8614cf1334 Non-blocking garbage collector
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.

This reverts some parts of commit
8430a8f086 which was trying to rethrow
some exceptions while we weren’t in the context of a `catch` block,
causing some weird “terminate called without an active exception”
errors.

nix repl: properly deal with interruptions
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 'e9828a9e01' 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.

cae41eebff libexpr: remove matchAttrs boolean from ExprLambda
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.

c6718a9d95 Don't reset the logger in a vfork
9c766a40cb broke logging from the
daemon, because commonChildInit is called when starting the build hook
in a vfork, so it ends up resetting the parent's logger. So don't
vfork.

It might be best to get rid of vfork altogether, but that may cause
problems, e.g. when we call an external program like git from the
evaluator.

242f9bf3dc std::visit by reference
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.

libexpr: throw a more helpful eval-error if a builtin is not available due to a missing feature-flag
I found it somewhat confusing to have an error like

    error: attribute 'getFlake' missing

if the required experimental-feature (`flakes`) is not enabled. Instead,
I'd expect Nix to throw an error just like it's the case when using e.g. `nix
flake` without `flakes` being enabled.

With this change, the error looks like this:

    $ nix-instantiate -E 'builtins.getFlake "nixpkgs"'
    error: Cannot call 'builtins.getFlake' because experimental Nix feature 'flakes' is disabled. You can enable it via '--extra-experimental-features flakes'.

           at «string»:1:1:

                1| builtins.getFlake "nixpkgs"
                 | ^

I didn't use `settings.requireExperimentalFeature` here on purpose
because this doesn't contain a position. Also, it doesn't seem as if we
need to catch the error and check for the missing feature here since
this already happens at evaluation time.

build: also throw hash-mismatch errors if buildMode == bmCheck
This actually bit me quite recently in `nixpkgs` because I assumed that
`nix-build --check` would also error out if hashes don't match anymore[1]
and so I wrongly assumed that I couldn't reproduce the mismatch error.

The fix is rather simple, during the output registration a so-called
`delayedException` is instantiated e.g. if a FOD hash-mismatch occurs.
However, in case of `nix-build --check` (or `--rebuild` in case of `nix
build`), the code-path where this exception is thrown will never be
reached.

By adding that check to the if-clause that causes an early exit in case
of `bmCheck`, the issue is gone. Also added a (previously failing)
test-case to demonstrate the problem.

[1] https://github.com/NixOS/nixpkgs/pull/139238, the underlying issue
    was that `nix-prefetch-git` returns different hashes than `fetchgit`
    because the latter one fetches submodules by default.

9d67332e4b Better eval error locations for interpolation and +
Previously, type or coercion errors for string interpolation, path
interpolation, and plus expressions were always reported at the
beginning of the outer expression. This leads to confusing evaluation
error messages making it hard to accurately diagnose and then fix the
error.

For example, errors were reported as follows.

```
cannot coerce an integer to a string
1| let foo = 7; in "bar" + foo
 |                 ^

cannot add a string to an integer
1| let foo = "bar"; in 4 + foo
 |                     ^

cannot coerce an integer to a string
1| let foo = 7; in "x${foo}"
 |                  ^
```

This commit changes the ExprConcatStrings expression vector to store a
sequence of expressions *and* their expansion locations so that error
locations can be reported accurately. For interpolation, the error is
reported at the beginning of the entire `${foo}`, not at the beginning
of `foo` because I thought this was slightly clearer. The previous
errors are now reported as:

```
cannot coerce an integer to a string
1| let foo = 7; in "bar" + foo
 |                         ^

cannot add a string to an integer
1| let foo = "bar"; in 4 + foo
 |                         ^

cannot coerce an integer to a string
1| let foo = 7; in "x${foo}"
 |                   ^
```

The error is reported at this kind of precise location even for
multi-line indented strings.

This probably helps with at least some of the cases mentioned in #561

incorrectly used for another.

Alternative to #4639. You can still read flake.lock, but at least in
reproducible workflows like NixOS configurations where you require a
non-dirty tree, evaluation will fail because there is no rev.

e5596113f7 Disallow reading flake.lock
With --no-write-lock-file, it's possible that flake.lock is out of
sync with the actual inputs used by the evaluation. So doing fromJSON
(readFile ./flake.lock) will give wrong results.

0b42a0f781 preloadNSS: fixup nss_dns load
Before this commit, the dns lookup in preloadNSS would still go through
nscd. This did not have the effect of loading the nss_dns.so as expected
(nss_dns.so being out of reach from within the sandbox).

Should LOCALDOMAIN environment variable be defined, nss will completely
avoid nscd and will do its dns resolution on its own.

By temporarly setting LOCALDOMAIN variable before calling in NSS, we can
force NSS to load the shared libraries as expected.

Fixes #5089

bc6e7ca046 Don't use read-only mode for nix build --dry-run
In dry run mode, new derivations can't be create, so running the command on anything that has not been evaluated before results in an error message of the form `don't know how to build these paths (may be caused by read-only store access)`.

For comparison, the classical `nix-build --dry-run` doesn't use read-only mode.

Closes #1795

nix-store --serve: pass on settings.keepFailed from SSH store
When doing e.g.

      builders \
      'ssh://mfhydra?remote-store=/home/bosch/store x86_64-linux - 10 4 big-parallel'

this doesn't work properly because this build-setting is ignored.

I changed this behavior by passing the `settings.keepFailed` through the
serve-protocol to remote machines to make sure that I can introspect the
build-directory (which is particularly helpful when I have to look at a
`config.log` from a failed build for instance).

b2d3976163 Fix potential race-condition in reference scanning code
Previously the code ensures that the isBase32 array would only be
initialised once in a single-threaded context. If two threads happen to
call the function before the initialisation was completed both of them
would have completed the initialization step. This allowed for a
race-condition where one thread might be done with the initialization
but the other thread sets all the fields to false again. For a brief
moment the base32 detection would then produce false-negatives.

fbf42c55ac nix-shell --pure: Let it work for any derivation
`nix-shell --pure` when applied to a non stdenv derivation doesn't seem
to clear the PATH. It expects the stdenv/setup file to do so.

This adds an explicit `unset PATH` by nix-build.cc (nix-shell) itself so
that it's not reliant on stdenv/setup anymore.

This does not break impure nix-shell since the PATH is persisted as the
variable `p` prior in the bash rcfile

libutil: initialize the base64 decode array only once
Previously, despite having a boolean that tracked initialization, the
decode characters have been "calculated" every single time a base64
string was being decoded.

With this change we only initialize the decode array once in a
thread-safe manner.

d9ba3385a9 Don’t send the experimental-features to the daemon
The experimental features are, well, experimental, and shouldn’t be
carelessly and transparently enabled.
Besides, some (`ca-derivations` at least) need to be enabled at startup
in order to work properly.
So it’s better to just require that daemon be started with the right
`experimental-features` option.

fe1f34fa60 Low-latency closure copy
This adds a new store operation 'addMultipleToStore' that reads a
number of NARs and ValidPathInfos from a Source, allowing any number
of store paths to be copied in a single call. This is much faster on
high-latency links when copying a lot of small files, like .drv
closures.

For example, on a connection with an 50 ms delay:

Before:

  $ nix copy --to 'unix:///tmp/proxy-socket?root=/tmp/dest-chroot' \
    /nix/store/90jjw94xiyg5drj70whm9yll6xjj0ca9-hello-2.10.drv \
    --derivation --no-check-sigs
  real    0m57.868s
  user    0m0.103s
  sys     0m0.056s

After:

With this, we don't have to copy the entire .drv closure to the

destination store if it needs to build a derivation.

In particular, this now works:

  $ nix path-info --eval-store auto --store https://cache.nixos.org nixpkgs#hello

Previously this would fail as it would try to upload the hello .drv to
cache.nixos.org. Now the .drv is instantiated in the local store, and
then we check for the existence of the outputs in cache.nixos.org.

ad24921de8 Rename findDerivationFilename -> findPackageFilename
It does not operate on a derivation and does not return a
derivation path. Instead it works at the language level,
where a distinct term "package" is more appropriate to
distinguish the parent object of `meta.position`; an
attribute which doesn't even make it into the derivation.

of having to add --no-registries to every command, this commit allows to
set use-registries = false in the config. --no-registries is still allowed

- This can legitimately happen (for example because of a non-determinism
  causing a build-time dependency to be kept or not as a runtime

- Because of older Nix versions, it can happen that we encounter a
  realisation with an (erroneously) empty set of dependencies, in which
  case we don’t want to fail, but just warn the user and try to fix it.

7daf0c6ef1 Forward the experimental features to the nix repl subprocesses
Pass the current experimental features using `NIX_CONFIG` to the various
Nix subprocesses that `nix repl` invokes.

This is quite a hack, but having `nix repl` call Nix with a subprocess
is a hack already, so I guess that’s fine.

bf7960a4ed develop: Discard the input{Overrides,Updates} when getting bash
`nix develop` is getting bash from an (assumed existing) `nixpkgs`
flake. However, when doing so, it reuses the `lockFlags` passed to the
current flake, including the `--input-overrides` and `--input-update`
which generally don’t make sense anymore at that point (and trigger a
warning because of that)

Clear these overrides before getting the nixpkgs flake to get rid of the
warning.

