guestfs_parse_environment_list.
Add a new function for creating a handle:
guestfs_h *guestfs_create_flags (unsigned flags [, ...]);
This variant lets you supply flags and extra arguments, although extra
arguments are not used at the moment.
Of particular interest is the ability to separate the creation of the
handle from the parsing of environment variables like
LIBGUESTFS_DEBUG. guestfs_create does both together, which prevents
us from propagating errors from parsing environment variables back to
the caller (guestfs_create has always printed any errors on stderr and
then just ignored them).
If you are interested in these errors, you can now write:
g = guestfs_create_flags (GUESTFS_CREATE_NO_ENVIRONMENT);
if (!g)
exit (EXIT_FAILURE);
r = guestfs_parse_environment (g);
if (!r)
exit (EXIT_FAILURE);
Also you can *omit* the call to guestfs_parse_environment, which
creates a handle unaffected by the environment (which was not possible
before).
This commit also includes new (backwards compatible) changes to the
OCaml, Perl, Python, Ruby and Java constructors that let you use the
flags.

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.

Previously with Python it was impossible to set a boolean or integer
optarg to -1 because that was used as a special sentinel value to
indicate that the optarg was not set.
Instead, use None as the sentinel value, since that cannot be a
boolean or integer type.

In libguestfs 1.20, you will be able to use 'add_drive'
instead of 'add_drive_opts' (except in the C bindings).
However until libguestfs 1.20 is the minimum stable version
people will still be using old versions where you have to use
'add_drive_opts'. This makes the examples confusing.
Therefore continue to use 'add_drive_opts' in the examples
for now.

This will allow us to easily change the location of this
script in future.

By using the once_had_no_optargs flag, this change is backwards

in earlier commit).

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
|
| |
|
|
|
|
|
| |
Make the comments consistent.
Also make the Perl example call $g->close explicitly so it is
consistent with the other examples.
|
| |
|
|
|
| |
This is now set by default in all supported versions of libguestfs.
It's just confusing if the examples refer to it.

This option, when added via
TESTS_ENVIRONMENT = [...] $(top_builddir)/run --test
allows us to run the tests and only print the full output (including
debugging etc) when the test fails.

Old KVM can't add /dev/null readonly. Treat /dev/null as a special
case.
We also fix a few tests where /dev/null was being used with
format=qcow2. This was always incorrect behaviour, but qemu appears
to tolerate it.

RHEL 5-era autoconf did not define these, so define them manually
when they are missing.
Define builddir as '.' The scripts require this. It won't work
in the srcdir != builddir case, but we don't care about that for
RHEL 5.
This commit also moves the builddir / abs_srcdir variable setting
above the include of subdir-rules.mk, in case that include uses
these variables.
Useful script:
for f in $(find -name Makefile.am | xargs fgrep '$(abs_srcdir)' -l) ; do
if ! grep -q '^abs_srcdir' $f; then
echo missing in $f
fi
done

'del g' is a trap for the unwary. If the handle has any other
references, it does nothing (in fact, it can be actively dangerous if
the user was expecting the appliance to go away). In non-CPython it
can be delayed arbitrarily long.
Using 'g.close()' on the other hand is always safe.

|

Also:
- tidy up the script
- use the ./run script when running Python tests

I noticed some uses of ${srcdir} in shell scripts.
That is almost always better written as $srcdir.
The patch below converts most such variable references.
Here are the few remaining candidates:
$ git grep -i -E '\$\{[a-zA-Z_0-9]+\}'|grep -v Makefile.in.in
configure.ac: JAR_INSTALL_DIR=\${prefix}/share/java
configure.ac: JNI_INSTALL_DIR=\${libdir}
debian/rules: for TEST in ${DEBIAN_SKIP_TEST}; do \
debian/rules:# mv $${mod} $$(dirname $${mod})/libguestfsmod.so; \
java/Makefile.am:libguestfs_jar_DATA = libguestfs-${VERSION}.jar
java/Makefile.am:libguestfs-${VERSION}.jar: $(libguestfs_jar_class_files)
perl/lib/Sys/Guestfs/Lib.pm: "-f", '${Package} ${Version} ${Architecture} ${Status}\n',
perl/typemap: croak (\"${Package}::$func_name(): called on a closed handle\");
perl/typemap: croak (\"${Package}::$func_name(): $var is not a blessed HV reference\");
tests/data/Makefile.am: echo "$${i}abcdefghijklmnopqrstuvwxyz"; \
We could change all of those, too, except the ones in configure.ac
and Makefile.am, since they refer to Make variables. Even those
should be changed, but to use the preferred Makefile notation:
$(prefix), $(libdir), $(VERSION).

