9583b0b7e3 libvirt-qemu: Don't allow NULL cmd in virDomainQemuMonitorCommandWithFiles()
Nothing in daemon code is prepared for the command in
virDomainQemuMonitorCommandWithFiles() to be NULL. In fact, the
client side doesn't expect this either as our RPC describes the
argument as:

    remote_nonnull_string cmd;

Validate the argument in the public API implementation.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

32d6c7386d Print hex values with '0x' prefix and octal with '0' in debug messages
Seeing a log message saying 'flags=93' is ambiguous & confusing unless
you happen to know that libvirt always prints flags as hex.  Change our
debug messages so that they always add a '0x' prefix when printing flags,
and '0' prefix when printing mode. A few other misc places gain a '0x'
prefix in error messages too.

43b17dd444 qemu: allow filtering events by regex
When listening for a subset of monitor events, it can be tedious
to register for each event name in series; nicer is to register
for multiple events in one go.  Implement a flag to use regex
interpretation of the event filter.

While at it, prove how much I hate the shift key, by adding a
way to filter for 'shutdown' instead of 'SHUTDOWN'. :)

2629520342 qemu: new API for tracking arbitrary monitor events
Several times in the past, qemu has implemented a new event,
but libvirt has not yet caught up to reporting that event to
the user applications.  While it is possible to track libvirt
logs to see that an unknown event was received and ignored,
it would be nicer to copy what 'virsh qemu-monitor-command'
does, and expose this information to the end developer as
one of our unsupported qemu-specific commands.

If you find yourself needing to use this API for more than
just development purposes, please ask on the libvirt list
for a supported counterpart event to be added in libvirt.so.

While the supported virConnectDomainEventRegisterAny() API
takes an id which determines the signature of the callback,
this version takes a string filter and always uses the same
signature.  Furthermore, I chose to expose this as a new API
instead of trying to add a new eventID at the top level, in
part because the generic option lacks event name filtering,
and in part because the normal domain event namespace should
not be polluted by a qemu-only event.  I also added a flags
argument; unused for now, but we might decide to use it to
allow a user to request event names by glob or regex instead
of literal match.

This API intentionally requires full write access (while
normal event registration is allowed on read-only clients);
this is in part due to the fact that it should only be used
by debugging situations, and in part because the design of
per-event filtering in later patches ended up allowing for
duplicate registrations that could potentially be abused to
exhaust server memory - requiring write privileges means
that such abuse will not serve as a denial of service attack
against users with higher privileges.

6e130ddc4d maint: improve VIR_ERR_INVALID_DOMAIN usage
In datatype.c, virGetDomainSnapshot could result in the message:

error: invalid domain pointer in bad domain

Furthermore, while there are a few functions in libvirt.c that
only care about a virDomainPtr without regards to the connection
(such as virDomainGetName), most functions also require a valid
connection.  Yet several functions were blindly dereferencing
the conn member without checking it for validity first (such as
virDomainOpenConsole).  Rather than try and correct all usage
of VIR_IS_DOMAIN vs. VIR_IS_CONNECTED_DOMAIN, it is easier to
just blindly require that a valid domain object always has a
valid connection object (which should be true anyways, since
every domain object holds a reference to its connection, so the
connection will not be closed until all domain objects have
also been closed to release their reference).

After this patch, all places that validate a domain consistently
report:

error: invalid domain pointer in someFunc

macros.
* src/datatypes.c (virGetDomainSnapshot): Use new macro.

db3dd0824f maint: improve VIR_ERR_INVALID_CONN usage
The datatype.c object checks could result in a message like:

error: invalid connection pointer in no connection

This consolidates all clients of this message to have uniform contents:

error: invalid connection pointer in someFunc

Note that virCheckConnectReturn raises an error immediately; in
datatypes.c, where we don't need to raise the error (but instead
just leave it in the thread-local setting), we use
virCheckConnectGoto and the cleanup label instead.  Then, for
consistency in that file, all subsequent error messages are
touched to also use the cleanup error label.

d219826c65 maint: improve VIR_ERR_OPERATION_DENIED usage
Some of our operation denied messages are outright stupid; for
example, if virIdentitySetAttr fails:

error: operation Identity attribute is already set forbidden for read only access

This patch fixes things to a saner:

error: operation forbidden: Identity attribute is already set

It also consolidates the most common usage pattern for operation
denied errors: read-only connections preventing a public API.  In
this case, 'virsh -r -c test:///default destroy test' changes from:

error: operation virDomainDestroy forbidden for read only access

to:

error: operation forbidden: read only access prevents virDomainDestroy

Note that we were previously inconsistent on which APIs used
VIR_FROM_DOM (such as virDomainDestroy) vs. VIR_FROM_NONE (such as
virDomainPMSuspendForDuration).  After this patch, all uses
consistently use VIR_FROM_NONE, on the grounds that it is unlikely
that a caller learning that a call is denied can do anything in
particular with extra knowledge which error domain the call belongs
to (similar to what we did in commit baa7244).

baa7244951 maint: improve VIR_ERR_NO_SUPPORT usage
We weren't very consistent in our use of VIR_ERR_NO_SUPPORT; many
users just passed __FUNCTION__ on, while others passed "%s" to
silence over-eager compilers that warn about __FUNCTION__ not
containing any %.  It's nicer to route all these uses through
a single macro, so that if we ever need to change the reporting,
we can do it in one place.

I verified that 'virsh -c test:///default qemu-monitor-command test foo'
gives the same error message before and after this patch:
error: this function is not supported by the connection driver: virDomainQemuMonitorCommand

Note that in libvirt.c, we were inconsistent on whether virDomain*
API used virLibConnError() (with VIR_FROM_NONE) or virLibDomainError()
(with VIR_FROM_DOMAIN); this patch unifies these errors to all use
VIR_FROM_NONE, on the grounds that it is unlikely that a caller
learning that a call is unimplemented can do anything in particular
with extra knowledge of which error domain it belongs to.

One particular change to note is virDomainOpenGraphics which was
trying to fail with VIR_ERR_NO_SUPPORT after a failed
VIR_DRV_SUPPORTS_FEATURE check; all other places that fail a
feature check report VIR_ERR_ARGUMENT_UNSUPPORTED.

f06d55da7b maint: reset error on entrance to public API

libvirt errors in the same thread; but weren't obeying this

There are a couple of nested uses of virConnectRef (in lxc

3e2c3d8f6d build: use correct type for pid and similar types
No thanks to 64-bit windows, with 64-bit pid_t, we have to avoid
constructs like 'int pid'.  Our API in libvirt-qemu cannot be
changed without breaking ABI; but then again, libvirt-qemu can
only be used on systems that support UNIX sockets, which rules
out Windows (even if qemu could be compiled there) - so for all
points on the call chain that interact with this API decision,
we require a different variable name to make it clear that we
audited the use for safety.

Adding a syntax-check rule only solves half the battle; anywhere
that uses printf on a pid_t still needs to be converted, but that
will be a separate patch.

21adf03c2d Qemu Monitor API entry point.
Add the library entry point for the new virDomainQemuMonitorCommand()
entry point.  Because this is not part of the "normal" libvirt API,
it gets its own header file, library file, and will eventually
get its own over-the-wire protocol later in the series.

Changes since v1:
 - Go back to using the virDriver table for qemuDomainMonitorCommand, due to
   linking issues
 - Added versioning information to the libvirt-qemu.so

Changes since v2:
 - None

Changes since v3:
 - Add LGPL header to libvirt-qemu.c
 - Make virLibConnError and virLibDomainError macros instead of function calls

Changes since v4:
 - Move exported symbols to libvirt_qemu.syms
