Add support for cpr 1.6.2 #5353

ollien · 2021-04-28T01:24:55Z

Specify library name and version: cpr/1.6.2

I had just worked on cpr/1.6.0, and now that cpr/1.6.2 is released, I figured I'd give it an update :) Flags are added for darwinssl, and for disabling ssl entirely (we previously disabled SSL if none was selected, but doing so precludes CPR from attempting to auto-detect).

I've read the guidelines for contributing.
I've followed the PEP8 style guides for Python code in the recipes.
I've used the latest Conan client version.
I've tried at least one configuration locally with the
conan-center hook activated.

Suggested change

return tools.Version(self.version) >= "1.6.1"

return tools.Version(self.version) >= "1.6.1" and tools.is_apple_os(self.settings.os)

I read this change and I could have SWORN I already did it. Guess not, lol. On it.

I was afraid of this...

Can we copy the curl recipe and use an with_ssl and provide string options? and deprecate the older two?

You know, that makes total sense, and frankly I don't know why I didn't think about it. Will do.

Is there a proper way to deprecate options, by the way? I took a quick peek at the docs and didn't see it

#5020 We just wrote it recently 🎉

Oh awesome! Will flip to using that way

ollien · 2021-04-28T02:42:25Z

I know why CI is failing, small error on my part with one of the old SSL options. Will be fixed along with everything else...

Would it be easier if we used the name value?

Sorry, not sure what you're referring to here. Could you clarify?

There's a bit of complexity from the CPR values being different from the curl recipe...

But looking at it again, it's just combinatorics hell, since the options and support have changed a lot it's very complicated

Perhaps this should be moved to config_options

such that the default is sensibly configured. We also try to no shock the user by override their explicit input and a minimum this should be a raise ConanInvalidConfiguration

Makes total sense. Will fix this up later today.

We are trying typing to maintain support for older python versions, could you please use "".format() instead please?

Ah shoot - wasn't thinking about that. I've been in the f-string mindset for too long 😅

LGTM!

right now, the selection is completely random. we'll see how is it going, and if further tuning is needed.

Because this will break python2 and there is no typing in conanfiles at all.

I would instead raise in validate, if libcurl uses different SSL implementation because overriding user's desires is not something we should do.

Okey doke. I did this primarily to mirror what was already there but I'll give this a fiddle and see how it works out.

Let's just remove, because accessing validators[library] will raise more-or-less the same error and as you noted it's not gonna happen at all.
