1ba92b8582 Only search specific directories in Python check (#6225)
Summary:
The new Python syntax check could fail if external entities
were cloned or symlinked to a subdir in a rocksdb git clone. (E.g.
Facebook internal LITE build.) Only look for Python files in specific
subdirs
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6225

Test Plan: python tools/check_all_python.py (still 34 files checked)

9ff569bdfc Temporarily disable level_compaction_dynamic_level_bytes in crash test (#6217)
Summary:
We're seeing assertion violations like this in crash test:

db_stress: table/block_based/block_based_table_reader.cc:4129: virtual uint64_t rocksdb::BlockBasedTable::ApproximateSize(const rocksdb::Slice&, const rocksdb::Slice&, rocksdb::TableReaderCaller): Assertion `end_offset >= start_offset' failed.***

And ApproximateSize appears only to be called with the level_compaction_dynamic_level_bytes option.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6217

Test Plan:
temporarily put an assert(false) in ApproximateSize and
briefly run 'make crash_test'

130e710056 Add BlobDB GC cutoff parameter to db_bench (#6211)
Summary:
The patch makes it possible to set the BlobDB configuration option
`garbage_collection_cutoff` on the command line. In addition, it changes
the `db_bench` code so that the default values of BlobDB related
parameters are taken from the defaults of the actual BlobDB
configuration options (note: this changes the the default of
`blob_db_bytes_per_sync`).
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6211

Test Plan: Ran `db_bench` with various values of the new parameter.

9f250dd88e crash_test: two fixes (#6200)
Summary:
Fix two crash test issues:
1. sync mode should not run with disable_wal=true
2. disable "compaction_readahead_size" for now. With it on, some block checksum verification failure will happen in compaction paths. Not sure why, but disable it for now to keep the test clean.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6200

Test Plan: Run "make crash_test" and "make crash_test_with_atomic_flush" and see it runs way longer than before the fix without failing.

afa2420c2b Introduce a new storage specific Env API (#5761)
Summary:
The current Env API encompasses both storage/file operations, as well as OS related operations. Most of the APIs return a Status, which does not have enough metadata about an error, such as whether its retry-able or not, scope (i.e fault domain) of the error etc., that may be required in order to properly handle a storage error. The file APIs also do not provide enough control over the IO SLA, such as timeout, prioritization, hinting about placement and redundancy etc.

This PR separates out the file/storage APIs from Env into a new FileSystem class. The APIs are updated to return an IOStatus with metadata about the error, as well as to take an IOOptions structure as input in order to allow more control over the IO.

The user can set both ```options.env``` and ```options.file_system``` to specify that RocksDB should use the former for OS related operations and the latter for storage operations. Internally, a ```CompositeEnvWrapper``` has been introduced that inherits from ```Env``` and redirects individual methods to either an ```Env``` implementation or the ```FileSystem``` as appropriate. When options are sanitized during ```DB::Open```, ```options.env``` is replaced with a newly allocated ```CompositeEnvWrapper``` instance if both env and file_system have been specified. This way, the rest of the RocksDB code can continue to function as before.

This PR also ports PosixEnv to the new API by splitting it into two - PosixEnv and PosixFileSystem. PosixEnv is defined as a sub-class of CompositeEnvWrapper, and threading/time functions are overridden with Posix specific implementations in order to avoid an extra level of indirection.

The ```CompositeEnvWrapper``` translates ```IOStatus``` return code to ```Status```, and sets the severity to ```kSoftError``` if the io_status is retryable. The error handling code in RocksDB can then recover the DB automatically.

6380df5e10 Vary bloom_bits in db_crashtest (#6103)
Summary:
Especially with non-integral bits/key now supported,
db_crashtest should vary the bloom_bits configuration. The probabilities
look like this:

1/2 chance of a uniform int from 0 to 19. This includes overall 1/40
chance of 0 which disables the bloom filter.

1/2 chance of a float from a lognormal distribution with a median of 10.
This always produces positive values but with a decent chance of < 1
(overall ~1/40) or > 100 (overall ~1/40), the enforced/coerced
implementation limits.

7d79b32618 Break db_stress_tool.cc to a list of source files (#6134)
Summary:
db_stress_tool.cc now is a giant file. In order to main it easier to improve and maintain, break it down to multiple source files.
Most classes are turned into their own files. Separate .h and .cc files are created for gflag definiations. Another .h and .cc files are created for some common functions. Some test execution logic that is only loosely related to class StressTest is moved to db_stress_driver.h and db_stress_driver.cc. All the files are located under db_stress_tool/. The directory name is created as such because if we end it with either stress or test, .gitignore will ignore any file under it and makes it prone to issues in developements.

100b5e69f3 Fix build failure for db_stress tool when building with CMake (#6117)
Summary:
PR https://github.com/facebook/rocksdb/issues/5937 changed the db_stress tool to also require db_stress_tool.cc,
and updated the Makefile but not the CMakeLists.txt file.  This updates
the CMakeLists.txt file so that the CMake build succeeds again.

