The utils code should stay separated from other code (except for very
well justified cases). Unfortunately commit 272769becc
made it trivial to break the separation (and not get slapped by the
syntax-check rule) by adding -I src/conf to the CFLAGS for utils.
Remove this shortcut and except the two offenders from the syntax check
so that the codebase can be kept separated.
Problem with VIR_FREE() is that we are not linking
libvirt-utils.so to our mock libs therefore there will be an
unresolved symbol. Fortunately, nsstest that eventually links
with the nssmock links also with libvirt-utils.so and thus the
symbol is resolved after all. However, if one wants to run the
test binary under valgrind it is impossible to do so. Because of
the unresolved symbol.

This script can already operate on a list of files.

The prohibit_nonreentrant syntax-check rule spawns a new shell

Since the line with the offending function is already printed

Fix the regex for excluding files for this syntax-rule. The rule "include/"

There is a lot to explain, but I try to make it as short as
possible. I'd start by pasting some parts of sys/stat.h:
extern int stat (const char *__restrict __file,
struct stat *__restrict __buf) __THROW __nonnull ((1, 2));
extern int __REDIRECT_NTH (stat, (const char *__restrict __file,
struct stat *__restrict __buf), stat64)
__nonnull ((1, 2));
__extern_inline int
__NTH (stat (const char *__path, struct stat *__statbuf))
{
return __xstat (_STAT_VER, __path, __statbuf);
}
Only one of these is effective at once, due to some usage of
the mess we are dealing with in here. So, basically, while
compiling or linking stat() in our code can be transformed into
some other func. Or a dragon.
Now, if you read stat(2) manpage, esp. "C library/kernel
differences" section, you'll learn that glibc uses some tricks
for older applications to work. I haven't gotten around actual
code that does this, but based on my observations, if 'stat'
symbol is found, glibc assumes it's dealing with ancient
application. Unfortunately, it can be just ours stat coming from
our mock. Therefore, calling stat() from a test will end up in
our mock. But since glibc is not exposing the symbol anymore, our
call of real_stat() will SIGSEGV immediately as the pointer to
function is NULL. Therefore, we should expose only those symbols
we know glibc has.

To prevent the error messages in cfg.mk from triggering the very
same rules they're supposed to explain, we split the message in
the middle of a symbol name, ending up with stuff like
'I am a me'ssage
Instead of relying on these quotation tricks, simply exclude
cfg.mk from the relevant checks.
Being consistent is nice, especially when it comes to defining our
regular expression, where using single quotes instead of double
quotes allows us to leave out a few backslashes.
Changing this required altering a few error messages.
The only remaining use of double quotes is one where they are
actually required for the check to work.

As mock libraries are not to be linked against libvirt, the
sc_prohibit_close syntax-check rule does not apply.
This fixes a syntax-check failure introduced by commit a03cbfe0fb.
There might be cases, like with typed params, where triggering this check isn't
desirable. But including the whole module in the exception regex is not always
to right way of doing things. By adding an option to manually disable this check
on a specific occurrence, the module itself will still be checked against the
rule.
As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.
Currently the QEMU stdout/stderr streams are written directly to
a regular file (eg /var/log/libvirt/qemu/$GUEST.log). While those
can be rotated by logrotate (using copytruncate option) this is
not very efficient. It also leaves open a window of opportunity
for a compromised/broken QEMU to DOS the host filesystem by
writing lots of text to stdout/stderr.
This makes it possible to connect the stdout/stderr file handles
to a pipe that is provided by virtlogd. The virtlogd daemon will
read from this pipe and write data to the log file, performing
file rotation whenever a pre-determined size limit is reached.

tests: handle backspace-newline pairs in test input files
all the test argv files were line wrapped so that the args
were less than 80 characters.
The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.
This commit changes the line wrapping so that every
single "-param value" is one its own new line. If the
"value" is still too long, then we break on ',' or ':'
or ' ' as needed.
This means that when we come to add / remove parameters
from the test files line, the patch diffs will only
ever show a single line added/removed which will greatly
simplify review work.

In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.

Initial scratch of the admin library. It has its own virAdmConnectPtr

There's pkg-config file added and spec-file adjusted as well.
Since the library should be "minimalistic" and not depend on any other

could've been put to it's own sub-libraries that would be LIBADD'd to

In order not to bring in any link dependencies, bridge driver doesn't
use the usual stubs as other conditionally-built code does. However,
having the function as a macro imposes a problem with possibly unused
variables if just defined as "0". This was worked around by using
(dom=dom, iface=iface, 0) which should act like a 0 if used in a
condition. However, gcc still bugs about that, so I came up with
another way how to fix that.
Using static inline functions in the header won't collide with anything,
it fixes the bug and does one thing that the macro didn't do. It checks
whenther passed variables are pointers of compatible type. It has only
one downside, and that is that we need to either a) define it with
ATTRIBUTE_UNUSED, which needs an exception in cfg.mk or b) do something
like ignore_value(variable); in the function body. I went with the
first variant.

Per-cpu stats are only shown for present CPUs in the cgroups,

Introduce a Xen xl parser
This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below
target, format, vdev, access
The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as
devtype, backend, backendtype, script, direct-io-safe,
The positional paramters can also be specified in key/value form
for example
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
are interpleted to one config.
In xm format, the above diskspec would be written as
phy:/dev/vg/guest-volume,hda,w
The disk parser is based on the same parser used successfully by
the Xen project for several years now. Ian Jackson authored the
scanner, which is used by this commit with mimimal changes. Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.