Subject: [PATCH libguestfs] maint: use $var notation rather than ${var} when
possible
The only case to avoid in a shell script is when the byte after the
"}" is word-constituent, and concatenating it would thus change the
name of the variable.
These changes were induced by running this command:
git grep -l -i -E '\$\{(srcdir|md)' \
|xargs perl -pi -e 's/\$\{(srcdir|md)\}($|\w)/\$$1$2/gi'
The "g" was needed because there was one line with two instances.
The "i" is to handle ${SRCDIR}. The ($|\w) ensures that concatenating
whatever follows the "}" won't change semantics.

These fixes allow libguestfs bindings to work with Python 3 (tested
with Python 3.2)
You can select which Python you compile against by doing:
PYTHON=python ./configure && make && make check
or:
PYTHON=python3 ./configure && make && make check
|
| |
|
|
|
|
|
|
| |
If the user set PYTHON when configuring, this variable is not passed
through to the tests, so it is possible the tests will fail because
they are testing the wrong version of python. By passing $PYTHON
through to the tests we ensure that we test against the same version
of python that we configured with.

This avoids conflicts with the globally installed libguestfs
appliance, or lets us build in multiple local directories at the same

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.

We don't always want to install in the site-packages directory. Allow
the directory to be chosen using a configure option. Rename the
variable PYTHON_INSTALLDIR to reflect its true purpose.

This large commit changes the generator so that optional arguments
can be supported for functions.
The model for arguments (known as the "style") is changed from
(ret, args) to (ret, args, optargs) where optargs is a more limited
list of arguments.
One function has been added which takes optional arguments, it is
"add-drive-opts", modelled as:
(RErr, [String "filename"], #required
[Bool "readonly"; String "format"; String "iface"]) #optional
Note that this function is processed in the library (does not go over
the RPC protocol to the daemon). This has allowed us to simplify
the current implementation by omitting changes related to RPC or the
daemon, although we plan to add these at some point in the future.
From C this function can be called in 3 different ways as in these
examples:
guestfs_add_drive_opts (g, filename,
GUESTFS_ADD_DRIVE_OPTS_READONLY, 1,
GUESTFS_ADD_DRIVE_OPTS_FORMAT, "raw",
-1);
(the argument(s) between 'filename' and '-1' are the optional ones).
guestfs_add_drive_opts_va (g, filename, args);
where 'args' is a va_list. This works like the first version.
struct guestfs_add_drive_opts_argv optargs = {
.bitmask = GUESTFS_ADD_DRIVE_OPTS_READONLY_BITMASK,
.readonly = 1,
}
guestfs_add_drive_opts_argv (g, filename, &optargs);
This last form lets you construct lists of optional arguments, and
is used by guestfish and the language bindings.
In guestfish optional arguments are used like this:
add-drive-opts filename readonly:true
In OCaml these are mapped naturally to OCaml optional arguments, eg:
g#add_drive_opts ~readonly:true filename;
In Perl these are mapped to extra arguments, eg:
$g->add_drive_opts ($filename, readonly => 1);
In Python these are mapped to optional arguments, eg:
g.add_drive_opts ("file", readonly = 1, format = "qcow2")
In Ruby these are mapped to a final hash argument, eg:
g.add_drive_opts("file", {})
g.add_drive_opts("file", :readonly => 1)
g.add_drive_opts("file", :readonly => 1, :iface => "virtio")
In PHP these are mapped to extra parameters. This is not quite
accurate since you cannot omit arbitrary optional parameters, but
there's not much than can be done within the limitations of PHP
as a language.
Unimplemented in: Haskell, C#, Java.

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 changes guestfs_launch so that it both launches
the appliance and waits until it is ready (ie. the daemon communicates
back to us).
Since we removed the pretence that we could implement a low-level
asynchronous API, the need to call launch() followed by wait_ready()
has looked a bit silly.
Now guestfs_wait_ready() is basically a no-op. It is left in the
API for backwards compatibility. Any calls to guestfs_wait_ready()
can be removed from client code.
