      BlobDB: refactor DB open logic · 250a51a3
      由 Yi Wu 提交于 
      Summary:
Refactor BlobDB open logic. List of changes:

Major:
* On reopen, mark blob files found as immutable, do not use them for writing new keys.
* Not to scan the whole file to find file footer. Instead just seek to the end of the file and try to read footer.

Minor:
* Move most of the real logic from blob_db.cc to blob_db_impl.cc.
* Not to hold shared_ptr of event listeners in global maps in blob_db.cc
* Some changes to BlobFile interface.
* Improve logging and error handling.
Closes https://github.com/facebook/rocksdb/pull/3246

      Fix a race condition in WindowsThread (port::Thread) · fe608e32
      由 Dmitri Smirnov 提交于 
      Summary:
Fix a race condition when we create a thread and immediately destroy
 This case should be supported.
  What happens is that the thread function needs the Data instance
  to actually run but has no shared ownership and must rely on the
  WindowsThread instance to continue existing.
  To address this we change unique_ptr to shared_ptr and then
  acquire an additional refcount for the threadproc which destroys it
  just before the thread exit.
  We choose to allocate shared_ptr instance on the heap as this allows
  the original thread to continue w/o waiting for the new thread to start
  running.

      fix gflags namespace · 63f1c0a5
      由 Andrew Kryczka 提交于 
      Summary:
I started adding gflags support for cmake on linux and got frustrated that I'd need to duplicate the build_detect_platform logic, which determines namespace based on attempting compilation. We can do it differently -- use the GFLAGS_NAMESPACE macro if available, and if not, that indicates it's an old gflags version without configurable namespace so we can simply hardcode "google".

      WritePrepared Txn: PreReleaseCallback · 18dcf7f9
      由 Maysam Yabandeh 提交于 
      Summary:
Add PreReleaseCallback to be called at the end of WriteImpl but before publishing the sequence number. The callback is used in WritePrepareTxn to i) update the commit map, ii) update the last published sequence number in the 2nd write queue. It also ensures that all the commits will go to the 2nd queue.
These changes will ensure that the commit map is updated before the sequence number is published and used by reading snapshots. If we use two write queues, the snapshots will use the seq number published by the 2nd queue. If we use one write queue (the default, the snapshots will use the last seq number in the memtable, which also indicates the last published seq number.

      improve ldb CLI option support · ed3af9ef
      由 Andrew Kryczka 提交于 
      Summary:
- Made CLI arguments take precedence over options file when both are provided. Note some of the CLI args are not settable via options file, like `--compression_max_dict_bytes`, so it's necessary to allow both ways of providing options simultaneously.
- Changed `PrepareOptionsForOpenDB` to update the proper `ColumnFamilyOptions` if one exists for the user's `--column_family_name` argument. I supported this only in the base class, `LDBCommand`, so it works for the general arguments. Will defer adding support for subcommand-specific arguments.
- Made the command fail if `--try_load_options` is provided and loading options file returns NotFound. I found the previous behavior of silently continuing confusing.

      convert null terminator in ascii dump · c85f8ccc
      由 Andrew Kryczka 提交于 
      Summary:
The ASCII output is almost always useless to me as the first '\0' byte in the key or value causes it to stop printing. Since all characters are already surrounded by spaces, "\ 0" (how we display a backslash followed by a zero) and "\0" (how this PR displays a null terminator) are distinguishable. My assumption is the value of seeing all the bytes outweighs the value of the alignment we had before, where we always had one character followed by one space.

      Fix IOError on WAL write doesn't propagate to write group follower · 3cf562be
      由 Yi Wu 提交于 
      Summary:
This is a simpler version of #3097 by removing all unrelated changes.

Fixing the bug where concurrent writes may get Status::OK while it actually gets IOError on WAL write. This happens when multiple writes form a write batch group, and the leader get an IOError while writing to WAL. The leader failed to pass the error to followers in the group, and the followers end up returning Status::OK() while actually writing nothing. The bug only affect writes in a batch group. Future writes after the batch group will correctly return immediately with the IOError.

      optimize file ingestion checks for range deletion overlap · 1bdb44de
      由 Andrew Kryczka 提交于 
      Summary:
Before we were checking every file in the level which was unnecessary. We can piggyback onto the code for checking point-key overlap, which already opens all the files that could possibly contain overlapping range deletions. This PR makes us check just the range deletions from those files, so no extra ones will be opened.

      Support for block_cache num_shards and other config via option string. · 4b65cfc7
      由 Phani Shekhar Mantripragada 提交于 
      Summary:
Problem: Option string accepts only cache_size as parameter for block_cache which is specified as "block_cache=1M".
It doesn't accept other parameters like num_shards etc.

Changes :
1) ParseBlockBasedTableOption in block_based_table_factory is edited to accept cache options in the format "block_cache=<cache_size>:<num_shard_bits>:<strict_capacity_limit>:<high_pri_pool_ratio>".
Options other than cache_size are optional to maintain backward compatibility. The changes are valid for block_cache_compressed as well.
For example, "block_cache=1M:6:true:0.5", "block_cache=1M:6:true", "block_cache=1M:6" and "block_cache=1M" are all valid option strings.

2) Corresponding unit tests are added.
