myisam tables Queries following TRUNCATE of partitioned MyISAM table may crash server if myisam_use_mmap is true. Internally this is MyISAM bug, but limited to partitioned tables, because MyISAM doesn't use ::delete_all_rows() method for TRUNCATE, but goes via table recreate instead. MyISAM didn't properly fall back to non-mmaped I/O after mmap() failure. Was not repeatable on linux before, likely because (quote from man mmap): SUSv3 specifies that mmap() should fail if length is 0. However, in kernels before 2.6.12, mmap() succeeded in this case: no mapping was created and the call returned addr. Since kernel 2.6.12, mmap() fails with the error EINVAL for this case. |
