some shells; export MAKELEVEL like gmake(1) does.
2. It is absurd for the environment variable to be one greater than the
make variable!?!?! To wit...
printf 'all:\n\t@echo ${.MAKE.LEVEL}; printenv .MAKE.LEVEL' | make -f -
The default retains the traditional NetBSD behavior, but the knob
can be set so that FreeBSD can retain their expected behavior.
This is a compromise to be sure.
Add a debug flag -dV to override the above, so that regardless of
the knob setting, the raw value of a variable can be easily seen.
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.
meta_oodate: if a file that was written or linked within our bailiwick,
but outside of .OBJDIR is missing, add it to missingFiles.
If we get to the end of the .meta file without seeing it [re]moved,
then consider the target out-of-date.
from the parsing goo. This will now use mmap for reading if it works and
fall back to read only for pipes and such. Step 1 of a cleanup program
proposed without objection on tech-toolchain.
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.
realpath(3). Consider: touch Makefile; mkdir make; make. This will set $MAKE
to $PWD/make so further attempts to use ${MAKE} will try to execute the
directory. This needs $ORIGIN to be fixed properly, or alternatively one
can duplicate the logic for execvp(3) and search the path for the make
executable. Not worth it. It was working just fine before!
.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.
Use .MAKE.LEVEL to track recursion.
The first instance of make will have .MAKE.LEVEL 0, which
can be handy for excluding rules which should not apply
in a sub-make.
gmake and freebsd's make have a similar mechanism, but each
uses a different variable to track it. Since we cannot be
compatible with both, we allow the makefiles to cope if they want
by handling the export of .MAKE.LEVEL+1 in Var_Set().
executable. Remove this so that different compiles can be binary
compared. rcsid's for all files are already embedded in the executable
so versions can be easily distinguished. (I didn't catch this on
previous passes because I did my builds on the same day.)
Note: there's a special rule for main.o in Makefile with a purpose I
can't actually discern -- I think it isn't needed, and I've flagged it
with a comment.
Saves having to malloc/free a fixed size structure.
Buf_Init() now takes ptr to Buffer to initialiase.
Change Buf_Destroy() to return ptr to string when not freed.
Remove large number of casts to (Byte) and (Byte *) - 'Byte' is 'char' here.
Buf_AddByte[s] guarantees that the data is 0 termininated, so never add '\0'.
Keep 'count' not 'left' and 'inPtr', code is simplier with only one update.
Fix fallou, no functional change.