Apply OS checks to host platform, not build
Previously, the build system used uname(1) output when it wanted to
check the operating system it was being built for, which meant that it
didn't take into-account cross-compilation when the build and host
operating systems were different.

To fix this, instead of consulting uname output, we consult the host
triple, specifically the third "kernel" part.

For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a
simple ifeq to test whether we're compiling for that system, but for
other platforms, like Darwin, FreeBSD, or Solaris, we have to use a
more complicated check to take into account the version numbers at the
end of the "kernel"s.  I couldn't find a way to just strip these
version numbers in GNU Make without shelling out, which would be even
more ugly IMO.  Because these checks differ between kernels, and the
patsubst ones are quite fiddly, I've added variables for each host OS
we might want to check to make them easier to reuse.

Set environment variables for .attrs.json & .attrs.sh
This way no derivation has to expect that these files are in the `cwd`
during the build. This is problematic for `nix-shell` where these files
would have to be inserted into the nix-shell's `cwd` which can become
problematic with e.g. recursive `nix-shell`.

To remain backwards-compatible, the location inside the build sandbox
will be kept, however using these files directly should be deprecated
from now on.

Source complete env in nix-shell with __structuredAttrs = true;
This is needed to push the adoption of structured attrs[1] forward. It's
now checked if a `__json` exists in the environment-map of the derivation
to be openend in a `nix-shell`.

Derivations with structured attributes enabled also make use of a file
named `.attrs.json` containing every environment variable represented as
JSON which is useful for e.g. `exportReferencesGraph`[2]. To
provide an environment similar to the build sandbox, `nix-shell` now
adds a `.attrs.json` to `cwd` (which is mostly equal to the one in the
build sandbox) and removes it using an exit hook when closing the shell.

To avoid leaking internals of the build-process to the `nix-shell`, the
entire logic to generate JSON and shell code for structured attrs was
moved into the `ParsedDerivation` class.

  $ nix build --store unix:///tmp/chroot/nix/var/nix/daemon-socket/socket?root=/tmp/chroot nixpkgs#hello

When the `keep-going` option is set to `true`, make `nix flake check`
continue as much as it can before failing.

The UI isn’t perfect as-it-is as all the lines currently start with a
mostly useless `error (ignored): error:` prefix, but I’m not sure what
the best output would be, so I’ll leave it as-it-is for the time being

(This is a bit hijacking the `keep-going` flag as it’s supposed to be a
build-time only thing. But I think it’s faire to reuse it here).

When adding a path to the local store (via `LocalStore::addToStore`),
ensure that the `ca` field of the provided `ValidPathInfo` does indeed
correspond to the content of the path.
Otherwise any untrusted user (or any binary cache) can add arbitrary
content-addressed paths to the store (as content-addressed paths don’t
need a signature).

Only link with libdl on Linux
Linux is (as far as I know) the only mainstream operating system that
requires linking with libdl for dlopen.  On BSD, libdl doesn't exist,
so on non-FreeBSD BSDs linking will currently fail.  On macOS, it's
apparently just a symlink to libSystem (macOS libc), presumably
present for compatibility with things that assume Linux.

So the right thing to do here is to only add -ldl on Linux, not to add
it for everything that isn't FreeBSD.

Matthew Bauer
3d90ab9345 Fix extra slash in canonPath output
When you have a symlink like:

  /tmp -> ./private/tmp

you need to resolve ./private/tmp relative to /tmp’s dir: ‘/’. Unlike
any other path output by dirOf, / ends with a slash. We don’t want
trailing slashes here since we will append another slash in the next
comoponent, so clear s like we would if it was a symlink to an absoute
path.

This should fix at least part of the issue in
https://github.com/NixOS/nix/issues/4822, will need confirmation that
it actually fixes the problem to close though.

Introduced in f3f228700a.

559a504da7 sandbox: allow SystemVersionCompat.plist on Darwin
For whatever reason, many programs trying to access SystemVersion.plist
also open SystemVersionCompat.plist; this includes Python code and
coreutils’ `cat(1)` (but not the native macOS `/bin/cat`). Illustratory
`dtruss(1m)` output:

    open("/System/Library/CoreServices/SystemVersion.plist\0", 0x0, 0x0)		 = 3 0
    open("/System/Library/CoreServices/SystemVersionCompat.plist\0", 0x0, 0x0)		 = 4 0

I assume this is a Big Sur change relating to the 10.16.x/11.x
version compatibility divide and that it’s something along the lines of
a hook inside libSystem.

Fixes a lot of sandboxed package builds under Big Sur.

9a14335845 Relock wait for build slot goals
When we don’t have enough free job slots to run a goal, we put it in
the waitForBuildSlot list & unlock its output locks. This will
continue from where we left off (tryLocalBuild). However, we need the
locks to get reacquired when/if the goal ever restarts. So, we need to
send it back through tryToBuild to get reqacquire those locks.

I think this bug was introduced in
https://github.com/NixOS/nix/pull/4570. It leads to some builds
starting without proper locks.

b66234134f Add a realisations disk cache
Similar to the nar-info disk cache (and using the same db).
This makes rebuilds muuch faster.

- This works regardless of the ca-derivations experimental feature.
  I could modify the logic to not touch the db if the flag isn’t there,
  but given that this is a trash-able local cache, it doesn’t seem to be
  really worth it.
- We could unify the `NARs` and `Realisation` tables to only have one
  generic kv table. This is left as an exercise to the reader.
- I didn’t update the cache db version number as the new schema just
  adds a new table to the previous one, so the db will be transparently
  migrated and is backwards-compatible.

1e3a9033b7 Use derivation output name from toDerivation
This was previously done in https://github.com/NixOS/nix/pull/4515 but
got clobbered away in https://github.com/NixOS/nix/pull/4594.

--------------------------------------------------------------------------------

This fixes an issue where derivations with a primary output that is
not "out" would fail with:

$ nix profile install nixpkgs#sqlite
error: opening directory '/nix/store/2a2ydlgyydly5czcc8lg12n6qqkfz863-sqlite-3.34.1-bin': No such file or directory

This happens because while derivations produce every output when
built, you might not have them if you didn't build the derivation
yourself (for instance, the store path was fetch from a binary cache).
This uses outputName provided from DerivationInfo which appears to
match the first output of the derivation.

      foo = nixpkgs.lib.evalModules {
        modules = [
          {
            options.foo.bar = with nixpkgs.lib; mkOption { type = types.package; };
          }
          {
            foo.bar = ./.;
          }

97dde3cdd9 libutil: allow decompression with none/empty method
The S3 store relies on the ability to be able to decompress things with
an empty method, because it just passes the value of the Content-Encoding
directly to decompress.

If the file is not compressed, then this will cause the compression
routine to get confused.

This caused NixOS/nixpkgs#120120.

428062e578 Get deriver when passing --derivation

$ nix path-info --derivation /nix/store/0pisd259nldh8yfjvw663mspm60cn5v8-hello-2.10

now gives

/nix/store/qp724w90516n4bk5r9gfb37vzmqdh3z7-hello-2.10.drv

instead of "".

If no deriver is available, Nix now errors instead of silently
ignoring that argument.

8d66f5f110 Make nix shell fallback to static outputs when needed
In case of pure input-addressed derivations, the build loop doesn't
guaranty that the realisations are stored in the db (if the output paths
are already there or can be substituted, the realisations won't be
registered). This caused `nix shell` to fail in some cases because it
was assuming that the realisations were always existing.

A better (but more involved) fix would probably to ensure that we always
register the realisations, but in the meantime this patches the surface
issue.

libcmd/installables: force re-evaluation of cached failures
I think that it's not very helpful to get "cached failures" in a wrong
`flake.nix`. This can be very confusing when debugging a Nix expression.
See for instance NixOS/nixpkgs#118115.

In fact, the eval cache allows a forced reevaluation which is used for
e.g. `nix eval`.

This change makes sure that this is the case for `nix build` as well. So
rather than

    λ ma27 [~/Projects/exp] → ../nix/outputs/out/bin/nix build -L --rebuild --experimental-features 'nix-command flakes'
    error: cached failure of attribute 'defaultPackage.x86_64-linux'

the evaluation of already-evaluated (and failed) attributes looks like
this now:

    λ ma27 [~/Projects/exp] → ../nix/outputs/out/bin/nix build -L --rebuild --experimental-features 'nix-command flakes'
    error: attribute 'hell' missing

libexpr: misc improvements for proper error position
When working on some more complex Nix code, there are sometimes rather
unhelpful or misleading error messages, especially if coerce-errors are
thrown.

This patch is a first steps towards improving that. I'm happy to file
more changes after that, but I'd like to gather some feedback first.

To summarize, this patch does the following things:

* Attrsets (a.k.a. `Bindings` in `libexpr`) now have a `Pos`. This is
  helpful e.g. to identify which attribute-set in `listToAttrs` is
  invalid.

* The `Value`-struct has a new method named `determinePos` which tries
  to guess the position of a value and falls back to a default if that's
  not possible.

  This can be used to provide better messages if a coercion fails.

* The new `determinePos`-API is used by `builtins.concatMap` now. With
  that change, Nix shows the exact position in the error where a wrong
  value was returned by the lambda.

  To make sure it's still obvious that `concatMap` is the problem,
  another stack-frame was added.

