Minor problem with permissions and cygwin ~/.cache folder on windows

Hi, first of all congrats for the project. I really like it.
I had started a complete desktop with x11docker in Ubuntu without problems. In Windows I'm using xwin in cygwing installed.
When I use x11docker for the first time, it works correctly, problems start when I try to run x11docker after that first try.
Some files created at '~/.cache' (C:\cygwin64\home\<username>\.cache\ in Windows) are created with some weird permissions. The output of x11docker is this:
x11docker note: Using X server option --xwin

  to the X server. If no application window appears, but no obvious error
  is shown, please check your firewall settings. Compare issue #108 on github.

I've tried to delete these files as admin, and the unique way I've been able to delete them was starting windows in safe mode and delete it with the file explorer.
After removing these files, the first time you start x11docker again it works fine.

Okay I see that stopping docker in windows let me remove that cached files.

Thank you for reporting this!
That is really weird.
Even if the file store.info is somehow left after terminating x11docker instead of being deleted, x11docker would not use it again. x11docker always creates a new cache folder with a different number on startup.
And store.info is created with file access permission 666 (everyone can read and write). Should not matter in Cygwin, though.
I'll investigate.

Okay I see that stopping docker in windows let me remove that cached files.

That is an important hint.
Can you check if the container is still running after x11docker has terminated?
Maybe x11docker fails to stop the container, and docker tries to keep some shared files.
Are there other files left than store.info in the cache?
Could you run ls -l in cache and show me the output?
Unfortunately I cannot run docker in Windows on my laptop, so it is a bit hard to debug.

That's the output after running x11docker --desktop -- x11docker/xfce

As i can see the last debug lines tries to remove the store.info file.
After that if I run docker ps, no containers appears to be running. The files in my .cache folder after the first attempt are these:
$ ls -ld $(find .)

Another interesting thing is that the unique file i cannot delete is specifically the store,info file.

I#ve fixed one issue i see in the output of DEBUGNOTE[15:28:05,256]: finish(): Checking pid CONTAINER1467f .... The container id should not be handled as a pid.
However, that still does not explain the store.info issue and is probably unrelated.

Another interesting thing is that the unique file i cannot delete is specifically the store,info file.

store.info is accessed within the container at a very late point to store the exit code of the final container command. Maybe store.info is deleted already at this point of time and causes trouble.
Maybe x11docker should wait a bit for this possible entry (cmdexitcode) before terminating.

Maybe x11docker should wait a bit for this possible entry (cmdexitcode) before terminating.

I've included a non-elegant hotfix to wait for the container exit code before deleting the cache. Maybe that helps. If yes, I'll think about a more proper solution.

I'm not at home right now, but i'll check it today or tomorrow.

Still not working, but at least the folder of each container created is removed inside .cache folder. Maybe the problem is related with the .cache folder that is somehow retained by docker somehow.

First try:

Maybe a solution could be create a .cache- folder each time x11docker run and remove it on SIGINT. I don't know what could be :(

Still not working, but at least the folder of each container created is removed inside .cache folder.

~/.cache/x11docker has no cache subfolders afterwards? That are good news.
However, it is odd that the issue persists.
It is also odd why only store.info is affected. Other files are accessed from container, too, especially share/stdout and share/stderr.

Maybe a solution could be create a .cache-containerid folder each time x11docker run and remove it on SIGINT. I don't know what could be :(

Currently x11docker creates a cache subfolder for each container in ~/.cache/x11docker and removes it afterwards. You assume that docker somehow retains ~/.cache/x11docker itself?

It would be possible to create a ~/.cache/x11docker-NNN for each container. But that would be an ugly workaround, not a real solution. I hope we'll find and fix the underlying issue.

I've tried to run with --debug option but it does not work
/usr/bin/x11docker: line 977: Drive: unbound variable

I've fixed this issue, --debug should continue now. It stops x11docker on each minor error.
Please try again with --debug.

I think that because it is possible to delete the folder when docker is stopped, but I am not 100% sure.

Yes, that would pollute the home folder of the user.

Please try again with --debug.

