Removal of GWT UI
The GWT UI is removed and PolyGerrit is now the only UI.
Removal of ReviewDb
The database backend for changes, accounts, groups and projects (“ReviewDb”) is removed and this metadata is now stored in git (“NoteDb”).
A database is still needed for account patch reviews, which stores the ‘reviewed’ flag for files in a review per user. The default backend is H2, but MySQL, PostgreSQL and MariaDb are also supported. See the documentation for details.
It is also possible for plugins to provide another backend by implementing the AccountPatchReviewStore
interface.
New quota enforcer extension point.
Issue 4040: Support for signed push with GPG subkeys.
New core plugins: delete-project
, gitiles
, plugin-manager
, and webhooks
.
This release contains schema changes. To upgrade:
java -jar gerrit.war init -d site_path
The changes index version has been increased. 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.
The gerrit.disableReverseDnsLookup
option with default value false is replaced by gerrit.enableReverseDnsLookp
also with default value false. This means that reverse DNS lookup is now disabled by default.
A warning dialog will be displayed to the user to confirm this on submission using the UI. When submitted via push, this warning will not be shown. Already merged changes cannot be marked private any longer.
urlAlias
configuration settings are removedThe URL rewriting feature introduced in 2.12 via the urlAlias
configuration was only supported in GWT, and thus removed with the 3.0 release.
See issue 8054 for details.
MessageOfTheDay
extension point is removedThe MessageOfTheDay
functionality was not ported to the PolyGerrit-UI and the MessageOfTheDay
extension point was removed with the 3.0.7 release. However, the JS API provides the banner
entrypoint for plugins to add messages to the UI. Plugins that were previously using the MessageOfTheDay
extension point have to be adapted accordingly.
New quota enforcer extension point.
Plugins may implement the QuotaEnforcer interface to enforce quotas.
Issue 4040: Support for signed push with GPG subkeys.
It is now possible to use a GPG subkey when pushing commits with signed push.
Issue 6053: Support for searching on mobile devices.
Issue 8535: Support for plugin config entries in the PolyGerrit UI.
Configuration entries defined by server-side plugins are now displayed in the UI.
Issue 10385: New Toggle Work In Progress state permission.
This allows for granting the “Toggle Work In Progress state” permission to arbitrary users. This permission controls who is able to flip the Work In Progress bit in addition to the three different groups that can do so already: change owner, server administrator and project owners.
Note that the option was included in 3.0.0 but only documented since 3.0.12.
New method to get UI top menus in the config API.
New configuration option change.api.excludeMergeableInChangeInfo
.
Computing mergeability of open changes becomes very expensive for hosts that have fast-moving branches and a lot of open changes. Setting this option to true
disables it.
New configuration option change.move
.
The change.move
option allows to disable the “Move Change” REST API.
Note that the option was included in 3.0.0 but only documented since 3.0.3.
New core plugins.
The delete-project
, gitiles
, plugin-manager
, and webhooks
plugins are now core plugins bundled with the release, and can be installed during site initialization.

command, or the configuration of the service for auto-start and the reboot of the machine.
Docker: auto-init the Gerrit site during first start of the container.
Simplify the configuration and management of Docker setups by automatically detecting if a $GERRIT_SITE/git/All-Projects.git
exists and, if it doesn't, invoke the Gerrit init step in batch mode.

