      util: replace strerror/strerror_r with g_strerror · c4d18e8b
      由 Daniel P. Berrangé 提交于 
      g_strerror is offers the safety/correctness benefits of strerror_r, with
the API design convenience of strerror.

Use of virStrerror should be eliminated through the codebase in favour
of g_strerror.

commandhelper.c is a special case as its a tiny single threaded test
program, not linked to glib, so it just uses traditional strerror().

      src: add support for g_autoptr with virObject instances · 667ff797
      由 Daniel P. Berrangé 提交于 
      Libvirt currently uses the VIR_AUTOUNREF macro for auto cleanup of
virObject instances. GLib approaches things differently with GObject,
reusing their g_autoptr() concept.

This introduces support for g_autoptr() with virObject, to facilitate
the conversion to GObject.

Only virObject classes which are currently used with VIR_AUTOREF are
updated. Any others should be converted to GObject before introducing
use of autocleanup.

      util: rewrite auto cleanup macros to use glib's equivalent · 44e7f029
      由 Daniel P. Berrangé 提交于 
      To facilitate porting over to glib, this rewrites the auto cleanup
macros to use glib's equivalent.

As a result it is now possible to use g_autoptr/VIR_AUTOPTR, and
g_auto/VIR_AUTOCLEAN, g_autofree/VIR_AUTOFREE interchangably, regardless
of which macros were used to declare the cleanup types.

Within the scope of any single method, code must remain consistent
using either GLib or Libvirt macros, never mixing both. New code
must preferentially use the GLib macros, and old code will be
converted incrementally.

      Convert the string duplication APIs to use the g_strdup family of APIs.

We previously used the 'strdup-posix' gnulib module because mingw does
not set errno to ENOMEM on failure

We previously used the 'strndup' gnulib module because this function
does not exist on mingw.

We previously used the 'vasprintf' gnulib module because of many GNU
supported format specifiers not working on non-Linux platforms. glib's
own equivalent standardizes on GNU format specifiers too.

      Convert the VIR_ALLOC family of APIs with use of the g_malloc family of

out over time, allowing return value checks to be dropped. Use of
VIR_FREE should be replaced with auto-cleanup whenever possible.

      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.

      src: Make virStr*cpy*() functions return an int · 6c0d0210
      由 Andrea Bolognani 提交于 
      Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.

Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.

Change the functions so that they return an int
instead.
