Release highlights

Important notes

JCraft JSch client library is disabled per default

Deprecated JCraft JSch client library is replaced with MINA SSHD client library per default. There is still option to switch to using JCraft JSch client library. Support for JCraft JSch will be removed in the next gerrit release.

Default support for Java 11

The java language level is now set to Java 11 by default for Gerrit.

  • Issue 13494; Generate a Java 11 Eclipse project by default

  • Update dev-{eclipse,intellij} development for Java 11.

Gerrit source code is still compatible with Java 8.

Schema changes

This release doesn't contain schema changes.

The changes index version has been increased to version 61, new change search operators were added: mergedafter and mergedbefore.

To run off-line reindexing of the changes (optional):

  java -jar gerrit.war reindex --index changes -d site_path

By default the changes index is automatically rebuilt upon the Gerrit startup after the upgrade.

Zero-downtime upgrade

Gerrit supports zero-downtime upgrade from Gerrit v3.3 when configured using a high-availability configuration, when the Git repositories are stored in a shared filesystem such as NFS or similar.

For upgrading with zero-downtime, you should enable the rolling upgrade migration in gerrit.config on both Gerrit servers by setting the gerrit.experimentalRollingUpgrade to true.

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 the Git protocol.

The zero-downtime upgrade consists of the following steps:

  1. Have Gerrit servers upgraded to v3.3 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 servers.
  3. Set the first Gerrit server unhealthy.
  4. Shutdown the first Gerrit server, upgrade to v3.4 and start Gerrit again.
  5. Verify that the first Gerrit server is working properly and then make it healthy again.
  6. Wait for the first Gerrit server to start serving traffic normally.
  7. Repeat steps 3. to 6. for the second Gerrit server.
  8. Remove gerrit.experimentalRollingUpgrade from gerrit.config on both Gerrit servers.

Downgrade

Downgrade to any Gerrit v3.3.x release is possible, but requires the following manual steps:

  1. Shutdown a migrated Gerrit v3.4.x server
  2. Run Gerrit v3.3.x init
  3. Startup Gerrit v3.3.x server

Breaking changes

is:mergeable predicate is disabled per default.

Computing is:mergeable has a O(N^2) runtime computation complexity depending on the number of open changes on a branch and on the size of the changes. Hence skip this computation per default to avoid the associated runtime effort.

Most Gerrit installation already disabled this feature and thus wouldn't need to change anything. Otherwise, to restore the previous behaviour this option: change.mergeabilityComputationBehavior should be changed to API_REF_UPDATED_AND_CHANGE_REINDEX.

HTML plugin support is removed

HTML plugins should be migrated to JavaScript plugins. This also implies Polymer 2 plugins wouldn't work any more. See also this announcement for more details.

These unused JavaScript Plugin API methods were removed:

  • plugin.annotationApi().setLayer(), plugin.annotationApi().enableToggleCheckbox()
  • plugin.changeMetadata().*
  • plugin.changeReply().send()
  • plugin.eventHelper().on(), plugin.eventHelper().captureClick(), plugin.eventHelper().captureTap()
  • plugin.project().*
  • plugin.settings().*
  • plugin.styles().*
  • plugin.theme().*
  • plugin.get(), plugin.post(), plugin.put(), plugin.delete(): Replaced by their counterparts in plugin.restApi().

ChangeAttributeFactory is removed

As noted in the v3.3 release notes, ChangeAttributeFactory has been removed.

Native packaging

New features

Checks UI

Gerrit now has a native UI for displaying run/result info from builds, tests, analyzers, etc. The data for this new Checks UI must be provided by JavaScript plugins using the Checks API. Checks information will be summarized by chips below the commit message. Detailed information is shown on a dedicated Checks tab next to the Files and Comments tabs.

Unresolved Comments ported to latest patchset

Unresolved comments that were left on older patchsets will now also be shown on newer patchsets. The backend provides two new endpoints ported_comments/ and ported_drafts/ for the UI to retrieve the data and for showing the comments in the correct position.

Comment Chips and Context

Comment state (resolved, unresolved, draft) is summarized by chips below the commit message. The Comments Tab and the Change Log will not just show the comment thread, but also the snippet of code (where the comment was made) as context.

Bugfix releases

3.4.8

  • Performance Improvements

    • Change 350236 Optimized change visibilty checking when the project is hidden

      Looping over every change when the whole project isn‘t readable is a waste of CPU. It’s a bigger waste to fetch all the change data in the first place.

  • Native packaging

    • GerritForge RPM repository updated for arm64 architecture

      GerritForge RPM v1.4 has been released, including the native packages for arm64 architecutre.

    • DockerHub images for arm64 architecture

      DockerHub Gerrit images include images for arm64 architecture.

  • Bug Fixes

    • Issue 16404: Fix disabled caches when reading all keys at once

      When disabling some caches like git_file_diff the fetching of the keys was causing a ClassCastException and the associated Gerrit functionality was broken. This change fixes the bulk loading of all keys and allows to disable any of the Gerrit caches without regressions.

    • Change 350414 Fix index rewriter to rewrite all Or/AndPredicates. AndSource chooses right source more often

3.4.7 - Not recommended

  • Known issues

    • Issue 16404: Fix disabled caches when reading all keys at once
  • New features

    • Issue 16322: Limit the number of changes that can be submitted together

      When chaining changes together, the sequence of commits to navigate was previously unbound, causing the potential operations explosion. The explosion could have also been accidental and caused by the push of a change with a non-existent branch, which would have resulted in the full scan of the repository for changes. Introduce a new Gerrit configuration change.maxSubmittableAtOnce with a safe default of 1024, which would allow any use case that would have also worked before this change.

