Allow settings (an arbitrary list of strings) to be passed to the
current backend. This will allow us to tweak how the backend works,
eg. by forcing TCG.
Replaces code such as:
fd = open "test1.img"
ftruncate fd, size
close fd
g.add_drive "test1.img"
with the shorter and simpler:
g.add_drive_scratch size
These set or get the program name in the handle. Most programs
will never need to call this, since we set this, if possible,
using the glibc 'program_invocation_short_name(3)' feature.
This large, but mainly mechanical commit, renames "attach method"
everywhere to "backend".
Backwards compatibility of the API (guestfs_{set,get}_attach_method)
and environment (LIBGUESTFS_ATTACH_METHOD) is maintained, but in new
code use guestfs_{set,get}_backend and LIBGUESTFS_BACKEND instead.
The default backend (launching qemu directly) is now called 'direct'
instead of 'appliance', although you can still use 'appliance' as a
synonym.
(Not entirely sure whether using Gnulib to replace standard functions
is a good idea at all.)

Because of evolution of the code, if the user used the --qemu or
--qemudir options, libguestfs-test-tool would segfault because
guestfs_set_qemu was being called before the guestfs handle was
opened.
Change the code so this doesn't happen, and also remove the global 'g'
variable to make the code a bit more robust.
Bug found by Amit Shah.
These configure flags enable code profiling (with gprof) and code
coverage (with gcov) respectively.
Although this is a nice idea, it's not currently very useful.
Libtool mangles filenames in such a way that gcov cannot locate its
datafiles.
Profiling is of dubious utility with libguestfs which is not CPU-bound
and relies extensively on running external programs (oprofile-like
system profiling that took into account libguestfs + qemu or
libguestfs + qemu + the appliance + filesystem tools *would* be
useful).
Also neither flag will help in capturing data from the appliance.
'make extra-tests' was a monolithic set of tests that did all sorts of
things: valgrind, tests over local guests, tests with upstream qemu,
tests with upstream libvirt, tests with the appliance attach method.
This made it hard to perform individual tests, eg. just valgrind
testing. It was also hard to maintain because the tests were not
located in the same directories as the programs and sometimes
duplicated tests that were run elsewhere.
This commit splits up 'make extra-tests' into 5 separate targets:
make check-valgrind # run a subset of tests under valgrind
make check-valgrind-local-guests # test under valgrind with local guests
make check-with-appliance # test with attach-method == appliance
make check-with-upstream-qemu # test with an alternate/upstream qemu
make check-with-upstream-libvirt # test with an alternate/upstream libvirt
(You can also still run 'make extra-tests' which is now simply
a rule that runs the above 5 targets in order).
This replaces everything that was in the tests/extra directory,
so that has now gone.
Everyone ignores the documentation. Everyone ignores me even
when I specifically tell them to include the complete output.
Place a prominent notice at the beginning of the output.
On Linux PATH_MAX is 4096, but on some platforms it can be much larger
or even not defined (ie. unlimited). Therefore using a PATH_MAX-sized
stack buffer is not a great idea for portable programs.
This change removes use of PATH_MAX-sized stack-allocated buffers.
This change only applies to the library and standalone programs.
Inside the daemon, memory allocation is much more complicated so I
have not changed those (yet).

This adds standard LICENSE and BUGS sections to all of the man pages
that are processed by podwrapper.
Modify all the calls to $(PODWRAPPER) to add the right --license
parameter according to the content. Note that this relaxes the
license on some code example pages, making them effectively BSD-style
licensed.

Ensure each man page contains consistent COPYRIGHT and AUTHOR
sections.
Remove the LICENSE section. We will add that back in podwrapper in a
later commit.
Since our minimum supported version is now 1.16 and mount was fixed in
1.13.16, it is now safe to replace mount-options + empty options with
mount wherever it occurs.
The new API splits orderly close into a two-step process:
if (guestfs_shutdown (g) == -1) {
/* handle the error, eg. qemu error */
}
guestfs_close (g);
Note that the explicit shutdown step is only necessary in the case
where you have made changes to the disk image and want to handle write
errors. Read the documentation for further information.
This change also:
- deprecates guestfs_kill_subprocess
- turns guestfs_kill_subprocess into the same as guestfs_shutdown
- changes guestfish and other tools to call shutdown + close
where necessary (not for read-only tools)
- updates documentation
- updates examples
gettextize provides a local file called "gettext.h". Remove this and
use <libintl.h> from glibc headers instead.
Most of this change is mechanical: #include <libintl.h> in every C
file which uses any gettext function. But also we remove the
gettext.h file, and adjust the "_" macros.
Note that this effectively removes the ./configure --disable-nls
option, although we don't know if that ever worked.