Update Jetty to 9.4.33.v20201020.
Security Fixes
Issue 13621 CVE-2020-8919: Make PermissionBackend#ForRef
authoritative.
Fixes a misconception that leads to data being accessible through Gerrit APIs that should be locked down.
Gerrit had two components for determining if a Git ref is visible to a user: (Default)RefFilter
and PermissionBackend#ForRef
(e.g., RefControl
). The former was always capable of providing correct results for all refs. The latter only had logic to decide if a Git ref is visible according to the Gerrit READ
permissions. This includes all refs under refs/heads
as well as any other ref that isn't a database ref or a Git tag. This component was unaware of Git tags and notedb-related refs. Hence, when asked for a database reference such as refs/changes/xx/yyyyxx/meta
, the logic would allow access if the user has READ
permissions on any of the ref prefixes (such as the default “read refs/* Anonymous Users”).
That was problematic, because it bypassed documented behavior where a user should only have access to a change if he can see the destination ref. The same goes for other database references.
Issue 13514 CVE-2020-8920: Work around Gitiles bug on All-Users
visibility.
Gitiles has a special FilteredRepository
wrapper that allows carefully hiding refs based on the project's ACLs. There is however an optimization that skips the filtering in case a user has READ
permissions on every ACL pattern(s). When the target repository is All-Users
, the optimization turns into a security issue because it allows seeing all personal information associated with all accounts, i.e.:
This fix now blocks Gitiles or any other part of Gerrit to abuse this power when the target repository is All-Users
, where nobody can be authorized to skip the ACLs evaluation anyway.
This minor release has been withdrawn.
Breaking Changes
Elasticsearch: Support for EOL versions 6.6 and 6.7 is discontinued.
Issue 13184: Logging: --console-log
-flag of gerrit.war daemon
respects log.textLogging
and log.jsonLogging
options.
Change in the default behaviour of the --console-log
flag. Since log.textLogging
in the gerrit.config
is true
by default, using the --console-log
-flag now writes logs to the error_log
-file in addition to stderr by default. This can be avoided by setting log.textLogging = false
.
Bug Fixes
Issue 11706: ChangeEdits: Don't wrap Response.none()
in Response.ok()
.
Wrapping of edit message modification Response.none()
in Response.ok()
was erroneously added. Revert that part, as it broke the handling of that specific request.
Issue 13175: Fix gr-hovercard-behavior
under Firefox.
Issue 13328: Redirect GWT UI project dashboard links to Polygerrit endpoints.
Add a route to the Polygerrit UI router, to redirect such legacy GWT UI endpoints, so that existing menu links are handled without any modifications. Otherwise, switching from GWT to Polygerrit resulted in broken links to project dashboards. This fix also handles bookmarked links.
Issue 13350: Decode group id before using it to add cc-reviewers.
When a group is being suggested for cc-reviewer, its UUID gets encoded by Gerrit prior to rendering it. That had no impact on Gerrit internal groups, however external groups were affected. UUID prefixes contained encoded characters where they shouldn't have. Hitting the Reply button sent such encoded groups as is, leading to them not being found in Gerrit.
Decoding the URI before sending the group back to the UI fixes the issue.
Issue 13372: Remove obsolete GWT change-related screenshot.
The GWT UI is not included anymore in Gerrit from v3.0 onwards.
Replication Plugin Fixes
Fixed synopsis in replication start command documentation.
--url
is usable with --all
or projects and on its own. Update the usage to reflect this.
Issue 12769: Don't wait for pending events to process on startup.
Previously, on large Gerrit installations with many projects and/or many replication destinations, the replication plugin could take very long periods of time to startup. This was particularly a problem if the pending (persisted) event count was large as they all were rescheduled before the plugin finished initializing.
Change this behavior so that startup merely begins the process of scheduling the pending events, but does not wait for them to complete.
End-to-end Tests Improvements
Support an optional parent in the CreateProject
scenario.
Rely on a released version of gatling-git
in stable branch.
List of plugins with scenarios updated.
Documentation for Environment properties was refactored and augmented with replication_delay information, as the new CheckNewProjectReplica1
core scenario was added.
Issue 12208: Add presentation links to documentation.
Issue 13082: Add Eclipse support for Gatling tests.

Breaking Changes
Metrics: Cache disk stat metric computation is disabled by default
Calculation of the cache disks stat metrics for persistent caches is disabled by default because it is a very expensive operation that can block a thread for several minutes on larger installations.
Installations that still want to use this metric must explicitly enable it with the cache.enableDiskStatMetrics configuration option.