Ok, i have tried with --debug option. I've removed .cached folder and the output is that:

Thank you for your patience with the tests.
I've fixed the visible new --debug errors. It would be nice if you try and report as often with --debug until all issues it shows are fixed.
Your cache check with ls -ld $(find .) looks pretty well, no disturbing file permissions are visible. So I doubt creating another cache folder structure would help.
I've added two additional note outputs showing ls -ld $(find .) at start and at stop of x11docker. Maybe that gives a hint.
I've also disabled the late storage of the container exit code in store.info, maybe that makes a difference.
Could you please try again, with and without --debug?

Thank you for your patience with the tests.

No problem. I really like this project and I see good potential use cases for this.  If I have time I would like to contribute a little bit in the future and check different environments :).
I see a little typo error in lines in lines 509 and 6929. I substituted this lines with:
$(ls -ld $(find $Cachefolder))". I just removed the \ of \$.
After install it the output of the first try is this. As usual it works:

DEBUGNOTE[20:18:14,190]: time to say goodbye (traperror)

Maybe it's important to say that my cygwin folder is located in C:\cygwin64

Good to see that --debug now runs overall. I've fixed some unrelated issues seen in the output.
The second log shows wrong file ownership of store.info:

-rw-r-----  1 Unknown+User Unknown+Group    736 Sep 22 20:17 /home/Darwin/.cache/x11docker/x11docker-xfce-76162803841/share/store.info

In the first log it is ok. I have no idea why the first startup works fine, but the second one does not. There should be no relation at all between the two starts.
The cache folder names are different as intended, x11docker-xfce-75941500095 versus x11docker-xfce-76162803841.
I suspect one line in storeinfo() that might cause trouble: https://github.com/mviereck/x11docker/blob/master/x11docker#L882
sed -i "/^$(echo "${1:-}" | cut -d= -f1)=/d" should drop old entries. It fails expectedly in one case in the container due to file access issues, but that should cause no harm. It should just fail without doing anything. But maybe it confuses docker-for-win or Cygwin.
x11docker does not need this sed line, it is only included for general purposes. I have disabled it now. Maybe that makes a difference.

Ok, now it's working perfectly :). Here is the log if it is necessary.
$ x11docker --desktop --gpu --init=systemd -- x11docker/xfce
grep: /etc/os-release: No such file or directory
grep: /etc/os-release: No such file or directory
x11docker note: Using X server option --xwin

x11docker WARNING: Option --gpu degrades container isolation.
  Container gains access to GPU hardware.
  This allows reading host window content (palinopsia leak)
  and GPU rootkits (compare proof of concept: jellyfish).

x11docker note: Option --init=systemd is not possible on MSYS2/Cygwin/WSL.
  systemd needs a running linux kernel with cgroup support.
  You can try another init option instead, e.g. --init=openrc.
  Fallback: Disabling option --init=systemd

x11docker note: Windows firewall settings can forbid application access
  to the X server. If no application window appears, but no obvious error
  is shown, please check your firewall settings. Compare issue #108 on github.

x11docker note: Failed to add container user to group render.

Thank you very much for your time. I'll notice if I see other issues :)

Great! :-)
Could you please run once more with --debug? I want to see if there are some minor issues left.
In your prvious log I see two issues:

grep: /etc/os-release: No such file or directory

Should be fixed now, the error should not be shown anymore,

(xfwm4:169): xfwm4-WARNING **: 01:27:38.321: The display does not support the XComposite extension.
(xfwm4:169): xfwm4-WARNING **: 01:27:38.326: Compositing manager disabled.

x11docker disables the composite extension for XWin. You can enable it with inoffical/experimental option --xcomposite. Could you run a test if if works? Probably I had a reason to disable it for XWin, but I don't remember.

Of course. That's the log running with --debug and --xcomposite
$ x11docker --desktop --xcomposite --debug -- x11docker/xfce^C

Darwin@DESKTOP-EPQAUIL ~/x11docker
$ x11docker --xcomposite --desktop --debug -- x11docker/xfce
x11docker note: Option --xcomposite: experimental only.

Thanks!
Good, the --debug output does not show any issues anymore.
Overall the startup seems to be quite slow, it takes more than half a minute.
I am not sure if I can do anything about that. x11docker does a lot of file accesses, and Windows it not really designed for this. I assume that the startup would be faster in WSL, but I am not sure.
