convert: backout b75a04502ced and 9616b03113ce - tagmap Tagmap solves a very specific use case. It would be better to have a more generic solution than to have to maintain this forever. Tagmap has not been released yet and removing it now will not break any backward compatibility contract. There is no test coverage for tagmap but it seems like the same can be achieved with a (relatively) simple and much more powerful custom extension: import hgext.convert.hg def f(tag): return tag.replace('some', 'other') class source(hgext.convert.hg.mercurial_source): def gettags(self): return dict((f(tag), node) for tag, node in in super(source, self).gettags().items()) def getfile(self, name, rev): data, flags = super(source, self).getfile(name, rev) if name == '.hgtags': data = ''.join(l[:41] + f(l[41:]) + '\n' for l in data.splitlines()) return data, flags hgext.convert.hg.mercurial_source = source
