I'm trying to use uclient to monitor my home network servers querying
http://ip/status . So far I was using bash + curl, but I'm trying to
learn libubox now.
So today I accidentally queried some unknown machine (random IP) and
my app crashed.
What has happened:
1) When I first called uclient_request, uclient opened socket and wrote
GET /status HTTP/1.1
Host: 192.168.0.136
Inside the ustream_fd_write, write returned -1 and errno was EAGAIN.
2) After handling control back to uloop there was another try of sending
GET /status HTTP/1.1
Host: 192.168.0.136
but this time it has failed badly during the write call. There was
SIGPIPE that wasn't handled and my app has been terminated.
Should we somehow handle SIGPIPE in uclient or disable it using SO_NOSIGPIPE?
services like procd do
- signal(SIGPIPE, SIG_IGN);
this should really be changed to work with 464e05e3 from libubox.git
unless i missed something it might be a good idea to add PIP to
uloop_setup_signals()
