IntroductionThe local trybot allows you to emulate a buildbot run on your local machine with a set of your changes. The changes are patched to tip of tree (TOT). They should be very similar to remote tryjobs in most regards. For Google developers, please also take a look at the Remote Trybot documentation. NOTE: The first time you run the trybot it will sync down a fresh checkout of the source, build a new chroot and board, which will make the initial run take longer than subsequent runs. An incremental run with an existing board takes 30min-40min. Pre-instructions (These are important!)
To do so, run the following from within your repo source checkout:
To patch in a gerrit CL3a. Runcros tryjob --local -g '[*]<cl_1> [*]<cl_2> .. [*]<cl_N>' config Substitute <config> with your desired config. Prepend a '*' to the CL ID to indicate it's an internal CL. The CL ID can be a Gerrit Change-ID or a change number. An example: cros tryjob --local -g 12345 -g *4168 samus-paladin-tryjob This patches in three CL's: 1) an external CL using Gerrit change-ID 2) an external CL using Gerrit change number 3) internal CL using change-iD. In case a CL has several patches associated with it, the latest patch is used. 3c. Run cros tryjob -p '<project1>[:<branch1>]...<projectN>[:<branchN>]' config Specify the name of the project (not the path) and optionally the project branch. If no branch is specified the current branch of the project will be used. NOTE: To get the project name of the project you're working on run repo list. NOTE: Do not do development within the trybot buildroot! Your changes will get wiped out on the next trybot run. Develop within your source root, and patch in changes. NOTE: Use the --nosync option to prevent the trybot from updating its source checkout. See the Tips section below for more info.
NOTE: The output of the trybot is automatically saved to a cbuildbot.log file in <trybot_root>/cbuildbot_logs. The log directory is printed out at the end of a run. The first time you run the trybot, it will sync down its own checkout of the source, and build its own chroot. The CL's you specify to patch are patched to the trybot's own source tree. When you specify local changes to patch (by specifying a project and branch the changes are on) the trybot will generate git patch files based on those changes and apply the patch files to its private source checkout. When you specify a Gerrit changelist, the trybot will look up the changelist info from Gerrit, fetch the ref of the change, and rebase it to TOT in its private source checkout. FeedbackThanks for using the trybot! Please contact chromium-os-dev@chromium.org for any issues you run into. Please report any bugs you find, and file feature requests. There will be active development on the trybot, so please sync to the latest version before you run it. |
