This document contains information about adding a build configuration and buildslave to private slave builder to LLVM Buildbot Infrastructure. Check the existing build configurations to make sure the one you are interested in is not covered yet or gets built on your computer much faster than on the existing one. We prefer faster builds so developers will get feedback sooner after changes get committed. The computer you will be registering with the LLVM buildbot infrastructure should have all dependencies installed and you can actually build your configuration successfully. Please check what degree of parallelism -j param would give the fastest build.

BuildStep s are usually specified in the buildmaster's configuration file, in a list that goes into the BuildFactory. The BuildStep instances in this list are used as templates to construct new independent copies for each build so that state can be kept on the BuildStep in one build without affecting a later build. Each BuildFactory can be created with a list of steps, or the factory can be created empty and then steps added to it using the addStep method:. The basic behavior for a BuildStep is to:.
The rest of this section describes all the standard BuildStep objects available for use in a Build , and the parameters which can be used to control each. A full list of build steps is available in the Build Step Index. All BuildStep s accept some common parameters. Some of these control how their individual status affects the overall build. Others are used to specify which Locks see Interlocks should be acquired before allowing the step to run.
Arguments common to all BuildStep subclasses:. A step can be optionally hidden from the waterfall and build details web pages. To do this, set the step's hideStepIf to a boolean value, or to a function that takes one parameter, the BuildStepStatus and returns a boolean value. Steps are always shown while they execute, however after the step as finished, this parameter is evaluated if a function and if the value is True, the step is hidden.
For example, in order to hide the step if the step has been skipped,. At the moment, Buildbot contains two implementations of most source steps.
The new implementation handles most of the logic on the master side, and has a simpler, more unified approach. The older implementation Source Checkout Slave-Side handles the logic on the slave side, and some of the classes have a bewildering array of options.
Master-side source checkout steps are recently developed and not stable yet. If you find any bugs please report them on the Buildbot Trac. New users should, where possible, use the new implementations.
The old implementations will be deprecated in a later release. Old users should take this opportunity to switch to the new implementations while both are supported by Buildbot. Some version control systems have not yet been implemented as master-side steps. If you are interested in continued support for such a version control system, please consider helping the Buildbot developers to create such an implementation. In particular, version-control systems with proprietary licenses will not be supported without access to the version-control system for development.
All source checkout steps accept some common parameters to control how they get the sources and where they should be placed. The remaining per-VC-system parameters are mostly to specify where exactly the sources are coming from.
These two parameters specify the means by which the source is checked out. The mode parameter a string describing the kind of VC operation that is desired, defaulting to incremental. The options are. Methods are specific to the version-control system in question, as they may take advantage of special behaviors in that version-control system that can make checkouts more efficient or reliable.
The name of this parameter might vary depending on the Source step you are running. The concept explained here is common to all steps and applies to repourl as well as for baseURL when applicable. This grabs the repository from the source stamp of the build. This can be a security issue, if you allow force builds from the web, or have the WebStatus change hooks enabled; as the buildslave will download code from an arbitrary repository.
The Mercurial build step performs a Mercurial aka hg checkout or update. Branches are available in two modes: dirname , where the name of the branch is a suffix of the name of the repository, or inrepo , which uses hg's named-branches support. Make sure this setting matches your changehook, if you have that installed. Mercurial's incremental mode does not require a method.
The full mode has three methods defined:. The Git build step clones or updates a Git repository and checks out the specified branch or revision. Note that the buildbot supports Git version 1. The argument should either be a bool or dict , and will change how git describe is called:.
Each key's value can be False or None to explicitly skip that argument. For the following keys, a value of True appends the same-named git argument:. For the following keys, an integer or string value depending on what git expects will set the argument's parameter appropriately. Examples show the key-value pair:.
The SVN build step performs a Subversion checkout or update. There are two basic ways of setting up the checkout step, depending upon whether you are using multiple branches or not. The SVN step should be created with the repourl argument:. If you are building from multiple branches, then you should create the SVN step with the repourl and provide branch information with Interpolate :.
Alternatively, the repourl argument can be used to create the SVN step without Interpolate :. Only available if slave has Subversion 1. If set to empty updates will not pull in any files or subdirectories not already present.
If set to files , updates will pull in any files not already present, but not directories. If set to immediates , updates will pull in any files or subdirectories not already present, the new subdirectories will have depth: empty. If set to infinity , updates will pull in any files or subdirectories not already present; the new subdirectories will have depth-infinity. Infinity is equivalent to SVN default update behavior, without specifying any depth argument.