Issue 12527: Elasticsearch: Support for EOL versions v5.6 and v6.0 to v6.5 is discontinued
End-to-end Tests Improvements
Allow end-to-end tests to proportionally scale on their expected execution times.
A power_factor
environment property was added to the end-to-end tests core framework. Using that optional property, scenario steps can take some more (or less) time prior to expecting proper completion.
The way to set that property locally then depends on the target runtime environment, or SUT latency. The property may be used for either core or plugin scenarios.
FlushProjectsCache
related scenarios added to core (and the high-availability
plugin).
Support for relative runtime weights in scenarios.
Each scenario can now either weight like any other by default, or override that default with a greater weight value, compared to siblings that are lighter on execution times.
Beside core, make the high-availability
and multi-site
plugin scenarios reuse this.
Allow scenarios to create and delete Gerrit changes alongside projects.
Add the corresponding core support for an optional http
request body to every such GerritSimulation
. Either automate or allow environment properties to feed the related input test data.
Beside core, make the high-availability
and multi-site
plugin scenarios test changes that way. The latter currently has Issue 12693 as a known limitation.

Issue 12755: Block the removal of the Realm primary external ids.
It was possible to remove the email address associated with the primary id of a Realm, effectively resulting in the account being removed.
Isssue 12786: Fix wrong status returned when auth backend couldn't be reached.
The response 401 was returned when the auth backend could not be reached, instead of the response 503.
Issue 14242: Fix email token verification failures caused by non-URL-encoded characters.
Issue 11625: Avoid multiple notifications for existing reviewers.
Fix internal server error on parsing commit message during receive commits.
Add autocomplete="off"
to LDAP login form.
Some security tools will flag the absence of the autocomplete flag as a possible security issue, as it could allow for passwords to be saved and automatically filled in on shared computers.
Accept --ownedby
as an alias of --owned-by
in the groups REST API.
The option was incorrectly documented as --ownedBy
which resulted in an error “not a valid option” if anyone tried to use it.
The documentation is fixed, and --ownedby
is added as an alias so that it also works for anyone still referring to the old documentation.
Fix various misuses of the Flogger API causing exception details to be omitted in the log output.
Exceptions were not properly passed to the logger which would cause the details to be omitted, or in some cases the message “ERROR: UNUSED LOG ARGUMENTS” to be emitted.
Issue 12673: Fix emitting debug logs while running tests.

Issue 12385: Fix memory leak in gr-plugin-endpoints
.
Replication Plugin Fixes
Issue 12678: Fix missing replication Id in replication logs.
The migration to use Flogger in 2.16.17 caused a regression in the logging, where the replication Id was omitted from the logs. This is fixed by reverting back to slf4j logging for the replication log.
Issue 12719: Fix replication start --wait
to track in-flight collisions and to not fail.
Issue 12731: Don‘t lose state when there’s a pending push to the same ref.
If there was already a pending push (not an in-flight push) to the same endpoint, the start for the push would be dropped when adding the push to the Destination. This meant that a replication start --wait
command would never complete when one of its pushes was pending since its state would never receive the completion notification for that push.
Issue 11745: Fix firing pending “..all..” events on startup.
Issue 11760: Make persistent task keys stable.
Fix URL matching to match real URLs in addition to templated URLs.

Breaking Changes
The LogThreshold
annotation is removed.
The default log level for tests has been changed from DEBUG to INFO, and this annotation is no longer needed. It was originally introduced to allow classes to explicitly set their log level at level other than DEBUG.
Plugins that use this annotation must be adjusted.
New Features
Add support for Elasticsearch 7.6.x.
Include upload-pack
metrics in the sshd log.
In order to enable detailed performance and problem analysis, upload-pack
metrics are now included in the sshd log.
Add new configuration setting core.packedGitUseStrongRefs
.
When set to true, this option enables using strong references to reference packfile pages cached in the WindowCache. If this option is set Java gc can no longer flush the WindowCache to free memory if the used heap comes close to the maximum heap size. On the other hand this provides more predictable performance.
Add new configuration setting sendemail.denyrcpt
.
This new setting works alongside the existing sendemail.allowrcpt
, and allows to configure email addresses or domains that Gerrit may not send to.
Allow to format HTTP and SSH logs in JSON format.
When log.jsonLogging
is enabled, the HTTP and SSH logs are formatted as JSON, making it easier for them to be parsed. Note that the error log was already formatted in JSON when this option was enabled.
Add new metrics.

