Summary: * Adds backup/restore forward/backward compatibility testing * Adds forward/backward compatibility testing to sst ingestion * More structure sharing and comments for the lists of branches comprising each group * Less reliant on invariants between groups with de-duplication logic * Restructured for n+1 branch checkout+build steps rather than something like 3n. Should be much faster despite more checks. And to make manual runs easier * On success, restores working trees to original working branch (aborts early if uncommitted changes) and deletes temporary branch & remote * Adds SHORT_TEST=1 mode that uses only the oldest version for each * Adds USE_SSH=1 to use ssh instead of https for github group Pull Request resolved: https://github.com/facebook/rocksdb/pull/8012 Test Plan: a number of manual tests, mostly with SHORT_TEST=1. Using one version older for any of the groups (except I didn't check db_backward_only_refs) fails. Changing default format_version to 5 (planned) without updating this script fails as it should, and passes with appropriate update. Full local run passed (had to remove "2.7.fb.branch" due to compiler issues, also before this change).

Summary: The patch breaks down the "bytes written" (as well as the "number of output files") compaction statistics into two, so the values are logged separately for table files and blob files in the info log, and are shown in separate columns (`Write(GB)` for table files, `Wblob(GB)` for blob files) when the compaction statistics are dumped. This will also come in handy for fixing the write amplification statistics, which currently do not consider the amount of data read from blob files during compaction. (This will be fixed by an upcoming patch.) Pull Request resolved: https://github.com/facebook/rocksdb/pull/8013 Test Plan: Ran `make check` and `db_bench`.

Summary: This is likely a temp fix before we figure out a better way. PerfStepTimer is used intensively in certain benchmarking/testings. https://github.com/facebook/rocksdb/issues/7858 stores a `shared_ptr` to system clock in PerfStepTimer which gets created each time a `PerfStepTimer` object is created. The atomic operations in `shared_ptr` may add overhead in CPU cycles. Therefore, we change it back to a raw `SystemClock*` for now.

Summary: This change only affects non-schema-critical aspects of the production candidate Ribbon filter. Specifically, it refines choice of internal configuration parameters based on inputs. The changes are minor enough that the schema tests in bloom_test, some of which depend on this, are unaffected. There are also some minor optimizations and refactorings. This would be a schema change for "smash" Ribbon, to fix some known issues with small filters, but "smash" Ribbon is not accessible in public APIs. Unit test CompactnessAndBacktrackAndFpRate updated to test small and medium-large filters. Run with --thoroughness=100 or so for much better detection power (not appropriate for continuous regression testing). Homogenous Ribbon: This change adds internally a Ribbon filter variant we call Homogeneous Ribbon, in collaboration with Stefan Walzer. The expected "result" value for every key is zero, instead of computed from a hash. Entropy for queries not to be false positives comes from free variables ("overhead") in the solution structure, which are populated pseudorandomly. Construction is slightly faster for not tracking result values, and never fails. Instead, FP rate can jump up whenever and whereever entries are packed too tightly. For small structures, we can choose overhead to make this FP rate jump unlikely, as seen in updated unit test CompactnessAndBacktrackAndFpRate. Unlike standard Ribbon, Homogeneous Ribbon seems to scale to arbitrary number of keys when accepting an FP rate penalty for small pockets of high FP rate in the structure. For example, 64-bit ribbon with 8 solution columns and 10% allocated space overhead for slots seems to achieve about 10.5% space overhead vs. information-theoretic minimum based on its observed FP rate with expected pockets of degradation. (FP rate is close to 1/256.) If targeting a higher FP rate with fewer solution columns, Homogeneous Ribbon can be even more space efficient, because the penalty from degradation is relatively smaller. If targeting a lower FP rate, Homogeneous Ribbon is less space efficient, as more allocated overhead is needed to keep the FP rate impact of degradation relatively under control. The new OptimizeHomogAtScale tool in ribbon_test helps to find these optimal allocation overheads for different numbers of solution columns. And Ribbon widths, with 128-bit Ribbon apparently cutting space overheads in half vs. 64-bit. Other misc item specifics: * Ribbon APIs in util/ribbon_config.h now provide configuration data for not just 5% construction failure rate (95% success), but also 50% and 0.1%. * Note that the Ribbon structure does not exhibit "threshold" behavior as standard Xor filter does, so there is a roughly fixed space penalty to cut construction failure rate in half. Thus, there isn't really an "almost sure" setting. * Although we can extrapolate settings for large filters, we don't have a good formula for configuring smaller filters (< 2^17 slots or so), and efforts to summarize with a formula have failed. Thus, small data is hard-coded from updated FindOccupancy tool. * Enhances ApproximateNumEntries for public API Ribbon using more precise data (new API GetNumToAdd), thus a more accurate but not perfect reversal of CalculateSpace. (bloom_test updated to expect the greater precision) * Move EndianSwapValue from coding.h to coding_lean.h to keep Ribbon code easily transferable from RocksDB * Add some missing 'const' to member functions * Small optimization to 128-bit BitParity * Small refactoring of BandingStorage in ribbon_alg.h to support Homogeneous Ribbon * CompactnessAndBacktrackAndFpRate now has an "expand" test: on construction failure, a possible alternative to re-seeding hash functions is simply to increase the number of slots (allocated space overhead) and try again with essentially the same hash values. (Start locations will be different roundings of the same scaled hash values--because fastrange not mod.) This seems to be as effective or more effective than re-seeding, as long as we increase the number of slots (m) by roughly m += m/w where w is the Ribbon width. This way, there is effectively an expansion by one slot for each ribbon-width window in the banding. (This approach assumes that getting "bad data" from your hash function is as unlikely as it naturally should be, e.g. no adversary.) * 32-bit and 16-bit Ribbon configurations are added to ribbon_test for understanding their behavior, e.g. with FindOccupancy. They are not considered useful at this time and not tested with CompactnessAndBacktrackAndFpRate.

