      Add the integrated BlobDB to the stress/crash tests (#7900) · 0288bdbc
      由 Levi Tamasi 提交于 
      Summary:
The patch adds support for the options related to the new BlobDB implementation
to `db_stress`, including support for dynamically adjusting them using `SetOptions`
when `set_options_one_in` and a new flag `allow_setting_blob_options_dynamically`
are specified. (The latter is used to prevent the options from being enabled when
incompatible features are in use.)

The patch also updates the `db_stress` help messages of the existing stacked BlobDB
related options to clarify that they pertain to the old implementation. In addition, it
adds the new BlobDB to the crash test script. In order to prevent a combinatorial explosion
of jobs and still perform whitebox/blackbox testing (including under ASAN/TSAN/UBSAN),
and to also test BlobDB in conjunction with atomic flush and transactions, the script sets
the BlobDB options in 10% of normal/`cf_consistency`/`txn` crash test runs.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7900

Test Plan: Ran `make check` and `db_stress`/`db_crashtest.py` with various options.

      Fix a SingleDelete related optimization for blob indexes (#7904) · e5311a8e
      由 Levi Tamasi 提交于 
      Summary:
There is a small `SingleDelete` related optimization in the
`CompactionIterator` code: when a `SingleDelete`-`Put` pair is preserved
solely for the purposes of transaction conflict checking, the value
itself gets cleared. (This is referred to as "optimization 3" in the
`CompactionIterator` code.) Though the rest of the code got updated to
support `SingleDelete`'ing blob indexes, this chunk was apparently
missed, resulting in an assertion failure (or `ROCKS_LOG_FATAL` in release
builds) when triggered. Note: in addition to clearing the value, we also
need to update the type of the KV to regular value when dealing with
blob indexes here.

      Integrity protection for live updates to WriteBatch (#7748) · 78ee8564
      由 Andrew Kryczka 提交于 
      Summary:
This PR adds the foundation classes for key-value integrity protection and the first use case: protecting live updates from the source buffers added to `WriteBatch` through the destination buffer in `MemTable`. The width of the protection info is not yet configurable -- only eight bytes per key is supported. This PR allows users to enable protection by constructing `WriteBatch` with `protection_bytes_per_key == 8`. It does not yet expose a way for users to get integrity protection via other write APIs (e.g., `Put()`, `Merge()`, `Delete()`, etc.).

The foundation classes (`ProtectionInfo.*`) embed the coverage info in their type, and provide `Protect.*()` and `Strip.*()` functions to navigate between types with different coverage. For making bytes per key configurable (for powers of two up to eight) in the future, these classes are templated on the unsigned integer type used to store the protection info. That integer contains the XOR'd result of hashes with independent seeds for all covered fields. For integer fields, the hash is computed on the raw unadjusted bytes, so the result is endian-dependent. The most significant bytes are truncated when the hash value (8 bytes) is wider than the protection integer.

When `WriteBatch` is constructed with `protection_bytes_per_key == 8`, we hold a `ProtectionInfoKVOTC` (i.e., one that covers key, value, optype aka `ValueType`, timestamp, and CF ID) for each entry added to the batch. The protection info is generated from the original buffers passed by the user, as well as the original metadata generated internally. When writing to memtable, each entry is transformed to a `ProtectionInfoKVOTS` (i.e., dropping coverage of CF ID and adding coverage of sequence number), since at that point we know the sequence number, and have already selected a memtable corresponding to a particular CF. This protection info is verified once the entry is encoded in the `MemTable` buffer.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7748

Test Plan:
- an integration test to verify a wide variety of single-byte changes to the encoded `MemTable` buffer are caught
- add to stress/crash test to verify it works in variety of configs/operations without intentional corruption
- [deferred] unit tests for `ProtectionInfo.*` classes for edge cases like KV swap, `SliceParts` and `Slice` APIs are interchangeable, etc.

