      Drop needless ret variable · 3b4df5d3
      由 Michal Privoznik 提交于 
      In few places we have the following code pattern:

  int ret;
  ... /* @ret is not accessed here */
  ret = f(...);
  return ret;

This pattern can be written less verbose:

  ...
  return f(...);

This patch was generated with following coccinelle spatch:

  @@
  type T;
  constant C;
  expression f;
  identifier ret;
  @@
  -T ret = C;
   ... when != ret
  -ret = f;
  -return ret;
  +return f;

Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

      security: Pass @migrated to virSecurityManagerSetAllLabel · 458d0a8c
      由 Michal Privoznik 提交于 
      In upcoming commits, virSecurityManagerSetAllLabel() will perform
rollback in case of failure by calling
virSecurityManagerRestoreAllLabel(). But in order to do that, the
former needs to have @migrated argument so that it can be passed
to the latter.

      build: remove use of usleep gnulib module in favour of g_usleep · 27cb4c1a
      由 Daniel P. Berrangé 提交于 
      The usleep function was missing on older mingw versions, but we can rely
on it existing everywhere these days. It may only support times upto 1
second in duration though, so we'll prefer to use g_usleep instead.

The commandhelper program is not changed since that can't link to glib.
Fortunately it doesn't need to build on Windows platforms either.

      build: link to glib library · cfbe9f12
      由 Daniel P. Berrangé 提交于 
      Add the main glib.h to internal.h so that all common code can use it.

Historically glib allowed applications to register an alternative
memory allocator, so mixing g_malloc/g_free with malloc/free was not
safe.

This was feature was dropped in 2.46.0 with:

      commit 3be6ed60aa58095691bd697344765e715a327fc1
      Author: Alexander Larsson <alexl@redhat.com>
      Date:   Sat Jun 27 18:38:42 2015 +0200

        Deprecate and drop support for memory vtables

Applications are still encourged to match g_malloc/g_free, but it is no
longer a mandatory requirement for correctness, just stylistic. This is
explicitly clarified in

    commit 1f24b36607bf708f037396014b2cdbc08d67b275
    Author: Daniel P. Berrangé <berrange@redhat.com>
    Date:   Thu Sep 5 14:37:54 2019 +0100

        gmem: clarify that g_malloc always uses the system allocator

Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.

This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.

This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.

Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.

      conf: utility function to update entry in def->nets array · 7e490cda
      由 Laine Stump 提交于 
      A virDomainNetDef object in a domain's nets array might contain a
virDomainHostdevDef, and when this is the case, the domain's hostdevs
array will also have a pointer to this embedded hostdev (this is done
so that internal functions that need to perform some operation on all
hostdevs won't leave out the type='hostdev' network interfaces).

When a network device was updated with virDomainUpdateDeviceFlags(),
we were replacing the entry in the nets array (and free'ing the
original) but forgetting about the pointer in the hostdevs array
(which would then point to the now-free'd hostdev contained in the old
net object.) This often resulted in a libvirtd crash.

The solution is to add a function, virDomainNetUpdate(), called by
qemuDomainUpdateDeviceConfig(), that updates the hostdevs array
appropriately along with the nets array.
