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.

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.
We don't need to parse strings into C integer values to compare them.
* src/function.c (parse_textint): Find boundaries of a numeric string.
(func_intcmp): Use parse_textint() to compare integers textually.
* tests/scripts/functions/intcmp: Test with extra-large numbers.
* src/function.c (parse_numeric): Check for empty value and error.
If we find ERANGE just print our own error, not strerror.
(func_word): Use a generic "not good" error message.
(func_wordlist): Ditto
(func_intcmp): Ditto
* tests/run_make_tests.pl: Remove code to find strerror(ERANGE)
* tests/scrips/functions/intcmp: Update the error message.
* tests/scrips/functions/word: Ditto.
* tests/scripts/features/errors: Match Windows-specific errors.
* tests/scripts/features/targetvars: Match Windows-specific errors.
* tests/scripts/misc/general4: Match Windows-specific errors.
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.
Numbers can come from $(words ...), automatic variables such as
$(MAKELEVEL), from environment variables, or from shell output such as
through $(shell expr ...). The $(intcmp ...) function allows
conditional evaluation controlled by numerical variables.
* NEWS: Announce this feature.
* doc/make.texi (Functions for Conditionals): Document 'intcmp'.
* src/function.c (func_intcmp): Create the 'intcmp' built-in function.
* tests/scripts/functions/intcmp: Test the 'intcmp' built-in function.
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.
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.
* tests/scripts/options/dash-I: Use string comparison operator.
* tests/test_driver.pl (cmd2str): New method to convert a
command line to a string with proper quoting.
* tests/run_make_tests.pl (create_command): Call cmd2str() to format
the command. Add the filename/line number to the output.
POSIX Issue 8 will require a new assignment operator, :::=.
This operator behaves similarly to the BSD make := operator: the
right-hand side is expanded immediately, but then the value is
re-escaped (all '$' are converted to '$$') and the resulting variable
is considered a recursive variable: the value is re-expanded on use.
* src/variable.h (enum variable_flavor): Add f_expand flavor.
* src/variable.c (do_variable_definition): When defining f_expand,
post-process the result to re-escape '$' characters.
Remove default: to the compiler warns about un-handled enum values.
Set recursive values for both f_recursive and f_expand.
(parse_variable_definition): Rewrite this method.
The previous version was annoying to extend to ':::='.
(print_variable): Remove default: so the compiler warns us about
un-handled enum values.
* src/function.c (func_origin): Remove default: so the compiler warns
us about un-handled enum values.
* doc/make.texi: Add documentation for :::=.
* tests/scripts/variables/define: Add a test for define :::=.
* tests/scripts/variables/flavors: Add tests for :::=.
* tests/scripts/variables/negative: Add tests for :::=.
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.
When MAKEFLAGS is set in a makefile, reparse it immediately rather
than waiting until after all makefiles have been read and parsed.
This change doesn't actually fix the SV bug referenced because, even
though we do reparse MAKEFLAGS, we don't handle the -r or -R options
immediately. Doing this will require more effort.
* NEWS: Announce the change.
* src/makeint.h: Publish reset_switches() and decode_env_switches()
from main.c
* src/main.c (main): Don't call construct_include_path(); it will be
invoked decode_switches().
Preserve the old values of builtin_rules, builtin_variables, and
job_slots before we read makefiles since they can be changed now.
(reset_switches): Publish (remove static). Set the initial value of
the stringlist list to NULL.
(decode_switches): Call construct_include_path() after decoding.
(decode_env_switches): Publish (remove static).
(define_makeflags): Set the MAKEFLAGS variable for special handling.
* src/read.c (eval_makefile): Check for empty include_directories.
(construct_include_path): Clear any old value of .INCLUDE_DIRS before
appending new values. Free the previous include_directories.
* src/variable.c (lookup_special_var): When MAKEFLAGS is set, first
reset the switches then re-parse the variable.
* tests/run_make_tests.pl: Memo-ize some default variable values.
* tests/scripts/options/dash-r: Create tests for setting -r and -R.
* tests/scripts/variables/MAKEFLAGS: Test that resetting -I from
within the makefile takes effect immediately.
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.
Accept a "-" directory value to the -I option to clear the set of
directories to be searched up to that point, including the default
directories.
* NEWS: Announce the change.
* doc/make.texi (Summary of Options): Add documentation.
* src/read.c (construct_include_path): Check for '-' and if found,
clear the list of directories to be searched.
* tests/scripts/options/dash-I: Add tests for -I-.
* tests/scripts/variables/INCLUDE_DIRS: Add tests for -I-.
Support a new special target, .NOTINTERMEDIATE. Any file or pattern
prerequisite of this target will never be considered intermediate.
This differs from .SECONDARY in that .SECONDARY files won't be deleted
but they will still not be built if they are missing.
.NOTINTERMEDIATE files are treated the same way as a target which is
explicitly mentioned in the makefile. This is mostly useful with
patterns; obviously mentioning a target explicitly here is enough in
and of itself to make something not intermediate.
Some adjustments made by psmith@gnu.org
* NEWS: Announce the new feature.
* doc/make.texi (Special Targets): Document .NOTINTERMEDIATE.
(Chained Rules): Describe how to use .NOTINTERMEDIATE.

