When this commit was applied commit 9894dc0cdcc397ee5b26370bc53da6d360a363c2 Author: Daniel P. Berrange <berra...@redhat.com> Date: Tue Jan 19 11:14:29 2016 +0000
char: convert from GIOChannel to QIOChannel The tcp_chr_recv() function was changed to return QIO_CHANNEL_ERR_BLOCK which corresonds to -2. As such the handling for EAGAIN was able to be removed from tcp_chr_read(). Unfortunately in a later commit: commit b6572b4f97a7b126c7b24e165893ed9fe3d72e1f Author: Marc-André Lureau <marcandre.lur...@redhat.com> Date: Fri Mar 11 18:55:24 2016 +0100 char: translate from QIOChannel error to errno The tcp_chr_recv() function was changed back to return -1, with errno set to EAGAIN, without also re-addding support for this to tcp_chr_read() Reported-by: Aleksey Kuleshov <rnd...@yandex.ru> Signed-off-by: Daniel P.