Security Fixes
Issue 12440: Fix the access-path for AbstractGitCommand subclasses.
The access path for the Receive.currentUser in the receive-pack command was wrongly set to SSH_COMMAND instead of to GIT. This allowed project owners to force-update a ref using git-over-SSH without having en explicit permission for that.
Bug Fixes
Fix size explosion of All-Users
caused by draft comment removal.
Modify draft comments generation so that, when removed, they to point to an empty parent.
Issue 11772: Cancel deprecation of change identifiers that was planned since 2.16.
Since 2.16 the documentation of change identifiers states that the identifiers other than <project>~<numericid>
are deprecated and will be removed in a future release. Since then the identifiers have still not been removed and there is no clear plan to do so.
It is likely that “deprecated” identifiers are still used in links in places where they can't be updated, for example in emails and forum posts. Due to this, and since continuing to support all of the types does not add any technical burden, ESC decided that the deprecation should be cancelled.
The change.api.allowedIdentifier
configuration setting is now obsolete and has been removed.
Issue 3340: Fix internal server errors when setting project access permission with bad regex.
Fix removal of stale metrics from the metrics registry.
Issue 12349: Fix time attribute of file entries in plugin artifacts.
Make assumption on number of query results explicit for change Id arguments.
When a change Id passed as argument was resolved to multiple changes, the first returned change was arbitrarily used. Now an error will be raised and logged.
download-commands plugin: Set SSH default port to 22.
Document dependency from account deactivator to autoUpdateAccountActiveStatus and log a warning if the account deactivation task is configured but will not be scheduled.
Fix handling of ambiguous name in visibleto

Issue 11953: Reduce log spam during tests by reducing the default log level to INFO.
The log level can now be explicitly set by the GERRIT_LOG_LEVEL
system variable.
The LogThreshold
annotation is removed.
New Features
Include request description in HTTP thread names.
The HTTP worker threads had generic names like HTTP-100
, HTTP-101
, etc. While we could conclude from the stack trace what this thread was doing, we missed some important information like repository name, user name, etc.
The HTTP threads now have descriptive names. For example, if there is an ongoing git-fetch operation we will see a thread named like: HTTP POST /a/myProject/git-upload-pack (johndoe from 10.87.75.169)
.
This makes the naming consistent with SSHD threads, which are named like: SSH git-upload-pack /myProject (johndoe)
.
New metrics for Jetty threadpool.
The new metrics are exposed under http/server/jetty/*
.
Utility program to delete zombie draft comment refs.
Deletion of draft comment refs was broken until 2.16.14, resulting in draft comment refs not getting deleted properly. Although it has been fixed, it's still possible that zombie refs exist from previous versions. The new site program DeleteZombieCommentsRefs
can be used to remove them.

extension point have to be adapted accordingly.
Bug Fixes
Issue 12246: Fix generation of duplicate Change-Id
s when creating a new change via REST.
The Change-Id
was computed from the commit content and the timestamp, which resulted in the possibility for two changes to get the same Change-Id
when two empty changes were created by REST at the same time.
The Change-Id

Fix internal server error when a change edit includes an invalid file path.
Invalid file paths are now rejected as ‘400 Bad Request’.
Don't check for conflicting refs when deleting a ref; improve performance of migration to schema 167.
The migration to schema 167 involves deletion of refs. The performance was poor for large installations (for example 30k user refs and 20k groups) because the ref deletion implementation was doing an unnecessary check for conflicting refs.

