January 27, 2020

This page lists additions and changes in v19.1.7 since v19.1.6.


Cockroach Labs has discovered a bug relating to incremental backups, for CockroachDB v19.1.0 - v19.1.11. If a backup coincides with an in-progress index creation (backfill), RESTORE, or IMPORT, it is possible that a subsequent incremental backup will not include all of the indexed, restored or imported data.

For more information, including other affected versions, see Technical Advisory 63162.

Bug fixes

  • Some incorrect issue links referenced to by error hints have been corrected. #43234
  • Prevented rare cases of infinite looping on database files written with a CockroachDB version earlier than v2.1.9. #43253
  • Changefeeds now emit backfill row updates for a dropped column when the table descriptor drops that column. #43037
  • EXPLAIN can now be used with statements that use AS OF SYSTEM TIME. #43305
  • Fixed a bug that caused some jobs to be left indefinitely in a pending state and never run. #43416
  • Migrating the privileges on the system.lease table no longer creates a deadlock during a cluster upgrade. #43508
  • Fixed a bug in the parsing logic for server.host_based_authentication.configuration, where both single-character strings and quoted strings containing spaces and separated by commas were not properly parsed. This would cause rules for usernames consisting of a single character or usernames containing spaces to apply improperly. #43812
  • A SQL row write that is re-issued after already succeeding no longer throws a duplicate key error when the previous write in its transaction deleted the row. #43942
  • Fixed a changefeed bug where a resolved timestamp might be published before all events that precede it have been published in the presence of a range merge. #44082
  • Converted a panic when using collated strings to an error. #44119

Performance improvements

  • A transaction running into multiple intents from an abandoned conflicting transaction now cleans them up more efficiently. #43589
