9b80e0c12a util: drop support for stack traces with logging
The log filters have supported the use of a "+" before the source match
string to request that a stack trace be emitted for every log message:

  commit 548563956e
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Wed May 9 15:18:56 2012 +0100

    Allow stack traces to be included with log messages

    Sometimes it is useful to see the callpath for log messages.
    This change enhances the log filter syntax so that stack traces
    can be show by setting '1:+NAME' instead of '1:NAME'.

With the huge & ever increasing number of logging statements per file,
this will be incredibly verbose and have a major performance penalty.
This makes the feature impractical to use widely and as such it is not
worth the code maint cost.

Removing this seldom used feature allows us to drop the 'execinfo'
module in gnulib which provides the backtrace() function which doesn't
exist on non-Linux.

Users who want to get stack traces of parts of libvirt can use GDB,
or systemtap for live tracing with minimal perf impact.

667ff797e8 src: add support for g_autoptr with virObject instances
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.

44e7f02915 util: rewrite auto cleanup macros to use glib's equivalent
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.

cfbe9f1201 build: link to glib library
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>

        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.

557ac8cbf5 docs: attempt to document the general libvirt dev strategy
There are various ideas / plans floating around for future libvirt work,
some of which is actively in progress. Historically we've never captured
this kind of information anywhere, except in mailing list discussions.
In particular guidelines in hacking.html.in don't appear until a policy
is actively applied.

This patch attempts to fill the documentation gap, by creating a new
"strategy" page which outlines the general vision for some notable
future changes. The key thing to note is that none of the stuff on this
page is guaranteed, plans may change as new information arises. IOW this
is a "best guess" as to the desired future.

This doc has focused on three areas, related to the topic of language
usage / consolidation

 - Use of non-C languages for the library, daemons or helper tools
 - Replacement of autotools with meson
 - Use of RST and Sphinx for documentation (website + man pages)

ada268012a build: force a UTF-8 locale for python
Python3 versions less than 3.7 have very unhelpful handling
of the C locale where they assume data is 7-bit only. This
violates POSIX which requires the C locale to be 8-bit clean.
Python3 >= 3.7 now assumes that the C locale is always UTF-8.

Set env variables to force LC_CTYPE to en_US.UTF-8 so that
we get UTF-8 handling on all python versions. Note we do
not use C.UTF-8 since not all C libraries support that.

77f72a8615 conf: new "managed" attribute for target dev of <interface type='ethernet'>
Although <interface type='ethernet'> has always been able to use an
existing tap device, this is just a coincidence due to the fact that
the same ioctl is used to create a new tap device or get a handle to
an existing device.

Even then, once we have the handle to the device, we still insist on
doing extra setup to it (setting the MAC address and IFF_UP).  That
*might* be okay if libvirtd is running as a privileged process, but if
libvirtd is running as an unprivileged user, those attempted
modifications to the tap device will fail (yes, even if the tap is set
to be owned by the user running libvirtd). We could avoid this if we
knew that the device already existed, but as stated above, an existing
device and new device are both accessed in the same manner, and
anyway, we need to preserve existing behavior for those who are
already using pre-existing devices with privileged libvirtd (and
allowing/expecting libvirt to configure the pre-existing device).

In order to cleanly support the idea of using a pre-existing and
pre-configured tap device, this patch introduces a new optional
attribute "managed" for the interface <target> element. This
attribute is only valid for <interface type='ethernet'> (since all
other interface types have mandatory config that doesn't apply in the
case where we expect the tap device to be setup before we
get it). The syntax would look something like this:

   <interface type='ethernet'>
      <target dev='mytap0' managed='no'/>
      ...
   </interface>

This patch just adds managed to the grammar and parser for <target>,
but has no functionality behind it.

(NB: when managed='no' (the default when not specified is 'yes'), the
target dev is always a name explicitly provided, so we don't
auto-remove it from the config just because it starts with "vnet"
(VIR_NET_GENERATED_TAP_PREFIX); this makes it possible to use the
same pattern of names that libvirt itself uses when it automatically
creates the tap devices.)

926b7b6e6c docs: remove devhelp API docs
We currently generate two completely separate API references for the
libvirt public API. One at 'docs/html/' and one at 'docs/devhelp/'.
Both are published on the website, but we only link to content in
the 'docs/html/' pages.