Summary: Allow applications to implement a custom compaction filter and pass it to BlobDB. The compaction filter's custom logic can operate on blobs. To do so, application needs to subclass `CompactionFilter` abstract class and implement `FilterV2()` method. Optionally, a method called `ShouldFilterBlobByKey()` can be implemented if application's custom logic rely solely on the key to make a decision without reading the blob, thus saving extra IO. Examples can be found in db/blob/db_blob_compaction_test.cc.

Summary: In the adapter class `WritableFileStringStreamAdapter`, which wraps WritableFile to be used for std::ostream, previouly only `std::endl` is considered a special case because `endl` is written by `os.put()` directly without going through `xsputn()`. `os.put()` will call `sputc()` and if we further check the internal implementation of `sputc()`, we will see it is ``` int_type __CLR_OR_THIS_CALL sputc(_Elem _Ch) { // put a character return 0 < _Pnavail() ? _Traits::to_int_type(*_Pninc() = _Ch) : overflow(_Traits::to_int_type(_Ch)); ``` As we explicitly disabled buffering, _Pnavail() is always 0. Thus every write, not captured by xsputn, becomes an overflow. When I run tests on Windows, I found not only `std::endl` will drop into this case, writing an unsigned long long will also call `os.put()` then followed by `sputc()` and eventually call `overflow()`. Therefore, instead of only checking `std::endl`, we should try to append other characters as well unless the appending operation fails.

Summary: RocksDB does auto-readahead for iterators on noticing more than two reads for a table file. The readahead starts at 8KB and doubles on every additional read upto BlockBasedTable::kMaxAutoReadAheadSize which is 256*1024. This PR adds a new option BlockBasedTableOptions::max_auto_readahead_size which replaces BlockBasedTable::kMaxAutoReadAheadSize and the new option can be configured. If max_auto_readahead_size is set 0 then no implicit auto prefetching will be done. If max_auto_readahead_size provided is less than 8KB (which is initial readahead size used by rocksdb in case of auto-readahead), readahead size will remain same as max_auto_readahead_size.

