This moves the original test suite for `filterANSIEscapes` into the same
file as the newer tests. There is some overlap between the old and new
tests but that doesn't hurt anything so I kept them as-is.

This teaches `filterANSIEscapes()` how to find the end of an OSC
sequence. It also keeps OSC 8 (hyperlinks) when not instructed to filter
out all escapes, just as it keeps colors.
This also relaxes the parsing of CSI escapes to find the end of the
sequence for invalid sequences, and handles better escapes that don't
start CSI or OSC.
This fixes the repl output for `:doc builtins.fetchGit`.

only dynamic derivations could produce a non-opaque drvPath. since
dynamic derivations are no longer supported we can have drvPath be
opaque at all times, simplifying downstream code significantly and
making quite a few methods unnecessary. discardOutputPath was only
called on drvPath members anyway and thus reduces to a copy, other
operations at the very least are no longer recursive. some vestige
of dynamic derivations remains in DerivedPathMap though (for now).

string context doesn't need any tests because it's never persisted or
shown to the user. getting rid of recursive string context means that
the context string parsers can be a lot simpler from here on forward.

with impure derivations gone we move on to dynamic derivations. this too
is not done in a single commit because dynamic derivations are invasive,
modifying semantics of all references to derivation output paths and all
derivation dependency calculations. removing dynamic derivations cleanly
is made significantly harder by the multiple did-you-mean-sum types, aka
"wrappers for std::variant", holding all derivation outpath information.

we don't remove the entire feature in one go to make review easier.
impure derivations are rather unintrusive on their own, at least if
we compare them to dynamic or ca derivations in general, so we will
be done with this soon. as it stands impure derivations cannot work
without ca derivations, and those we *really* want to leave behind.

If the profile inode is invalid, e.g. invalid symlink, the current
generation cannot be discovered.
Nonetheless, this should not be a reason for an assert failure, instead
of crashing, just raise an error.

Use logger in favor over print statment.
This is explicitly supported and encuraged by pytest, which also allows
for capturing logs separate from stdout calls, which is handy for when
e.g. lix code calls out to stdout to keep those differentiated from test
output

This takes the first baby steps towards resolving #765. This first
test/workflow isn't the most useful thing ever, because it doesn't
test the code path for building the manual. Still, it does a decent job
at testing the basic git workflow, and the upload functionality.

This allows debugging the errors by pinpointing the offenders, instead
of trying to blindly guess what could have possibly gone wrong.
The wording has been improved to better explain the failure.

This was an absolute nightmare to diagnose. It turns out there's a
kernel bug: poll with events = POLLHUP will receive an event for NOT
POLLHUP internally in the kernel, delete their event subscription, and
then not receive events for any HUP later. lol! lmao!!
We choose to use plain old EVFILT_READ because the watched fd can be
either a socket or a pipe and it's preferable to eat some spurious
wakeups than have separate paths for those. The alternative is using
EVFILT_SOCK, a private API that's existed for years and which netty
uses for its sockets, but that doesn't work on pipes.

it's not useful. nix-instantiate will always point to the wrong location
because "at the toplevel" is not a position we can point to. all nesting
conversions will point to strange places: the *original* definition of a
lambda value (or partial applications thereof), or nowhere at all (since
only lambda values can have their positions determined in the formatter)

this is much more useful than a frame pointing to the set but claiming
it as a function being called. if the function is actually at fault we
will now point to its attribute, although the position may be slightly
wrong if __toString was defined from set updates or builtin functions.

SSH runs the command provided to it in the user's login shell.
That's a feature and is impossible to bypass (trust me, we tried).
The previous implementation of `echo started; nix-store --stdio`
broke with shells that treat `;` differently, e.g. nushell,
which eats the output of everything but the last command in a chain.
In the more general case, this means that a sufficiently weird shell
can do _anything_ it wants to the command we pass via SSH, so
we're forced to rely on as little functionality as possible.
The subset we're hereby settling on is just "running `bash` runs bash".
We then run bash, in non-interactive mode, which gives us a somewhat
consistent environment do to things in.
This whole thing is extremely cursed, but fixing it _correctly_
requires pretty much entirely rewriting how remote stores work,
and I'm not doing that right now.
Fixes#805.

This was discussed as part of https://git.lix.systems/lix-project/lix/issues/767
with a one month long comment period.
This commit removes the recursive-nix feature from Lix. It has seen
limited usage and is difficult to stabilize, especially on non-Linux
systems where its behavior is underspecified.
Maintaining this feature complicates core work on the store, as we must
account for the potential presence of the daemon in the sandbox, adding
unnecessary complexity. Additionally, its inclusion in the
platform-independent local store creates risks for non-Linux platforms.
For more details on this removal, refer to the release note entry or the
issue entry.

We now properly shell out to the parser instead of hacking stuff
together with a regex. Stuff we get for free by doing this:
- Optional trailing semicolon
- Declaring nested attribute sets
- String identifiers, and future proofing for eventual grammar
improvements to identifiers
- Dynamic attributes

our implementation is mostly unused, completely untested, and simply
breaks when users configure connection sharing independently. we can

we generally do not want to catch or throw these. catching them to print
and discard is fine, tests are largely exempt, and cases in which we can
be certain where the exception came from are also fine to *catch*. we'll
try to never *throw* (or rethrow) these if possible though because doing
so will make it impossible to construct async traces for the exceptions.
