This checks all available optional groups and prints out which
ones are supported by the daemon. Note you must launch the appliance
first.
Example:
><fs> supported
augeas yes
inotify yes
linuxfsuuid yes
linuxmodules yes
linuxxattrs yes
lvm2 yes
mknod yes
ntfs3g yes
ntfsprogs yes
realpath yes
scrub yes
selinux yes
xz yes
zerofree yes

This adds additional tests to check that several types of parameter
including String are not NULL when passed to the C functions.
Previously this would cause a segfault inside libguestfs. With
this change, you get an error message / exception.
Of the possible pointer parameters, only OptString is now permitted
to be NULL.
This change does not affect the Perl bindings. This is because Perl
XS code was already adding similar checks if you passed undef into
a parameter expecting a string.

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.

Previously you might have typed:
$ guestfish
><fs> alloc test1.img 100M
><fs> run
><fs> part-disk /dev/sda mbr
><fs> mkfs ext4 /dev/sda1
now you can do the same with:
$ guestfish -N fs:ext4
Some tests have also been updated to use this new
functionality.

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.

These calls allow you to query the relationship between
LVM objects, for example, which PVs contain a VG, or which
LVs are contained in a VG.
See the example / test program 'regressions/test-lvm-mapping.pl'
for an example of how to do this from Perl.

libguestfs-supermin-helper was previously a shell script. Although
we had steadily optimized it, there were a number of intractable
hot spots:
(1) cpio still reads input files in 512 byte chunks; this is *very*
pessimal behaviour, particularly when SELinux is enabled.
(2) the hostfiles globbing was done very inefficiently by the shell,
with the shell rereading the same directory over and over again.
This is a rewrite of this shell script in C. It is approximately
3 times faster without SELinux, and has an even greater speed difference
with SELinux.
The main features are:
(a) It never frees memory, making it simpler. The program is designed
to run and exit in sub-second times, so this is acceptable.
(b) It caches directory reads, making the globbing of host files much
faster (measured this as ~ 4 x speed up).
(c) It doesn't use external cpio, but instead contains code to write
newc format cpio files, which is all that the kernel can read. Unlike
cpio, this code uses large buffers for reads and writes.
(d) Ignores missing or unreadable hostfiles, whereas cpio gave a
warning.
(e) Checks all return values from system calls.
(f) With --verbose flag, it will print messages timing itself.
This passes all tests.
Updated with feedback from Jim Meyering.

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.

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".

Start a new API allowing groups of functions to be tested for
availability.
There are two reasons for this:
(1) If libguestfs is built with missing dependencies (eg. no Augeas lib)
then the corresponding functions are disabled in the appliance. Up till
now there has been no way to test for this except to speculatively
issue commands and check for errors.
(2) When we port the daemon to Win32 it is likely that major pieces of
functionality won't be available (eg. LVM support). This API gives
a way to test for that.
There is no change for existing clients: you still have to check for
errors from individual API calls.
For new clients, you will be able to test for availability of particular
APIs.
Usage scenario (A): An LVM editing tool which requires
both the LVM API and inotify in order to function at all:
char *apis[] = { "inotify", "lvm2", NULL };
r = guestfs_available (g, apis);
if (r == -1) {
/* print an error and exit */
}
Usage scenario (B): A general purpose tool which optionally provides
configuration file editing, but this can be disabled, the result
merely being reduced functionality:
char *apis[] = { "augeas", NULL };
r = guestfs_available (g, apis);
enable_config_edit_menus = r == 0;

This commit introduces a generic partition creation interface
which should be future-proof and extensible, and partially
replaces the old sfdisk-based interface.
The implementation is based on parted but is hopefully not too
dependent on the particulars of parted.
The following new calls are introduced:
guestfs_part_init:
Initialize a disk with a partition table. Unlike the sfdisk-
based interface, we also support GPT and other partition
types, which is essential to scale to devices larger than 2TB.
guestfs_part_add: Add a partition to an existing disk.
guestfs_part_disk:
Convenience function which combines part_init & part_add,
creating a single partition that covers the whole disk.
guestfs_part_set_bootable:
guestfs_part_set_name:
Set various aspects of existing partitions.
guestfs_part_list:
List partitions on a device. This returns a programming-friendly
list of partition structs (in contrast to sfdisk-l which cannot
be parsed).
guestfs_part_get_parttype:
Return the partition table type, eg. "msdos" or "gpt".
The following calls are planned, but not added currently:
guestfs_part_get_bootable
guestfs_part_get_name
guestfs_part_set_type
guestfs_part_get_type

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).

truncate, truncate_size: Used to truncate files to a particular
size, or to zero bytes.
mkdir_mode: Like mkdir but allows you to also specify the
initial permissions for the new directory.
utimens: Set timestamp on a file with nanosecond accuracy.
lchown: Corresponding to lchown(2) syscall (we already have chown).
The implementation is complicated by the fact that we had to
add an Int64 parameter type to the generator.

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.

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.

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.
