Cura: [3.6.0] cura looks for image file in home dir, not /usr/share/cura/resources

[CapnKernel]

Application Version
3.6.0

Platform
Linux, Fedora 28. Self built, can recompile if you have suggestions

Printer
Ender 3 (but this problem isn't related to a particular printer)

Steps to Reproduce
Start cura in a terminal.

Actual Results
Stack trace (see below) while creating splash screen

Expected results
Splash screen

Additional Information

Strace shows that cura is trying to access /home/mjd/.local/share/cura/3.6/images/cura-icon-32.png:

stat("/home/mjd/.local/share/cura/3.6/images/cura-icon-32.png", 0x7ffe18d82fb0) = -1 ENOENT (No such file or directory)

It should be accessing /usr/share/cura/resources/images/cura-icon-32.png:

[mjd@xiaomao ~]$ ls -l /usr/share/cura/resources/images/cura-icon-32.png
-rw-r--r--. 1 root root 15000 Nov 13 01:47 /usr/share/cura/resources/images/cura-icon-32.png

If I cd into /home/mjd/.local/share/cura/3.6 and create a symlink from images to /usr/share/cura/resources/images, then Cura is able to start.

I've looked at UM/Resources.py. I think this should be looking in /usr/share/cura/resources, but I'm not sure of how to set UM.Resources.__data_storage_path to be /usr/share/cura/resources, or whether this is the right fix. Perhaps there needs to be a change to Uranium, and perhaps I need to pass /usr/share/cura/resources to Uranium at build time. Advice needed!

Hello @CapnKernel , I run cura from a local installation happily enough using this script (cura.sh) which I have in /opt/cura/bin.

````

!/bin/sh

this assumes that $0 is equal to $CURA_HOME/bin/cura.sh after symlinks have been resolved

CURA_BIN=$(dirname $(realpath $0))

CURA_HOME=$(realpath $CURA_BIN/..)

CURA_LIB=$CURA_HOME/lib

PATH=$CURA_BIN:$PATH

export PYTHONPATH=$CURA_HOME/lib/python3/dist-packages:$CURA_LIB/cura
export LD_LIBRARY_PATH=$CURA_LIB
export QT_PLUGIN_PATH=$CURA_LIB/plugins
export QML2_IMPORT_PATH=$CURA_LIB/qml

cura $@
````

[CapnKernel]

Hi @smartavionics. Thanks for your message. I can see that this will let you run Cura as a local install. I'd like to run Cura as a system-installed package, ie, any logged in user can run it. And for that to work, /bin/cura will have to look in /usr/share/cura/resources. (This is what happens with Fedora's cura package)

[smartavionics]

Ah, OK. Sorry, I can't really help with packaging.

[Ghostkeeper]

The data storage path is being set to $XDG_DATA_HOME or ~/.local/share/ if that environment variable is missing. Maybe you can start it with that environment variable adjusted?

Do you know if we need to improve this in the source code to be more adherent to standards?

[hroncok]

I suppose default icons are not what users should put it their homes, or are they?

[Ghostkeeper]

Ah, no, sorry. I was referring to Resources.__data_storage_path which is indeed where it stores data files, not where it loads it from.

The places where it looks should be the list of:

• $XDG_DATA_HOME/cura/4.0/resources
• (if not running from source) <executable>/../share/cura/resources
• (if running from source) ../resources relative to CuraApplication.py as well as Application.py

See also the function CuraApplication.__addExpectedResourceDirsAndSearchPaths.

[hroncok]

In Fedora, we have resources in /usr/share/cura/resources, the icon for example lives in /usr/share/cura/resources/images/cura-icon-32.png.

CuraApplication.py resides in /usr/lib/python3.7/site-packages/cura/CuraApplication.py.

Should I patch something to make this work? I never heard about problems with this, until I saw this issue.

[Ghostkeeper]

Because of the second place in my list, <executable>/../share/cura/resources I'd think it would work if your Python executable lives in /usr/bin. It would then look in /usr/bin/../share/cura/resources.

If you patch the Resources class to add some resources folder via Resources.addSearchPath then you could add an arbitrary extra directory.

[hroncok]

That'll be /usr/bin/cura, so yes, it should work.

[CapnKernel]

@Ghostkeeper, I'll do some more digging.

[CapnKernel]

I found the bug! It's in Uranium, UM/Application.py's Application.getInstallPrefix() method.

This bug will affect anyone who uses a Linux system where /bin is a symlink to /usr/bin (such as Fedora), _and_ the user has modified their PATH environment variable to have /bin before /usr/bin.

Within getInstallPrefix(), sys.executable is /usr/bin/python3, so sys.argv[0] is used.

In this case, running cura means sys.argv[0] will be /bin/cura, and getInstallPrefix() will return /. share gets appended to this (ie, /share/cura/resources), and naturally, looking for resources here fails.

If /bin _isn't_ in the PATH before /usr/bin, running cura means sys.argv[0] will be /usr/bin/cura, and getInstallPrefix() will return /usr. share gets appended to this (ie, /usr/share/cura/resources), and lookup of resources works.

To reproduce (on a machine where /bin is a symlink to /usr/bin, such as Fedora):

/bin/cura

This gives the unresponsive window and backtrace, whereas this works:

/usr/bin/cura

One fix for the problem is to add os.path.realpath() to the chain in getInstallPrefix(), which causes the /bin symlink to be followed:

     __instance = None   # type: Application

While most people won't have /bin in their PATH before /usr/bin, it's valid to do so, and Cura should still work. Please take my fix.

[Ghostkeeper]

Fantastic analysis actually! Thank you for investigating.

[hroncok]

Out of curiosity, @CapnKernel, why do you have /bin in PATH? At least why sooner than /usr/bin.

[CapnKernel]

@hroncok, I added it to my .bashrc in 1993 on a non-Linux system (/bin and /usr/bin were separate) and it's been there ever since! I've now taken it out (no longer needed eh!) but still, Cura shouldn't crash if invoked as /bin/cura.

(Of historical interest: Original Unix systems had/usr on a separate volume, which was mounted relatively late in the boot process. On such systems, all the binaries necessary to boot should be in /bin. That doesn't apply to Linux)

I'm happy for this issue to be closed, esp since it's now covered in an issue under Uranium. Thanks!

That's an old bashrc! Thanks for explaining.

it's an older .bashrc sir, but it checks out
