7 years agogrep: stess test PCRE v2 on invalid UTF-8 data

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.

7 years agogrep: stop using a custom JIT stack with PCRE v1
Ævar Arnfjörð Bjarmason [Fri, 26 Jul 2019 15:08:13 +0000 (17:08 +0200)]
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.

7 years agogrep: stop "using" a custom JIT stack with PCRE v2
Ævar Arnfjörð Bjarmason [Fri, 26 Jul 2019 15:08:12 +0000 (17:08 +0200)]
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:

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.

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.

7 years agogrep: remove overly paranoid BUG(...) code
Ævar Arnfjörð Bjarmason [Fri, 26 Jul 2019 15:08:11 +0000 (17:08 +0200)]
grep: remove overly paranoid BUG(...) code

Remove code that would trigger if pcre_config() or pcre2_config() was
so broken that "do we have JIT?" wouldn't return a boolean.

I added this code back in fbaceaac47 ("grep: add support for the PCRE
v1 JIT API", 2017-05-25) and then as noted in f002532784 ("grep: print
the pcre2_jit_on value", 2019-07-22) incorrectly copy/pasted some of
it in 94da9193a6 ("grep: add support for PCRE v2", 2017-06-01).

Let's just remove this code. Being this paranoid about the
pcre2?_config() function itself being broken is crossing the line into
unreasonable paranoia.

xdiff: clamp function context indices in post-image

After finding a function line for --function-context in the pre-image,
xdl_emit_diff() calculates the equivalent line in the post-image.  It
assumes that the lines between changes are the same on both sides.  If
the option --ignore-blank-lines was also given then this is not
necessarily true.

Clamp the calculation results for start and end of the function context
to prevent out-of-bounds array accesses.

Note that this _just_ fixes the case where our mismatch sends us off the
beginning of the file. There are likely other cases where our assumption
causes us to go to the wrong line within the file. Nobody has developed
a test case yet, and the ultimate fix is likely more complicated than
this patch. But this at least prevents a segfault in the meantime.

7 years agotravis-ci: build with GCC 4.8 as well
SZEDER Gábor [Thu, 18 Jul 2019 15:22:34 +0000 (17:22 +0200)]
travis-ci: build with GCC 4.8 as well

C99 'for' loop initial declaration, i.e. 'for (int i = 0; i < n; i++)',
is not allowed in Git's codebase yet, to maintain compatibility with
some older compilers.

Our Travis CI builds used to catch 'for' loop initial declarations,
because the GETTEXT_POISON job has always built Git with the default
'cc', which in Travis CI's previous default Linux image (based on
Ubuntu 14.04 Trusty) is GCC 4.8, and that GCC version errors out on
this construct (not only with DEVELOPER=1, but with our default CFLAGS
as well).  Alas, that's not the case anymore, becase after 14.04's EOL
Travis CI's current default Linux image is based on Ubuntu 16.04
Xenial [1] and its default 'cc' is now GCC 5.4, which, just like all
later GCC and Clang versions, simply accepts this construct, even if
we don't explicitly specify '-std=c99'.

Ideally we would adjust our CFLAGS used with DEVELOPER=1 to catch this
undesired construct already when contributors build Git on their own
machines.  Unfortunately, however, there seems to be no compiler
option that would catch only this particular construct without choking
on many other things, e.g. while a later compiler with '-std=c90'
and/or '-ansi' does catch this construct, it can't build Git because
of several screenfulls of other errors.

Add the 'linux-gcc-4.8' job to Travis CI, in order to build Git with
GCC 4.8, and thus to timely catch any 'for' loop initial declarations.
To catch those it's sufficient to only build Git with GCC 4.8, so
don't run the test suite in this job, because 'make test' takes rather
long [2], and it's already run five times in other jobs, so we
wouldn't get our time's worth.

[1] The Azure Pipelines builds have been using Ubuntu 16.04 images
    from the start, so I belive they never caught 'for' loop initial
    declarations.

[2] On Travis CI 'make test' alone would take about 9 minutes in this
    new job (without running httpd, Subversion, and P4 tests).  For
    comparison, starting the job and building Git with GCC 4.8 takes
    only about 2 minutes.
