[PATCH] rpm: drop cyrus-sasl dep
by Daniel P. Berrangé 06 Jun '24

06 Jun '24

We link to libsasl2.so, so get a dep on cyrus-sasl-libs automatically. The dep on cyrus-sasl-gssapi gets us the mechanism that matches our default config. The 'cyrus-sasl' package merely contains some man pages and the saslauthd daemon, which is not required by libvirt. This dep appears to have been redundant since we first added in commit 1b1d647439059b7e10fb94e1ade227fb695d7110 Author: Daniel P.

Schema test result can be inverted by naming the file with '-invalid.xml' suffix. In such case the test will require that the XML has invalid schema. Additionally it's also possible by adding an exception in virschematest, but we have more than a few tests with the suffix in qemuxmlconftest.

[PATCH] qemu_block: Validate number of hosts for iSCSI disk device
by Rayhan Faizel 06 Jun '24

An iSCSI device with zero hosts will result in a segmentation fault. This patch adds a check for the number of hosts, which must be one in the case of iSCSI.

[PATCH 0/2] lib: Annotate more functions as NULL terminated
by Michal Privoznik 06 Jun '24

I'm working on something that's calling qemuMonitorCreateObjectProps() and was getting random errors only to find out I was missing NULL sentinel. This sparked me to look at other functions that might be missing the G_GNUC_NULL_TERMINATED attribute too and found some.

Hello, hope it works in German. Need some help. My problem: Windows 10 won't boot anymore, automatic repair doesn't work either. Is there a way to repair Win10 and how? Best regards Gilbert Adam

[PATCH] rpm: fix setting of VIR_TEST_DEBUG
by Daniel P. Berrangé 05 Jun '24

05 Jun '24

The %meson_test macro expands to have a newline at the start, so rather than expanding to VIR_TEST_DEBUG=1 meson test .... we get VIR_TEST_DEBUG=1 meson test .... which has no effect, since VIR_TEST_DEBUG isn't exported.
