branchcache: skip entries that are topological heads in the on disk file
In the majority of cases, topological heads are also branch heads. We have
efficient way to get the topological heads and efficient way to retrieve
their branch information. So there is little value in putting them in the branch
cache file explicitly. On the contrary, writing them explicitly tend to create
very large cache file that are inefficient to read and update.
So the branch cache v3 format is no longer including them. This changeset focus
on the format aspect and have no focus on the performance aspect. We will cover
that later.
(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
