Time Out about dangerzone HOT 7 CLOSED

Probably similar to #749. I see that your OS is Windows, which means that this problem is not contained to Fedora 39 Silverblue, as we originally assumed. We need to debug further.

Out of curiosity, does this happen with every file that you try to sanitize?

from dangerzone.

Yes. You need some errorlogs?

Dang. Even with very simple ones, like this: https://github.com/freedomofpress/dangerzone/raw/main/tests/test_docs/sample-doc.doc?

You need some errorlogs?

Sure, if you can run dangerzone-cli in Windows, and copy its output, that would help. You should be able to find it under "Program files" -> "Dangerzone".

The Simple one worked:

Safe PDF(s) created successfully

Thats the output on my pdf

Failed to convert document(s)

i have had this problem, and by editing
dangerzone/isolation_provider/base.py

line 76 conversion_proc.wait(3) to '10' conversion worked.
I guess I should submit a MR to make this timeout something in settings?

@banerian Thanks a lot for this extra info. This shows that whatever is blocking the container from quitting, does not stay on indefinitely. However, the proper fix here is to find out what's the blocker in the first place. Waiting for an arbitrary number of seconds during each conversion will not cut it, I'm afraid.

I have some questions, if you have some time:

1. What is your OS and Dangerzone version?

2. Can you convert a simple document with no errors, or does that fail as well?

3. Can you give us any specifics about the documents that you are converting and you hit this error?

   • Think document type (.pdf, .doc, etc.), number of pages, if they come from a particular source, etc.
   • Even better, if you can share a ⚠️ non-sensitive ⚠️ document with us that triggers this error, that would be amazing. You can hit me up at [email protected], if you don't want to share something publicly.

4. Since you can edit the Dangerzone source, could you make the following change in the dangerzone/isolation_provider/container.py file, run dangerzone-cli, and send us its output?

   diff --git a/dangerzone/isolation_provider/container.py b/dangerzone/isolation_provider/container.py
   index cbadcc3..6553677 100644
   --- a/dangerzone/isolation_provider/container.py

(the above applies to anyone affected by this issue, thanks in advance)

Actually, I'll ping you in another issue (#749 (comment)), since this is one is a duplicate, and we can continue the discussion there.
