Jerboa crashes when post contains an invalid date format (double Z at the end)

[frebib]

Edit: Crash logs further down: https://github.com/dessalines/jerboa/issues/1230#issuecomment-1715536070

I'll start by saying that I'm sorry this report is a bit sparse.. I don't know how to collect crash logs, especially seeing as the app stays running for maybe 200ms before crashing. Happy to provide some if someone points me at instructions.

So this started maybe a week ago? It only happens if I'm logged into my personal Lemmy instance. If I clear app data, it works fine until I again log in. I'm running the latest version (0.46-alpha from GitHub) and whatever the latest Lemmy container version is at the time of writing. I'm not sure what else to try

[MV-GH]

If it doesn't always crash, go to settings > about > crash logs

But those will be gone if u deleted appdata

In the issue bug creation menu at the bottom there is entire guide to get the logs. Which would really need to understand the cause.

[MV-GH]

Btw another thing, when it crashes on startup can you turn off internet. And see if it still crashes if not. Definitely get crash logs from the crashlogs section in About.

I submitted this report on mobile so didn't see the helpful text there :( Thanks GitHub. Unfortunately it always crashes

I'll give adb a go later. Thanks :)

[frebib]

Oh that's much easier. ...lol

Looks like a double zulu on the date

Your custom instance what version is it running? is it running the latest main? Or just 0.18.4? The latest main already contains breaking changes for 0.19 which Jerboa does not support yet.

[MV-GH]

Jerboa should definitely handle datetime parse failures better. But this is also backend issue, Lemmy should not be creating bad timezones.

[frebib]

According to the UI

UI: 0.18.4 BE: 0.18.4-beta.8

I'm not doing anything custom per-se

I'm using the dessalines/lemmy and dessalines/lemmy-ui Docker images (:latest tag... maybe I should pin or find a "stable" tag or something)

Either way, seems like a server-side issue

[MV-GH]

If your are using the latest changes your are using the main with 0.19 changes. Could you report this at Lemmy that the main is creating badbly formatted datetimes

[guillaume-uH57J9]

Hi !

I just experienced a startup crash of Jerboa with the same exception (ie java.time.format.DateTimeParseException) and same callstack as mentioned in an earlier comment.

What can I do as a user? @frebib mentioned "server-side issue" but I'm not a server admin. Should I recommend the server admin apply a fix or update to a specific version?

Client: Jerboa 0.0.45 Server: BE 0.18.4

[guillaume-uH57J9]

Just updated to Jerboa 0.0.46 via F-Droid. The startup crash persist. Jerboa's UI suddenly disappear while loading posts/homepage. Scoop collects a similar error log that includes a double Z in the date.

Which instance and what BE version does it say? This is very strange that it happens to a 0.18.4 version. In 0.19 that will come they made changes to the datetime which probably introduced the problem. I wasn't aware of this happening earlier.

Right now as a user the only thing you can do delete appdata and do not login with that instance as it has problems. Make your admin aware of the potential problems.

I will definitely look into making sure this won't crash Jerboa in the future but this won't be for a while.

[guillaume-uH57J9]

@MV-GH The instance is beehaw.org, and BE version is 0.18.4 at the time of testing (cf previous comments).

I'll share this issue's link with admins.

[MV-GH]

Thanks, I do have some questions for those admins. Are they running a custom version of lemmy 0.18.4? Have they cherrypicked any 0.19 changes into their BE? especially regarding time. Or maybe it's a existing issue that only recently started happening due to locale/ time changes

[MV-GH]

Nvm this was entirely caused clientsided (By jerboa), Due to changes in timezone handling in 0.19. Which Jerboa did not support yet.

Still strange that Beehaw was encountering these issues though.
