compat: back out a25343d16ebe (initialize LC_CTYPE locale on all Python ...) As Yuya Nishihara pointed out, setting LC_CTYPE changes the behavior of some str methods on Python 2.

curses: back out d2227d4c9e6b (do not initialize LC_ALL to user settings) The changeset was based on a25343d16ebe, which will be backed out, too. Another fix for the problem will be resubmitted to the stable branch.

test: redirect stderr so warning messages don't change output (issue6237) clone and commit race for the lock, and if commit has to wait more than a second it prints a warning to stderr. Since this is somewhat expected here, silence it. Differential Revision: https://phab.mercurial-scm.org/D8664

locks: expect repo lock, not wlock, when writing to .hg/strip-backup/ There should be no need for a working copy lock when creating (or reading) bundles in `.hg/strip-backup/` since they don't affect the working copy. I noticed this because we have an extension that tries to strip some revisions while holding only a repo lock. I guess we have no such cases in core, which seems a bit surprising. Maybe we always take a wlock at a higher level so the working copy is not updated while the target commit is being stripped. Differential Revision: https://phab.mercurial-scm.org/D8666

version: sort extensions by name in verbose mode External extensions can be assigned any name, but presumably most enabled extensions will be internal ones and having them sorted makes it easier to find specific ones if the list is long. The lists in `hg help extensions` are already sorted. Differential Revision: https://phab.mercurial-scm.org/D8671

crecord: stop trying to import wcurses The original import of crecord in 2008 already said "I have no idea if wcurses works with crecord...". The last reference to a Python package called wcurses is https://web.archive.org/web/20101025073658/http://adamv.com/dev/python/curses/. However, the Python package from there is called "curses" and not "wcurses". I didn’t find any evidence that it ever worked.

debian: support building a single deb for multiple py3 versions Around transitions from one python minor version to another (such as 3.7 to 3.8), the current packaging can be slightly problematic - it produces a `control` file that requires that the version of `python3` that's installed be exactly the one that was used on the build machine for the `mercurial` package, by containing a line like: Depends: sensible-utils, libc6 (>= 2.14), python3 (<< 3.8), python3 (>= 3.7~), python3:any (>= 3.5~) This is because it "knows" we only built for v3.7, which is the current default on my system. By building the native components for multiple versions, we can make it produce a line like this, which is compatible with 3.7 AND 3.8: Depends: sensible-utils, libc6 (>= 2.14), python3 (<< 3.9), python3 (>= 3.7~), python3:any (>= 3.5~) This isn't *normally* required, so I'm not making it the default. For those that receive their python3 and mercurial packages from their distro, and/or don't have to worry about a situation where the team that manages the python3 installation isn't the same as the team that manages the mercurial installation, this is probably not necessary. I chose the names `DEB_HG_*` because `DEB_*` is passed through `debuild` automatically (otherwise we'd have to explicitly allow the options through, which is a nuisance), and the `HG` part is to make it clear that this isn't a "standard" debian option that other packages might respect. Test Plan: 1. "nothing changed": - built a deb without these changes - built a deb with these changes but everything at the default - used diffoscope to compare, all differences were due to timestamps 2. "explicit is the same as implicit" (single version) - built a deb with everything at the default - built a deb with DEB_HG_PYTHON_VERSIONS=3.7 - used diffoscope to compare, all differences were due to timestamps 3. "explicit is the same as implicit" (multi version) - built a deb with DEB_HG_MULTI_VERSION=1 - built a deb with DEB_HG_PYTHON_VERSIONS=3.7 - used diffoscope to compare, all differences were due to timestamps 4. (single version, 3.7) doesn't work with python3.8 - `/usr/bin/python3.7 /usr/bin/hg debuginstall` works - `/usr/bin/python3.8 /usr/bin/hg debuginstall` crashes 5. (multi version, 3.7 + 3.8) - `/usr/bin/python3.7 /usr/bin/hg debuginstall` works - `/usr/bin/python3.8 /usr/bin/hg debuginstall` works Differential Revision: https://phab.mercurial-scm.org/D8642

curses: do not initialize LC_ALL to user settings (issue6358) 701341f57ceb moved the setlocale() call to right before curses was used. This didn’t fully solve the problem it was supposed to solve (locale-dependent functions, like date formatting/parsing), but only postponed it. Initializing LC_CTYPE seems to be sufficient for curses to work correctly. Luckily this is already done at interpreter startup on modern Python versions and, since recently, by Mercurial in the pycompat module in all other cases.

compat: initialize LC_CTYPE locale on all Python versions and platforms Previously, the LC_CTYPE locale was not initialized according to user settings on all Python versions (e.g. never on Python 2) and platforms (e.g. not on some Python < 3.8 on Windows). This broke e.g. non-ASCII filenames passed to the Subversion bindings on Python 2, resulting in error messages like "file:///tmp/a%C3%A4 does not look like a Subversion repository to libsvn version 1.14.0". The following command could be used to test this functionality. Adding it to the test suite would be pointless, as the locale is always set to "C" during test runs. @command(b'check_initial_codeset', norepo=True) def check_initial_codeset(ui): codeset1 = locale.nl_langinfo(locale.CODESET) locale.setlocale(locale.LC_ALL, '') codeset2 = locale.nl_langinfo(locale.CODESET) assert codeset1 == codeset2
