[Libvir] [PATCH] NIC should define in order
by Hiroyuki Kaguchi
Currently NIC definition order is reversed.
If we set over 4-NICs for a domain by virt-install,
this causes a network communication problem.
This is because virtual mac to eth relation is lost.
This patch fixes the NIC definition order.
N.B.
If less than 3-NICs, this problem does not occur.

[Libvir] What do the docs/APIchunk*.html files do ?
by Daniel P. Berrange
Whenever we change any of the embedded API docs or add new APIs we end up
with huge diffs on the docs/APIchunk*.html files. These HTML files don't
seem to be visible anywhere on the website, nor are there even any <a href>
links to them in other pages on the website.
Can we just kill off these APIchunk* files from the doc generator in CVS
Dan.

[Libvir] PATCH: Add xstrtol variants for long long
by Daniel P. Berrange
Jim's xstrtol convenience function simplified the use of strtol, but only
support the 'int' variant. For the storage drivers I need a similar function
that will always be at minimum 64-bit since we may have files > 2 GB even
on 32-bit. So this adds a variant of the xstrtol functions which use a
long long / unsigned long long type
Regards,
Dan.

[Libvir] PATCH: RFC: env var to set default connection URI
by Daniel P. Berrange
Currently, if the app provides NULL as the connect URI, we always connect
to a Xen hypervisor.
virsh provides a VIR_DEFAULT_CONNECT_URI env var which can be used to
override this. virt-install/virt-manager never use NULL, and now try
to 'guess' a default URI based on whether /dev/kvm or /proc/xen exist.
Users have requested that VIR_DEFAULT_CONNECT_URI apply to other apps
besides virsh.
So this patch adds support for LIBVIRT_DEFAULT_URI env variable which will
be used if the connect URI is NULL. If that variable is not set it will
still default to Xen.

[Libvir] PATCH: Fix compat for Xen 3.2.0
by Daniel P. Berrange
Xen 3.2.0 removed the sockets_per_node field from the nodeinfo data returned
by XenD. I previously add compat for this, but got it in the wrong place
so it would most likely end up in a divide-by-zero error. This patch
re-arranges it to be correct.

[Libvir] PATCH: make debug builds quiet by default
by Daniel P. Berrange
During development I like to have the --enable-debug flag enabled all the
time because its very handy at times. I don't want it spewing to stderr
all the time though, just because I turned on the compile option. So this
patch adds an env variable 'LIBVIRT_DEBUG' which controls whether it is
chatty or not. So with this patch you can use --enable-debug all the time,
and just run
LIBVIRT_DEBUG=1 ./src/virsh ....
to turn it on for a particular test, or likewise for the daemon
LIBVIRT_DEBUG=1 ./qemud/libvirtd
Dan.

[Libvir] [PATCH] Update from gnulib.
by Jim Meyering
I ran ./bootstrap against a just-updated gnulib directory, so these
changes now sync into libvirt all of the changes from gnulib since
the last time:
Update from gnulib.
FYI, nearly all of these changes are also in the latest coreutils
beta/test release, so if there are problems, I should hear about
it soon.
If you'd like to see justification for a particular change,
you'll probably find it in a combination of these:
gnulib's ChangeLog file
a unit test change or addition,
a message on the bug-gnulib mailing list.

Re: [Libvir] [PATCH] python/libvir.c (VIR_PY_NONE): New macro, to encapsulate a common two-statement sequence. Handle PyTuple_New's malloc failure. Use VIR_PY_NONE.

Thanks for the review, Rich.
Seeing that messed-up Subject: line, I realized that
I sent a patch produced by "git-format-patch",
forgetting that the ancient version of mailman behind
this list would remove important parts of it.

Good idea. That makes the patch a lot bigger, but makes the
resulting code more readable, too.

Makes sense. And with VIR_PY_NONE, the duplication isn't a problem.
New patch below.

Me too.
Here's the combined patch.
Considering the number of uses of VIR_PY_NONE this introduces,
I'll have to do the right thing and split it into two: one that
adds VIR_PY_NONE, and another that fixes the NULL-deref bugs.

Handle PyTuple_New's malloc failure.
Use VIR_PY_NONE.

[Libvir] handle PyTuple_New's malloc failure
by Jim Meyering
python/libvir.c calls PyTuple_New, but doesn't handle the possibility
of a NULL return value. Subsequent use of the result pointer in e.g.,
PyTuple_SetItem, would dereference it.
This fixes most of them, but leaves the ones in
virConnectCredCallbackWrapper untouched. Fixing them
properly is not as easy, and IMHO will require actual testing.
In this patch, I combined each new test like this
((info = PyTuple_New(8)) == NULL)
with the preceding "if (c_retval < 0)", since the bodies would be the same.
Duplicating that 2-line body might look more readable,
depending on which side of the bed you get up on...
I can go either way.
Subject: [PATCH] python/libvir.c: Handle PyTuple_New's malloc failure.
