FWIW this test still passes for IO-Socket-SSL versions 1.39 and 1.40 under the exact same environment (OpenSSL 0.9.8r 8 Feb 2011) 1.41 and 1.42 fail with # SSL wants a read first ok # [server] tcp accept ok # [server] received plain text ok # [server] upgrade to_client to IO::Socket::SSL # failed to accept: SSL accept attempt failed with unknown errorerror:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number not ok # [server] ssl accept handshake done # T9 ok # [server] received client message # $!=Resource temporarily unavailable $SSL_ERROR=SSL accept attempt failed with unknown errorerror:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number and then continues to test (with more errors) 1.43 .. 1.48 fail like 1.49 perl -Iblib/{lib,arch} t/nonblock.t 1..27 ok # [server] Server Initialization ok # [client] client tcp connect ok # [client] write plain text ok # [client] upgrade client to IO::Socket::SSL # SSL wants a read first ok # [server] tcp accept ok # [server] received plain text ok # [server] upgrade to_client to IO::Socket::SSL # SSL wants a read first ok # [server] ssl accept handshake done ok # [client] connected ok # [client] nonblocking connect with 2 attempts # sndbuf=8192 ok # [server] received client message # $!=Resource temporarily unavailable $SSL_ERROR=SSL wants a write first send=2210 # wait for write # $!=Resource temporarily unavailable $SSL_ERROR=SSL wants a read first <-- hang -->

I really would like to fix these bugs on AIX, but have no access to such a system. Could anybody provide access?

I can reproduce the bug and it is releated to the setting of SO_SNDBUF, which was added to make the test more stable on MacOSX :( Looks like that setting SO_SNDBUF on AIX can make the connection really really slow, at least on localhost. I think I saw a similar problem once on older OpenBSD systems. For now it should be fixed by not setting the SO_SNDBUF on AIX. Fixed in 1.50. Thanks to Rainer Tammer for providing access to an AIX system.
