subrepo: avoid calculating subrepo prefix twice for cat() (API) Differential Revision: https://phab.mercurial-scm.org/D5881

py3: make sure __repr__ returns str No test fails but I found it while debugging test-commit-interactive-curses.t failure. # skip-blame because just r'' prefix Differential Revision: https://phab.mercurial-scm.org/D5878

py3: use bytes.startswith() instead of comparing with bytes[0] This is because bytes[0] will return the ascii value and comparison will fail. This makes test-commit-interactive-curses.t pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5879

match: remove unused "exact" argument (API) It seems that all callers use match.exact() instead of match.match(exact=True). Differential Revision: https://phab.mercurial-scm.org/D5919

tests: replace match.match(exact=True) by match.exact() Differential Revision: https://phab.mercurial-scm.org/D5918

patch: accept second matcher that applies only to copy sources (API) See previous patch for motivation. Differential Revision: https://phab.mercurial-scm.org/D5893

patch: let caller pass in root-filtering matcher (API) The --root option to `hg diff` does two things: * Shows paths relative to the given root * Filters paths by the given root, including copy sources The root argument is passed through down to patch.diff(). I feel like we can make patch.diff() more generic by not passing down the root argument, but instead pass: * A function for taking a repo-relative path and printing it. I want to reuse this for showing cwd-relative paths later. This is the actual motivation for this patch. * A matcher that's already been filtered by the root argument * A second matcher that filters the copy sources This is one step towards that.

patch: pass in context objects into diffhunks() (API) It's a pretty low-level function and having the contexts in patch.diff() makes future patches easier. Differential Revision: https://phab.mercurial-scm.org/D5891

convert: handle exec bit removal while converting to svn Subversion `putcommit` method checks original file's executablity to decide if executable property should be removed from svn. It is checked right after writing file contents. Content writing is implemented using `vfs.write` and vfs seems to remove exec bit, at least in some cases. This leads to executability checks being ineffective. If cset contains only this ignored exec bit removal, conversion stops with an error, because it fails to to compose svn commit properly. This fix moves exec bit checking so that it's performed before dumping file contents. Added test to check executable bit removal.

convert: handle empty intial commits while converting to svn Svn commit generation code skips empty commits, returning the parent. Skipping the root commit must return None instead. Added test to check skipping of empty commits.
