synopsis: restore backwards-compatibility of `builtins.fetchGit` with Nix 2.3

|

|
||||
Compatibility with `builtins.fetchGit` from Nix 2.3 has been restored as follows:
|
||||
|
||||
* Until now, each `ref` was prefixed with `refs/heads` unless it starts with `refs/` itself.
|
||||
|
||||
Now, this is not done if the `ref` looks like a commit hash.
|
||||
|
||||
* Specifying `builtins.fetchGit { ref = "a-tag"; /* … */ }` was broken because `refs/heads` was appended.
|
||||
|
||||
Now, the fetcher doesn't turn a ref into `refs/heads/ref`, but into `refs/*/ref`. That way,
|
||||
the value in `ref` can be either a tag or a branch.
|
||||
|
||||
* The ref resolution happens the same way as in git:
|
||||
|
||||
* If `refs/ref` exists, it's used.
|
||||
* If a tag `refs/tags/ref` exists, it's used.
|
||||
* If a branch `refs/heads/ref` exists, it's used.

synopsis: Removing the `.` default argument passed to the `nix fmt` formatter

The underlying formatter no longer receives the ". " default argument when `nix fmt` is called with no arguments.
|
||||
|
||||
This change was necessary as the formatter wasn't able to distinguish between
|
||||
a user wanting to format the current folder with `nix fmt .` or the generic
|
||||
`nix fmt`.
|
||||
|
||||
The default behaviour is now the responsibility of the formatter itself, and
|
||||
allows tools such as treefmt to format the whole tree instead of only the
|
||||
current directory and below.
|
||||
|
||||
This may cause issues with some formatters: nixfmt, nixpkgs-fmt and alejandra currently format stdin when no arguments are passed.
|
||||
|
||||
Here is a small wrapper example that will restore the previous behaviour for such a formatter:
|
||||
|
||||
```nix
|
||||
{
|
||||
outputs = { self, nixpkgs, systems }:
|
||||
let
|
||||
eachSystem = nixpkgs.lib.genAttrs (import systems) (system: nixpkgs.legacyPackages.${system});
|
||||
in
|
||||
{
|
||||
formatter = eachSystem (pkgs:
|
||||
pkgs.writeShellScriptBin "formatter" ''
|
||||
if [[ $# = 0 ]]; set -- .; fi
|
||||
exec "${pkgs.nixfmt-rfc-style}/bin/nixfmt "$@"
|
||||
'');
|
||||
};

Support for building Lix with [`readline`][readline] instead of
|
||||
[`editline`][editline] has been removed. `readline` support hasn't worked for a
|
||||
long time (attempting to use it would lead to build errors) and would make Lix
|
||||
subject to the GPL if it did work. In the future, we're hoping to replace
|
||||
`editline` with [`rustyline`][rustyline] for improved ergonomics in the `nix
|
||||
repl`.

Lix, being a C++ program, can crash in a few kinds of ways.
|
||||
It can obviously do a memory access violation, which will generate a core dump and thus be relatively debuggable.
|
||||
But, worse, it could throw an unhandled exception, and, in the past, we would just show the message but not where it comes from, in spite of this always being a bug, since we expect all such errors to be translated to a Lix specific error.
|
||||
Now the latter kind of bug should print reporting instructions, a rudimentary stack trace and (depending on system configuration) generate a core dump.
|
||||
|
||||
Sample output:
|
||||
|
||||
```
|
||||
Lix crashed. This is a bug. We would appreciate if you report it along with what caused it at https://git.lix.systems/lix-project/lix/issues with the following information included:

Previously `<nix/fetchurl.nix>` did not do TLS verification. This was because the Nix sandbox in the past did not have access to TLS certificates, and Nix checks the hash of the fetched file anyway. However, this can expose authentication data from `netrc` and URLs to man-in-the-middle attackers. In addition, Nix now in some cases (such as when using impure derivations) does *not* check the hash. Therefore we have now enabled TLS verification. This means that downloads by `<nix/fetchurl.nix>` will now fail if you're fetching from a HTTPS server that does not have a valid certificate.
|
||||
|
||||
`<nix/fetchurl.nix>` is also known as the builtin derivation builder `builtin:fetchurl`. It's not to be confused with the evaluation-time function `builtins.fetchurl`, which was not affected by this issue.

|

* Note [NAR restoration security]:

* It's *critical* that NAR restoration will never overwrite anything even if

* duplicate filenames are passed in. It is inevitable that not all NARs are
|
||||
* fit to actually successfully restore to the target filesystem; errors may
|
||||
* occur due to collisions, and this *must* cause the NAR to be rejected.
|
||||
*
|
||||
* Although the filenames are blocked from being *the same bytes* by a higher
|
||||
* layer, filesystems have other ideas on every platform:
|
||||
* - The store may be on a case-insensitive filesystem like APFS, ext4 with
|
||||
* casefold directories, zfs with casesensitivity=insensitive
|
||||
* - The store may be on a Unicode normalizing (or normalization-insensitive)
|
||||
* filesystem like APFS (where files are looked up by
|
||||
* hash(normalize(fname))), HFS+ (where file names are always normalized to
|
||||
* approximately NFD), or zfs with normalization=formC, etc.
|
||||
*
|
||||
* It is impossible to know the version of Unicode being used by the underlying
|
||||
* filesystem, thus it is *impossible* to stop these collisions.
|
||||
*
|
||||
* Overwriting files as a result of invalid NARs will cause a security bug like
