* src/util/network.c: Adjust comments.
Suggested by Matthias Bolte.
Tested by running 'git submodule foreach git pull origin master' and
'git add .gnulib', then seeing that 'make clean' skips autogen
although 'make' properly runs it.
* cfg.mk (_clean_requested): New check, to speed up 'make clean'
even if gnulib submodule is outdated.
Suggested by Daniel P. Berrange.
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.

Use git diff to expose whether the submodule has untracked changes,
which are typical on an incremental pull if .gnulib was updated but
the user did not manually run 'git submodule update'.
After this patch is applied, I encountered a new problem when
following the reproducing pattern. Basically, the change to .gnulib
between libvirt's commit 96e5a2d4 and this patch introduced a change
to sys_ioctl.in.h, but gnulib (intentionally) does not make the
replacement headers depend on Makefile changes. Therefore, I ended up
with the generated replacement header being broken:
gnulib/lib/sys/ioctl.h complained about a use of @. But that seems
like something that should be fixed upstream in gnulib's bootstrap
script (that is, when doing a gnulib update, all files created from
.in.h file should probably be deleted). Without the benefit of that
proposed gnulib fix, I worked around the problem by manually removing
the stale gnulib/lib/sys/ioctl.h.
* autogen.sh (t): Also run bootstrap if the gnulib submodule needs
to be updated.
* cfg.mk (_autogen): Likewise.
Reported by Matthias Bolte.
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.
Detected by Matthias Bolte.
virStrToLong* guarantees (via strtol) that the end pointer will be set
to the point at which parsing stopped (even on failure, this point is
the start of the input string).
* src/esx/esx_driver.c (esxGetVersion): Remove pointless
conditional.
* src/qemu/qemu_conf.c (qemuParseCommandLinePCI)
(qemuParseCommandLineUSB, qemuParseCommandLineSmp): Likewise.
* src/qemu/qemu_monitor_text.c
(qemuMonitorTextGetMigrationStatus): Likewise.
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.
Automate the reuse of autogen.sh, rather than just erroring out.
* cfg.mk (_update_required): Run autogen.sh, rather than just
warning about it.
(_autogen): New target.
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.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=487738.
My prior patch forced an autogen.sh run, and I was surprised that the
suggested './autogen.sh' lost the fact that I had previously used
'./autogen.sh -C' for speed.
* autogen.sh: Use config.status, if present and there were no arguments.

Picks up fixes for gethostname compilation problems on mingw.
* .gnulib: Update to latest.
* build-aux/.gitignore: Regenerate.
* cfg.mk (local-checks-to-skip): Avoid new test not relevent to
libvirt.
POSIX states that creation of a mutex with default attributes
is unspecified whether the mutex is recursive or non-recursive.
We specifically want non-recursive (deadlock is desirable in
flushing out coding bugs that used our mutex incorrectly).
* src/util/threads-pthread.c (virMutexInit): Specifically request
non-recursive mutex, rather than relying on unspecified default.
* autogen.sh (curr_status): Also include hash of bootstrap.conf
when checking for changes that require bootstrap rerun.
* cfg.mk (_update_required): Likewise.
Since cppi is not part of Fedora Core 12, the check is conditional:
without cppi, running 'make syntax-check' merely warns:
$ make sc_preprocessor_indentation
preprocessor_indentation
maint.mk: skipping test sc_preprocessor_indentation: cppi not installed
* cfg.mk (sc_preprocessor_indentation): New syntax-check rule.
(preprocessor_exempt): New macro, with first exemption.
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.
Another warning caught by coverity. Continue to perform best-effort
closing and resource release, but warn the caller about the failure.
* src/esx/esx_driver.c (esxClose): Return an error on failure to close.
All other uses of get_str_prop in this file that ignored
failure explicitly cast to void.
* src/node_device/node_device_hal.c (dev_create): Silence coverity
warning.
Requiring git 1.6.4, just for the optional GNULIB_SRCDIR support,
was too harsh. Resynchronize from gnulib.
* .gnulib: Import from latest gnulib.
* bootstrap: Re-synchronize from .gnulib/build-aux.
* bootstrap.conf: Drop git to 1.5.5.
* README-hacking: Document use of GNULIB_SRCDIR.
Copy the latest gnulib bootstrap, which runs autoreconf and
generates po/Makevars for us. Other improvements include some
improved prerequisite tool checking.
This also fixes a bug in the .pot files, regarding the copyright holder.
* bootstrap: Update to version in .gnulib/build-aux.
* bootstrap.conf (MSGID_BUGS_ADDRESS, COPYRIGHT_HOLDER, SKIP_PO)
(gnulib_mk, ACLOCAL, bootstrap_epilogue): Provide overrides.
* autogen.sh (autoreconf): Avoid redundant autoreconf if bootstrap
was run.
* po/Makevars: Delete, now that bootstrap creates it.
* po/.gitignore: Update.
Borrow ideas from gnulib/build-aux/bootstrap, in order to factor the
specifics of libvirt into bootstrap.conf, while allowing future
upgrades of bootstrap to happen with less effort.
* bootstrap (gnulib_tool): Update invocation to be closer to
gnulib's version. Move libvirt specifics...
* bootstrap.conf: ...into new file.
