* src/configh.dos: Define MK_DJGPP.
* src/config.h.W32: Define MK_W32 and WINDOWS32.
* src/build_w32.bat: Let WINDOWS32 be defined by config.h. Remove
unused setting of WIN32.

Original patch from Dmitry Goncharov <dgoncharov@users.sf.net>.
When handling a fatal signal ensure the temporary files for
stdin and the jobserver fifo (if in use) are deleted.
* src/makeint.h (temp_stdin_unlink): Declare a new method.
* src/main.c (temp_stdin_unlink): Delete the stdin temporary file
if it exists. If the unlink fails and we're not handling a signal
then show an error.
(main): Call temp_stdin_unlink() instead of unlinking by hand.
* src/commands.c (fatal_error_signal): Invoke cleanup methods if
we're handling a fatal signal.
* tests/scripts/features/output-sync: Test signal handling during
output sync and jobserver with FIFO.
* tests/scripts/features/temp_stdin: Test signal handling when
makefiles are read from stdin.
The fix for SV 12078 caused a backward-compatibility issue with some
makefiles. In order to allow users to resolve this issue, revert
that change for this release cycle: it will be reinstated in the
next release cycle. Introduce a warning if we detect that the recipe
of a multi-target pattern rule doesn't create all the targets.
* NEWS: Announce the future backward-incompatibility.
* doc/make.texi (Pattern Intro): Describe the behavior and that it
will change in the future.
* src/remake.c (check_also_make): Check for also_make targets that
were not created and generate a warning.
(update_goal_chain): Call the new function.
(check_dep): Ditto.
(update_file_1): Defer implicit rule detection until after we check
all the also_make files (as it used to be).
* tests/scripts/features/patternrules: Add tests of the new warning.
Skip the tests for SV 12078.
* src/read.c (eval): Initialize the goaldep floc pointer.
* tests/scripts/features/loadapi: Verify that the floc is set after
unloading and reloading dynamic objects.
Fail if a mandatory include file fails to be built even if it's
built as part of a grouped target where the other include file
is optional.
* src/main.c (main): If a makefile doesn't build set any_failed.
* tests/scripts/features/include: Add tests.
* tests/scripts/options/dash-k: Stop after include build failure.
If any of a set of grouped targets is missing or out of date, even
if make is not trying to build that target, rebuild them all.
Ensure this is true for explicit grouped targets as well as pattern
rule grouped targets.
Original patch by Jonathan Gravel <jo@stashed.dev>
* src/remake.c (update_file_1): After matching any pattern rules,
go through the also_make targets and set noexist as needed. Also
compute the oldest this_mtime.
* tests/scripts/features/grouped_targets: Add regression tests.
* tests/scripts/features/patternrules: Ditto.
* tests/features/vpath: Rewrite to use modern run_make_test().
Add a test that we check for VPATH before implicit rule search.
Move the tests in vpath2 and vpath3 into this suite.
* tests/features/vpathplus: Rewrite to use modern run_make_test().
If makefile rules do not update an unloaded shared object, load it
again. Avoid double loading of the same object if the setup function
returns -1.
* src/filedef.h (struct file): Add "unloaded" flag.
* src/makeint.h (load_file): Take struct file *.
(unload_file): Return int.
* src/main.c (main): Reload unloaded shared objects if they weren't
updated.
* src/commands.c (execute_file_commands): Set "unloaded" and reset
"loaded" when a shared object is unloaded.
* src/read.c (eval): Set "loaded" and reset "unloaded" when a shared
object is loaded. Add successfully loaded files to the db.
* src/load.c (load_file): Check "loaded" to avoid double loading the
same object. Fix a memory leak of string loaded. Return -1, rather
than 1, if the object is already loaded. This fixes double loading of
the same object when the setup routine returns -1.
(load_object): Add a log message.
(unload_file): Return an error on dlclose failure. Log a message.
* tests/scripts/features/loadapi: Add new tests.
Allow build systems to choose an alternative location for make to
store its temporary files.
* NEWS: Announce the new environment variable.
* doc/make.texi (Temporary Files): Provide documentation.
* src/misc.c (get_tmpdir): Split into a new function. Compute the
temporary directory and store it in a static location.
* tests/scripts/features/jobserver: Add a test of MAKE_TMPDIR.
* src/load.c (load_file): Update .LOADED if setup returns non-0.
* tests/scripts/features/load: Change the return value based on an
environment variable. Ensure that returning -1 still adds to
.LOADED. Also add a test that verifies that make doesn't try to
rebuild the loaded file if -1 is returned.
