revlog: use the user facing filename as the display_id for filelogs I had trouble isolating some LFS blob corruption detected by `hg verify` because the traceback referenced a file, but with the `data/` prefix in the `.hg/store` path, so it couldn't be located with the `file()` revset: ``` Traceback (most recent call last): File "/mnt/d/mercurial/mercurial/revlog.py", line 3209, in verifyintegrity _verify_revision(self, skipflags, state, node) File "/mnt/d/mercurial/hgext/lfs/wrapper.py", line 246, in _verify_revision orig(rl, skipflags, state, node) File "/mnt/d/mercurial/mercurial/revlog.py", line 158, in _verify_revision rl.revision(node) File "/mnt/d/mercurial/mercurial/revlog.py", line 1816, in revision return self._revisiondata(nodeorrev, _df) File "/mnt/d/mercurial/mercurial/revlog.py", line 1870, in _revisiondata self.checkhash(text, node, rev=rev) File "/mnt/d/mercurial/mercurial/revlog.py", line 1996, in checkhash % (self.display_id, pycompat.bytestr(revornode)) mercurial.error.RevlogError: integrity check failed on data/EXE/PPC/shrinksrec.exe:0 ``` (I'm a little surprised it resulted in a stacktrace instead of just a message, but that's a different issue. I'm also not sure how to trigger the simplestore case, since IIUC, it's also a revlog based store.) It's not clear how to handle the changelog and manifest (because the user doesn't interact with them as a file), so those cases are left alone. The other thing that would be nice to improve somehow is to indicate that the ":0" is a revlog revision, not the changeset revision that users are used to. I'm not sure how to handle the "or node" part though.

== New Features ==

 * `hg mv -A` can now be used with `--at-rev`. It behaves just like
   `hg cp -A --at-rev`, i.e. it marks the destination as a copy of the
   source whether or not the source still exists (but the source must
   exist in the parent revision).

 * New revset predicate `diffcontains(pattern)` for filtering revisions
   in the same way as `hg grep --diff pattern`.

 * The memory footprint per changeset and per file during pull/unbundle
   operations has been significantly reduced.


== New Experimental Features ==



== Bug Fixes ==



== Backwards Compatibility Changes ==



== Internal API Changes ==

 * `merge.update()` is now private (renamed to `_update()`). Hopefully
   the higher-level functions available in the same module cover your
   use cases.

 * `phases.registernew` now takes a set of revisions instead of a list
   of nodes. `phases.advanceboundary` takes an optional set of revisions
   in addition to the list of nodes. The corresponeding members of the
   `phasecache` class follow this change.

 * The `addgroup` member of `revlog` classes no longer keeps a list of
   all found nodes. It now returns True iff a node was found in the group.
   An optional callback for duplicated nodes can be used by callers to keep
   track of all nodes themselve.

 * The `_chaininfocache` of `revlog` classes has been changed from a dict
   to a LRU cache.
