Release highlights

Java 17

The language level used for Gerrit source code stays on Java 11, however, Gerrit is built and distributed for Java 17, which is the recommended JVM version for running it in production.

New stream events

batch-refupdate

Gerrit notifies all the refs of a single batch-refupdate as a single stream event JSON payload Issue 40015567. The new batch-ref-updated event is controlled by configuration and can be switched off for backward compatibility with legacy CI/CD systems.

ref-update for draft-comments

Gerrit generates the ref-update event for all the additions and removals of draft comments in the All-Users project (Change 382819). This is needed for replicating the All-Users project across sites, thanks to the replication plugins being notified of the updates.

Due to the nature of drafts, on busy installations the amount of ref-updated events created on draft operations could be high, possibly having an impact on performance.

For this reason this is disabled by default, you can enable it by configuring event.stream-events.enableDraftCommentEvents=true in gerrit.config Change 385714

New limits

There are new limit definitions which can be used to protect Gerrit from improper client activity.

  • change.topicLimit: defines the maximum number of changes in the same topic (Change 381055.

  • change.maxFileSizeDownload: prevents memory overload caused by clients downloading large files from REST-API (Change 381595).

  • change.maxFileSizeDiff: prevents memory overload caused by rendering large files diffs in a browser.

New diff3 view

A new change.diff3ConflictView option allows to enable a richer diff3 rendering of changes with conflict markers (Change 382894).

Attention-set improvements

Gerrit can return changes to the original attention set assignment if any of the new assignees do not provide feedback within a specific time (Issue 40015204). The behaviour is controlled by two new settings, attentionSet.readdAfter and attentionSet.readdMessage.

Indexing improvements

Allow to limit the queries that do not specify a default limit and also can now reindex changes with an asynchronous process when a change is updated from the UI, controlled by the index.indexChangesAsync.

The new option yields a much more responsive user-experience by releasing UI elements without waiting for the backend reindex execution to complete.

Account deletion

Users can now delete their own account, making it possible to be forgotten by the Gerrit Code Review platform. Please note that existing commits in the projects will stay and the account’s e-mail stored in Git commits will be preserved beyond account deletion.

User Suggested Edits

User Suggested Edits are an easy and fast way for reviewers to suggest code changes that can be easily applied by the change owner. They were introduced in 3.7.2 as an experimental feature, disabled by default. With Gerrit 3.9, this feature is no longer experimental and User Suggested Edits are now enabled by default.

Plugin development

Custom key/value pairs stored in NoteDb

Plugins may store additional string key/value pairs to change notes in NoteDb.

Change 372694 Added APIs to set/get custom keyed-value change metadata

Cross-plugin communication and dependency

Plugins can communicate and declare dependencies to other plugins thanks to the introduction of Gerrit-ApiModule Guice modules in plugin manifest (Issue 292114807).

Lookup changes by change number

Change 394440 flagged the API Changes.id(int) as deprecated to prevent using it from plugins and fail to locate changes imported from Gerrit servers with a different server-id.

Important notes

Upgrade from Gerrit v3.9.0 (defective release)

The release of Gerrit v3.9.0 has been impacted by the bad merge of Change 394445 due to the “implicit merge on moved changes issue” that has pulled 64 unwanted commits from the master branch. As a consequence, the version has been declared defective and withdrawn.

The upgrade from 3.9.0 to the following 3.9.* patch-releases needs to follow the instructions of the “Offline upgrade” because it contains an incompatible Lucene Engine that won’t be able to read the legacy index data.

Schema and index changes

This release doesn’t contain schema changes.

The accounts index version has been increased to version 13. The changes index version has been increased to version 84. The groups index version has been increased to version 10. The projects index version has been increased to version 8.

Online index schema upgrade from 3.7/3.8

By default, if you’re upgrading from 3.7/3.8, the index is automatically rebuilt upon Gerrit startup after the upgrade.

If you’re upgrading from 3.6 or an earlier version, you must use the Offline upgrade steps below.

Offline upgrade

  1. Download the new gerrit.war
  2. Stop Gerrit
  3. Ensure all installed plugins are compatible with the new API
  4. Run init
  java -jar gerrit.war init -d site_path --batch
  1. Reindex

  • If you are upgrading from a 3.7/3.8 versions you don’t need to run reindex (see Online index schema upgrade from 3.7/3.8 above). If you still want to you will need to run reindex:

      java -jar gerrit.war reindex -d site_path

  • If you are upgrading from a 3.6 or an earlier version, you must run a reindex of all indexes:

     java -jar gerrit.war reindex -d site_path

See the reindex program for other options.

