This makes it possible to use expressions like
${("${LIST:Msomething"}):?present:absent}
it also makes treatment of lhs and rhs more consistent, and
makes CondToken easier to read.
Update unit-test/cond1 to test new features.
No functional change under NetBSD.
Restarting a getopt(3) loop is an extension to the posix getopt(3)
behavior and is not portable.
Fixes tools build (tools/groff) under Cygwin.
- new dir.c function: Dir_FindHereOrAbove:
Search for a path in the current directory and then all the directories
above it in turn until the path is found or we reach the root ("/").
- add hooks to use it in main.c for -m and syspath (compiled in
_PATH_DEFSYSPATH and $MAKESYSPATH).
- updated man page
Improve description of variable modifiers.
In the variable list, be more specific referring to "environment variables"
rather than just relying upon the formatting difference between .Ev and .Va.
Using -e in sh/ksh to stop on error doesn't work with grouped commands. At
least for any SUSE compliant sh(1). Instead, extend the Shell struct and add
errOut which provides a template to use to check error status from commands.
objdir) try opening the file from curdir and if that fails try from objdir.
This way .depend files get picked up via their full path names rather than
just .depend so vars like PARSEDIR, PARSEFILE are then set correctly. This
fixes PR#13289 reporting incorrect pathnames for .depends with errors in
them
In the "modifier description" list, show each modifier with the leading `:'.
Rationale: it's hard to search for modifiers without it, and we already do
the same thing in the -options and .makecommands lists. I now find it much
easier to find the description for a modifier in the man page.
* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).
Also :tW and a W flag to :C and :S to allow treating value as a single word.
Add unit tests for the above, and fix some corner cases.
Based on patches supplied by Alan Barrett <apb@cequrux.com>
the first two directory entries are "." and "..".
This behaviour is not required by applicable standards, and
actually not provided by "coda".
Now we get the "." and ".." into the per-directiry hash tables,
but this should not hurt.
printf "all:\n\ttrue\n\t@false\n" | make -f -
the error output now looks like:
*** Failed target: all
*** Failed command: false
*** Error code 1
instead of just
*** Error code 1
XXX: add this support for make -j builds.
make it depend only on the expansion of src that matches.
Otherwise given:
a b c: ${.TARGET}.x
a b and c will each depend on a.x, b.x and c.x
Further, we only _need_ to do ParseDoSpecialSrc if a .WAIT appears
in the source list - so establish that up front.
executed the make job with sigprocmask(SIG_BLOCK) in effect for a
number of signals including SIGCHLD. This caused recursive submakes
of the make process in question not to receive SIGCHLDs when their
jobs exited. This was a second, independent cause of bin/18895 in
addition to the race condition already fixed. Fixed by unblocking all
signals before executing the job.
search list that will be used. Thus 'dot' and 'cur' will appear in
${.PATH} either at the start or end depending on .DOTLAST even though
they are not strictly in dirSearchPath.
When .CURDIR is assigned to - re-set the 'cur' Path.
Finally, when checking subdirs, look in 'dot' and 'cur' (first or last
depending on .DOTLAST) just as we do in other situations.
seconds if a SIGCHLD arrived while make was not blocked in poll(),
by making the SIGCHLD handler write to a pipe included in the poll.
Avoided the need to implement a duplicate fix for the USE_SELECT case
by emulating poll() in terms of select() when USE_SELECT is defined.
Fixes bin/18895.
- consistently support __hpux (which the HP compilers define) as well
as __hpux__ (not sure which compilers set this, but retained anyway)
- fix a typo in the definition of signal(). arguably the codebase should
just be converted to sigaction()...
In these revisions `::' dependency handling was simplified by not linking
the cohort nodes into the dependency graph. This broke dependency checking
on all but the first instance of a `::' target since all of the cohort nodes
now just form a collection of disconnected dependency graphs.
Fix this by keeping a back-reference in each cohort to its leader (the
first instance of a :: node with the same name) and a count of the number
of cohorts that need to be made before dependent nodes are scheduled.
Classically, we'd need six centurions for cohort, but in this case one
suffices...
while setting up a child process. This prevents the major sources of
list inconsistencies that may result from doing list manipulations
from a signal handler.
XXX - all Lst_*() operations are at risk; look for ways to avoid touching
so much global state from the signal handlers.
- don't block the signal we're about to send to ourselves to
take the default action for
- restore the signal handler for the current signal
- remove duplicate sigprocmask() call
As a result, restoring the SIGTSTP handler in JobContinueSig() is no longer
necessary.
1. Compensate for h-pox assert brain damage where it gets confused by the
string in: assert(!memcmp(foo, "in", 2)); I miss the h-pox broken compiler,
I had not had to work around it for years.
2. Oh, finally h-pox has random() and utimes(). We don't need our own anymore.
the removal of .USE nodes from a node's children list in case a given .USE
nodes appears multiple times on that list, preventing the target from ever
making it on the `to be made' queue.
Since the suffix rule processing code deals itself with removing the
transformation nodes from the parents to which it applies them, arrange
for doing the same for .USE nodes in MakeHandleUse() instead of in
Make_HandleUse(), and still use the OP_MARK stuff to avoid duplication
of commands.
Also, since Make_HandleUse() is not a list callback function and its
return value is no longer used, make its return type void.
normal target (the latter dependency being the reason why it's made),
the .MADE parent should not be put on the `toBeMade' list again (in
Make_Update()) since it was already put on it in Make_ExpandUse().
Doing so would cause the rules for the .MADE target to be executed
(at least) twice, and also mess up the unmade children count of _its_
parent, resulting in spurious graph cylce detection.
To achieve this, make sure the unmade children count of the .MADE target
is set to zero before enqueueing it on the `toBeMade' list in
Make_ExpandUse(). Then, in Make_Update(), check if the parent has the
.MADE attribute before diddling with the queue.
For the same reason the status of a node must not be set to UPTODATE
unconditionally in compat mode, since that will prevent the node from
being built even if it is the source of a normal target. Instead,
check both its state and the type of the parent to decide whether to
continue on behalf of the current parent.
* There is no -indent option to .Bd or .Bl, although you would
never know that from its frequent use in this tree. There is a
"-offset indent" combination that makes sense, and you can certainly
say "-width indent".
* Also, you can't markup the -width option argument, tho you CAN
use a callable macro. So "-width Ar filename" doesn't make sense,
but either "-width Ar" or "-width filename" does, as might something
like "-width xxfilename" for a little extra space.
* There are a lot of needlessly complex hanging tag macros in man4 used
to create simple item lists. Those should be simplified one of these
days before someone copies and edits yet another man4 page.
