Rename ReadOnly to Immutable and clarify its purpose. 2023-05-17 09:04:48 +01:00

Need to open database using immutable parameter.
This requires switching on SQLITE_OPEN_URI because there is no open flag to
make the database immutable. Without immutable, sqlite will still attempt to
create journal and wal files, even when the database is opened read-only.

https://www.sqlite.org/c3ref/open.html

The immutable parameter is a boolean query parameter that indicates that the
database file is stored on read-only media. When immutable is set, SQLite
assumes that the database file cannot be changed, even by a process with higher
privilege, and so the database is opened read-only and all locking and change
detection is disabled.

e997512523 Fix the printing of the installables on nix profile install conflict
- If the element comes from a flake, print the full flakeref (with the
  fragment part) and not just the reference to the flake itself
- If the element doesn't come from a flake, print its store path(s)

This is a bit too verbose, but has the advantages of being correct (and
not crashing), so it's strictly better than the previous situation

Reword info on XDG base dirs (#8338)
This gives some more context and should clarify why it works that way.
Also link it from the section on `NIX_USER_CONF_FILES`.

98afd6ff76 Delete commited build artifacts
They were improperly added in 8a93b5a551.

They were not `.gitignore`d because they were stale in that commit --
build artifacts no longer used that name by then and so `.gitignore` was
updated accordingly.

bbd7d5de09 Fix some bounds in rapid check instances
`inRange` is exclusive not inclusive:
https://github.com/emil-e/rapidcheck/blob/master/doc/generators.md#usage

Furthermore, use `std::variant_size_v` so we use the right number
automatically.

Finally, make the `switch` assert the discriminant is in bounds as
expected.

f7c896cfd8 Dedup some markdown -> C++ big literal stuff in build system
This pattern rule was unwisely hidden in `src/libstore/local.mk`. Now it
is properly in `mk/` and we reuse it for the profile docs too.

Merge pull request #7601 from obsidiansystems/string-installables
Make more string values work as installables
2023-05-15 15:42:57 +02:00

d2162e7acd Make more string values work as installables
As discussed in #7417, it would be good to make more string values work
as installables. That is to say, if an installable refers to a value,
and the value is a string, it used to not work at all, since #7484, it
works somewhat, and this PR make it work some more.

The new cases that are added for `BuiltPath` contexts:

- Fixed input- or content-addressed derivation:

  ```
  nix-repl> hello.out.outPath
  "/nix/store/jppfl2bp1zhx8sgs2mgifmsx6dv16mv2-hello-2.12"

  nix-repl> :p builtins.getContext hello.out.outPath
  { "/nix/store/c7jrxqjhdda93lhbkanqfs07x2bzazbm-hello-2.12.drv" = { outputs = [ "out" ]; }; }

  The string matches the specified single output of that derivation, so
  it should also be valid.

- Floating content-addressed derivation:

  ```
  nix-repl> (hello.overrideAttrs (_: { __contentAddressed = true; })).out.outPath
  "/1a08j26xqc0zm8agps8anxpjji410yvsx4pcgyn4bfan1ddkx2g0"

  nix-repl> :p builtins.getContext (hello.overrideAttrs (_: { __contentAddressed = true; })).out.outPath
  { "/nix/store/qc645pyf9wl37c6qvqzaqkwsm1gp48al-hello-2.12.drv" = { outputs = [ "out" ]; }; }
  ```

  The string is not a path but a placeholder, however it also matches
  the context, and because it is a CA derivation we have no better
  option. This should also be valid.

We may also want to think about richer attrset based values (also
discussed in that issue and #6507), but this change "completes" our
string-based building blocks, from which the others can be desugared
into or at least described/document/taught in terms of.

Progress towards #7417
