Buildbot and mutliple SVN projects

So as you all know by now I have been using buildbot to compile and upload code to my arduino.

This took so work as my SVN repo is laed out as follows;

SVN / Project 1 / branches
                / tags
                / trunk
    / Project 2 / branches
                / tags
                / trunk
 

So how do you make buildbot "see" the change in a project and compile just that project? You use a file splitter.

In the master.cfg you place a file splitter like the following one

########## Custom file spliter

def my_file_splitter(path):
    print "path " +  path
    pieces = path.split('/')
    if pieces[0] == 'trunk':
        branch = None
        pieces.pop(0) # remove 'trunk'
    elif pieces[0] == 'branches':
        pieces.pop(0) # remove 'branches'
        # grab branch name
        branch =  None
        projectname = None
        return
    elif pieces[0] == 'RETIRED':
        branch = None
        projectname = None
        return
    else:
        branch = pieces.pop(0)
    projectname = pieces.pop(0)
    print branch
    print projectname
    return (branch, '/'.join(pieces))

This splits the path to find where the change is and ignores any change but trunk.

This splitter is called by the Poller on the repo like like the following

SVNPoller(
         "svn://localhost/data/svn/arduino/"
         , cachepath="/tmp/arduino"
         , pollinterval=30
         , split_file=my_file_splitter
         )

Once this is all time it time to setup the build factory to use the properties of the splitter.

arduino = BuildFactory()
arduino.addStep(ShellCommand(command=["pwd"],workdir= WithProperties("build/%s", 'branch'), usePTY=True))
arduino.addStep(ShellCommand(command=["rm","-fr",WithProperties("%s*", 'branch')],workdir="build/",usePTY=True))
arduino.addStep(ShellCommand(command=["svn", "co",  WithProperties("svn://localhost/data/svn/arduino/%s" ,'branch') , Property('branch')],workdir="build/",usePTY=True))
arduino.addStep(ShellCommand(command=["pwd"],workdir= WithProperties("build/%s", 'branch'), usePTY=True))
arduino.addStep(ShellCommand(command=["ls", "-l"],workdir= WithProperties("build/%s", 'branch'),usePTY=True))
arduino.addStep(ShellCommand(command=["trunk/build.sh"],workdir= WithProperties("build/%s", 'branch'), usePTY=True))
