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.
This avoids a possible surprise if the user is using `nixpkgs.system`
and `nesting.children`. `nesting.children` is expected to ignore all
parent configuration so we shouldn't propagate the user-facing option
`nixpkgs.system`. To avoid doing so, we introduce a new internal
option for holding the value passed to eval-config.nix, and use that
when recursing for nesting.
Most VM tests have been migrated to use the python test driver
(introduced in #71684), the migration is tracked in #72828 (which also
thankfully uncovered and fixed many currently broken tests)
While increasing the acceptance and adoption of NixOS integration tests
by using a more popular language, there was also nobody willing to do
larger refactors in the currently very convoluted test infrastructure.
We plan to remove the perl infrastructure between the 20.03 and 20.09
release, to be able to do these refactorings.
Some people might be using Perl tests in their internal CI, so print a
warning for 20.03, and give users time to move to the python testing
infrastructure.
According to https://repology.org/repository/nix_unstable/problems, we have a
lot of packages that have http links that redirect to https as their homepage.
This commit updates all these packages to use the https links as their
homepage.
The following script was used to make these updates:
```
curl https://repology.org/api/v1/repository/nix_unstable/problems \
| jq '.[] | .problem' -r \
| rg 'Homepage link "(.+)" is a permanent redirect to "(.+)" and should be updated' --replace 's@$1@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
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.
While it's a good idea to automate the linting of the python code used
for our tests, I think that it can be quite distracting when hacking on
a NixOS test.
I figured that it might be more convenient to add an option as a
shortcut for this to avoid that everyone needs to dig into the test
driver again.
The upstream session files display managers use have no concept of sessions being composed from
desktop manager and window manager. To be able to set upstream session files as default
session, we need a single option. Having two different ways to set default session would be confusing,
though, so we decided to deprecate the old method.
We also created separate script for each session, just like we already had a separate desktop
file for each one, and started using displayManager.sessionPackages mechanism to make the
session handling more uniform.
