607628d349 Support ZSTD with finalized format
Summary:
ZSTD 1.0.0 is coming. We can finally add a support of ZSTD without worrying about compatibility.
Still keep ZSTDNotFinal for compatibility reason.

Test Plan: Run all tests. Run db_bench with ZSTD version with RocksDB built with ZSTD 1.0 and older.

9c8ac144bd Avoid duplicate task creation for RocksDB contruns
Summary: We rely on a basic evaluation logic: when using an expression `A || B`, the `B` part will only get evaluated when `A` fails. Therefore the task creation tool is guaranteed to run if previous build/test step failed. To indicate the correct return value to shell, the task creation tool will call `exit(1)` which will cause Sandcastle to mark it as a failure.

Test Plan:
- Land the changes.
- Trigger a RocksDB contrun - observe the results.
- Look at the results from the nightly runs and fix issues as necessary.

Current testing so far has been in isolation for various components.

a52e4d7d02 Framework for enabling continuous RocksDB build and tests
Summary:
The main PHP code churn is caused by extracting the common code from `FacebookArcanistConfiguration.php` and `FacebookOldArcanistConfiguration.php` into `RocksDBCommonDeterminator.php`. This is necessary both for reducing the duplication of code and making sure that we can execute the common core logic separately from continuous runs.

The main logic in `RocksDBCommonDeterminator.php` remains quite the same with the exception of some things:

- Adding separation between the cases when a diff is submitted //vs.// when the code is triggered from a continuous run. There are certain actions which we should do in a case of diff only.

- Adding reporting - now the person who authored the diff will receive e-mail notifications if any of the jobs have failed.

- Enabling assertions and making sure that we'll terminate on failure. This is an internal code used by competent engineers, so instead of `if (!condition) { echo "Something"; exit(1); }` for every invariant I think that `assert(condition)` provides better readability with the same behavior. Especially taking into account that we're talking about things which shouldn't ever happen.

Enabling this entire process will be triggered internally and will be a subject of a separate code review. We should discuss the details of triggering continuous RocksDB build and tests on that diff.

Test Plan:
- Make sure that `[p]arc diff` scenario isn't broken by verifying that tests validating this diff will pass.
- Private testing of triggering the continuous build script.
- Once the changes will land then author an internal job which will use the script and verify its validity.

    --num=10000000` end verified that jemalloc dump is present in LOG file.
    2) Build rocksdb using `DISABLE_JEMALLOC=1  make db_bench -j32` and ran
    the same db_bench tool and found the following message in LOG file:
    "Please compile with jemalloc to enable malloc dump".
    3) Also built rocksdb using `make` command on MacOS to verify behavior
    in non-FB environment.
    Also to debug build configuration change temporary changed
    AM_DEFAULT_VERBOSITY = 1 in Makefile to see compiler and build
    tools output. For case 1) -DROCKSDB_JEMALLOC was present in compiler
    command line. For both 2) and 3) this flag was not present.

b71c4e613f Alpine Linux Build (#990)
* Musl libc does not provide adaptive mutex. Added feature test for PTHREAD_MUTEX_ADAPTIVE_NP.

* Musl libc does not provide backtrace(3). Added a feature check for backtrace(3).

* Fixed compiler error.

* Musl libc does not implement backtrace(3). Added platform check for libexecinfo.

* Alpine does not appear to support gcc -pg option. By default (gcc has PIE option enabled) it fails with:

gcc: error: -pie and -pg|p|profile are incompatible when linking

When -fno-PIE and -nopie are used it fails with:

/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/../../../../x86_64-alpine-linux-musl/bin/ld: cannot find gcrt1.o: No such file or directory

Added gcc -pg platform test and output PROFILING_FLAGS accordingly. Replaced pg var in Makefile with PROFILING_FLAGS.

* fix segfault when TEST_IOCTL_FRIENDLY_TMPDIR is undefined and default candidates are not suitable

* use ASSERT_DOUBLE_EQ instead of ASSERT_EQ

* When compiled with ROCKSDB_MALLOC_USABLE_SIZE UniversalCompactionFourPaths and UniversalCompactionSecondPathRatio tests fail due to premature memtable flushes on systems with 16-byte alignment. Arena runs out of block space before GenerateNewFile() completes.

Increased options.write_buffer_size.

ec84bef24a New legocastle output parsing
Summary:
Added a python script to parse combined stdout/stderr of legocastle
steps. Previously we just matched words like 'Failure', which didn't work since
even our test names matched that pattern.

I went through all the legocastle steps to come up with strict failure regexes
for the common failure cases. There is also some more complex logic to present
gtest failures, since the test name and failure message are not on the same
line.

There will definitely be error cases that don't match any of these patterns, so
we can iterate on it over time.

Test Plan:
no end-to-end test. I ran the legocastle steps locally and piped to
my script, then verified output, e.g.,

  $ set -o pipefail && TEST_TMPDIR=/dev/shm/rocksdb COMPILE_WITH_ASAN=1 OPT=-g make J=1 asan_check |& /usr/facebook/ops/scripts/asan_symbolize.py -d |& python build_tools/error_filter.py asan

Summary:
Undefined Behavior Sanitizer (ubsan) is //a good thing// which will help us to find sneaky bugs with low cost. Please see http://developerblog.redhat.com/2014/10/16/gcc-undefined-behavior-sanitizer-ubsan/ for more details and official GCC documentation for more context: https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html.

Changes itself are quite simple and pretty much imitating whatever is implemented for ASan.

Hooking the UBsan validation build to Sandcastle is a separate step and will be dealt as separate diff because code is in internal repository.

Test Plan: Make sure that that there no regressions when it comes to builds and test pass rate.

6a2b4fcb80 Add flag to forcibly disable fallocate
Summary:
see https://github.com/facebook/rocksdb/issues/977; there are issues
with fallocate() on certain filesystems/kernel versions that can lead it to pre-
allocating blocks but never freeing them, even if they're unused.

Test Plan:
verified build commands omit DROCKSDB_FALLOCATE_PRESENT when this env
variable is set.

without disabling it:

  $ ROCKSDB_NO_FBCODE=1 make -n env_test | grep -q DROCKSDB_FALLOCATE_PRESENT ; echo $?
  0

with disabling it:

  $ ROCKSDB_NO_FBCODE=1 DISABLE_FALLOCATE=1 make -n env_test | grep -q DROCKSDB_FALLOCATE_PRESENT ; echo $?
  1
