Yanqin Jin 3bea276fc8 Do not print u'string' in TARGETS file (#6841)
Summary:
Before this PR, extra deps passed in from cmd line to buckifier will be parsed

Tongliang Liao 244797aa4b Add `find_dependency()` in cmake config file. (#6791)
Summary:
Currently when building PyTorch with latest RocksDB we get errors like "missing target Snappy::snappy", because they are simply not there.
With old `${VAR}` approach we essentially hard-code the abs path found during RocksDB build, which is:
 - Not relocatable.
 - Doesn't work when changed to modern target-based design because that requires target to present when used for expansion.

This fix allows cmake to setup imported target, if enabled during RocksDB build, when downstream uses `find_package(RocksDB)`.

This is for https://github.com/facebook/rocksdb/issues/6179

sdong 4a4b8a1344 sst_dump to reduce number of file reads (#6836)
Summary:
sst_dump can issue many file reads from the file system. This doesn't work well with file systems without a OS cache, especially remote file systems. In order to mitigate this problem, several improvements are done:
1. --readahead_size is added, so that users can specify readahead size when scanning the data.
2. Force a 512KB tail readahead, which prevents three I/Os for footer, meta index and property blocks and hopefully index and filter blocks too.
3. Consoldiate SSTDump's I/Os before opening the file for read. Use the same file prefetch buffer.

Test Plan: Add a test that covers this new feature.

Ziyue Yang c384c08a4f Add tests for compression failure in BlockBasedTableBuilder (#6709)
Summary:
Currently there is no check for whether BlockBasedTableBuilder will expose
compression error status if compression fails during the table building.
This commit adds fake faulting compressors and a unit test to test such
cases.

This check finds 5 bugs, and this commit also fixes them:

1. Not handling compression failure well in
   BlockBasedTableBuilder::BGWorkWriteRawBlock.
2. verify_compression failing in BlockBasedTableBuilder when used with ZSTD.
3. Wrongly passing the same reference of block contents to
   BlockBasedTableBuilder::CompressAndVerifyBlock in parallel compression.
4. Wrongly setting block_rep->first_key_in_next_block to nullptr in
   BlockBasedTableBuilder::EnterUnbuffered when there are still incoming data
   blocks.
5. Not maintaining variables for compression ratio estimation and first_block
   in BlockBasedTableBuilder::EnterUnbuffered.

Added a way to run tests (`ASSERT_STATUS_CHECKED=1 make -j48 check`) on a

this assertion, so I only fixed up enough to get one test (`options_test`)

anand76 94265234de Fix race due to delete triggered compaction in Universal compaction mode (#6799)
Summary:
Delete triggered compaction in universal compaction mode was causing a corruption when scheduled in parallel with other compactions.
1. When num_levels = 1, a file marked for compaction may be picked along with all older files in L0, without checking if any of them are already being compaction. This can cause unpredictable results like resurrection of older versions of keys or deleted keys.
2. When num_levels > 1, a delete triggered compaction would not get scheduled if it overlaps with a running regular compaction. However, the reverse is not true. This is due to the fact that in ```UniversalCompactionBuilder::CalculateSortedRuns```, it assumes that entire sorted runs are picked for compaction and only checks the first file in a sorted run to determine conflicts. This is violated by a delete triggered compaction as it works on a subset of a sorted run.

Fix the bug for num_levels > 1, and disable the feature for now when num_levels = 1. After disabling this feature, files would still get marked for compaction, but no compaction would get scheduled.

identifies and purges obsolete files to blob files handled by RocksDB

the storage directories used by the base DB. (Note: this is true by default.)
The patch adds a check that explicitly disallows this configuration and
returns `Status::NotSupported` from `BlobDB::Open` in such cases.

Summary:
Add methods and constructors for handling enums to the OptionTypeInfo.  This change allows enums to be converted/compared without adding a special "type" to the OptionType.

This change addresses a couple of issues:
- It allows new enumerated types to be added to the options without editing the OptionType base class (and related methods)
- It standardizes the procedure for adding enumerated types to the options, reducing potential mistakes
- It moves the enum maps to the location where they are used, allowing them to be static file members rather than global values
- It reduces the number of types and cases that need to be handled in the various OptionType methods

Yanqin Jin 5a61e7864d Fix db_stress when GetLiveFiles() flushes dropped CF (#6805)
Summary:
Current impl. of db_stress will abort verification and report failure if
GetLiveFiles() causes a dropped column family to be flushed. This is not
desired.
To fix, this PR makes the following change:
In GetLiveFiles, if flush is triggered and returns
Status::IsColumnFamilyDropped(), then set status to Status::OK().
This is OK because dropped column families will be skipped during the rest of
this function, and valid column families will have their live files returned to
caller.

