      FlushReason improvement · 1cbc96d2
      由 Zhongyi Xie 提交于 
      Summary:
Right now flush reason "SuperVersion Change" covers a few different scenarios which is a bit vague. For example, the following db_bench job should trigger "Write Buffer Full"

> $ TEST_TMPDIR=/dev/shm ./db_bench -benchmarks=fillrandom -write_buffer_size=1048576 -target_file_size_base=1048576 -max_bytes_for_level_base=4194304
$ grep 'flush_reason' /dev/shm/dbbench/LOG

      WritePrepared Txn: fix race condition on publishing seq · 7429b20e
      由 Maysam Yabandeh 提交于 
      Summary:
This commit fixes a race condition on calling SetLastPublishedSequence. The function must be called only from the 2nd write queue when two_write_queues is enabled. However there was a bug that would also call it from the main write queue if CommitTimeWriteBatch is provided to the commit request and yet use_only_the_last_commit_time_batch_for_recovery optimization is not enabled. To fix that we penalize the commit request in such cases by doing an additional write solely to publish the seq number from the 2nd queue.

      由 Yanqin Jin 提交于 
      Summary:
In original $ROCKSDB_HOME/Makefile, the command used to generate ctags is
```
ctags * -R
```
However, this failed to generate tags for me.
I did some search on the usage of ctags command and found that it should be
```
ctags -R .
```
or
```
ctags -R *
```
After the change, I can find the tags in vim using `:ts <identifier>`.

      Fix WAL corruption from checkpoint/backup race condition · 0cdaa1a8
      由 Andrew Kryczka 提交于 
      Summary:
`Writer::WriteBuffer` was always called at the beginning of checkpoint/backup. But that log writer has no internal synchronization, which meant the same buffer could be flushed twice in a race condition case, causing a WAL entry to be duplicated. Then subsequent WAL entries would be at unexpected offsets, causing the 32KB block boundaries to be overlapped and manifesting as a corruption.

This PR fixes the behavior to only use `WriteBuffer` (via `FlushWAL`) in checkpoint/backup when manual WAL flush is enabled. In that case, users are responsible for providing synchronization between WAL flushes. We can also consider removing the call entirely.
