Since

build, but it was not parsed correctly by the buildsystem. Ignore it, as
it is known to Visual Studio and will be handled elsewhere.
Also only substitute filenames ending with .o when generating the
source .c filename, otherwise we would start to expect .cbj files to
generate .obj files (which are not generated by our build)...
In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)

grep: stess test PCRE v2 on invalid UTF-8 data
Since my
b65abcafc7 ("grep: use PCRE v2 for optimized fixed-string
search", 2019-07-01) we've been dying on invalid UTF-8 data when
grepping for fixed strings if the following are all true:
* The subject string is non-ASCII (e.g. "ævar")
* We're under a is_utf8_locale(), e.g. "en_US.UTF-8", not "C"
* We compiled with PCRE v2
* That PCRE v2 did not have JIT support
The last of those is why this wasn't caught earlier, per pcre2jit(3):
"unless PCRE2_NO_UTF_CHECK is set, a UTF subject string is tested
for validity. In the interests of speed, these checks do not
happen on the JIT fast path, and if invalid data is passed, the
result is undefined."
I.e. the subject being matched against our pattern was invalid, but we
were lucky and getting away with it on the JIT path, but the non-JIT
one is stricter.
This patch does nothing to fix that, instead we sneak in support for
fixed patterns starting with "(*NO_JIT)", this disables the PCRE v2
jit with implicit fixed-string matching for testing, see
pcre2syntax(3) the syntax.
This is technically a change in behavior, but it's so obscure that I
figured it was OK. We'd previously consider this an invalid regular
expression as regcomp() would die on it, now we feed it to the PCRE v2
fixed-string path. I thought this was better than introducing yet
another GIT_TEST_* environment variable.
We're also relying on a behavior of PCRE v2 that technically could
change, but I think the test coverage is worth dipping our toe into
some somewhat undefined behavior.

grep: stop using a custom JIT stack with PCRE v1
Simplify the PCRE v1 code for the same reasons as for the PCRE v2 code
in the last commit. Unlike with v2 we actually used the custom stack
in v1, but let's use PCRE's built-in 32 KB one instead, since
experience with v2 shows that's enough. Most distros are already using
v2 as a default, and the underlying sljit code is the same.
Unfortunately we can't just pass a NULL to pcre_jit_exec() as with
pcre2_jit_match(). Unlike the v2 function it doesn't support
that. Instead we need to use the fatter pcre_exec() if we'd like the
same behavior.
This will make things slightly slower than on the fast-path function,
but it's OK since we care less about v1 performance these days since
we have and recommend v2. Running a similar performance test as what I
ran in
fbaceaac47 ("grep: add support for the PCRE v1 JIT API",
2017-05-25) via:
GIT_PERF_REPEAT_COUNT=30 GIT_PERF_LARGE_REPO=~/g/linux GIT_PERF_MAKE_OPTS='-j8 USE_LIBPCRE1=Y CFLAGS=-O3 LIBPCREDIR=/home/avar/g/pcre/inst' ./run HEAD~ HEAD p7820-grep-engines.sh
Gives us this, just the /perl/ results:

It will also implicitly re-enable UTF-8 validation for PCRE v1. As
noted in [1] we now have cases as a result where PCRE v1 is more eager
to error out. Subsequent patches will fix that for v2, and I think
it's fair to tell v1 users "just upgrade" and not worry about that
edge case for v1.

grep: stop "using" a custom JIT stack with PCRE v2
As reported in [1] the code I added in
94da9193a6 ("grep: add support
for PCRE v2", 2017-06-01) to use a custom JIT stack has never
worked. It was incorrectly copy/pasted from code I added in
fbaceaac47 ("grep: add support for the PCRE v1 JIT API", 2017-05-25),
which did work.
Thus our intention of starting with 1 byte of stack at a maximum of 1
MB didn't happen, we'd always use the 32 KB stack provided by PCRE
v2's jit_machine_stack_exec()[2]. The reason I allocated a custom
stack at all was this advice in pcrejit(3) (same in pcre2jit(3)):
"By default, it uses 32KiB on the machine stack. However, some
large or complicated patterns need more than this"
Since we've haven't had any reports of users running into
PCRE2_ERROR_JIT_STACKLIMIT in the wild I think we can safely assume
that we can just use the library defaults instead and drop this
code. This won't change with the wider use of PCRE v2 in
ed0479ce3d ("Merge branch 'ab/no-kwset' into next", 2019-07-15), a
fixed string search is not a "large or complicated pattern".
For good measure I ran the performance test noted in
94da9193a6,
although the command is simpler now due to my
0f50c8e32c ("Makefile:
remove the NO_R_TO_GCC_LINKER flag", 2019-05-17):
GIT_PERF_REPEAT_COUNT=30 GIT_PERF_LARGE_REPO=~/g/linux GIT_PERF_MAKE_OPTS='-j8 USE_LIBPCRE2=Y CFLAGS=-O3 LIBPCREDIR=/home/avar/g/pcre2/inst' ./run HEAD~ HEAD p7820-grep-engines.sh
Just the /perl/ results are:
Test HEAD~ HEAD
---------------------------------------------------------------------------------------
7820.3: perl grep 'how.to' 0.17(0.27+0.65) 0.17(0.24+0.68) +0.0%
7820.7: perl grep '^how to' 0.16(0.23+0.66) 0.16(0.23+0.67) +0.0%
7820.11: perl grep '[how] to' 0.18(0.35+0.62) 0.18(0.33+0.65) +0.0%

So, as expected there's no change, and running with valgrind reveals
that we have fewer allocations now.
As noted in [3] there are known regexes that will fail with the lower
stack limit, the way GNU grep fixed it is interesting, although I
believe the implementation is overly verbose, they could make PCRE v2
handle that gradual re-allocation, that's what min/max memory is
for.
So we might end up bringing this back, I'm more inclined to just kick
such cases upstairs to PCRE maintainers as a bug, perhaps they'll add
some overall "just allocate more then" flag to make this easier. In
any case there's no functional change here, we didn't have a custom
stack, so let's apply this first, we can always revert it later.
1. https://public-inbox.org/git/
20190721194052.15440-1-carenas@gmail.com/
2. I didn't really intend to start with 1 byte, looking at the PCRE v2
code again what happened is that I cargo-culted some of PCRE v2's
own test code which was meant to test re-allocations. It's more
sane to start with say 32 KB with a max of 1 MB, as pcre2grep.c
does.
