eldritch horrors b22f2bc8e9 libstore: use http for exceptionAbortsDownload tests
file:// urls are no longer handled by curl itself, and this is supposed
to test the curl wrapper. use http to force the wrapper to be involved.

eldritch horrors 5d02800e57 libstore: do not retry FileTransfer uploads
this only ever worked for empty uploads, and there it worked only by
complete accident: curl was asked to send more data than the wrapper
would provide, which curl would not like and report as an error. the
error would cause a retry with even less data to send, until finally
failing by running into the retry limit. let's just forbid all this.

Lily Ballard 3c8096e5cb feat: Add temp-dir setting
This adds a new temp-dir setting for controlling the temporary directory
without having to change the TMPDIR env var. This can be used to e.g.
use a path on a case-sensitive store on macOS for temporary files
without changing the TMPDIR var used by interactive shells or commands
invoked with `nix run`.

This also stops unsetting `TMPDIR` on darwin when the env var value
starts with `/var/folders/`, preferring instead to just do the check
when reading `TMPDIR`. This way the inherited `TMPDIR` env var is
preserved for child processes (such as interactive shells).

As a side effect this changes the behavior of `nix-build -o ''` to act
like `nix-build --no-out-link` instead of failing with an error caused
by trying to create a symlink at the cwd.

raito 6e2349d2e1 Revert "Reject weak hash algorithms as SRIs, and warn in any other cases"
This reverts commit 02c35ea9df.

Reason for revert: this code path is also used for `Input::getRev()`, i.e. flakes VCS revision validation, which, in the case of Git, are using SHA1.
As a result, this cause too much noise due to SHA1 revisions in Flakes.

eldritch horrors 4ae6fb5a8f libstore: pause only stalling transfers
don't pause the entire curl thread. we have multiple consumer threads
after all, not just one, so stalling all of them is likely not great.

note that libcurl advises against using transfer pauses if compressed
encodings are allowed and automatically decoded. this should not lead
to problems in practice because our data is usually not compressed to
such a degree that curl buffering *uncompressed* data matters. should
this cause problems we can reintroduce the whole-thread pause, but we
will probably get away with this until the entire file transfer class
is made kj::Promise-using async (and *then* curl can be hardpaused if
it cannot get rid of its data, solving the problem once and for all).

it's just a uri and some headers now. those can be function arguments
with no loss of clarity. *actual* additional arguments, for example a
TLS context with additional certificates, could be added on a new and
improved FileTransfer class that carries not just a backend reference
but some real, visible context for its transfers. curl not being very
multi-threading-friendly when using multi handles will make sharing a
bit hard anyway once we drop the single global download worker thread

Linus Heckemann e55cd3beea libutil: handle json builder log messages with unexpected format
Before this change, expressions like:

with import <nixpkgs> {};
runCommand "foo" {} ''
  echo '@nix {}' >&$NIX_LOG_FD
''

would result in Lix crashing, because accessing nonexistent fields of
a JSON object throws an exception.

Rather than handling each field individually, we just catch JSON
exceptions wholesale. Since these log messages are an unusual
circumstance, log a warning when this happens.

Fixes #544.

jade c1f4c60bc2 nix-shell: stop using dynamic format strings!!
This was always a terrible idea independently of whether it crashes.
Stop doing it!

This commit was verified by running nix-shell on a trivial derivation
with --debug --verbose to get the vomit-level output of the shell rc
file and then diffing it before/after this change. I have reasonable
confidence it did not regress anything, though this code is genuinely
really hard to follow (which is a second reason that I split it into two
fmt calls).

Maximilian Bosch 4682e40183 ssh-ng: better way to keep SSH errors visible
A better fix than in 104448e75d, hence a
revert + the fix.

It turns out that this commit has the side-effect that when having e.g.
`StrictHostKeyChecking=accept-new` for a remote builder, the warnings à la

    Warning: Permanently added 'builder' (ED25519) to the list of known hosts.

actually end up in the derivation's log whereas hostkey verification
errors don't, but only in the stderr of the `nix-build` invocation
(which was the motivation for the patch).

This change writes the stderr from the build-hook to

* the daemon's stderr, so that the SSH errors appear in the journal
  (which was the case before 104448e75d)
* the client's stderr, as a log message
* NOT to the drv log (this is handled via `handleJSONLogMessage`)

I tried to fix the issue for legacy-ssh as well, but failed and
ultimately decided to not bother.

I know that we'll sooner or later replace the entire component, however
this is the part of the patch I have working for a while, so I figured I
might still submit it for the time being.

jade 822997bd34 libstore: ban unpacking case hacked filenames from NARs
There is absolutely no good reason these should show up in NARs besides

such a NAR will cause its repacking to be wrong on systems with case
hack enabled.

jade 3571817e3a testsuite: add a NAR generator with some evil NARs
This also rewrites a lot of the command handling in the fixtures
library, since we want to more precisely control which way that the nix
store is set up in the tests, rather than the previous method of
renaming /nix/store to some temp dir (which allows builds but does not
allow any /nix/store paths or stability across runs, which is a
significant issue for snapshot testing).

It uses a builder to reduce the amount of state carelessly thrown
around.

The evil NARs are inspired by CVE-2024-45593
(https://github.com/NixOS/nix/security/advisories/GHSA-h4vv-h3jq-v493).

No bugs were found in this endeavor.
