7 Fresh Bugs in MySQL 8.0Roel Van de Paar
Friday afternoon is always ideal for a quick look at the early quality of MySQL 8.0! Last Friday, I did just that.
If you haven’t heard the news yet, MySQL 8.0 DMR is available for download on mysql.com!
Tools to the ready: pquery2, updated 8.0 compatible scripts in Percona-qa and some advanced regex to wade through the many cores generated by the test run. For those of you who know and use pquery-run.sh, this should mean a lot!
[09:41:50]  ====== TRIAL #39308 ======
In other words, almost 40K trials and 21.5K core dumps (or other significant issues) detected! This run had been churning away on a server for a number of days. On to the bug logging fun!
After reducing test cases, and filtering duplicates, we have the following seven bugs logged in upstream;
- Bug #83120 virtual void Field::store_timestamp(const timeval*): Assertion ‘false’ failed.
- Bug #83118 handle_fatal_signal (sig=11) in replace_user_table
- Bug #83117 Assertion MDL_checker::is_read_locked(m_thd, *object)’ failed.
- Bug #83115 Assertion ‘maybe_null’ failed. handle_fatal_signal in tem_func_concat::val_str
- Bug #83114 Assertion `strlen(db_name) <= (64*3) && strlen(table_name) <= (64*3)’ failed.
- Bug #83113 SIGKILL myself on DROP TABLE
- Bug #83112 handle_fatal_signal (sig=11) in sp_get_flags_for_command
My first impressions?
MySQL 8.0 DMR is a reasonably solid release for a first iteration.
It seems our friends at upstream are on an excellent path to making MySQL 8.0 another rock-solid release. Chapeau!
