Running rqt_bag against PyQt 5.15.6 can still crash

[clalancette]

The version of PyQt on Ubuntu 22.04 is 5.15.6, and it is a lot more picky about the types being passed into API calls. In particular, trying to pass in float values to API calls like setPointSize(self, int) result in an exception now. We've fixed some of these, but more need to be fixed. See #108 for more information.

Is there an ETA on this? This is a big problem for image based workflows

@geoeo

The runtime errors are hard to find (and time consuming), I believe the maintainers (or myself) aren't going to get around to this soon.

I think the quickest way to solve this would be to squash one error at a time as they arise. I'm going to post the stacktrace you posted in #108 below for reference. Would you be able to post any other python stack traces that arise too?

@geoeo That exact error you posted earlier should have been resolved in this rolling sync a while back. Do you have some other errors that you could post here?

[geoeo]

@ijnek Is this part of humble as well or is it planned to be?

[geoeo]

I just updated my rolling and humble via ubuntu software updater.
And now I get a different error

The error is the same in both humble and rolling

[ijnek]

@ijnek Is this part of humble as well or is it planned to be?

Yes, such bug ports are/will be backported to humble.
In regards to your last error, i have some fixes in #118. Please post more errors as you encounter them.

[geoeo]

Do you know when that pull request will be released on humble? Are they monthly/quarterly releases?

[ijnek]

Once this PR is merged, the package maintainer would have to backport the changes to the humble branch, make a new release, and then the releases will get synced to the distros when a sync happens. There is no specific schedule for the syncs, but they happen usually once every 1-2 months.

If you want to get notified about the releases, you could enable notifications for the release tag on ROS
Discourse.

In the meantime, there's nothing stopping you from building this repo from source (once the PR is merged and backported to Humble) and using it in your projects!
