* maintMakefile: Add a rule to submit code for analysis.
* configure.ac: Check for availability of the umask() function.
* output.c (output_tmpfd, output_tmpfile): Use umask on temp files.
* makeint.h (PATH_VAR): Reserve an extra character for nul bytes.
* function.c (func_error): Initialize buffer to empty string.
* job.c (child_execute_job): Verify validity of fdin.
* main.c (main): Simplify code for makefile updating algorithm.
* arscan.c (ar_scan): Verify member name length before reading.
* read.c (readline): Cast pointer arithmetic to avoid warnings.
* remake.c (update_file): Remove unreachable code.
(name_mtime): Verify symlink name length.
Create an internal type "floc" and convert all users to that type.
* gnumake.h (gmk_floc): Remove the offset field from this type.
* loadapi.c (gmk_eval): Convert gmk_floc to internal floc.
Move function prototypes into header files and out of .c files.
Use void argument lists for functions that accept no args.
Remove unused macros. Make private functions static. Align
types with printf format characters.
While displaying line numbers, show the relevant line number inside
the recipe not just the first line of the entire recipe.
Sample changes suggested by Brian Vandenberg <phantall@gmail.com>
* gnumake.h (gmk_floc): Add an 'offset' to track the recipe offset.
* read.c (eval, eval_makefile, eval_buffer): Initialize 'offset'.
(record_files, install_pattern_rule): Ditto.
* job.c (new_job, job_next_command): Update 'offset' based on the
line of the recipe we're expanding or invoking.
(child_error): Add 'offset' when showing the line number.
* function.c (func_shell_base): Ditto.
* output.c (error, fatal): Ditto.
* NEWS: Mention the new ability.
* tests/scripts/features/errors: Check the line number on errors.
* tests/scripts/functions/warning: Check the line number on warnings.
* tests/scripts/features/output-sync,
tests/scripts/features/parallelism, tests/scripts/functions/shell,
tests/scripts/functions/error: Update line numbers.
* Makefile.am, configure.ac: Check for pselect() and sys/select.h.
* main.c (main): Block SIGCHLD if we have pselect() support.
* posixos.c (jobserver_acquire): If we support pselect() then use
it to query the jobserver pipe, while also listening for SIGCHLD.
Also pselect() supports a timeout so avoid alarm() calls.
This cannot be a perfect solution because there are always other
possible places EINTR can happen, including external libraries
such as gettext, Guile etc.
* commands.c, function.c, hash.c, job.c, main.c, output.c:
use MAKE exit codes.
* makeint.h: encode make exit codes so that they are VMS compatible.
* job.c: check child exit code for VMS style exit codes.
* vmsjobs.c: save and return VMS style exit code.
* output.c (error, fatal, message): Take an extra argument specifying
how many bytes are used by the formatted arguments.
(get_buffer): New function that allocates the requested buffer size.
Remove msc_vsnprintf(), vfmtconcat(), and fmtconcat() as unneeded.
* makeint.h: Declare various helper macros for generating output.
* *.c: Change all error(), fatal(), message() calls to use the macros,
or pass the extra length argument directly.
output.c (vsnprintf) [_MSC_VER]: Define, instead of defining
snprintf, which isn't used. Reported by Christian Boos
<cboos@edgewall.org>.
NMakefile.template (OBJS): Add load.obj and posixfcn.obj.
($(OUTDIR)/pathstuff.obj): New dependency.
Suggested by Christian Boos <cboos@edgewall.org>.
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.
