py3: whitelist another six passing tests Differential Revision: https://phab.mercurial-scm.org/D2230

narrowrepo: filter() is a generator on py3, wrap in list() Was at the top of Python 3 exceptions. Differential Revision: https://phab.mercurial-scm.org/D2229

narrowcommands: use pycompat.{bytes,str}kwargs Differential Revision: https://phab.mercurial-scm.org/D2228

debugcommands: mergestate version is an int, use %d on it Differential Revision: https://phab.mercurial-scm.org/D2227

progress: use %d to format ints instead of %s Due to behavioral changes between '% Ns' and '% Nd' this has some unfortunate extra dancing. I'm not sure of a better way to solve this problem. Differential Revision: https://phab.mercurial-scm.org/D2226

progress: determine padding width portably Differential Revision: https://phab.mercurial-scm.org/D2225

branchmap: wrap builtin exception in bytes for logging Differential Revision: https://phab.mercurial-scm.org/D2224

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.

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
