Daniel P. Berrange	e886237af5	Enhance the streams helper to support plain file I/O ... The O_NONBLOCK flag doesn't work as desired on plain files or block devices. Introduce an I/O helper program that does the blocking I/O operations, communicating over a pipe that can support O_NONBLOCK * src/fdstream.c, src/fdstream.h: Add non-blocking I/O on plain files/block devices * src/Makefile.am, src/util/iohelper.c: I/O helper program * src/qemu/qemu_driver.c, src/lxc/lxc_driver.c, src/uml/uml_driver.c, src/xen/xen_driver.c: Update for streams API change	2011-03-29 12:17:28 +01:00
Daniel P. Berrange	35416720c2	Put <stdbool.h> into internal.h so it is available everywhere ... Remove the <stdbool.h> header from all source files / headers and just put it into internal.h * src/internal.h: Add <stdbool.h>	2011-02-24 12:04:06 +00:00
Daniel P. Berrange	7c08fcc439	Add a generic internal API for handling any FD based stream ... To avoid the need for duplicating implementations of virStream drivers, provide a generic implementation that can handle any FD based stream. This code is copied from the existing impl in the QEMU driver, with the locking moved into the stream impl, and addition of a read callback The FD stream code will refuse to operate on regular files or block devices, since those can't report EAGAIN properly when they would block on I/O * include/libvirt/virterror.h, include/libvirt/virterror.h: Add VIR_FROM_STREAM error domain * src/qemu/qemu_driver.c: Remove code obsoleted by the new generic streams driver. * src/fdstream.h, src/fdstream.c, src/fdstream.c, src/libvirt_private.syms: Generic reusable FD based streams	2010-11-11 16:02:57 +00:00
