[PATCH 1/3] rpc: mark GSourceFuncs functions in vireventglibwatch.c as static
by Fima Shevrin
From: "Denis V. Lunev" <den(a)openvz.org>
They are not exported from the module and thus should be static.

[PATCH (pushed)] qemuDomainBlockPeek: Fix format checking logic
by Peter Krempa
Recent refactor which changed the format check to use
qemuBlockStorageSourceIsRaw accidentaly inverted the condition.
Caught by the CI test suite.

Ok, this thread is the primary one responsible for I/O. It is
waiting, while not holding any mutex.

This is a second API call that has arrived and has queued its outgoing
message, and is waiting either for the other thread to pass ownership
of the socket to it, or for the other thread to provide its reply (whichever
comes first).
This is all totally normal, and working as expected, so I still
don't see what the actual problem is ?

What behaviour are you expecting this demo program to show ?
When I run it, the VM starts and the the dev caps listing is
then run 3 seconds later (due to the sleep). Removing the
sleep, I can see the caps list running in parallel with the
'create'.
Basically I see nothing wrong.
With regards,
Daniel

At our opinion the problem here is missed wakeup from
the side thread to the main thread.
In the original code, i.e. before switching to the main_loop,
the problem was not occurred as wakeup event was kept inside
the pipe and the poll has been immediately woken up.
I have written the same code with pipes but that code is
a bit cumbersome due to the Windows compatibility. Thus
this application with Prepare seems cleaner.

[PATCH] CIM: Include <stdlib.h> in libxkutil for malloc functions
by Florian Weimer
This avoids implicit function declarations and build failures with
future compilers.
Not sure where to submit this. Our Fedora package references
<http://libvirt.org/CIM/>, but it's 404, and I can't find a CIM
component in the Gitlab organization.
Thanks,
Florian

Public virErrorPreserveLast()/virErrorRestore()
by John Levon
These two functions are currently private to libvirt, hence not available to
consumers. Would it be possible to make them public? Without them, there's no
way to do any libvirt call without stomping on an existing error that you may
want to preserve.
I have multiple threads sharing a remote connection (to local libvirtd). I need
to be able to handle connection drops (e.g. libvirtd restart). Long story short,
the only approach I've found that actually works properly is that there's one
main conn object, each thread has a virConnectRef() to it, and whenever a thread
gets an error, we check in the error callback if !virConnectIsAlive(). If so, we
close the thread's conn, and potentially also clean up the main conn.
Then when the error gets returned from the relevant library call, we try to
re-connect.
However, virConnectIsAlive() stomps on the thread's error, meaning we lose the
context on a real, non-connection-related error.
So I need to be able to save and restore in the error handler.
Given how much these are used inside libvirt code already, it feels likely it
would be useful in other public cases too.
Thoughts?

[PATCH v2 0/3] Rework main and side threads interaction in rpc
by Fima Shevrin
From: "Fima Shevrin" <efim.shevrin(a)virtuozzo.com>
RPC client implementation uses the following paradigm. The critical
section is organized via virObjectLock(client)/virObjectUnlock(client)
braces. Though this is potentially problematic as
main thread: side thread:
virObjectUnlock(client);
virObjectLock(client);
g_main_loop_quit(client->eventLoop);
virObjectUnlock(client);
g_main_loop_run(client->eventLoop);
This means in particular that is the main thread is executing very long
request like VM migration, the wakeup from the side thread could be
stuck until the main request will be fully completed.
Discrubed case is easily reproducible with the simple python scripts doing slow
and fast requests in parallel from two different threads.
Our idea is to release the lock at the prepare stage and avoid libvirt stuck
during the interaction between main and side threads.
Changes: Add cover letter and versions

Subject: [PATCH v2 1/3] rpc: mark GSourceFuncs functions in vireventglibwatch.c
as static
They are not exported from the module and thus should be static.