Summary: Fixed 5 test case failures found on Windows 10/Windows Server 2016 1. In `flush_job_test`, the DestroyDir function fails in deconstructor because some file handles are still being held by VersionSet. This happens on Windows Server 2016, so need to manually reset versions_ pointer to release all file handles. 2. In `StatsHistoryTest.InMemoryStatsHistoryPurging` test, the capping memory cost of stats_history_size on Windows becomes 14000 bytes with latest changes, not just 13000 bytes. 3. In `SSTDumpToolTest.RawOutput` test, the output file handle is not closed at the end. 4. In `FullBloomTest.OptimizeForMemory` test, ROCKSDB_MALLOC_USABLE_SIZE is undefined on windows so `total_mem` is always equal to `total_size`. The internal memory fragmentation assertion does not apply in this case. 5. In `BlockFetcherTest.FetchAndUncompressCompressedDataBlock` test, XPRESS cannot reach 87.5% compression ratio with original CreateTable method, so I append extra zeros to the string value to enhance compression ratio. Beside, since XPRESS allocates memory internally, thus does not support for custom allocator verification, we will skip the allocator verification for XPRESS Pull Request resolved: https://github.com/facebook/rocksdb/pull/7992 Reviewed By: jay-zhuang Differential Revision: D26615283 Pulled By: ajkr fbshipit-source-id: 3632612f84b99e2b9c77c403b112b6bedf3b125d

Summary: For dictionary compression, we need to collect some representative samples of the data to be compressed, which we use to either generate or train (when `CompressionOptions::zstd_max_train_bytes > 0`) a dictionary. Previously, the strategy was to buffer all the data blocks during flush, and up to the target file size during compaction. That strategy allowed us to randomly pick samples from as wide a range as possible that'd be guaranteed to land in a single output file. However, some users try to make huge files in memory-constrained environments, where this strategy can cause OOM. This PR introduces an option, `CompressionOptions::max_dict_buffer_bytes`, that limits how much data blocks are buffered before we switch to unbuffered mode (which means creating the per-SST dictionary, writing out the buffered data, and compressing/writing new blocks as soon as they are built). It is not strict as we currently buffer more than just data blocks -- also keys are buffered. But it does make a step towards giving users predictable memory usage. Related changes include: - Changed sampling for dictionary compression to select unique data blocks when there is limited availability of data blocks - Made use of `BlockBuilder::SwapAndReset()` to save an allocation+memcpy when buffering data blocks for building a dictionary - Changed `ParseBoolean()` to accept an input containing characters after the boolean. This is necessary since, with this PR, a value for `CompressionOptions::enabled` is no longer necessarily the final component in the `CompressionOptions` string. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7970 Test Plan: - updated `CompressionOptions` unit tests to verify limit is respected (to the extent expected in the current implementation) in various scenarios of flush/compaction to bottommost/non-bottommost level - looked at jemalloc heap profiles right before and after switching to unbuffered mode during flush/compaction. Verified memory usage in buffering is proportional to the limit set.

Summary: The current implementation of a binary heap in `util/heap.h` does a move-assign in the `pop` method. In the case that there is exactly one element stored in the heap, this ends up being a self-move-assign. This can cause trouble with certain classes, which are not prepared for this. Furthermore, it trips up the glibc STL debugger (`-D_GLIBCXX_DEBUG`), which produces an assertion failure in this case. This PR addresses this problem by not doing the (unnecessary in this case) move-assign if there is only one element in the heap.

Summary: TransactionDB uses read callback to filter out un-committed data before a snapshot. But `MultiGet()` API doesn't use that at all, which causes returning unwanted data.

Summary: The patch adds checkpoint support to BlobDB. Blob files are hard linked or copied, depending on whether the checkpoint directory is on the same filesystem or not, similarly to table files. TODO: Add support for blob files to `ExportColumnFamily` and to the checksum verification logic used by backup/restore. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7959 Test Plan: Ran `make check` and the crash test for a while.
