Previously, not passing a UUID when instantiating an SVNMeta instance
would cause it to succeed even if no UUID was previously known. First
when the UUID was actually read would an exception be raised.
This slight refactoring of _set_uuid() makes it so an exception is
raised immediately. While at it, the exception message is changed to
be slightly more accurate and helpful.
The previous assertStringEqual() utility method pointed to standard
output. This is fairly annoying when running our own test-runner as it
suppresses that output. The assertMultiLineEqual() method shows
essentially the same information in the AssertionError itself.
While at it, all other comparisons that contain line-breaks are made
to use assertMultiLineEqual().
The 'hg svn url' command has been killed; the replacement is
'.hg/hgrc'. More stuff related to its disappearance has been stripped,
including two tests.
HgChangeReceiver now takes a UUID argument, which it uses to ensure
that remote repositories remain unchanged. This is a temporary
solution, and I'm not entirely satisfied with how it's done either.
Access to the UUID file has been isolated in a HgChangeReceiver
property.
Some more tests have been updated to use ui.pushbuffer()/popbuffer(),
and to pass through the Mercurial API.
Moved the arguments to wrappers.pull() to the UI configuration.
Also, remove HgChangeReceiver.opts in favour of a 'usebranchnames'
instance & configuration variable. The name is taken from the
ConvertExtension.
