Subject: [PATCH 3/5] cocci: make "coccicheck" rule incremental
Date: Thu, 25 Aug 2022 16:36:15 +0200 [thread overview]
Message-ID: <patch-3.5-6fa83695f1f-20220825T141212Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-0.5-00000000000-20220825T141212Z-avarab@gmail.com>
Optimize the very slow "coccicheck" target to take advantage of
incremental rebuilding, and fix outstanding bugs and dependency
problems with the existing rule.
The rule is now faster both on the initial run as we can make better
use of GNU make's parallelism than the old ad-hoc combination of
make's parallelism combined with $(SPATCH_BATCH_SIZE) and "xargs -n".
It also makes us *much* faster when incrementally building, it's now
viable to "make coccicheck" as topic branches are merged down.
The rule didn't use FORCE (or its equivalents) before, so a:
make coccicheck
make coccicheck
Would report nothing to do on the second iteration. But all of our
patch output depended on all $(COCCI_SOURCES) files, therefore e.g.:
make -W grep.c coccicheck
Would be the same as doing a full re-run. A change in a single file
would force us to do a full re-run.
The reason for this (not the initial rationale, but my analysis) is:
* Since we create a single "*.cocci.patch+" we don't know where to
pick up where we left off. Note that (per [1]) we've had a race
condition since 960154b9c17 (coccicheck: optionally batch spatch
invocations, 2019-05-06) which might result in us producing corrupt
patches to to the concurrent appending to "$@+" in the pre-image.
That bug is now fixed.
* We've been carrying forward the dependency on the *.c files since
63f0a758a06 (add coccicheck make target, 2016-09-15) the rule was
initially added as a sort of poor man's dependency discovery.
As we don't include other *.c files depending on other *.c files
has always been broken, as could be trivially demonstrated
e.g. with:
make coccicheck
make -W strbuf.h coccicheck
However, depending on the corresponding *.c files has been doing
something, namely that *if* an API change modified both *.c and *.h
files we'd catch the change to the *.h we care about via the *.c
being changed.
For API changes that happened only via *.h files we'd do the wrong
thing before this change, but e.g. for function additions (not
"static inline" ones) catch the *.h change by proxy.
Now we'll instead:
* Create a <RULE>/<FILE> pair in the .build directory, E.g. for
swap.cocci and grep.c we'll create
.build/contrib/coccinelle/swap.cocci.patch/grep.c.
That file is the diff we'll apply for that <RULE>-<FILE>
combination, if there's no changes to me made (the common case)
it'll be an empty file.
* Our generated *.patch
file (e.g. contrib/coccinelle/swap.cocci.patch) is now a simple "cat
$^" of all of all of the <RULE>/<FILE> files for a given <RULE>.
See 1cc0425a27c (Makefile: have "make pot" not "reset --hard",
2022-05-26) for another recent rule that used that technique.
* We depend on a .build/<RULE>.ok file, which in turn depends on our
<RULE>. This emulates the previous "test -s" test, but in a more
Makefile-native way (e.g. -k works as expected).
As noted above this change fixes existing dependency issues,
e.g. changing strbuf.h will now trigger a re-build. Our default is to
depend on $(FOUND_H_SOURCES). This makes incremental re-building
possible, but it's still fairly slow, as modifying one header will
cause a full re-build of everything.
Which is why we'll not depend on $(FOUND_H_SOURCES) but the *.o file
corresponding to the *.c file, if it exists already. This means that
we can do:
make all
make coccicheck
make -W column.h coccicheck
By depending on the *.o we piggy-back on
COMPUTE_HEADER_DEPENDENCIES. See c234e8a0ecf (Makefile: make the
"sparse" target non-.PHONY, 2021-09-23) for prior art of doing that
for the *.sp files. E.g.:
make contrib/coccinelle/free.cocci.patch
make -W column.h contrib/coccinelle/free.cocci.patch
Will take around 15 seconds for the second command on my 8 core box if
I didn't run "make" beforehand to create the *.o files. But around 2
seconds if I did and we have those "*.o" files.
Notes about the approach of piggy-backing on *.o for dependencies:
* It *is* a trade-off since we'll pay the extra cost of running the C
compiler, but we're probably doing that anyway. The compiler is much
faster than "spatch", so even though we need to re-compile the *.o to
create the dependency info for the *.c for "spatch" it's
faster (especially if using "ccache").
* If that *.o file doesn't exist we'll depend on an intermediate file
of ours which in turn depends on $(FOUND_H_SOURCES).
This covers both an initial build, or where "coccicheck" is run
without running "all" beforehand, and because we run "coccicheck"
on e.g. files in compat/* that we don't know how to build unless
the requisite flag was provided to the Makefile.
Most of the runtime of "incremental" runs is now spent on various
compat/* files, i.e. we conditionally add files to COMPAT_OBJS, and
therefore conflate whether we *can* compile an object and generate
dependency information for it with whether we'd like to link it
into our binary.
Before this change the distinction didn't matter, but now one way
to make this even faster on incremental builds would be to peel
those concerns apart so that we can see that e.g. compat/mmap.c
doesn't depend on column.h.
Further implementation details & notes:
* We can take better advantage of parallelism, while making sure that
we don't racily append to the contrib/coccinelle/swap.cocci.patch
file from multiple workers.
Before this change running "make coccicheck" would by default end
up pegging just one CPU at the very end for a while, usually as
we'd finish whichever *.cocci rule was the most expensive.
This could be mitigated by combining "make -jN" with
SPATCH_BATCH_SIZE, see 960154b9c17 (coccicheck: optionally batch
spatch invocations, 2019-05-06). But doing so required careful
juggling, as e.g. setting both to 4 would yield 16 workers.
There will be cases where getting rid of "SPATCH_BATCH_SIZE" makes
things worse, but a from-scratch "make coccicheck" with the default
of SPATCH_BATCH_SIZE=1 (and tweaking it doesn't make a difference)
is faster (~3m36s v.s. ~3m56s) with this approach, as we can feed
the CPU more work in a less staggered way.
* Getting rid of "SPATCH_BATCH_SIZE" particularly helps in cases
where the default of 1 yields parallelism under "make coccicheck",
but then running e.g.:
make -W contrib/coccinelle/swap.cocci coccicheck
I.e. before that would use only one CPU core, until the user
remembered to adjust "SPATCH_BATCH_SIZE" differently than the
setting that makes sense when doing a non-incremental run of "make
coccicheck".
* The change here to
"contrib/coccinelle/the_repository.pending.cocci" is because we've
been spewing out this warning into our $@.log since that rule was
added:
warning: rule starting on line 21: metavariable F not used in the - or context code
It's being fixed here because we'll now notice on "make
coccicheck-pending", since we're not redirecting all of STDERR to a
log file, instead we use the "--very-quiet" option.
Outstanding issues & future work:
* We could get rid of "--all-includes" in favor of manually
specifying a list of includes to give to "spatch(1)".
As noted upthread of [2] a naïve removal of "--all-includes" will
result in broken *.cocci patches, but if we know the exhaustive
list of includes via COMPUTE_HEADER_DEPENDENCIES we don't need to
re-scan for them, we could grab the headers to include from the
.depend.d/<file>.o.d and supply them with the "--include" option to
spatch(1).q
* We can generalize COMPUTE_HEADER_DEPENDENCIES to spew out the list
of *.h dependencies without making a *.o object, which is slightly
faster, and would also benefit the "make sparse" target. We'd still
need to run the compiler, it would just have less work to do.