(remove_intermediates): Check notintermediate flag before removing.
(print_file):
* src/implicit.c (pattern_search): Set notintermediate based on the
pattern.

* 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.
Keep a count of bytes read rather than comparing pointers since the
variable_buffer might get reallocated.
Bug and patch by Ken Tossell <ken@tossell.net>
Regression tests by Dmitry Goncharov <dgoncharov@users.sf.net>
Tweaked by Paul Smith <psmith@gnu.org>

Add a new function $(let ...) which allows lexically scoped variables.
* NEWS: Add information on this feature.
* doc/make.texi (Let Function): Document the 'let' function.
* src/function.c (func_let): Create the 'let' built-in function.
* tests/scripts/functions/let: Test the 'let' built-in function.
Add debug options to print recipes even if they would otherwise be
silent, and to print the reason that a target was considered out of
date.
Modify --trace to simply be a shorthand for --debug=print,why.
* NEWS: Announce changes.
* doc/make.texi (Summary of Options): Document the new options.
* doc/make.1: Ditto.

(new_job): Ditto.
* src/main.c (trace_flag): Make a static variable for switches.
(decode_debug_flags): Set DB_PRINT and DB_WHY if trace_flag is set.
* tests/scripts/variables/GNUMAKEFLAGS: Update known-good messages.
* tests/scripts/variables/MAKEFLAGS: 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.
Each time we invoke a command it's possible that it will change the
filesystem in ways that were not described by the target. If that
happens but we have cached previous directory contents then we may
make decisions or report results based on obsolete information.
Keep a count of how many commands we've invoked, and remember the
current command count every time we load the contents of a directory.
If we request the directory and the current command count has changed
we know the cache is outdated so reload from scratch.
* NEWS: Announce the change.
* src/makeint.h (command_count): Create a global counter.
* src/main.c (command_count): Ditto.
* src/job.c (reap_children): Increment the counter on job completion.
* src/function.c (func_file): Increment if we write a file.
* src/dir.c (clear_directory_contents): Clear the current contents of
a cached directory.
(struct directory_contents): Remember the counter value.
(struct directory): Remember the counter value for non-existing dirs.
(find_directory): If we have a cached directory and the count hasn't
changed then return it. Else, clear the previous contents and re-read
from scratch.
* tests/scripts/features/dircache: Add tests of the directory cache.
Rewrite the environment variable algorithm to correctly inherit
export settings from parent variable sets. The new algorithm
for computing the table of environment variables is:
- Start with the most local variable set and proceed to global.
- If the variable already exists in the table and we don't know
its export status, update it with the current variable's status.
- If the variable is not in the table and it's not global, add it
regardless of its status so if it's unexported we remember that.
- If the variable is not in the table and is global, check its
export status and don't add it if we won't export it.
Then when generating the environment variables, check the export
status of each variable in case it was a target-specific variable
and we have determined it should not be exported.
Rework SHELL handling to check at the end whether we added it or
not and if we didn't, add the value from the environment.
* NEWS: Announce support for target-specific "unexport"."
* doc/make.texi (Target-specific): Document the support.
* src/variable.h (enum variable_export): Make into a global type.
* src/read.c (struct vmodifiers): Use enum variable_export rather
