Travis build fails

[parinporecha]

Travis build for GTG fails because it is not able to import the module 'gi'.
Here's a bulid-log - https://travis-ci.org/getting-things-gnome/gtg/builds/22000561#L302

Here's the relevant question asked on SO - http://stackoverflow.com/questions/22748528/travis-ci-gobject-introspection

Travis uses virtualenv for Python tests. So, could it be possible that the python3-gi package installed globally before the build is not able to be imported inside the virtualenv ?
Relevant answer regarding virtualenv - http://stackoverflow.com/a/17800821

But since gir cannot be installed through pip, a possible fix would be adding its location to the virtual path - http://stackoverflow.com/a/12831223

Feel free to modify .travis.yml and try to make it work. I found couple repos with really similar config file and it works for them. :(

I've enabled importing system packages into virtualenv, that should not be the issue

Looks like Travis CI uses ubuntu 12.04 (maybe because of LTS), so we couldn't install python3 packages using apt-get. Also, GObject Introspection libraries aren't available on pypi, so we need to

• either add python3-gi's ppa to apt-get & then try to install it
• or download 'gi' module's tarball, compile it & move it with virtualenv's packages.

I'll test whether any of the above methods works.

@PARTP , apt-get is successfully able to install python3-gi. You can find it in the buildlog - https://s3.amazonaws.com/archive.travis-ci.org/jobs/22000562/log.txt

I've pasted below the relevant part -

@parinporecha, you're right. Packages via apt-get do get installed & are even imported with the help of system_site_packages.

• The problem is with gi._gi module. When I explored the gi package, there's no python module for _gi but a shared object file _gi.cpython-32mu.so for cpython implementation.
• I also set up a new Ubuntu 12.04 VM, just like Travis CI's worker & no error was thrown when I linked system-wide gi module to virtualenv & executed the same steps.

ibus-bogo-python seems to run those tests on Travis perfectly fine:

• .travis.yml
• Travis (tests are failing because of actual issues, not gi)

Thanks @izidormatusov for the example, the problem was caused by the combination of python 3.3 & Ubuntu 12.04 for shared object file _gi.cpython-32mu.so in gi package.
I should have understood the problem by noticing the python version on the Ubuntu 12.04 VM I set up.
