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.

Change guestfish so it uses xstrtoll to parse Int (31 bit)
parameters. This fixes two bugs on 32 bit platforms which
failed when long = 32 bits. long long = 64 bits on both.

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.

The previous fix didn't cope with ordinary warnings emitted by
qemu (eg. "open /dev/kvm: No such file or directory"). This
is a hopefully more complete fix for the problem.
See also commit 3cd7ce75f1ce5048a4d9f6aeaf66aff3194e1096.

The regression test for RHBZ#557655 would fail if debugging was
enabled, because debug output would get mixed up with the test
output.
To reproduce the error do:
LIBGUESTFS_DEBUG=1 make -C regressions TESTS=rhbz557655.sh check
This commit disables debug for just this test.

Current code uses atoi to parse the generator Int type and
atoll to parse the generator Int64 type. The problem with the
ato* functions is that they don't cope with errors very well,
and they cannot parse numbers that begin with 0.. or 0x..
for octal and hexadecimal respectively.
This replaces the atoi call with a call to Gnulib xstrtol
and the atoll call with a call to Gnulib xstrtoll.
The generated code looks like this for all Int arguments:
{
strtol_error xerr;
long r;
xerr = xstrtol (argv[0], NULL, 0, &r, "");
if (xerr != LONGINT_OK) {
fprintf (stderr,
_("%s: %s: invalid integer parameter (%s returned %d)\n"),
cmd, "memsize", "xstrtol", xerr);
return -1;
}
/* The Int type in the generator is a signed 31 bit int. */
if (r < (-(2LL<<30)) || r > ((2LL<<30)-1)) {
fprintf (stderr, _("%s: %s: integer out of range\n"), cmd, "memsize");
return -1;
}
/* The check above should ensure this assignment does not overflow. */
memsize = r;
}
and like this for all Int64 arguments (note we don't need the
range check for these):
{
strtol_error xerr;
long long r;
xerr = xstrtoll (argv[1], NULL, 0, &r, "");
if (xerr != LONGINT_OK) {
fprintf (stderr,
_("%s: %s: invalid integer parameter (%s returned %d)\n"),
cmd, "size", "xstrtoll", xerr);
return -1;
}
size = r;
}
Note this also fixes an unrelated bug in guestfish handling of
RBufferOut. We were using 'fwrite' without checking the return
value, and this could have caused silent failures, eg. in the case
where there was not enough disk space to store the resulting file,
or even if the program was interrupted (but continued) during the
write.
Replace this with Gnulib 'full-write', and check the return value
and report errors.

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 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

/bin/sh on Debian is a minimal shell called 'dash' which doesn't
support some features we need such as the particular 'function'
syntax used by regressions/test-stringlist.sh, and therefore
this script was failing on Debian.
Change all of these scripts to use #!/bin/bash explicitly to avoid
these sorts of problems.

This adds a new API call guestfs_find0, which is like guestfs_find
but mainly doesn't suffer from the protocol limit of the earlier
command. The earlier command is not deprecated because it is
still very useful.
guestfs_find0 uses a FileOut parameter and writes the results to
an external file. The filenames in the output are separated by
ASCII NUL characters (so a bit like "find -print0").
There is also the addition of a regression test for this command.

This change adds the ability to group entries in a string list with single
quotes. So the string:
"'foo bar'"
becomes 1 token rather than 2. Consequently single quotes must now be escaped:
"\'"
resolves to a literal single quote.
Incidentally, this change also alters another, probably unintentional behaviour
of the previous implementation, in that tokens are separated by any amount of
whitespace rather than a single whitespace character. I.e.:
"a b"
resolves to:
'a' 'b'
rather than:
'a' '' 'b'
That last syntax can be used if an empty argument is still desired. Whitespace
is now also defined to include tabs.
parse_string_list can also now fail if it contains an unmatched open quote.

guestfish --listen necessarily redirects its stdout to /dev/null so as not to
interfere with eval. The remote protocol doesn't contain any other provision for
collecting stdout for the caller, so executing guestfish --remote will never
generate any output.
This patch fixes that by forwarding the caller's STDOUT to the listener over the
unix socket connection. The listener redirects its STDOUT to the caller's STDOUT
for the duration of the command, then closes it again.

'll' command has changed semantics very slightly
(see commit 6727e7c8bdf1cb39264a9de6333d228b51c39956).
We need to fix this test so it doesn't try to run
the ll command without a mounted disk.

This commit implements the RBufferOut type for returning
arbitrary 8 bit data from calls.
We also implement the guestfs_read_file call to read a
whole file that can contain any 8 bit content, but up to
a limit of ~ 2 MB.

The use case is to have a long-running guestfish process in
a shell script, and thus to avoid the overhead of starting
guestfish each time. Do:
eval `guestfish --listen`
guestfish --remote somecmd
guestfish --remote someothercmd
guestfish --remote exit
This patch also supports having multiple guestfish processes
at the same time.
The protocol is simple XDR messages over a Unix domain socket.

Test failure of qemu and recovery of the library:
- mid-command
- between commands
- during launch [test not working yet]
- explicitly killed by guestfs_kill_subprocess
Also this patch cleans up the other tests in this directory
and disables the long-winded test-bootbootboot test.
