Closes issue #1096. ........ r58097 | bill.janssen | 2007-09-10 23:51:02 +0200 (Mon, 10 Sep 2007) | 33 lines More work on SSL support. * Much expanded test suite: All protocols tested against all other protocols. All protocols tested with all certificate options. Tests for bad key and bad cert. Test of STARTTLS functionality. Test of RAND_* functions. * Fixes for threading/malloc bug. * Issue 1065 fixed: sslsocket class renamed to SSLSocket. sslerror class renamed to SSLError. Function "wrap_socket" now used to wrap an existing socket. * Issue 1583946 finally fixed: Support for subjectAltName added. Subject name now returned as proper DN list of RDNs. * SSLError exported from socket as "sslerror". * RAND_* functions properly exported from ssl.py. * Documentation improved: Example of how to create a self-signed certificate. Better indexing. ........ r58098 | guido.van.rossum | 2007-09-11 00:02:25 +0200 (Tue, 11 Sep 2007) | 9 lines Patch # 1140 (my code, approved by Effbot). Make sure the type of the return value of re.sub(x, y, z) is the type of y+x (i.e. unicode if either is unicode, str if they are both str) even if there are no substitutions or if x==z (which triggered various special cases in join_list()). Could be backported to 2.5; no need to port to 3.0. ........ r58099 | guido.van.rossum | 2007-09-11 00:36:02 +0200 (Tue, 11 Sep 2007) | 8 lines Patch # 1026 by Benjamin Aranguren (with Alex Martelli): Backport abc.py and isinstance/issubclass overloading to 2.6. I had to backport test_typechecks.py myself, and make one small change to abc.py to avoid duplicate work when x.__class__ and type(x) are the same. ........ r58100 | bill.janssen | 2007-09-11 01:41:24 +0200 (Tue, 11 Sep 2007) | 3 lines A better way of finding an open port to test with. ........ r58101 | bill.janssen | 2007-09-11 03:09:19 +0200 (Tue, 11 Sep 2007) | 4 lines Make sure test_ssl doesn't reference the ssl module in a context where it can't be imported. ........ r58102 | bill.janssen | 2007-09-11 04:42:07 +0200 (Tue, 11 Sep 2007) | 3 lines Fix some documentation bugs. ........ r58103 | nick.coghlan | 2007-09-11 16:01:18 +0200 (Tue, 11 Sep 2007) | 1 line Always use the -E flag when spawning subprocesses in test_cmd_line (Issue 1056) ........ r58106 | thomas.heller | 2007-09-11 21:17:48 +0200 (Tue, 11 Sep 2007) | 3 lines Disable some tests that fail on the 'ppc Debian unstable' buildbot to find out if they cause the segfault on the 'alpha Debian' machine. ........ r58108 | brett.cannon | 2007-09-11 23:02:28 +0200 (Tue, 11 Sep 2007) | 6 lines Generators had their throw() method allowing string exceptions.

This requires adding the 'makefile' method to ssl.SSLSocket, and importing the requisite fakefile class from socket.py, and making the appropriate changes to it to make it use the SSL connection. Added sample HTTPS server to test_ssl.py, and test that uses it. Change SSL tests to use https://svn.python.org/, instead of www.sf.net and pop.gmail.com. Added utility function to ssl module, get_server_certificate, to wrap up the several things to be done to pull a certificate from a remote server. ........ r58173 | bill.janssen | 2007-09-17 01:16:46 +0200 (Mon, 17 Sep 2007) | 1 line use binary mode when reading files for testAsyncore to make Windows happy ........ r58175 | raymond.hettinger | 2007-09-17 02:55:00 +0200 (Mon, 17 Sep 2007) | 7 lines Sync-up named tuples with the latest version of the ASPN recipe.

All protocols tested with all certificate options. Tests for bad key and bad cert. Test of STARTTLS functionality. Test of RAND_* functions. * Fixes for threading/malloc bug. * Issue 1065 fixed: sslsocket class renamed to SSLSocket. sslerror class renamed to SSLError. Function "wrap_socket" now used to wrap an existing socket. * Issue 1583946 finally fixed: Support for subjectAltName added. Subject name now returned as proper DN list of RDNs. * SSLError exported from socket as "sslerror". * RAND_* functions properly exported from ssl.py. * Documentation improved: Example of how to create a self-signed certificate.
