Because we didn't match on word boundaries, the previous
code would get confused by similar APIs, eg. getxattr vs getxattrs.
|
|
|
|
|
|
| |
Add a new section called "EXTENDING LIBGUESTFS" to the
guestfs manual page which contains all the information
previously in "HACKING".

These APIs are essentially required to work around a problem
with ntfs-3g. This filesystem (or FUSE?) does not list all
extended attributes of a file when you call listxattr(2). However
if you know the name of an extended attribute, you can retrieve
it directly using getxattr(2).
The current APIs (getxattrs etc) are simple to use, but they
don't work if we can't list out the extended attributes (ie.
by calling listxattr(2)).
Example using the new APIs on an ntfs-3g filesystem:
><fs> lgetxattr "/Documents and Settings" system.ntfs_attrib | hexdump -C
00000000 16 24 00 00 |.$..|

This could be used to touch an arbitrary file (albeit one which
must already exist), and this could have been a security problem.

This change resolves several issues with current appliance
building:
(1) Old appliances are cleaned up.
(2) Race conditions between appliance building is handled better.
(3) Several bugs fixed.

(Revealed by compiling under Debian where this is a warning).

With the new package building system, it is no longer dangerous to run
'configure', 'make' or 'make check' as root (although it is still not
necessary and not advisable). In any case we don't need to check
this.

This removes all support for building the ordinary / old
style appliance using febootstrap 2.x, debootstrap, debirf,
fakeroot and fakechroot.
Instead this uses febootstrap 3.x to build the supermin appliance
in a simpler cross-distro manner.
|
|
|
|
| |
This file is not used for building the supermin appliance.

This is an extensible version of 'mkfs' which supports optional
arguments. There is now no need for 'mkfs_b' since you should
use 'mkfs_opts' with the optional 'blocksize' argument instead.
|

Previously we only supported optional arguments for library
functions (commit 14490c3e1aac61c6ac90f28828896683f64f0dc9).
This extends that work so that optional arguments can also be
passed through to the daemon.
|
|
|
|
|
|
|
| |
If the daemon sends progress notification messages while we
are uploading FileIn parameters, these are received in
check_for_daemon_cancellation_or_eof. Modify this library
function so that it turns these messages into callbacks.

We've not actually hit this bug in practice, but at least in
theory while checking for cancellation we could read > 0 but
fewer than 4 bytes, which would effectively be discarded and
we would lose synchronization.
Note the socket is non-blocking.
Change the code so that we temporarily set the socket back to
blocking and force the read of all 4 bytes.
|
|
|
|
|
|
| |
For actions that have FileIn arguments, count the size of all
the input files and send that in the progress_hint field of the
request header.

Two unrelated changes to the protocol to support progress
messages during uploads, and optional arguments.
Note that this makes an incompatible change to the protocol,
and this is reflected in the protocol version field (3 -> 4).

This private function (not part of the API) allows us to
iterate over disks from a guest, avoiding the business of
writing all the XPath code yet again.

If db_dump is not available then disable RPM application detection.
Note these utilities have odd names on Debian.

This tool replaces virt-list-filesystems and virt-list-partitions with
a new tool written in C with a more uniform command line structure
and output.
This existing Perl tools are deprecated but remain indefinitely.

This fixes a memory leak introduced by
commit fab75c0337d7897d10ea5e95e47ac05eab81ace9.

This returns the hostname of the guest. Tested on RHEL, Fedora,
Debian 5, Ubuntu 10.10, FreeBSD 8, Windows 7.

This is just code motion.

This converts the current Perl code in virt-inspector for
listing applications, into C, making it a part of the core API.
This is also capable of fetching the list of Windows applications
from the registry.

Linux Mint is derived from Ubuntu.
Mandriva has a release file, but it also has /etc/lsb-release and
the same parsing code can be reused. Mandriva has a package manager
called urpmi.

This adds inspection support for FreeBSD.
However this is not quite enough to allow guestfish -i freebsd.img
to work, because guestfish will try to mount the filesystems,
which cannot be done because Linux requires special mount options
for the Universal Filesystem (UFS) used by *BSD. Nevertheless
you can manually run the same commands.

Avoid duplicate checks for things like /etc and /bin.