  1. Start Gerrit

Online upgrade with zero-downtime

Gerrit v3.9.x supports zero-downtime upgrade from Gerrit v3.7 or later when configured using a high-availability configuration , and the Git repositories are stored in a shared filesystem such as NFS or similar.

During the zero-downtime upgrade, Gerrit end-users would not notice any outage or service disruption. They will be able to perform any read/write Gerrit operation on the GUI or using any API.

The zero-downtime upgrade consists of the following steps:

  1. Have Gerrit servers running v3.7 or later, in high-availability configuration, healthy and able to handle the incoming traffic properly.
  2. Set gerrit.experimentalRollingUpgrade to true in gerrit.config on both Gerrit primaries.
  3. Set one of the Gerrit servers to unhealthy.
  4. Shutdown the Gerrit server, update gerrit.war and plugins to v3.9.x and start Gerrit again.
  5. Verify that the Gerrit server is working properly (e.g. run automated smoke tests) and then make it healthy again.
  6. Wait for the Gerrit server to start serving traffic normally.
  7. Repeat steps 3. to 6. for all the other Gerrit servers.
  8. Remove gerrit.experimentalRollingUpgrade from gerrit.config on both Gerrit primaries.

Downgrade

Downgrade to any Gerrit v3.7/v3.8 release is possible, but requires the following manual steps:

  1. Shutdown all migrated Gerrit servers
  2. Update the gerrit.war and plugins to the previous v3.7/v3.8 version
  3. Run offline change reindexing using the previous gerrit.war version
  java -jar gerrit.war init -d site_path --batch
  java -jar gerrit.war reindex -d site_path
  1. Startup Gerrit server

Native packaging

Breaking changes

  • Change 369234 Return 400 BAD_REQUEST when a reviewer cannot be added by email

    When trying to add a user that cannot be added as a reviewer on a change, the API was returning a 200 Status Code with an error message.

  • Change 379475 Don’t call Java gc explicitly, remove –gc option from show-caches ssh command and REST API /config/server/summary

  • Change 378638 Remove change.stars field from ChangeInfo

    Remove the stars field from the ChangeInfo response. You should check whether you were relying on this field when using any REST endpoint returning ChangeInfo.

  • Change 373780 removed all performance/operations/* metrics because of the performance issues introduced (details)

  • Change 371198 Add option to populate ‘starred’ field for change queries

    star option can must now be provided to include the starred field in ChangeInfo, which indicates if the change is starred by the current user or not.

  • Change 387435 refreshAfterWrite and maxAge settings in gerrit config are now honored for both persistent and in-memory caches.

    Previously these settings were erroneously ignored for persistent caches. If you rely on them for persistent caches you should be aware they will be honoured now.

  • Change 379154 New patch sets will prefer the previous patch set’s committer email

    If one of the user’s secondary emails was used as the committer email in previous patchset, continue using it instead of preferred email.

  • Change 390986 Update mockito to 5.6.0 and bytebuddy to 1.14.9

    Mockito framework was upgraded from 3.3.3 to 5.6.0, hence if you have some custom plugins your test code might require some minor refactoring. Please refer to the mockito documentation and the release notes

Other changes

  • Change 394435: Support listing of patch-set files also for imported changes from other Gerrit server-ids

    Gerrit supports tracing requests that match a configured trace configuration. With this change we add a new parameter to the tracing configuration that allows matching requests by a header. E.g. this allows matching requests that are sent with a certain user agent (e.g. headerPattern = User-Agent=foo-.*).

  • Change 392518 Change .scl files to be highlighted as python

  • Change 392175 Reviewer’s votes are not restored back after the reviewer is deleted and added back

    When a reviewer votes for the patchset and then the reviewer is removed, Gerrit removes votes from this reviewer too. However if the reviewer is added back (to the same patchset) previous votes are restored back.

    This change ensures that after a reviewer is deleted, all votes from this reviewer are permanently removed.

  • Change 390897 Option to skip projects during change reindexing

    Introduce index.excludeProjectFromChangeReindex: A list of projects that will be excluded from reindexing. This can be used to exclude projects which are expensive to reindex to prioritize the other projects.