Both are installed in the libvirt-docs sub-RPM, with a full copy
of the website including 'docs/html/' in /usr/share/docs/libvirt-docs,
while the 'docs/devhelp/' content goes to /usr/share/gtk-doc/. The
latter was broken for years until:

  commit ca6f602546
  Author: Andrea Bolognani <abologna@redhat.com>
  Date:   Fri May 10 14:54:52 2019 +0200

    docs: Introduce $(devhelphtml_generated)

    Our XSLT magic generates one Devhelp-compatible HTML file
    per documentation module, but so far we have only shipped
    and installed documentation for virterror.

    Now that we have $(modules), however, we can generate the
    list of files the same way we do for regular documentation
    and make sure we always ship and install everything.

That this bug went unnoticed for so long is a sign of how few
people are using the devhelp docs. The only commits to the devhelp
code since it was first introduced have been fixing various build
problems that hit.

The only obvious difference between the two sets of docs is the CSS
styling in use. Overall devhelp does not look compelling enough to
justify having two duplicated sets of API docs. Eliminating it will
reduce the amount of XSL code we are carrying in the tree which is
an attractive benefit.

QEMU version 2.12.1 introduced a performance feature under commit

This patch adds a new KVM feature 'hint-dedicated' to set this performance
hint for KVM guests. The feature is off by default.

To enable this hint and have libvirt add "-cpu host,kvm-hint-dedicated=on"
to the QEMU command line, the following XML code needs to be added to the
guest's domain description in conjunction with CPU mode='host-passthrough'.

  <features>

b18c273a24 remote: enable connecting to the per-driver daemons
Historically URIs handled by the remote driver will always connect to
the libvirtd UNIX socket. There will now be one daemon per driver, and
each of these has its own UNIX sockets to connect to.

It will still be possible to run the traditional monolithic libvirtd
though, which will have the original UNIX socket path.

In addition there is a virproxyd daemon that doesn't run any drivers,
but provides proxying for clients accessing libvirt over IP sockets, or
tunnelling to the legacy libvirtd UNIX socket path.

Finally when running inside a daemon, the remote driver must not reject
connections unconditionally. For example, the QEMU driver needs to be
able to connect to the network driver. The remote driver must thus be
willing to handle connections even when inside the daemon, provided no
local driver is registered.

This refactoring enables the remote driver to be able to connect to the
per-driver daemons. The URI parameter "mode" accepts the values "auto",
"direct" and "legacy" to control which daemons are connected to.

The client side libvirt.conf config file also supports a "remote_mode"
setting which is used if the URI parameter is not set.

If neither the config file or URI parameter set a mode, then "auto"
is used, whereby the client looks to see which sockets actually exist
right now.

The remote driver will only ever spawn the per-driver daemons, or
the legacy libvirtd. It won't ever try to spawn virtproxyd, as
that is only there for IP based connectivity, or for access from
legacy remote clients.

If connecting to a remote host over any kind of ssh tunnel, for now we
must assume only the legacy socket exists. A future patch will introduce
a netcat replacement that is tailored for libvirt to make remote
tunnelling easier.

The configure arg '--with-remote-default-mode=legacy|direct' allows
packagers to set a default at build time. If not given, it will default
to legacy mode.

Eventually the default will switch to direct mode. Distros can choose
to do the switch earlier if desired. The main blocker is testing and
suitable SELinux/AppArmor policies.

d19c21429f virpci: Allow greater PCI domain value in virPCIDeviceAddressIsValid
There is no restriction on maximum value of PCI domain. In fact,
Linux kernel uses plain atomic inc when assigning PCI domains:

drivers/pci/pci.c:static int pci_get_new_domain_nr(void)
drivers/pci/pci.c-{
drivers/pci/pci.c-      return atomic_inc_return(&__domain_nr);
drivers/pci/pci.c-}

Of course, this function is called only if kernel was compiled
without PCI domain support or ACPI did not provide PCI domain.

However, QEMU still has the same restriction as us: in
set_pci_host_devaddr() QEMU checks if domain isn't greater than
0xffff. But one can argue that that's a QEMU limitation. We still
want to be able to cope with other hypervisors that don't have
this limitation (possibly).

