previously the test directory could have been left untouched before executing
a test when `init.sh` was not run - and sometimes it isn't
supposed to be run - which made the test suite highly stateful and thus
behaving surprisingly on multiple runs.
pararameterisation is not actually needed the way things are currently
set up, and it confused me when trying to understand what the code does.
all but one test sources vars-and-functions.sh, which nominally only
defines variables, but in practice is always coupled with the actual
initialisation. while the cleaner way of making this more legible would
be to source variables and initialisation separately, this would produce
a huge diff.
the change requires a few small fixes to keep the tests working:
- only create test home directory during initialisation
that vars-and-functions.sh wrote to the file system seems not write
- fix creation of the test directory
due to statefulness, the test home directory was implicitly creating
the test root, too. decoupling that made it apparent that this was
probably not intentional, and certainly confusing.
- only source vars-and-functions.sh if init.sh is not needed
there is one test case that only needs a helper function but no
initialisation side effects
- remove some unnecessary cleanups and split parts of re-used test code
there were confusing bits in how initialisation code was repurposed,
which break if trying to refactor the outer layers naively...
In streaming mode, libarchive doesn't handle symlinks in zip files
correctly. So write the entire file to disk so libarchive can access
it in random-access mode.
Fixes#10649. This was broken in cabee98152.
Make sure that `extraSandboxProfile` is set before we check whether it's
empty or not (in the `sandbox=true` case).
Also adds a test case for this.

This also reworks the Mercurial fetcher (which was still using the
old cache interface) to have two distinct cache mappings:
* A ref-to-rev mapping, which is store-independent.
* A rev-to-store-path mapping.
https://github.com/NixOS/nix/pull/10456 fixed the addition of symlink
store paths to the sandbox, but also made it so that the hardcoded
sandbox paths (like `/etc/hosts`) were now bind-mounted without
following the possible symlinks. This made these files unreadable if
there were symlinks (because the sandbox would now contain a symlink to
an unreachable file rather than the underlying file).
In particular, this broke FOD derivations on NixOS as `/etc/hosts` is a
symlink there.
Fix that by canonicalizing all these hardcoded sandbox paths before
adding them to the sandbox.
This requires moving resolveSymlinks() into SourceAccessor. Also, it
requires LocalStoreAccessor::maybeLstat() to work on parents of the
store (to avoid an error like "/nix is not in the store").
Fixes#10375.
Instead of relying on setup script to set output variables when
structured attributes are enabled, iterate over the values of an
outputs associative array.

Now that we have a few things identifying content address methods by
name, we should be consistent about it.
Move up the `parseHashAlgoOpt` for tidiness too.
Discussed this change for consistency's sake as part of #8876

This probably snuck in in a refactor using truthiness or so. The
trustedness flag was having the optional fullness checked, rather than
the actual contained trust level.
Also adds some tests.

When querying all paths in a binary cache store, the path's representation
is `<hash>-x` (where `x` is the value of `MissingName`) because the .narinfo
filenames only contain the hash.
Before cc46ea1630 this worked correctly,
because the entire path info was read and the path from this
representation was printed, i.e. in the form `<hash>-<name>`. Since then
however, the direct result from `queryAllValidPaths()` was used as `path`.
Added a regression test to make sure the behavior remains correct.
