libarchive's xz offers single threaded xz compression which is very slow
and provides ~10-20Mbps compression speed in addition to maxing a core.
In exchange, it achieves optimal compression ratios among all our
compression methods.
Nonetheless, xz prevent the saturation of 1Gbps+ connections and slow
down significantly decompression for end users. As these connections and
faster hardware is becoming prevalent for cache servers and clients, we
offer to default to zstd.
Lix is a "compress once, decompress many times" application. To avoid
incurring a high penalty to end users very sensitive to compress ratio
(very slow Internet connections), we dampen the consequences of
switching to zstd by increasing the default zstd level to 12.
On one example, xz will compress a 4.4GB file to 632MB, zstd on 12 will
compress it to 775MB, that is a ~18 % increase over the optimal xz
compression. zstd took 18 seconds to produce this file.
Increasing to level 14 leads to a 773MB file while taking 37s.
Increasing to level 16 leads to 735MB file while taking 66s.
Finally, xz took 77s, so a 50 % reduction in time taken to compress in
exchange of an increase of 18 % of the compressed size.
This change will reduce issues encountered in #945 but is probably not
the root cause.

Fixes fj#940.
When running `nix-shell`, the `$NIX_BUILD_TOP` environment variable is
set to `$TMPDIR` or `/tmp`.
nixpkgs stdenv uses $NIX_BUILD_TOP to create `$NIX_BUILD_TOP/env-vars`
which contains all the environment variables set by stdenv. This is used
for debugging purposes in combination with `--keep-failed` to reload the
bash environment of a derivation.
`$TMPDIR` is often unset, therefore, `/tmp/env-vars` was constantly
being created. On a multi-user system or, when you run Lix as root, you
might create a `/tmp/env-vars` with different permission bits.
As a result, `nix-shell` can cease to function because that file will
fail creation for an unprivileged user for example.
fj#940 rightfully remark that the code is not consistent between
nix3-develop and nix-shell and it should be reworked.

The patch adds a flag `--no-instantiate` which only performs evaluation
without instantiating any derivations. Hence, GC root creation is also
skipped. To achieve that, Lix is also put in read-only mode and all
operations that require reading a derivation (e.g. constituents or
listing input derivations) are disabled fallback values are set.
This is a port of an upstream PR[1]. Given the divergence of the
codebases (different restructurings on both ends, no more CA derivations)
I decided to redo large portions from scratch instead of
cherry-picking the patches. Hence, the authorship.
Additionally the clean up of casts down to a local store are removed or
guarded behind an if, as done in the upstream PR.

Information about which commands were executed is really valuable to
debug Lix and is much more user relevant than the vast majority of the
e.g. build loop junk printed at debug level. Currently we have a *whole

I chose to print argv0 rather than the executable path if these differ,
since the code is shorter and since the command could be a fully

`connect-timeout` gets replaced by an exponential backoff for the
download timeout where the initial value is controlled by the setting
`initial-connect-timeout`.
Per iteration, the upper limit of the timeout is increased set to
timeout := min(max_connect_timeout, initial_connect_timeout * 2^i)
I decided to move the entire timeout / tracking of attempts into its own
class to not make the filetransfer implementation more complex. Also,
that allows us to write unit-tests for it.
Setting `--download-attempts` to `0` is forbidden now and an exception
will be thrown. For `--offline` we set it to `1`, the behavior is
equivalent to what it was before: whether the max tries were exceeded is
only checked after the first download exception got thrown, i.e. there's
still one attempt being made.

looks like this:

Floating‐point numbers are annoying to deal with in Nix, so it
optimistically parses integer‐looking literals as Nix‐language
integers where possible. Nixpkgs relies on this behaviour, as it backs
its `lib.toInt` family of functions with `builtins.fromJSON` in lieu
of a real integer‐parsing built‐in, and treats floating‐point
outputs as an error. Therefore, dealing with integer‐looking
JSON number literals that are outside the interoperable range is
unavoidable.
However, this raises the question of how literals that look
like integers, but exceed the range of a Nix‐language integer,
should be handled. The JSON library we use attempts to represent
integer‐looking literals as a unsigned or signed C++ integer type
before falling back to floating‐point numbers.
This means that we were parsing literals below −2⁶³ as
floating‐point numbers, while rejecting ones above (2⁶³ + 1)
with an error. This was done to avoid the C++ undefined behaviour in
the previous code path, but is hard to justify. This change causes
them to both be parsed as floating‐point numbers.
The alternative would be to reject the signed case too. However,
I believe that is less consistent with how JSON handles its single
numeric type, less interoperable with JSON documents found in the wild,
and that it is preferable to avoid the function being needlessly
partial in this case. It does mean that round‐tripping is less
lossless than before, but extreme floating‐point values already
caused these kinds of issues, and from JSON’s point of view that’s
exactly what these literals represent. Only numeric values outside the
RFC’s suggested interoperable range will have any round‐tripping
issues, and we continue to guarantee the behaviour on all values that
can be represented as Nix‐language integers.

