John Levon added the comment:
I checked, and the supposition this is due to lack of closefrom() doesn't seem
to be correct. Running the test case and looking at 'truss' output, there is no
large number of close() that one would expect if this was the issue.
I don't se
John Levon added the comment:
closefrom() is on both Solaris and illumos too - and might even have originated
there as an API - so if that's the issue, it should be trivially fixable

Jesus, yes, it's totally possible that POSIX might define:

to mean something other than S_IDOOR. However, the POSIX committee

AC_MSG_RESULT($with_dtrace)
Why twice? It looks confusing.

The posted patch: better if the PACKET_* tests were just at the two missing

John Levon added the comment:
This is not a bug in Solaris - the interfaces Python is trying to use are not
standardized.
(It's a reasonable RFE for Solaris to fully support these, though - I'll follow
up on that.)
WRT the patch, at least the PACKET_* defined would be better
John Levon added the comment:
Anatoly, see above. We have done exactly that. (Honestly, when I first wrote
the changes, I saw them as too hacky to ever be accepted upstream).
This name change seems frivolous and will indeed break existing scripts

That's a little abrupt. Whilst it would be nice if the compiler had a correct
return value, it occurs with multiple compilers, and I pointed
you to a suitable workaround Python could employ. Even if Studio gets fixed,
there are previous releases out there
John Levon added the comment:
Terry, what in the above discussion leads you to believe there is no bug?
The original complaint "Python cannot be embedded in shared library due to
dependency problems with lib-dynload" is still valid.

It's not clear why you'd need configure tests, but you could easily add the
define in the body of the autoconf test AFAIK - is there a reason this is

This appears to be one of the few cases where there's incompatibilities between

Hmm. Try adding -Z to see if that helps.

Surely readline is irrelevant anyway. The Python spec guarantees

This is indeed a reasonable concern (for which the best solution is

Actually, I was saying that below that value simply won't work
John Levon added the comment:
Python should define *only* __EXTENSIONS__, not the others, as Zooko
already mentioned, for the reasons he mentioned. I'm not sure how you
got a different impression from what I or he said.
