Guake won't start due to incorrect SCHEMA_DIR

Guake Terminal 3.4.0 Python 3.6.5 Gentoo Linux

I just upgraded Guake from 3.3.2 to 3.4.0 and it is now failing to start because it can't load the GLib schema.

Guake not running, starting it

I tracked it down to ab7b44ab346803f5846eb2959011ffe2270b8153. If I undo this change, guake will start.

Broken:

>>> d = os.path.dirname(os.path.dirname(sys.modules["guake"].__file__))
>>> p = os.path.basename(os.path.abspath(os.path.join(d, "..")))
>>> print('%s\n%s' % (d, p))
/usr/lib64/python3.6/site-packages
python3.6

Works:

>>> d = os.path.dirname(sys.modules["guake"].__file__)
>>> p = os.path.basename(os.path.abspath(os.path.join(d, "..")))
>>> print('%s\n%s' % (d, p))
/usr/lib64/python3.6/site-packages/guake
site-packages

Was the intended change perhaps to change the next line from os.path.abspath(os.path.join(d, "..")) to os.path.dirname(d)?

The same problem in my ubuntu18.04. And tracked it down to ab7b44a can't help.

sudo make reinstall have this problem. sudo -H make reinstall work for me.

This problem also exists in FreeBSD. I have been working on updating the port, got it to compile, but it's complaining about the gschemas missing. It's looking in /usr/local/lib/python-3.6/site-packages/data (Why is it even looking there?)

[gsemet]

hi. how is package install on freebsd? make install is obviously debian oriented, so if you have more information on how python works on other systems I can rework it :)

[SparkyBluefang]

@y2kbadbug I'm assuming the FreeBSD problem is the exact same one I'm seeing on Linux, due to the change in ab7b44a. If you manually undo these changes on the installed paths.py I'm willing to be it will start working.

@gsemet Might I suggest moving the data, and po directories into the python module? That would simplify the path resolution and avoid needing to walk up and down the directory tree and hope you end up in the correct location.

def get_data_files_dir():
    return os.path.dirname(sys.modules["guake"].__file__)

As far as I can tell, the files in /usr/share/guake/ (or equivalent) are only referenced by guake at run time, so there dosn't appear to be a reason to install them outside of the python module.

[gsemet]

this is quite difficult to follow. pypi wheels "data" section is not well documented, so there is lot of latitude here. I think pypi install it into /usr/local/share/guake (to be cofnirmed). debian started packaging it into /usr/share/guake. I mimicked it to put it into /usr/local/share/guake in my make install. In my custom rebuild of pip install I kept this file, but it makes it very difficult to access to it using pkg_resource, which is being replaced.

So yet, maybe I'll rework it again to place it into the python module, at least this would simplify this mess. But having the resource in /usr/share/guake looked cool at the time :)

I created a separate ticket for FreeBSD support #1444

[eblis]

I have the same issue on Linux Mint 19.

[lucasbru]

Same issue on fedora 29

[mskrip]

Had the same issue on Arch. Realized I had both guake from Arch repos and from pip. Solved by uninstalling the pip version.

[drNoob13]

Your Guake installing from source was in conflict with your guake installed from pip. Uninstall the pip version would solve that for you.

Guake error throw upon starting:

Merged #1893 that may fix this, new version of guake coming soon so that the affected can confirm whether or not this is fixed. This will also be in latest git master, but compiling from source sends files to a different place which will make this work, but doesn't quite confirm that the issue is dealt with.
