Add public API definition for data stream handling * include/libvirt/libvirt.h.in: Public API contract for virStreamPtr object * src/libvirt_public.syms: Export data stream APIs * src/libvirt_private.syms: Export internal helper APIs * src/libvirt.c: Data stream API driver dispatch * src/datatypes.h, src/datatypes.c: Internal helpers for virStreamPtr object * src/driver.h: Define internal driver API for streams * .x-sc_avoid_write: Ignore src/libvirt.c because it trips up on comments including write() * python/Makefile.am: Add libvirt-override-virStream.py * python/generator.py: Add rules for virStreamPtr class * python/typewrappers.h, python/typewrappers.c: Wrapper for virStreamPtr * docs/libvirt-api.xml, docs/libvirt-refs.xml: Regenerate with new APIs 2009-07-10 11:18:12 +00:00			`^src/libvirt\.c$`
Add a generic internal API for handling any FD based stream To avoid the need for duplicating implementations of virStream drivers, provide a generic implementation that can handle any FD based stream. This code is copied from the existing impl in the QEMU driver, with the locking moved into the stream impl, and addition of a read callback The FD stream code will refuse to operate on regular files or block devices, since those can't report EAGAIN properly when they would block on I/O * include/libvirt/virterror.h, include/libvirt/virterror.h: Add VIR_FROM_STREAM error domain * src/qemu/qemu_driver.c: Remove code obsoleted by the new generic streams driver. * src/fdstream.h, src/fdstream.c, src/fdstream.c, src/libvirt_private.syms: Generic reusable FD based streams 2010-09-22 18:32:21 +00:00			`^src/fdstream\.c$`
Fully asynchronous monitor I/O processing Change the QEMU monitor file handle watch to poll for both read & write events, as well as EOF. All I/O to/from the QEMU monitor FD is now done in the event callback thread. When the QEMU driver needs to send a command, it puts the data to be sent into a qemuMonitorMessagePtr object instance, queues it for dispatch, and then goes to sleep on a condition variable. The event thread sends all the data, and then waits for the reply to arrive, putting the response / error data back into the qemuMonitorMessagePtr and notifying the condition variable. There is a temporary hack in the disk passphrase callback to avoid acquiring the domain lock. This avoids a deadlock in the command processing, since the domain lock is still held when running monitor commands. The next commit will remove the locking when running commands & thus allow re-introduction of locking the disk passphrase callback * src/qemu/qemu_driver.c: Temporarily don't acquire lock in disk passphrase callback. To be reverted in next commit * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Remove raw I/O functions, and a generic qemuMonitorSend() for invoking a command * src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Remove all low level I/O, and use the new qemuMonitorSend() API. Provide a qemuMonitorTextIOProcess() method for detecting command/reply/prompt boundaries in the monitor data stream 2009-10-14 17:40:51 +00:00			`^src/qemu/qemu_monitor\.c$`

Re-write virsh console to use streams This re-writes the 'virsh console' command so that it uses the new streams API. This lets it run remotely and/or as a non-root user. This requires that virsh be linked against the simple event loop from libvirtd in daemon/event.c As an added bonus, it can now connect to any console device, not just the first one. * tools/Makefile.am: Link to event.c * tools/console.c, tools/console.h: Rewrite to use the virDomainOpenConsole() APIs with streams * tools/virsh.c: Support choosing the console name via --devname $NAME 2010-07-27 09:40:30 +00:00			`^tools/console.c$`
