This experimental feature allowed you (in theory) to connect to an
existing instance of the libguestfs daemon. (Again, in theory) it
allowed you to attach to running guests. This didn't work well in
practice. If you want to do this, install qemu-guest-agent inside
your guest instead.
This also disables the --live options in guestfish and guestmount.
(The option now prints an error).
This was never supported in RHEL.
The daemon tests relied on this connection method to perform tests on
a bare daemon, so this removes those tests. They were not especially
valuable.

As part of our efforts to clean up and simplify libguestfs, removing
gnulib deletes a large dependency that we mostly no longer use and
causes problems for new users trying to build the library from source.
A few modules from gnulib are still used (under a compatible license)
and these are copied into gnulib/lib/
This brings libguestfs into line with other projects which have a
separate include/ directory for the public header.
It's also the case that <guestfs.h> has never particularly belonged in
the lib/ subdirectory. Some tools add -Ilib/ but they only need
<guestfs.h> and not any other headers from that directory, and
separating out the public header allows us to clean those up. This is
certainly the case for examples, and some language bindings and some
tests.
In future I'm hopeful we can use this as the basis to tease out other
dependencies, as a prelude to separating them out from the repo.
Add a simple way to do not even provide prototypes of deprecated
functions in the C library: this way, users (like our tools) can build
against the library making sure to not use any deprecated function, not
even when compiler deprecation warnings are disabled.
Add it to the majority of our tools/internal libraries, and make sure
that it is not defined when building the API bridges of our bindings.
The majority of the tools have already options (--echo-keys &
--keys-from-stdin) to deal with LUKS credentials, although there is no
way to automatically provide credentials. --keys-from-stdin is
suboptimal, because it is a usable solution only when there is just one
device to open, and no other input passed via stdin to the tool (like
the commands for guestfish).
To overcome this limitation, introduce a new --key option in tools:
* --key /dev/device:file:/filename/with/key
* --key /dev/device:string:the-actual-key
this way it is possible to pass all the credentials needed for the
specific devices to open, with no risk of conflict with stdin, and also
in a secure way (when using the "file" way).
On the technical side: this adds a new "key_store" API for the C tools,
making sure it is used only when needed. Partially mirror it also for
the OCaml tools, although there will be a conversion to the C API
because the decryption helpers used are in the common C parts.
The guestfish prepared disks (-N option) all defaulted to 100M. This
has always been too small for btrfs (so for example ‘-N fs:btrfs’ has
failed for a long time), and can be too small for LVs with new LVM2 /
kernel >= 4.16.
This changes the default from 100M to 1G. The beginning of the 1.39
branch seems like a good time to make this change.
virt-builder-repository allows users to easily create or update
a virt-builder source repository out of disk images. The tool can
be run in either interactive or automated mode.
Since glibc-2.26 removed the /usr/include/rpc/rpc.h, it caused problem even
though probing for libtirpc has taken place and worked properly. The problem is
that RPC_CFLAGS (usually `-I/usr/include/tirpc` on Linux) was not used in places
where it was needed. So the build failed with messages like the following:
In file included from guestfs_protocol.c:6:0:
guestfs_protocol.h:9:10: fatal error: rpc/rpc.h: No such file or directory
#include <rpc/rpc.h>
^~~~~~~~~~~

The device name is only used by guestfish (when using the -N option to
prepare drives). We constructed the device name very naively,
basically ‘sprintf ("/dev/sd%c", next_drive)’.
This stores the device index instead, and only constructs the device
name in guestfish. Also the device name is constructed properly using
guestfs_int_drive_name so it can cope with #drives > 26.
As a side effect of this change we can remove the extra parameter of
the add_drives macro.

Only in end-user messages and documentation. This change was done
mostly mechanically using the Perl script attached below.
I also changed don't -> don’t etc and made some other simple fixes.

glibc in Fedora is currently configured with `--enable-obsolete-rpc',
so I guess we can see which way the wind is blowing.
(1) This changes our configure script to prefer libtirpc if it is
available.
If libtirpc is _not_ available then:
(a) Headers must be located in <rpc/xdr.h>, or the user must supply
the right CFLAGS.
(b) XDR functions must be located in one of -lportablexdr, -lrpc,
-lxdr, -lnsl or no library at all (ie. -lc), and the user must set
LDFLAGS if needed.
(2) We no longer add these paths automatically to $(CFLAGS)/$(LIBS).
Any part of libguestfs which needs <rpc/*.h> or the xdr_* functions
must use $(RPC_CFLAGS)/$(RPC_LIBS) explicitly.
(3) Previously Mac OS X had a workaround for the broken 64 bit support
in the supplied rpcgen. This workaround "activates" all the time if
you use tirpc, so breaking Linux after the above changes. tirpc is
supported on OS X, so I think it's just better to use that rather than
the broken rpcgen. For that reason I removed the workaround
completely.

Apply this change across all the shell scripts containing tests.
Additionally this defines the environment variables $abs_srcdir,
$abs_builddir, $top_srcdir, $top_builddir, $abs_top_srcdir and
$abs_top_builddir which can now be used throughout test scripts.
Commit 004de6cf45 was not sufficient to
solve this problem. We are also using gperf in guestfish. Rewrite
the code in the same way to avoid having to prototype the hash
function.
Generate the random filename using our utility function
guestfs_int_random_string. This also means that we will not need to
call srandom() in guestfish or virt-edit.
Three more pieces of common code are moved under the common/
subdirectory. This is just code motion.
Note that windows.[ch] wasn't even being used by guestfish. That code
was only used in other virt tools.
This is mostly code motion but:
(1) I had to remove the compile-time COMPILING_GUESTFISH and
COMPILING_VIRT_RESCUE macros and replace them with runtime constants
and checks.
(2) I moved the fish/config.c file into this library.
Just code motion.
This commit makes it clearer what is a utility and what is part of the
library. It also makes it clear that we should rename:
guestfs-internal-frontend.h -> utils.h
guestfs-internal-frontend-cleanups.h -> cleanups.h (?)
but this commit does not make that change.
Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
This makes a number of small changes to how the internal documentation
is generated and what can be documented.
Header files are now permitted to contain internal documentation.
This works in the same wasy as .c files.
Also documentation can be added for structs as well as functions.
This commit also adds documentation to some header files and structs,
and fixes a few places which contained broken header documentation.