0d44788fc3 backup: Introduce virDomainCheckpoint APIs
Introduce a bunch of new public APIs related to backup checkpoints.
Checkpoints are modeled heavily after virDomainSnapshotPtr (both
represent a point in time of the guest), although a snapshot exists
with the intent of rolling back to that state, while a checkpoint
exists to make it possible to create an incremental backup at a later
time.  We may have a future hypervisor that can completely manage
checkpoints without libvirt metadata, but the first two planned
hypervisors (qemu and test) both always use libvirt for tracking
metadata relations between checkpoints, so for now, I've deferred
the counterpart of virDomainSnapshotHasMetadata for a separate
API addition at a later date if there is ever a need for it.

Note that until we allow snapshots and checkpoints to exist
simultaneously on the same domain (although the actual prevention of
this will be in a separate patch for the sake of an easier revert down
the road), that it is not possible to branch out to create more than
one checkpoint child to a given parent, although it may become
possible later when we revert to a snapshot that coincides with a
checkpoint.  This also means that for now, the decision of which
checkpoint becomes the parent of a newly created one is the only
checkpoint with no child (so while there are APIs for dealing with a
current snapshot, we do not need those for checkpoints).  We may end
up exposing a notion of a current checkpoint later, but it's easier to
add stuff when proven needed than to blindly support it now and wish
we hadn't exposed it.

The following map shows the API relations to snapshots, with new APIs
on the right:

Operate on a domain object to create/redefine a child:
virDomainSnapshotCreateXML          virDomainCheckpointCreateXML

Operate on a child object for lifetime management:
virDomainSnapshotDelete             virDomainCheckpointDelete
virDomainSnapshotFree               virDomainCheckpointFree
virDomainSnapshotRef                virDomainCheckpointRef

Operate on a child object to learn more about it:
virDomainSnapshotGetXMLDesc         virDomainCheckpointGetXMLDesc
virDomainSnapshotGetConnect         virDomainCheckpointGetConnect
virDomainSnapshotGetDomain          virDomainCheckpointGetDomain
virDomainSnapshotGetName            virDomainCheckpiontGetName
virDomainSnapshotGetParent          virDomainCheckpiontGetParent
virDomainSnapshotHasMetadata        (deferred for later)
virDomainSnapshotIsCurrent          (no counterpart, see note above)

Operate on a domain object to list all children:
virDomainSnapshotNum                (no counterparts, these are the old
virDomainSnapshotListNames           racy interfaces)
virDomainSnapshotListAllSnapshots   virDomainListAllCheckpoints

Operate on a child object to list descendents:
virDomainSnapshotNumChildren        (no counterparts, these are the old
virDomainSnapshotListChildrenNames   racy interfaces)
virDomainSnapshotListAllChildren    virDomainCheckpointListAllChildren

Operate on a domain to locate a particular child:
virDomainSnapshotLookupByName       virDomainCheckpointLookupByName
virDomainSnapshotCurrent            (no counterpart, see note above)
virDomainHasCurrentSnapshot         (no counterpart, old racy interface)

Operate on a snapshot to roll back to earlier state:
virDomainSnapshotRevert             (no counterpart, instead checkpoints
                                     are used in incremental backups via
				     XML to virDomainBackupBegin)

d85842cfd7 backup: Document new XML for checkpoints
Prepare for new checkpoint APIs by describing the XML that will
represent a checkpoint.  The checkpoint XML is modeled heavily after
virDomainSnapshotPtr. See the docs for more details.

Add testsuite coverage for some minimal uses of the XML (bare minimum,
the sample from html, and a full dumpxml, and some counter-examples
that should fail schema validation). Although use of the REDEFINE flag
will require the <domain> subelement to be present, it is easier for
most of the tests to provide counterpart output produced with the
NO_DOMAIN flag (particularly since synthesizing a valid <domain>
during testing is not trivial).

5a148ce846 remote: delete the avahi mDNS support
Libvirtd has long had integration with avahi for advertising libvirtd
using mDNS when TCP/TLS listening is enabled. For a long time the
virt-manager application had support for auto-detecting libvirtds
on the local network using mDNS, but this was removed last year

  commit fc8f8d5d7e3ba80a0771df19cf20e84a05ed2422
  Author: Cole Robinson <crobinso@redhat.com>
  Date:   Sat Oct 6 20:55:31 2018 -0400

    connect: Drop avahi support

    Libvirtd can advertise itself over avahi. The feature is disabled by
    default though and in practice I hear of no one actually using it
    and frankly I don't think it's all that useful

    The 'Open Connection' wizard has a disproportionate amount of code
    devoted to this feature, but I don't think it's useful or worth
    maintaining, so let's drop it

I've never heard of any other applications having support for using
mDNS to detect libvirtd instances. Though it is theoretically possible
something exists out there, it is clearly going to be a niche use case
in the virt ecosystem as a whole.

