* cfg.mk (sc_prohibit_trailing_blank_lines): Delete; this is
adequately covered by maint.mk's sc_prohibit_empty_lines_at_EOF.
* .x-sc_prohibit_empty_lines_at_EOF: New file, to exempt raw
patches.
* Makefile.am (EXTRA_DIST): Include new exemption.
There has been a frequent complaint of:
make[2]: Entering directory `/home/remote/eblake/libvirt/po'
make[2]: *** No rule to make target `/config.status', needed by `Makefile'. Stop.
It happens after nuking and regenerating the po directory,
which is a common action after running anything like
'make dist' or 'make rpm' that dirties all the .po files.
Teach autogen.sh that it must regenerate po/Makevars to avoid
the missing variable declaration, and teach cfg.mk to recognize
that a nuked po directory is cause to rerun autogen.sh.
* cfg.mk (_update_required): Check for po/Makevars.
* autogen.sh (bootstrap): Run bootstrap if it got lost.

Since we are adding a new "per-hypervisor" protocol, we
make it so that the qemu remote protocol uses a new
PROTOCOL and PROGRAM number. This allows us to easily
distinguish it from the normal REMOTE protocol.
This necessitates changing the proc in remote_message_header
from a "remote_procedure" to an "unsigned", which should
be the same size (and thus preserve the on-wire protocol).
Changes since v1:
- Fixed up a couple of script problems in remote_generate_stubs.pl
- Switch an int flag to a bool in dispatch.c
Changes since v2:
- None
Changes since v3:
- Change unsigned proc to signed proc, to conform to spec
Signed-off-by: Chris Lalancette <clalance@redhat.com>
V2:
- Move bitmap impl to src/util/bitmap.[ch]
- Use CHAR_BIT instead of explicit '8'
- Use size_t instead of unsigned int
- Fix calculation of bitmap size in virBitmapAlloc
- Ensure bit is within range of map in the set, clear, and get
operations
- Use bool in virBitmapGetBit
- Add virBitmapFree to free-like funcs in cfg.mk
V3:
- Check for overflow in virBitmapAlloc
- Fix copy and paste bug in virBitmapAlloc
- Use size_t in prototypes
- Add ATTRIBUTE_NONNULL in prototypes where appropriate
and remove NULL check from impl
V4:
- Add ATTRIBUTE_RETURN_CHECK in prototypes where appropriate.
* cfg.mk (sc_prohibit_gettext_markup): New rule, to enforce
this policy. Contrary to most diagnostic-emitting functions,
where we require _(...) markup, here, we require that _() *not*
be used for certain functions (or function-like macros).
This makes the useless-if-before-free test in maint.mk spot
uses of virCgroupFree just like it does for free and the other
listed functions.
* cfg.mk (useless_free_options): Add virCgroupFree.
Prompted by suggestion from Eric Blake.
Some shells warn about missing programs before redirection;
the idiomatic way to silence them is to run the program check
inside a subshell, with the redirections outside the subshell.
But a subshell is only needed in places where it is reasonable
to expect the use of such a noisy shell in the first place.
* src/Makefile.am (remote_protocol-structs): Use subshell, for
FreeBSD 8.0 /bin/sh.
* cfg.mk (sc_preprocessor_indentation): Avoid subshell, since the
only users running cfg.mk can be assumed to have decent tools.
Noticed because virt-pki-validate was very inconsistent on
using tabs vs. 8 spaces, sometimes mixing both paradigms on
a single line.
'git diff -b' shows significant changes only in cfg.mk.
* cfg.mk (sc_TAB_in_indentation): Add a few files.
* daemon/libvirtd.init.in: Avoid tabs.
* tools/virt-pki-validate.in: Likewise.
Remove symbols that don't exist anymore (e.g. ERROR0) or aren't
message generating functions (e.g. VIR_FREE) or are now reported
as unmarked because the grep command is different, but that should
not be marked at all (e.g. DEBUG0).
Also don't restrict one of the grep lines in the
libvirt_unmarked_diagnostics rule to match exactly one space
between function name and opening parenthesis.
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.
Also define ESX_ERROR and ESX_VI_ERROR in a central place, instead of
defining them in each source file.
Add ESX_ERROR and ESX_VI_ERROR to the msg_gen_function list in cfg.mk.
Update po/POTFILES.in accordingly.

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.
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.
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.
* 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.
The latter is not officially "wrong", but *is* terribly anachronistic.
I think automake documentation or comments call that syntax obsolescent.
* cfg.mk (_makefile_at_at_check_exceptions): Exempt @SCHEMADIR@
and @SYSCONFDIR@ uses -- there are no Makefile variables for those.
* docs/Makefile.am: Use $(INSTALL), not @INSTALL@.
* examples/dominfo/Makefile.am: Similar.
* examples/domsuspend/Makefile.am: Similar.
* proxy/Makefile.am: Similar.
* python/Makefile.am: Similar.
* python/tests/Makefile.am: Similar.
* src/Makefile.am: Similar.
* tests/Makefile.am: Similar.
We should always be using virGetHostname in place of
gethostname; thus add in a new syntax-check rule to make
sure no new uses creep in.

Make a pass over the syntax-check files, tightening up regex's,
un-ignoring certain files, and cleaning things up.

* cfg.mk: use $(srcdir)/ prefix for Makefile.nonreentrant include
* examples/domain-events/events-c/Makefile.am tools/Makefile.am
examples/hellolibvirt/Makefile.am: extend the include paths to
use $(top_srcdir)/include too.
Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

The code in cfg.mk to detect when the git submodule was out of date
worked most of the time, but not when checked out in a certain way.
* cfg.mk: Extract submodule hash from command output and file,
and compare only that, since the format of the full line may vary.
Reported by Mike Burns, with some diagnosis by Daniel P Berrange.
This makes "make syntax-check" fail when a version-controlled
file contains a trailing blank line.
* cfg.mk (sc_prohibit_trailing_blank_lines): New rule.
