Mercurial specific VC operation. In addition to the arguments handled by SourceBaseCommand, this command reads the following keys:

['repourl'] (required): the Mercurial repository string ['clobberOnBranchChange']: Document me. See ticket #462.

Method Details

sourcedirIsUpdateable(self)

doVCUpdate(self)

source code

doVCFull(self)

source code

Returns a deferred with the steps to do a fresh checkout.

Overrides: base.SourceBaseCommand.doVCFull: (inherited documentation)

parseGotRevision(self)

source code

Override this in a subclass. It should return a string that represents which revision was actually checked out, or a Deferred that will fire with such a string. If, in a future build, you were to pass this 'got_revision' string in as the 'revision' component of a SourceStamp, you should wind up with the same source code as this checkout just obtained.

It is probably most useful to scan self.command.stdout for a string of some sort. Be sure to set keepStdout=True on the VC command that you run, so that you'll have something available to look at.

If this information is unavailable, just return None.
