Well, another way to make the code here work better is to do the test
case 'should I test tags' by roughly:
branch = self.make_branch()
if not branch._format.supports_tags():
The basic problem though is that format, which indeed represents disk
formats in the abstract has trouble talking about formats whose
capabilities vary by url to url.
Consider for instance a tree disk format which can do 'full unix
permissions'. On windows it might degrade to 'x bit only', but on unix
do user,group,write,execute etc.
I intended formats to be a factory for two things:
- creating instances on disk and memory at the same time
- opening existing instances from disk
and provide code-path detection for upgrades/downgrades
I think we have to stop using formats as a proxy for 'what the branch
object is capable of', because disk format is not the entire story - and
the smart server is just the easiest example to talk about and consider,
not the only example.
