[libvirt] Hidden symbols
by Shradha Shah
Hello All,
When using a systemtap to get a call chain of functions that are executed during the migration of a vm from one host to another I realised that many of the symbols in libvirt are hidden and not visible to systemtap.
Is there a way I can make all the symbols visible just for debugging purposes?
Many Thanks,
Regards,
Shradha Shah

[libvirt] [PATCH] Fix rpc generator to anchor matches for method names
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The RPC generator transforms methods matching certain
patterns like 'id' or 'uuid', etc but does not anchor
its matches to the end of the word. So if a method
contains 'id' in the middle (eg virIdentity) then the
RPC generator munges that.
* src/rpc/gendispatch.pl: Anchor matches

[libvirt] [PATCH 0/4] Misc patches to support RBAC work
by Daniel P. Berrange
The following patches aren't really needed on their own, rather
they are part of the role based access control work I'm doing.
In order to keep my patch queue small, I'm sending these out
now, since there is no harm in merging them

[libvirt] [PATCH] errors: Improve error reporting to log multiple errors instead of just the last one
by Michal Novotny
This patch introduces a new structure called virErrorsPtr which can get all
the errors that occurred since the connection open. The error callback function
is being used as many times as necessary. The new public function called
virGetAllErrors() has been introduced to get all the errors that occurred.
Also, a new test called errorreport has been written to test the functionality
of error logging for multiple error occurrences.
