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.
This allows you to write portable makefiles that set GNU make-specific command
line options in the environment or makefile: add them to GNUMAKEFLAGS instead
of MAKEFLAGS and they will be seen by GNU make but ignored by other
implementations of make.
This mode replaces the previous heuristic setting enabled with -O, where we
would log directory enter/leave for each synchronized output. Now we only
do that if --trace=dir is given.
If output-sync is enabled, have make write the command line to the temp file
instead of printing it directly to the screen to ensure that the output is
ordered properly. Also, remove extraneous enter/leave operations by having
them printed directly when dumping temp file output.
If we are not going to sync a command line then dump any collected output
first to preserve ordering. Do some code cleanup:
* Move the handle init to a separate function.
* Move the temp file truncation to the output function.
* Remember whether we sync in a variable for readability.
* Handle EINTR and short writes in child_out().
* Always call sync_output() in case output_sync was changed due to error.
load.c (load_object, load_file): Accept an additional argument
DLP and return in it a pointer that can be used to unload the
dynamic object.
read.c (eval): Call load_file with an additional argument, and
record the pointer returned there in the 'struct file' object of
dynamic objects in that object's 'struct file'.
commands.c (execute_file_commands): Unload dynamic objects
before remaking them, to avoid failure to remake if the OS doesn't
allow overwriting objects that are in use.
filedef.h (struct file): New member dlopen_ptr.
gnumake.h (GMK_EXPORT): Define to dllexport/dllimport
decorations for Windows and to nothing on other platforms.
(gmk_eval, gmk_expand, gmk_add_function): Add GMK_EXPORT qualifier
to prototypes.
makeint.h (MAIN): Define before including gnumake.h, to give
correct dllexport decorations to exported functions.
(load_file): Adjust prototype.
loadapi.c: Don't include gnumake.h, since makeint.h already
includes it, and takes care of defining MAIN before doing so.
build_w32.bat (LinkGCC): Produce an import library for functions
exported by Make for loadable dynamic objects.
w32/compat/posixfcn.c (dlclose): New function.
w32/include/dlfcn.h (dlclose): Add prototype.
scripts/features/load: Fix signatures of testload_gmk_setup and
explicit_setup, to bring them in line with the documentation.
Enhance the child_error() function so that it will write error output to the
child's sync output buffer, if it exists. If it doesn't the output goes to
stdout/stderr.
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.
Provide a simple API for loaded objects to interact with GNU make. I still
won't guarantee that this API won't change but it's much closer to something
that's supported and provides easy-to-use interfaces with a public header
file.
We fixed Savannah 16670 but that broke previously-working makefiles
that relied on the GNU make behavior. The POSIX behavior doesn't
seem to me to be better, and can be obtained using GNU make as well,
so put it back as the default behavior and require .POSIX to
get the POSIX behavior.
Add a new section to the manual discussing backslash/newline handling.
Update the test suite.
On configure-enabled systems, configure will detect Guile installed
(using pkg-config, which is how GNU Guile is distributed) and enable
it if so.
On all non-configure-enabled systems, currently, the default is for
Guile support to be disabled.
and store them in static variables; however one value (std_dirs)
was not being stored statically so the second time through it was
not set.
Fixes Savannah bug #32511
backward-incompatible change in the 2008 POSIX specification.
- Add the .SHELLFLAGS variable so people can choose their own shell flags.
- Add tests for this.
- Add documentation for this.
- Fix memory errors found by valgrind
- Remove multi_glob() and empower parse_file_seq() to do its job:
the goal here is to remove the confusing reverse/re-reverse we do on
the file lists: needed for future fixes.
- Add a prefix arg to parse_file_seq()
- Make concat() variadic so it can take arbitrary #'s of strings
- Fix Savannah bug #17752
- Test suite:
* When tests fail keep a "run" file containing the command invoked.
* Support for the Valgrind "memcheck" and "massif" tools.
Allows the user to reset the prefix character for introducing recipe lines
from the default (tab) to any other single character, and back again.
Also, reworked the manual to consistently use the word "recipe" to describe
the set of commands we use to update a target, instead of the various
phrases used in the past: "commands", "command lines", "command scripts",
etc.
One of our translations disappeared from the translations site so remove it.
The fdl.texi file was changed to not contain any @node entries, so add some
around it in make.texi.
Add a new feature to the test suite suggested by Icarus Sparry:
set a timer before invoking a test, so that if it loops infinitely we
will wake up and have a chance to kill the process and continue.
string into the strcache. As a side-effect, many more structure members and
function arguments can/should be declared const.
As mentioned in the changelog, unfortunately measurement shows that this
change does not yet reduce memory. The problem is with secondary expansion:
because of this we store all the prerequisites in the string cache twice.
