15f4ddfd8a support for --critical-load-interval-millis 
this optional flag gives --critical-load a second chance. When configured to positive value, meeting with critical-load spawns a timer. When this timer expires a second check for critical-load is made; if still met, gh-ost bails out.
By default the interval is zero, in which case gh-ost bails out immediately on meeting critical load.

1f65473e69 support for --discard-foreign-keys 
This flag makes migration silently and happily discard any existing foreign keys on migrated table. This is useful for intentional dropping of foreign keys, as gh-ost does not otherwise have support for foreign key migration.
At some time in the future gh-ost may support foreign key migration, at which time this flag will be removed

51f0c0d957 fix arg conversion in BuildDMLUpdateQuery 2016-09-27 13:08:31 +02:00
Paulo Bittencourt
2f80c9d424 Used the source column definition to fetch and convert insert values 
When processing binlog insert statements, we want to use `sharedColumns`
to decide which values to fetch and convert from the insert DML event.

We only want to  `mappedShareColumns` to define the column names in the
`replace into ...` statement.

791d963ea0 Character set recognition and manipulation 
- Identifying textual characters sets; converting into specific type when applying dml events
- Refactored `ColumnsList`: introducing `Column` type
- Refactored `unsigned` handling, as part of `Column`
- `Column` type supports `convertArg()`: converting value of argument according to column data type
- DB URI attempts `utf8mb4,utf8,latin1` charsets in that order (first one to be recognized wins)
- Local tests filter by pattern
- Local tests append table schema on failure
- Local tests do not have postpone flag file
- Added character set local tests: `utf8`, `utf8mb4`, `latin1`

- `--max-lag-millis` is at least `100ms`
- `--heartbeat-interval-millis` introduced; defaults `500ms`, can range `100ms` - `1s`
- Control replicas lag calculated asynchronously to throttle test
  - aggressive when `max-lag-millis < 1000` and when `replication-lag-query` is given

d3422bd19a Give more info about foreign keys 
This helps when the table itself doesn't have foreign keys defined but if there are other tables with foreign keys pointing to the table on which gh-ost runs.

This gives INFO messages for each FK. Note that it now informs the user about `payment` being involved.