* The changes described above can be added to every other `primop`, but
  first I'd like to get some feedback about the overall approach.

primops/derivation: use position of currently evaluated attribute
* The position of the `name`-attribute appears in the trace.
* If e.g. `meta` has no `outPath`-attribute, a `cannot coerce set to
  string` error will be thrown where `pos` points to `name =` which is
  highly misleading.

could fail with "Too many open files". So now we do some explicit

their temporary internal state, but that would be a bigger refactor.

This avoids an ambiguity where the `StorePathWithOutputs { drvPath, {}

context.

It also brings the internals closer in line to the new CLI, by
generalizing the `Buildable` type is used there and makes that
distinction already.

In doing so, relegate `StorePathWithOutputs` to being a type just for
backwards compatibility (CLI and RPC).

This fixes builtins.fetchGit { url = ...; ref = "HEAD"; }, that works in

  error: program 'git' failed with exit code 128

The documentation for builtins.fetchGit says ref = "HEAD" is the
default, so it should also be supported to explicitly pass it.

I came across this issue because poetry2nix can use ref = "HEAD" in some
situations.

- In a2b69660a9, legacy SSH gated new CAS
  info on version 6, but version 5 in the server. It is now 6
  everywhere.

Additionally, legacy ssh was sending over more metadata than the daemon
one was. The daemon now sends that data too.

Fix Nix to properly work with stores using a scoped IPv6 address
According to RFC4007[1], IPv6 addresses can have a so-called zone_id
separated from the actual address with `%` as delimiter. In contrast to
Nix 2.3, the version on `master` doesn't recognize it as such:

    $ nix ping-store --store ssh://root@fe80::1%18 --experimental-features nix-command
    warning: 'ping-store' is a deprecated alias for 'store ping'
    error: --- Error ----------------------------------------------------------------- nix
    don't know how to open Nix store 'ssh://root@fe80::1%18'

I modified the IPv6 match-regex accordingly to optionally detect this
part of the address. As we don't seem to do anything special with it, I
decided to leave it as part of the URL for now.

3e6017f911 pathInfoIsTrusted -> pathInfoIsUntrusted
I guess the rationale behind the old name wath that
`pathInfoIsTrusted(info)` returns `true` iff we would need to `blindly`
trust the path (because it has no valid signature and `requireSigs` is
set), but I find it to be a really confusing footgun because it's quite
natural to give it the opposite meaning.

nix-build: set execfail
When starting a nix-shell with `-i` it was previously possible for it to
silently fail in the scenario where the specified interpreter didn't
exist. This happened due to the `exec` call masking the issue.

With this change we enable `execfail`, which causes the script using
`nix-shell` as interpreter to correctly exit with code 127.

Fixes: #4598

fc6bfb261d libfetchers/tarball: Lock on effectiveUrl
Basically, if a tarball URL is used as a flake input, and the URL leads
to a redirect, the final redirect destination would be recorded as the
locked URL.

This allows tarballs under https://nixos.org/channels to be used as
flake inputs. If we, as before, lock on to the original URL it would

68f4c728ec Split {,local-}derivation-goal.{cc,hh}
This separates the scheduling logic (including simple hook pathway) from
the local-store needing code.

This should be the final split for now. I'm reasonably happy with how
it's turning out, even before I'm done moving code into
`local-derivation-goal`. Benefits:

1. This will help "witness" that the hook case is indeed a lot simpler,
   and also compensate for the increased complexity that comes from
   content-addressed derivation outputs.

2. It also moves us ever so slightly towards a world where we could use
   off-the-shelf storage or sandboxing, since `local-derivation-goal`
   would be gutted in those cases, but `derivation-goal` should remain
   nearly the same.

The new `#if 0` in the new files will be deleted in the following
commit. I keep it here so if it turns out more stuff can be moved over,
it's easy to do so in a way that preserves ordering --- and thus
prevents conflicts.

N.B.
```sh
git diff HEAD^^ --color-moved --find-copies-harder --patience --stat
```
makes nicer output.

ba1a256d08 Make DerivationGoal::drv a full Derivation
This field used to be a `BasicDerivation`, but this `BasicDerivation`
was downcasted to a `Derivation` when needed (implicitely or not), so we
might as well make it a full `Derivation` and upcast it when needed.

This also allows getting rid of a weird duplication in the way we
compute the static output hashes for the derivation. We had to
do it differently and in a different place depending on whether the
derivation was a full derivation or just a basic drv, but we can now do
it unconditionally on the full derivation.

2de232d2b3 Add x86_64 compute levels as additional system types
When performing distributed builds of machine learning packages, it
would be nice if builders without the required SIMD instructions can
be excluded as build nodes.

Since x86_64 has accumulated a large number of different instruction
set extensions, listing all possible extensions would be unwieldy.
AMD, Intel, Red Hat, and SUSE have recently defined four different
microarchitecture levels that are now part of the x86-64 psABI
supplement and will be used in glibc 2.33:

https://gitlab.com/x86-psABIs/x86-64-ABI
https://lwn.net/Articles/844831/

This change uses libcpuid to detect CPU features and then uses them to
add the supported x86_64 levels to the additional system types. For
example on a Ryzen 3700X:

$ ~/aps/bin/nix -vv --version | grep "Additional system"
Additional system types: i686-linux, x86_64-v1-linux, x86_64-v2-linux, x86_64-v3-linux

libutil: EPERM from kill(-1, ...) is fine
I tested a trivial program that called kill(-1, SIGKILL), which was
run as the only process for an unpriveleged user, on Linux and
FreeBSD.  On Linux, kill reported success, while on FreeBSD it failed
with EPERM.

POSIX says:

> If pid is -1, sig shall be sent to all processes (excluding an
> unspecified set of system processes) for which the process has
> permission to send that signal.

and

> The kill() function is successful if the process has permission to
> send sig to any of the processes specified by pid.  If kill() fails,
> no signal shall be sent.

and

> [EPERM]
>     The process does not have permission to send the signal to any
>     receiving process.

My reading of this is that kill(-1, ...) may fail with EPERM when
there are no other processes to kill (since the current process is
ignored).  Since kill(-1, ...) only attempts to kill processes the
user has permission to kill, it can't mean that we tried to do
something we didn't have permission to kill, so it should be fine to
interpret EPERM the same as success here for any POSIX-compliant
system.

This fixes an issue that Mic92 encountered[1] when he tried to review a
Nixpkgs PR on FreeBSD.

d0e34c85f8 libcmd/markdown: handle allocation errors in lowdown_term_rndr
We upgrade to lowdown 0.8.0 [1] which contains a fix/improvement to a
behavior mentioned in this issue thread [2] where a big part of
lowdown's API would just call exit(1) on allocation errors since that
is a satisfying behavior for the lowdown binary.

Now lowdown_term_rndr returns 0 if an allocation error occurred which we
check for in libcmd/markdown.cc.

Also the extern "C" { } wrapper around lowdown.h has been removed as it
is not necessary.

e38cd5becb Always enter first level of attrset in nix search
This makes nix search always go through the first level of an
attribute set, even if it's not a top level attribute. For instance,
you can now list all GHC compilers with:

$ nix search nixpkgs#haskell.compiler
...

This is similar to how nix-env works when you pass in -A.

3d1bbabe55 Use derivation output name from toDerivation
This fixes an issue where derivations with a primary output that is
not "out" would fail with:

$ nix profile install nixpkgs#sqlite
error: opening directory '/nix/store/2a2ydlgyydly5czcc8lg12n6qqkfz863-sqlite-3.34.1-bin': No such file or directory

This happens because while derivations produce every output when
built, you might not have them if you didn't build the derivation
yourself (for instance, the store path was fetch from a binary cache).
This uses outputName provided from DerivationInfo which appears to
match the first output of the derivation.

9355ecd543 Add a new Cmd type working on RealisedPaths
Where a `RealisedPath` is a store path with its history, meaning either
an opaque path for stuff that has been directly added to the store, or a
`Realisation` for stuff that has been built by a derivation

This is a low-level refactoring that doesn't bring anything by itself
(except a few dozen extra lines of code :/ ), but raising the
abstraction level a bit is important on a number of levels:

- Commands like `nix build` have to query for the realisations after the
  build is finished which is fragile (see
  27905f12e4a7207450abe37c9ed78e31603b67e1 for example). Having them
  oprate directly at the realisation level would avoid that
- Others like `nix copy` currently operate directly on (built) store
  paths, but need a bit more information as they will need to register
  the realisations on the remote side

8d4268d190 Improve error formatting
Changes:

* The divider lines are gone. These were in practice a bit confusing,
  in particular with --show-trace or --keep-going, since then there
  were multiple lines, suggesting a start/end which wasn't the case.

* Instead, multi-line error messages are now indented to align with
  the prefix (e.g. "error: ").

* The 'description' field is gone since we weren't really using it.

* 'hint' is renamed to 'msg' since it really wasn't a hint.

* The error is now printed *before* the location info.

* The 'name' field is no longer printed since most of the time it
  wasn't very useful since it was just the name of the exception (like
  EvalError). Ideally in the future this would be a unique, easily
  googleable error ID (like rustc).

* "trace:" is now just "…". This assumes error contexts start with
  something like "while doing X".

Example before:

  error: --- AssertionError ---------------------------------------------------------------------------------------- nix

In particular this means that 7c2e9ca597/contrib/nix/nar/nar.go (L61-L71) can be removed and only the bits that are required to establish trust needs to be published in the Trustix build logs.

