setup.py will break when dealing with non -dev version

[joca16]

This refers to version 9.3, as in https://github.com/apple/ccs-calendarserver/blob/df3d001ec81ad734534740eda69b70a57656f16e/setup.py setup.py breaks when dealing with a branch that has no "-dev" ending, as with git clone -b release/CalendarServer-9.3 https://github.com/apple/ccs-calendarserver.git See comments with #! (I have no clear idea what is intended with the beta stuff, so there is no pull request here...)

setup.py, line 142ff if info["branch"].startswith("release/"): project_version = info["branch"][len("release/"):] project, version, dev = project_version.split("-") #!will break when there is only one hyphen "-" assert project == project_name, ( "Branched project {!r} != {!r}".format(project, project_name) ) assert version == base_version, ( "Branched version {!r} != {!r}".format(version, base_version) ) assert dev == "dev", ( #!there might be no "dev" in the project version. "Branch name doesn't end in -dev: {!r}".format(info["branch"])
