hg: move share._getsrcrepo into core The fact we were calling this from extensions was a sign that it should live in core. We were also able to remove some extra attribute aliases from the share extension. Differential Revision: https://phab.mercurial-scm.org/D2200

tests: glob over line number Differential Revision: https://phab.mercurial-scm.org/D2199

remotenames: add three new revsets related to remotenames This patch adds three new revsets 'remotenames', 'remotebookmarks' and 'remotebranches' which will return changesets which have remotenames, remotebookmarks and remotebranches on them respectively. The remotenames revset exist in hgremotenames extension and is moved from there whereas rest of the two revsets are introduced in this patch. hgremotenames: https://bitbucket.org/seanfarley/hgremotenames Differential Revision: https://phab.mercurial-scm.org/D2002

convert: fix line ending of mapfile and commit.desc file Follows up 42a393ea56d2. CRLF vs LF doesn't really matter as we do strip() or rstrip() on read, but mixing them isn't nice. So let's restore the old behavior. I don't know whether CVS/Root, CVS/Repository, and ~/.cvspass are written in native line ending, so I leave them read as binary files.

py3: port string formatting `skipped` is a set of integer revs here. So cast integers to strings using %d. None doesn't cast to an empty string on Python 3. So use '' explicitly. Differential Revision: https://phab.mercurial-scm.org/D2146

bdiff: write a native version of splitnewlines ./hg perfunidiff mercurial/manifest.py 0 --count 500 --profile before: ! wall 0.309280 comb 0.350000 user 0.290000 sys 0.060000 (best of 32) ./hg perfunidiff mercurial/manifest.py 0 --count 500 --profile after: ! wall 0.241572 comb 0.260000 user 0.240000 sys 0.020000 (best of 39) so it's about 20% faster. I hate Python. I wish we could usefully write this in Rust, but it doesn't look like that's realistic without using the cpython crate, which I'd still like to avoid. Differential Revision: https://phab.mercurial-scm.org/D1973

label: enforce the lack of leading or trailing white space In practice, all commands create label are currently striping external white space. Let us enforce this logic at a lower level before starting to rely on it elsewhere.

buildrpm: bump bundled docutils version to 0.14 when building for centos{5,6} when building rpm packages for centos 5 and 6, we bundle a mercurial-specific version of docutils in /opt/python-hg/lib/python2.7/site-packages/docutils Let's bump the embedded docutils version from 0.12 (released in 2014) to 0.14 (latest as of today)

buildrpm: bump bundled python version to 2.7.14 when building for centos{5,6} when building rpm packages for centos 5 and 6, we bundle a mercurial-specific version of python 2.7 in /opt/python-hg Let's bump the embedded python version from 2.7.10 (released in 2015) to 2.7.14 (latest as of today)

merge: invoke scmutil.fileprefetchhooks() prior to applying updates This moves the file list calculation into core, so other extensions don't need to duplicate it.

revert: drop the remnant of the prefetchfiles hook

cat: migrate to the fileprefetch callback mechanism

archive: migrate to the fileprefetch callback mechanism

lfs: migrate to the fileprefetch callback mechanism

cmdutil: convert the prefetchfiles() hook to a callback mechanism (API) Yuya suggested a list of callbacks instead of function wrapping. This means that one extension can't block another from processing the list. .. api:: File prefetching is now handled by registering a callback with scmutil.fileprefetchhooks.

test-narrow: partially stabilize on Windows test-narrow-strip.t is still broken. I don't see any feature condititionals, so it might be an actual problem.

util: convert traceback-related sysstrs to sysbytes in getstackframes With this change, test-devel-warnings.t passes except for differences in how ProgrammingError is formatted and one mysterious traceback inside of transaction.__del__. Differential Revision: https://phab.mercurial-scm.org/D2212

util: format line number of stack trace using %d Required on Python 3, functional on Python 2. Differential Revision: https://phab.mercurial-scm.org/D2211

util: call warnings.warn() with a sysstr in nouideprecwarn This preserves nouideprecwarn wanting a bytes, which is consistent with the rest of hg. Differential Revision: https://phab.mercurial-scm.org/D2210

ui: convert stack traces to sysbytes before logging They're coming back as unicodes, so sysbytes seems like the best we can do. This is like D2171 and D2172, but those fail on Python 2.7.5 (seriously!), so this is my version of the same change. I actually wrote this before reviewing those, then discarded it, then came back to it after finding out 2.7.5 is a silly place. Differential Revision: https://phab.mercurial-scm.org/D2209

ui: use pycompat.bytestr() to get a bytes-repr of config default We don't know what type we'll get here, so we need something that'll behave like a repr without returning a unicode. Differential Revision: https://phab.mercurial-scm.org/D2208

py3: convert traceback representation to bytes when logging Python's APIs should return a system string. We want to use bytes for logging. So convert the traceback to bytes before sending it to the logger. Differential Revision: https://phab.mercurial-scm.org/D2176

mail: import email.utils not email.Utils email.Utils was renamed to email.utils in Python 2.5. But it appears at some point before Python 2.7 (possibly 2.5) email.Utils was aliased to the new home. So email.utils should be safe for all versions of Python we support. Differential Revision: https://phab.mercurial-scm.org/D2168

py3: cast character set to bytes The returned value from this function is eventually fed into email.charset.Charset.__init__. However, the standard library appears to handle both string types in Python 2 and 3. So there shouldn't be any problem returning a bytes here. Differential Revision: https://phab.mercurial-scm.org/D2167

py3: cast decode() argument to system string The actual types here may be mixed due to string literals and variables from other modules. So a cast is necessary. Differential Revision: https://phab.mercurial-scm.org/D2166

py3: avoid changing dictionary during iteration dict.items() and friends are iterators/views in Python 3. You aren't allowed to mutate the underlying dictionary when iterating on these views. So iterate over a copy of things. Differential Revision: https://phab.mercurial-scm.org/D2164

py3: use raw string for key in **kwargs Otherwise Python 3 is unhappy. We only set a single key here. So I don't think pycompat.strkwargs() is necessary. Differential Revision: https://phab.mercurial-scm.org/D2163

py3: preserve chunks as an iterable of bytes patch.diffstat() returns a bytes. util.chunkbuffer() expects an iterable of bytes. Feeding it a single bytes instance on Python 3 will iterate the characters as integers. This blows up util.chunkbuffer. Differential Revision: https://phab.mercurial-scm.org/D2162