7af743470c Make public keys and requireSigs local-store specific again
Thanks @regnat and @edolstra for catching this and comming up with the
solution.

They way I had generalized those is wrong, because local settings for
non-local stores is confusing default. And due to the nature of C++
inheritance, fixing the defaults is more annoying than it should be.
Additionally, I thought we might just drop the check in the substitution
logic since `Store::addToStore` is now streaming, but @regnat rightfully
pointed out that as it downloads dependencies first, that would still be
too late, and also waste effort on possibly unneeded/unwanted
dependencies.

The simple and correct thing to do is just make a store method for the
boolean logic, keeping all the setting and key stuff the way it was
before. That new method is both used by `LocalStore::addToStore` and the
substitution goal check. Perhaps we might eventually make it fancier,
e.g. sending the ValidPathInfo to remote stores for them to validate,
but this is good enough for now.

f69820417f Set kern.curproc_arch_affinity=0 to escape Rosetta
By default, once you enter x86_64 Rosetta 2, macOS will try to run
everything in x86_64. So an x86_64 Nix will still try to use x86_64
even when system = aarch64-darwin. To avoid this we can set
kern.curproc_arch_affinity sysctl. With kern.curproc_arch_affinity=0,
we ignore this preference.

This is based on how
https://opensource.apple.com/source/system_cmds/system_cmds-880.40.5/arch.tproj/arch.c.auto.html
works. Completely undocumented, but seems to work!

Note, you can verify this works with this impure Nix expression:

```
  {
    a = derivation {
      name = "a";
      system = "aarch64-darwin";
      builder = "/bin/sh";
      args = [ "-e" (builtins.toFile "builder" ''
        [ "$(/usr/bin/arch)" = arm64 ]
        [ "$(/usr/bin/arch -arch x86_64 /bin/sh -c /usr/bin/arch)" = i386 ]
        [ "$(/usr/bin/arch -arch arm64 /bin/sh -c /usr/bin/arch)" = arm64 ]
        /usr/bin/touch $out
      '') ];
    };

    b = derivation {
      name = "b";
      system = "x86_64-darwin";
      builder = "/bin/sh";
      args = [ "-e" (builtins.toFile "builder" ''
        [ "$(/usr/bin/arch)" = i386 ]
        [ "$(/usr/bin/arch -arch x86_64 /bin/sh -c /usr/bin/arch)" = i386 ]
        [ "$(/usr/bin/arch -arch arm64 /bin/sh -c /usr/bin/arch)" = arm64 ]
        /usr/bin/touch $out
      '') ];
    };

44fd7a05b6 Don't let 'preferLocalBuild' override 'max-jobs=0'
This resolves #3810 by changing the behavior of `max-jobs = 0`, so
that specifying the option also avoids local building of derivations
with the attribute `preferLocalBuild = true`.

988dd0a65f Fix conversion from JSON to fetch attributes
It appears as through the fetch attribute, which
is simply a variant with 3 elements, implicitly
converts boolean arguments to integers. One must
use Explicit<bool> to correctly populate it with
a boolean. This was missing from the implementation,
and resulted in clearly boolean JSON fields being
treated as numbers.

Add explicit allRefs = true; argument to fetchGit
Sometimes it's necessary to fetch a git repository at a revision and
it's unknown which ref contains the revision in question. An example
would be a Cargo.lock which only provides the URL and the revision when
using a git repository as build input.

However it's considered a bad practice to perform a full checkout of a
repository since this may take a lot of time and can eat up a lot of
disk space. This patch makes a full checkout explicit by adding an
`allRefs` argument to `builtins.fetchGit` which fetches all refs if
explicitly set to true.

Closes #2409

Provide a more meaningful error-message for builtins.fetchGit if a revision can't be checked out
A common pitfall when using e.g. `builtins.fetchGit` is the `fatal: not
a tree object`-error when trying to fetch a revision of a git-repository
that isn't on the `master` branch and no `ref` is specified.

In order to make clear what's the problem, I added a simple check
whether the revision in question exists and if it doesn't a more
meaningful error-message is displayed:

