<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So, I always get nervous every time I see a 'sanity' check polling loop :-)
I know Thava took a similar approach on the patch on ASTERISK-23099 without the sanity check:
+ if (ast_wait_for_input(session->fd, 100) > 0) {
+ while ((readlen = fread(&(buf[readnow]), 1, MAXIMUM_FRAME_SIZE, session->f)) < 1) {
+ int ferr = ferror(session->f);
+ int feoffile = feof(session->f);
+ ast_debug(3,"ast_websocket_read() fread error ferr=%d, feoffile=%d, returnval=%"PRIu32"\n", ferr,feoffile,readlen);
+ }
+ }
I think your approach of checking for EAGAIN is better - was that to work through the case that you mention in the comments, where the fd says it is ready to be read, but in reality no data is available?</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Yes the EAGAIN check is exactly because of that AFAIR</pre>

* Flush the websocket session FILE* as fwrite() may not actually guarantee sending
the data to the network. If we do not flush, it seems that buffering on the SSL
socket for outbound messages causes issues
* Refactored ast_websocket_read to take into account that SSL file descriptors
may be ready to read via fread() but poll() will not actually say so because
the data was already read from the network buffers and is now in the libc buffers
This should fix an issue that I have experienced and other users may have reported [1][2][3], where
secure websockets wouldn't work, messages seem to not make it into Asterisk

I did both WS and WSS calls, confirmed audio works with chrome. This patch is for Asterisk 11 as the issue is reported on Asterisk 11, but I tested a few months ago and same issue existed on 12 and trunk. I created my own team branches for those too (/team/moy/webrtc-11, /team/moy/webrtc-12, /team/moy/webrtc-trunk)
Confirmed working by Sean Bright on Jan 20, 2014 on Asterisk 11 (see ASTERISK-21930 comment)</pre>
