dirstate: walk returns None for files that have a symlink in their path
Previously dirstate.walk would return a stat object for files in the dmap
that have a symlink to a directory in their path. Now it will return None
to indicate that they are no longer considered part of the repository. This
currently only affects walks that traverse the entire directory tree (ex:
hg status) and not walks that only list the contents of the dmap (ex: hg diff).
In a situation like this:
mkdir foo && touch foo/a && hg commit -Am "a"
mv foo bar
ln -s bar foo
'hg status' will now show '! foo/a', whereas before it incorrectly considered
'foo/a' to be unchanged.
In addition to making 'hg status' report the correct information, this will
allow callers to dirstate.walk to not have to detect symlinks themselves,
which can be very expensive.
pathauditor: add check() method
The pathauditor currently throws exceptions when it encounters an invalid
path. This change adds a method to allow people to treat it as a boolean.
This is currently used by scmutil.addremove and in a subsequent patch it
will be used by dirstate.walk
summary: show active bookmark even if not at current changeset
Before this change, 'hg summary' would not show the active bookmark
unless it pointed to the working directory parent. After this change, it
will show it in parentheses, like so:
parent: 18581:
f0ff45fe6700 tip
summary: simplify handling of active bookmark
branch: default
bookmarks: [crew]
commit: (clean)
update: (current)
summary: test that current bookmark isn't shown
This exposes the current behavior in a test. A later change will make
summary show when the active bookmark has moved out from under us.