```
nix-repl> builtins.fetchGit { url = "https://github.com/owner/myrepo"; rev = "<commit not on master>"; }
moderror: --- Error -------------------------------------------------------------------- nix
Cannot find Git revision 'bf1cc5c648e6aed7360448a3745bb2fe4fbbf0e9' in ref 'master' of repository 'https://gitlab.com/Ma27/nvim.nix'! Please make sure that the rev exists on the ref you've specified or add allRefs = true; to fetchGit.
```

4d45839499 Fix the detection of already built drv outputs
PRs #4370 and #4348 had a bad interaction in that the second broke the fist
one in a not trivial way.

The issue was that since #4348 the logic for detecting whether a
derivation output is already built requires some logic that was specific
to the `LocalStore`.

It happens though that most of this logic could be upstreamed to any `Store`,
which is what this commit does.

cac8d5b742 Don't ignore an absent drv file in queryPartialDrvOutputMap
This ignore was here because `queryPartialDrvOutputMap` was used both
1. as a cache to avoid having to re-read the derivation (when gc-ing for
example), and
2. as the source of truth for ca realisations

The use-case 2. required it to be able to work even when the derivation
wasn't there anymore (see https://github.com/NixOS/nix/issues/4138).
However, this use-case is now handled by `queryRealisation`, meaning
that we can safely error out if the derivation isn't there anymore

6e899278d3 Better detect when buildPaths would be a no-op
`buildPaths` can be called even for stores where it's not defined in case it's
bound to be a no-op.
The “no-op detection” mechanism was only detecting the case wher `buildPaths`
was called on a set of (non-drv) paths that were already present on the store.

This commit extends this mechanism to also detect the case where `buildPaths`
is called on a set of derivation outputs which are already built on the store.

This only works with the ca-derivations flag. It could be possible to
extend this to also work without it, but it would add quite a bit of
complexity, and it's not used without it anyways.

7080321618 Use the fs accessor for readInvalidDerivation
Extend `FSAccessor::readFile` to allow not checking that the path is a
valid one, and rewrite `readInvalidDerivation` using this extended
`readFile`.

Several places in the code use `readInvalidDerivation`, either because
they need to read a derivation that has been written in the store but
not registered yet, or more generally to prevent a deadlock because
`readDerivation` tries to lock the state, so can't be called from a
place where the lock is already held.
However, `readInvalidDerivation` implicitely assumes that the store is a
`LocalFSStore`, which isn't always the case.

The concrete motivation for this is that it's required for `nix copy
--from someBinaryCache` to work, which is tremendously useful for the
tests.

bab1cda0e6 Use the hash modulo in the derivation outputs
Rather than storing the derivation outputs as `drvPath!outputName` internally,
store them as `drvHashModulo!outputName` (or `outputHash!outputName` for
fixed-output derivations).

This makes the storage slightly more opaque, but enables an earlier
cutoff in cases where a fixed-output dependency changes (but keeps the
same output hash) − same as what we already do for input-addressed
derivations.

3ac9d74eb1 Rework the db schema for derivation outputs
Add a new table for tracking the derivation output mappings.

We used to hijack the `DerivationOutputs` table for that, but (despite its
name), it isn't a really good fit:

- Its entries depend on the drv being a valid path, making it play badly with
  garbage collection and preventing us to copy a drv output without copying
  the whole drv closure too;
- It dosen't guaranty that the output path exists;

By using a different table, we can experiment with a different schema better
suited for tracking the output mappings of CA derivations.
(incidentally, this also fixes #4138)

58cdab64ac Store metadata about drv outputs realisations
For each known realisation, store:
- its output
- its output path

This comes with a set of needed changes:

- New `realisations` module declaring the types needed for describing
  these mappings
- New `Store::registerDrvOutput` method registering all the needed informations
  about a derivation output (also replaces `LocalStore::linkDeriverToPath`)
- new `Store::queryRealisation` method to retrieve the informations for a
  derivations

This introcudes some redundancy on the remote-store side between
`wopQueryDerivationOutputMap` and `wopQueryRealisation`.
However we might need to keep both (regardless of backwards compat)
because we sometimes need to get some infos for all the outputs of a
derivation (where `wopQueryDerivationOutputMap` is handy), but all the
stores can't implement it − because listing all the outputs of a
derivation isn't really possible for binary caches where the server
doesn't allow to list a directory.

libstore/openStore: fix stores with IPv6 addresses
In `nixStable` (2.3.7 to be precise) it's possible to connect to stores
using an IPv6 address:

  nix ping-store --store ssh://root@2001:db8::1

This is also useful for `nixops(1)` where you could specify an IPv6
address in `deployment.targetHost`.

However, this behavior is broken on `nixUnstable` and fails with the
following error:

  $ nix store ping --store ssh://root@2001:db8::1
  don't know how to open Nix store 'ssh://root@2001:db8::1'

This happened because `openStore` from `libstore` uses the `parseURL`
function from `libfetchers` which expects a valid URL as defined in
RFC2732. However, this is unsupported by `ssh(1)`:

  $ nix store ping --store 'ssh://root@[2001:db8::1]'
  cannot connect to 'root@[2001:db8::1]'

This patch now allows both ways of specifying a store (`root@2001:db8::1`) and
also `root@[2001:db8::1]` since the latter one is useful to pass query
parameters to the remote store.

In order to achieve this, the following changes were made:

* The URL regex from `url-parts.hh` now allows an IPv6 address in the
  form `2001:db8::1` and also `[2001:db8::1]`.

* In `libstore`, a new function named `extractConnStr` ensures that a
  proper URL is passed to e.g. `ssh(1)`:

  * If a URL looks like either `[2001:db8::1]` or `root@[2001:db8::1]`,
    the brackets will be removed using a regex. No additional validation
    is done here as only strings parsed by `parseURL` are expected.

  * In any other case, the string will be left untouched.

* The rules above only apply for `LegacySSHStore` and `SSHStore` (a.k.a
  `ssh://` and `ssh-ng://`).

Unresolved questions:

* I'm not really sure whether we want to allow both variants of IPv6
  addresses in the URL parser. However it should be noted that both seem
  to be possible according to RFC2732:

  > This document incudes an update to the generic syntax for Uniform
  > Resource Identifiers defined in RFC 2396 [URL].  It defines a syntax
  > for IPv6 addresses and allows the use of "[" and "]" within a URI
  > explicitly for this reserved purpose.

* Currently, it's not supported to specify a port number behind the
  hostname, however it seems as this is not really supported by the URL
  parser. Hence, this is probably out of scope here.

c87267c2a4 Store the final drv outputs in memory when building remotely
The `DerivationGoal` has a variable storing the “final” derivation
output paths that is used (amongst other things) to fill the environment
for the post build hook. However this variable wasn't set when the
build-hook is used, causing a crash when both hooks are used together.

Fix this by setting this variable (from the informations in the db) after a run
of the post build hook.

4b9acf4e21 Use posix_spawn_setbinpref_np to advise which architecture to run
When running universal binaries like /bin/bash, Darwin XNU will choose
which architecture of the binary to use based on "binary preferences".
This change sets that to the current platform for aarch64 and x86_64
builds. In addition it now uses posix_spawn instead of the usual
execve. Note, that this does not prevent the other architecture from
being run, just advises which to use.

Unfortunately, posix_spawnattr_setbinpref_np does not appear to be
inherited by child processes in x86_64 Rosetta 2 translations, meaning
that this will not always work as expected.

For example:

  {
    arm = derivation {
      name = "test";
      system = "aarch64-darwin";
      builder = "/bin/bash";
      args = [ "-e" (builtins.toFile "test" ''
        set -x
        /usr/sbin/sysctl sysctl.proc_translated
        /usr/sbin/sysctl sysctl.proc_native
        [ "$(/usr/bin/arch)" = arm64 ]
        /usr/bin/touch $out
      '') ];
    };
    rosetta = derivation {
      name = "test";
      system = "x86_64-darwin";
      builder = "/bin/bash";
      args = [ "-e" (builtins.toFile "test" ''
        set -x
        /usr/sbin/sysctl sysctl.proc_translated
        /usr/sbin/sysctl sysctl.proc_native
        [ "$(/usr/bin/arch)" = i386 ]
        echo It works!
        /usr/bin/touch $out
      '') ];
    };
  }

`arm' fails on x86_64-compiled Nix, but `arm' and `rosetta' succeed on
aarch64-compiled Nix. I suspect there is a way to fix this since:

  $ /usr/bin/arch -arch x86_64 /bin/bash \
    -c '/usr/bin/arch -arch arm64e /bin/bash -c /usr/bin/arch'
  arm64

seems to work correctly. We may need to wait for Apple to update
system_cmds in opensource.apple.com to find out how though.

9b1824ecbd Add extraPlatforms for Rosetta 2 macOS
macOS systems with ARM64 can utilize a translation layer at
/Library/Apple/usr/libexec/oah to run x86_64 binaries. This change
makes Nix recognize that and it to "extra-platforms". Note that there
are two cases here since Nix could be built for either x86_64 or
aarch64. In either case, we can switch to the other architecture.
Unfortunately there is not a good way to prevent aarch64 binaries from
being run in x86_64 contexts or vice versa - programs can always
execute programs for the other architecture.

01db455733 Fix deadlock in nix-store when max-connections=1
This fixes a bug I encountered where `nix-store -qR` will deadlock when
the `--include-outputs` flag is passed and `max-connections=1`.

The deadlock occurs because `RemoteStore::queryDerivationOutputs` takes
the only connection from the connection pool and uses it to check the
daemon version. If the version is new enough, it calls
`Store::queryDerivationOutputs`, which eventually calls
`RemoteStore::queryPartialDerivationOutputMap`, where we take another
connection from the connection pool to check the version again. Because
we still haven't released the connection from the caller, this waits for
a connection to be available, causing a deadlock.

This diff solves the issue by using `getProtocol` to check the protocol
version in the caller `RemoteStore::queryDerivationOutputs`, which
immediately frees the connection back to the pool before returning the
protocol version. That way we've already freed the connection by the
time we call `RemoteStore::queryPartialDerivationOutputMap`.

Allow substituting paths when building remotely using ssh-ng://
Until now, it was not possible to substitute missing paths from e.g.
`https://cache.nixos.org` on a remote server when building on it using
the new `ssh-ng` protocol.

This is because every store implementation except legacy `ssh://`
ignores the substitution flag passed to `Store::queryValidPaths` while
the `legacy-ssh-store` substitutes the remote store using
`cmdQueryValidPaths` when the remote store is opened with `nix-store
--serve`.

This patch slightly modifies the daemon protocol to allow passing an
integer value suggesting whether to substitute missing paths during
`wopQueryValidPaths`. To implement this on the daemon-side, the
substitution logic from `nix-store --serve` has been moved into a
protected method named `Store::substitutePaths` which gets currently
called from `LocalStore::queryValidPaths` and `Store::queryValidPaths`
if `maybeSubstitute` is `true`.

Fixes #2770

This makes it even clearer which of the two hashes was specified in the
nix files. Some may think that "wanted" and "got" is obvious, but:
"got" could mean "got in nix file" and "wanted" could mean "want to see in nix file".

f9438fb64a nix develop: Add --redirect flag to redirect dependencies
This is primarily useful if you're hacking simultaneously on a package
and one of its dependencies. E.g. if you're hacking on Hydra and Nix,
you would start a dev shell for Nix, and then a dev shell for Hydra as
follows:

  $ nix develop \
    --redirect .#hydraJobs.build.x86_64-linux.nix ~/Dev/nix/outputs/out \
    --redirect .#hydraJobs.build.x86_64-linux.nix.dev ~/Dev/nix/outputs/dev

(This assumes hydraJobs.build.x86_64-linux has a passthru.nix
attribute. You can also use a store path.)

This causes all references in the environment to those store paths to
be rewritten to ~/Dev/nix/outputs/{out,dev}. Note: unfortunately, you
may need to set LD_LIBRARY_PATH=~/Dev/nix/outputs/out/lib because
Nixpkgs' ld-wrapper only adds -rpath entries for -L flags that point
to the Nix store.

libmain/progress-bar: don't trim whitespace on the left
When running `nix build -L` it can be fairly hard to read the output if
the build program intentionally renders whitespace on the left. A
typical example is `g++` displaying compilation errors.

With this patch, the whitespace on the left is retained to make the log
more readable:

```
foo> no configure script, doing nothing
foo> building
foo> foobar.cc: In function 'int main()':
foo> foobar.cc:5:5: error: 'wrong_func' was not declared in this scope
foo>     5 |     wrong_func(1);
foo>       |     ^~~~~~~~~~
error: --- Error ------------------------------------------------------------------------------------- nix
error: --- Error --- nix-daemon

Use "?dir=..." portion of "registry add" local path specification.
The registry targets generally follow a URL formatting schema with
support for a query parameter of "?dir=subpath" to specify a sub-path
location below the URL root.

Alternatively, an absolute path can be specified.  This specification
mode accepts the query parameter but ignores/drops it.  It would
probably be better to either (a) disallow the query parameter for the
path form, or (b) recognize the query parameter and add to the path.

This patch implements (b) for consistency, and to make it easier for
tooling that might switch between a remote git reference and a local
path reference.

Update to use access-tokens configuration for github/gitlab access.
This change provides support for using access tokens with other
instances of GitHub and GitLab beyond just github.com and
gitlab.com (especially company-specific or foundation-specific
instances).

This change also provides the ability to specify the type of access
token being used, where different types may have different handling,
based on the forge type.

Fix max-jobs option
After 0ed946aa61, max-jobs setting (-j/--max-jobs)
stopped working.

The reason was that nrLocalBuilds (which compared to maxBuildJobs to figure
out whether the limit is reached or not) is not incremented yet when tryBuild
is started; So, the solution is to move the check to tryLocalBuild.

Serialize SandboxMode enum to string for JSON
Rather than showing an integer as the default, instead show the boolean
referenced in the description.

The nix.conf.5 manpage used to show "default: 0", which is unnecessarily
opaque and confusing (doesn't 0 mean false, even though the default is
true?); now it properly shows that the default is true.

nix-prefetch-url: Add --executable flag
pkgs.fetchurl supports an executable argument, which is especially nice
when downloading a large executable. This patch adds the same option to
nix-prefetch-url.

I have tested this to work on the simple case of prefetching a little
executable:

1. nix-prefetch-url --executable https://my/little/script
2. Paste the hash into a pkgs.fetchurl-based package, script-pkg.nix
3. Delete the output from the store to avoid any misidentified artifacts
4. Realise the package script-pkg.nix
5. Run the executable

I repeated the above while using --name, as well.

