Get a list of revisions that are candidates to be built.

This method is invoked on the node where the workspace exists, which may not be the master.

Parameters:

isPollCall - true if this method is called from pollChanges.

singleBranch - contains the name of a single branch to be built this will be non-null only in the simple case, in advanced cases with multiple repositories and/or branches specified then this value will be null.

git - Used for invoking Git

listener - build log

buildData - build data to be used Information that captures what we did during the last build.

context - Object that provides access back to the model object. This is because the build chooser can be invoked on an agent where there's no direct access to the build/project for which this is invoked. If isPollCall is false, then call back to both project and build are available. If isPollCall is true, then only the callback to the project is available as there's no contextual build object.

Returns:

the candidate revision. Can be an empty set to indicate that there's nothing to build.

Throws:

IOException - on input or output error

hudson.plugins.git.GitException - on git error

InterruptedException - when interrupted

Determines the baseline to compute the changelog against.

getCandidateRevisions(boolean, String, hudson.plugins.git.IGitAPI, TaskListener, BuildData, BuildChooserContext) determine what commits can be subject for a build, and for each commit it determines the branches that contribute to them.

Once GitSCM picks up a specific Revision to build, for each branch, in that revision, this method is called to compute the changelog.

Parameters:

branch - The branch name.

data - Information that captures what we did during the last build.

git - Used for invoking Git

context - Object that provides access back to the model object. This is because the build chooser can be invoked on an agent where there's no direct access to the build/project for which this is invoked.

Returns:

candidate revision. Can be an empty set to indicate that there's nothing to build.

Throws:

IOException - on input or output error

InterruptedException - when interrupted

prepareWorkingTree

public void prepareWorkingTree(org.jenkinsci.plugins.gitclient.GitClient git,

                        throws IOException,
                               InterruptedException

In a general case, a working tree is a left-over from the previous build, so it can be quite messed up (such as HEAD pointing to a random branch). This method is responsible to bring the working copy to a predictable clean state where candidate revisions can be evaluated.

Typical use-case is a BuildChooser which do handle pull-request merge for validation. Such a BuildChooser will run the merge on working copy, and expose the merge commit as getCandidateRevisions(boolean, String, org.jenkinsci.plugins.gitclient.GitClient, hudson.model.TaskListener, BuildData, BuildChooserContext)

Parameters:

git - client to execute git commands on working tree

listener - build log

context - back-channel to master so implementation can interact with Jenkins model

Throws:

IOException - on input or output error

InterruptedException - when interrupted
