Bug Reportmysql_error.log wrote:{YYYY-mm-dd HH:ii:ss} 8012 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace {database name}/{database table name} uses space ID: {#} at filepath: .\{database name}\{database table name}.ibd. Cannot open tablespace mysql/innodb_index_stats which uses space ID: {#} at filepath: .\mysql\innodb_index_stats.ibd
InnoDB: Error: could not open single-table tablespace file .\mysql\innodb_index_stats.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.
Reproducible TestcaseNone yet.
Reports say that this issue occurs after a MySQL restart, but i can't reproduce the issue yet.
Maybe this issue just occurs if XAMPP gets upgraded and not with fresh installations.
If someone can report a working reproducible testcase, let me know.
Affected XAMPP versionsAll XAMPP versions containing MySQL 5.6.X
Solutions / Workarounds- using XAMPP 1.8.2-1 (MySQL 5.5.32)
or - deleting the \xampp\mysql\data\ibdata1 file (data loss of all InnoDB Databases !!!)