* tests/scripts/features/load: Add function prototypes.
* tests/scripts/features/temp_stdin: Only set user execute bits.
Some configurations don't allow changing the group bits...??
* maintMakefile: Remove the template headers as prerequisites.
* tests/scripts/features/jobserver: Only test fifo if enabled.
* tests/scripts/variables/INCLUDE_DIRS: On MacOS none of the default
directories exist so .INCLUDE_DIRS is empty by default.
* tests/scripts/features/se_explicit: Fail via exit. cp will show
different error messages on different systems.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
Reset the temp directory for every test to a local directory, then
after each test see if any new temp files were created and not
deleted: if they were then fail the test. Rather than delete the
temp files we leave them there and avoid reporting files that were
seen before, so the user can investigate them.
Rewrite the temp_stdin tests to rely on this built-in behavior
rather than implementing the checks directly.
* tests/test_driver.pl: Create a $TEMPDIR variable pointing to a
temporary directory outside the test temp directory.
(toplevel) Before starting any tests create a temp directory and set
the POSIX and Windows temp directory environment variables to use it.
(compare_output) Check the contents of the temp directory. If any
new files have appeared, fail the test.
* tests/scripts/features/temp_stdin: Remove check_tempfile() and
all users of it, plus setting of temp environment variables.
* README.git: Clarify that these methods are lightly tested.
* build_w32.bat: Don't support any config step: fail if not completed.
Move the config steps into bootstrap.bat. Don't print compile lines
by default and add a --verbose option to show them.
* bootstrap.bat: Ensure we have curl and sed before we do anything.
Pull the latest necessary files from gnulib. Create a convert.sed
script that can update the various template files, and update
Basic.mk, config.h.W32, and gmk-default.h.
* tests/run_make_tests.pl: Remove CRLF rather than using chop. If we
run perl in Git for Bash it seems to handle newlines differently.
* tests/scripts/features/temp_stdin: Remove the make copy and close
STDIN so we can delete the temp file on Windows.
* .gitignore: Ignore the convert.sed script.
Using anonymous pipes for jobserver support has some advantages:
for example there is nothing on disk that needs to be cleaned up.
However it has many obscure problems, related to the fact that in
order for it to work we need to ensure these resources are properly
passed through to child processes that want to use the jobserver.
At the same time we don't want to pass the pipe to process which
DON'T know about the jobserver.
Other processes can open file descriptors which we then think are
our jobserver, but aren't. And, we open the pipe file descriptors
in blocking mode which doesn't work for all users.
See issues such as SV 57178, SV 57242, and SV 62397
To avoid these issues, use named pipes (on systems where they are
available) instead of anonoymous pipes. This simplifies many things:
we never need to pass open file descriptors to our children; they
can open the jobserver named pipe. We don't need to worry about
recursive vs. non-recursive children. Users don't have to "pass
through" the resources if they are invoking sub-makes. Each child
can open its own file descriptor and set blocking as needed.
The downside is the named pipe exists on disk and so must be cleaned
up when the "top-level" make instance exits.
In order to allow make to continue to be used in build systems where
older versions of GNU make, or other tools that want to use the
jobserver, but don't understand named pipes, introduce a new option
--jobserver-style that allows the user to choose anonymous pipes.
* NEWS: Announce the change and the --jobserver-style option.
* doc/make.1: Add --jobserver-style documentation.
* doc/make.texi (Special Variables): Add missing items to .FEATURES.
(Options Summary): Add --jobserver-style.
(POSIX Jobserver): Named pipes, changes to --jobserver-auth, and the
--jobserver-style option.
(Windows Jobserver): Document --jobserver-style for Windows.
* configure.ac: Check for mkfifo.
* src/config.h-vms.template: Undefined HAVE_MKFIFO.
* src/config.h.W32.template: Ditto.
* src/main.c: Add jobserver-style as a new command line option.
(main): Add jobserver-fifo to .FEATURES if supported. Pass the style
option to jobserver_setup().
* src/os.h (jobserver_setup): Accept a style string option.
* src/posixos.c (enum js_type): Enumeration of the jobserver style.
(js_type): Which style we are currently using.
(fifo_name): The path to the named pipe (if in use).
(jobserver_setup): If no style is given, or "fifo" is given, set up a
named pipe: get a temporary file and use mkfifo() on it, then open it
for reading and writing. If something fails fall back to anonymous
pipes.
