D14779: Fix 'kformattest fails with installed kcoreaddons language package'

  Personally i would include (and use) a fake translation as part of the tests 
and then it would just evaluate to the actual result, i.e.
  
QCOMPARE(format.formatSpelloutDuration(361), QStringLiteral("1 
hour(s)"));
  
  would end up being
  
QCOMPARE(format.formatSpelloutDuration(361), QStringLiteral("1 hour"));
  
  because we're using the "fake" translation.
  
  But i understand that is much more work and this makes the test pass already, 
so if noone disagrees i think this is good enough :)

  You have remembered that in this case the loader created by 
ecm_create_qm_loader(kcoreaddons_QM_LOADER kcoreaddons5_qt) must be adjusted to 
find this - not installed - fake translation by default ?

  I think that in the test we just need to call
  
bool QCoreApplication::installTranslator(QTranslator *translationFile)
  
  with the location of the fake translation and since newest location is tried 
first it should overwrite the one from the ecm loader.

  According to 
http://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/kernel/qcoreapplication.cpp#n1985
 new translators are prepended - not overwritten. Not sure if a missing 
translation in the latest file added would be search in the previous 
translators.
  
  To  understand you correctly: You really are thinking about generating  a qm 
file  from the kcoreaddons lib source with gettext containing real translations 
 added with lokalize or similar to avoid this issue ?

  So exactly what i said, the newly installed translator gets used first

  Why would it be missing?

  I am not sure what is "this issue", but what we need to do is just copy the 
english translation from the tarball to here and make sure it's used when the 
test is run.

  With the drawback that the qm file need to be generated on each build and the 
po file needs to be updated on any translations change in the test  app
  
  BTW: I tried your approach by
  
  1. downloaded po file from 
https://websvn.kde.org/trunk/l10n-kf5/en/messages/frameworks/kcoreaddons5_qt.po?revision=1522662&view=markup
  2. did run lrelease on that file and placed it into kcoreaddons source dir as 
kcoreaddons5_qt.qm
  3. added to top level CMakelists.txt
  
  `add_definitions(-DCMAKE_SOURCE_DIR="${CMAKE_SOURCE_DIR}")`
  
  3. add to autotests/kformattest.cpp
  
void KFormatTest::initTestCase()
{
QLocale::setDefault(QLocale::C);
QTranslator *l = new QTranslator();
l->load(QStringLiteral(CMAKE_SOURCE_DIR "/kcoreaddons5_qt.qm"));
QCoreApplication::installTranslator(l);
}
  
  without kcoreaddons-lang package installed the test case returns on a system 
with installed de_DE

  Can you please replace your setLocale call in initTestCase for
  
  void initLocale()
  {
  
setenv("LC_ALL", "en_US.utf-8", 1);
  
  }
  Q_CONSTRUCTOR_FUNCTION(initLocale)
  
  This should make it work (or at least it does here)

  Just recognized  general issues in kcoreaddons translation, which need to be 
fixed before - please accept D14940 .
  
  Then I will rebase this patch and check your suggestion.

  Use qputenv instead of setenv.

[Ralf Habacker]

  Thanks for this pointer - with this setting the german translation is not 
fetched anymore.
  
  But there is still the question open how to deal with plurals with and 
without installed kcoreaddons language package.
  
  I guess running tests without kcoreaddons-lang installed will be performed at 
KDE CI and running tests with kcoreaddons language package mainly happens on 
developers desktop systems, where KF5 is installed and a developer is working 
on kcoreaddons.
  
  From what I read on Qt doc ui string with plurals always need to use a 
translation string with "%n millisecond(s)"  (cleaned with  D14940 
), but in the test code there are two cases
  
QCOMPARE(format.formatDecimalDuration(1 * MSecsInDay + 10 * MSecsInHour, 
3), QStringLiteral("1.417 days"));
  
  This one requires to have a translation installed, which translates "day(s)" 
to "days"
  
  and this one
  
QCOMPARE(format.formatDecimalDuration(10), QStringLiteral("10 
millisecond(s)"));
  
  This fails with a translation installed because an installed english 
translation translates this to "10 milliseconds"
  
  How to proceed ?

  A further look into the windows implementation of the qm loader part 
(https://cgit.kde.org/extra-cmake-modules.git/tree/modules/ECMQmLoader.cpp.in#n65)
 shows that the language is fetched from `QLocale::system() `
  
  QLocale::system() is initiated on unix os from LC_ALL and friends 
(http://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/tools/qlocale_unix.cpp#n75),
 which could be changed with the qputenv call.
  
  But on Windows the system locale is fetched from the current user locale 
(http://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/tools/qlocale_win.cpp#n172),
 which could not be changed temporary by the test app.
  
  To have a cross platform solution I think it is really required to disable 
loading translations in this test.  If QLocale::C could not be used for that 
(Albert mentioned that)  an auxiliary function provided by the qmloader is 
required for that.
  I'm going to file a related review request.
