The test harness provides the commands it wishes to run in Bourne
syntax. This fails if the user uses a different shell. For example,
with fish:
machine.wait_for_unit("graphical-session.target", "alice")
machine # fish: Unsupported use of '='. To run '-u`' with a modified environment, please use 'env XDG_RUNTIME_DIR=/run/user/`id -u`…'
machine # XDG_RUNTIME_DIR=/run/user/`id -u` systemctl --user --no-pager show "graphical-session.target"
machine # ^
machine # [ 16.329957] su[1077]: pam_unix(su:session): session closed for user alice
error: retrieving systemctl info for unit "graphical-session.target" under user "alice" failed with exit code 127
This completes the removal of the nested log feature, which previously
got removed from Nix, Hydra, stdenv and GNU Make. In particular, this
means that the output of VM builds no longer contains a copy of
jQuery.
If a program (e.g. nixos-install) writes more than 1000 lines to
stderr during execute(), then process_serial_output() deadlocks
waiting for the queue to be processed. So use an unbounded queue
instead.
We should probably get rid of the structured log output (log.xml),
since then we don't need the log queue anymore.
The docstring says it uses a directory shared among all vms, although
that doesn't seem necessary for the functionality. However, it does need
to be consistent between the guest and host.
The codec format 'unicode_escape' was introduced in 52ee102 to handle
undecodable bytes in boot menus.
This made the problem worse as unicode chars outside of iso-8859-1
produce garbled output and valid utf-8 strings (such as "\x" ) trigger
decoding errors.
Fix this by using the default 'utf-8' codec and by explicitly ignoring
decoding errors.
This changes the python test driver to match the behavior of the perl
test driver. I.e. the directory mounted into /tmp/shared should be the
same for all machines.
This probably fixes many tests, but I found this while investigating
failures in nixos/tests/ceph-multi-node.nix.
we previously immediately returned the first commands output, and didn't
execute any of the other commands.
Now, return the last commands output.
This should be documented in the method docstring.
Condition seems to be inverted. Crash and shutdown only make sense, when
the machine is booted; i.e. we return immediately otherwise.
In the Perl test driver this is:
return unless $self->{booted};
When IPXE tests were added, an option was added for configuring only
the frontend, and the backend configuration was dropped entirely. This
caused most installer tests to fail.
See #49441 for an earlier attempt, which was subsequently reverted. I am
assuming that doubling the time will be sufficient if the machine is
overloaded since so many of the tests already pass at 5 minutes, while
still not holding back failures for needlessly long.
