Incompatibility with vue 2.7

[mdcarreira]

After upgrading to vue:2.7, which has composition-api built in, I started getting this compilation error when running my app:

 ERROR  Failed to compile with 1 error                                                                                                                                 12:19:59 PM

Is there anything I'm missing to make this work? Or is vue-concurrency incompatible with vue:2.7?

Hello @mdcarreira it's quite possible the library is incompatible with vue 2.7. For a long time the situation was that in case of Vue 2 I had to require the @vue/composition-api module.

I had a lot of issues making the lib compatible with both Vue 3 and Vue 2. This actually makes it easier.

I think I'll support only Vue 2.7 in new version of vue-concurrency. But I'm swarmed with work, not sure if I can manage to do it in this or next week.

Hey @MartinMalinda, thanks for the fast reply!

Yeah, I understand. If I knew more about vue, I might try to give you a helping hand and make a PR. But unfortunately I'm a vue noob...

I'll keep watching your repo and crossing my fingers that you will find the time to look into it :)

[mdcarreira]

@MartinMalinda, by any chance have you managed to look into this or plan to look into it soon?

Sorry for being insistent, but we've come into a point where we cannot upgrade to vue 3, neither want to downgrade back to vue < 2.7... So if you are not planning to update vue-concurrency to support vue 2.7, we will need to find an alternative solution :(

[MartinMalinda]

hi @mdcarreira, yes I gave it a try and unfortunately vue-concurrency does not run well in 2.7. Seems like the reactivity implementation there is different from the previous @vue/composition-api module because I'm seeing errors I haven't seen before with Vue 2.

I suspect this has something to do with its reactive implementation and maybe the errors point out some problems within my code, but I don't have time in the nearby future to refactor the lib:(

[MartinMalinda]

To be more precise, using a task leads to RangeError: Maximum call stack size exceeded. Seems like I'm not alone:
vuejs/vue#12750

[mdcarreira]

Argh, that's a shame... Thanks for letting me know the current state of things!

Is this fixed in the latest 2.7 release? I noticed there is handful of reactivity changes.

[MartinMalinda]

@Hawxy I just tried and yes, unfortunately

[dschmidt]

yes, unfortunately it's fixed? Why is that unfortunate?

[MartinMalinda]

A too quick answer from me, sorry. I mean the error is unfortunately still present. It's still going in infinite loop.
