gh-126742: allow to use non-UTF8 exception messages by picnixz · Pull Request #126746 · python/cpython

Issue: Allow to set non-UTF8 exception messages #126742

ZeroIntensity · 2024-11-12T14:31:16Z

Technically, since this is a bugfix, let's wait until #126555 has landed before we merge this, and then address all the uses of dlerror() in this PR.

picnixz · 2024-11-12T14:34:13Z

then address all the uses of dlerror() in this PR.

I actually thought of doing it two PRs. Technically, this specific PR can be merged without waiting for the other and then you can use this interface in the other (rather the other way around).

ZeroIntensity · 2024-11-12T14:52:20Z

Eh, I would rather not. Let's not overwhelm someone with thread states and the private API on their first PR :)

ZeroIntensity · 2024-11-13T11:53:04Z

I've removed backport labels, per what Petr said in the issue. I think he's right--let's just focus on main with this.

encukou · 2024-11-15T13:17:46Z

Hmm, just had an idea: if we add a “char* in locale encoding” format to PyUnicode_FromFormat, it'll be possible to use it with PyErr_Format -- but also for non-error messages.

ZeroIntensity · 2024-11-15T13:28:56Z

I like that idea! But we're exposing this as a public API--how often might users need this? (I've never needed to mess with locale in any of my C API usage, but to be fair I'm typically not calling APIs that return strings.)

picnixz · 2024-11-15T13:42:16Z

Hmm, just had an idea: if we add a “char* in locale encoding” format to

I'm not very fond of adding a case to additionally check when there's not a lot of use cases (unless proven otherwise). It shouldn't affect performances much (but this needs verification) but this would complicate an already complicate function I think (and people need to remember this new format as well).

ZeroIntensity · 2024-11-15T13:59:32Z

No no, I don't think he meant a variation of PyUnicode_FromFormat that takes a locale, he meant a format value %whatever that automatically calls PyUnicode_DecodeLocale or something like that.

picnixz · 2024-11-15T14:03:29Z

No no, I don't think he meant a variation of PyUnicode_FromFormat that takes a locale, he meant a format value %whatever that automatically calls PyUnicode_DecodeLocale or something like that.

And I understood. I don't think a new code should be added unless there is a real need.

ZeroIntensity · 2024-11-15T14:13:48Z

And I understood.

Ah! I couldn't tell, sorry.

A code search for PyUnicode_DecodeLocale is showing not too much real world usage--maybe that's a bad thing? Depending on how common it is for a non-UTF8 locale to break things, maybe it would be a good idea to add a format character just so people start handling it.

encukou · 2024-11-19T12:09:21Z

It could also show that we're mainly handling errors from the OS at one point -- the OSError constructor. That would be a good thing :)

Anyway, for this PR: @picnixz, do you want to add calls to the new helper(s)?

ZeroIntensity · 2024-11-19T12:29:06Z

FWIW, Bénédikt is on vacation right now. I don't think he'll be able to implement anything until next week.

I don't see the purpose of these internal functions since they are now used. This PR only adds dead code. I would prefer to see how these functions are used.

If only dlerror() uses it, why not using code using dlerror()?
