When performing OCR, some of the Tesseract settings perform better than
others on a variety of different workloads, but they mostly take
~negligible incremental time to run compared to the overhead of running
the ImageMagick filters.
After this commit, we try using all three of the current Tesseract
models (classic, LSTM, and classic+LSTM) to generate output text. This
fixes chromium-90's tests at release-20.09, and should make cases where
you're looking for *specific* text better, with the tradeoff of running
Tesseract multiple times.
To make it sensible to cherrypick this into release-20.09, this doesn't
change the existing API surface for the test driver. In particular,
get_screen_text continues to have the existing behaviour.
backends changing shouldn't be very likely, but services may well change. we
should restart sshguard from nixos-rebuild instead of merely plopping down a new
config file and waiting for the user to restart sshguard.
First because IFD (import-from-derivation) is not allowed on hydra.nixos.org,
and second because without https://github.com/NixOS/hydra/pull/825
hydra-eval-jobs crashes instead of skipping aggregated jobs which fail
(here because they required an IFD).
Rather than relying on carefully avoiding touching the 9P-mounted
/nix/store, we instead install a small NixOS system, similar to
the installer tests, and boot from that.
This avoids the various pitfalls associated with trying to unsuspend
properly and trades off a bunch of boilerplate for what will hopefully
be a more reliable test.
Additionally, this test now actually tests booting the system using a
bootloader, rather than the previous method of just booting the kernel
directly.
There is no need for a separate unit. Simplify the NixOS module by adding the shell code to preStart of the main unit, where the other initialization code already is.
Things will get quite broken if an /etc/passwd entry contains a
colon (which terminates a field), or a newline (which terminates a
record). I know because I just accidentally made a user whose home
directory path contained a newline!
So let's make sure that can't happen.
Upstream repositories do no longer exists. There has been no release in
a while. - Not a good combination for a network daemon running as root
in C that parses network packets...
