parsers: ensure revlog index node tree is initialized before insertion
Currently, the revlog index C implementation assumes its node tree will be
initialized before a new element is inserted by revnum. For example, revlog.py
executes 'self.index.insert(-1, e)' in _addrevision(). This is only safe
because the node tree has been initialized by a "node in self.nodemap"
check made in addrevision().
(For context, this was discovered while developing an experimental revlog
mixin which stores "elided nodes" via a separate code path from
_addrevision(); that new code path segfaults without this patch.)
revset: add 'only' to DoS-safe symbols
There is no reason to disable it in hgweb because the same query can be
written without using 'only()'.
tests: drop unnecessary glob that causes a warning on Windows
This was triggered by
3778884197f0.
merge: add test with conflicting file and remote directory rename
Changset
88629daa727b (merge: demonstrate that directory renames can
lose local file content, 2014-12-02) should clearly have added the
reverse version of the test: where the remote side renamed a
directory, added a new file in that directory, and the local directory
added a conflicting file in the source directory. Add such a test now,
and also touch up the ones already added slightly (e.g. 'local' was a
stupid value for content that can be on either side of a merge).
graft: use a real conflict for the tests
One of the graft tests grafts a changeset that changes a file's
content from 'a' to 'b' onto a branch that has changed the file's
content from 'a', via 'b', and then back to 'a' again. To prepare for
not considering this a file in need of merging, let's use 'c' as the
file's new content to make sure it has to be considered
conflicting.
There's a second similar case further down where an ancestor is
grafted. Make sure that is also considered a conflict.
add: use lexists so that broken symbolic links are added
This restores the add behavior prior to
d8cdd46f426d and matches the
behavior of addremove.
