* src/read.c (make_word_type): Remove w_varassign from the enum.
(get_next_mword): This function is never called on a string in a place
where we might find a variable assignment. Any variable assignments
have already been handled via try_variable_definition(), so we don't
need to check for them here.
* tests/scripts/variables/flavors: Check triple-colon assignment in
target-specific variables.
* README.git: Add some notes about using ASAN.
* src/makeint.h: Declare skip_references().
* src/misc.c (skip_reference): A new function that will skip over a
variable reference, counting matching open paren/brace characters.
* src/implicit.c (get_next_word): Replace code with skip_reference().
* src/read.c (conditional_line): Ditto.
(find_map_unquote): Ditto.
(get_next_mword): Ditto.
(parse_variable_definition): Ditto.
* src/function.c (handle_function): Make clear that the passed in
pointers are not modified if the function returns false.
* src/expand.c (expand_string_buf): Don't create local variables to
call handle_function() since it doesn't modify its arguments.
* src/job.c (new_job): Small simplifications.
Reported-by: MIAOW Miao <guoyr_2013@hotmail.com>
Patch from: Henrik Carlqvist <hc981@poolhem.se>
Test from: Dmitry Goncharov <dgoncharov@users.sf.net>
* src/expand.c (recursively_expand_for_file): Check the variable name
before checking for equality so we don't overrun the buffer.
* tests/scripts/functions/shell: Add a test with a very long variable.
Add an option to print a list of targets defined in the makefiles.
Don't print targets of implicit rules, or special targets. To
support this remember which files are deemed suffix rule targets.
Add a missing warning for single-suffix targets with prerequisites.
Suggested by many. Sample implementation by Tim <tdhutt@gmail.com>.
* NEWS: Announce the new option and single-suffix warning.
* doc/make.1: Add --print-targets to the man page.
* doc/make.texi: Add --print-targets to the documentation. Clean up
the text around the definition of suffix rules.
* src/main.c (print_targets_flag): New variable for --print-targets.
(switches): Add a new long option --print-targets.
(main): If the option was provided call print_targets() and exit.
* src/filedef.h (struct file): Add a "suffix" boolean value. Remove
print_prereqs() since it's static. Add new print_targets().
* src/file.c (rehash_file): Merge the new suffix value.
(print_prereqs): Used only locally: change to static.
(print_target): Print targets which are not suffix rule targets and
are not special targets.
(print_targets): Call print_target() on each file.
* src/rule.c (convert_to_pattern): Make maxsuffix local; it doesn't
need to be static. Emit ignoring prerequisites for single-suffix
rules as well as double-suffix rules. Remember which files are
actually suffix rules.
* tests/scripts/features/suffixrules: Test single-suffix behavior.
* tests/scripts/options/print-targets: Add tests for --print-targets.
Ensure that we correctly skip the entirety of a macro or function
reference when searching for the "," separator in an ifeq/ifneq
conditional, including using "$," and also "${foo,bar}". Note that
this change means that parenthesis OTHER than those used for variable
expansion are not considered special, any longer.
* NEWS: Announce the change.
* src/read.c (conditional_line): Skip variable references when looking
for "," and ensure that we match closing parens/braces properly.
* tests/scripts/features/conditionals: Add tests for this behavior.
* src/rule.c (snap_implicit_rules): Set need_2nd_expansion of each
prerequisite of global .EXTRA_PREREQS.
* src/file.c (snap_file): Set need_2nd_expansion of each prerequisite
of target-specific .EXTRA_PREREQS.
* tests/scripts/variables/EXTRA_PREREQS: Add tests.
Reported by Daniel Gerber <dg@atufi.org>.
Trick the compiler by hiding the cast in a function call.
* src/os.h: Declare the new function.

(fd_noinherit): Ditto.
* src/function.c (windows32_openpipe): Ditto.
* src/w32/compat/posixfcn.c (isatty): Ditto.
* src/w32/subproc/sub_proc.c (process_easy): Ditto.
If a resource compiler is available, use it to add a UTF-8 resource
to the GNU Make executable on Windows. As a result, GNU Make will
use UTF-8 as its ANSI code page, enabling it to work with UTF-8
encoded Makefiles, understand UTF-8 paths passed to it, etc.
These build process changes apply to all 3 ways that GNU Make can
be built for Windows:
1) configure
2) Basic.mk
3) build_w32.bat
When building with Visual Studio the resource compiler should always
be available.
When building with GCC or TCC, it depends on the availability of
'windres'.
