      Initialize couple of variables. · bde6e002
      由 Michal Privoznik 提交于 
      While trying to build with -Os couple of compile errors showed
up.

conf/domain_conf.c: In function 'virDomainChrRemove':
conf/domain_conf.c:13666:24: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     virDomainChrDefPtr ret, **arrPtr = NULL;
                        ^
Compiler fails to see that @ret is used only if set in the loop,
but whatever, there's no harm in initializing the variable.

In vboxAttachDrivesNew and _vboxAttachDrivesOld compiler thinks
that @rc may be used uninitialized. Well, not directly, but maybe
after some optimization. Yet again, no harm in initializing a
variable.

In file included from ./util/virthread.h:26:0,
                 from ./datatypes.h:28,
                 from vbox/vbox_tmpl.c:43,
                 from vbox/vbox_V3_1.c:37:
vbox/vbox_tmpl.c: In function '_vboxAttachDrivesOld':
./util/virerror.h:181:5: error: 'rc' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     virReportErrorHelper(VIR_FROM_THIS, code, __FILE__,              \
     ^
In file included from vbox/vbox_V3_1.c:37:0:
vbox/vbox_tmpl.c:1041:14: note: 'rc' was declared here
     nsresult rc;
              ^
Yet again, one uninitialized variable:

qemu/qemu_driver.c: In function 'qemuDomainBlockCommit':
qemu/qemu_driver.c:17194:9: error: 'baseSource' may be used uninitialized in this function [-Werror=maybe-uninitialized]
         qemuDomainPrepareDiskChainElement(driver, vm, baseSource,
         ^

And another one:

storage/storage_backend_logical.c: In function 'virStorageBackendLogicalMatchPoolSource.isra.2':
storage/storage_backend_logical.c:618:33: error: 'thisSource' may be used uninitialized in this function [-Werror=maybe-uninitialized]
                       thisSource->devices[j].path))
                                 ^

      Drop inline keyword from some functions. · be8b536a
      由 Michal Privoznik 提交于 
      While trying to build with -Os I've encountered some build
failures.

util/vircommand.c: In function 'virCommandAddEnvFormat':
util/vircommand.c:1257:1: error: inlining failed in call to 'virCommandAddEnv': call is unlikely and code size would grow [-Werror=inline]
 virCommandAddEnv(virCommandPtr cmd, char *env)
 ^
util/vircommand.c:1308:5: error: called from here [-Werror=inline]
     virCommandAddEnv(cmd, env);
     ^
This function is big enough for the compiler to be not inlined.
This is the error message I'm seeing:

Then virDomainNumatuneNodeSpecified is exported and called from
other places. It shouldn't be inlined then.

In file included from network/bridge_driver_platform.h:30:0,
                 from network/bridge_driver_platform.c:26:
network/bridge_driver_linux.c: In function 'networkRemoveRoutingFirewallRules':

      daemon: fixup refcounting in close callback handling · ce35122c
      由 Nikolay Shirokovskiy 提交于 
      remoteDispatchConnectCloseCallbackRegister introduced in
f484310a has problems. It refcounts network client object and in case of NOOP
driver operations for registering/unregistering close callback (any driver
except for vz) nobody will unref it later. As a result, client connection
will not be disposed and driver connection will not be closed.

The fix is easy. We don't need to refcount at all. We don't get a dangling
pointer because in remoteClientFreeFunc, which is called
upon disposing this network client object, we unregister the close
callback.

      由 John Ferlan 提交于 
      More fallout from changing to using virPolkitAgent and handling error
paths.  Needed to clear the 'cmd' once stored and of course add the
virCommandFree(cmd) in the error: label.

      datatypes.c: Replace 'close' with 'closeData' · f5f1ccbc
      由 Michal Privoznik 提交于 
      Older compilers fail to see that 'close' is not used a function
rather than a variable and produce the following error:

cc1: warnings being treated as errors
../../src/datatypes.c: In function 'virConnectCloseCallbackDataReset':
../../src/datatypes.c:149: error: declaration of 'close' shadows a global declaration [-Wshadow]

Replace all the 'close' occurrences with 'closeData' to resolve
this.

      In virPolkitAgentCreate neglected to initialize agent to NULL. If
there was an error in the pipe, then we jump to error and would have
an issue. Found by coverity.

      Libvirt: Add missing default value for config option max_queued_clients · b3a4b176
      由 Jason J. Herne 提交于 
      Commit 1199edb1 added config option max_queued_clients and documented the
default value as 1000 but never actually set that value. This patch sets the
default value.

This addresses an issue whereby the following error message is reported if too
many migrations are started simultaneously:

error: End of file while reading data: Ncat: Invalid argument.: Input/output error

The problem is that too many ncat processes are spawned on the destination
system. They all attempt to connect to the libvirt socket. Because the
destination libvirtd cannot respond to the connect requests quickly enough we
overrun the socket's pending connections queue.
