4.4.8. Release Notes for Buildbot 0.9.0b8¶

The following are the release notes for Buildbot 0.9.0b8 This version was released on April 11, 2016.

See Upgrading to Nine for a guide to upgrading from 0.8.x to 0.9.x

4.4.8.1. Master¶

Features¶

GitPoller now has a buildPushesWithNoCommits option to allow the rebuild of already known commits on new branches.
Add GitLab authentication plugin for web UI. See buildbot.www.oauth2.GitLabAuth.
DockerLatentWorker now has a hostconfig parameter that can be used to setup host configuration when creating a new container.
DockerLatentWorker now has a networking_config parameter that can be used to setup container networks.
The DockerLatentWorker volumes attribute is now renderable.
CMake build step is added. It provides a convenience interface to CMake build system.
MySQL InnoDB tables are now supported.
HttpStatusPush has been ported to reporter API.
StashStatusPush has been ported to reporter API.
GithubStatusPush has been ported to reporter API.
summaryCB of GerritStatusPush now gets not only pre-processed information but the actual build as well.
EC2LatentWorker supports VPCs, instance profiles, and advanced volume mounts.

Fixes¶

Fix loading LdapUserInfo plugin and its documentation (bug #3371).
Fix deprecation warnings seen with docker-py >= 1.4 when passing arguments to docker_client.start().
GitHubEventHandler now uses the ['repository']['html_url'] key in the webhook payload to populate repository, as the previously used ['url'] and ['clone_url'] keys had a different format between push and pull requests and GitHub and GitHub Enterprise instances.
Fix race condition where log compression could lead to empty log results in reporter api
Error while applying db upgrade is now properly reported in the buildbot upgrade-master command line.
Made Interpolate safe for deepcopy or serialization/deserialization
Optimized UI REST requests for child builds and change page.
Fix DockerLatentWorker use of volume parameter, they now propely manage src:dest syntax.
Fix DockerLatentWorker to properly create properties so that docker parameters can be renderable.
Lock down autobahn version for python 2.6 (note that autobahn and twisted are no longer supporting 2.6, and thus do not receive security fixes anymore).
Fix docs and example to always use port 8020 for the web ui.

Deprecations, Removals, and Non-Compatible Changes¶

Deprecated workdir property has been removed, builddir property should be used instead.
To support MySQL InnoDB, the size of six VARCHAR(256) columns changes.(author, branch, category, name); object_state.name; user.identifier was reduced to VARCHAR(255).
StatusPush has been removed from buildbot.

Please use the much simpler HttpStatusPush instead.

Changes for Developers¶

Worker changes described in below worker section will probably impact a buildbot developer who uses undocumented 'slave' API. Undocumented APIs have been replaced without failover, so any custom code that uses it shall be updated with new undocumented API.

4.4.8.2. Worker¶

Package buildbot-slave is being renamed buildbot-worker. As the work is not completly finished, neither buildbot-slave==0.9.0b8 or buildbot-worker==0.9.0b8 have been released.

You can safely use any version of buildbot-slave with buildbot==0.9.0b8, either buildbot-slave==0.8.12 or buildbot-slave==0.9.0b7.

4.4.8.3. Transition to "worker" terminology¶

Since version 0.9.0 of Buildbot "slave"-based terminology is deprecated in favor of "worker"-based terminology.

For details about public API changes see Transition to "worker" terminology.
