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!
A few notes:
* The `echo hi` is needed to make sure that a file that can be read by
`nix log` is properly created (i.e. some output is needed). This is
known and to be fixed in #6051.
* We explicitly ignore the floating-CA case here: the `$out` of `input3`
depends on `$out` of `input2`. This means that there are actually two
derivations - I assume that this is because at eval time (i.e.
`nix-instantiate -A`) the hash of `input2` isn't known yet and the
other .drv is created as soon as `input2` was built. This is another
issue on its own, so we ignore the case here explicitly.
