There was change in libssh2_channel_read_ex, in the check of rc < 0
if (channel->read_block) {
/* in the second lap and onwards, do this */
rc = libssh2_packet_read(session);
channel->read_packet = session->packets.head;
}
/* We didn't read any data from the socket and
* no packets are waiting to be read */
if ((rc < 0) && (! channel->read_packet)) {
if (rc != PACKET_EAGAIN) {
channel->read_state = libssh2_NB_state_idle;
}
/* no packets available */
return rc;
}
This is causing problems for me, the code appears to spin in some busy
wait loop.
This issue is that rc == LIBSSH2_ERROR_EAGAIN and
session->packets.head is not NULL, so the error checking code is not
entered. Reverting that line by removing the "&& (!
channel->read_packet)", make the code work again.
Code is from libssh2-0.19.0-20081020, compiled with mingw on win XP,
and used in libcurl.
