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.
2021-10-17fetch: nicer infinite recursion errorsKevin Amado
- This change applies to builtins.fetchurl and builtins.fetchTarball - PoC: `let x = builtins.fetchurl x; in x` - Before: ```bash $ nix-instantiate --extra-experimental-features flakes --strict error: infinite recursion encountered ``` - After: ```bash $ nix-instantiate --extra-experimental-features flakes --strict error: infinite recursion encountered at /data/github/kamadorueda/nix/test.nix:1:9: 1| let x = builtins.fetchurl x; in x | ^ ``` Mentions: #3505
2021-10-17Add error reporting to machine spec paserAlexey Novikov
Currently machine specification (`/etc/nix/machine`) parser fails with a vague exception if the file had incorrect format. This commit adds verbose exceptions and unit-tests for the parser.
2021-10-17Fix error detection in 'base64Decode()'Alexey Novikov
Fixed a bug in initialization of 'base64DecodeChars' variable. Currently decoder do not fail on invalid Base64 strings. Added test-case to verify the fix. Also have made 'base64DecodeChars' to be computed at compile time. And added a test case to encode/decode string with non-printable charactes.
2021-10-15fetchTree: add pos to EvalState::forceValueKevin Amado
- This way we improve error messages on infinite recursion - Demo: ```nix let x = builtins.fetchTree { type = "git"; inherit x; }; in x ``` - Before: ```bash $ nix-instantiate --extra-experimental-features flakes --strict error: infinite recursion encountered ``` - After: ```bash $ nix-instantiate --extra-experimental-features flakes --strict error: infinite recursion encountered at /data/github/kamadorueda/nix/test.nix:3:10: 2| type = "git"; 3| inherit x; | ^ 4| }; ``` Mentions: #3505

2021-10-14pathInfoCache: Use the entire base name as the cache keyEelco Dolstra
This fixes a bug in the garbage collector where if a path /nix/store/abcd-foo is valid, but we do a isValidPath("/nix/store/abcd-foo.lock") first, then a negative entry for /nix/store/abcd is added to pathInfoCache, so /nix/store/abcd-foo is subsequently considered invalid and deleted.

(where "referrers" includes the reverse of derivation outputs and derivers). Now we do a full traversal to look if we can reach any root. If not, all paths reached can be deleted.

The garbage collector no longer blocks other processes from adding/building store paths or adding GC roots. To prevent the collector from deleting store paths just added by another process, processes need to connect to the garbage collector via a Unix domain socket to register new temporary roots.