than individual booleans.
(parse_var_assignment): Parse the "unexport" keyword.
(eval): Remember the vmodifier value in the variable.
(record_target_var): Ditto.
* src/variable.c (should_export): Check if the variable should be
exported.
(target_environment): Implement the above algorithm.
* tests/scripts/features/export: Test export/unexport with variable
assignments on the same line.
* tests/scripts/features/targetvars: Add a comprehensive suite of
tests for different types of target-specific export / unexport.
* tests/scripts/variables/SHELL: Update the comment.
When checking for invalid environment variable names we searched the
entire name string instead of just the first LENGTH chars; this could
cause us to incorrectly decide the variable was not exportable.
Dmitry Goncharov <dgoncharov@users.sf.net> found this bug and
provided a test case and sample fix: I used the test but chose a
slightly different fix.
* src/variable.c (define_variable_in_set): check the variable name
not the input string.
* tests/scripts/features/targetvars: Ensure environment variable
values are exported.
GNU make must recognize some special targets as they are defined.
Because of the way targets are defined, we were not recognizing these
special targets until we were handling the NEXT statement. However
that's too late for some special targets such as .POSIX etc. which can
change the behavior of make during parsing.
Check for special targets earlier, as soon as we've finished parsing
the target introduction line (before we've even parsed the recipe).
* NEWS: Mention the change.
* src/read.c (check_specials): New function to look for special
targets. Move checks from eval() and record_files() to this new
function.
(eval): Call check_specials() after we've completed parsing the target
introduction line. Move default goal detection to check_specials().
(record_files): Move handling of .POSIX, .SECONDEXPANSION, and
.ONESHELL to check_specials().
* tests/scripts/misc/bs-nl: Remove workaround for late .POSIX issue.
* tests/scripts/targets/POSIX: Add a comment.
* src/function.c (func_filter_filterout): Allocate arrays to hold
pattern and word information rather than creating linked lists on
the stack.
* tests/scripts/functions/filter-out: Test large filters.
Ensure that makefiles are rebuilt in the order in which make first
considered them, and document this behavior in the manual.
* NEWS: Add a note about the new behavior
* doc/make.text (How make Processes a Makefile): Document it.
* main.c (main): Inverse the list of makefile goals.
* read.c (read_all_makefiles): Add default makefiles to the list at
the front in reverse order, the same way other makefiles are added.
* tests/scripts/features/include: Add tests to verify rebuild order.
The "[" link may be missing during OS boostrapping.
* build.sh: Convert "[ ... ]" to "test ..."
* maintMakefile: Ditto.
* scripts/copyright-update: Ditto
* tests/scripts/features/reinvoke: Ditto
* tests/scripts/features/targetvars: Ditto
When using execvp() if $PATH is not present in the environment
it will automatically search the system default PATH string. Emulate
this by passing the system default PATH to find_in_given_path() if
we don't find PATH in the environment.
* src/job.c (child_execute_job): Use confstr(_CS_PATH) if PATH is not
found.
Rather than having an %extraENV that is added to the default %ENV
and resetting %ENV _before_ each test, allow the test setup to
modify %ENV directly as needed then reset %ENV _after_ each test.
* tests/test_driver.pl: Remove unused %extraENV.
(resetENV): Don't add in %extraENV.
(_run_command): Reset after we run the command rather than before.
* tests/scripts/features/export: Convert %extraENV to %ENV
* tests/scripts/features/jobserver: Ditto

