App Claims Files Are Missing (They're Not)

1

I was able to get my initial flatpak project running (the Flatpak Amulet Minecraft Map Editor), but I noticed that it was missing textures, so I’ve attempted to add the missing things by copying them from the original Python install of Amulet, however, despite the files being there according to the debug shell:

[/app/lib/python3.11/site-packages/minecraft_model_reader/api/resource_pack/java/java_vanilla_fix/assets/minecraft/textures/block] ls -Fla

-rw-r--r-- 3 evilsupahfly evilsupahfly  927 Dec 31  1969 water.png

The terminal output indicates the textures are missing:

How do I fix this?

You should share your Manifest, so People can help you

What do you mean by “debug shell”? Usually the files inside the sandbox are not owned by your user.

What is inside the sandbox if you run it directly via flatpak:

flatpak run --command=ls io.github.evilsupahfly.amulet-flatpak -al /app/lib/python3.11/site-packages/minecraft_model_reader/api/resource_pack/java/java_vanilla_fix/assets/minecraft/textures/block/

By “debug shell” I mean I did this:

flatpak run --devel --command=sh --system-talk-name=org.freedesktop.login1 io.github.evilsupahfly.amulet-flatpak

And systematically checked each directory down the path listed to be sure it was present.

I’ll post the manifest when I get home.

This could be because in an effort to fix the missing textures, I gzipped them from the original Python package and added the .tar.gz to my project as an extra local file, which gets unzipped to the specified location.

I should know better by now too. The question is incomplete (usually) without the manifest. :sweat_smile: :man_facepalming:

This is my primary manifest:

id: io.github.evilsupahfly.amulet-flatpak
name: Amulet Map Editor
runtime: org.freedesktop.Platform
runtime-version: '23.08'
sdk: org.freedesktop.Sdk

  - --share=ipc
  - --socket=fallback-x11
  - --socket=wayland
  - --filesystem=home:create

  - --env=OPENGL_VERSION=3.3
  - --env=OPENGL_LIB=/usr/lib/x86_64-linux-gnu/libGL.so

modules:
  - shared-modules/glew/glew.json
  - shared-modules/glu/glu-9.json
  - pip_gen.yaml
  - resource_pack/resource_pack.yaml

This is pip-gen.yaml which was generated automagically by flatpak-pip-generator based on the Amulet project’s requirements.txt:

This is the newest addition - my attempt to fix the missing textures, which hasn’t actually fixed anything, resource_pack.yaml:

name: resource_pack
build-commands:
  - >-
    set -e
    install -Dm 0755 minecraft_model_reader.tar.gz -t ${FLATPAK_DEST}/lib/python3.11/site-packages/
buildsystem: simple
sources:
  - type: file
    path: ../resource_pack/minecraft_model_reader.tar.gz
  - type: script
    dest: '${FLATPAK_DEST}/lib/python3.11/site-packages/'
    commands:
      - tar -xzf ${FLATPAK_DEST}/lib/python3.11/site-packages/minecraft_model_reader.tar.gz -v -C ${FLATPAK_DEST}/lib/python3.11/site-packages/
      - rm -f ${FLATPAK_DEST}/lib/python3.11/site-packages/minecraft_model_reader.tar.gz

My original project didn’t include resource_pack.yaml because that’s supposed to be included with Amulet’s Python source, and which works fine when Amulet is installed directly through PIP. However, when built by the flatpak builder, Amulet can’t find - or doesn’t recognize - the textures, so I tried to add them manually after the fact.

This:

I had planned to rebuild the project from scratch again, but this time without the resource pack extra I made, and compare the results, which I’ll reply with as soon as I have.

In the meantime, I’m just wondering why it works when installed (in a Python VENV) with PIP and doesn’t work when made into a Flatpak which - based on the manifest output from flatpak-pip-generator - appears to me like it does all the same things with PIP, but inside the flatpak sandbox.

Update:

I rebuilt the package without my resource_pack call, reinstalled the Amulet flatpak, and the missing textures are still an issue, so I re-ran ls inside the sandbox, but this time I called flatpak with -vv to see if I could get an idea of what’s going on and why.

Output exceeded character limit for posts, so I’ve posted it as a snippet on GIST.

I see quite a few [x] is not a symlink messages, but I don’t know if that’s normal. Amulet has no trouble getting RW access to the Minecraft saves in my $HOME so it must not be that big a deal.

My work-fried, under-slept self just realized that the missing textures are in minecraft-resource-pack which is already supposed to be included in the project, having been pulled in from requirements.txt:

versioneer
meson-python
glad
pyopengl
PyOpenGL-accelerate
numpy
lz4
amulet-core
amulet-map-editor
amulet-leveldb
amulet-nbt
minecraft-resource-pack

So now I’m REALLY confused about why the textures aren’t loading!

