Also it's stuck on "Sending..."

If you're on Windows, you can copy-paste the debug console here. It'll say much more in this case.

[synctext]

We need a bit more info to start debugging. Can you reproduce this?

Another user reported the same issues and posted a log on the forum. He said that this only happened during the first run of 7.5.0-exp1.

No I can't seem to reproduce it (even after resorting an old backup of ~/.Tribler). Maybe it's intermittent, or related to a slow background upgrade...

This happened again. There is no option to copy-paste all key-values (Linux) debug console is not available because Tribler is closed. bug report still won't send. Screen shot attached;

[ichorid]

The actual problem is solved in #5194. The problem with not being able to send the report was already fixed in 7.5.0-exp2. @Dmole , from your report I see that you're still using 7.5.0-exp1. Please, upgrade to 7.5.0-exp2 to be able to send tracebacks.

[Dmole]

@ichorid I'll have to wait for exp3; https://github.com/Tribler/tribler/issues/5192

[ichorid]

Deployment test machine sent this for 7.5.0-exp4:

@egbertbouman , could you please look at this?

[ichorid]

Well, that's a little embarrassing to say, but the problem is still there in 7.5.0-rc1 according to Reporter...

[egbertbouman]

I can't seem to find the crash report you're referring to. Or are you referring to errno 11001/11004 (which are different exceptions)?

We've already added some code to prevent crashing on 11001 error (https://github.com/Tribler/tribler/blob/devel/src/tribler-core/tribler_core/session.py#L337), yet is still happens. That seems to be because the exception type is missing from the string that we're checking.

[ichorid]

Yep, I'm talking about 11001/11004. These two reports.

[ichorid]

socket.gaierror: [Errno -2] Name or service not known error report

[ichorid]

When I raise an Exception, its text in unhandled_errors_observer does not include the error type, thus text-based ignored-error-catchers like if 'builtins.OSError' in text and '[Errno 113]' in text: do not trigger.

The corresponding test_error_observer_ignored_error does not really test anything, because of it not using real raise calls. Instead, it checks reactions to dummy dicts.

[ichorid]

I'm handling this properly now...

[Dmole]

Good because [7.5.0-exp1] is still crashing in under 12h with

Traceback (most recent call last):
  File "/home/tribler/jenkins/workspace/Build-Tribler_release/Async-Py3-Build-Ubuntu64/tribler/src/tribler-gui/tribler_gui/event_request_manager.py", line 114, in on_read_data
RuntimeError: Task was destroyed but it is pending!

[ichorid]

@Dmole , that's a completely different error

[Dmole]

It did not show up in my search;

https://github.com/Tribler/tribler/issues?q=is%3Aissue+is%3Aopen+7.5.0-exp1+event_request_manager.py

and I assumed there may be an underlying iesue in event_request_manager.py causing one line stack traces...Looks like I typo-ed rc1 to exp1.

[ichorid]

"one-line stack traces" you're talking about are already fixed :wink:

[Dmole]

With those 2 things fixed it's a good time for rc2 IMO. (this issue is less intrusive than the others)

[ichorid]

There is a pinned issue with the RC2 todo list.

[ichorid]

Fixed in #5224
