Revision 71f5bcb73012f38fe3499089bd5d332e07d32c40 authored by Andrew Kryczka on 23 June 2017, 02:30:39 UTC, committed by Facebook Github Bot on 23 June 2017, 02:41:50 UTC
Summary: Some users want to prevent rocksdb from entering read-only mode in certain error cases. This diff gives them a callback, `OnBackgroundError`, that they can use to achieve it. - call `OnBackgroundError` every time we consider setting `bg_error_`. Use its result to assign `bg_error_` but not to change the function's return status. - classified calls using `BackgroundErrorReason` to give the callback some info about where the error happened - renamed `ParanoidCheck` to something more specific so we can provide a clear `BackgroundErrorReason` - unit tests for the most common cases: flush or compaction errors Closes https://github.com/facebook/rocksdb/pull/2477 Differential Revision: D5300190 Pulled By: ajkr fbshipit-source-id: a0ea4564249719b83428e3f4c6ca2c49e366e9b3
