enable build for ocaml bytecode
by Olaf Hering
This is a first attempt to build libguestfs with just a ocaml bytecode
compiler. The three tools written in ocaml will be build only when an
ocamlopt compiler is available.

[PATCH] sysprep: handle distro specific sysv scripts
by Olaf Hering
Currently firstboot would only work on redhat-based images.
Handle redhat-based, suse-based and debian guests, error out in case of an
unknown distro.
Update firstboot.sh:
- make sure scripts exists and can be executed
- add LSB header to avoid insserv warnings later on
- run script only if called with "start"
Update functions, pass only required options.

virt-sparsify & TMPDIR
by Evaggelos Balaskas
I use my "custom" TMPDIR variable with virt-sparsify.
I just type:
export -p TMPDIR=/mnt/vm/tmpdir
I do that for a couple reasons:
either my /tmp is on a ramdisk or /tmp is on my (ssd) rootfs and i
dont want to "full" my / with the temporally files.
Thats said, i was thinking to "ask" OR sending a patch for adding a
tmpdir OPTION for virt-sparsify
like
virt-sparsify -t /mnt/vm/tmpdir f18.qcow2 f18.qcow2.spars
before contribute .... i was eager to ask for your thoughts.
Do you believe this would be useful or too much trouble for nothing ?
Do you believe that we could use a TMPDIR option for liguestfs in general ?
Thank you

[PATCH] tests: Handle changing QEMUDIR
by Cole Robinson
qemu-wrapper isn't regenerated if QEMUDIR is changed, so just
delete it and force regeneration.
Additionally we can drop the silent binary check, since
check-with-upstream-qemu-1 already does a similar test with --version
that will actually report an error to the user.

[PATCH] Make internal-only functions and structures private
by Matthew Booth
Certain functions are intended to be internal only, but we currently
export them anyway. This change moves them into a separate section of
guestfs.h protected by a GUESTFS_PRIVATE variable. This change also
enables private structs, but doesn't implement any.
This change only affects the C api. Language bindings aren't affected,
but probably should be in the future.

[PATCH] build: Fix haskell dependencies and parallel build

Without this change all the tests in the haskell bindings are rebuilt
every time. The primary motivation for this change is to fix this.
The fix for the above also allows parallel builds to be re-enabled.

[PATCH 0/3] Use __attribute__((cleanup(...)))
by Richard W.M. Jones
This patch series changes a small part of the library to use
__attribute__((cleanup(...))) to automatically free memory when
pointers go out of the current scope.
In general terms this seems to be a small win although you do have to
use it carefully. For functions where you can completely get rid of
the "exit code paths", it can simplify things. For a good example,
see the 'inspect-icon.c:icon_windows_xp' function before and after the
change. For most functions there is no change or a minor
simplification.
It can however cause problems if you accidentally put a CLEANUP_FREE
annotation on a pointer which is actually returned from the function,
or if you explicitly free something.
If we make this change, then the library will leak memory when
compiled with something that isn't GCC/LLVM. It's likely we have
other dependencies on GCC, since we've never seriously tried compiling
the library with any other compiler.
