This patch gives access to the OpenSSL version the _ssl module is linked against, through three attributes: one gives the raw integer, another the decoded 5-tuple of ints, the last one the version string as returned by OpenSSL.

(note: tested with OpenSSL 0.9.8k and 1.0.0)

Can you please add documentation as well?

I was about to open a request for this.
Thanks.

Committed, with Benjamin's permission, in r79812 (trunk) and r79813 (py3k).

>>> import ssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/ssl.py", line 62, in <module>
    from _ssl import OPENSSL_VERSION_NUMBER, OPENSSL_VERSION_INFO, OPENSSL_VERSION
ImportError: cannot import name OPENSSL_VERSION_NUMBER



Just in case it's my fault, here's what I've done before importing ssl module:

> svn up 
Updated to revision 79814.
> make distclean
...
> ./configure ; make ; make install
...

This looks rather unlikely.
Can you type "import _ssl" and then check _ssl.__file__ to see if it's
the one that's just been compiled?
Or did compilation fail?

The ./configure -> make -> make install process went fine, or at least, I think so, as it completed without reporting errors or exiting.
...But maybe I'm doing something wrong as just a little while ago I was modifying _ssl.c but wasn't able to see those changes applied.

So I'm gonna ask: when I modify *.c files, do I have to do something else other than "./configure; make; make install" in order to see the changes applied?

Anyway, here's what you asked:


root@ubuntu:/home/giampaolo/svn/python-2.7# python
Python 2.7a4+ (trunk:79814, Apr  5 2010, 23:53:01) 
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import _ssl
>>> _ssl
<module '_ssl' from '/usr/local/lib/python2.7/lib-dynload/_ssl.so'>
>>> _ssl.__file__
'/usr/local/lib/python2.7/lib-dynload/_ssl.so'
>>>

No.

If you run the Python binary from the SVN checkout directory (rather
than from an installation), _ssl should come from the build
subdirectory, not from /usr/local/lib.
Example here:

$ pwd
/home/antoine/cpython/newssl
$ ./python -c "import _ssl; print _ssl.__file__"
/home/antoine/cpython/newssl/build/lib.linux-x86_64-2.7/_ssl.so

If _ssl is coming from "/usr/local/lib/...", it means that something
modifies your sys.path so as to put that path before the path to the
just built extension modules. I can't really investigate this point for
you, but try using "python -E" instead.

Oh, sorry, I had overlooked the "make install" bit.
Well then I don't know. But you can run the interpreter without
installing :-) (just "./python")

And check the output of "make" after you have touched Modules/_ssl.c

You were right: make output had an error involving ssl I didn't notice. My bad.
