match: strengthen visit_children_set invariant, Recursive means "all files"
My previous interpretation of "Recursive" was too relaxed: I thought it
instructed the caller to do something like this:
> you can stop calling `visit_children_set` because you'll need to descend into
> every directory recursively, but you should still check every file if it
> matches or not
Whereas the real instruction seems to be:
> I guarantee that everything in this subtree matches, you can stop
> querying the matcher for all files and dirs altogether.
The evidence to support this:
- the test actually passes with the stronger invariant, revealing no
exceptions from this rule
- the implementation of `visit_children_set` for `DifferenceMatcher`
clearly relies on this requirement, so it must hold for that not to
lead to bugs.
(Translations are optional)
#if gettext no-outer-repo
Test that translations are compiled and installed correctly.
Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:
$ LANGUAGE=pt_BR hg tip
abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)
[10]
Using a more accommodating encoding:
$ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado) (esc)
[10]
Different encoding:
$ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado) (esc)
[10]
#endif
#if gettext
Test keyword search in translated help text:
$ HGENCODING=UTF-8 LANGUAGE=de hg help -k Aktualisiert
Themen:
subrepos Unterarchive
Befehle:
pull Ruft \xc3\x84nderungen von der angegebenen Quelle ab (esc)
update Aktualisiert das Arbeitsverzeichnis (oder wechselt die Version)
#endif
Check Mercurial specific translation problems in each *.po files, and
tool itself by doctest
$ cd "$TESTDIR"/../i18n
$ "$PYTHON" check-translation.py *.po
$ "$PYTHON" check-translation.py --doctest
$ cd $TESTTMP
#if gettext
Check i18n cache isn't reused after encoding change:
$ cat > $TESTTMP/encodingchange.py << EOF
> from mercurial.i18n import _
> from mercurial import encoding, registrar
> cmdtable = {}
> command = registrar.command(cmdtable)
> @command(b'encodingchange', norepo=True)
> def encodingchange(ui):
> for encode in (b'ascii', b'UTF-8', b'ascii', b'UTF-8'):
> encoding.encoding = encode
> ui.write(b'%s\n' % _(b'(EXPERIMENTAL)'))
> EOF
$ LANGUAGE=ja hg --config extensions.encodingchange=$TESTTMP/encodingchange.py encodingchange