* tests/scripts/variables/SHELL: Ditto
We want to process -C options as early as possible, before we might
write informational messages, so that Entering/Leaving messages have
the correct directory.
* src/main.c (main): Move code dealing with changing directories
before parsing of the jobserver auth flag.
* tests/scripts/features/jobserver: Test the order of enter/leave.
Previously if --no-print-directory was seen anywhere even once
(environment, command line, etc.) it would always take precedence
over any --print-directory option. Change this so that the last
seen option (which will be the command line, if present there) takes
precedence.
* NEWS: Mark this change in behavior.
* src/makeint.h (print_directory): A new variable to control printing.
* src/output.c (output_dump): Use the new variable.
(output_start): Ditto.
* src/main.c: Add a new variable print_directory. Use -1 for
print_directory_flag so we know of the option was seen or not. Add a
new default_print_directory_flag set to -1 to keep options from being
added.
(switches): Use flag_off for --no-print-directory, rather than a
separate inhibit_print_directory_flag.
(main): If print_directory_flag was set by the user, use that for
print_directory. If not, compute the print_directory value based on
-s, -C, and sub-makes as before.
* tests/scripts/variables/GNUMAKEFLAGS: -w is not added automatically
* tests/scripts/options/print-directory: Add tests for overriding
print-directory options.
POSIX says that suffix rules cannot have prerequisites, but after
making this change we observed a number of makefiles "in the wild"
that were relying on this behavior and failed.
For .POSIX: makefiles, obey POSIX. Otherwise preserve the old
behavior. However, generate a warning so users know this is a
problem. In a future version we will change all behavior to be
POSIX-conforming.
* NEWS: describe the change
* src/rule.c (convert_to_pattern): If posix_pedantic don't make a
pattern rule if prereqs exist. Otherwise show a warning.
* tests/scripts/features/suffixrules: Add tests for the new behavior
including .POSIX vs. non-.POSIX.
Initial implementation by Christof Warlich <cwarlich@gmx.de>
* NEWS: Announce the new feature.
* doc/make.texi (Other Special Variables): Document .EXTRA_PREREQS.
* src/dep.h (struct dep): New flag to note extra prereq deps.
* src/filedef.h (expand_extra_prereqs): Declare a function to expand
the value of .EXTRA_PREREQS.
* src/file.c (expand_extra_prereqs): Given a struct variable lookup
of .EXTRA_PREREQS, convert it into a list of deps and for each one
make sure it has a struct file and has the new flag set.
(snap_file): A new function invoked by hash_map that will perform
per-file operations: set up second expansion, intermediate, and also
.EXTRA_PREREQS. Manage circular dependencies by ignoring them.
(snap_deps): Defer per-file operations until the end. Look up the
global .EXTRA_PREREQS and pass it along to snap_file for each file.
* src/implicit.c (struct patdeps): Remember the extra prereqs flag.
(pattern_search): Transfer extra prereqs flag settings into the
matched pattern rule.
* src/rule.h (snap_implicit_rules): Rename count_implicit_rules to
snap_implicit_rules since we now do more than count.
* src/rule.c (snap_implicit_rules): As we walk through all the pattern
rules, add in any global .EXTRA_PREREQS to the dep list. Ensure we
take them into account for the max number of prereqs and name length.
* src/main.c (main): Add extra-prereqs to .FEATURES.
Call the renamed snap_implicit_rules.
* tests/scripts/variables/EXTRA_PREREQS: Add tests.
Avoid using posix_spawn implementations that fail asynchronously when
the spawned program can't be invoked: this means instead of getting
an error such as "No such file or directory" we get just "Exit 127".
Original implementation of the configure.ac macro provided by
Martin Dorey <martin.dorey@hds.com>
Original implementation of the regression tests provided by
Dmitry Goncharov <dgoncharov@users.sf.net>
* configure.ac: Test whether posix_spawn fails asynchronously. In a
cross-compilation environment, assume that it does not. If we detect
that it does, fall back to fork/exec.
* tests/scripts/features/exec: Add regression tests for different
shebang invocation methods.
* src/dep.h: Add a new flag PARSEFS_ONEWORD
* src/read.c (parse_file_seq): If PARSEFS_ONEWORD is given, treat the
entire incoming string as a single pattern.
* src/implicit.c (pattern_search): Pass PARSEFS_ONEWORD when parsing
patterns for wildcards.
* tests/scripts/features/patternrules: Add a new test.
If the stem matches a path containing a directory not just a
filename, make sure the second expansion of $* in the
prerequisites matches $* in the recipe. This requires using
$(*F) when replacing % in the first expansion to preserve the
simple filename.
* src/implicit.c (pattern_search): If lastslash is set prepend
the directory onto the stem. Then use $(*F) when expanding %.
* tests/scripts/features/se_implicit: Add a test case
On Windows the path to the helper tool will contain '\': this will
fail if recipes are run with a POSIX shell. Convert '\' to '/'
on Windows. While here, escape any spaces in the path as well.
* tests/thelp.pl: Rename from tests/jhelp.pl.
(op): Use names instead of options for the operations.
(op): Add new operations for sleep, mkdir, and rm.
(op): Enhance wait to time out
* tests/run_make_tests.pl: Add a new #HELPER# replacement
(subst_make_string): Use fully-qualified path to thelp.pl
* tests/scripts/features/parallelism: Update to use thelp.pl
and the new named operations. Use thelp.pl sleep instead of
system-specific sleep commands.

