When a variable is assigned in the REPL, make sure to remove any possible reference to the old one so that we correctly pick the new one afterwards Fix #5706

This prevents Nix from barfing when run in a container where it doesn't have the appropriate privileges.

This makes nixosModule appears as a "NixOS Module" like nixosModules does.
2021-11-08Unshare mount namespace in main()Eelco Dolstra
Doing it as a side-effect of calling LocalStore::makeStoreWritable() is very ugly. Also, make sure that stopping the progress bar joins the update thread, otherwise that thread should be unshared as well.

Fix `nix repl`’s building of CA derivations
2021-11-05Fix `nix repl`’s building of CA derivationsregnat
When running a `:b` command in the repl, after building the derivations query the store for its outputs rather than just assuming that they are known in the derivation itself (which isn’t true for CA derivations) Fix #5328

Resolves #4416.
2021-10-26Make experimental-features a proper typeregnat
Rather than having them plain strings scattered through the whole codebase, create an enum containing all the known experimental features. This means that - Nix can now `warn` when an unkwown experimental feature is passed (making it much nicer to spot typos and spot deprecated features) - It’s now easy to remove a feature altogether (once the feature isn’t experimental anymore or is dropped) by just removing the field for the enum and letting the compiler point us to all the now invalid usages of it.
2021-10-25toJSON: report error position for fancier outputShay Bergmann
Given flake: ```nix { description = "nix json error provenance"; inputs = {}; outputs = { self }: { jsonFunction = _: "function"; json = builtins.toJSON (_: "function"); }; } ``` - Before: ```console ❯ nix eval --json .#jsonFunction error: cannot convert a function to JSON ``` - After: ```console ❯ nix eval --json .#jsonFunction error: cannot convert a function to JSON at /nix/store/b7imf1c2j4jnkg3ys7fsfbj02s5j0i4f-source/testflake/flake.nix:4:5: 3| outputs = { self }: { 4| jsonFunction = _: "function"; | ^ 5| json = builtins.toJSON (_: "function"); ```

Fixes #5356. This is a bit risky due to interrupts, but we have to deal with those anyway (#5353).

2021-10-07nix repl: properly deal with interruptionsMaximilian Bosch
When I stop a download with Ctrl-C in a `nix repl` of a flake, the REPL refuses to do any other downloads: nix-repl> builtins.getFlake "nix-serve" [0.0 MiB DL] downloading 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca41 error: download of 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca416e5a9415d4972b0f0' was interrupted [0.0 MiB DL] nix-repl> builtins.getFlake "nix-serve" error: interrupted by the user [0.0 MiB DL] To fix this issue, two changes were necessary: * Reset the global `_isInterrupted` variable: only because a single operation was aborted, it should still be possible to continue the session. * Recreate a `fileTransfer`-instance if the current one was shut down by an abort.
2021-10-07Refactoring: Add allowPath() methodEelco Dolstra
2021-10-06libexpr: remove matchAttrs boolean from ExprLambdaAndreas Rammhold
The boolean is only used to determine if the formals are set to a non-null pointer in all our cases. We can get rid of that allocation and instead just compare the pointer value with NULL. Saving up to sizeof(bool) + platform specific alignment per ExprLambda instace. Probably not a lot of memory but perhaps a few kilobyte with nixpkgs? This also gets rid of a potential issue with dereferencing formals based on the value of the boolean that didn't have to be aligned with the formals pointer but was in all our cases.

2021-09-30`std::visit` by referenceJohn Ericson
I had started the trend of doing `std::visit` by value (because a type error once mislead me into thinking that was the only form that existed). While the optomizer in principle should be able to deal with extra coppying or extra indirection once the lambdas inlined, sticking with by reference is the conventional default. I hope this might even improve performance.
