libguestfs has used double and triple underscores in identifiers.
These aren't valid for global names in C++.
The first step is to replace all guestfs___* (3 underscores) with
guestfs_int_*. We've used guestfs_int_* elsewhere already as a prefix
for internal identifiers.
This is an entirely mechanical change done using:
git ls-files | xargs perl -pi.bak -e 's/guestfs___/guestfs_int_/g'

The gnulib 'error' module uses 'program_name'. On some platforms --
but not Linux / glibc -- it references it as:
extern char *program_name;
This means when you compile libguestfs on non-glibc (eg. Mac OS X)
gnulib requires 'program_name' as an external string reference, which
we don't provide.
This change doesn't define this string reference for gnulib, but it
does change the name of the macro we use to avoid conflicts if we
eventually need to export 'program_name' as a string.

test-dlopen needs to be added only when libdl is available, and it is
like that already (within if HAVE_LIBDL); hence don't unconditionally
add it as well.
Commit 96158d42f5 enabled the previously
private guestfs_add_libvirt_dom API. It also tried to enable the
existing test for this API, but failed to do that correctly. Also the
test was broken. Fix all of this.
This fixes commit 96158d42f5.
This API already existed (as guestfs___add_libvirt_dom), and was used
by a few tools.
This commit changes it to a public API.
Note that for reasons outlined in the previous commit message, it is
impossible to call this from guestfish or from non-C language
bindings.
md5sum(1) does not exist everywhere, so wrap it in an own function so
the right implementation can be chosen on each OS. Also, wrapping it
avoid using awk everytime.
get_current_dir_name exists on GNU libc only, so not portable.
On the other hand, while POSIX leaves a null buffer argument for getcwd
as unspecified behaviour, basically the most used/important Unix
implementations (GNU libc, FreeBSD's libc, etc) allow such value,
returning a new allocated buffer with the current directory.
In any case, the change just affects two tests, so even if it hits a
libc not implementing this behaviour for getcwd, only tests are
affected.
Add a IfNotCrossAppliance prereq for tests, so a test using it can only
be run when the appliance is a copy of the running host system; this can
help marking tests which run stuff (usually built in the host) inside
the appliance.
This file causes the test ISO to be rebuilt every time.
Instead of including it as a Makefile dependency, create it just
before making the ISO, which has the same effect.
A test in fish/ also used this file. Change it so it doesn't need it.
Add support for aarch64 to the file_architecture API, so we can
detect aarch64 guests correctly.
Add a test binary and library. These were generated on an aarch64
machine by doing:
echo 'main(){}' > bin.c
gcc bin.c -o bin-aarch64-dynamic
strip --strip-all bin-aarch64-dynamic
echo '' > lib.c
gcc -shared lib.c -o lib-aarch64.so
strip --strip-all lib-aarch64.so
All tests run under the ./run binary. For a long time the ./run
binary has set the $PATH environment variable to contain all of the
directories with binaries in them.
Therefore there is no reason to use ../fish/guestfish instead of just
plain guestfish (and the same applies to other built binaries).
The default charset for these filesystems depends on how the kernel was
configured with, so explicitly set the default one (as specified in
Linux sources), eventually setting later a new one for the tests.
This was based an incorrect translation of what the old virt-v2v was
doing. %systemroot%\Drivers is not expected to exist already, and
indeed does not exist in a real Windows 7 guest.
Fix the Name and Packages database so it looks enough like a modern
RPM database to fool inspection. I'm not sure whether or not the old
version ever worked, but it doesn't work now.
The format is not documented, but in brief:
The Name database contains (Name, link) pairs. The link is an
arbitrary 32 bit integer.
The Packages database contains (link, RPM-blob) pairs.
The RPM-blob is a binary blob formatted like this:
* Number of fields 4 bytes, big endian
* Size in bytes of the store 4 bytes, big endian
* Field descriptions:
list of (RPMTAG, 0, offset in store, 0)
4 * 4 * nr_fields bytes, big endian
* The store binary data containing ASCIIZ strings
For the values of RPMTAG_* that we understand, see src/inspect-apps.c.
Move the minimum memory check from the environment parsing to
set_memsize, so the limit is actually enforced also when using the API.
Adapt the rhbz557655.sh test to the invalid memsize values being
rejected now, and add a new test for checking invalid parameters
explicitly.
This is useful when analysing with `perf' since it allows us to
increase the amount of time in the test versus the amount of time
spent starting the appliance.
This test worked by uploading a 100MB file into a 100MB container and
seeing the inevitable crash. Unfortunately virtio-mmio (used on
aarch64) is quite slow. Since this test is not testing the speed of
virtio-mmio, use a smaller test file so the test finishes in a
reasonable time.
For example:
$ time ./run ./tests/qemu/qemu-boot -n 100
real 1m19.794s
user 0m10.001s
sys 0m5.928s
will run 100 appliance start/stops, from multiple threads.
This test has not been run since 2012 as it depends on specifics of
how supermin and new-style appliances work (see
commit 2d89aef897).
This commit removes the test entirely.
