2016-10-27char: set name for all I/O channels createdDaniel P. Berrange
Ensure that all I/O channels created for character devices are given names to distinguish their respective roles. Acked-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2016-10-27io: add ability to set a name for IO channelsDaniel P. Berrange
The GSource object has ability to have a name, which is useful when debugging performance problems with the mainloop event callbacks that take too long. By associating a name with a QIOChannel object, we can then set the name on any GSource associated with the channel. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

2016-08-19glib: add compatibility implementation for g_dir_make_tmp()Sascha Silbe
We're going to make use of g_dir_make_tmp() in test-logging. Provide a compatibility implementation of it for glib < 2.30. May behave differently in some edge cases (e.g. pattern only at the end of the template, the file name is not part of the error message), but good enough in practice.

2015-05-08glib-compat.h: change assert to g_assertMichael Tokarev
include/glib-compat.h defines a bunch of functions based on glib primitives, and uses assert() without including assert.h. Replace assert() with g_assert() to make the file more self-contained, and to fix compilation breakage after 28507a415a9b1e.

2015-04-02glib-compat: fix problems with not-quite glib 2.22Cornelia Huck
Commit 89b516d8b9444ece8ccabb322a9389587c7a7b83 ("glib: add compatibility interface for g_get_monotonic_time()") aimed at making qemu build with old glib versions. At least SLES11SP3, however, contains a backport of g_get_monotonic_time() while keeping the reported glib version at 2.22. Let's work around this by a strategically placed #define.

This patch fixes compilation errors when building against glib <2.28.0 due to the missing g_get_monotonic_time() function. The compilation error in tests/libqos/virtio.c was introduced in commit 70556264a89a268efba1d7e8e341adcdd7881eb4 ("libqos: use microseconds instead of iterations for virtio timeout").

2014-06-10glib-compat.h: add new thread API emulation on top of pre-2.31 APIMichael Tokarev
Thread API changed in glib-2.31 significantly. Before that version, conditionals and mutexes were only allocated dynamically, using _new()/_free() interface. in 2.31 and up, they're allocated statically as regular variables, and old interface is deprecated. (Note: glib docs says the new interface is available since version 2.32, but it was actually introduced in version 2.31). Create the new interface using old primitives, by providing non-opaque definitions of the base types (GCond and GMutex) using GOnces. Replace #ifdeffery around GCond and GMutex in trace/simple.c and coroutine-gthread.c too because it does not work anymore with the new glib-compat.h.

2014-05-09glib: fix g_poll early timeout on windowsSangho Park
g_poll has a problem on Windows when using timeouts < 10ms, in glib/gpoll.c: /* If not, and we have a significant timeout, poll again with * timeout then. Note that this will return indication for only * one event, or only for messages. We ignore timeouts less than * ten milliseconds as they are mostly pointless on Windows, the * MsgWaitForMultipleObjectsEx() call will timeout right away * anyway. */ if (retval == 0 && (timeout == INFINITE || timeout >= 10)) retval = poll_rest (poll_msgs, handles, nhandles, fds, nfds, timeout); so whenever g_poll is called with timeout < 10ms it does a quick poll instead of wait, this causes significant performance degradation of QEMU, thus we should use WaitForMultipleObjectsEx directly Signed-off-by: Stanislav Vorobiov <s.vorobiov@samsung.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
