      Fix WinEnv::NowMicrosec · 555ca3e7
      由 Dmitri Smirnov 提交于 
        * std::chrono does not provide enough granularity for microsecs and periodically emits
    duplicates
  * the bug is manifested in log rotation logic where we get duplicate
   log file names and loose previous log content
  * msvc does not imlement COW on std::strings adjusted the test to use
    refs in the loops as auto does not retain ref info
  * adjust auto_log rotation test with Windows specific command to remove
    a folder. The test previously worked because we have unix utils installed
    in house but this may not be the case for everyone.

      [wal changes 2/3] write with sync=true syncs previous unsynced wals to prevent illegal data loss · fe09a6da
      由 Mike Kolupaev 提交于 
      Summary:
I'll just copy internal task summary here:

"
This sequence will cause data loss in the middle after an sync write:

non-sync write key 1
flush triggered, not yet scheduled
sync write key 2
system crash

After rebooting, users might see key 2 but not key 1, which violates the API of sync write.

This can be reproduced using unit test FaultInjectionTest::DISABLED_WriteOptionSyncTest.

One way to fix it is for a sync write, if there is outstanding unsynced log files, we need to syc them too.
"

This diff should be considered together with the next diff D40905; in isolation this fix probably could be a little simpler.

Test Plan: `make check`; added a test for that (DBTest.SyncingPreviousLogs) before noticing FaultInjectionTest.WriteOptionSyncTest (keeping both since mine asserts a bit more); both tests fail without this diff; for D40905 stacked on top of this diff, ran tests with ASAN, TSAN and valgrind

      Summary:
Fixes T6548822. Added a new function for estimating the size of the live data
as proposed in the task. The value can be accessed through the property
rocksdb.estimate-live-data-size.

Test Plan:
There are two unit tests in version_set_test and a simple test in db_test.
make version_set_test && ./version_set_test;
make db_test && ./db_test gtest_filter=GetProperty

      RangeSync not to sync last 1MB of the file · 3dbf4ba2
      由 Siying Dong 提交于 
      Summary:
From other ones' investigation:

"sync_file_range() behavior highly depends on kernel version and filesystem.

xfs does neighbor page flushing outside of the specified ranges. For example, sync_file_range(fd, 8192, 16384) does not only trigger flushing page #3 to #4, but also flushing many more dirty pages (i.e. up to page#16)... Ranges of the sync_file_range() should be far enough from write() offset (at least 1MB)."

      Move rate_limiter, write buffering, most perf context instrumentation and most random kill out of Env

Summary: We want to keep Env a think layer for better portability. Less platform dependent codes should be moved out of Env. In this patch, I create a wrapper of file readers and writers, and put rate limiting, write buffering, as well as most perf context instrumentation and random kill out of Env. It will make it easier to maintain multiple Env in the future.

Test Plan: Run all existing unit tests.

      Don't let flushes preempt compactions · 35ca5936
      由 Igor Canadi 提交于 
      Summary:
When we first started, max_background_flushes was 0 by default and compaction thread was executing flushes (since there was no flush thread). Then, we switched the default max_background_flushes to 1. However, we still support the case where there is no flush thread and flushes are done in compaction. This is making our code a bit more complicated. By not supporting this use-case we can make our code simpler.

We have a special case that when you set max_background_flushes to 0, we
schedule the flush to execute on the compaction thread.

Test Plan: make check (there might be some unit tests that depend on this behavior)

      Fix ROCKSDB_WARNING · 79373c37
      由 agiardullo 提交于 
      Summary:
ROCKSDB_WARNING is only defined if either ROCKSDB_PLATFORM_POSIX or OS_WIN is defined.  This works well for building rocksdb with its own build scripts.  But this won't work when an outside project(like mongodb) doesn't define ROCKSDB_PLATFORM_POSIX.

This fix defines ROCKSDB_WARNING for all platforms.  No idea if its defined correctly on non-posix,non-windows platforms but this is no worse that the current situation where this macro is missing on unexpected platforms.

This fix should hopefully fix anyone whose build broke now that we've switched from using #warning to Pragma (to support windows).  Unfortunately, while mongo-rocks compiles, it ignores the Pragma and doesn't print a warning.  I have not been able to figure out a way to implement this portably on all platforms.

Of course, an alternate solution would be to just get rid of ROCKSDB_WARNING and live with include file redirects indefinitely.  Thoughts?

Test Plan: build rocks, build mongorocks

      Fixed and simplified merge_helper · 1d20fa9d
      由 Andres Notzli 提交于 
      Summary:
MergeUntil was not reporting a success when merging an operand with
a Value/Deletion despite the comments in MergeHelper and CompactionJob
indicating otherwise. This lead to operands being written to the compaction
output unnecessarily:

M1 M2 M3 P M4 M5 --> (P+M1+M2+M3) M2 M3 M4 M5 (before the diff)
M1 M2 M3 P M4 M5 --> (P+M1+M2+M3) M4 M5 (after the diff)

In addition, the code handling Values/Deletion was basically identical.
This patch unifies the code. Finally, this patch also adds testing for
merge_helper.
