The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

The only useful translation of "%s" as a format string is "%s" (I
suppose you could claim "%1$s" is also valid, but why bother). So
it is not worth translating; fixing this exposes some instances
where we were failing to translate real error messages. This makes
the fix of commit 097da1ab more generic, as well as ensuring no
future regressions.

Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.
File changes:
- src/util/viruri.h -- declaration
- src/util/viruri.c -- definition
- src/libvirt_private.syms -- symbol export
- src/Makefile.am -- added source and header files
- cfg.mk -- added sc_prohibit_xmlURI
- all others -- ID name and include fixes
privP->session->error_description is a list and in order to get the
complete error message all parts of the list should be concatenated.
xenapiSessionErrorHandler does this when its third parameter is NULL.
The current code discards all but the first part of the error message
resulting in a potentially incomplete error message.
This partly reverts 006be75ee2, that tried to avoid reporting
a (null) in the error message. The actual problem is more general in
returnErrorFromSession that might return NULL if there is no error.
Make sure that returnErrorFromSession return non-NULL always. Also
don't skip the last error message part.
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose. Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.
global rename performed with:
$ git grep -l virBufferVSprintf \
| xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'
then revert the changes in ChangeLog-old.
Even with -Wuninitialized (which is part of autobuild.sh
--enable-compile-warnings=error), gcc does NOT catch this
use of an uninitialized variable:
{
if (cond)
goto error;
int a = 1;
error:
printf("%d", a);
}
which prints 0 (supposing the stack started life wiped) if
cond was true. Clang will catch it, but we don't use clang
as often. Using gcc -Wjump-misses-init catches it, but also
gives false positives:
{
if (cond)
goto error;
int a = 1;
return a;
error:
return 0;
}
Here, a was never used in the scope of the error block, so
declaring it after goto is technically fine (and clang agrees).
However, given that our HACKING already documents a preference
to C89 decl-before-statement, the false positive warning is
enough of a prod to comply with HACKING.
[Personally, I'd _really_ rather use C99 decl-after-statement
to minimize scope, but until gcc can efficiently and reliably
catch scoping and uninitialized usage bugs, I'll settle with
the compromise of enforcing a coding standard that happens to
reject false positives if it can also detect real bugs.]

xen-unstable c/s 16931 introduced a per-domain setting for hvm
guests to enable/disable hardware assisted paging. If disabled,
software techniques such as shadow page tables are used. If enabled,
and the feature exists in underlying hardware, hardware support for
paging is used.
This provides implementation for mapping HAP setting to/from
domxml/native formats in xen drivers.
Although this patch adds a distinction between maximum vcpus and
current vcpus in the XML, the values should be identical for all
drivers at this point. Only in subsequent per-driver patches will
a distinction be made.
In general, virDomainGetInfo should prefer the current vcpus.

Xen supports on_crash actions coredump-{destroy,restart}. libvirt
cannot parse config returned by xend that contains either of these
actions
xen52 # xm li -l test | grep on_crash
(on_crash coredump-restart)
xen52 # virsh dumpxml test
error: internal error unknown lifecycle type coredump-restart
This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.
