The current qemudRegisterClientEvent() code is used both for
registering the initial socket watch, and updating the already
registered watch. This causes unneccessary complexity in alot
of code which only cares about updating existing watches. The
updating of a watch cannot ever fail, nor is a reference to the
'qemud_server' object required.
This introduces a new qemudUpdateClientEvent() method for that
case, allowing the elimination of unneccessary error checking
and removal of the server back-reference in struct qemud_client.
* qemud/qemud.h: Remove 'server' field from struct qemud_client.
Add qemudUpdateClientEvent() method. Remove 'update' param
from qemudRegisterClientEvent method
* qemud/dispatch.c, qemud/qemud.c, qemud/remote.c: Update alot
of code to use qemudUpdateClientEvent() instead of
qemudRegisterClientEvent(). Move more logic from remoteRelayDomainEvent
into remoteDispatchDomainEventSend.
Separate the decoding of incoming request header out from the
dispatch code. This will allow later code to making dispatcher
routing decisions based on the header field data.
* qemud/dispatch.c, qemud/dispatch.h: Add remoteDecodeClientMessageHeader
API for decoding the header of a client message. Update the
remoteDispatchClientRequest method to assume a pre-decoded
header.
* qemud/qemud.h: Include a 'remote_message_header' field in
'struct qemud_client_message' for pre-decoded header data
* qemud/qemud.c: Decode the incoming client message header before
invoking remoteDispatchClientRequest
Before this change, the unix socket directory was hard-coded
to be e.g., /var/run/libvirt for euid==0 and ~/.libvirt otherwise.
With this change, you may now specify that directory in libvirtd's
config file via a line like this: unix_sock_dir = "/var/run/libvirt".
This is essential for running tests that do not impinge on any
existing libvirtd process, and in running tests in parallel.
* qemud/libvirtd.conf (unix_sock_dir): Add comment and example.
* qemud/qemud.h (struct qemud_server) [logDir]: Change type
from char[PATH_MAX] to char*.
* qemud/qemud.c (unix_sock_dir): New global
(remoteReadConfigFile): Set the global.
(qemudInitPaths): Use the global, unix_sock_dir, if non-NULL.
One minor improvement: unlink both sockets or none, never
just one of them.
(qemudCleanup): Free logDir.
(main): Use the new global rather than hard-coding "/run/libvirt".
* qemud/libvirtd.aug (sock_acl_entry): Add "unix_sock_dir".
* src/socketcompat.h: Remove file.
* src/remote_internal.c: Don't include socketcompat.h.
* qemud/qemud.h: Likewise.
* qemud/remote_protocol.x: Likewise, but do include <arpa/inet.h>
for htonl.
* src/remote_internal.c: Likewise, but do include <errno.h>.
* qemud/remote_protocol.c: Regenererate.
* qemud/remote_protocol.h: Regenererate.
* src/Makefile.am (REMOTE_DRIVER_SOURCES): Remove socketcompat.h.