Snix's nar-bridge[1] stores NARs under a different URL, i.e.
`nar/snix-castore/<hash>.nar` rather than `nar/<filehash>.nar`. Right
now, when copying into such a store via the http binary-cache, we'd end
up with wrong cache entries that point to the wrong NAR URL.
On Hydra, this is a fatal error, i.e. builds that depend on previously
built paths (that were written to the cache before by the queue runner)
would be aborted because of that.
This patch removes the caching since we'd have to re-fetch the narinfo
to do taht and this can also happen the next time, the narinfo is
queried. Also, removes the negative cache entry indicating that the
store-path doesn't exist in the store.
We don't have any coverage for http-stores so far, so I wrote a small
testcase for the "default" case and the nar-bridge case in functional2
since it has a very nice fixture for an HTTP server ready. I'm aware
that there's a CL for a nicer cache server[2], but given I'm down a
pretty deep rabbit hole by playing around with Snix, I decided to not
finish the CL and write something small for the tests in here. This can
be replaced by the fixtures from that CL later on as well.

Historically, Nix would support copying certificate authorities inside
the sandbox so you could use them.
In addition to that, the primitives consisting of leaking environment
variables via `impureEnvVars` and `extra-sandbox-paths` to render paths
external to the sandbox visible to the builder would also constitute a
mechanism to expose special inodes which should have no influence on the
output result, e.g. interception CAs.
Unfortunately, in nixpkgs, `lib.fetchers.proxyImpureEnvVars` set
`NIX_SSL_CERT_FILE` as an impure environment variable.
A confused user may set `ssl-cert-file` via `NIX_SSL_CERT_FILE` outside the
builder believing that this will set magically the right
`NIX_SSL_CERT_FILE` inside the sandbox, but this is not true.
The combination of impure environment variables and setting `caFile`
creates a weird interaction where `NIX_SSL_CERT_FILE` points to an
"outside the builder's world" inode *AND* `ssl-cert-file` creates
this very same certificate file in /etc/ssl/certs/ca-certificates.crt
without rewriting the environment variable.
This footgun is closed by making these two features mutually
incompatible with a warning and forcibly rewriting the SSL family of
environment variables even if it was set via impure environment
variables.
Users who truly meant to use `impureEnvVars` can obtain the right
behavior by setting `ssl-cert-file` to an empty string and will have to use
`extra-sandbox-paths`.
Users who meant to use `ssl-cert-file` will have everything work
automatically with a warning hinting at nixpkgs *fixing its own bug*,
i.e. passing `NIX_SSL_CERT_FILE` as an impure environment variable and
expecting the Nix interpreter to magically reconcile the diverging
values or expecting the user to actually do the work to render the path
visible available via `extra-sandbox-paths`.

to using a subdirectory of nixStateDir (which is more restrictive).
Fixes CVE-2025-52991.

This allows using a userspace program, pasta, to handle comms between
the build sandbox, and the outside world; allowing for full isolation
including the network namespace, closing the "fixed-output derivation
talks to the host over an abstract domain socket" hole for good.
Fixes CVE-2025-46416.

Step two for #496.
The idea is to allow `nix-build --arg config.allowUnfree true` do the
right thing in the future. However, that's a breaking change since
people might be relying on the ability to set `"config.allowUnfree"` as
attribute-name when auto-calling a Nix-expression.
As a first step, a warning got introduced in 2.92, the next step is now
to reject this usage in 2.94 and await feedback if any so that we can do
the change in a future Lix release.

we no longer use thread pools for querying missing derivations. this
binds queryMissing to a single thread for now, but query performance
is still greatly improved. we may want to optimize the store code in
the near future too though since queryMissing is now fully cpu bound
