eldritch horrors 0b9a72524a filetransfer: {up,down}load -> transfer
even the transfer function is not all that necessary since there aren't
that many users, but we'll keep it for now. we could've kept both names
but we also kind of want to use `download` for something else very soon

jade c22a7f50cb libstore: refuse to serialise ancient protocols
We don't want to deal with these at all, let's stop doing so.

(marking this one as the fix commit since its immediate predecessors
aren't the complete fix)

The UnkeyedValidPathInfo test was testing an ancient version but not the
current version. Doesn't make much sense to me.

jade 533d469875 Revert "tests/filetransfer: reënable on Darwin"
This reverts commit 285bc67318.

Reason for revert: lix-project/lix#364

For some reason this broke `main` even though the change we are reverting passed CI! Mysterious, haunted, etc. Needs more debugging, let's turn it off for now.

jade 285bc67318 tests/filetransfer: reënable on Darwin
Since we put __darwinAllowLocalNetworking in our derivation in
I752b81c85ebeaab4e582ac01c239d69d65580f37, this stuff will just work
fine. I checked our derivation works on the darwin community builder.

eldritch horrors dd4a2c1759 libstore: fix http abuses no longer working
while refactoring the curl wrapper we inadvertently broken the immutable
flake protocol, because the immutable flake protocol accumulates headers
across the entire redirect chain instead of using only the headers given
in the final response of the chain. this is a problem because Some Known
Providers Of Flake Infrastructure set rel=immutable link headers only in
the penultimate entry of the redirect chain, and curl does not regard it
as worth returning to us via its response header enumeration mechanisms.

derived-path: refuse built derived path with a non-derivation base
Example: /nix/store/dr53sp25hyfsnzjpm8mh3r3y36vrw3ng-neovim-0.9.5^out

This is nonsensical since selecting outputs can only be done for a
buildable derivation, not for a realised store path. The build worker
side of things ends up crashing with an assertion when trying to handle
such malformed paths.

filetransfer: unit test content-encoding handling
Very basic behavior test to ensure that gzip data gets internally
decompressed by the file transfer pipeline.

Change a std::string_view return value in the test harness to
std::string. I wouldn't call myself a C++ beginner and I still managed
to shoot myself in the foot like three times with the lifetime
managements there (e.g. [&] { return an_std_string; } ends up with a
dangling string_view!).

eldritch horrors 6b08138929 filetransfer: abort transfer on receiver exception
not doing this will cause transfers that had their readers disappear to
linger. with lingering transfers the curl thread can't shut down, which
will cause nix itself to not shut down until the transfer finishes some
other way (most likely network timeouts). also add a new test for this.

Robert Hensing b7ce11c97d Disallow store path names that are . or .. (plus opt. -)
As discussed in the maintainer meeting on 2024-01-29.

Mainly this is to avoid a situation where the name is parsed and
treated as a file name, mostly to protect users.
.-* and ..-* are also considered invalid because they might strip
on that separator to remove versions. Doesn't really work, but that's
what we decided, and I won't argue with it, because .-* probably
doesn't seem to have a real world application anyway.
We do still permit a 1-character name that's just "-", which still
poses a similar risk in such a situation. We can't start disallowing
trailing -, because a non-zero number of users will need it and we've
seen how annoying and painful such a change is.

What matters most is preventing a situation where . or .. can be
injected, and to just get this done.

* various default-case-missing complaints

  deliberate.
* an instance of <https://clang.llvm.org/extra/clang-tidy/checks/bugprone/move-forwarding-reference.html>
* bugprone-not-null-terminated-result on handing a string to curl in
  chunks of bytes. our usage is fine.
* reassigning a unique_ptr by CRIMES instead of using release(), then
  using release() and ignoring the result. wild. let's use release() for
  its intended purpose.

eldritch horrors 96a3683308 Ban building Nix with NDEBUG
When reviewing old PRs, I found that #9997 adds some code to ensure one
particular assert is always present. But, removing asserts isn't
something we do in our own release builds either in the flake here or in
nixpkgs, and is plainly a bad idea that increases support burden,
especially if other distros make bad choices of build flags in their Nix
packaging.

For context, the assert macro in the C standard is defined to do nothing
if NDEBUG is set.

There is no way in our build system to set -DNDEBUG without manually
adding it to CFLAGS, so this is simply a configuration we do not use.
Let's ban it at compile time.

I put this preprocessor directive in src/libutil.cc because it is not
obvious where else to put it, and it seems like the most logical file
since you are not getting a usable nix without it.

John Ericson f7f37035c8 Move tests to separate directories, and document
Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:

- We have to be careful that wildcards don't end up with tests being
  built as part of Nix proper, or test headers being installed as part
  of Nix proper.

- Tests in libraries but not executables is not right:

  - It means each executable runs the previous unit tests again, because
    it needs the libraries.

  - It doesn't work right on Windows, which doesn't want you to load a
    DLL just for the side global variable . It could be made to work
    with the dlopen equivalent, but that's gross!

This reorg solves these problems.

There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.
