• 2437: lowercase when looking up self referential foreign key columns fixes: dolthub/dolt#7700
• 2436: Making @@server_id default value match MySQL
• 2434: Fixing the default value for the binlog_checksum system variable Small change to make the default value of the global binlog_checksum system variable match MySQL's default value (i.e. "CRC32").
• 2433: NULL to nil The SHOW FIELDS/COLUMNS FROM <table> query would return the string "NULL" for Default column rather than nil. This mattered for Knex, which relied on it being NULL and not "NULL". fixes: dolthub/dolt#7692
• 2432: support Threads_connected and Threads_running status variables This PR adds support for Threads_connected and Threads_running status variables. Additionally, the local enginetest are flaking consistently in dolt ci, so those have been removed; we have handler tests for com_delete, com_insert, and com_update anyway. Related: dolthub/dolt#7646
• 2431: Setting Innodb_buffer_pool_pages_total to 1, to avoid an issue with Datadog's collector Datadog's metric collector errors out with a divide by zero error if the Innodb_buffer_pool_pages_total status variable is 0; changing it to 1 avoids this and allows the agent to collect metrics from Dolt.
• 2430: have status variables use go routines This PR changes Status Variables to update through go routines, to avoid slowing down query execution due to the mutexes present.
• 2429: server trace time includes parsing
• 2427: support Com_delete, Com_insert, Com_update status variables related: dolthub/dolt#7646
• 2426: use @@session.collation_server during create database ... This PR makes it so create database ... actually reads the @@session.collation_server variable. Additionally, this ensures that settings @@character_set_server sets @@collation_server and vice versa. Interestingly, it seems like MySQL actually ignores the global scope of these system variables, and reads the session scope instead. fixes dolthub/dolt#7651
• 2423: Adding test for preparing time.Time types This PR adds tests for using time.Time, some tests have to be skipped because we don't support Timespan correctly. companion pr: dolthub/vitess#327 dolthub/vitess#328 test for dolthub/dolt#7665
• 2422: Support Questions status variable This PR adds logic to update status variable Questions. This only works in the server context, probably doesn't through dolt sql cli. dolthub/dolt#7646
• 2421: [stats] costed index scan perf Histogram copying is expensive. Instead pass and mutate references. We have to use a different struct type to load stats from JSON in order to support histogram interface generalization. related Dolt-side: dolthub/dolt#7666
• 2420: support case-insensitive LIKE for show status/variables MySQL stores session and global variables in a performance_schema database, and these tables have a case-insensitive collation on the variable names. This PR emulates that behavior by hard coding the collation the schemas for ShowStatus and ShowVariables nodes.
• 2419: Bug fix: Allow JSON scalar comparison between int64 and float64
