Some comments here from a very cursory pass over this.

Is the documentation for this intended to be part of a separate PR? Either way, feel free to ping me for a review when it's available.

About changes of the inspect module and backward-compatibility, let me have a look.

  • getargs() and getargspec() API is unchanged
  • getfullargspec() gets a new posonlyargs field in its FullArgSpec type: getfullargspec()[5] now returns posonlyargs rather than kwonlyargs
  • formatargspec() gets a new 'posonlyargs' positional-or-keyword argument between "defaults" and "kwonlyargs": this change looks backward incompatible.

Maybe something should be done for getfullargspec() and formatargspec().

getfullargspec() was deprecated but then became undeprecated again... https://bugs.python.org/issue20438

My advice is to merge this PR as it is. Maybe it's not perfect: that's ok. The important part is to get the new syntax as soon as possible, to get enough time to play with it before Python 3.8.0 final. I expect that subtle issue will be found, and I prefer to find them before the final rather than after.

I suggest to leave inspect unchanged but open a new issue on bugs.python.org or open a thread on python-dev to decide how to handle the backward-compatibility. IMHO there is no good solution, only compromises. You cannot add support for positional-only arguments and leave the API unchanged. I'm talking about getargs(), getargspec(), getfullargspec() and formatargspec() functions. signature() is fine if I understood correctly.

I have removed the changes in inspect.py that affect deprecated functions (getargspec...) and we raise if the user passes something that has positional only arguments.

We already raise if you pass keyword only or an annotation for that API:

That was my proposal. IMHO it's the safest option for "legacy" functions of the inspect module, to ensure that we don't introduce any subtle backward-incompatible change.

I modified the warnings module to add a new "source" parameter at the end. It took me 3 years to fix regressions on corner cases... The latest one was be7c460 See https://bugs.python.org/issue26568 and https://bugs.python.org/issue35178

I tried to have the backward-compatibility in mind when I modified the warnings module, but there are always subtle issues...

IMHO getargs(), getargspec(), getfullargspec() should be deprecated in favor of signature() which is future-proof. But Nick Coghlan undeprecated these functions in 2017 https://bugs.python.org/issue20438 whereas these were deprecated since 2015. I didn't understand the subtle issues.

Again, that's why I suggest to open an issue afterwards to discuss the subtle inspect API :-)

@pablogsal: Please merge your PR.

Serhiy Storchaka complained about backward incompatible changes on the inspect module:
https://bugs.python.org/issue36540#msg340246

But I made the same complain and you fixed it. IHMO the change is now good enough to be merged.

Serhiy said nothing for 2 weeks. alpha4 release is today. I would prefer to get this implementation merged as soon as possible: as Lukasz if I understand correctly.

This is breaking change. getfullargspec() was added to avoid breaking old getargspec(). You need to add a new function (getfullerargspec()?) and deprecate getfullargspec().

Since all these parameters are positional-or-keyword, inserting a new parameter in the middle is breaking change. You can add it only to the end. Or add a new function.

Did you see that the PR has been modified to no longer touch the existing API, except of signature(), but raise an exception of the "legacy functions" are called on a function which has positional-only arguments? #12701 (comment)

Hi! The buildbot x86 Windows7 3.x has failed when building commit 8c77b8c.

False positive. It is some problem in the multiprocessing module.
