      db_stress: skip snapshot check if cf is dropped · 95583e15
      由 Maysam Yabandeh 提交于 
      Summary:
We added a new verification that ensures a value that snapshot reads when is released is the same as when it was created. This test however fails when the cf is dropped in between. The patch skips the tests if that was the case.

      BlobDB: Remove the need to get sequence number per write · 237b2925
      由 Yi Wu 提交于 
      Summary:
Previously we store sequence number range of each blob files, and use the sequence number range to check if the file can be possibly visible by a snapshot. But it adds complexity to the code, since the sequence number is only available after a write. (The current implementation get sequence number by calling GetLatestSequenceNumber(), which is wrong.) With the patch, we are not storing sequence number range, and check if snapshot_sequence < obsolete_sequence to decide if the file is visible by a snapshot (previously we check if first_sequence <= snapshot_sequence < obsolete_sequence).

      fix backup meta-file buffer overrun · a79c7c05

- check most times after calling snprintf that the buffer didn't fill up. Previously we'd proceed and use `buf_size - len` as the length in subsequent calls, which underflowed as those are unsigned size_t.
- replace some memcpys with snprintf for consistency

* 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.

      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.
