[Buildbot-devel] ForceScheduler and codebases

[Jared Grubb]

I've been playing with something locally, and wanted to run this idea by everyone ... and also get Harry's opinion, as he might already have something in the works.

First, I created a new Parameter class that represents a drop-down box + text box, which get presented in one line. It basically inherits from the ChoiceParameter class, but populates the property value based on the combination of the drop-down choice and the string (how those mix is configurable).

Then, for each code base, I create one of these parameters, with the drop-down box having the values ['HEAD', "Revision...", "Branch..."]. 'HEAD' causes no sourcestamp to be generated for that codebase. Revision would generate SS={codebase=x, revision=y}; branch gives SS={codebase=x, branch=y}. 

Then, the usual project/repo/branch/revision boxes are removed, since for a multi-codebase builder these are less helpful I think. 

Other thoughts:
* would be nice to allow the drop-down to be extensible, for example, adding specific branches (or renaming 'HEAD'  to trunk or master)
* could use javascript to hide the text box if it's not applicable (ie for the "HEAD" selection)
* so far this is git-specific. For SVN codebases, you might need to be able to specify both revision and branch?
* maybe "Tag" should be available?
* could think about later adding "+patch" and a file chooser