      Remove Legacy and Custom FileWrapper classes from header files (#7851) · 4a09d632
      由 mrambacher 提交于 
      Summary:
Removed the uses of the Legacy FileWrapper classes from the source code.  The wrappers were creating an additional layer of indirection/wrapping, as the Env already has a FileSystem.

Moved the Custom FileWrapper classes into the CustomEnv, as these classes are really for the private use the the CustomEnv class.

      Make builds reproducible (#7866) · 0a9a05ae
      由 mrambacher 提交于 
      Summary:
Closes https://github.com/facebook/rocksdb/issues/7035

Changed how build_version.cc was generated:
- Included the GIT tag/branch in the build_version file
- Changed the "Build Date" to be:
      - If the GIT branch is "clean" (no changes), the date of the last git commit
      - If the branch is not clean, the current date
 - Added APIs to access the "build information", rather than accessing the strings directly.

The build_version.cc file is now regenerated whenever the library objects are rebuilt.

Verified that the built files remain the same size across builds on a "clean build" and the same information is reported by sst_dump --version

      Add a SystemClock class to capture the time functions of an Env (#7858) · 12f11373
      由 mrambacher 提交于 
      Summary:
Introduces and uses a SystemClock class to RocksDB.  This class contains the time-related functions of an Env and these functions can be redirected from the Env to the SystemClock.

Many of the places that used an Env (Timer, PerfStepTimer, RepeatableThread, RateLimiter, WriteController) for time-related functions have been changed to use SystemClock instead.  There are likely more places that can be changed, but this is a start to show what can/should be done.  Over time it would be nice to migrate most (if not all) of the uses of the time functions from the Env to the SystemClock.

There are several Env classes that implement these functions.  Most of these have not been converted yet to SystemClock implementations; that will come in a subsequent PR.  It would be good to unify many of the Mock Timer implementations, so that they behave similarly and be tested similarly (some override Sleep, some use a MockSleep, etc).

Additionally, this change will allow new methods to be introduced to the SystemClock (like https://github.com/facebook/rocksdb/issues/7101 WaitFor) in a consistent manner across a smaller number of classes.

      In IOTracing, add filename with each operation in trace file. (#7885) · 1d226018
      由 Akanksha Mahajan 提交于 
      Summary:
1. In IOTracing, add filename with each IOTrace record. Filename is stored in file object (Tracing Wrappers).
         2. Change the logic of figuring out which additional information (file_size,
            length, offset etc) needs to be store with each operation
            which is different for different operations.
            When new information will be added in future (depends on operation),
            this change would make the future additions simple.

Logic: In IOTraceRecord, io_op_data is added and its
         bitwise positions represent which additional information need
         to added in the record from enum IOTraceOp. Values in IOTraceOp represent bitwise positions.
         So if length and offset needs to be stored (IOTraceOp::kIOLen
         is 1 and IOTraceOp::kIOOffset is 2), position 1 and 2 (from rightmost bit) will be set
         and io_op_data will contain 110.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7885

Test Plan: Updated io_tracer_test and verified the trace file manually.

      Do not explicitly flush blob files when using the integrated BlobDB (#7892) · 431e8afb
      由 Levi Tamasi 提交于 
      Summary:
In the original stacked BlobDB implementation, which writes blobs to blob files
immediately and treats blob files as logs, it makes sense to flush the file after
writing each blob to protect against process crashes; however, in the integrated
implementation, which builds blob files in the background jobs, this unnecessarily
reduces performance. This patch fixes this by simply adding a `do_flush` flag to
`BlobLogWriter`, which is set to `true` by the stacked implementation and to `false`
by the new code. Note: the change itself is trivial but the tests needed some work;
since in the new implementation, blobs are now buffered, adding a blob to
`BlobFileBuilder` is no longer guaranteed to result in an actual I/O. Therefore, we can
no longer rely on `FaultInjectionTestEnv` when testing failure cases; instead, we
manipulate the return values of I/O methods directly using `SyncPoint`s.
