[libvirt] [PATCH 0/2] Fix virGetUserXXXDirectory on Win32
by Daniel P. Berrange 24 May '12

24 May '12

The newly added APIs for getting user directories were causing a win32 build failure, due to export of non-existing APIs. The build fix is complicated enough that it needs review.

[libvirt] [PATCH][libvirt-glib] Don't misuse GMainLoop for libvirt event loop
by Michal Privoznik 24 May '12

24 May '12

Since we are calling APIs within timers, those might block as any libvirt API may block. This, however, might get so critical, that server will shut us down due to timeout on keepalive. Simply, if an API called within a timer block, entire event loop is blocked and no keepalive response can be sent. Therefore, delegate separate thread for such purpose. --- For some reason LibvirtGObject-1.0.gir generation fails with this from time to time. examples/event-test.c | 4 +- libvirt-glib/libvirt-glib-event.c | 474 +++++++------------------------- libvirt-glib/libvirt-glib-event.h | 3 +- libvirt-glib/libvirt-glib.sym | 5 + libvirt-gobject/libvirt-gobject-main.c | 3 +- python/libvirt-glib.c | 23 ++- 6 files changed, 129 insertions(+), 383 deletions(-) diff --git a/examples/event-test.c b/examples/event-test.c index 7c9f4ec..ccb8f9e 100644 --- a/examples/event-test.c +++ b/examples/event-test.c @@ -166,7 +166,8 @@ int main(int argc, char **argv) } loop = g_main_loop_new(g_main_context_default(), 1); - gvir_event_register(); + if (gvir_event_register() != TRUE) + return -1; virConnectPtr dconn = NULL; dconn = virConnectOpen (argv[1] ? argv[1] : NULL); @@ -185,6 +186,7 @@ int main(int argc, char **argv) if (virConnectClose(dconn) < 0) printf("error closing\n"); + gvir_event_deregister(); printf("done\n"); return 0; diff --git a/libvirt-glib/libvirt-glib-event.c b/libvirt-glib/libvirt-glib-event.c index 94f4de8..d3cf7c3 100644 --- a/libvirt-glib/libvirt-glib-event.c +++ b/libvirt-glib/libvirt-glib-event.c @@ -33,7 +33,7 @@ /** * SECTION:libvirt-glib-event - * @short_description: Integrate libvirt with the GMain event framework + * @short_description: Implement libvirt event loop * @title: Event loop * @stability: Stable * @include: libvirt-glib/libvirt-glib.h @@ -41,22 +41,23 @@ * The libvirt API has the ability to provide applications with asynchronous * notifications of interesting events.
