Is this an intended change? I am seeing a crash associated with UNIV_SYNC_DEBUG (after removing that undef). So, should this be kept or removed?

This bug being unfixed allows UNIV_SYNC_DEBUG to bitrot, see bug 71092.

Fixed as of 5.6.16, 5.7.4, and here's the changelog entry: "UNIV_SYNC_DEBUG", which was disabled in "univ.i" with the fix for Bug#16720368, is now enabled. Thank you for the bug report.

Thank you for the contribution!

Description: univ.i has this new line in 5.6.12 compared to 5.6.11: #undef UNIV_SYNC_DEBUG Line 174. Bzr annotate points to [1], whose commit message does not mention this rather big change, nor the commit itself looks like it would be related to locking in any way. Is it an unintended change that should be reverted?

This is unchanged before and after this patch. What this fix addresses is the case when crash recovery is needed. Previously, InnoDB could load a corrupted tablespace file. buf_page_is_corrupted(): Add the parameter check_lsn. fil_check_first_page(): New function, to perform a consistency check on the first page of a file. This can be overridden by setting innodb_force_recovery. fil_read_first_page(), fil_open_single_table_tablespace(), fil_load_single_table_tablespace(): Invoke fil_check_first_page(). open_or_create_data_files(): Check the status of fil_open_single_table_tablespace(). rb#2352 approved by Jimmy Yang How to repeat: Open univ.i, search for UNIV_SYNC_DEBUG Suggested fix: Remove the #undef.
