Adding an exception for the whole file usually defeats the purpose of a

removed.
In case of the suggestion of using 'safewrite' instead of write even the
comment for safewrite states that the function needs to be used only in
certain cases.
Remove the blanket exceptions for files and use an exclude string
instead. The only instance where we keep the full file exception is for
src/libvirt-stream.c as there are multiple uses in example code in
comments where I couldn't find a nicer targetted wapproach.

An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change. It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome. To make sure the behaviour does not change
specify the parameter explicitly. In places where we check for the return code
the parameter should be 'false' so that meson does not fail. In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.
The warning in meson was added in https://github.com/mesonbuild/meson/pull/9304

Add support for deserializing the binary PCI/PCIe VPD format and storing
results in memory.
The VPD format is specified in "I.3. VPD Definitions" in PCI specs
(2.2+) and "6.28.1 VPD Format" PCIe 4.0. As section 6.28 in PCIe 4.0
notes, the PCI Local Bus and PCIe VPD formats are binary compatible
and PCIe 4.0 merely started incorporating what was already present in
PCI specs.
Linux kernel exposes a binary blob in the VPD format via sysfs since
v2.6.26 (commit 94e6108803469a37ee1e3c92dafdd1d59298602f) which requires

macOS is similar to FreeBSD in that it ships non-GNU versions

macOS actually includes GNU make already, but unfortunately due
to licensing reasons the tool is permanently stuck in 2006, so
even in that case users are better off installing a recent
version from Homebrew along with the dozens of other libvirt
dependencies that already need to be obtained that way.
Note that, unlike FreeBSD ports, Homebrew is fully consistent
in adding the 'g' prefix to the name of the GNU tools, so we

The aim of virSecurity rule is to discourage from using plain
virSecurityManager*() APIs within QEMU driver in favor of their
qemuSecurity*() counterparts. The reason is simple: namespaces;
virSecurityManager*() needs additional
virSecurityManagerTransactionCommit() call to enter given
namespace and do its work from there. And that's exactly what
those qemuSecurity*() wrappers do.
To help us ensure correctness (from this POV), we have a
syntax-check rule that forbids any occurrence of
"virSecurityManager" string under src/qemu/ (except for
qemu_security of course).
But with if we want to remove virSecurityManagerPtr type, then we
have to allow "virSecurityManager *". Therefore, change the rule
so that no call of a function with "virSecurityManager" prefix is
allowed. And also change the name to better reflect what is going

Trying to report an OOM error is pointless since our infrastructure to
report error needs to allocate memory to report the error.
In addition our code mistakenly reported OOM errors even in cases where
a function could fail for another reason, which would make issues harder
to debug.
Remove the virReportOOMError and backend so that programmers are forced
to think about what can happen. In case when there's another failure
possible a specific error should be reported and otherwise a direct
abort() is better since the logger would abort on g_new anyways.
This patch also removes the syntas-check which forces use of
virReportOOMError instead of using VIR_ERR_NO_MEMORY with other
functions. This allows possible future use when we'd end up in a
situation where trying to recover from an OOM would make sense, such as
when attempting to allocate a massive buffer.
