run_make_tests.pl: Set $ERR_out_of_range to the proper string.
* tests/scripts/functions/word: Rework to use the new style and avoid
TAB characters. Verify trailing whitespace is ignored. Add a test
for a negative second argument to wordlist. Add tests for max signed
integer values. Use $ERR_out_of_range for the error string.
* tests/scripts/functions/intcmp: Add tests for min and max signed
integer values. Use $ERR_out_of_range for the error string.
strtol() is part of C89 and a fallback is provided by gnulib.
* src/function.c (func_word, func_wordlist): Change atoi to strtol.
* test/scripts/functions/word: Add out-of-range verification testing.
Logging of implicit rule search gives limited information as to why a
given implicit rule was rejected, and if no implicit rule is found we
get the confusing "No rule to make target" result when the real issue
is that some prerequisite of some implicit rule could not be built.
Enhance logging around implicit rule search as follows:
1. The messages which refer to a rule print a description (the targets
and prerequisites) of the rule.
2. A new message tells when a rule is rejected, along with the reason.
3. The 'Looking for an implicit rule...' message is printed for every
prerequisite, not just the top-level target.
4. "Trying harder" message is printed, when intermediate prerequisites
are going to be searched.
5. The 'No rule found...' and 'Found implicit rule...' messages are
printed for every prerequisite, not just the top-level target.
6. "Ought to exist...", "Found..." or "Not found..." message is
printed for each prerequisite.
* src/rule.h (struct rule): Remember the definition of the rule.
* src/rule.c (get_rule_defn): Compute the definition of a rule.
(install_pattern_rule): Initialize the definition to empty.
(create_pattern_rule): Ditto.
(freerule): Free the definition.
(print_rule): Use the definition when printing rules.
* src/remake.c (update_file_1): Push debug output down into
try_implicit_rule().
* src/implicit.c (try_implicit_rule): Add debugging
(pattern_search): Show the rule definition in various debug output.
Add new debug messages for implicit rule search.
Additional changes by Paul Smith <psmith@gnu.org>:
Since we usually don't need the rule definition, defer computing it
until we do.
* bootstrap.conf: Include the mempcpy Gnulib module.
* src/makeint.h (mempcpy): Declare mempcpy if not available.
* src/misc.c (mempcpy): Define mempcpy if not available.
* src/config.h-vms.template: Don't set HAVE_MEMPCPY.
* src/config.h.W32.template: Ditto.
* src/rule.h (get_rule_defn): Return the definition of a rule.
* src/rule.c (get_rule_defn): If we don't have a definition compute
it; either way return it.
* src/implicit.c (pattern_search): Rework the handling of explicit
prerequisites to pattern rules to be more clear. There is no change
in behavior.
When using exec we install the child's environment before invoking
execlp(), so commands are found on the child's PATH. posix_spawnp
searches on the parent's PATH, which we don't want.
Import gnulib's findprog-in module and use it to search the child's
PATH, then use posix_spawn() to run it.
Also, posix_spawn() does not fall back to trying sh on ENOEXEC, as
execlp() does, so implement that as well.
* bootstrap.conf: Add the findprog-in gnulib module
* src/job.c: Include findprog.h if we're using posix_spawn.
(start_job_command): Remove the handling of child->cmd_name,
(child_execute_job): and add it here. Look up the command to be
run in the child's path and invoke it if found. If it fails with
ENOEXEC then retry it as an argument to the default shell.
* tests/scripts/misc/general4: Test makefile PATH assignments.
* tests/scripts/features/targetvars: Ditto, for target variables.
Move content from glob/* and config/* into standard GNU directory
locations lib/* and m4/*.
Install the gnulib bootstrap script and its configuration file, and
create a bootstrap.bat file for Windows. Update the README.git file
with new requirements and instructions for building from Git.
At this point we only install the alloca, getloadavg, and FDL modules
from gnulib. We keep our old glob/fnmatch implementation since the
gnulib versions require significant amounts of infrastructure which
doesn't exist on Windows yet. Further work is required here.
Due to a problem with gnulib's version of getloadavg, we need to bump
the minimum required version of automake to 1.16.1 unfortunately.
