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.
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.
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.
(record_files): Accept an indicator of whether the rule is grouped.
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
There's no need to frighten users away from capabilities which are
perfectly reasonable and definitely not going away, by calling them
obsolete or discouraged in the manual.
* doc/make.texi (Appending): Document this behavior.
* variable.c (do_variable_definition): Only add a space if the variable
value is not empty.
* tests/scripts/variables/flavors: Test this behavior.
* make.1: Document the -E and --eval options.
* doc/make.texi: Document the -E option.
* tests/scripts/options/eval: Test the -E option and MAKEFILES.
* NEWS: Add information about the new option.
* make.1: Document the new flag.
* doc/make.texi: Document the new flag. Remove suggestions that the
.SILENT special target is deprecated or should not be used.
* tests/scripts/options/dash-s: Test the -s and --no-silent options.
* NEWS: Add information about the new option.
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: Add information about reading files.
* make.texi (File Function): Describe reading files.
* tests/scripts/functions/file: Test new features for $(file ...)
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.
* function.c (shell_completed, msdos_openpipe, func_shell_base): Add
shell_completed() to handle the completion of the shell, by setting
.SHELLSTATUS. Call it where needed.
* job.c (child_handler): Call shell_completed().
* tests/scripts/functions/shell: Add tests for .SHELLSTATUS.
* configure.ac: Test for isatty() and ttyname()
* makeint.h: provide a substitute for ttyname() if it's not available.
* config.ami.template, config.h-vms.template, config.h.W32.template:
define/undefine HAVE_ISATTY/HAVE_TTYNAME macros.
* NEWS, doc/make.texi: Document these new variables.
Reported by Tim Murphy <tnmurphy@gmail.com>
* function.c (func_file): Only write TEXT if it is not NULL.
* NEWS, doc/make.texi: Document the new feature
* tests/scripts/functions/file: Verify that the no-text version of
$(file ...) works and doesn't add a newline.
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.
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.
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.
