Valentin Gagarin a556143dc1 add objectives and tasks for Nix team
so far there were no even remotely measurable objectives, only a general
purpose statement.

this change is intended to focus the team's work on what I (and many
others I talked to) perceive to be the main pain point in the
development process.

Clean up daemon handling in the tests
2023-02-23 18:13:14 +01:00
John Ericson 87da941348 Clean up daemon handling
Split `common.sh` into the vars and functions definitions vs starting
the daemon (and possibly other initialization logic). This way,
`init.sh` can just `source` the former. Trying to start the daemon
before `nix.conf` is written will fail because `nix daemon` requires
`--experimental-features 'nix-command'`.

`killDaemon` is idempotent, so it's safe to call when no daemon is
running.

`startDaemon` and `killDaemon` use the PID (which is now exported to
subshells) to decide whether there is work to be done, rather than
`NIX_REMOTE`, which might conceivably be set differently even if a
daemon is running.

`startDaemon` and `killDaemon` can save/restore the old `NIX_REMOTE` as
`NIX_REMOTE_OLD`.

`init.sh` kills daemon before deleting everything (including the daemon
socket).

John Ericson 5dbbf23332 Make init.sh safe to run twice
`init.sh` is tested on its own. We used to do that. I deleted it in
4720853129 but I am not sure why. Better
to just restore it; at one point working on this every other test
passed, so seems good to check whether `init.sh` can be run twice.

We don't *need* to run `init.sh` twice, but I want to try to make our
tests as robust as possible so that manual debugging (where tests for
better or worse might be run ways that we didn't expect) is less
fragile.

error message in Hydra (https://hydra.nixos.org/build/210121811).

Fix `isStatic` arguments to `commonDeps`

John Ericson 16111aa32e Fix isStatic arguments to commonDeps
Some dependencies supposed to be skipped in the cross build, along with
not using the gold linker. But in https://github.com/NixOS/nix/pull/6538
this was accidentally not preserved.

Also since https://github.com/NixOS/nix/pull/6538 we saw some new
aarch64-linux static build failures. This is a first attempt to try to
fix those failures. If this is not sufficient, there are other things we
can try next.

It is independent of SourceExprCommand, which is about parsing
installables, except for the fact that parsing installables is one of
the many things influenced by read-only mode.

Nix's own flake: Dedup and memoize more
- `nixpkgsFor` does all of native, static, cross, and the different stdenvs.

- The main Nix derivation is no longer duplicated for static.

- DRY nixpkgs.lib and lib.genAttrs calls.

We are looking for *$ because it indicate that it was constructed with a new but
not release. De-referencing shallow copy so deleting as whole might create
dangling pointer that's why we move it so we delete a empty containers + the
nice perf boost.

Eelco Dolstra 35049389cd Fix static build
For static builds, we need to propagate all the static library
dependencies to the link of the program. E.g. if libstore-tests-exe
depends on libnixstore-tests, and libnixstore-tests depends on
libstore, then libstore-tests-exe needs to link against libstore.

Improve hacking.md
- Refer to current version in readme
- Split into flakes and non-flakes section
- Change order to move nix-build to the end, since people often start
  with it in the beginning.
- Use proper "Note" syntax
- Add notes about editor integration
- Move information about target platforms and stdenvs into separate
  sections

John Ericson 55016b6fcd Test nix build --json return output paths in floating CA case
Adding a test to ensure there is no regression.

The tests that are split out of `tests/build.sh` are ones that don't yet
work with CA derivation. I have not yet evaluated whether they should or
not.

This behavior, reported missing in issue #4661, already got fixed in
PR #4818, but didn't get a test case then.
