py3: encode JSON str to bytes json.dumps() will emit UTF-8 str on Python 2 and 3. Use sysbytes to force the .encode('utf-8') on Python 3 and no-op on Python 2. Differential Revision: https://phab.mercurial-scm.org/D4965

revlog: optimize ancestors() to not check filtered revisions for each While reviewing the Rust implementation, I noticed iter(ancestors) doesn't need to check filtering state for each parent revision. And doing that appears to have some measurable perf win. $ hg perfancestors -R mercurial (orig) wall 0.038093 comb 0.040000 user 0.040000 sys 0.000000 (best of 100) (this) wall 0.024795 comb 0.020000 user 0.020000 sys 0.000000 (best of 117)

phabricator: drop support for the legacy phabricator.auth.token config (BC) The test for this broke in dc82ad1b7f77 when statistics started being tracked. It wasn't noticed because none of the bots have the vcr module installed. It looks like the custom_patches argument should patch in the custom httpconnection, and I can't figure out what is going on.

absorb: print '{rev}:' as a prefix to the hash I don't see a sane way to print the summary to identify the changed commit, but this at least makes it a bit easier to identify a commit when a group of them changes.

packaging: fix "make centos{5,6,7}" Without this change, make centos{5,6,7} fails with error: cp: cannot stat '<basedir>/rpmbuild/RPMS/*/*': No such file or directory This change is the exact equivalent of bc4bbc42899a (which applied to Fedora).

narrow: don't compress the bundle2 when sending 'error:abort' This is similar to waht getbundle() does and also explicitly specifies that we should get a compressed bundle2 in normal cases when not sending 'error:abort'. Differential Revision: https://phab.mercurial-scm.org/D4934

push: add "remote" to 'repository changed while pushing' messages (issue5971) Differential Revision: https://phab.mercurial-scm.org/D4933