If you are using branches, you must also make sure your ChangeSource will report the correct branch names. No method is needed for incremental mode. For full mode, method can take the values shown below.
If no value is given, it defaults to fresh. The repository-vs-workspace model is similar to Darcs, but it uses a strictly linear sequence of revisions one history per branch like Arch. Branches are put in subdirectories. This makes it look very much like Mercurial.
This section describes the more mature slave-side source steps. Where possible, new users should use the master-side source checkout steps, as the slave-side steps will be removed in a future version.
See Source Checkout. The first step of any build is typically to acquire the source code from which the build will be performed. There are several classes to handle this, one for each of the different source control system that Buildbot knows about. For a description of how Buildbot treats source control in general, see Version Control Systems. Defaults to update. The name of this parameter might varies depending on the Source step you are running.
The concept explained here is common to all steps and applies to repourl as well as for baseURL when aplicable. Buildbot, now being aware of the repository name via the change source, might in some cases not need the repository url. There are multiple way to pass it through to this step, those correspond to the type of the parameter given to this step:. My habit as a developer is to do a cvs update and make each morning. Problems can occur, either because of bad code being checked in, or by incomplete dependencies causing a partial rebuild to fail where a complete from-scratch build might succeed.
On the other hand, other kinds of dependency problems can cause a clean build to fail where a partial build might succeed. This frequently results from a link step that depends upon an object file that was removed from a later version of the tree: in the partial tree, the object file is still around even though the Makefiles no longer know how to create it.
Each VC system has a corresponding source checkout class: their arguments are described on the following pages. It takes the following arguments:. The most versatile way to create the SVN step is with the svnurl argument:. The svnurl argument can be considered as a universal means to create the SVN step as it ignores the branch information in the SourceStamp. Alternatively, if you are building from multiple branches, then you should preferentially create the SVN step with the baseURL and defaultBranch arguments instead:.
This will be appended to baseURL to create the string that will be passed to the svn checkout command. It is possible to mix to have a mix of SVN steps that use either the svnurl or baseURL arguments but not both at the same time. If set to "empty" updates will not pull in any files or subdirectories not already present. If set to "files", updates will pull in any files not already present, but not directories.
If set to "immediates", updates willl pull in any files or subdirectories not already present, the new subdirectories will have depth: empty. If set to "infinity", updates will pull in any files or subdirectories not already present; the new subdirectories will have depth-infinity. The Darcs build step performs a Darcs checkout or update. Like SVN , this step can either be configured to always check out a specific tree, or set up to pull from a particular branch that gets specified separately for each build.
In other words, doing an SVN checkout of baseURL is legal, but silly, since you'd probably wind up with a copy of every single branch in the whole repository. Doing a Darcs checkout of baseURL is just plain wrong, since the parent directory of a collection of Darcs repositories is not itself a valid repository.
Branches are available in two modes: dirname like Darcs , or inrepo , which uses the repository internal branches. The P4 Slave-Side build step creates a Perforce client specification and performs an update. The Git step takes the following arguments:. The BK build step performs a BitKeeper checkout or update.
Buildbot use is deprecated, however at this time it is still required for software release and distribution. If you are a package maintainer and need buildbot access, open a ticket assigned to the SQuaRE team. Buildbot is a confederation of: a Buildmaster which schedules builds according to periodic-, user initiated- and SCM- triggers; Builders which carry out a static sequence of commands called Build Steps; and Buildslaves which provide compute resources on remote hosts. The build step return can affect whether the next build step in the predefined sequence is invoked this is the closest to real-time step specification as exists. This attribute has been used to continue processing build steps even though an earlier step failed - sometimes that is appropriate, and sometimes, it is not. The view of a specific Builder provides status on past, present and future build requests and user input fields allowing the user to:.
Buildbot is an open-source framework for automating software build, test, and release processes. Buildbot is a framework in which you implement a system that matches your workflow and grows with your organization. Buildbot supports distributed, parallel execution of jobs across multiple platforms, flexible integration with version-control systems, extensive status reporting, and more. At its core, Buildbot is a job scheduling system: it queues jobs, executes the jobs when the required resources are available, and reports the results. Your Buildbot installation has one or more masters and a collection of workers. The masters monitor source-code repositories for changes, coordinate the activities of the workers, and report results to users and developers.