I suspect --executable would have no meaningful effect if combined with
--unpack, but I have not tried it.

libfetchers/github: allow url attribute
Since 108debef6f we allow a
`url`-attribute for the `github`-fetcher to fetch tarballs from
self-hosted `gitlab`/`github` instances.

However it's not used when defining e.g. a flake-input

    foobar = {
        type = "github";
        url = "gitlab.myserver";
        /* ... */
    }

and breaks with an evaluation-error:

    error: --- Error --------------------------------------nix
    unsupported input attribute 'url'
    (use '--show-trace' to show detailed location information)

This patch allows flake-inputs to be fetched from self-hosted instances
as well.

a303c0b6dc Fetch commits from github/gitlab using Auth header
`nix flake info` calls the github 'commits' API, which requires
authorization when the repository is private. Currently this request
fails with a 404.

This commit adds an authorization header when calling the 'commits' API.
It also changes the way that the 'tarball' API authenticates, moving the
user's token from a query parameter into the Authorization header.

The query parameter method is recently deprecated and will be disallowed
in November 2020. Using them today triggers a warning email.

Rework the `Store` hierarchy so that there's now one hierarchy for the

StoreConfig-------->Store
    |                 |
    v                 v
SubStoreConfig----->SubStore
    |                 |
    v                 v
SubSubStoreConfig-->SubSubStore
```

(with virtual inheritance to prevent DDD).

c++ data structure.

The goal behind that is that we can create “dummy” instances of each

example)

Fix unspecified behaviour in readStorePathCAMap
When deploying a Hydra instance with current Nix master, most builds
would not run because of errors like this:

  queue monitor: error: --- Error --- hydra-queue-runner
  error: --- UsageError --- nix-daemon
  not a content address because it is not in the form '<prefix>:<rest>': /nix/store/...-somedrv

The last error message is from parseContentAddress, which expects a
colon-separated string, however what we got here is a store path.

Looking at the worker protocol, the following message sent to the Nix
daemon caused the error above:

  0x1E -> wopQuerySubstitutablePathInfos
  0x01 -> Number of paths
  0x16 -> Length of string
  "/nix/store/...-somedrv"
  0x00 -> Length of string
  ""

Looking at writeStorePathCAMap, the store path is indeed the first field
that's transmitted. However, readStorePathCAMap expects it to be the
*second* field *on my machine*, since expression evaluation order is a
classic form of unspecified behaviour[1] in C++.

This has been introduced in https://github.com/NixOS/nix/pull/3689,
specifically in commit 66a62b3189.

626200713b Pass all args when auto-calling a function with an ellipsis
The command line options --arg and --argstr that are used by a bunch of
CLI commands to pass arguments to top-level functions in files go
through the same code-path as auto-calling top-level functions with
their default arguments - this, however, was only passing the arguments
that were *explicitly* mentioned in the formals of the function - in the
case of an as-pattern with an ellipsis (eg args @ { ... }) extra passed
arguments would get omitted. This fixes that to instead pass *all*
specified auto args in the case that our function has an ellipsis.

ed026f7206 Don't try to parse signature check as commit timestamp
When the log.showSignature git setting is enabled, the output of
"git log" contains signature verification information in addition to the
timestamp GitInputScheme::fetch wants:

  $ git log -1 --format=%ct
  gpg: Signature made Sat 07 Sep 2019 02:02:03 PM PDT
  gpg:                using RSA key 0123456789ABCDEF0123456789ABCDEF01234567
  gpg:                issuer "user@example.com"
  gpg: Good signature from "User <user@example.com>" [ultimate] 1567890123
  1567890123

For folks that had log.showSignature set, this caused all nix operations
on flakes to fail:

5ccd94501d Allow trustless building of CA derivations
Include a long comment explaining the policy. Perhaps this can be moved
to the manual at some point in the future.

Also bump the daemon protocol minor version, so clients can tell whether
`wopBuildDerivation` supports trustless CA derivation building. I hope
to take advantage of this in a follow-up PR to support trustless remote
building with the minimal sending of derivation closures.

8d4162ff9e Separate auth and logic for the daemon
Before, processConnection wanted to know a user name and user id, and
`nix-daemon --stdio`, when it isn't proxying to an underlying daemon,
would just assume "root" and 0. But `nix-daemon --stdio` (no proxying)
shouldn't make guesses about who holds the other end of its standard
streams.

Now processConnection takes an "auth hook", so `nix-daemon` can provide
the appropriate policy and daemon.cc doesn't need to know or care what
it is.

Always reset ANSI colors in progress-bar line
When having a message like `waiting for a machine to build X` and
building with `nix build -L`, the log-prefix is always colored yellow[1]
on a small terminal-width as everything (including the ANSI color-reset) is
stripped away.

To work around that problem, this patch explicitly adds an `ANSI_NORMAL`
to the end of the line.

3c75ddc16b nix build (and others): Force re-evaluation of cached errors

This is a bit hacky. Ideally we would automatically re-evaluate the
failed attribute iff we need to print the error message (so in
commands like 'nix search' we wouldn't re-evaluate because we're
suppressing errors).

641c950701 Add hashed-mirrors back
Some users have their own hashed-mirrors setup, that is used to mirror
things in addition to what’s available on tarballs.nixos.org. Although
this should be feasable to do with a Binary Cache, it’s not always
easy, since you have to remember what "name" each of the tarballs has.
Continuing to support hashed-mirrors is cheap, so it’s best to leave
support in Nix. Note that NIX_HASHED_MIRRORS is also supported in
Nixpkgs through fetchurl.nix.

Note that this excludes tarballs.nixos.org from the default, as in
\#3689. All of these are available on cache.nixos.org.

2f4250a416 Add "export" to Nix
This adds a ‘nix export’ command which hooks into nix-bundle. It can
be used in a similar way as nix-bundle, with the benefit of hooking
into the new “app” functionality. For instance,

$ nix export nixpkgs#jq
$ ./jq --help
jq - commandline JSON processor [version 1.6]
...
$ scp jq machine-without-nix:
$ ssh machine-without-nix ./jq
jq - commandline JSON processor [version 1.6]
...

Note that nix-bundle currently requires Linux to run. Other exporters
might not have that requirement.

“exporters” are meant to be reusable, so that, other repos can
implement their own bundling.

Merge legacy fetchGit-builtin with the generic fetchTree-function
The original idea was to implement a git-fetcher in Nix's core that
supports content hashes[1]. In #3549[2] it has been suggested to
actually use `fetchTree` for this since it's a fairly generic wrapper
over the new fetcher-API[3] and already supports content-hashes.

This patch implements a new git-fetcher based on `fetchTree` by
incorporating the following changes:

* Removed the original `fetchGit`-implementation and replaced it with an
  alias on the `fetchTree` implementation.

* Ensured that the `git`-fetcher from `libfetchers` always computes a
  content-hash and returns an "empty" revision on dirty trees (the
  latter one is needed to retain backwards-compatibility).

* The hash-mismatch error in the fetcher-API exits with code 102 as it
  usually happens whenever a hash-mismatch is detected by Nix.

* Removed the `flakes`-feature-flag: I didn't see a reason why this API
  is so tightly coupled to the flakes-API and at least `fetchGit` should
  remain usable without any feature-flags.

* It's only possible to specify a `narHash` for a `git`-tree if either a
  `ref` or a `rev` is given[4].

* It's now possible to specify an URL without a protocol. If it's missing,
  `file://` is automatically added as it was the case in the original
  `fetchGit`-implementation.

libutil/logging: extend internal-json logger to make it more machine-readable
The new error-format is pretty nice from a UX point-of-view, however
it's fairly hard to parse the output e.g. for editor plugins such as
vim-ale[1] that use `nix-instantiate --parse` to determine syntax errors in
Nix expression files.

This patch extends the `internal-json` logger by adding the fields
`line`, `column` and `file` to easily locate an error in a file and the
field `raw_msg` which contains the error-message itself without
code-lines and additional helpers.

An exemplary output may look like this:

```
[nix-shell]$ ./inst/bin/nix-instantiate ~/test.nix --log-format minimal
{"action":"msg","column":1,"file":"/home/ma27/test.nix","level":0,"line":4,"raw_msg":"syntax error, unexpected IF, expecting $end","msg":"<full error-msg with code-lines etc>"}
```

e1de1fe0d8 Make Buildable a std::variant
I think this better captures the intent of what's going on: we either
have an opaque store path, or a drv path with some outputs.

Having this structure will also help us support CA derivations: we'll
have to allow the outpath paths to be optional, so the structure we gain
now makes up for the structure we loose then.

2274f63453 Get rid of basicDerivation::findOutput
It's a tiny function which is:

 - hardly worth abstrating over, and also only used once.

 - doesn't work once we get CA drvs

I rewrote the one callsite to be forwards compatable with CA
derivations, and also potentially more performant: instead of reading in
the derivation it can ust consult the SQLite DB in the common case.

bc73590151 nix edit: call restoreSignals() before execvp-ing the $EDITOR
Currently resizing of the terminal doesn't play nicely with
nix edit when using kakoune as the editor, as it relies on the
SIGWINCH signal which is trapped by nix. How this is not a problem
with e.g. vim is beyond me.

Virtually all other exec* calls are following a call to
restoreSignals(). This commit adds this behavior to nix edit
as well.

anymore. In fact, we can almost remove the method/hashAlgo arguments
since the non-recursive and/or non-SHA256 are almost not used anymore.

We were calculating the nar hash wrong when the file ingestion method
was flat. I don't think there's anything we can do in that case but dump
the file again, so that's what I do.

As an optomization, we again could reuse the original dump for just the
recursive and non-sha256 case, but I rather do that after this fix, and
after my other PRs which deduplicate this code.

Fix gitlab-fetcher to obtain tags and branches
Until now, the `gitlab`-fetcher determined the source's rev by checking
the latest commit of the given `ref` using the
`/repository/branches`-API.

This breaks however when trying to fetch a gitlab-repo by its tag:

```
$ nix repl
nix-repl> builtins.fetchTree gitlab:Ma27/nvim.nix/0.2.0
error: --- Error ------------------------------------------------------------------------------------- nix
unable to download 'https://gitlab.com/api/v4/projects/Ma27%2Fnvim.nix/repository/branches/0.2.0': HTTP error 404 ('')
```

When using the `/commits?ref_name`-endpoint[1] you can pass any kind of
valid ref to the `gitlab`-fetcher.

Please note that this fetches the only first 20 commits on a ref,
unfortunately there's currently no endpoint which only retrieves the
latest commit of any kind of `ref`.

The `m` acts as termination-symbol when declaring graphics. Because
of this, the `;1m` doesn't have any effect and is directly printed to
the console:

34f25124ba Make LocalStore::addToStore(srcPath) run in constant memory
This reduces memory consumption of

  nix-instantiate \
    -E 'with import <nixpkgs> {}; runCommand "foo" { src = ./blender; } "echo foo"' \
    --option nar-buffer-size 10000

(where ./blender is a 1.1 GiB tree) from 1716 to 36 MiB, while still
ensuring that we don't do any write I/O for small source paths (up to
'nar-buffer-size' bytes). The downside is that large paths are now
always written to a temporary location in the store, even if they
produce an already valid store path. Thus, adding large paths might be
slower and run out of disk space. ¯\_(ツ)_/¯ Of course, you can always
restore the old behaviour by setting 'nar-buffer-size' to a very high
value.

ba50c3efa3 Add "uid-range" and "systemd-cgroup" system features
"uid-range" provides 65536 UIDs to a build and runs the build as root
in its user namespace. "systemd-cgroup" allows the build to mount the
systemd cgroup controller (needed for running systemd-nspawn and NixOS
containers).

Also, add a configuration option "auto-allocate-uids" which is needed
to enable these features, and some experimental feature gates.

So to enable support for containers you need the following in
nix.conf:

  experimental-features = auto-allocate-uids systemd-cgroup
  auto-allocate-uids = true
  system-features = uid-range systemd-cgroup

ca2f64bcda Reduce # of UIDs per build to 65536
2^18 was overkill. The idea was to enable multiple containers to run
inside a build. However, those containers can use the same UID range -
we don't really care about perfect isolation between containers inside
a build.

f5fa3de759 Run builds in their own cgroup
Also, run builds in a cgroup namespace (ensuring /proc/self/cgroup
doesn't leak information about the outside world) and mount /sys. This
enables running systemd-nspawn and thus NixOS containers in a Nix
build.

836573a9a2 Dynamically allocate UIDs
Rather than rely on a nixbld group, we now allocate UIDs/GIDs
dynamically starting at a configurable ID (872415232 by default).

Also, we allocate 2^18 UIDs and GIDs per build, and run the build as
root in its UID namespace. (This should not be the default since it
breaks some builds. We probably should enable this conditional on a
requiredSystemFeature.) The goal is to be able to run (NixOS)
containers in a build. However, this will also require some cgroup
initialisation.

The 2^18 UIDs/GIDs is intended to provide enough ID space to run
multiple containers per build, e.g. for distributed NixOS tests.

d38f860c3e Add a way to get all the outputs of a derivation with their label
Generalize `queryDerivationOutputNames` and `queryDerivationOutputs` by
adding a `queryDerivationOutputMap` that returns the map
`outputName=>outputPath`

(not that this is not equivalent to merging the results of
`queryDerivationOutputs` and `queryDerivationOutputNames` as sets don't
preserve the order, so we would end up with an incorrect mapping).

squash! Add a way to get all the outputs of a derivation with their label

f4a5913125 hashed-mirrors: Use parsed derivation output rather than reconstructing it
Now the derivation outputs are parsed up front, we can avoid a reparse
by doing it. Also, this just feels a bit better as the `output*` env
vars are more of a `libnixexpr` interface than `libnixstore` interface:
ultimately, it's the derivation outputs that decide whether the
derivation is fixed-output.

Yes, hashed mirrors might go away with #3689, but this bit of code would
be moved rather than deleted, so it's worth doing a cleanup anyways I
think.

When we merge with master, the new lack of string types make this case

639e20dc3e Prevent '%' in URL from causing crashes
We have a larger problem that passsing computed strings to the first
variable argument of many exception constructors is unsafe because that
first variable argument is interpreted not as a plain string, but format
string, and if it contains '%' boost::format will abort, since there are
no arguments to the format string.

In this particular instance '%' was used as part of an escape code in a
URL, which, when the download failed, caused Nix to abort displaying the
`FileTransferError`.

289b9b8dcf Create a new TeeSink abstraction
This is a bit complex because we want to expose extra functionality the
wrapped class has. Perhaps there is some inheritancy trickery to do this
nicer, but I don't know it, and this is the first thing we tried after a
series of attempts that did build.

This design is kind of like that of Rust's Writer, Reader, or Iter
adapters, which impliment more traits based on what the inner type
implements.

fb05a6adcf Eliminate old TeeSink abstraction
This was introduced in fa125b9b28, and
then "reverted" in 1cf4801108, except that
revert left the struct around doing nothing useful.

We're removing it all the way now because we want to make a new
`TeeSink` complementing the already-exiting `TeeSource`, that is
actually a completely different concept as far as the class hierarchy is
concerned.

c214cda940 Correctly substitute from different storeDir
Originally, the test was only checking for different “real” storeDir.
That’s an easy case to handle, but the much harder one is if different
virtual store dirs are used. To do this, we need the SubstitutionGoal
to know about the ca, so it can recalculate the path to copy it over.
An important note here is that the store path passed to copyStorePath
needs to be one for srcStore - so that queryPathInfo works properly.

This also adds an error message when the store path from queryPathInfo
is different from the one we requested.

79c169d1c6 Allow substituting from different storeDir
Substituters can substitute from one store dir to another with a
little bit of help. The store api just needs to have a CA so it can
recompute the store path based on the new store dir. We can only do
this for fixed output derivations with no references, though.

This function was used in only one place, where it could easily be

after queryDerivationOutputs(), which exists only to make the garbage
collector faster.)

810b2c6a48 nix flake init: Add a '--template' flag
The initial contents of the flake is specified by the
'templates.<name>' or 'defaultTemplate' output of another flake. E.g.

  outputs = { self }: {

    templates = {

      nixos-container = {
        path = ./nixos-container;
        description = "An example of a NixOS container";
      };

    };

  };

allows

  $ nix flake init -t templates#nixos-container

Also add a command 'nix flake new', which is identical to 'nix flake
init' except that it initializes a specified directory rather than the
current directory.

ff1320b850 fetchOrSubstituteTree improvements
Caches tree in addition to lockedRef, and explicitly writes out the logic for different combinations of cached/uncached flakes and indirect/resolved/locked flakes. This eliminates uneccessary calls to lookupInFlakeCache, fetchTree, maybeLookupFlake, and flakeCache.push_back

fb38459d6e Ensure we restrict refspec interpretation while fetching
As `git fetch` may chose to interpret refspec to it's liking, ensure that we
only pass refs that begin with `refs/` as is, otherwise, prepend them with
`refs/heads`. Otherwise, branches named `heads/foo` (I know it's bad, but it's
allowed), would be fetched as `foo`, instead of `heads/foo`.

77007d4eab Improve ref validity checking in fetchGit
The previous regex was too strict and did not match what git was allowing. It
could lead to `fetchGit` not accepting valid branch names, even though they
exist in a repository (for example, branch names containing `/`, which are
pretty standard, like `release/1.0` branches).

The new regex defines what a branch name should **NOT** contain. It takes the
definitions from `refs.c` in https://github.com/git/git and `git help
check-ref-format` pages.

This change also introduces a test for ref name validity checking, which
compares the result from Nix with the result of `git check-ref-format --branch`.

950b46821f Remove TreeInfo
The attributes previously stored in TreeInfo (narHash, revCount,
lastModified) are now stored in Input. This makes it less arbitrary
what attributes are stored where.

As a result, the lock file format has changed. An entry like

    "info": {
      "lastModified": 1585405475,
      "narHash": "sha256-bESW0n4KgPmZ0luxvwJ+UyATrC6iIltVCsGdLiphVeE="
    },
    "locked": {
      "owner": "NixOS",
      "repo": "nixpkgs",
      "rev": "b88ff468e9850410070d4e0ccd68c7011f15b2be",
      "type": "github"
    },

is now stored as

    "locked": {
      "owner": "NixOS",
      "repo": "nixpkgs",
      "rev": "b88ff468e9850410070d4e0ccd68c7011f15b2be",
      "type": "github",
      "lastModified": 1585405475,
      "narHash": "sha256-bESW0n4KgPmZ0luxvwJ+UyATrC6iIltVCsGdLiphVeE="
    },

The 'Input' class is now a dumb set of attributes. All the fetcher
implementations subclass InputScheme, not Input. This simplifies the
API.

Also, fix substitution of flake inputs. This was broken since lazy
flake fetching started using fetchTree internally.

fac0c2d54a Remove addToStore variant as requested by FIXME
The idea is it's always more flexible to consumer a `Source` than a
plain string, and it might even reduce memory consumption.

I also looked at `addToStoreFromDump` with its `// FIXME: remove?`, but
the worked needed for that is far more up for interpretation, so I
punted for now.

inherently flake-related (e.g. fetchTree could also use it to remap
inputs).

InstallableValue::toDerivations() -> InstalllableAttrPath::toDerivations()
InstallableValue::cmd -> InstallableAttrPath::cmd

InstallableValue uses state instead of cmd

'nix run') there is not much point in keeping this around.

nix/search: no error for empty search results if json is enabled
- result list will be always empty if --json is passed
- for scripts an empty search result is not really an error,
  we rather want to distinguish between evaluation errors and empty results

call on the builder pseudo terminal fd. This call is actually only

5a34a473dd builtins.readFile: do not truncate content
This closes #3026 by allowing `builtins.readFile` to read a file with a
wrongly reported file size, for example, files in `/proc` may report a
file size of 0. Reading file in `/proc` is not a good enough motivation,
however I do think it just makes nix more robust by allowing more file
to be read.  Especially, I do considerer the previous behavior to be
dangerous because nix was previously reading truncated files. Examples
of file system which incorrectly report file size may be network file
system or dynamic file system (for performance reason, a dynamic file
system such as FUSE may generate the content of the file on demand).