First we store the prerequisite string after initial expansion but before
secondary expansion, then we store each individual file after secondary
expansion and expand_deps(). I plan to change expand_deps() to be callable
in either context (eval or snap_deps) then have non-second-expansion
targets call expand_deps() during eval, so that we only need to store that
dependency list once.

Plus some from the mailing list.
Imported a patch from Eli to allow Cygwin builds to support DOS-style
pathnames.
Update NEWS docs.
Enhance the manual to use automake version.texi, and use the canonical
FSF copyright features and statement.
Some $(realpath ...) tests won't work on Windows; leave them out
The jobserver filedescriptor test might fail if some FDs are reserved,
so for now comment out that check.
Revert a fix for $? including non-existent files as it shows a bug
in the Linux kernel build. Give them a release to fix this.
Add some changes from Eli Z. for Windows changes.
I decided this feature was too impacting to make the permanent default
behavior. This set of changes makes the default behavior of make the
old behavior (no second expansion). If you want second expansion, you
must define the .SECONDEXPANSION: special target before the first target
that needs it.
This set of changes ONLY fixes explicit and static pattern rules to work
like this. Implicit rules still have second expansion enabled all the
time: I'll work on that next.
Note that there is still a backward-incompatibility: now to get the old
SysV behavior using $$@ etc. in the prerequisites list you need to set
.SECONDEXPANSION: as well.
follow POSIX backslash/newline conventions.
Use a different method for testing the SHELL variable, which hopefully
will work better on non-UNIX systems.
Solaris system with an EMC NFS storage solution. Still get some odd
errors here unfortunately related to sub-second timestamps that I just
can't figure out. It all works if we run the tests in /tmp instead
though :-/.
check for this and exit with an error.
The closeout.c version from gnulib pulls in too much other stuff, and
gnulib requires an ANSI C 89 compliant compiler, while GNU make (so far)
still wants to work on K&R.
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...
* New function: $(info ...)
* Disallow $(eval ...) to create prereq relationships inside command scripts
(caused core dumps)
* Try to allow more tests to succeed in Windows/DOS by sanitizing CRLF and \
* Various bug fixes and code cleanups (see the ChangeLog entry)
Fix references to MINGW #define constants.
Remove WINDOWS32 ifdef from sub_proc.h.
Only add variables to the command line for recursion once.
New features in run_make_test: #PWD# and #MAKEPATH# replacements.
Test the multi-variable fix in the recursion regression test.
POSIX requires that the value of SHELL in the makefile NOT be exported
to sub-commands. Instead, the value in the environment when make was
invoked should be passed to the environment of sub-commands. Note that
make still uses SHELL to _run_ sub-commands; it just doesn't change the
value of the SHELL variable in the environment of sub-commands.
As an extension to POSIX, if the makefile explicitly exports SHELL then
GNU make _will_ use it in the environment of sub-commands.
reported by Markus Mauhart <qwe123@chello.at>. One was a simple typo; to
fix the other we call patsubst_expand() for all instances of variable
substitution, even when there is no '%'. We used to call subst_expand()
with a special flag set in the latter case, but it didn't work properly
in all situations. Easier to just use patsubst_expand() since that's
what it is.
- Apply a fix for the "thundering herd" problem when using "-j -l".
This also fixes bug #4693.
- Fix bug #7257: allow functions as ifdef arguments
- Fix bug #4518: make sure we print all double-colon rules with -p.
- Upgrade to autconf 2.58/automake 1.8/gettext 0.13.1
- Various doc cleanups, etc.
Implemented enhancement #1391: allow "export" in target-specific
variable definitions.
Change the Info name of the "Automatic" node to "Automatic Variables".
Add text clarifying the scope of automatic variables to that section.
* Never use "touch" in make rules; it breaks on most sub-second
supporting systems. Use echo "" > $@ instead.
* Forgot to close test makefiles before using them!
All the above worked fine on Linux but failed miserably on Solaris.
GNU make. Also he provides some other performance fixups after doing
some profiling of make on large makefiles.
Modify the test suite to allow the use of Valgrind to find memory problems.
Incorporate "order-only" prerequisites patch. Wrote a test for it.
The test shows what might be a bug in the code; I need to look at it
more closely (anyway it doesn't behave as I expected). Also I haven't
done the docs yet.
New version of the manual, put into the doc subdir.
Enhancements: $(eval ...) and $(value ...) functions, various bug
fixes, etc. See the ChangeLog.
More to come.
properly.
Fix configure: allow cross-compilation; fix getloadavg (still needs _lots_
of work!)
Let $(call ...) functions to be self-referencing. Lets us do transitive
closures, for example.
* Define COFLAGS to avoid unknown variable warning.
* Fix some usec problems on UnixWare.
* Don't remove .INTERMEDIATE targets specified on the command line.