In some situations, draft comment refs were not properly deleted but left empty. This resulted in unused draft refs persisting in the All-Users
repository, polluting the namespace. Published draft comments as well as deleted draft comments were kept in the history of the draft ref, keeping them alive for GC, and causing a steady increase of repository size.
Use correct content type text/plain
instead of plain/text
in ‘Create SSH Key’ REST API.
Fix handling of interactive/batch users in the QoS filter.
For the git-over-http requests this filter didn't work properly because the basic authentication happened later in the filter chain and at the moment when the QoS filter was invoked the current user was not yet set.
Add project name to headers of outgoing change emails.
Fix and expand documentation of ref-update
and commit-received
hooks in the hooks plugin.

JGit Updates:
Upgrade JGit to 5.3.6.201910020505-r.

The change message and the message tag were inverted.
Fix commit message subject when updating project description by REST API.
The tense of the commit message subject was inconsistent with other similar messages.
Fix commit timestamp when updating project configurations.
For some REST API operations that update the project configuration, the commit that does the update on refs/meta/config
had the wrong timestamp. Rather than being the time of the actual commit, it was always the time of the server startup.
This was the case for the following operations:
Upgrade jackson-core to 2.10.0.
This version includes a fix for CVE-2019-12384.
Add more detailed debug logging when not sending an outgoing email.
There are several conditions that could cause sending of an outgoing email to be skipped. These are now logged at debug level.

Show submit button with tooltip when not allowed to submit.
The submit button was hidden when the user did not have permission to submit, or other conditions prevented submit (for example the change being WIP).
Don't send “GPG keys added” notification when no GPG keys were added.
A GPG key update can include both addition and removal of GPG keys. The notification email for addition of new keys was always sent, even if the update only removed keys.
Update email notifications on changing security related settings.
Email notifications are now sent when a GPG or SSH key is removed, and when the HTTP password is deleted or changed.
An email notification is now always sent when an SSH key is added to an account, even when it was added by an administrator.
These notifications allow to alert the user if their account is compromised and keys or password are altered by the attacker.
Remove explicit dependency on protobuf_java.
The protobuf_java library is now consumed from rules_closure.
Improve performance of migration of accounts to schema 146.
Migration of the accounts is parallelized. The default number of threads used is the number of available processors. This can be customized using the threadcount
system property.
Before the migration, gc --prune=now
is executed.
When hosted on FileRepository
, refs are packed after migration of every 1000 accounts.
A progress indicator counts every 100 accounts migrated.
Allow commit validation listeners to ignore the skip-validation
push option.
Gerrit allows certain users to skip validation of new commits by passing the skip-validation
push option.
A new method shouldValidateAllCommits
is added on the CommitValidationListener
, to allow plugin implemented validators to override this option and always be invoked for new commits. The new method has a default implementation that returns false
meaning that existing implementations don't need to be modified and will behave the same as before.
Optimize commit and ref operation validation for non-ff push.
On a non-ff push all the commits were validated before the ref operation was validated. On a push with many commits, validating all the commits is wasteful in the case where the ref operation is rejected. The logic is changed so that the ref operation validation is performed before the commit validation.
Disallow change index task duplication.
It was possible for multiple index tasks to be queued for the same change.
Fix formatting issues and inconsistencies in soy email templates.
Use URL Formatter interface to generate URL in outgoing emails.
Fix error message when JRE is not found when starting Gerrit.
The error message recommended to check for a JRE “>= 1.7”, but Gerrit requires Java 8 minimum.
Expose the createProject
method of the CreateProject
class to plugins.
This allows plugins to directly invoke the project creation, avoiding the checks that are performed when invoking via the apply
method.
Expose the jsr305 library in the plugin API.
Upgrade gitiles to 0.2-10.
Includes a fix for rendering of metalinks in the navigation bar.
