088473b29f build: avoid ATTRIBUTE_UNUSED in headers
The compiler might optimize based on our declaration that something
is unused.  Putting that declaration in the header risks getting
out of sync with the actual implementation, so it belongs better
only in the .c files.  We were mostly compliant, and a new syntax
check will help us in the future.

* cfg.mk (sc_avoid_attribute_unused_in_header): New syntax check.
* src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Delete
attribute already present in .c file.
* src/qemu/qemu_domain.h (qemuDomainEventFlush): Likewise.
* src/util/virterror_internal.h (virReportErrorHelper): Parameters
are actually used by .c file.
* src/xenxs/xen_sxpr.h (xenFormatSxprDisk): Adjust prototype.
* src/xenxs/xen_sxpr.c (xenFormatSxprDisk): Delete unused argument.
(xenFormatSxpr): Adjust caller.
* src/xen/xend_internal.c (xenDaemonAttachDeviceFlags)
(xenDaemonUpdateDeviceFlags): Likewise.
Suggested by Daniel Veillard.

833fe8abec util: reject unknown flags, and prefer unsigned flags
Silently ignored flags get in the way of new features that
use those flags.  Also, an upcoming syntax check will favor
unsigned flags.

* src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Drop
unused attribute.
* src/interface/netcf_driver.c (interfaceOpenInterface)
(interfaceDefineXML, interfaceCreate, interfaceDestroy): Reject
unknown flags.
* src/network/bridge_driver.c (networkOpenNetwork)
(networkGetXMLDesc): Likewise.
* src/nwfilter/nwfilter_driver.c (nwfilterOpen): Likewise.
* src/secret/secret_driver.c (secretOpen, secretDefineXML)
(secretGetXMLDesc, secretSetValue): Likewise.
* src/util/logging.c (virLogDefineFilter, virLogDefineOutput)
(virLogMessage): Likewise; also use unsigned flags.
* src/util/logging.h (virLogDefineFilter, virLogDefineOutput)
(virLogMessage): Change signature.
* src/util/command.c (virExecWithHook): Likewise.

b0b968efd5 Generic shared impls of all NUMA apis 2009-06-03 13:28:02 +00:00
Jim Meyering
d010b68962 make NUMA-initialization code more portable and more robust
qemudCapsInitNUMA and umlCapsInitNUMA were identical, so this change
factors them into a new function, virCapsInitNUMA, and puts it in
nodeinfo.c.

In addition to factoring out the duplicates, this change also
adjusts that function definition (along with its macros) so
that it works with Fedora 9's numactl version 1, and makes it
so the code will work even if someone builds the kernel with
CONFIG_NR_CPUS > 4096.

Finally, also perform this NUMA initialization for the lxc
and openvz drivers.

* src/nodeinfo.c: Include <stdint.h>, <numa.h> and "memory.h".
(virCapsInitNUMA): Rename from qemudCapsInitNUMA and umlCapsInitNUMA.
(NUMA_MAX_N_CPUS): Define depending on NUMA API version.
(n_bits, MASK_CPU_ISSET): Define, adjust, use uint64 rather than long.
* src/nodeinfo.h: Include "capabilities.h".
(virCapsInitNUMA): Declare it.
* examples/domain-events/events-c/Makefile.am:
* src/Makefile.am: Add $(NUMACTL_CFLAGS) and $(NUMACTL_LIBS) to various
compile/link-related variables.
* src/qemu_conf.c: Include "nodeinfo.h".
(qemudCapsInitNUMA): Remove duplicate code.  Adjust caller.
* src/uml_conf.c (umlCapsInitNUMA): Likewise.
Include "nodeinfo.h".
* src/lxc_conf.c: Include "nodeinfo.h".
(lxcCapsInit): Perform NUMA initialization here, too.
* src/openvz_conf.c (openvzCapsInit): And here.
Include "nodeinfo.h".
* src/libvirt_sym.version.in: Add virCapsInitNUMA so that libvirtd
can link to this function.

3da5504e68 Fix gcc-4.3.0 "inlining failed" warning.
* src/internal.h: move xstrol() variants from here ...

* src/util.[ch]: ... to here and rename to virStrToLong()

* src/libvirt_sym.version: export __virStrToLong_i() for
virsh and qemud.

* src/nodeinfo.c, src/stats_linux.c, src/virsh.c,
  src/xend_internal.c, qemud/qemud.c: replace xstrtol()
calls with virStrToLong()

* src/nodeinfo.h: don't include internal.h, which was only
needed for xstrtol(), but instead include libvirt.h which
is suffificient for the declarations in the header.
