8f02ab0fed check the slave status when find recursive find the master, so support if the dba using reset slave instead of reset slave all. 2016-12-05 19:42:16 +08:00

bf92eec214 validating table structure on applier and migrator

- or else bailing out

62b8a897e3 Retries, better visibility, documentation
- Rowcopy time is bounded by copy end-time
- Retries are configurable via `--default-retries` (default: `60`)
- `migrator` notes the hostname
- `applier` and `inspector` note `impliedKey` (`@@hostname` and `@@port`)
- Added lots of code comments
- Adding documentation for "triggerless design"

9b54d0208f - Handling gomysql.replication connection timeouts: reconnecting on last known position
- `printStatus()` takes ETA into account
- More info around `master_pos_wait()`

1e10f1f29e Solved various race conditions:
- Operation would terminate after events lock noticed but before applying all events: race condition where the event would be captured asynchronously. The event is now handled sequentially with the DML events, hence now safe.
- Multiple rowcopy operations would still write to `rowCopyComplete` channel. This is still the case, but now we only wait for the first and then just flush (read and discard) any others, to avoid blocking
- Events DML listener is only added after table creation: the problem was that with very busy tables, the events func buffer would fill up, and the "tables-created" event would be blocked.
- `waitForEventsUpToLock()` unifies the waiting on all variants of complete-migration
- With `--test-on-replica`, now stopping replication "nicely", using `master_pos_wait()`
- With `--test-on-replica`, not throttling on replication after replication is stopped (duh)
- More debug output

07063a4181 - added throttle-control-replicas flag, a list of control replicas
- when `--test-on-replica`, the tested replica is implicitly a control replica
- added `replication-lag-query`, an alternate query to `SHOW SLAVE STATUS` to get replication lag
- throttling takes both the above into consideration
