jruby-openssl: SSLSocket.syswrite error for big (>16k) data
-----------------------------------------------------------
Key: JRUBY-3288
URL: http://jira.codehaus.org/browse/JRUBY-3288
Project: JRuby
Issue Type: Bug
Components: JRuby-extras, OpenSSL
Affects Versions: JRuby-OpenSSL 0.3
Environment: Linux mort-note 2.6.27-11-generic #1 SMP Fri Dec 19
16:29:52 UTC 2008 i686 GNU/Linux
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Client VM (build 11.0-b15, mixed mode, sharing)
jruby 1.1.5, jruby 1.1.6
Reporter: Miklos Bali
Using jruby-openssl if I try to write large chunks of data on a secure socket,
the write seems to be OK, but it looks like the other size doesn't receive all
of it. Experimenting with {{OpenSSL::TestSSL}} testcase's
{{test_read_and_write}} test, I could reproduce this behavior, and it looks
like the upper limit of bytes for which the test succeeds is 16384.
If I change
{{str = "x" * 100 + "\n"}}
to
{{str = "x" * 16 * 1024 + "\n"}}
, syswrite returns 16385 as expected, but the sysread after that hangs, and
nothing is coming back from the server (According to Wireshark).
I've found no other workaround yet, than to "manually" chop up the data I send.