(jobserver_parse_auth): Parse jobserver-auth to determine the style.
If we are using a named pipe, open it. If we're using anonymous pipes
ensure they're valid as before.
(jobserver_get_invalid_auth): Don't invalidate the jobserver when
using named pipes.
(jobserver_clear): Clean up memory used for named pipes.
(jobserver_acquire_all): Unlink the named pipe when done.
* src/w32/w32os.c (jobserver_setup): Check the style argument.
* tests/scripts/features/jobserver: Use --jobserver-style to test
the anonymous pipe behavior, and also test named pipe/semaphore
behavior. Check invalid jobserver-style options.
* tests/scripts/functions/shell: Use --jobserver-style to test the
anonymous pipe behavior, and also test named pipe/semaphore
behavior.
Second-expand only the prerequisites of the targets being built.
Defer second-expanding the prerequisites of targets until we need
to decide if they should be built.
* NEWS: Mention the change in behavior.
* doc/make.texi (Secondary Expansion): Document the new behavior.
* src/filedef.h (struct file): Add flag snapped.
(expand_deps): Declare a function to second expand the
prerequisites of a target.
* src/file.c (rehash_file): Merge flag snapped.
(expand_deps): Remove qualifier static. Check flag snapped.
(snap_deps): Remove the loop which performed second expansion for all
targets.
* src/remake.c (update_file_1): Second expand the prerequisites of
the considered target.
* tests/scripts/features/se_explicit: Add tests.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
* src/file.c (rehash_file): Fix warning message.
(rehash_file): Fix comment to match the behavior.
* tests/scripts/features/se_explicit: Fix test.
* tests/scripts/features/mult_rules: Add a new test.
During second expansion of pattern rules only the first pattern in
each "group" was being substituted. E.g. in this makefile:
.SECONDEXPANSION:
all: hello.x
%.x: $$(wordlist 1, 99, %.1 %.%.2) ; $(info $@ from $^)
hello.1 hello.\%.2 \%.1 \%.\%.2: ;
the output would build "hello.1" and "%.%.2" because each function
is considered a single "word" and only the first pattern is replaced.
Fix the expansion so each whitespace-separated string is considered a
word and the first pattern is replaced, giving "hello.1" and
"hello.%.2".
* src/rule.c (snap_implicit_rules): Keep enough space to replace %
with $(*F) if necessary.
* src/implicit.c (pattern_search): During second expansion break each
get_next_word result into individual words and replace the first % in
each with $* or $(*F) as needed.
* tests/scripts/features/patternrules: Add tests for variations.
The hash function we use can yield different results on big- and
little-endian systems which makes test output different. Choose
names to avoid this.
* tests/scripts/features/patternrules: Choose portable target names.
* tests/scripts/features/se_explicit: Ditto.
* tests/scripts/features/se_implicit: Ditto.
Previously we always used the file->stem value as our stem in
set_file_variables(); when that wasn't correct we had to temporarily
set that value while the function was called, then reset it afterward.
This led to issues (for example when we assumed the stem was a cached
string but it wasn't).
Avoid this by passing in the stem as an argument so that different
values can be provided.
Add tests to verify this.
* src/commands.c (set_file_variables): Take second parameter stem to
relieve the callers of set_file_variables() from setting/restoring
file->stem.
* src/commands.h (set_file_variables): Ditto.
(execute_file_commands): Pass file->stem to set_file_variables().
* src/file.c (expand_deps): Pass d->stem to set_file_variables() and
remove set and restore of file->stem.
* src/implicit.c (pattern_search): Pass stem to set_file_variables()
and remove set and restore of file->stem.
* tests/scripts/features/se_explicit: Add new tests.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
* tests/scripts/variables/automatic: Ditto.
During normal pattern rule expansion only the first pattern (%) is
expanded; however during secondary expansion all patterns were
expanded. Modify secondary expansion to match the behavior of normal
expansion.
Implementation tweaked by Paul Smith <psmith@gnu.org>
* src/file.c (expand_deps): Don't use subst_expand() which replaces
all % with $*: instead replace only the first one, by hand.
Fix a memory leak where the dep structure was not always freed.
* tests/scripts/features/statipattrules: Use .RECIPEPREFIX not TAB.
Add a series of tests verifying that static pattern rules with and
without secondary expansion both return the same results.
Original patch from Dmitry Goncharov <dgoncharov@users.sf.net>
Fix the ar flags to match the default values in make. If the
U option is supported, add it to the end not the beginning,
since ARFLAGS now starts with a "-".
