October 12, 2020

This page lists additions and changes in v19.2.11 since v19.2.10.

  • For a comprehensive summary of features in v19.2, see the v19.2 GA release notes.
  • To upgrade to the latest production release of CockroachDB, see this article.
Warning:

A denial-of-service (DoS) vulnerability is present in CockroachDB v19.2.0 - v19.2.11 due to a bug in protobuf. This is resolved in CockroachDB v19.2.12 and later releases. When upgrading is not an option, users should audit their network configuration to verify that the CockroachDB HTTP port is not available to untrusted clients. We recommend blocking the HTTP port behind a firewall.

For more information, including other affected versions, see Technical Advisory 58932.

Warning:

Cockroach Labs has discovered a bug relating to incremental backups, for CockroachDB v19.2.0 - v19.2.12. 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.

Users are advised to upgrade to v20.1.15 or v20.2.8 or later, which includes resolutions.

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

Bug fixes

  • The Cluster Node Map and the Debug Page that lists cluster localities are now available again to non-admin users. This fixes a bug introduced in v19.2.3. #53332
  • Fixed a bug that could cause backfills to fail with a vague TransactionStatus error as they are completing. #53765
  • Fixed a bug that could cause CockroachDB to crash when evaluating queries with window functions with the GROUPS mode of framing when OFFSET FOLLOWING boundary was used and when the offset was a very large value such that it could result in an integer overflow. #53758
  • Fixed a bug that could cause CockroachDB to crash when using a RANGE-mode window function with an offset in some cases (e.g, OVER (PARTITION BY b ORDER BY a RANGE 1 PRECEDING). #54074
  • Adding a NOT NULL constraint no longer fails with the error check ... does not exist. #54290

  • Fixed a rare bug that could lead to index backfills failing on transaction restarts. #54860