If a resource compiler is not available, don't fail the build but
just proceed without the UTF-8 resource, effectively ignoring this
feature.
The UTF-8 resource only has an effect when GNU Make is running on a
minimum target version of Windows Version 1903 (May 2019 Update).
When the built GNU Make is running on an earlier version of Windows,
the embedded UTF-8 resource has no effect.
Code page information is added to --version output to tell users what
code pages are being used by any combination of GNU Make build (with
or without the UTF-8 resource) and Windows version that GNU Make is
running on (earlier than 1903 or not).
* README.git: Fix a typo.
* configure.ac: Search for windres and set WINDRES / HAVE_WINDRES.
* Makefile.am: Add manifest and resource files to EXTRA_DIST and
add a windres invocation to build them.
* build_w32.bat: Add support to build resource files.
* src/main.c (print_version): Add codepage info to Windows output.
* src/w32/utf8.manifest: Add a windres manifest file.
* src/w32/utf8.rc: Add a windres resource file.
* Basic.mk.template: Add support for building resource files.
* mk/Windows32.mk: Support windres resource files.
* .gitignore: Ignore TCC output directories.
Modify areas dealing with large command lines to use the heap rather
than relying on alloca / stack space.
* src/main.c (main): Allocate potentially large buffers with xmalloc.
(decode_env_switches): Ditto.
* src/function.c (func_error): Replace alloca with xmalloc/free.
* tests/scripts/features/expand: Add a newline for readable diffs.
* NEWS: Mention this change.
* src/read.c (eval): Check for ignoring for any line even if not
in a rule context.
* tests/scripts/features/conditionals: Write new tests.
Without this patch, the output of 'make -p' would generate output that
sometimes incorrectly implied that the clock jumped backwards.
* src/main.c (time_now): New function.
(print_data_base): Use it.
If a loaded object defines a symbol <object>_gmk_unload, assume it's
a function and invoke it whenever the loaded object is unloaded.
Original implementation by Dmitry Goncharov <dgoncharov@users.sf.net>
* NEWS: Announce the change.
* doc/make.texi: Describe the behavior.
* src/gnumake.h: Add information to the comments.
* src/makeint.h (unload_all): Declare a new function.
* src/main.c (die): Invoke unload_all().
* src/load.c (unload_func_t): Declare a new type for unload.
(struct load_list): Remember the unload symbol if it exists.
(load_object): Move the parsing of the object name from load_file.
Check for the _gmk_unload symbol and if found, remember it.
(load_file): Allow load_object to do object filename parsing.
(unload_file): Remove the load_list entry when unloading the object.
(unload_all): Unload all the loaded objects.
* tests/scripts/features/loadapi: Test the unload function.
Add an ABI version both to the header file and passed to the setup
function. Unfortunately this itself is an ABI break and I couldn't
find a good way to avoid it.
* NEWS: Announce the ABI is not a preview and the incompatibility.
* doc/make.texi: Remove the preview warnings for object loading.
Document the new ABI version argument.
* src/gnumake.h (GMK_ABI_VERSION): Set the ABI version to 1.
Add comments documenting the format of the setup function.
* src/load.c (setup_func_t): Rename from load_func_t.
(load_file): Pass the ABI version to the setup function.
* tests/scripts/features/load: Rework the setup function.
* tests/scripts/features/loadapi: Ditto.
Previously "load:" worked but "load :" failed. Allow the latter as
well. This doesn't fix all issues; "load foo :" is still treated
as a load operation for "foo" and ":". Avoids SV 50413 as well.
* tests/scripts/features/load: Write tests.
When the expanded value of the variable in buf occupies more space
than available in variable_buffer, function variable_buffer_output
reallocates variable_buffer: return a pointer into the new memory,
not the old memory.
* src/expand.c (expand_variable_buf): Preserve the offset of buf and
return that offset into the (potentially reallocated) buffer.
* tests/scripts/features/expand: Add tests.
Disable builtin variables and rules immediately, when -R or -r is
added to MAKEFLAGS inside the makefile.
* src/main.c (disable_builtins): Add new function disable_builtins().
(main): Call disable_builtins().
(reset_makeflags): Call disable_builtins().
* tests/scripts/options/dash-r: Add tests.
* tests/scripts/variables/MAKEFLAGS: Update tests.
Avoid compiler warnings on Windows by moving local headers after
system headers.
* src/job.c: Move all headers other than makeint.h.
* src/main.c: Ditto.
* src/read.c: Ditto.