* tests/test_driver.pl: Add defaults for global variables.
(get_osname): Preserve $osname if it's set from $^O
* tests/scripts/features/archive: Set the default arflags.
If "U" is available add it to the end of the flags.
If the re-exec fails, be sure to remove a temp makefile that was
created to read from stdin.
* src/job.c (exec_command): Return on failure.
(child_execute_job): Call exit if exec_command returns.
* src/job.h (exec_command): Don't mark as NORETURN.
* src/main.c (main): Unlink stdin temporary file if re-exec fails.
* tests/run_make_tests.pl: Get value for ERR_nonexe_file/ERR_exe_dir.
* tests/scripts/features/temp_stdin: Test that temp file unlink works.
The fix for SV 60595 causes make to re-execute when the makefile is
read from stdin. E.g.
$ printf 'all:; $(info hello)' | make -sf -
Reported by Sergei Trofimovich <siarheit@google.com>
Test added by Paul Smith <psmith@gnu.org>
* src/main.c (main): Set the mtime of the stdin temporary file.
* tests/scripts/features/reinvoke: Add a test.
We already use undef makefile strings to mean "re-use the previous
makefile", so if the string is empty we'll assume it means "don't
use a makefile at all" (don't add -f).
* tests/run_make_tests.pl (run_make_test): If the makefile string
is empty, don't create a makefile or add -f.
* tests/scripts/features/include: Change empty makefile to "\n".
* tests/scripts/misc/close_stdout: Ditto.
* tests/scripts/options/dash-r: Ditto.
If a prereq of a pattern is explicitly mentioned as a prereq of an
unrelated rule, it should not be considered an intermediate file.
* tests/scripts/features/double_colon: Add tests mentioning unrelated
explicit targets.
* tests/scripts/features/grouped_targets: Ditto.
* tests/scripts/features/implicit_search: Ditto.
* tests/scripts/features/patternrules: Ditto.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/statipattrules: Ditto.
The fix for SV 60595 introduced a backward-incompatibility: rules that
purported to rebuild included files, but didn't actually do so, were
treated as errors whereas before they were ignored. This breaks a
common idiom in makefiles where an empty recipe is created for an
included makefile so make doesn't complain if it doesn't exist.
Unfortunately this means make cannot diagnose some types of errors.
Extra tests supplied by Dmitry Goncharov <dgoncharov@users.sf.net>.
* doc/make.texi (Including Other Makefiles): Clarify this behavior.
* src/main.c (main): Don't run the new check-for-errors behavior.
* tests/scripts/features/reinvoke: Reset tests of the "old" behavior
and add new tests for this situation.
In SV 43677 we forced targets to be secondary if we found an
intermediate file that was listed as a prerequisite of another
target. This overrides .INTERMEDIATE settings, so doesn't work.
Now that we have an is_explicit flag in targets, use that instead.
* src/implicit.c (pattern_search): Remove setting of secondary.
Preserve the value of the is_explicit flag when creating a new
file target, and consider it when setting the intermediate flag.
* tests/scripts/features/patternrules: Add a test w/out INTERMEDIATE
* tests/scripts/targets/INTERMEDIATE: Add a test with INTERMEDIATE
Target-specific variables used to define the target as "ought to
exist" so they could never be intermediate. Now they can be, so
merge the target-specific variables from the intermediate target
so they're not lost.
* src/implicit.c (pattern_search): Use merge_variable_set_lists
to merge target-specific variables.
* tests/scripts/features/implicit_search: Add tests of target-
specific variable assignments and implicit rules.
* tests/scripts/features/errors: Match Windows-specific errors.
* tests/scripts/features/targetvars: Match Windows-specific errors.
* tests/scripts/misc/general4: Match Windows-specific errors.
The traditional definition of "ought to exist" in the user's manual can
lead to make choosing a poor series of chained implicit rules. Modify
that rule so that we first attempt to resolve implicit rules by
considering targets which are only (a) targets or (b) explicit
prerequisites of the current target.
For backward-compatibility, if we don't find a solution using that
algorithm use the previous definition where "ought to exist" means
"mentioned as a prerequisite of any target".
* src/implicit.c (pattern_search): An extra argument controls whether
to perform the backward-compatible rule search or not. If a prereq is
a target, or if it's a prerequisite of THIS target, then choose it.
If we get to the end and haven't found a match, but we have found a
potential compatibility rule, then retry with compat rules enabled.
