Add a script which generates the 'BUGS' file from Red Hat Bugzilla.
This is run whenever we do 'make dist' and deliberately stored in git.

xgettext will only recognize '*.pl' as being a Perl file (otherwise
it treats it as a C file and does not correctly find any strings
in it).
This commit also fixes two actual bugs that xgettext found in the
strings in our Perl programs.

Virt-resize is the main contribution here, a program which can
be used to expand and shrink partitions in disk images.
Virt-list-partitions is used as an ancillary tool for planning
resize operations.

Use these on any platforms where you don't want or need to
build the daemon/appliance combination.

This commit makes the semi-independent hivex library into a
separate upstream project. The git repo for hivex is now:
http://git.annexia.org/?p=hivex.git;a=summary
Downloads of hivex are available here:
http://libguestfs.org/download/
All questions, patches, bugs etc should be sent to the libguestfs
mailing list and bug tracker.

These manual pages have for a very long time 'lived' in the top
source directory.
Clean up this situation by moving those manual pages (plus associated
generated files) into the src/ and fish/ subdirectories respectively.

Use this program as a convenient way to list the filesystems
available in a disk image or libvirt guest.
Example:
$ virt-list-filesystems /dev/vg_trick/Debian5x64
/dev/debian5x64/home
/dev/debian5x64/root
/dev/debian5x64/tmp
/dev/debian5x64/usr
/dev/debian5x64/var
/dev/sda1
This is designed to make it easier for novices to use guestfish
and guestmount. In particular with guestmount this acts as a way
to get a list of filesystems to use with the '-m' option. ie:
$ virt-list-filesystems unknowndisk.img
/dev/sda1
/dev/sda2
$ guestmount -a unknowndisk.img -m /dev/sda1 /mnt

The current groups are defined very conservatively using the
following criteria:
(a) Would be impossible to implement on Windows because of
sheer architectural differences (eg: mknod).
(b) Already optional (augeas, inotify).
(c) Not currently optional but not implemented on older RHEL and
Debian releases (ntfs-3g.probe, scrub, zerofree).
The optional groups I've defined according to these criteria are:
. augeas
. inotify
. linuxfsuuid
. linuxmodules
. linuxxattrs
. lvm2
. mknod
. ntfs3g
. scrub
. selinux
. zerofree
(Note that these choices don't prevent us from adding more
optional groups in future. On the other hand to avoid breaking
ABIs we would not wish to change the above groups).
The rest of this large commit is really just implementation:
Each optional function is classified using Optional "group"
flag in the generator.
The daemon has to implement a function
int optgroup_<name>_available (void);
for each optional group. Some of these functions are fixed at
compile time, and some do simple run-time tests.
The do_available implementation in the daemon looks up the correct
function in a table and runs it.
We document the optional groups in the guestfs(3) man page.
Also: I added a NOT_AVAILABLE macro in order to unify all the
existing places where we had a message equivalent to
"function __func__ is not available".

This change adds an explicit dependency on generator.ml for every file it
generates, except java files. Java is left for another time because it's
considerably trickier.
It also adds a build rule for src/libguestfs.la so it can be rebuilt as required
from other directories.
It does this by creating a top level make file, subdir-rules.mk, which can be
included from sub-directories. sub-directories need to define 'generator_built'
to include local files which are built by generator.ml, and they will be updated
automatically.
This fixes parallel make, and will automatically re-create generated files when
make is run from any directory.
It also fixes the problem which efad4f53 was targetting. Specifically,
src/guestfs_protocol.(c|h) had an erroneous dependency on stamp-generator, and
therefore generator.ml, despite not being directly created by it. This caused
them to be recreated every time generator.ml ran rather than only when
src/guestfs_protocol.x was updated, which cascaded into a daemon and therefore
appliance update.
This patch also changes the contents of the distribution tarball by including
files created by rpcgen.

