The network filter / snapshot / hooks code introduced some
non-portable pices that broke the win32 build
* configure.ac: Check for net/ethernet.h required by nwfile config
parsing code
* src/conf/nwfilter_conf.c: Define ethernet protocol constants
if net/ethernet.h is missing
* src/util/hooks.c: Disable hooks build on Win32 since it lacks
fork/exec/pipe
* src/util/threads-win32.c: Fix unchecked return value
* tools/virsh.c: Disable SIGPIPE on Win32 since it doesn't exist.
Fix non-portable strftime() formats
Document several missing commands. There's more work that could be
done, but incremental improvements is better than no patch at all.
* tools/virsh.pod (autostart, connect): Improve grammar.
(create): Improve example.
(domjobabort, domjobinfo, domxml-from-native, domxml-to-native):
Document.
(storage pool commands): New section.
When hitting failures in virsh, a common idiom is
to jump to a cleanup label, free some resources, and
then return a FALSE error code to vshCommandRun.
In theory, vshCommandRun is then supposed to print
out the last error. The problem is that many of
the cleanup paths have library calls to free resources,
and all of those library calls clear out the last error.
This is leading to situations where no error is being
reported at all.
This patch remedies the situation somewhat by
printing out the errors inside the command methods
themselves when we know it will go through a cleanup
path that will lose the error.

A lot of syntax check rules have to be rewritten, but the
result is easier to maintain. I tested each syntax rule
by intentionally introducing a temporary violation of the rule.
Additionally, some false positives for unmarked_diagnostics
crept in, and an improved copyright_format test caught some bugs.
* .gnulib: Update to latest.
* cfg.mk (sc_prohibit_test_minus_ao): Delete, it was moved into
gnulib's maint.mk.
(sc_avoid_write, sc_prohibit_strcmp_and_strncmp)
(sc_prohibit_asprintf, sc_prohibit_strncpy, sc_prohibit_readlink)
(sc_prohibit_gethostname, sc_prohibit_gettext_noop)
(sc_prohibit_VIR_ERR_NO_MEMORY, sc_prohibit_nonreentrant)
(sc_prohibit_ctype_h, sc_TAB_in_indentation)
(sc_avoid_ctype_macros)
(sc_prohibit_virBufferAdd_with_string_literal)
(sc_prohibit_gethostby, sc_copyright_format): Rewrite in terms of
new maint.mk macros.
(sc_libvirt_unmarked_diagnostics): Fix whitespace.
* .x-sc_unmarked_diagnostics: New file.
* tests/object-locking.ml: Fix copyright.
* tools/virt-pki-validate.in: Likewise.
* tools/virt-xml-validate.in: Likewise.
* cfg.mk (sc_prohibit_test_minus_ao): Also check for [.
* docs/Makefile.am (%.html, html/index.html): Avoid non-portable
test usage.
* libvirt.spec.in (%post): Likewise.
* tools/virt-pki-validate.in (servercert.pem): Likewise.
* configure.ac (LOGNAME): Use test, not [, in files processed by
autoconf.

Call me lazy: some shells use exit (e.g. sh), others use quit (e.g. ftp),
but I never remember which. So it's faster to write a patch to make
virsh take both than it is to take a 50-50 guess, and get it wrong
in half of my attempts.
* tools/virsh.c (commands): Add 'exit'.
* tools/virsh.pod: Document it.
Common Unix practice is to prefer VISUAL over EDITOR, particularly if
the editor of choice spawns a new window. Thus, it is also common to
see settings like EDITOR='emacs -nw', with the expectation that the
shell will parse this as an argument to 'emacs' and not try to invoke
a file containing a space.
If a user puts junk in EDITOR, they deserve what they get (much more
than virsh will misbehave); furthermore, sudo scrubs EDITOR by
default. So the blind use of metacharacters in EDITOR should not be
considered too much of a security issue.
* tools/virsh.c (editFile): Prefer VISUAL over EDITOR. Don't
reject shell metacharacters in EDITOR.
* tools/virsh.pod (edit, net-edit, ENVIRONMENT): Document VISUAL.