If we're searching with compat rules enabled and we find a file
mentioned as a prerequisite of ANY target, then use it.
* tests/features/implicit_search: Provide a large suite of tests for
different steps of implicit rule search.
If multiple intermediate files are built together be sure all of them
are removed after make is finished. Continue to ensure that targets
that exist before make starts are not removed even if they appear to be
intermediate.
Add a number of tests to pattern rules to verify this behavior.
* src/filedef.h (struct file): Add a new is_explicit bitfield.
* src/file.c (rehash_file): Merge the is_explicit bit.
(enter_prereqs): Set is_explicit if the file is explicitly mentioned.
* src/implicit.c (pattern_search): Set intermediate on the file if it's
not explicit.
(record_files): Set is_explicit if a file is mentioned as a target.
* src/remake.c (update_file_1): Set secondary on files that already
exist so they won't be removed.
* tests/scripts/features/double_colon: Add a test for double-colon
pattern rules.
* tests/scripts/features/patternrules: Update KGO for tests where more
files are removed.
Add new tests to verify handling removal of intermediate files in the
context of grouped pattern targets.
If we find an included makefile but it's not readable, stop
immediately with an error rather than continuing to look in other
directories.
* src/read.c (eval_makefile): Only keep searching if the fopen error
is ENOENT, else stop and fail.
* tests/scripts/features/include: Add tests to verify this behavior.
Change the handling of included makefiles which are phony targets to
be similar to double-colon rules with no prerequisites: simply don't
build them at all during the remake a makefile phase.
Ensure that any included makefile which is needed but not built
results in an error.
Update the documentation to make this clear.
Add tests to verify this behavior.
* doc/make.texi (Remaking Makefiles): Clarify double-colon exception.
Document that phony targets are handled the same way.
(Phony Targets): Ditto.
* src/main.c (main): Check for phony targets when skipping goals.
Rather than throwing out skipped but failed goals keep them
separately then report them as errors.
* src/read.c (eval): Set the file location on included makefiles even
when there's no error.
* tests/scripts/features/include: Add tests for handling included
makefiles with both phony and double-colon rules to rebuild them.
Previously if an included makefile was rebuilt as a prerequisite of
another included makefile which didn't need to be rebuilt, make would
not realize that it needed to re-exec itself.
Ensure that if any included makefile target is rebuilt we re-exec.
Also ensure that if an included makefile is not readable, and our rule
for rebuilding it doesn't actually change it, we will still fail.
* src/remake.c (update_goal_chain): If a goal's update was successful
then check its status, even if no actual commands were run because it
was already up to date.
(show_goal_error): Remove superfluous cast.
* src/main.c (main): If the makefile remake did nothing, check that we
were able to successfully include all the makefiles we care about; if
not fail. When generating error messages about included makefiles be
sure to show the filename/linenumber information.
* test/scripts/features/reinvoke: Add tests for this behavior.
* test/scripts/options/dash-k: Update error messages.
Set the $$< automatic variable as best we can during secondary
expansion of prerequisites.
* src/commands.c (set_file_variables): Don't break without setting
'less' if secondary expansion is enabled.
* tests/scripts/features/se_explicit: Test secondary expansion results.
* tests/scripts/features/se_implicit: Test secondary expansion results.
* src/dep.h (DEP): Remove extraneous semicolon.
* src/dir.c (find_directory) [W32]: Replace removed variable.
* tests/scripts/features/include: Allow the extra default makefile
searched for on Windows.
* tests/scripts/functions/file: Use $(info ...) to avoid "command
too long" errors on Windows.
If a prereq of a pattern is an explicit target, it should not be
considered an intermediate file.
(Minor tweaks by Paul Smith <psmith@gnu.org>)
* src/dep.h (struct nameseq): Add is_explicit flag.
* src/implicit.c (struct patdeps): Ditto.
(pattern_search): Set the is_explicit flag appropriately for each
prerequisite, based on whether it contained a pattern or not.
Update the help output to note implicit vs. explicit prereqs.
* tests/scripts/features/double_colon: Add tests.
* tests/scripts/features/grouped_targets: Ditto.
* tests/scripts/features/patternrules: Ditto.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/statipattrules: Ditto.
If a -include file does not exist, then some subsequent operation
creates it, then allow it to be successfully included.
* src/read.c (eval_makefile): If our last mtime was NONEXISTENT then
reset it to 0 so we'll check it again.
* tests/scripts/features/include: Add a test for this behavior.
