rhg: fallback when encountering ellipsis revisions
Ellipsis revisions are still experimental and buggy in non-trivial
histories. We currently have no plans to improve this situation nor
to add support for ellipsis revisions in `rhg`.
Falling back should be done carefully (since we may have already done
some work that is visible to the user), but in this case it's highly
unlikely that we're doing anything useful with a repo with ellipsis
revisions, so this should be strictly better, also since the
error message is more explicit.
dirstate-v2: hash the source of the ignore patterns as well
Fixes the test introduced in the last changeset. This caused the hash
to change, which means that the check in the test had to be adapted.
Since this hash is only done as a caching mechanism, invalidation does
not pose any backwards compatibility issues.
dirstate-v2: add test that shows a collision in ignore patterns hash
This hash is used for optimizing dirstate `status`. We demonstrate that the
hash is incorrectly ignoring the changes to the semantics of the ignore
files just because the contents (but not their source) haven't changed.
This is fixed in the next changeset.
testlib: add `--raw-sha1` option to `f`
This will be used in the patch fixing the ignore hash collision in
dirstate-v2 to check the behavior of the new hashing function.
rust-status: save new dircache even if just invalidated
There was a functional race between invalidating the cache (not acted upon
until the end of the status algorithm) and populating the new cache (which
relies upon an up-to-date version of the cache).
We simply inform the cache populating function that we've just invalidated
the cache for this particular directory since the information is present in
the same scope.
