test: fix racey-ness in tls-inception #1040
Conversation
Fix test failure on FreeBSD and SmartOS, which happens due to a bad timing: events.js:141 throw er; // Unhandled 'error' event ^ Error: read ECONNRESET at exports._errnoException (util.js:734:11) at TLSWrap.onread (net.js:538:26) The outer `net.conncet()` socket stays alive after the inner socket is gone. This happens because `.pipe()`'s implementation does not `destroy` the source side when the destination has emitted `close`. Fix: nodejs#1012

Confirmed that the patch indeed fixes the race on FreeBSD and SmartOS (solaris). Thanks, @indutny. |
Good! Please review, @iojs/crypto @iojs/collaborators |
If calling socket.destroy() explicitly on close fixes it, doesn't that suggest there's a streams bug somewhere? /cc @chrisdickinson. |
@bnoordhuis it might be that the socket was closed without sending the shutdown on it. At least it doesn't get EOF event, so here we have ECONNRESET. |
"close" and "destroy" are pretty underspecified per base streams. "close" will unpipe any upstream stream from the emitter. If a streams1 stream is the emitter, it will attempt to call |

dest.on('close', function() { | ||
socket.destroy(); | ||
}); |

Ah! that's the problem. dest
is a streams3 stream, which does not call destroy
on downstream streams on close
. streams1 streams would call destroy on downstream streams.
I guess my only remaining question is: should we set up |
@chrisdickinson it should not happen under test conditions. |
LGTM, then. |
@bnoordhuis LGTY too? |
Um, I suppose so. @chrisdickinson's explanation about streams1 vs. streams3 objects makes it sound like there is a loaded gun waiting to blow off the feet of anyone mixing them in an application. I find it slightly worrying. |