This flag is used in migration prepare step to send updated XML
definition of a guest.
Also ``virsh dumpxml --update-cpu [--inactive] guest'' command can be
used to see the updated CPU requirements.
Support the new virDomainUpdateDeviceFlags API in virsh by adding
a new 'update-device' command. In the future this should be augmented
with an explicit 'change-disk' command for media change to make it
end user discoverable, as attach-disk is.
* tools/virsh.c: Add 'update-device' command
If you ran virsh in interactive mode and ran a command
that virsh could not parse, it would then SEGV
on subsequent commands. The problem is that we are
freeing the vshCmd structure in the syntaxError label
at the end of vshCommandParse, but forgetting to
set ctl->cmd to NULL. This means that on the next command,
we would try to free the same structure again, leading
to badness.
* tools/virsh.c: Make sure to set ctl->cmd to NULL after
freeing it in vshCommandParse()
No functional change. These all generated compiler warnings which, for
some reason weren't converted to errors by
--enable-compiler-warnings=error.
* tools/virsh.c:
- change return type from int to void on two functions that don't
return a value.
- remove unused variables/labels from two functions
- eliminate non-literal format strings
- typecast char* into xmlChar* when calling
- xmlParseBalancedChunkMemory
When the daemon libvirtd restarts, a connected virsh gets a SIGPIPE
and dies. This change the behaviour to try to reconnect if the
signal was received or command error indicated a connection or RPC
failure. Note that the failing command is not restarted.
* tools/virsh.c: catch SIGPIPE signals as well as connection related
failures, add some automatic reconnection code and appropriate error
messages.
With N_() in place, we can use it for a smaller file.
* doc/api-extension/0008-Step-8-of-8-Add-virsh-support.patch:
Replace all uses of gettext_noop with N_.
* tools/virsh.c: Likewise, throughout the file.
It is a bad idea to call gettext on an already-translated
string. In cases where a string must be translated separately
from where it is exposed to xgettext, the gettext manual
recommends the idiom of N_() wrapping gettext_noop for
marking the string.
* src/internal.h (N_): Fix definition to match gettext manual.
* tools/virsh.c: (cmdHelp, cmdList, cmdDomstate, cmdDominfo)
(cmdVcpuinfo, vshUsage): Replace incorrect use of N_ with _.
(vshCmddefHelp): Likewise. Mark C format strings appropriately.
This supports cancellation of jobs for the QEMU driver against
the virDomainMigrate, virDomainSave and virDomainCoreDump APIs.
It is not yet supported for the virDomainRestore API, although
it is desirable.
* src/qemu/qemu_driver.c: Issue 'migrate_cancel' command if
virDomainAbortJob is issued during a migration operation
* tools/virsh.c: Add a domjobabort command
Introduce support for virDomainGetJobInfo in the QEMU driver. This
allows for monitoring of any API that uses the 'info migrate' monitor
command. ie virDomainMigrate, virDomainSave and virDomainCoreDump
Unfortunately QEMU does not provide a way to monitor incoming migration
so we can't wire up virDomainRestore yet.
The virsh tool gets a new command 'domjobinfo' to query status
* src/qemu/qemu_driver.c: Record virDomainJobInfo and start time
in qemuDomainObjPrivatePtr objects. Add generic shared handler
for calling 'info migrate' with all migration based APIs.
* src/qemu/qemu_monitor_text.c: Fix parsing of 'info migration' reply
* tools/virsh.c: add new 'domjobinfo' command to query progress
* tools/virsh.c (cmdPoolDiscoverSources): Always initialize srcSpec.
Otherwise, clang would report that srcSpec could be used uninitialized
in the call to virConnectFindStoragePoolSources.
Only API calls trigger the error callback, which is required for
proper virsh error reporting. Since we use non API functions from
util/, make sure we properly report these errors.
Fixes lack of error message from 'virsh create idontexit.xml'
There is no real leak here, but Coverity-Prevent thinks there is.
It does not see that while there are four ways to return from
vshCommandGetToken with VSH_TK_END, none of them results in allocation
of a result.
* tools/virsh.c (vshCommandParse): Add a (currently) useless VIR_FREE,
to ensure that we never leak when vshCommandGetToken returns VSH_TK_END.
Change all virsh commands that invoke virDomain{Attach,Detach}Device()
to use virDomain{Attach,Detach}DeviceFlags() instead.
Add a "--persistent" flag to these virsh commands, allowing user to
specify that the domain persisted config be modified as well.
V2: Only invoke virDomain{Attach,Detach}DeviceFlags() if
"--persistent" flag is specified. Otherwise invoke
virDomain{Attach,Detach}Device() to retain current behavior.
I noticed some debug messages are printed with an empty lines after
them. This patch removes these empty lines from all invocations of the
following macros:
VIR_DEBUG
VIR_DEBUG0
VIR_ERROR
VIR_ERROR0
VIR_INFO
VIR_WARN
VIR_WARN0
