Possibility of delta updates

[srevinsaju]

Is it possible to provide the *.zsync file to ease updates? I am not familiar with pkg2appimage

It can for Travis CI but not yet for GitHub Actions.

One would have to add to appimagetool https://github.com/AppImage/AppImageKit/blob/bc5a03a0e59651bb39018f77e378c44a4cba7a5e/src/appimagetool.c#L876-L905 for GitHub Actions in addition to Travis CI.

Like I did in go-appimage here:

https://github.com/probonopd/go-appimage/blob/7fab45552eb485c0076fd310835fa7958f981de0/src/appimagetool/appimagetool.go#L547-L567

Do you want to try adding this to appimagetool?

Alternatively, one could make pkg2appimage use go-appimage's appimagetool...

[srevinsaju]

In my "workaround"-ish brain, I would have unpacked the Zoom AppImage generated using pkg2appimage and then repack it using appimagetool with --updateinformation flag to point to the continuous release. Would it be ok? If it would be, I can create a PR.

[probonopd]

appimagetool -g is supposed to do this, since manually passing --updateinformation has proven to be too error-prone for many people to get it right. (Hence, in my no go-based implementation there will be no way to specify it manually.)

[srevinsaju]

hmm. but I prefer doing everything manually. Thanks for the info about the -g flag. I will try my luck at adding Github Actions support on https://github.com/AppImage/AppImageKit/blob/bc5a03a0e59651bb39018f77e378c44a4cba7a5e/src/appimagetool.c#L876-L905

You are probably one of the few people who are willing to spend enough time to actually understand what an update information string is... ;)

[srevinsaju]

@probonopd in case you missed it, AppImage/AppImageKit#1075 aims at adding GH Actions support to the appimagetool

[probonopd]

Excellent @srevinsaju. Let's use it here once it's merged there.

[srevinsaju]

Great. Thanks :D
