NoteDb is now required for accounts (since 2.15) and groups (since 2.16), and is the preferred storage for changes.
When upgrading to Gerrit v2.16, you are strongly advised to migrate fully (including changes) from ReviewDb to NoteDb.
Although ReviewDb is still technically available on Gerrit v2.16, the upgrade to NoteDb is strongly recommended, although not enforced.
Note that in the next version of Gerrit (v3.0), ReviewDb will not be available.
This release contains schema changes. To upgrade:
java -jar gerrit.war init -d ${site_path}
For logging Gerrit is now using Flogger instead of SLF4J. The logging backend is still LOG4J.
The Flogger LOG4J backend is configured by a system property (flogger.backend_factory=com.google.common.flogger.backend.log4j.Log4jBackendFactory#getInstance) that must be set for logging to work. There is an init step that automatically sets this system property in the gerrit.config file and in addition Gerrit tries to set this system property automatically on startup if it isn't set yet. However for some setups you may need to do additional actions to make sure that this system property is set.
In addition there is a system property that needs to be set for request tracing (flogger.logging_context=com.google.gerrit.server.logging.LoggingContext#getInstance). Also this system property is automatically set in the gerrit.config file by an init step and in addition Gerrit tries to set this system property automatically on startup if it isn't set yet. However for some setups you may need to do additional actions to make sure that this system property is set.
SLF4J can still be used by plugins, but using SLF4J in plugins is deprecated and with the next Gerrit release SLF4J will no longer be exported as part of the Gerrit plugin API jar. This means from the next release onwards, plugins must either migrate to Flogger or have an own dependency on SLF4J.
Gerrit 2.16 introduces a new secondary index for projects. The initial version of this index must be created by running the offline reindex before starting Gerrit:
java -jar gerrit.war reindex --index projects -d ${site_path}
The group index gained two new fields, which Gerrit 2.16 depends on. For this reason, the following command to offline reindex the group index must be executed as well:
java -jar gerrit.war reindex --index groups -d ${site_path}
The offline reindex for groups should also be run on Gerrit slave hosts.
Note that if you are migrating from v2.15, it is not necessary to reindex the changes and accounts indexes offline. These will automatically be reindexed by the online reindexer after starting Gerrit.
You should review the documentation on NoteDb, including the information about the migration process:
In Gerrit 2.15:
In Gerrit 2.16:
gerrit.war init).From 2.16 GWT UI is deprecated and will be removed in a future version.
In version 2.14 support for Soy templates was added. For backwards compatibility, support for Velocity templates (VTL) was kept.
In version 2.16 support for VTL is completely removed. Site administrators must replace any Velocity templates (.vm files in $site/etc/mail/) with the equivalent Soy templates before upgrading to this version.
The possibility to push to refs/changes is now disabled by default. It is still possible to enable it in the gerrit config by setting receive.allowPushToRefsChanges to true.
Some proxies, which are not under client control, prohibit DELETE requests with bodies. DELETE requests with bodies could work on a first attempt, but could fail afterwards because a server they have no control over was updated. In this case, client users could be in trouble if they were not notified.
Therefore, we have decided to no longer recommend sending DELETE requests with bodies. They will continue to work in this release but should be considered as deprecated and will be removed in the next release.
flexmark-java is a Java implementation of CommonMark 0.28 spec parser using the blocks first, inlines after Markdown parsing architecture.
Its strengths are speed, flexibility, Markdown source element based AST with details of the source position down to individual characters of lexemes that make up the element and extensibility, compared to Pegdown speed that was, in general, less than ideal and for pathological input either hangs or practically hangs during parsing.
This table was used to retrieve the site_path directory in unattended setup mode. As a replacement, system property gerrit.site_path should be used.
Support for upload pack with git protocol version 2 can be enabled by setting receive.enableProtocolV2 in gerrit.config and adding the configuration:
[protocol] version = 2
either in the gerrit user‘s ~/.gitconfig to enable for all repositories, or on a per repository basis in each repository’s config file on the server.
On the client side, the same protocol.version must be set either in the user‘s ~/.gitconfig or in the repository’s .git/config file.
There are several new REST endpoints and additions to existing endpoints, as described in the REST API documentation.
See below an overview of the noteworthy changes.
ProjectAccessInfo has a new field configWebLinks containing a list of URLs that display the history of the configuration file governing this project’s access rights.Query accounts requires the Modify Account permission to return the all the emails associated with the account.
New endpoint /drafts.delete to remove the drafts comments associated with an account.
New endpoints to lists, get and delete the messages /messages of a change including the detailed account information associated.
New endpoint /cherrypick to cherry-pick a specific commit.
New endpoint /server/reload to reload Gerrit configuration.
New endpoint /server/preferences.edit to retrieve and update the global edit preferences for the server.
?ownedBy to find groups that are owned by another groupNew option ?state to get all projects with the given state.
New option ?query for querying projects limited to a maximum of ?limit entries.
New endpoint /description for updating and deleting the project's description.
Check project access endpoint is now a GET API while the POST is still supported by deprecated.
New endpoint to index a project /index and all the changes /index.changes associated to it.
New endpoint /check to check project's consistency.
/files to list files associated with a commit.For each REST endpoint tracing can be enabled by setting the trace=<trace-id> request parameter. Given the trace ID an administrator can find the corresponding logs and investigate issues more easily.
A new option for Review Labels, label.Label-Name.ignoreSelfApproval, is available.
If true, the label may be voted on by the uploader of the latest patch set, but their approval does not make a change submittable. Instead, a non-uploader who has the right to vote has to approve the change.
It defaults to false, but one possible use case is to set the value to true for the Code-Review label in the All-Projects project. That value will then be inherited by all projects that do not override the Code-Review label settings.
A new core plugin, codemirror-editor, is available, which uses CodeMirror to provide a rich code editing experience in PolyGerrit.
When you upgrade Gerrit using init -d, you are given the option to install the codemirror-editor plugin.
Tracing can now be enabled for single requests. If a request is traced a unique trace ID is attached to all logs that are triggered by the request. In addition all logs are enforced regardless of the configured log level. Given the trace ID an administrator can find the trace in the error log and debug issues more easily. Detailed information about request tracing can be found in the request tracing documentation.
