Robert Lazarski resolved AXIS2C-1605.
-------------------------------------
Fix Version/s: 2.0.0
(was: 1.7.0)
Resolution: Fixed
Before
SSL_shutdown(ssl); /* Only sends close_notify */
SSL_free(ssl);
After
shutdown_ret = SSL_shutdown(ssl);
if (shutdown_ret == 0)
{
/* Shutdown not yet complete - call again for peer's close_notify */
SSL_shutdown(ssl);
}
SSL_free(ssl);
How This Fixes CLOSE_WAIT
┌──────┬────────────────────────────┬──────────────────────────────┐
│ Step │ Before (Broken) │ After (Fixed) │
├──────┼────────────────────────────┼──────────────────────────────┤
│ 1 │ Send close_notify │ Send close_notify │
├──────┼────────────────────────────┼──────────────────────────────┤
│ 2 │ Free SSL immediately │ Wait for peer's close_notify │
├──────┼────────────────────────────┼──────────────────────────────┤
│ 3 │ Socket stuck in CLOSE_WAIT │ Clean connection close │
├──────┼────────────────────────────┼──────────────────────────────┤
│ 4 │ - │ Free SSL │

> When using Axis2/C client with internal http transport via SSL and HTTP/1.0

> failure to invoke web service anymore.