This implements FUSE filesystem support so that any libguestfs-
accessible disk image can be mounted as a local filesystem.
Note: file writes (ie. write(2) system call) is not yet implemented.
The API needs more test coverage, particularly lesser-used system
calls.
The big unresolved issue is UID/GID mapping between guest filesystem
IDs and the host. It's not easy to automate this because you need
extra details about the guest itself in order to get to its
UID->username map (eg. /etc/passwd from the guest).

In hivex/: This mini-library allows us to extract Windows
Registry binary files ("hives").
There are also two tools: hivexml converts a hive to a
self-describing XML format. hivexget can be used to extract
single subkeys from a hive.
New tool: virt-win-reg. This is a wrapper around the library
functionality allowing you to pull out data from the registries
of Windows guests.

This tool makes available the functionality of "ls", "ll", and "find"
in a slightly simpler to use form.
Examples:
virt-ls -l myguest /tmp
|
|
|
|
|
|
|
|
|
|
|
|
| |
This adds a new tool call virt-tar which is a general purpose
archive and uploading tool. It doesn't add any functionality
which wasn't previously possible using guestfish, but makes it
simpler to access for some users.
Examples:
virt-tar -zx myguest /home home.tar.gz
virt-tar -zu myguest uploadstuff.tar.gz /tmp

This moves the tool programs into a single directory:
cat/* -> tools/virt-cat
df/* -> tools/virt-df
edit/* -> tools/virt-edit
rescue/* -> tools/virt-rescue
This in itself simplifies the build process because we only need
one Makefile and one copy of 'run-locally'.
'run-*-locally' has become just 'run-locally' and takes an extra
parameter which is the name of the tool, eg:
run-locally cat [virt-cat params...]
virt-inspector stays in its own directory, because this contains
more than just a single Perl script.

This commit adds a generic mechanism for deriving language bindings
for virt-inspector, and implements one concrete binding, for OCaml.
The bindings are generated from the RELAX NG schema (virt-inspector.rng)
which is supposed to be a correct and always up to date description
of the XML that the virt-inspector program can generate.
From the RNG we generate a set of types to describe the output of
virt-inspector for the language, plus an XML parser, plus some
glue code to actually run an external instance of virt-inspector
and parse the resulting XML.
At runtime, an external 'virt-inspector --xml <name>' command runs
and the XML is parsed into language-specific structures.
This has been tested on the four example files (inspector/example?.xml)
The only particular difficulty about the OCaml binding is the use of
Obj.magic, which is naughty but works because of the isomorphism
between the representation of tuples and records in OCaml. This
seems to cause no problems in my test program. Apart from this, the
OCaml binding is straightforward and could be adapted easily for any
other languages that want type-safe virt-inspector bindings.
It's important to keep virt-inspector.rng up to date with changes
to virt-inspector's XML output format.

A parallel build could fail due to the use in ocaml/examples
of ocaml/guestfs.cmi before it was built.
* Makefile.am (SUBDIRS): Add both ocaml and ocaml/examples,
to ensure they're built in this order, and not in parallel.
* ocaml/Makefile.am (SUBDIRS): Don't define.

Edit any file in a guest. This was possibly previously
using guestfish, but having a separate command makes it
simpler.
The usage is simply:
virt-edit mydomain /some/file
It runs $EDITOR or vi on the file, and if the user changes
it, uploads the result back to the VM.

This command runs a "rescue appliance" against a virtual machine
or disk image. This is useful for making ad-hoc interactive
changes to virtual machines.
$ virt-rescue --ro /dev/vg_trick/F11x64
Welcome to virt-rescue, the libguestfs rescue shell.
Note: The contents of / are the rescue appliance.
You have to mount the guest's partitions under /sysroot
before you will be able to examine them.

is sorted differently from the on that is checked in:

This is an end-user testing tool, designed to test basic functionality
of libguestfs/qemu/kernel combination on the end-user's final host
machine.
It does not perform a thorough test, but should be enough to find
most booting issues.
Also this is intended to be used when reporting bugs.

All Perl strings are now marked as translatable using __"string"
or __x("string {placeholder}", placeholder => $_). Perl strings
now get copied to the PO files.
The po/POTFILES.in file is now updated automagically whenever we
add new *.c, *.pl or *.pm files into the repository.