This reverts commit 6264deece3.
Further investigation discovers that the real issue is that
GNU Emacs compile mode doesn't have a matching regex for GNU
make error messages generated when targets fail. I submitted
a patch to GNU Emacs adding a matcher for compile mode.
Ensure we properly reduce job_slots_used if a command fails because
it doesn't exist/can't be started.
* src/job.h (struct child): Add a field jobslot to be set when using
a job slot.
* src/job.c (start_waiting_job): Remember if we are using a job slot.
(reap_children): Reduce number of job slots used by jobslot.
Go through both run_make_tests.pl and test_driver.pl and slightly
modernize the Perl and clean up indentation etc. Fix a number of
warnings in the test scripts detected by running with -w.
* tests/test_driver.pl: Move make error string detection out of the
base test driver.
(run_all_tests): Ensure that we always look for tests in the cwd.

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.
The built-in glob implementation does not correctly handle dangling
symlinks. This needs to be fixed by switching to the latest glob
implementation from gnulib but that's a big job: for now avoid the
test if we know it will fail.
The check for matching a file's command to the default rule's command
does not account for null. If no .DEFAULT is defined a rule with no
recipe has it's $< variable set to the value of $@. This breaks second
expansion, particularly when used with pattern rules.

Ensure that variable overrides are passed to recursive make instances
even if no overrides were provided on the command line.
Fix suggested by Rici Lake <ricilake@gmail.com>
* src/main.c (define_makeflags): Add overrides without respect to the
value of command_variables.
* tests/scripts/features/recursion: Add a test.
When merging the variable_set_lists for two targets it could be
that the "from" set list is a subset of the "to" set list: check
for this situation to avoid freeing used memory.
* src/variable.c (merge_variable_set_lists): Walk the "to" list and
if the "from" list is contained in it, nothing to do.
* tests/scripts/features/se_explicit: Add a test.
Create a new variable run_silent to hold the current instance's global
silence setting, allowing silent_flag to represent only whether the -s
option was provided on the command line.
* src/makeint.h: Change silent_flag variable to run_silent.
* src/job.c: Ditto.
* src/remake.c: Ditto.
* src/file.c: Ditto.
* src/main.c: Add a new global variable run_silent.
(decode_switches): After switches are decoded, initialize run_silent.
* tests/scripts/targets/SILENT: Add a test for recursive behavior.
This patch allows "grouped targets" using the &: syntax:
tgt1 tgt2 ... tgtn &: pre1 pre2 ...
recipe
When the &: separator is used (in single or double colon forms), all
the targets are understood to be built by a single invocation of the
recipe. This is accomplished by piggy-backing on the already-existing
pattern rule feature, using the file's "also_make" list.
* NEWS: Add information about grouped targets.
* doc/make.texi (Multiple Targets): Add information on grouped targets.
(Pattern Intro): Refer to the new section to discuss multiple patterns.
* src/main.c (main): Add "grouped-targets" to .FEATURES
* src/read.c (make_word_type): Add new types for &: and &::.
(eval): Recognize the &: and &:: separator and remember when used.

