[libvirt] [PATCH 0/7] Introduce automatic clearing for virBuffer
by Peter Krempa
First 4 patches clean up existing mess.
Note that this series both fixes and then deletes virBufferEscapeN.
The split is deliberate, so that if somebody needs virBufferEscapeN
in the future they can revert the removal and get a working version.
Peter Krempa (7):
util: buffer: Remove misleading AUTOPTR func for 'virBuffer'
util: buf: Fix memory leak in virBufferEscapeN
tests: buf: Fix debug messages in 'testBufEscapeRegex'
util: buf: Remove virBufferEscapeN
util: alloc: Introduce 'VIR_AUTOCLEAN' macros for clearing stack'd
structs
util: buffer: Introduce VIR_AUTOCLEAN function for virBuffer
qemu: domain: Use VIR_AUTOCLEAN for virBuffer

[libvirt] [PATCHv2 0/2] network: add netmask to dhcp range of dnsmasq conf file for IPv4
by Laine Stump
I sent V1 of this patch way back in October:
https://www.redhat.com/archives/libvir-list/2018-October/msg00889.html
but then self-NACKed it because I had written the patch to add the
network prefix to dhcp-range, but IPv4 requires the netmask rather
than range. Unfortunately, when I modified the patch accordingly the
getnameinfo() function began failing, I couldn't immediately see why,
and I had to pack everything up and go to KVM Forum. After that, I
promptly forgot to look back at it.
Today I finally revisited the problem (after the person who originally
found it sent a reminder), and discovered the failure of getnameinfo()
was due to a bug in a function that I added to the virSocketAddr
library in 2010!

[libvirt] [PATCH 0/7] bulk snapshot list/redefine (incremental backup saga)
by Eric Blake
While looking at my work on incremental backups, Nir raised a good
point: if we want to recreate a set of known checkpoints on one
machine that will be taking over a domain from another machine,
my initial proposal required making multiple API calls to list the
XML for each checkpoint on the source, and then more API calls to
redefine each checkpoint on the destination; it also had the drawback
that the list has to be presented in topological order (the API won't
let you define a child checkpoint if the parent is not defined first).
He asked if I could instead add bulk APIs, for getting the XML for
all checkpoints at once, and then for redefining all checkpoints at
once.
Since my checkpoint code borrows heavily from concepts in the snapshot
code, I chose to tackle the problem by starting with this series, which
does the same thing for snapshots as what I plan to do for checkpoints.
That is, since this patch series adds virDomainGetXMLDesc(,
VIR_DOMAIN_XML_SNAPSHOTS) and virDomainSnapshotCreateXML(,
VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE_LIST), the checkpoint series
will add virDOmainGetXMLDesc(, VIR_DOMAIN_XML_CHECKPOINTS) and
virDomainCheckpointCreateXML(, VIR_DOMAIN_CHECKPOINT_CREATE_REDEFINE_LIST)
with very similar code.
Note that I'm posting the series now to start review; the bulk
query is fully implemented (patch 6), while the bulk redefine still
needs more work (patch 7 defines the API, but the actual implementation
is trickier, so I'll be posting additional patches later once I get
them working). Patch 1 is a revision of work posted previously in a
different series where all other patches of that series are now on
mainline. Also available at:
https://repo.or.cz/libvirt/ericb.git/shortlog/refs/tags/snapshot-bulk-v1

[libvirt] [PATCH] snapshot: Saner use of uuid
by Eric Blake
Most of the code base is fairly consistent about using the name
'uuidstr' when dealing with a formatted human-readable form, and
'uuid' when dealing with the smaller raw bytes form. Fix
snapshot_conf to comply, as well as reducing the scope of a human
string to only the error message that needs it.

[libvirt] libvirt 'make cov' vs gnulib 'make coverage'
by Cole Robinson
Recently I've played with libvirt coverage/gcov/lcov support. The
libvirt specific way to enable it is:
./configure --enable-test-coverage
make check
make cov
firefox coverage/index.html
However it looks like gnulib provides an automagic way to get similar
output. The process is:
make coverage
firefox doc/coverage/index.html
'make coverage' is composed of these 3 additional commands:
make init-coverage # clear lcov counters
make build-coverage # 'make check' with coverage flags, generate
# lcov metadata
make gen-coverage # generate the html report
It seems like we can just drop our custom coverage implementation.
* Less code for us
* The gnulib implementation is more flexible with the split commands
* libvirt impl needs an explicit directory list. right now gnulib output
reports info for the tools/ dir but libvirt's doesn't
* gnulib impl doesn't require a reconfigure
* seems like libvirt impl never calls lcov --zerocounters which AFAICT
means that every 'make check' run adds to the coverage stats. so if
you wanted to check for coverage changes across commits we require a
make clean in between to zero out the stats for testing. gnulib
init-coverage takes care of that.
Anyone know a reason not to rip this out? If not I'll send a patch
Thanks,
Cole

[libvirt] [PATCH v3 00/17] qemu: virtio-{non-}transitional support
by Cole Robinson
v2 libvirt patches:
https://www.redhat.com/archives/libvir-list/2019-January/msg00877.html
v1 libvirt patches:
https://www.redhat.com/archives/libvir-list/2019-January/msg00593.html
Previous incomplete RFC here:
https://www.redhat.com/archives/libvir-list/2019-January/msg00346.html
qemu patches, queued for qemu 4.0.0:
https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg00923.html
Previous libvirt discussion around this:
https://www.redhat.com/archives/libvir-list/2018-August/msg01073.html
Changes since v2:
* Some prep patches merged
* filesystem model dropped the -9p naming, now uses virtio-{non-}transitional
like other devices
* Now uses a single capability QEMU_CAPS_VIRTIO_PCI_NON_TRANSITIONAL
which is set whenever any of the -transitional or -non-transitional
devices are present.
* Add a formatdomain section 'Virtio transitional devices' and reference
it from each relevant device section
* if virtio-transitional specified, and qemu is too old but has the
disable_X options, convert it to explicit
disable-legacy=off,disable-modern=off
* Misc small changes pointed out in review
Thanks,
Cole
