Exit code 92 is not handled

[akirak]

While I was using plz.el in my library, I got the following error:

plz: plz: Curl error: "Curl error", #s(plz-error nil nil "Unexpected curl process status:\"exited abnormally with code 92 \" code:92. Please report this bug to the `plz' maintainer.")

According to curl(1), the exit code is defined as follows:

92 Stream error in HTTP/2 framing layer.

The error was from API requests to https://www.google.com/transliterate. Google might have changed the API, and now curl returns the error related to HTTP/2.

The versions are as follows:

plz.el 0.9.1 from Git curl 8.9.1 GNU Emacs 31.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.43, cairo version 1.18.0)

Hi Akira,

Well, I don't know what kind of special handling we should do for that error. I guess we could prevent that code from causing it to ask that the error be reported to me, but other than that, I think there's nothing else to be done.

BTW, I guess you could try using the --http1.1 argument to Curl, to prevent it from using HTTP/2, but I don't know if that would help.

Indeed, this has resolved the error. I will add this option to plz-curl-default-args custom variable in my config. For most Emacs applications, HTTP/2 features wouldn't be necessary.

It might be helpful if plz displayed error messages from curl. Aside from that, I agree that there is nothing plz can do to prevent this kind of error.

Given the uncertainty here, I think I'll not make any changes to the code about this. But if we get more information about this error code, maybe it would be worthwhile. Thanks.

I think that's fine. Thank you.
