chg: force-set LC_CTYPE on server start to actual value from the environment
Python 3.7+ will "coerce" the LC_CTYPE variable in many instances, and this can
cause issues with chg being able to start up. D7550 attempted to fix this, but a
combination of a misreading of the way that python3.7 does the coercion and an
untested state (LC_CTYPE being set to an invalid value) meant that this was
still not quite working.
This change will cause differences between chg and hg: hg will have the LC_CTYPE
environment variable coerced, while chg will not. This is unlikely to cause any
detectable behavior differences in what Mercurial itself outputs, but it does
have two known effects:
- When using hg, the coerced LC_CTYPE will be passed to subprocesses, even
non-python ones. Using chg will remove the coercion, and this will not
happen. This is arguably more correct behavior on chg's part.
- On macOS, if you set your region to Brazil but your language to English,
this isn't representable in locale strings, so macOS sets LC_CTYPE=UTF-8. If
this value is passed along when ssh'ing to a non-macOS machine, some
functions (such as locale.setlocale()) may raise an exception due to an
unsupported locale setting. This is most easily encountered when doing an
interactive commit/split/etc. when using ui.interface=curses.

A python hook for "hg fix" that prints out the number of files and revisions that were affected, along with which fixer tools were applied. Also checks how many times it sees a specific key generated by one of the fixer tools defined below. $ cat >> $TESTTMP/postfixhook.py <<EOF > import collections > def file(ui, repo, rev=None, path=b'', metadata=None, **kwargs): > ui.status(b'fixed %s in revision %d using %s\n' % > (path, rev, b', '.join(metadata.keys()))) > def summarize(ui, repo, replacements=None, wdirwritten=False, > metadata=None, **kwargs): > counts = collections.defaultdict(int) > keys = 0 > for fixername, metadatalist in metadata.items(): > for metadata in metadatalist: > if metadata is None: > continue > counts[fixername] += 1 > if 'key' in metadata: > keys += 1 > ui.status(b'saw "key" %d times\n' % (keys,)) > for name, count in sorted(counts.items()): > ui.status(b'fixed %d files with %s\n' % (count, name)) > if replacements: > ui.status(b'fixed %d revisions\n' % (len(replacements),)) > if wdirwritten: > ui.status(b'fixed the working copy\n') > EOF Some mock output for fixer tools that demonstrate what could go wrong with expecting the metadata output format. $ printf 'new content\n' > $TESTTMP/missing $ printf 'not valid json\0new content\n' > $TESTTMP/invalid $ printf '{"key": "value"}\0new content\n' > $TESTTMP/valid Configure some fixer tools based on the output defined above, and enable the hooks defined above.
