    • Do not re-close files on EINTR · c1deed2f 
      POSIX is unclear what state a file descriptor is in after a signal is delivered in the middle of close. On Linux, the file is closed even if it returns -1 with errno=EINTR.

As such, do not use errno at all when closing files.

    • Check for negative return values from ReadFromOffset · 0c8bd82e 
      In some places, we check if the amount we read is a multiple of some amount we are interested in. However, ReadFromOffset returns -1 when it errors. Certain record sizes can cause ReadFromOffset to cause us to think that we succeeded when we did not.

It also results in confusing messages in logs.

    • Make exponential_distribution_test a bigger test (timeout small -> moderate). · 427d8f57 
      This test indicates it has a 90% chance of timing out at its current 60 second limit.

Stats over 1000 runs: max = 102.5s, min = 40.4s, avg = 71.1s, dev = 11.2s

Note that if you run this test locally from a workstation without flags, it'll take maybe 3 to 5 seconds.  However, the test is run with config of android_arm, which seems to drastically change the execution time.

    • debugging: account for differences in alternate signal stacks · f4988f5b 
      The alternate signal stack may be sufficiently beyond the esimated frame size
(100k).  If we run into the case that the frame is not in the correct direction
assume that the frames may be non-contiguous due to an alternate signal stack
layout.  In such a case, if we find that there is an alternate stack configured,
ignore the discontiuity (assuming that it is a removable point-wise
discontinuity) and continue the stack unwinding.  This permits us to capture
stack traces in more cases.

    • Merge contiguous mappings from the same file. · 4dc63bad 
      This allows symbolization to work if different parts of a binary's text are mapped differently, e.g. if they're mlock()ed or mapped onto huge pages.

    • Use ABSL_INTERNAL_HAS_SSE2 instead of __SSE2__ · 8e27a618 
      This ensures that emmintrin.h is included with clang-cl. Otherwise, errors like
this occur:
.../absl/container/internal/raw_hash_set.h(536,8): error: unknown type name '__m128i'
inline __m128i _mm_cmpgt_epi8_fixed(__m128i a, __m128i b) {

This aligns the include ifdef guards and the guards that use the provided APIs.
The includes are also reordered, so they appear after the config header which
provides the internal macro values.

    • Update GoogleTest version used by Abseil · d2c5297a 
      As part of this update, GoogleTest is now using the Abseil flags
implementation, and the flags usage_test needs to be modified to pass.

If building with bazel and --define=absl=1 to force GoogleTest to use
Abseil, a WORKSPACE dependency on the abseil branch of the RE2 project
is now required.
