- poll can return EINTR, it is not restartable like read/write
- check poll return
- it does not make sense to check readyfd() is nready < 0
- check read return
- always call Job_CatchChildren, it is harmless
- short circuit scanning of the poll array if we got all the ready descriptors
with versions prefixed by MAKE_ATTR_* to avoid modifying the
implementation namespace. Make sure they are available in all places
using nonints.h to fix bootstrap on Linux.
recheck when needed. Before it used to be the case that we could only
use the cached entry once. Once the cached entry was used, we removed
it from the cache. Now it is kept forever.
These capture all the interesting data - useful for debugging.
In such cases there is no need to replicate commands in the build log.
Rather than run the entire build .SILENT, allow meta mode to set that flag
per target iff a .meta file is created.
Normal behavior is retained for targets where no .meta file is created,
ensuring that no build data is lost.
In this mode, a .meta file is created for each target, capturing
the expanded commands used, any command output, and if filemon(9)
is available, a record of system calls which are of interest.
Not enabled unless USE_META=yes is set when building make.
Also, if FILEMON_H exists, meta.c will be compiled to use filemon(9).
If we encounter an error and run the .ERROR target, we may
reap a pid which jobs is waiting for. Ensure that we
cleanup so that make isn't left waiting for an already
deceased child.
As the comment says in JobPrintJob set JOB_IGNERR with - commands. Fix
whitespace so that the output is consistent, although there are two separate
execution logic implementations (command.c, job.c)
.error "message"
.warning "message"
based on FreeBSD implementation.
add .info while were at it.
.ERROR: a target to run on error.
We pass the failing GNode to PrintOnError so it can set
.ERROR_TARGET.
.MAKE.MAKEFILE_PREFERENCE
As a means to control make's list of prefered makefile names.
(Default: "makefile Makefile")
.MAKE.DEPENDFILE
Names the file to read dependencies from
(Default ".depend")
.MAKE.MODE
Processed after all makefiles are read.
Can put make into "compat" mode (more to come).
Fix:
compat.c: Error code should not be sent to debug_file.
Make_DoAllVar: use DONE_ALLSRC to avoid processing a node multiple times.
ReadMakefile: we can simply use doing_depend to control setting MAKEFILE.
to avoid seg-fault. Also the NULL filename will cause ParseVErrorInternal
to skip trying to report file and line number info.
If CondToken is called outside the context of a .if etc, variables in
the expression being parsed will already be expanded, so allow for
an unqouted number to jump us back into the compare logic.
This allows ${${SomeNumber:U42} > 0:?True:False} to work anywhere.
Job_Finish should process postCommands if it has commands or children.
bmake_malloc and friends. Implement them via macros for the native case
and provide fallback implementations otherwise. Avoid polluting the
namespace by not defining enomem globally. Don't bother to provide
strdup and strndup, they were only used for the estrdup and estrndup
comapt code.
This addresses the presence of emalloc in system libraries on A/UX and
resulted strange issues as reported by Timothy E. Larson.
to override the default shell:
* Rename _BASENAME_DEFSHELL to DEFSHELL_CUSTOM, because it's no longer
always a basename, it might be a full path;
* Rename DEFSHELL to DEFSHELL_INDEX, because it's actually an index into
an array;
* Provide symbolic names for the possible values if DEFSHELL_INDEX;
* Document how the build environment may set DEFSHELL_INDEX or
DEFSHELL_CUSTOM to choose the default shell;
* Move the fallback definition of DEFSHELL_INDEX from config.h to job.c,
because it's used only in job.c.
Discussed with sjg.
