Unreadable images aren't handled properly

[jgarte]

Hi,

I'm not sure what I should call this error but ement keeps complaining about the below.

I turned on toggle-debug-on-error and this is what I got.

WDYT

Feel free to rename this issue to something more pertinent.

Hello,

Thanks for reporting this problem.

1. What version of Emacs do you have, and where did the build come from?
2. What version of Ement do you have?
3. Does the problem happen if you run Ement in a clean Emacs config, e.g. with https://github.com/alphapapa/with-emacs.sh ?

[jgarte]

1. GNU Emacs 29.0.90 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, cairo version 1.16.0)
2. 0.8.3
3. I'll get back you on this one as I'll have to find the time to read the setup for with-emacs.sh and test it.

[alphapapa]

Thanks.

1. GNU Emacs 29.0.90 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, cairo version 1.16.0)

Do you have a version of Emacs 28 or 27 to test with? Emacs 29 is not yet released, so it would be helpful to know whether we're looking at a change in Emacs 29 or something else.

2. [ 0.8.3](https://toys.whereis.%E3%81%BF%E3%82%93%E3%81%AA/?search=emacs-ement)

Is that the same as this? https://packages.guix.gnu.org/packages/emacs-ement/

3. I'll get back you on this one as I'll have to find the time to read the setup for `with-emacs.sh` and test it.

Basically you would run it like this:

$ with-emacs.sh -i ement

Then try to connect and use the client as you normally do.

[jgarte]

Do you have a version of Emacs 28 or 27 to test with?

Yep.

Is that the same as this? https://packages.guix.gnu.org/packages/emacs-ement/

Yep.

Basically you would run it like this:

Thanks for the TLDR. Much appreciated!

Give me a few days to do more testing and I'll get back here.

[jgarte]

Then try to connect and use the client as you normally do.

By try to connect you mean to call emacsclient with some flag to connect to the frame?

[jgarte]

BTW,

This error still occurs on emacs 28

error in process sentinel: Wrong type argument: consp, nil

GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, cairo version 1.16.0)

I got the above 28.2 with Guix and ement is same version as before.

[alphapapa]

Then try to connect and use the client as you normally do.

By try to connect you mean to call emacsclient with some flag to connect to the frame?

No, I mean to use Ement ("the [Matrix] client") as you normally do. :)

Please try running this commit: c55bc0b When encountering one of the rooms whose avatar is unexpectedly nil, it should display a warning with the room struct. With that information, we should be able to dig further and find out why the image is ending up nil. Depending on the room, the struct could be a large amount of data. Likely, we'll just need to get the room ID, and then add more debugging code to show what goes wrong with that room's avatar event.

Thanks for your help.

[alphapapa]

Also, for future reference, this should have been solved in #45, but...

[jgarte]

I ran this in a terminal:

$ guix shell emacs-next emacs-ement --with-commit=emacs-ement=c55bc0b362eab1d4d2db495c1ed285ea264295a6

The above command install emacs 29 and emacs-ement from commit c55bc0b362eab1d4d2db495c1ed285ea264295a6 in a shell environment.

I then, launched Emacs and executed ement-connect and voilà, it runs smoothly.

The error completely went away and ement not runs as smooth as butter which I hadn't experienced yet :)

I do have this new warning in *Messages* but maybe ignore or we should investigate?

PNG warning: iCCP: known incorrect sRGB profile [2 times]

[jgarte]

I'll make sure to update the Guix package once this fix is in master.

[alphapapa]

Well, that commit isn't a fix, rather it adds debugging code that should allow us to locate the problem and then fix it in the right place. As you can see in the patch, it should display a warning like Ement room avatar has no image... that should have more information about the room with the problematic avatar. Do you not see a *Warnings* buffer with a message like that?

ement no[w] runs as smooth as butter which I hadn't experienced yet :)

Yes, that's because the error is ultimately signaled from the process sentinel, which Emacs handles by pausing for 2 seconds. I've recently learned that signaling errors from sentinels is bad, so a future version of plz should solve that (i.e. those errors wouldn't cause Emacs to pause). But this error relating to a corrupt room avatar still needs to be fixed in and of itself.

[jgarte]

Oh yeah, looking at the *Warnings* buffer now. It has a ton of info. Looks like some of it might be sensitive information...

Do you need any info from it?