By removing avahi integration we can cut down the dependency chain for
the basic libvirtd install and reduce our code maint burden.

cdd362e0e7 storage: escape ipv6 for ceph mon hosts to librados
Hosts for rbd are ceph monitor daemons. These have fixed IP addresses,
so they are often referenced by IP rather than hostname for
convenience, or to avoid relying on DNS. Using IPv4 addresses as the
host name works already, but IPv6 addresses require rbd-specific
escaping because the colon is used as an option separator in the
string passed to librados.

Escape these colons, and enclose the IPv6 address in square brackets
so it is distinguished from the port, which is currently mandatory.

6394cf9768 network: convert hook script to take a network port XML
When (un)plugging an interface into a network, the 'plugged'
and 'unplugged' operations are invoked in the hook script.

The data provided to the script contains the network XML, the
domain XML and the domain interface XML. When we strictly split the
drivers up this will no longer be possible and thus breakage is
unavoidable. The hook scripts are not considered to be covered by the
API guarantee so this is OK.

To avoid existing scripts taking the wrong action, the existing
operations are changed to 'port-created' and 'port-deleted'
instead. These will receive the network XML and the network port
XML.

18006c696d gitdm: Add gitdm configuration
This configuration can be used by gitdm to generate reports about
libvirt development.

The goal I was working with was being able to generate a report
for every single libvirt release and having zero "email address
as company" entries; picking different commit ranges might result
in some contributions not being accounted for.

I had to make some judgement calls when the situation was not
entirely clear-cut: when in doubt, and not finding any obvious
signs of the opposite being true, I mostly ended up dumping
people in the "unaffiliated contributions" bin. If I got it
wrong, and companies want to get recognition for their sponsored
contributions to libvirt, they can send patches.

So close to $(docdir)! Including the version number in
the path, specifically, seems entirely unnecessary since
different releases of libvirt are not going to be able to

a007fcab3b snapshot: Don't expose testsuite-only state in snapshot XML
None of the existing drivers actually use the 0-valued 'nostate'
snapshot state; rather, it was a fluke of implementation. In fact,
some drivers, like qemu, actively reject 'nostate' as invalid during a
snapshot redefine. Normally, a driver computes the state post-parse
from the current domain, and thus virDomainSnapshotGetXMLDesc() will
never expose the state. However, since the testsuite lacks any
associated domain to copy state from, and lacks post-parse processing
that normal drivers have, the testsuite output had several spots with
the state, coupled with a regex filter to ignore the oddity.

It is better to follow the lead of other XML defaults, by not
outputting anything during format if post-parse defaults have not been
applied, and rejecting the default value during parsing. The testsuite
needs a bit of an update, by adding another flag for when to simulate
a post-parse action of setting a snapshot state, but none of the
drivers are impacted other than rejecting XML that was previously
already suspicious in nature.

Similarly, don't expose creation time 0 (for now, only possible if a
user redefined a snapshot to claim creation at the Epoch, but also
happens once setting the creation time is deferred to a post-parse
handler).

This is also a step towards cleaning up snapshot_conf.c to separate
its existing post-parse work (namely, setting the creationTime and
default snapshot name) from the pure parsing work, so that we can get
rid of the testsuite hack of regex filtering of the XML and instead
have more accurate testing of our parser/formatter code.

5b9819eedc domain capabilities: Expose firmware auto selection feature
If a management application wants to use firmware auto selection
feature it can't currently know if the libvirtd it's talking to
support is or not. Moreover, it doesn't know which values that
are accepted for the @firmware attribute of <os/> when parsing
will allow successful start of the domain later, i.e. if the mgmt
application wants to use 'bios' whether there exists a FW
descriptor in the system that describes bios.

This commit then adds 'firmware' enum to <os/> element in
<domainCapabilities/> XML like this:

  <enum name='firmware'>
    <value>bios</value>
    <value>efi</value>
  </enum>

We can see both 'bios' and 'efi' listed which means that there
are descriptors for both found in the system (matched with the
machine type and architecture reported in the domain capabilities
earlier and not shown here).
