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

Replace:
cp tests/guests/fedora.img test.img
with the longer but possibly more space-efficient equivalent:
qemu-img create -F raw -b tests/guests/fedora.img -f qcow2 test.qcow2

MALLOC_PERTURB_ is a glibc feature which causes malloc to wipe memory
before and after it is used, allowing both use-after-free and
uninitialized reads to be detected with relatively little performance
penalty:
http://udrepper.livejournal.com/11429.html?nojs=1
Modify the ./run script so that it always sets this.
We were already using MALLOC_PERTURB_ in most tests. Since ./run is
now setting this, we can remove it from individual Makefiles. Most
TESTS_ENVIRONMENT will now simply look like this:
TESTS_ENVIRONMENT = $(top_builddir)/run --test
|
|
|
|
|
|
|
| |
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 <libvirt.h> had a conflicting definition of virDomainGetXMLDesc:
fake_libvirt_xml.c:36: error: conflicting types for 'virDomainGetXMLDesc'
/usr/include/libvirt/libvirt.h:715: error: previous declaration of 'virDomainGetXMLDesc' was here
The difference is not material ('int' vs. 'unsigned int').
Avoid the error by not including <libvirt.h>.

By setting these variables, we can skip tests that fail on
RHEL 5.

This is missing on RHEL 5.

RHEL 5 didn't have the truncate command, but we can replace:
truncate -s SIZE FILE
with the roughly equivalent command:
guestfish sparse FILE SIZE

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

Use a small sed script to canonicalize the device names.
|
| |
|
|
|
|
|

Hard-coding it breaks virtio-scsi because the devices are called
/dev/sda etc.

This commit adds a tests/xml directory, and an LD_PRELOAD module which
can fake arbitrary libvirt XML from an external file (and is therefore
a much more flexible test than using the libvirt test:// driver
alone).
Also added is one regression test for:
https://bugzilla.redhat.com/show_bug.cgi?id=701814
Loading the given libvirt XML using Sys::Guestfs::Lib::open_guest
used to fail with the error:
format parameter is empty or contains disallowed characters at /home/rjones/d/libguestfs/perl/blib/lib/Sys/Guestfs/Lib.pm line 256.
Thanks to Tom Horsley for supplying the test data.

The two tarballs:
8252 bytes tests/data/filesanddirs-10M.tar.xz
41152 bytes tests/data/filesanddirs-100M.tar.xz
contain, as their names suggest, highly compressed files and
directories, with unpacked size respectively around 10M and 100M (the
precise size after unpacking depends on the filesystem).
These can be used for testing purposes.

Bind the easy parts of the 'btrfs' program.
The new APIs are:
btrfs-device-add: add devices to a btrfs filesystem
btrfs-device-delete: remove devices from a btrfs filesystem
btrfs-filesystem-sync: sync a btrfs filesystem
btrfs-filesystem-balance: balance a btrfs filesystem
btrfs-subvolume-create: create a btrfs snapshot
btrfs-subvolume-delete: delete a btrfs snapshot
btrfs-subvolume-list: list btrfs snapshots and subvolumes
btrfs-subvolume-set-default: set default btrfs subvolume
btrfs-subvolume-snapshot: create a writable btrfs snapshot

This means renaming various temporary files (eg. fstab.tmp) that
several of the scripts were using so they don't conflict
(eg. fstab.tmp.$$).
Also the rule:
fedora-md1.img fedora-md2.img: guest-aux/make-fedora-img.pl
causes the script to run twice in parallel when using 'make -jN'.
Replace this with a stamp file so it runs once:
fedora-md1.img fedora-md2.img: stamp-fedora-md.img
stamp-fedora-md.img: guest-aux/make-fedora-img.pl

The presumption is that all file descriptors should be created with
the close-on-exec flag set. The only exception are file descriptors
that we want passed through to exec'd subprocesses (mainly pipes and
stdin/stdout/stderr).
For open calls, we pass O_CLOEXEC as an extra flag, eg:
fd = open ("foo", O_RDONLY|O_CLOEXEC);
This is a Linux-ism, but using a macro we can easily make it portable.
For sockets, similarly:
sock = socket (..., SOCK_STREAM|SOCK_CLOEXEC, ...);
For accepted sockets, we use the Linux accept4 system call which
allows flags to be supplied, but we use the Gnulib 'accept4' module to
make this portable.
For dup, dup2, we use the Linux dup3 system call, and the Gnulib
modules 'dup3' and 'cloexec'.
