The fact that we aren't dealing with the Django source tree anymore
allows us to drop several tearDown()/addCleanup() calls that were
concerned with removing apiece files/dirs/symlinks created by test
cases, as we are covered by the removal of the parent temporary tree
anyways.
Thanks Tim Graham for advice and review.
This allows makemessages/compilemessages tests in `test_extraction.py`
and `test_compilation.py` to actually run isolated from each other
(unaffected by stray FS objects left by cleanup actions failures, debug
sessions, etc.) and to take advantage of the parallel tests execution
feature like most of the Django test suite.
`test_percents.py` gets slightly refactored to not inherit from the new
machinery which sets up every test case to copy and run under a
temporary tree.
Made it consistently read the PO file, decode its contents and then
check for the non-breaking space Unicode code point.
Previously we were erroneously skipping the interpretation of what we
read as UTF-8 text.
This was causing the test to fail on Windows with Python 3.5.
Changed the way makemessages invokes xgettext from one call per
translatable file to one call per locale directory (using --files-from).
This allows to avoid https://savannah.gnu.org/bugs/index.php?35027 and,
as a positive side effect, speeds up localization build.
Refactored tests to use a sample project.
Updated extraction:
* Removed special handling of single percent signs.
* When extracting messages from template text, doubled all percent signs
so they are not interpreted by gettext as string format flags. All
strings extracted by gettext, if containing a percent sign, will now
be labeled "#, python-format".
Updated translation:
* Used "%%" for "%" in template text before calling gettext.
* Updated {% trans %} rendering to restore "%" from "%%".
Make sure PO catalog text fetched from gettext programs via standard
output isn't corrupted by mismatch between assumed (UTF-8) and real
(CP1252) encodings. This can cause mojibake to be written when creating
or updating PO files.
Also fixes#23311.
Thanks to contributor with Trac nick 'danielmenzel' for the report,
excellent research and fix.
Changed the handling of extensions to be used for gettext. Now
obeying the --extension argument. find_files now only find the
given or default extensions and puts only these in the
TranslatableFiles. As a result there are no more confusing messages
for filetypes (extension) not handled by makemessages.