```
nix-repl> builtins.readFile "/proc/version"
""
```

With this commit:

```
nix-repl> builtins.readFile "/proc/version"
"Linux version 5.6.7 (nixbld@localhost) (gcc version 9.3.0 (GCC)) #1-NixOS SMP Thu Apr 23 08:38:27 UTC 2020\n"
```

Here is a summary of the behavior changes:

- If the reported size is smaller, previous implementation
was silently returning a truncated file content. The new implementation
is returning the correct file content.

- If a file had a bigger reported file size, previous implementation was
failing with an exception, but the new implementation is returning the
correct file content. This change of behavior is coherent with this pull
request.

Open questions

- The behavior is unchanged for correctly reported file size, however
performances may vary because it uses the more complex sink interface.
Considering that sink is used a lot, I don't think this impacts the
performance a lot.
- `builtins.readFile` on an infinite file, such as `/dev/random` may
fill the memory.
- it does not support adding file to store, such as `${/proc/version}`.

Fix long paths permanently breaking GC
Suppose I have a path /nix/store/[hash]-[name]/a/a/a/a/a/[...]/a,
long enough that everything after "/nix/store/" is longer than 4096
(MAX_PATH) bytes.

Nix will happily allow such a path to be inserted into the store,
because it doesn't look at all the nested structure.  It just cares
about the /nix/store/[hash]-[name] part.  But, when the path is deleted,
we encounter a problem.  Nix will move the path to /nix/store/trash, but
then when it's trying to recursively delete the trash directory, it will
at some point try to unlink
/nix/store/trash/[hash]-[name]/a/a/a/a/a/[...]/a.  This will fail,
because the path is too long.  After this has failed, any store deletion
operation will never work again, because Nix needs to delete the trash
directory before recreating it to move new things to it.  (I assume this
is because otherwise a path being deleted could already exist in the
trash, and then moving it would fail.)

This means that if I can trick somebody into just fetching a tarball
containing a path of the right length, they won't be able to delete
store paths or garbage collect ever again, until the offending path is
manually removed from /nix/store/trash.  (And even fixing this manually
is quite difficult if you don't understand the issue, because the
absolute path that Nix says it failed to remove is also too long for
rm(1).)

This patch fixes the issue by making Nix's recursive delete operation
use unlinkat(2).  This function takes a relative path and a directory
file descriptor.  We ensure that the relative path is always just the
name of the directory entry, and therefore its length will never exceed
255 bytes.  This means that it will never even come close to AX_PATH,
and Nix will therefore be able to handle removing arbitrarily deep
directory hierachies.

Since the directory file descriptor is used for recursion after being
used in readDirectory, I made a variant of readDirectory that takes an
already open directory stream, to avoid the directory being opened
multiple times.  As we have seen from this issue, the less we have to
interact with paths, the better, and so it's good to reuse file
descriptors where possible.

I left _deletePath as succeeding even if the parent directory doesn't
exist, even though that feels wrong to me, because without that early
return, the linux-sandbox test failed.

execute without fetching the flake.

With this, 'nix flake show nixpkgs/nixos-20.03 --legacy' executes in

This speeds up the creation of the cache for the nixpkgs flake from

(i.e. running 'nix flake show nixpkgs/nixos-20.03 --legacy') from 4.2s
to 3.4s.

(For comparison, running with --no-eval-cache takes 9.5s, so the
overhead of building the SQLite cache is only 0.7s.)

d2c371927e SourceExprCommand: allocate the vSourceExpr via uncollectable memory
Previously the memory would occasionally be collected during eval since
the GC doesn't consider the member variable as alive / doesn't scan the
region of memory where the pointer lives.

By using the traceable_allocator<T> allocator provided by Boehm GC we
can ensure the memory isn't collected. It should be properly freed when
SourceExprCommand goes out of scope.

never use /var/folders for TMPDIR on darwin
This doesn't just cause problems for nix-store --serve but also results
in certain build failures. Builds that use unix domain sockets in their
tests often fail because the /var/folders prefix already consumes more
than half of the maximum length of socket paths.

    struct sockaddr_un {
       sa_family_t sun_family;               /* AF_UNIX */
       char        sun_path[108];            /* Pathname */

8132d0a12e Fix nix-build --check -K in sandbox w/o root
Temporarily add user-write permission to build directory so that it
can be moved out of the sandbox to the store with a .check suffix.

This is necessary because the build directory has already had its
permissions set read-only, but write permission is required
to update the directory's parent link to move it out of the sandbox.

Updated the related --check "derivation may not be deterministic"
messages to consistently use the real store paths.

Added test for non-root sandbox nix-build --check -K to demonstrate
issue and help prevent regressions.

Remove flake 'edition' field
Future editions of flakes or the Nix language can be supported by
renaming flake.nix (e.g. flake-v2.nix). This avoids a bootstrap
problem where we don't know which grammar to use to parse
flake*.nix. It also allows a project to support multiple flake
editions, in theory.

16a4864759 Delete temporary directory on successful build
With --check and the --keep-failed (-K) flag, the temporary directory
was being retained regardless of whether the build was successful and
reproducible.  This removes the temporary directory, as expected, on
a reproducible check build.

Added tests to verify that temporary build directories are not
retained unnecessarily, particularly when using --check with
--keep-failed.

670feb000a Add 'path' fetcher
This fetchers copies a plain directory (i.e. not a Git/Mercurial
repository) to the store (or does nothing if the path is already a
store path).

One use case is to pin the 'nixpkgs' flake used to build the current
NixOS system, and prevent it from being garbage-collected, via a
system registry entry like this:

  {
      "from": {
          "id": "nixpkgs",
          "type": "indirect"
      },
      "to": {
          "type": "path",
          "path": "/nix/store/rralhl3wj4rdwzjn16g7d93mibvlr521-source",
          "lastModified": 1585388205,
          "rev": "b0c285807d6a9f1b7562ec417c24fa1a30ecc31a"
      },
      "exact": true
  }

Note the fake "lastModified" and "rev" attributes that ensure that the
flake gives the same evaluation results as the corresponding
Git/GitHub inputs.

462421d345 Backport libfetchers from the flakes branch
This provides a pluggable mechanism for defining new fetchers. It adds
a builtin function 'fetchTree' that generalizes existing fetchers like
'fetchGit', 'fetchMercurial' and 'fetchTarball'. 'fetchTree' takes a
set of attributes, e.g.

  fetchTree {
    type = "git";
    url = "https://example.org/repo.git";
    ref = "some-branch";
    rev = "abcdef...";
  }

The existing fetchers are just wrappers around this. Note that the
input attributes to fetchTree are the same as flake input
specifications and flake lock file entries.

All fetchers share a common cache stored in
~/.cache/nix/fetcher-cache-v1.sqlite. This replaces the ad hoc caching
mechanisms in fetchGit and download.cc (e.g. ~/.cache/nix/{tarballs,git-revs*}).

This also adds support for Git worktrees (c169ea5904).

Don't retry on "unsupported protocol" error
When encountering an unsupported protocol, there's no need to retry.
Chances are, it won't suddenly be supported between retry attempts;
error instead. Otherwise, you see something like the following:

    $ nix-env -i -f git://git@github.com/foo/bar
    warning: unable to download 'git://git@github.com/foo/bar': Unsupported protocol (1); retrying in 335 ms
    warning: unable to download 'git://git@github.com/foo/bar': Unsupported protocol (1); retrying in 604 ms
    warning: unable to download 'git://git@github.com/foo/bar': Unsupported protocol (1); retrying in 1340 ms
    warning: unable to download 'git://git@github.com/foo/bar': Unsupported protocol (1); retrying in 2685 ms

With this change, you now see:

    $ nix-env -i -f git://git@github.com/foo/bar