**Edit: This is verifiable by checking pip_gen.yaml in my earlier post.

8

Previously, I was building and installing from a local source. So I used the workflow for bilelmoussaoui/flatpak-github-actions to build the Amulet flatpak in my GIT repository instead, and the flatpak built by the workflow is also having these missing texture issues. Can somebody please explain to me what I’m doing wrong?
:face_with_spiral_eyes:

I don’t know Python enough so I can’t really help. There are a lot of Python applications on Flathub so I don’t think that there’s a general issue, your application somehow doesn’t like the environment Flatpak is providing. Did you check if any other files are missing which could result in the errors?

To debug this further, you can try building with online support (this is not allowed on Flathub & therefore everything is usually downloaded for an offline build).

I think this should be a template you can use, but there could be mistakes I made (I did not test the snippet).

modules:
  - shared-modules/glew/glew.json
  - shared-modules/glu/glu-9.json
  - name: application
    build-commands:
      - pip3 install --prefix=${FLATPAK_DEST} <OPTIONS> <PACKAGE_NAME>
      - …
    buildsystem: simple
    build-options:
      build-args:
        - --share=network

And maybe you should remove access to the home dir (–filesystem=home) when testing, just to be sure that nothing from your development system is interfering.

So, the package is being installed, and both the .png images and the .JSON are present in their expected locations. Unfortunately, I can’t disable HOME access while testing because I need to be able to load a Minecraft world to be sure Amulet is working.

Currently, I’m looking at trying to debug the model/texture module to see what’s happening under the hood, but every time I change something, it crashes.

The template, however, I’ll take for a test drive after work tonight.

Sorry I took so long. I had a metric f*ck-tonne of tech support issues to resolve for friends and family all at once, around my normal job hours so this got pushed to the back burner for a while.

Anyways, after I rebuilt the flatpak from scratch - now with added debugging features - and tried again, I ran it with Flatpak’s internal version of PDB. The results are posted in this GIST but be warned - it’s sixty five thousand seven hundred and something lines long.

As far as I can tell, the .png files are actually being loaded properly. Running through PDB doesn’t really indicate why they’re not loading in the Flatpak environment. The error reported is not that the files weren’t found, only that they couldn’t be used. Also unclear is if the problem lies with the .JSON files or the .PNG files. Either way it’s a mystery since Amulet is able to download the official texture pack from the Minecraft servers and everything else shows up - bedrock, stone, sand, etc - meaning that .PNG and .JSON management within Amulet works just fine.

So… Is this a Flatpak issue or a Python issue?

12

So, this is still happening. The original dev doesn’t know why either because the app works just fine when installed through PIP in VENVs for Python 3.9 all the way up to 3.12.

I’ve allowed the app persistent access:

  - --filesystem=home:persistent
  - --filesystem=~/.cache:persistent

And having sorted out my metadata issues, I’m back to this little issue.

So once again, I ran a shell inside the flatpak:

flatpak-builder --run amulet-flatpak_build_dir io.github.evilsupahfly.amulet_flatpak..yaml sh

And I went down into the directories for the assets:

/app/lib/python3.12/site-packages/minecraft_model_reader/api/resource_pack/java/java_vanilla_fix/assets/minecraft/textures/block/

And I listed the contents of the directory and sure enough, they’re all present. I’m hoping somebody “fluent” in both Flatpak and Python can tell me what’s going on here. For the Python people, all paths within Amulet are relative to it’s install location, with the exception of files and folders it needs from the user’s $HOME (like .minecraft).

13

I suppose the biggest question I have would be how the Python environment inside the Flatpak is different from the one in my VENV, aside from being Read Only, despite being the same version (3.12.6).

14 
KeyError: '/app/lib/python3.12/site-packages/minecraft_model_reader/api/resource_pack/java/java_vanilla_fix/assets/minecraft/textures/block/water.png'

I can’t say that I exactly get what’s happening when the files are loaded, but doesn’t this error say, rather than the file is not found, that the value in the Map is missing or under a different key? Have you checked what’s put into the Map?

15

As far as I know, the map is generated on the fly by reading .PNG files from one folder, and .JSON files from a different one, then matching them by name, using a deepcopy to construct the new compound list from the two individual components, meaning as long as both water.json and water.png exist, it should be fine.

All this works flawlessly when installed in a normal Python virtual environment with PIP, yet when running as a Flatpak, “water” and “lava” always fail.

Also, as far as I know, all paths are relative to Amulet’s install location, so it shouldn’t matter that it’s “Flatpak Python” or “Normal Python”.

The complete model reader API is here, if you’re fluent in Python and are curious.

16

After much tediousness, I still couldn’t narrow down why the textures weren’t loading properly so I just brute forced it by adding this:

if texture_path not in self._texture_is_transparent:
    log.warning(f"Texture path not found: {texture_path}. Defaulting to non-transparent.")
    self._texture_is_transparent[texture_path] = (0, False)  # Default to non-transparent if not found

– (Modified Minecraft Model Reader)

Problem solved, textures loading. The .JSON files were all where they were supposed to be, and the .PNG files were all right where they belonged too, and that’s the only reason this seems to work. As for why this ran fine as a “proper desktop app” but not as a Flatpak is still a mystery to me. For now, though, this work-around does the trick.
