docs: fixed the default priority of nix-env --install (#8945) 2023-09-09 06:54:39 +00:00

fix: nix shell multiple commands example (#8950)
The `-c` flag belongs to `sh` not `nix shell`. As it stands, the command errors with:

```
$ nix shell nixpkgs#gnumake --command sh --command "cd src && make"
sh: --command: invalid option
```

https://github.com/NixOS/nix/pull/8276 was good for readability, but it missed this since that PR used a find/replace script.

John Ericson 80d7994f52 Special-case error message to add extra information
The Derivation parser and old ATerm unfortunately leaves few ways to get
nice errors when an old version of Nix encounters a new version of the
format. The most likely scenario for this to occur is with a new client
making a derivation that the old daemon it is communicating with cannot
understand.

The extensions we just created for dynamic derivation deps will add a
version field, solving the problem going forward, but there is still the
issue of what to do about old versions of Nix up to now.

The solution here is to carefully catch the bad error from the daemon
that is likely to indicate this problem, and add some extra context to
it.

There is another "Ugly backwards compatibility hack" in
`remote-store.cc` that also works by transforming an error.

John Ericson 7ad66cb3ef Allow dynamic derivation deps in inputDrvs
We use the same nested map representation we used for goals, again in
order to save space. We might someday want to combine with `inputDrvs`,
by doing `V = bool` instead of `V = std::set<OutputName>`, but we are
not doing that yet for sake of a smaller diff.

The ATerm format for Derivations also needs to be extended, in addition
to the in-memory format. To accomodate this, we added a new basic
versioning scheme, so old versions of Nix will get nice errors. (And
going forward, if the ATerm format changes again the errors will be even
better.)

`parsedStrings`, an internal function used as part of parsing
derivations in A-Term format, used to consume the final `]` but expect
the initial `[` to already be consumed. This made for what looked like
unbalanced brackets at callsites, which was confusing. Now it consumes
both which is hopefully less confusing.

As part of testing, we also created a unit test for the A-Term format for
regular non-experimental derivations too.

John Ericson b7edc2099f Improve derivation parsing
- Don't assert: Derivation ATerms are not necessarily produced by Nix,
  and parsers should always throw graceful errors

- Improve error message from `static void except(..)`, shows both what
  we expected and what we actually got.

The intention is that we backport it, and then hopefully a few people
might get slightly better errors if they try out new experimental drv
files (for RFC 92) with an old version of Nix.

this is a pure reformatting, contents were not changed

one sentence per line makes reviewing diffs and making suggestions much
more convenient. the indentation was an artifat of the DocBook
migration.

It *should* be fine to test 23.05's other Nix versions as those

our terrible CI setup's log.
