- variable_expand -> expand_string
- variable_expand_string -> expand_string_buf
- variable_expand_for_file -> expand_string_for_file

- allocated_variable_expand_for_file ->
allocated_expand_string_for_file

The indentation shown in debug output was misleading. Increment the
depth when we are working on a prerequisite, not for the current
target.
* src/remake.c (check_dep): Increment depth only on recursion.

still running.

search.

by hand.

Fix .NOTINTERMEDIATE without prerequisites to disable intermediate
status for all targets.
* src/makeint.h: Declare extern no_intermediates.
* src/main.c: Add global definition of no_intermediates.
* src/file.c: Remove static no_intermediates to use global variable.
(remove_intermediates): Check no_intermediates.
* src/implicit.c (pattern_search): For a file found by implicit search
set file->notintermediate if no_intermediates is set.
* src/remake.c (update_file_1): Don't set file->secondary for a
pre-existing file if no_intermediates is set. The check for
no_intermediates here is redundant, but won't hurt: keep it in case
things change so that it matters.
* tests/scripts/targets/NOTINTERMEDIATE: Fix a test.

If any of a set of grouped targets is missing or out of date, even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().

The next version of the POSIX standard defines parallel execution
and requires the .WAIT special target as is implemented in some other
versions of make.
This implementation behaves similarly to others in that it does not
create a relationship between targets in the dependency graph, so
that the same two targets may be run in parallel if they appear as
prerequisites elsewhere without .WAIT between them.
Now that we support .WAIT it's trivial to also support prerequisites
of the .NOTPARALLEL special target, which forces the prerequisites of
those targets to be run serially (as if .WAIT was specified between
each one).
* NEWS: Announce the new .WAIT and .NOTPARALLEL support.
* doc/make.texi (Parallel Disable): A new section to discuss ways in
which parallel execution can be controlled. Modify cross-refs to
refer to this section.
* src/dep.h (struct dep): Add a new wait_here boolean.
(parse_file_seq): Add PARSEFS_WAIT to check for .WAIT dependencies.
* src/file.c (split_prereqs): Use PARSEFS_WAIT.
(snap_deps): If .NOTPARALLEL has prerequisites, set .WAIT between
each of _their_ prerequisites.
(print_prereqs): Add back in .WAIT when printing prerequisites.
* src/implicit.c (struct patdeps): Preserve wait_here.
(pattern_search): Ditto. Use PARSEFS_WAIT when parsing prereqs for
pattern rule expansion.
* src/read.c (check_specials): Don't give up early: remembering to
update these options is not worth the rare speedup.
(check_special_file): If .WAIT is given as a target show an error--
once--if it has prereqs or commands.
(record_files): Call check_special_file on each target.
(parse_file_seq): If PARSEFS_WAIT is given, look for .WAIT prereqs.
If we see one assume that we are building a struct dep chain and set
the wait_here option while not putting it into the list.
* src/remake.c (update_file_1): If wait_here is set and we are still
running, then stop trying to build this target's prerequisites.
* src/rule.c (get_rule_defn): Add .WAIT to the prerequisite list.
* src/shuffle.c (shuffle_deps): Don't shuffle the prerequisite list
if .WAIT appears anywhere in it.
* tests/scripts/targets/WAIT: Add a test suite for this feature.

Introduce non-deterministic ordering into goal and prerequisite
traversal to help tease out inconsistent failures that may happen
when running in parallel build mode.
Introduce second order into each dependency chain:
1. Existing order is syntactic order reachable via 'dep->next'
2. New order is shuffled order stored as 'dep->shuf' in each 'dep'
When updating goals and prerequisites and '--shuffle' is provided,
use the shuffled order to walk the graph. When automatic variable
are set always use the syntactic order of parameters.
* Makefile.am: Add new src/shuffle.c and src/shuffle.h file.
* build_w32.bat: Ditto.
* builddos.bat: Ditto.
* makefile.com: Ditto.
* po/POTFILES.in: Ditto.

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.

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.

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.

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.

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.

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.

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.
* src/main.c (main): Add "notintermediate" to the .FEATURES variable.
* src/filedef.h (struct file): Add "notintermediate" flag.
* src/file.c (no_intermediates): Mark global .NOTINTERMEDIATE.
(snap_file): Support .NOTINTERMEDIATE special target. Throw an error
if the same target is marked both .NOTINTERMEDIATE and .SECONDARY or
.INTERMEDIATE.
(rehash_file): Merge intermediate, notintermediate, secondary flags.
(remove_intermediates): Check notintermediate flag before removing.
(print_file):
* src/implicit.c (pattern_search): Set notintermediate based on the
pattern.
* tests/scripts/targets/NOTINTERMEDIATE: Add a new test suite.

Initial implementation by Christof Warlich <cwarlich@gmx.de>
* NEWS: Announce the new feature.
* doc/make.texi (Other Special Variables): Document .EXTRA_PREREQS.

* 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.

|
|
|
|

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
|
|
|
|
|
|
| |
If filename contained multiple slashes lastslash is wrongly set to 0.
* configure.ac: Check for the GNU memrchr() extension function.
* src/misc.c (memrchr): Supply memrchr() if not available.
|
| |
|
| |
|
|
|
|
|
| |
* Convert integer types to size_t where necessary.
* Align other integral types to avoid casts and type warnings.
|
| |
|
|
Move the source code (other than glob) into the "src" subdirectory.
Update all scripting and recommendations to support this change.
* *.c, *.h, w32/*: Move to src/
* configure.ac, Makefile.am, maintMakefile: Locate new source files.
* Basic.mk.template, mk/*: Update for new source file locations.
