py3: fix test-remotefilelog-repack.t This is uglier, but more obviously correct in my opinion. I guess Python 3 doesn't hang on to the exception as long, which seems reasonable. Differential Revision: https://phab.mercurial-scm.org/D5781

tests: alter email `From` line to a value that's consistently parsed Python2: >>> email.header.decode_header('=?UTF-8?q?Rapha=C3=ABl=20Hertzog?= <hertzog@debian.org>') [('Rapha\xc3\xabl Hertzog', 'utf-8'), ('<hertzog@debian.org>', None)] Python3: >>> email.header.decode_header('=?UTF-8?q?Rapha=C3=ABl=20Hertzog?= <hertzog@debian.org>') [(b'Rapha\xc3\xabl Hertzog', 'utf-8'), (b' <hertzog@debian.org>', None)] So alter the input to an input that parses to the same result consistently. After skimming the relevant RFC (1342), I'm not sure if what we had was valid, or how I could modify it to be more consistent. Differential Revision: https://phab.mercurial-scm.org/D5769

diff: drop duplicate filter of copies by destination I'm pretty sure we don't need to filter copies by destination, at least since the previous patch. Differential Revision: https://phab.mercurial-scm.org/D5790

diff: use match.intersectmatchers() Differential Revision: https://phab.mercurial-scm.org/D5789

tests: convert ParseError arguments to str on Python 3 Arguments internally are bytes. Printing the exception on Python 3 will include b'' prefixes. This test file uses a .out file, which doesn't support conditional output. The easiest way to get this to pass on Python 3 is to normalize the exception before printing so there are no b'' prefixes. Differential Revision: https://phab.mercurial-scm.org/D5793

tests: quote $PYTHON for py3 support on Windows

py3: byteify the --retest path of run-tests.py

subrepo: clean up lingering bytes/str issues in svn support Path encoding is a little suspect in here, but it's not worse than it was when we were on Python 2 only. Subversion subrepo tests now pass in Python 3. Differential Revision: https://phab.mercurial-scm.org/D5774

tweakdefaults: set ui.relative-paths instead of command.status.relative Differential Revision: https://phab.mercurial-scm.org/D5775

status: introduce higher-level ui.relative-paths The existing commands.status.relative trumps the new config. We need to keep the existing config around for compatibility. However, I don't think we need to introduce similar command-specific options for other commands when they learn to respec ui.relative-paths. Differential Revision: https://phab.mercurial-scm.org/D5746

status: extract helper for producing relative or absolute path for UI I put the helper in scmutil so it can be used by most modules. I would have put it in utils.pathutil, but I think that's supposed to be unaware of repos. Differential Revision: https://phab.mercurial-scm.org/D5745

tags: avoid generating commit for an already deleted tag (issue5752) `$ hg tag --remove <tagname>` will keep on generating commits regardless of checking whether the tag is deleted or not. I added a a fix for `global` tags by aborting if `nullid` is already mapped to the tag that is to be deleted. Differential Revision: https://phab.mercurial-scm.org/D5780

watchman: detect nested mercurial repositories and abort Disable fsmonitor on nested mercurial repositories. Only depth one repositories are detected at the moment. Differential Revision: https://phab.mercurial-scm.org/D5587

watchman: add verbose config knob This new config knob allows to silent watchman log and warning messages when watchman is unavailable. Differential Revision: https://phab.mercurial-scm.org/D5586

extdiff: add --per-file and --confirm options The new options lets the user control how the external program is run. By default, Mercurial passes the 2 snapshot directories as usual, but it can also run the program repeatedly on each file's snapshot pair, and optionally prompt the user each time.
