localrepo: rename in-memory tag cache instance attributes (
issue548).
- self.tagscache to self._tags
- self._tagstypecache to self._tagtypes
- this is for consistency, readability, privacy, and to subtly hint
that "caching" is something else
localrepo: factor _findtags() out of tags() (
issue548).
This makes in-memory caching the sole responsibility of localrepo,
eliminating some localrepo code that was duplicated in mq and
bookmarks.
test-tags: enhance the test to probe tag caching better (
issue548).
- give detailed dumps of .hgtags and localtags content
- repeat some query operations to expose cache bugs
- ensure that rollback/strip undo tagging operations
test-tags: clarify test output; simplify test script a bit (
issue548).
- use simpler way ('hg id') to get current changeset id
- add 'echo' statements to guide the eye when reading output
- add some more output to clarify the state of .hgtags
- drop '-d' option from every commit/tag, since run-tests.py
does this (although with a different timestamp, so changeset
ids differ)