If so, update also_make for each file to depend on the other files.
(get_next_mword): Recognize the &: and &:: word types.
* tests/scripts/features/grouped_targets: New test script.
* AUTHORS: Add Kaz Kylheku
Fixes an issue seen in the Linux kernel build system, reported by
Masahiro Yamada <yamada.masahiro@socionext.com>. Fix suggested
on the bug-make mailing list by Mike Shal <marfey@gmail.com>.
* tests/scripts/features/parallelism: Add a test to verify this.
* NEWS: Update with a backward-compatibility warning.
* src/rule.c (convert_to_pattern): If a suffix rule has dependencies,
do not create a pattern rule for it. According to the manual suffix
rules with prerequisites are treated as normal targets.
* tests/scrips/features/suffixrules: Create some regression tests for
.SUFFIXES and suffix rules.
If multiple pattern rules have the same pattern as also-make targets
and we attempt to run them at the same time, we might downgrade the
command state from 'running' to 'deps_running'; this will prevent
that also_make from being considered complete causing make to wait
forever for it to finish.
Ensure that set_command_state never downgrades the state of a target.

existent commands and new error message formats.

* tests/scripts/functions/shell: Ditto.
If we failed to fork() we were essentially exiting make immediately
without respect to ignore flags, etc. On one hand that makes sense
because if you can't fork you're in real trouble, but it doesn't
work so well on systems where we don't fork at all. Instead, treat
a fork error like any other error by delaying the handling until
the next call to reap_children(). Any child with a PID of -1 is
considered to have died before starting so check these first without
waiting for them.
* src/commands.c (fatal_error_signal): Don't kill children that
never started.
* src/function.c (func_shell_base): Handle cleanup properly if the
child doesn't start.

starting and handle them without waiting for the PID.
(start_job_command): Free memory when the child doesn't start.
(start_waiting_job): Don't manage children who never started.
(child_execute_job): If the fork fails return PID -1.

Over time the non-standard build and install systems (nmake files,
smake files, Visual Studio project files, etc.) have atrophied and
maintaining them is not worth the effort, for such a simple utility
as make. Remove all the non-standard build tool support and unify
OS-specific build rules under a basic set of (GNU make) makefiles.
Preserve the existing bootstrapping scripts (for POSIX, Windows,
and MS-DOS). Also the existing VMS build scripts are left unchanged:
I don't have enough experience with VMS to venture into this area.
Perhaps one of the VMS maintainers might like to determine whether
conversion would be appropriate.
Rather than create libraries for w32 and glob (non-POSIX), simply
link the object files directly to remove the complexity.
* NEWS: Update with user-facing notes.

This is about twice as fast as the current hash, and removes the
need for double hashing (improving locality of reference). The
hash function is based on Bob Jenkins' design, slightly adapted
wherever Make needs to hash NUL-terminated strings. The old hash
function is kept for case-insensitive hashing.
This saves 8.5% on QEMU's no-op build (from 12.87s to 11.78s).

(get_osname): Compute the $port_type here. Add more $osname checks
for different Windows Perl ports.
(_run_command): Rewrite the timeout capability to work properly
with Windows. Don't use Perl fork/exec; instead use system(1,...)
which allows a more reliable/proper kill operation.
Also, allow options to be given as a list instead of a string, to
allow more complex quoting of command-line arguments.
* tests/run_make_tests.pl (run_make_with_options): Allow options
to be provided as a list in addition to a simple string.
(set_more_defaults): Write sample makefiles and run make on them
instead of trying to run echo and invoking make with -f-, to avoid
relying on shell and echo to get basic configuration values. Also
create a $sh_name variable instead of hard-coding /bin/sh.

* NEWS: Add information about the new option.
* read.c (eval_makefile): Set deps->error if we discovered any

The fix for SV 44742 had a side-effect that some double-colon targets
were skipped. This happens because the "considered" facility assumed
that all targets would be visited on each walk through the dependency
graph: we used a bit for considered and toggled it on each pass; if
we didn't walk the entire graph on every pass the bit would get out
of sync. The new behavior after SV 44742 might return early without
walking the entire graph. To fix this I changed the considered value
to an integer which is monotonically increasing: it is then never
possible to incorrectly determine that a previous pass through the
graph already considered the current target.
* filedef.h (struct file): make CONSIDERED an unsigned int.
* main.c (main): No longer need to reset CONSIDERED.
* remake.c (update_goal_chain): increment CONSIDERED rather than
inverting it between 0<->1.
(update_file_1): Reset CONSIDERED to 0 so it's re-considered.
(check_dep): Ditto.
* tests/scripts/features/double_colon: Add a regression test.
* remake.c (update_file): Don't update double-colon target status
if we're still building targets.

