Enabled for fetchGit, which historically had this behavior,
among other behaviors we do not want in fetchGit.
fetchTree disables this parameter by default. It can choose the
simpler behavior, as it is still experimental.
I am not confident that the filtering implementation is future
proof. It should reuse a source filtering wrapper, which I believe
Eelco has already written, but not merged yet.
Also move `SourcePath` into `libutil`.
These changes allow `error.hh` and `error.cc` to access source path and
position information, which we can use to produce better error messages
(for example, we could consider omitting filenames when two or more
consecutive stack frames originate from the same file).
This uses `git check-ignore` to determine if files are ignored before
attempting to add them in `putFile`.
We also add a condition to the `fetchFromWorkdir` filter to always add
the `flake.lock` file, even if it's not tracked. This is necessary to
resolve inputs.
This fixes#8854 without `git add --force`.
We occasionnally commit to git repositories (like with `nix flake update --commit-lock-file`).
This shells out to `git commit`, which might wait for user input (for a signing key passphrase for instance).
Disable the progress bar while this is running to make sure that the
user can enter it.
This avoids repeated copying of the same source tree between Nix
invocations. It requires the accessor to have a "fingerprint" (e.g. a
Git revision) that uniquely determines its contents.
All OS and IO operations should be moved out, leaving only some misc
portable pure functions.
This is useful to avoid copious CPP when doing things like Windows and
Emscripten ports.
Newly exposed functions to break cycles:
- `restoreSignals`
- `updateWindowSize`
The new `MemorySourceAccessor` rather than being a slightly lossy flat
map is a complete in-memory model of file system objects.

This adds publicKeys as an optional fetcher input attribute to flakes
and builtins.fetchGit to provide a nix interface for the json-encoded
`publicKeys` attribute of the git fetcher.

This implements the git input attributes `verifyCommit`, `keytype`,
`publicKey` and `publicKeys` as experimental feature
`verified-fetches`. `publicKeys` should be a json string.
This representation was chosen because all attributes must be of type bool,
int or string so they can be included in flake uris (see definition of
fetchers::Attr).
