This commit adds a test covering the discrepancy between parseDrvName's
implementation and documentation (the discrepancy was eliminated in the previous
commit).
The documentation for `parseDrvName` does not agree with the implementation when
the derivation name contains a dash which is followed by something that is
neither a letter nor a digit. This commit corrects the documentation to agree
with the implementation.
Previously the MANPATH was set even if MANPATH was empty beforehand
which resulted in a MANPATH of only ~/.nix-profile/share/man which
omitted the default man page directory (commonly /opt/local/share/man)
from man page results.
If we don't have any github token, we won't be able to fetch private
repos, but we are also more likely to run into API limits since
we don't have a token. To mitigate this only ever use the github api
if we actually have a token.
Older versions of Fish (such as those bundled with Ubuntu LTS 22.04) do
not support return outside of functions. We need to use the equivalent
exit instead.
The current definition of `intersectAttrs` is incorrect:
> Return a set consisting of the attributes in the set e2 that also exist in the
> set e1.
Recall that (Nix manual, section 5.1):
> An attribute set is a collection of name-value-pairs (called attributes)
According to the existing description of `intersectAttrs`, the following should
evaluate to the empty set, since no key-value *pair* (i.e. attribute) exists in
both sets:
```
builtins.intersectAttrs { x=3; } {x="foo";}
```
And yet:
```
nix-repl> builtins.intersectAttrs { x=3; } {x="foo";}
{ x = "foo"; }
```
Clearly the intent here was for the *names* of the resulting attribute set to be
the intersection of the *names* of the two arguments, and for the values of the
resulting attribute set to be the values from the second argument.
This commit corrects the definition, making it match the implementation and intent.
Make sure that people who run Nix in non-interactive mode (and so don't have the possibility to interactively accept the individual flake configuration settings) are aware of this flag.
Fix#7086
These settings seem harmless, they control the same polling
functionality that timeout does, but with different behavior. Should
be safe for untrusted users to pass in.
I just had a colleague get confused by the previous phrase for good
reason. "valid" sounds like an *objective* criterion, e.g. and *invalid
signature* would be one that would be trusted by no one, e.g. because it
misformatted or something.
What is actually going is that there might be a signature which is
perfectly valid to *someone else*, but not to the user, because they
don't trust the corresponding public key. This is a *subjective*
criterion, because it depends on the arbitrary and personal choice of
which public keys to trust.
I therefore think "trustworthy" is a better adjective to use. Whether
something is worthy of trust is clearly subjective, and then "trust"
within that word nicely evokes `trusted-public-keys` and friends.
The history is not critical to the functionality of nix repl, so it's
enough to warn here, rather than refuse to start if the directory Nix
thinks the history should live in can't be created.