    • Change 347496: Enable project_list cache warmer when cache.project_list.maxAge is set

    • Change 341454: GitwebServlet: Retrieve git path from FileRepository so that it can be used with multi-site and cached-refdb modules

  • Performance Fixes

    • Issue 16379: Remove key locking for disabled caches

      This change also makes the memoryLimit behaviour consistent with the diskLimit set to zero means disabling the implementation of the cache.

    • Change 349895: Add AndCardinalPredicate and OrCardinalPredicate

      Before this change, IndexSource derived cardinality from predicate which implement HasCardinality. Since AndPredicate and OrPredicate does not return cardinality, IndexSource defaults to 10 when query comprises more than one predicate. Due to this behavior, AndSource chooses IndexSource almost always when query contains more than one index predicate. This helps AndSource to choose the right source more often.

    • Change 347956: Introduce possibility to define the cardinality so that AndSource predicate can work more efficiently

      Before this change, cardinality of the IndexSource was always set to 10. This makes AndSource to choose IndexSource over other sources most of the time. Add a HasCardinality interface which can be used by all the predicates which implement IndexPredicate to set a cardinality. This helps AndSource to choose the right datasource.

    • Change 349355: Cache repository locations in LocalDiskRepositoryManager

      Obtaining the actual location of a repository using base-path and project name can be slow as it involves some guessing to locate the repository. Cache the locations once they are obtained to avoid repeated work, thereby improving performance when opening repositories.

    • Change 347955: Consider cardinality while choosing the data source for AndSource predicate

      Before this change, AndSource considered cost to choose a datasource. Ideally cost should be used to determine which predicate to run #match() against first, so that queries are faster. Cardinality should be used to determine which datasource to be picked so that there are fewer changes to process. Consider cardinality of the datasource to choose the source and use cost when cardinality is same.

  • Bug Fixes

    • Change 350014: Do not set cherryPickOf on RevertSubmission

      The RevertSubmission internally uses CherryPickChange operation. It creates the ‘normal’ revert for the first change in the relation chain, for each subsequent change it creates a revert commit that is then cherry-picked. This cherry-pick is not a cherry-pick of the reverted change. This is a cherry-pick of the revert commit of the original change. This change fixes the bug in the logic that sets cherryPickOf to the original (reverted) change, using the CherryPickChange operation.

    • Change 349894: Don't always rewrite And/OrPredicate to And/OrSource

      Before this change OrPredicate was always rewritten to OrSource. This is not the right thing to do as OrSource#read() will eventually fail when there is at least one non-datasource child. Since Change 347955, AndSource picks a source which has the lowest cardinality which makes the OrSource#read() failures more visible. Rewrite OrPredicate to OrSource only when all the children in the predicate are DataSources.

    • Change 348715; Clarify that a restart is needed before changes to email templates take effect

    • Issue 16182: Reintroduce the Change-Id footer in change screen

      This change reintroduce the Change-Id footer below the commit message on the Gerrit UI.

    • Issue 10168: Fix HTTP 404 when browsing tags on Gitweb

      The Gitweb links to tags have been broken in v2.14.10 onwards. Gitweb supports the ‘a=tags’ rendering action for annotated tags only, returning 404 for all lightweight tags. Use the generic ‘a=shortlog’ for Gitweb links to tags which would work for both annotated and lightweight ones.

    • Change 347495: Fix for IllegalStateException during the Gerrit start when cache.projects.refreshAfterWrite is set to true and prolog rules are used

    • Issue 15997: Make DelegateRepository#delegate() method public to allow plugins/modules to access it

3.4.6

  • Security Fixes

    • Issue 16054: Fix confidentiality leak by users with create ref permission using the create branch REST-API

  • Breaking changes

    • Issue 15941: Fix SSH queries to not show commit-message unless --commit-message is provided

      This issue has existed for several years and should be considered breaking as users might expect commit message to be included by default in SSH query results. Obtaining the commit message is a costly operation as the commit data has to be loaded. So, showing it even when --commit-message is not provided degrades the performance of SSH queries.

    • Change 344300: Add missing return values in MetricMaker's newCallbackMetric and newConstantMetric

      When new callback and constant metrics were created the RegistrationHandle was not returned, making impossible to de-register them. The method signature is now aligned, however, all plugins, including the core ones, that were registering callback or constant metrics would need to be rebuilt from source or downloaded from the latest build on Gerrit-CI.

      The gerrit review command was not able to find the commit with branch option; ensure “refs/heads/” prefix is present for branch option.

    • Issue 16106: Fix label operator to work with external groups, which never worked before since its addition in v2.10.

    • Change 331762: Cache permission filtering for All-Projects, allowing a faster ACL evaluation to any refs.

    • Change 343694: Improve performance of queries that check the visibility of changes wrt a non-current user

    • Change 346254: Fix change queries evaluation of AND terms to run match on predicate whose cost is least

      Sort the change queries predicates in AND based on cost and cardinality, which was broken since Change 79391.

      WARNING: queries containing predicates with poorly defined costs or cardinalities could perform worse now.

  • Breaking changes

    • Change 323855 Change 324115: ProjectCache#evict no longer triggers a reindex.

      During offline project reindexing evict() was triggering a duplicate reindex on the project when we only wanted to evict the project cache entry. This same issue occurred with the HA plugin and could be/been present in other plugins.

      If you have relied on a reindex being done on evict() you need to use evictAndReindex() instead. This behavior is now consistent with other evict() methods in Gerrit.
