Polling every 1 second means that even the simplest test takes at least
2 seconds. We can reasonably poll 1/10 of that to make things much
quicker (esp. given that most of the time 0.1s is enough for the
daemon to be started or stopped)
The tests are scheduled in the order they appear, so running the long
ones first slightly improves the scheduling.
On my machine, this decreases the time of `make install` from 40s to 36s
Same as 1fd127a068, but applied to a
code path (volume_pass_works -> verify_volume_pass) that the reporting
user didn't hit and wasn't able to trigger manually. I am not certain
but I suspect it will be easier to add prophylactically than to debug
if its absence causes trouble some day.
The multi-user installation on macOS, which is now the only option, has
gotten complicated enough that it discourages some users from checking
Nix out for fear of being left with a "dirty" system. Detailed
uninstallation instructions should make this less of an issue.
While trying to figure out how `nix-env`/`nix profile` work I had a hard
time understand how man pages were being installed.
Took me quite some time to figure this out, thought it might be useful
to others too!
diff-index operates on the view that git has of the working tree,
which might be outdated. The higher-level diff command does this
automatically. This change also adds handling for submodules.
fixes#4140
Alternative fixes would be invoking update-index before diff-index or
matching more closely what require_clean_work_tree from git-sh-setup.sh
does, but both those options make it more difficult to reason about
correctness.
The .git/refs/heads directory might be empty for a valid
usable git repository. This often happens in CI environments,
which might only fetch commits, not branches.
Therefore instead we let git itself check if HEAD points to
something that looks like a commit.
fixes#5302
Fixes#6122, which reports a problem with trying to run the installer
under another user (probably: user is not the disk "owner" and thus
can't mount the volume).
This also makes sure that we get the Docker images from the same Hydra
eval, rather than the latest build from job/nix/.../dockerImage, which
may not be the same.
