PR: Pin Jedi to 0.9.0

[ccordoba12]

I ran our tests with the new 0.10.0 version and several of them are failing.

Besides, our new completions for Numpy and Matplotlib are failing with that version too.

Debian Stretch will ship with jedi v0.10.0, how should we proceed?

[ccordoba12]

We are aiming at being compatible with Jedi 0.10 in version 3.1.4, to be released in a month or so.

If the addition of Jedi 0.10 is imminent in Debian Stretch, then users will have to depend on Rope until 3.1.4 is out.

It is there already.

users will have to depend on Rope until 3.1.4 is out

Rope is Python 2 only on Debian (version 0.10.3). Upstream got reliable support for Python 3 only recently (version 0.10.4), unfortunately not in time for the freeze. How important are rope / jedi for spyder ?

How important are rope / jedi for spyder ?

They provide code completion for the Editor, so I'd say pretty important :-)

[ghisvail]

I meant spyder actually works fine without any of rope / jedi installed right? Sure, it would be a missing feature (whose importance is relative), but the rest of the editor will remain perfectly usable am I correct?

Otherwise, how far are you from having compatibility with 0.10.0? Is that something which could be cherry-picked on top of 3.1.3?

Otherwise, how far are you from having compatibility with 0.10.0?

I found some problems with 0.10.0 that we either have report upstream as errors or fix in our side. So I don't know when we'll be compatible with 0.10.0.

And there's also PR #4121.

Is that something which could be cherry-picked on top of 3.1.3?

I'd think you can cherry-pick our changes, yep.

[ghisvail]

So, the corresponding patch to PR #4121 would make spyder 3.1.3 work with jedi 0.10.0 or is there more to be done?

[ccordoba12]

is there more to be done?

Yes, there is. Our test suite is not passing with 0.10.0 even after applying #4121.
