1f980d1b10 build: Set TMPDIR for local testing.
This avoids conflicts with the globally installed libguestfs
appliance, or lets us build in multiple local directories at the same
time without conflicts.

Cherry picked from commit f7d18c84dd
and backported to stable-1.10 branch.

9ba4136a65 Remove local LIBGUESTFS_PATH detection from guestfish and guestmount.
Remove the hack that let you run ./fish/guestfish or
./fuse/guestmount.  You now have to do:

  ./run ./fish/guestfish
or
  ./run ./fuse/guestmount

to run these programs without installing.

0d6fd9e1d2 fuse: Fix getxattr, listxattr calls and add a regression test (RHBZ#691389).
The documentation for the getxattr and listxattr calls is not very
clear and as a result we were always returning something different
from that which the Linux kernel would usually return.

This fixes these calls, at least far enough that both the 'getfattr'
and 'getfacl' programs now work fine on FUSE-mounted filesystems.

Note that SELinux attrs are *not* passed through.  This appears to be
a known bug between SELinux and FUSE.  For more information see:

nothing.  This patch is intended for backporting to the

which use 'guestfish --rw'.

a232e62dcf fish: '-i' option automatically handles whole-disk encryption.
This feature is also available in guestmount because of the
shared option parsing code.

You don't need to do anything to enable it, just using -i
will attempt decryption of encrypted partitions.

Only works for simple Fedora whole-disk encryption.  It's a
work-in-progress to make it work for other types of encryption.

c66d6f215e Unify guestfish and guestmount options processing (RHBZ#642932).
In guestfish, factor out the processing of the options -a, -c,
-d, -i, -m, -n, -r, -v, -V, -x into a separate set of files:
options.c, options.h, inspect.c, virt.c.

Change guestmount so that it uses these same files (from the
../fish directory) to process the same options.

This unifies the handling of these options between the two programs.
It also adds the useful inspection feature to guestmount, so you
can now do:

  guestmount -d Guest -i --ro mnt/

4932fdca3c build: Don't add version extra string to the version number.
If this string was non-empty, then it broke a lot of things because
autoconf and other parts of the build system were expecting this
string to contain a simple MAJOR.MINOR.RELEASE version number.

This requires changes to guestfish and guestmount so they use the
guestfs_version API to fetch the version from the library.  (The
Perl tools were already doing it this way).  In a way this is more
accurate, because it's no longer hard-coded in the binary, but
fetched from the dynamically linked libguestfs.so.

3920ad95f6 New API: write for creating files with fixed content (RHBZ#501889).
The guestfs_write call can be used to create small files with
arbitrary 8 bit content, including \0 bytes.

This replaces and deprecates write-file, which cannot be modified
to use BufferIn because of an unfortunate choice in the ABI: the
size parameter to write-file, if zero, means that the daemon tries
to calculate the length of the buffer using strlen.  However this
fails if we pass a zero-length buffer using BufferIn because then
the daemon tries to do strlen on a (really) zero length buffer, not
even containing a terminating \0 character, thus segfaulting.

f93cbe5756 Use mount-options instead of mount to avoid implicit -o sync.
guestfs_mount adds -o sync implicitly.  This causes a very large
performance problem for write-intensive programs (eg. virt-v2v).

Document this as a "gotcha".

Change the tests, guestfish, Sys::Guestfs::Lib, guestmount to use
mount-options instead.

(Note that this gotcha does not affect mount-ro).

The source of the performance problem was first identified by
Matthew Booth.

a6025c11d9 Set locale in C programs so l10n works (RHBZ#559962).
This commit adds the calls to setlocale &c to all of the current
C programs.

It also adds l10n support to hivexget and hivexml which lacked them
previously.

To test this, try:

LANG=pa_IN.UTF-8 guestfish --cmd-help

(You can only do this test after installing the package, or at
least the 'pa.mo' mo-file in the correct place).

299d5b9dd2 New tool: virt-list-filesystems
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

c477e2fb78 build: Fix inter-directory dependencies
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.

f5a3da1483 generator: Fix API of functions that return RBufferOut
(NB: The API / ABI doesn't actually change here - it's just made much
simpler to use).

The API for RBufferOut functions was unexpectedly hard to use in the
case where a zero-length buffer might be returned.  For discussion on
this see:

https://www.redhat.com/archives/libguestfs/2009-November/thread.html#00115

This commit ensures that in the zero-length buffer case, the return
value is never NULL.  Thus code is now able to just check if the return
value == NULL to indicate an error, which is simpler for all concerned.

The implementation of this is, however, more complex because we have
to be careful about this case inside both the daemon and the library
code, which is what this commit does.

This has passed a full round of tests.