Levi Tamasi a00ddf1574 Expose the set of live blob files from Version/VersionSet (#6785)
Summary:
The patch adds logic that returns the set of live blob files from
`Version::AddLiveFiles` and `VersionSet::AddLiveFiles` (in addition to
live table files), and also cleans up the code a bit, for example, by
exposing only the numbers of table files as opposed to the earlier
`FileDescriptor`s that no clients used. Moreover, the patch extends
the `GetLiveFiles` API so that it also exposes blob files in the current version.
Similarly to https://github.com/facebook/rocksdb/pull/6755,
this is a building block for identifying and purging obsolete blob files.

1, add a separate random mode in MixGraph to produce all_random workload.
2, fix power inverse function for generating prefix_dist workload.
3, make sure key_offset in prefix mode is always unsigned.
note: Need to carefully choose key_dist_a/b to avoid aliasing. Power inverse function range should be close to overall key space.

Yanqin Jin 6acbbbf9fc Add Github Action for some basic sanity test of PR (#6761)
Summary:
Add Github Action to perform some basic sanity check for PR, inclding the
following.
1) Buck TARGETS file.
On the one hand, The TARGETS file is used for internal buck, and we do not
manually update it. On the other hand, we need to run the buckifier scripts to
update TARGETS whenever new files are added, etc. With this Github Action, we
make sure that every PR does not forget this step. The GH Action uses
a Makefile target called check-buck-targets. Users can manually run `make
check-buck-targets` on local machine.

2) Code format
We use clang-format-diff.py to format our code. The GH Action in this PR makes
sure this step is not skipped. The checking script build_tools/format-diff.sh assumes that `clang-format-diff.py` is executable.
On host running GH Action, it is difficult to download `clang-format-diff.py` and make it
executable. Therefore, we modified build_tools/format-diff.sh to handle the case in which there is a non-executable clang-format-diff.py file in the top-level rocksdb repo directory.

Test Plan (Github and devserver):
Watch for Github Action result in the `Checks` tab.
On dev server
```
make check-format
make check-buck-targets
make check
```

Summary:
The current way of implementing CompressionOptions.parallel_threads introduces a format change. We plan to change CompressionOptions's serailization format to a new JSON-like format, which would be another format change. We would like to consolidate the two format changes into one, rather than making some users to change twice. Hold CompressionOptions.parallel_threads from being supported by option string for now. Will add it back after the general CompressionOptions's format change.

Cheng Chang ef0c3eda27 Make users explicitly be aware of prepare before commit (#6775)
Summary:
In current commit protocol of pessimistic transaction, if the transaction is not prepared before commit, the commit protocol implicitly assumes that the user wants to commit without prepare.

This PR adds TransactionOptions::skip_prepare, the default value is `true` because if set to `false`, all existing users who commit without prepare need to update their code to set skip_prepare to true. Although this does not force the user to explicitly express their intention of skip_prepare, it at least lets the user be aware of the assumption of being able to commit without prepare.

sdong 079e50d2ba Disallow BlockBasedTableBuilder to set status from non-OK (#6776)
Summary:
There is no systematic mechanism to prevent BlockBasedTableBuilder's status to be set from non-OK to OK. Adding a mechanism to force this will help us prevent failures in the future.

The solution is to only make it possible to set the status code if the status code to set is not OK.

Since the status code passed to CompressAndVerifyBlock() is changed, a mini refactoring is done too so that the output arguments are changed from reference to pointers, based on Google C++ Style.

anand76 ab13d43e1d Pass a timeout to FileSystem for random reads (#6751)
Summary:
Calculate ```IOOptions::timeout``` using ```ReadOptions::deadline``` and pass it to ```FileSystem::Read/FileSystem::MultiRead```. This allows us to impose a tighter bound on the time taken by Get/MultiGet on FileSystem/Envs that support IO timeouts. Even on those that don't support, check in ```RandomAccessFileReader::Read``` and ```MultiRead``` and return ```Status::TimedOut()``` if the deadline is exceeded.

For now, TableReader creation, which might do file opens and reads, are not covered. It will be implemented in another PR.

Tests:
Update existing unit tests to verify the correct timeout value is being passed

Levi Tamasi fe238e5438 Keep track of obsolete blob files in VersionSet (#6755)
Summary:
The patch adds logic to keep track of obsolete blob files. A blob file becomes
obsolete when the last `shared_ptr` that points to the corresponding
`SharedBlobFileMetaData` object goes away, which, in turn, happens when the
last `Version` that contains the blob file is destroyed. No longer needed blob
files are added to the obsolete list in `VersionSet` using a custom deleter to
avoid unnecessary coupling between `SharedBlobFileMetaData` and `VersionSet`.
Obsolete blob files are returned by `VersionSet::GetObsoleteFiles` and stored
in `JobContext`.