* dep.h (struct dep): Don't reuse "changed"; make a separate field
to keep "flags". Get rid of dontcare and use the flag.
(struct goaldep): Create a new structure for goal prereqs
that tracks an errno value and the floc where the include happened.
Rework the structures to ensure they are supersets as expected.
In maintainer mode with GCC, use inline to get type checking.

Previously if the jobserver was active, MAKEFLAGS would contain only
the -j option but not the number (not -j5 or whatever) so users
could not discover that value. Allow that value to be provided in
MAKEFLAGS without error but still give warnings if -jN is provided
on the command line if the jobserver is already activated.
* NEWS: Discuss the new behavior.
* os.h, posixos.c, w32/w32os.c: Return success/failure from
jobserver_setup() and jobserver_parse_auth().
* main.c (main): Separate the command line storage of job slots (now
in arg_job_slots) from the control storage (in job_slots). Make a
distinction between -jN flags read from MAKEFLAGS and those seen
on the command line: for the latter if the jobserver is enabled then
warn and disable it, as before.
* tests/scripts/features/jobserver: Add new testing.
* NEWS: Mention the change.
* main.c: Rename jobserver_fds variable to jobserver_auth and
--jobserver-fds option to --jobserver-auth.

For performance, we only recompute .VARIABLES when (a) it's expanded
and (b) when its value will change from a previous expansion. To
determine (b) we were checking the number of entries in the hash
table which used to work until we started undefining entries: now if
you undefine and redefine the same number of entries in between
expanding .VARIABLES, it doesn't detect any change. Instead, keep
an increasing change number.
* variables.c: Add variable_changenum.
(define_variable_in_set, merge_variable_sets): Increment
variable_changenum if adding a new variable to the global set.
(undefine_variable_in_set): Increment variable_changenum if
undefining a variable from the global set.

* job.h (struct child): New bit to mark recursive command lines.
* job.c (start_job_command): Set the recursive command line bit.
(reap_children): If the child is a recursive command and it exits
with 1 during question mode, don't print an error and exit with 1.
* tests/scripts/options/dash-q: Add a regression test.
Newer versions of binutils allow ar to be compiled to generate
"deterministic archives" by default: in this mode no timestamp
information is generated in the static archive, which utterly
breaks GNU make's archive updating capability. Debian and Ubuntu
have turned this feature on by default in their distributions
which causes the regression tests to fail.
Update the regression tests to check for the availability of the
"U" option to ar which disables deterministic archives and allows
GNU make's archive support to work properly again.
In order to fix SV 12267 we were marking the prerequisites of
implicit (pattern) targets that existed elsewhere in the makefile
as precious to keep them from being deleted as intermediate files.
However this also keeps them from being deleted on error. Instead
mark them as secondary.
* tests/scripts/targets/DELETE_ON_ERROR: Test DELETE_ON_ERROR.
Add a new variable .SHELLSTATUS which holds the exit status of the
last-invoked shell function or != assignment.
* NEWS, doc/make.texi: Document the change.

Rename existing ChangeLog files so they won't be distributed.
Add targets to maintMakefile to generate ChangeLog from the Git
repository. This will require a version of gnulib be available.
Because ChangeLog is auto-generated, we have to switch our
automake mode to "foreign" or it will complain and fail.
Expand the characters which are legal in a function name, and check
the name for validity. Create a type for the function pointer.
Convert the last argument from a boolean to flags, to allow for expansion.
Don't dup stdout into stderr in the test suite.
Don't rely on $port_type eq "UNIX" to mean case-preserving.
Check against the real output of ar when creating archives.
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.
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.
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.
