[libvirt] [jenkins-ci PATCH] guests: Stop using search() as a filter
by Andrea Bolognani 13 Jul '18

13 Jul '18

Recent versions of Ansible complain about this, and suggest to replace 'result|search' with 'result is search'. Since f17097c7af59, however, we've been including operating system information in the inventory: this allows us to drop our use of search() entirely.

[libvirt] [PATCH v2 0/2] test: Implement virConnectListAllNodeDevices
by Cole Robinson 13 Jul '18

13 Jul '18

v1: https://www.redhat.com/archives/libvir-list/2018-February/msg01135.html virnodedeviceobj.c generic ListAll infrastructure is not stateless and will try to refresh nodedev scsi/pci/etc. config. Understandable this doesn't play well with the test driver. Trying to untangle it is a bit tough though. This series adds a way to skip touching the host so we can implement ListAllDevices in the test driver, which we want for virt-manager and libvirt-dbus test suites Cole Robinson (2): conf: nodedev: Don't refresh host caps in testdriver test: Implement virConnectListAllNodeDevices src/conf/virnodedeviceobj.c | 13 ++++++++++++- src/conf/virnodedeviceobj.h | 4 ++++ src/test/test_driver.c | 15 +++++++++++++++ 3 files changed, 31 insertions(+), 1 deletion(-) -- 2.17.1

[libvirt] [PATCH v3 00/35] use GNU C's cleanup attribute in src/util (batch I)
by Sukrit Bhatnagar 13 Jul '18

13 Jul '18

This series of patches first introduces a new set of macros which help in using GNU C's __attribute__((cleanup)) in the code. Then a few syntax-check rules are added which help in ensuring correct usage of the newly introduced cleanup macros. Then the patches modify a few files in src/util to use VIR_AUTOFREE and VIR_AUTOPTR for automatic freeing of memory and get rid of some VIR_FREE macro invocations and *Free function calls.
