Split the bit acinclude.m4 file into smaller pieces named
as m4/virt-XXXXX.m4
* .gitignore: Ignore gettext related files
* acinclude.m4: Delete
* m4/virt-compile-warnings.m4: Checks for GCC compiler flags
* m4/virt-pkgconfig-back-compat.m4: Backcompat check for
pkgconfig program
Remove custom code for checking compiler warnings, using
gl_WARN_ADD instead. Don't list all flags ourselves, use
gnulib's gl_MANYWARN_ALL_GCC to get all possible GCC flags,
then turn off the ones we don't want yet.
* acinclude.m4: Rewrite to use gl_WARN_ADD and gl_MANYWARN_ALL_GCC
* bootstrap.conf: Add warnings & manywarnings
* configure.ac: Switch to gl_WARN_ADD
* m4/compiler-flags.m4: Obsoleted by gl_WARN_ADD
Replace openvz_readline with getline in several places to get rid of stack
allocated buffers to hold lines.
openvzReadConfigParam allocates memory for return values instead of
expecting a preexisting buffer.
This patch enables the relative backing file path support provided by
qemu-img create.
If a relative path is specified for the backing file, it is converted
to an absolute path using the storage pool path. The absolute path is
used to verify that the backing file exists. If the backing file exists,
the relative path is allowed and will be provided to qemu-img create.
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.]

If strdup("x509dname") or strdup("saslUsername") success, but
strdup(x509dname) or strdup(saslUsername) failed, subject->nidentity
is not the num elements of subject->identities, and we will leak some
memory.
When you happen to have a libvirtd binary compiled with the
libxenlight driver (say you have installed xen-4.1 libraries)
but not running a xen enabled system, then libvirtd fails to start.
The cause is that libxlStartup() returns -1 when failing to initialize
the library, and this propagates to virStateInitialize() which consider
this a failure. We should only exit libxlStartup with an error code
if something like an allocation error occurs, not if the driver failed
to initialize.
* src/libxl/libxl_driver.c: fix libxlStartup() to not return -1
when failing to initialize the libxenlight library
Commit 78ba748ef1 claims to fix
documentation for swap_hard_limit virsh memtune option but it only fixes
documentation in formatdomain.html and libvirt.h. This patch completes
the task by fixing "virsh help memtune" output and memtune section of
virsh man page.
qemu driver uses a 4K buffer for reading qemu log file. This is enough
when only qemu's output is present in the log file. However, when
debugging messages are turned on, intermediate libvirt process fills the
log with a bunch of debugging messages before it executes qemu binary.
In such a case the buffer may become too small. However, we are not
really interested in libvirt messages so they can be filtered out from
the buffer.
It throws errors as long as the cgroup controller is not available,
regardless of whether we really want to use it to do setup or not,
which is not what we want, fixing it with throwing error when need
to use the controller.
And change "VIR_WARN" to "qemuReportError" for memory controller
incidentally.
We create a temporary file to save memory, and we will remove it after reading
memory to buffer. But we free the variable that contains the temporary filename
before we remove it. So we should free tmp after unlinking it.
The iohelper binary is not required on Win32, although it compiles
without trouble. Simply remove it from the RPM.
* mingw32-libvirt.spec.in: Remove iohelper
printf on Win32 does not necessarily support %lld and we don't
have GNULIBs wrapper for printf(). Switch to use asprintf() for
which we do have a gnulib wrapper with %lld support
* examples/domain-events/events-c/event-test.c: Fix formatting
of %lld on Win32
* cfg.mk: Don't require use of virAsprintf since this is an
example app for out of tree users to follow
strcase{cmp/str} have the drawback of being sensitive to the global
locale; this is unacceptable in a library setting. Prefer a
hard-coded C locale alternative for all but virsh, which is user
facing and where the global locale isn't changing externally.
* .gnulib: Update to latest, for c-strcasestr change.
* bootstrap.conf (gnulib_modules): Drop strcasestr, add c-strcase
and c-strcasestr.
* cfg.mk (sc_avoid_strcase): New rule.
(exclude_file_name_regexp--sc_avoid_strcase): New exception.

(STRCASENEQLEN): Adjust offenders.

Likewise.

If qemu quited unexpectedly when we call qemuMonitorJSONHMP(),
libvirt will crash.
Steps to reproduce this bug:
1. use gdb to attach libvirtd, and set a breakpoint in the function
qemuMonitorSetCapabilities()
2. start a vm
3. let the libvirtd to run until qemuMonitorJSONSetCapabilities() returns.
4. kill the qemu process
5. continue running libvirtd

If the monitor met a error, and we will call qemuProcessHandleMonitorEOF().
But we may try to send monitor command after qemuProcessHandleMonitorEOF()
returned. Then libvirtd will be blocked in qemuMonitorSend().
Steps to reproduce this bug:
1. use gdb to attach libvirtd, and set a breakpoint in the function
qemuConnectMonitor()
2. start a vm
3. let the libvirtd to run until qemuMonitorOpen() returns.
4. kill the qemu process
5. continue running libvirtd

Currently libvirt's default logging is limited and it is difficult to
determine what was happening when a proglem occurred (especially on a
machines where one don't know the detail.) This patch helps to do that
by making additional logging available for the following events:
creating/defining/undefining domains
creating/defining/undefining/starting/stopping networks
creating/defining/undefining/starting/stopping storage pools
creating/defining/undefining/starting/stopping storage volumes.
* AUTHORS: add Naoya Horiguchi
* src/network/bridge_driver.c src/qemu/qemu_driver.c
src/storage/storage_driver.c: provide more VIR_INFO logging
