[libvirt] [PATCH 1/2] build: fix virpidfile on mingw
Regression introduced in commit b7e5ca4.
Mingw lacks kill(), but we were only using it for a sanity check;
so we can go with one less check.
Also, on OOM error, this function should outright fail rather than
claim that the pid file was successfully read.
* src/util/virpidfile.c (virPidFileReadPathIfAlive): Skip kill
call where unsupported, and report error on OOM.
---
We already skip the /proc check on non-Linux. So I say we just skip
the kill call on Win32. This stuff is only an extra sanity check
Nupon loading the pidfile, so I think returning an error is too
mean and we just skip the kill check
Done, and pushing under the build-breaker rule.
