2023-06-19Clean up a few things related to profiles (#8526)John Ericson
- Greatly expand API docs - Clean up code in misc ways - Instead of a complicated single loop on generations, do different operations in successive subsequent steps. - Avoid `ref` in one place where `&` is fine - Just return path instead of mutating an argument in `makeName` Co-authored-by: Valentin Gagarin <valentin.gagarin@tweag.io>
2023-04-07Finish converting existing comments for internal API docs (#8146)John Ericson
* Finish converting existing comments for internal API docs 99% of this was just reformatting existing comments. Only two exceptions: - Expanded upon `BuildResult::status` compat note - Split up file-level `symbol-table.hh` doc comments to get per-definition docs Also fixed a few whitespace goofs, turning leading tabs to spaces and removing trailing spaces. Picking up from #8133 * Fix two things from comments * Use triple-backtick not indent for `dumpPath` * Convert GNU-style `\`..'` quotes to markdown style in API docs This will render correctly.
2023-03-31Ensure all headers have `#pragma once` and are in API docsJohn Ericson
`///@file` makes them show up in the internal API dos. A tiny few were missing `#pragma once`.
2023-03-27Make some comments in profiles.hh doxygen-enabledThéophane Hufschmitt
These are proper documentation of the API, so they deserve to be here
2023-03-23Factor out the generation of the profile/channel directoryThéophane Hufschmitt
Make sure that all the code paths use the same one, and that the backwards-compatibility measures are probably in place when needed
2023-02-10A setting to follow XDG Base Directory standardAlexander Bantyev
XDG Base Directory is a standard for locations for storing various files. Nix has a few files which seem to fit in the standard, but currently use a custom location directly in the user's ~, polluting it: - ~/.nix-profile - ~/.nix-defexpr - ~/.nix-channels This commit adds a config option (use-xdg-base-directories) to follow the XDG spec and instead use the following locations: - $XDG_STATE_HOME/nix/profile - $XDG_STATE_HOME/nix/defexpr - $XDG_STATE_HOME/nix/channels If $XDG_STATE_HOME is not set, it is assumed to be ~/.local/state.

2023-01-17Move the default profiles to the user’s homeThéophane Hufschmitt
Rather than using `/nix/var/nix/{profiles,gcroots}/per-user/`, put the user profiles and gcroots under `$XDG_DATA_DIR/nix/{profiles,gcroots}`. This means that the daemon no longer needs to manage these paths itself (they are fully handled client-side). In particular, it doesn’t have to `chown` them anymore (removing one need for root). This does change the layout of the gc-roots created by nix-env, and is likely to break some stuff, so I’m not sure how to properly handle that.

Also use std::string_view in a few more places.

2016-02-04StoreAPI -> StoreEelco Dolstra
Calling a class an API is a bit redundant...
2016-02-04Eliminate the "store" global variableEelco Dolstra
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)

Also, make sure --delete-older-than doesn't delete the current generation.
