Instead of explicitly calling umount-all; sync, we add a daemon
function called internal-autosync which does the same.
Apart from slightly simplifying the process of closing the handle, the
main advantage is we can modify the daemon for the standalone case so
that internal-autosync does not do the umount-all operation.

Also separate the call and return lines so that everything can be
easily 'grepped' from debug output. The trace output now looks like
this:
$ guestfish -x -N fs exit
libguestfs: trace: is_config
libguestfs: trace: is_config = 1
libguestfs: trace: add_drive "test1.img"
libguestfs: trace: add_drive = 0
libguestfs: trace: is_config
libguestfs: trace: is_config = 1
libguestfs: trace: launch
libguestfs: trace: launch = 0
libguestfs: trace: part_disk "/dev/sda" "mbr"
libguestfs: trace: part_disk = 0
&c.

This allows the -O parameter to be added to the mkfs command line.
This is used to select filesystem features.

Fix guestfish (and other C tools) so that they ignore errors
when /etc/fstab contains bogus entries.
Update the documentation for inspect-get-mountpoints to emphasize
that callers must be aware of this when mounting the returned
values.
Add a regression test.
Update the example code ("inspect_vm") to reflect the way this
API ought to be called.
For more detail see:

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 |.$..|
00000004
><fs> lgetxattr "/Documents and Settings" system.ntfs_reparse_data | hexdump -C

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.

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).

These tests run much more quickly if you don't have to run
'mkfs' and (particularly) partitioning/LV commands between each
test.
The total time for running 'make -C capitests check' on my laptop
has gone from 413 seconds down to 221 seconds.
|
|
|
|
|

This should allow us to perform filesystem-based write
tests much more quickly, because we don't need to recreate
the filesystem from scratch each time.
|

|
|

|

|

This change means that /dev/sdb is not being used during
the tests (except passively, eg. in listings of devices).
This allows us (in a forthcoming commit) to use /dev/sdb as a
quick scratch filesystem for testing writes.

This removes the dependency from guestfish to the external
pod2text program (and hence the final dependency on perl for
guestfish). This is done by storing the formatted pod2text
output in guestfish as the help text.

Allow extra width, and trimming options.
This necessitates a change in the memoized format. To avoid
causing crashes if a new generator loads the old format, also
change the filename of the memo file.

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.

Debian 5, Ubuntu 10.10, FreeBSD 8, Windows 7.

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.
|
|
|
|
| |
This APIs reimplement some parts of virt-inspector in C.

Include the XDR headers in the internal guestfs-internal.h instead.
This is knock-on effects to several other source files which
were implicitly relying on indirectly loaded headers.

At some point we removed the last thing that required
xml-light, but were still testing for it at various places
in the build. This removes all traces.
|
|
|
|
|
| |
This allows other libraries to redefine those typedefs
if they need to use but not depend on <guestfs.h>.
|
|
|
|
|
| |
This removes the 'not-quite-separate' guestfs-actions.h and
guestfs-structs.h files.

This new API allows you to add the disks from a libvirt
domain.
In guestfish you can use the 'domain' command to access the
API, eg:
><fs> domain Fedora14 libvirturi:qemu:///system
1
The returned number is the number of disks that were added.
Also here is a proposed (but commented out) low-level API
which would allow you to add a domain from a virDomainPtr.
However there are several problems with this API -- see discussion
on the list:

This allows generic "foo *bar" pointers to be passed to
library functions (not to daemon functions).
In the language bindings (except Perl) these are handled
as generic int64s with the assumption being that any
pointer can be converted to and from this. There is room
to add specific support for some pointer types in future
by specializing the match cases. However this is inherently
tricky because it depends on the implementation details of
other bindings (eg. to support virDomainPtr in OCaml depends
on the implementation details of the ocaml-libvirt project).
Perl is slightly different in that you have to supply a
typemap. Again this would depend on the implementation
detail of an external library unless you supplied a generic
typemap for int64.

This is an internal-only debugging API so may be changed or
removed at any time in the future.

Return the roots found by the last call to inspect-os, but
without redoing the whole inspection.
