py3: use .startswith() instead of bytes[0] Doing bytes[0] will return the ascii value of that position which breaks comparison with a bytechar. This makes test-absorb.t work again on py3. Differential Revision: https://phab.mercurial-scm.org/D6508

rust-regex: fix shortcut for exact matches The current shortcut for rootglobs that can be simplified to exact matches does not work, it instead treats the pattern as a regex, which is not the same thing. This changes fixes the behavior and introduces a test for this behavior. Differential Revision: https://phab.mercurial-scm.org/D6489

rust-filepatterns: use bytes instead of String In my initial patch, I introduced an unnecessary hard constraint on UTF-8 filenames and patterns which I forgot to remove. Although the performance penalty for using String might be negligible, we don't want to break compatibility with non-UTF-8 encodings for no reason. Moreover, this change allows for a cleaner Rust core API. This patch introduces a new utils module that is used with this fix. Finally, PatternError was not put inside the Python module generated by Rust, which would have raised a NameError. Differential Revision: https://phab.mercurial-scm.org/D6485

phabricator: make `hg debugcallconduit` work outside a hg repo I am trying to write some automations around phabricator and having debugcallconduit work outside a hg repo will be nice!

phabricator: pass ui instead of repo to callconduit This will help us make `hg debugcallconduit` work outside a hg repo as next patch will mark that command as no repo. Differential Revision: https://phab.mercurial-scm.org/D6498

phabricator: pass ui into readurltoken instead of passing repo The goal of this series is to make `hg debugcallconduit` work outside of a hg repo. This patch, removes requirement of repo object from readurltoken as we only need ui there. It also updates the callers to pass in ui instead of repo.

phabricator: add commenting to phabsend for new/updated Diffs Especially useful when sending updates to existing Revisions so one can specify the sort of changes e.g. "Address review comments" or "Rebase to tip" If the diff content hasn't changed then it only needs a metadata update which doesn't show in the Phabricator updates UI, so don't add a comment that will.
