parser: stabilize output of prettyformat() by using byte-safe repr() The format of leaf nodes is slightly changed so they look more similar to internal nodes.

py3: fix repr(util.url) to return system string This is required on Python 3.

py3: use bytes[n:n + 1] to get bytes in templater._parsetemplate()

py3: fix type of attribute name in smartset.py

py3: fix mixed bytes/unicode in revsetlang._aliassyminitletters

py3: fix type of regex literals in subrepo.py

py3: replace bytes[n] with bytes[n:n + 1] in patch.py where needed

py3: fix type of regex literals in patch.py

revset: optimize "draft() & ::x" pattern The `draft() & ::x` type query could be common for selecting one or more draft feature branches being worked on. Before this patch, `::x` may travel through the changelog DAG for a long distance until it gets a smaller revision number than `min(draft())`. It could be very slow on long changelog with distant (in terms of revision numbers) drafts. This patch adds a fast path for this situation, and will stop traveling the changelog DAG once `::x` hits a non-draft revision. The fast path also works for `secret()` and `not public()`. To measure the performance difference, I used drawdag to create a repo that emulates distant drafts: DRAFT4 | DRAFT3 # draft / PUBLIC9999 # public | PUBLIC9998 | . DRAFT2 . | . DRAFT1 # draft | / PUBLIC0001 # public And measured the performance using the repo: (BEFORE) $ hg perfrevset 'draft() & ::(DRAFT2+DRAFT4)' ! wall 0.017132 comb 0.010000 user 0.010000 sys 0.000000 (best of 156) $ hg perfrevset 'draft() & ::(all())' ! wall 0.024221 comb 0.030000 user 0.030000 sys 0.000000 (best of 113) (AFTER) $ hg perfrevset 'draft() & ::(DRAFT2+DRAFT4)' ! wall 0.000243 comb 0.000000 user 0.000000 sys 0.000000 (best of 9303) $ hg perfrevset 'draft() & ::(all())' ! wall 0.004319 comb 0.000000 user 0.000000 sys 0.000000 (best of 655) Differential Revision: https://phab.mercurial-scm.org/D441

phabricator: add a config to use curl for communication Not sure why, but I got `phabsend` hang on work network pretty frequently. The traceback indicates it hangs at `_sslobj.do_handshake()`: File "mercurial/sslutil.py", line 404, in wrapsocket sslsocket = sslcontext.wrap_socket(sock, server_hostname=serverhostname) File "/usr/lib/python2.7/ssl.py", line 363, in wrap_socket _context=self) File "/usr/lib/python2.7/ssl.py", line 611, in __init__ self.do_handshake() File "/usr/lib/python2.7/ssl.py", line 840, in do_handshake self._sslobj.do_handshake() I had tried adding `timeout` in various places but they seem not effective. It seems easier to just allow shelling out to `curl` with retry and timeout flags. This could also be helpful for people with an older Python installed without modern security (SNI).
