Hanging when editing in cloud about polymode

[vspinu]

That's peculiar. Will check this out.

Thanks, let me know if I can provide more info. If helpful at all, it was looking for:

/a_directory_six_levels_up/DESCRIPTION

So basically,
../../../../../../DESCRIPTION

[vspinu]

Yes. Very helpful. It's probably ESS/R issue then. Thanks.

Interesting. It only happens specifically when polymode is enabled. If it's an ESS/R issue, I'd think it still has something to do with how something is interacting with polymode and jit-lock-function. Any pointers for where I could start looking into this?

The only place where DESCRIPTION is looked up is in ess-developer-mode but it should be irrelevant when the developer mode is off. So I am puzzled.

That was actually super helpful. I finally figured it out. It seems like the root cause is an ESS default setting to check whether or not a file is inside an R package when you visit it. It does this to enable developer mode if it thinks it's in a package. In this case, the initial check was causing the issue.

Setting ess-developer-activate-in-package to nil fixes it.

Thanks!

I should fix this either in polymode or on ESS side. So let's keep this open for time being. Thanks for your helpful insights.

Ah okay. Reopening. I did notice today that that same error message of not being able to find the DESCRIPTION file actually happens when opening a regular R file as well (without Polymode). It's just that normally, that hasn't had any noticeable effect so I'd never realized. With Polymode enabled though, jit-lock-function goes crazy.

I am closing this as non polymode issue. It has been fixed long time ago on ESS side and some more optimization and re-factoring is happening for the new release of eSS.
