I propose the following changes to the libshout API to support nonblocking I/O: New functions: int shout_set_nonblocking(shout_t *self, unsigned int nonblocking): Instructs libshout to use nonblocking I/O. Must be called before shout_open (no switching back and forth midstream at the moment). unsigned int shout_get_nonblocking(shout_t *self): self-explanatory. Changed...

I don't know anything about how ssh is structured, but I think it must be a bit more complicated than that. Ssh only sets O_NONBLOCK on an fd if isatty(fd) returns false, so it's able to function with blocking input and output if the relevant

Hello, Is it safe to change lines in plugins/quota/quota-maildir.c::maildirsize_write() from ? fd = file_dotlock_open_group(.., DOTLOCK_CREATE_FLAG_NONBLOCK, ..); to ? fd = file_dotlock_open_group(.., 0, ..); ? Rationale is: exim+cpanel frequently leave stale maldirsize.lock, but when quota plugin try to dotlock maildirsize, it do this with NONBLOCK flag and just once, so first lock fails with

Attached is a patch against shout-python-0.2 which does two trivial but very useful things (1) The function "get_connected" is exported so that shout-python becomes usable in nonblocking mode. In the current version of shout-python "open" raises an exception in nonblocking mode. (2) The global interpreter lock is released in the potentially blocking functions "open", "send" and "sync". In this way a shout-python can run in blocking mode in...

Hello, I found a bug in Icecast-2.3.2. SVN trunk is affected either. The problem lies in src/net/sock.c: sock_connected() function. This function is used to check status of socket after nonblocking connect(2) and it has two implementations: select(2) and poll(2). The select branch does the right job---it gets socket status by getsockopt(2) after selecting for write. But the poll branch does not. To make things wrong, the poll implementaion takes precedense. The bug makes icecast thinking the...

If the host is slow in reading data or doesn't read data at all, blocking write calls not only blocked the program that called write() but the entire guest itself. To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how

Hi! I'm new to this mailing list, so please help out if I'm adressing the wrong forum. :) I'm working on an application accessing a mounted networkshare. Under normal circumstances there is no problem accessing reading and writing to the networkshare using POSIX open(2)/read(2)/write(2) etc. However if there is intermittent connectivity problems to the networkshare my

Hi, I got a new Cyberpower 1500AVR UPS and nut wouldn't work. It failed to detect the UPS and a strace showed that all writes to the serial port were failing with -EAGAIN. The attached patch disabled nonblocking mode on the serial port and now it works fine. Is there a reason the port was put in non-blocking mode? There's no code I could find to deal with the inevitable -EAGAIN that you'd receive on writes. Maybe the delays introduced by ser_send_pace are why it might work for some people? -jim...