PR https://github.com/facebook/rocksdb/issues/5950 updated the Makefile build to package db_stress_tool.cc into
its own librocksdb_stress.a library.  I haven't done that here since
there didn't really seem to be much benefit: the Makefile-based build
does not install this library.

4e0dcd36df db_stress sometimes generates keys close to SST file boundaries (#6037)
Summary:
Recently, a bug was found related to a seek key that is close to SST file boundary. However, it only occurs in a very small chance in db_stress, because the chance that a random key hits SST file boundaries is small. To boost the chance, with 1/16 chance, we pick keys that are close to SST file boundaries.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6037

Test Plan: Did some manual printing out, and hack to cover the key generation logic to be correct.

8ea087ad16 Workload generator (Mixgraph) based on prefix hotness (#5953)
Summary:
In the previous PR https://github.com/facebook/rocksdb/issues/4788, user can use db_bench mix_graph option to generate the workload that is from the social graph. The key is generated based on the key access hotness. In this PR, user can further model the key-range hotness and fit those to two-term-exponential distribution. First, user cuts the whole key space into small key ranges (e.g., key-ranges are the same size and the key-range number is the number of SST files). Then, user calculates the average access count per key of each key-range as the key-range hotness. Next, user fits the key-range hotness to two-term-exponential distribution (f(x) = f(x) = a*exp(b*x) + c*exp(d*x)) and generate the value of a, b, c, and d. They are the parameters in db_bench: prefix_dist_a, prefix_dist_b, prefix_dist_c, and prefix_dist_d. Finally, user can run db_bench by specify the parameters.
For example:
`./db_bench --benchmarks="mixgraph" -use_direct_io_for_flush_and_compaction=true -use_direct_reads=true -cache_size=268435456 -key_dist_a=0.002312 -key_dist_b=0.3467 -keyrange_dist_a=14.18 -keyrange_dist_b=-2.917 -keyrange_dist_c=0.0164 -keyrange_dist_d=-0.08082 -keyrange_num=30 -value_k=0.2615 -value_sigma=25.45 -iter_k=2.517 -iter_sigma=14.236 -mix_get_ratio=0.85 -mix_put_ratio=0.14 -mix_seek_ratio=0.01 -sine_mix_rate_interval_milliseconds=5000 -sine_a=350 -sine_b=0.0105 -sine_d=50000 --perf_level=2 -reads=1000000 -num=5000000 -key_size=48`

50804656d2 Enable write-conflict snapshot in stress tests (#5897)
Summary:
DBImpl extends the public GetSnapshot() with GetSnapshotForWriteConflictBoundary() method that takes snapshots specially for write-write conflict checking. Compaction treats such snapshots differently to avoid GCing a value written after that, so that the write conflict remains visible even after the compaction. The patch extends stress tests with such snapshots.

a3960fc875 Move pipeline write waiting logic into WaitForPendingWrites() (#5716)
Summary:
In pipeline writing mode, memtable switching needs to wait for memtable writing to finish to make sure that when memtables are made immutable, inserts are not going to them. This is currently done in DBImpl::SwitchMemtable(). This is done after flush_scheduler_.TakeNextColumnFamily() is called to fetch the list of column families to switch. The function flush_scheduler_.TakeNextColumnFamily() itself, however, is not thread-safe when being called together with flush_scheduler_.ScheduleFlush().
This change provides a fix, which moves the waiting logic before flush_scheduler_.TakeNextColumnFamily(). WaitForPendingWrites() is a natural place where the logic can happen.

fe464bca5c Fix PlainTableReader not to crash sst_dump (#5940)
Summary:
Plain table SSTs could crash sst_dump because of a bug in
PlainTableReader that can leave table_properties_ as null. Even if it
was intended not to keep the table properties in some cases, they were
leaked on the offending code path.

Steps to reproduce:

    $ db_bench --benchmarks=fillrandom --num=2000000 --use_plain_table --prefix-size=12
    $ sst_dump --file=0000xx.sst --show_properties
    from [] to []
    Process /dev/shm/dbbench/000014.sst
    Sst file format: plain table
    Raw user collected properties
    ------------------------------
    Segmentation fault (core dumped)

Also added missing unit testing of plain table full_scan_mode, and
an assertion in NewIterator to check for regression.

Summary:
The patch adds a new command line parameter --decode_blob_index to sst_dump.
If this switch is specified, sst_dump prints blob indexes in a human readable format,
printing the blob file number, offset, size, and expiration (if applicable) for blob
references, and the blob value (and expiration) for inlined blobs.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/5926

Test Plan:
Used db_bench's BlobDB mode to generate SST files containing blob references with
and without expiration, as well as inlined blobs with and without expiration (note: the
latter are stored as plain values), and confirmed sst_dump correctly prints all four types
of records.
