The guestfs_ll command currently lists files in the appliance if you
prefix filenames with "/..". However this is a bug, not a feature,
and we should not be testing it.

This is just code motion.

Machine-readable progress bars look like:
0/100
1/100
2/100
|
| |
|
|
|
|
|
|
| |
There are two benefits:
- the progress bars look better
- there is a reasonably accurate estimate of how long each operation
will take

This event is generated whenever a libguestfs function is called.

This library could now be called from other virt tools.

We partitioned the disk, and then tried to create a PV on the whole
disk. LVM gave the error:
Device /dev/vda not found (or ignored by filtering).
It is unclear how this bug persisted for so long. It might be due to
a change in LVM.

msg_flags was not being initialized and would have been passed to
sendmsg with a random value.

pclose can return > 0 when the status of the command was non-zero.
|
| |
|
|
|
| |
Note that errno is probably not set to a useful value here, so there
is not much point recording it.
|
| |
|
|
| |
In particular pclose returns a status > 0 if the command fails.

This refactors the code in test_qemu slightly to ensure that
FILE *fp is not leaked on error paths.

errno is pretty much random on the error path back from guestfs_launch
so there is nothing useful to be gained by checking it.
We could do with a better way to detect if appliance launch failed.
|
| |
|
|
| |
We expect guestfs_launch to fail in this program.

Remove the old top-level autobuild.sh that confused a lot
of people.
Add an autobuild.sh script that builds from the latest tarball.

Intended use in Fedora and RHEL is to encode the release
string, eg.
./configure [...] --with-extra="-%{release}"

There is another case where downloads of small files could fail if the
library side (writer) fails. In this case the library would send back
a cancellation, but it would be received after the daemon had finished
sending the whole file (because the file is small enough). The daemon
would reenter the main loop and immediately get an unexpected cancel
message, causing the daemon to die.
This commit also makes test-cancellation-download-librarycancels.sh
more robust. We use Monte-Carlo testing with a range of file sizes.
Small file sizes should trigger the error case.

The default event handler in libguestfs was simply writing all debug
output directly to stderr. However if the output contains
non-printable characters such as terminal control codes then these
would also be sent directly.
With newer SeaBIOS there is a lame attempt to implement a splash
screen using terminal control codes, thus when libguestfs tries to
display debugging output it would cause the screen to clear and debug
output to be lost.
This commit causes all non-printing characters to be escaped.
(\n and \r characters from the appliance are treated somewhat
specially).
Furthermore, instead of using write(2), use buffered stderr calls.

This function was used to print the qemu and
febootstrap-supermin-helper command lines.
Unfortunately in the qemu case it was used incorrectly: it called the
internal debug function (ie. event API callback) from the forked qemu
subprocess, which meant that higher level event callbacks might have
been invoked from the child process.
To fix this, convert the qemu case into a new function called
print_qemu_command line which just prints the command line directly to
stderr. This is called after stderr has been redirected into the pipe
to the main process. Thus the qemu command line will be marshalled
into the event API along with other qemu and appliance output.
After fixing this, only one use of guestfs___print_timestamped_argv
remained, for printing the febootstrap-supermin-helper command line.
This is converted to a local function print_febootstrap_command_line.
Also print_febootstrap_command_line is now called before we fork
febootstrap-supermin-helper, so that messages no longer overlap.

./run can now be run in a separate build directory. Since some files
needed in the image checks are found in the source tree (but not the
build tree), the source tree location is passed to make-*-img.sh via
an environment variable.

$(srcdir) is not needed for guestfs_c.c.
*.mli only exists in $(srcdir) and isn't found on "make install" otherwise