Other dependency changes

Other core changes

  • Change 327739 Update Java language level to Java 17 per default

Bugfix releases

3.9.4

  • Security Fixes

    • Issue 321784734: Fix endless loop when using “is:watched” in project watches.

      Previous setting up email notification with is:watched predicate would create an infinite loop that would take a CPU offline.

  • Breaking changes

    • Change 416278: Validate and reject SSH keys with invalid or mismatched algorithm

      Verify that the OpenSSH key algorithm matches the one associated with the public key. Throw a new specific InvalidKeyAlgorithmException if the two algorithms do not match.

      Make SshKeyCacheImpl tolerant to existing keys stored in the accounts’ profile, otherwise Gerrit may start flagging keys that have been previously stored as invalid, resulting in random authentication failures by existing users.

      Existing invalid keys are reported in the error_log with the associated exceptions and automatically fixed, removing the invalid key from the accounts profile and adjusting the key algorithm with the one associated with the public key.

  • Breaking changes

    • Change 404018: Add option to populate ‘starred’ field for change queries.

      A star option must now be provided to include the starred field in ChangeInfo, which indicates if the change is starred by the current user or not.

  • New Features

    • Change 406237: Add metrics for git/upload-pack/bitmap_index_misses_count and a separate one for missing bitmap indexes.

      JGit packer tracks the number of times that an object was not found in the bitmap index or if the bitmap index was completely missing. Added the git/upload-pack/bitmap_index_misses_count for being used in performance graphs, while the git/upload-pack/no_bitmap_index should be more suitable for alerts.

    • Change 406004: Add timer for git/upload-pack/phase_searching_for_* phases.

      Add metrics for the “Finding sources” phase, which is critical for an optimal Git/HTTP performance.

    • Change 402497: Introduce configurable shutdown timeout

      Added container.shutdownTimeout to configure the maximum time (in seconds) to wait before terminating Gerrit.

    • Change 404718: Add timer for git/upload-pack/phase_negotiating.

      Added the git/upload-pack/phase_negotiating so that the Gerrit admin can graph how these are performing and spot any potential issues. JGit packer tracks time spent in the negotiation phase. This statistic was only exposed in the sshd_log and is not available when the client uses Git/HTTP.

    • Change 393037: Bazel: Add support for BuildBuddy RBE provider.

      BuildBuddy provides an open-core suite of enterprise features for Bazel.

  • Bug Fixes

    Fixes plugin load failure when multiple plugins were declaring ApiModules for cross communication.

    Fixes potential NullPointerException when ignoreSelfApproval magic label is used.

    • Issue 314113030: Fail the change reindex operation upon StorageException(s).

      Allows some of the indexing operations to fail, so that if a change indexing throws a StorageException, so that the change does not disappear from the index.

    • Change 395741: Fix event parse exception when changing repository HEAD.

      Explicitly registered a type and class for ProjectHeadUpdatedEvent in EventType in order to successfully deserialize events.

    • Issue 318745940: Fix serverId in identity parsing for imported human comments.

      Remapping of account-ids correctly adapts the comment’s author account-ids and serverId fixing the inconsistent identity of the comments.

    • Change 400997 Reduce email spam, by not notifying existing reviewers when new ones are added

    • Issue 318079520 Fix comments rendering with imported changes

      Fixes a bug when comments posted on changes imported from another Gerrit instance were not rendered in the UI.

    • Issue 40014889 Fixed WIP changes always showing Merge Conflict in searches

      Fixes the work-in-progress changes always shown as having a merge conflict when change.mergeabilityComputationBehaviour was set to value other than NEVER.

    • Issue 312895375 Fix comment directly link pointing to a change imported from other Gerrit server-ids

      Fixes direct links to a comment on a change imported from another Gerrit instance returning HTTP status 404.

    • Change 404937: Fix copyable change links when base URL has a path.

      Removed extra base URL prefix in gr-copy-links. The links are crafted from createChangeUrl which already returns an URL with the base URL.

    • Issue 311925527: Fix canonical web url binding in Git over HTTP.

      Fix a problem encountered in the virtualhost plugin, where despite proper configuration for tenant canonical web URL, the git push output would use the value of gerrit.canonicalWebUrl configuration option.
