Internal server error possibly caused by 4.23.1 update

[bviktor]

Unfortunately I'm not sure if the 4.23.1 update broke it, all I know is it used to work before (on 4.23), but now if I go to snippets (either top menu, or under a user/group), I get this error:

Gist plugin is at 4.13.0. Can anyone repro?

[takezoe]

I tested and it worked fine in my local environment. Try to once uninstall the plugin and re-install.

[bviktor]

Oh, that might be a problem. What's the recommended way to upgrade when you have plugins installed? Is there docs for that?

[bviktor]

Yup, a simple uninstall & install solved this :) Do I have to do this after each GitBucket upgrade?

[bviktor]

... for all non-default plugins?

[takezoe]

When you upgraded GitBucket, all bundled plugins should be upgraded automatically.
If it doesn't happen, it's a bug in GitBucket.

[bviktor]

Okay, but snippets (gist) is not a bundled plugin, it was installed manually. Do I have to reinstall all of these after GitBucket upgrades?

[takezoe]

Bascally, you don't need it.

But sometimes GitBucket updates contain binary imcompatibility. You have to update some plugins in such case. In addition, Gist plugin is now bundled with GitBucket. So you don't need to install it manually any longer. 😉

[bviktor]

Ah, I missed that. Which release added it?

[takezoe]

They were added in GitBucket 4.15.0:

[bviktor]

That's a pretty big oversight on my part, thanks a lot for all the help Takezoe, much appreciated!
