Currently, the parser relies on the global experimental feature flags.
In order to properly test conditional language features, we instead need
to pass it around in the parser::State.
This means that the parser cannot cache the result of isEnabled anymore,
which wouldn't necessarily hurt performance if the function didn't
perform a linear search on the list of enabled features on every single
call. While we could simply evaluate once at the start of parsing and
cache the result in the parser state, the more sustainable solution
would be to fix `isEnabled` such that all callers may profit from the
performance improvement.

This adds a second form to the `:log` command: it now can accept a
derivation path in addition to a derivation expression. As derivation
store paths start with `/nix/store`, this is not ambiguous.

The growth of the seccomp filter in 127ee1a101
made its compilation time significant (roughly 10 milliseconds have been
measured on one machine). For this reason, it is now precompiled and cached in
the parent process so that this overhead is not hit for every single build. It
is still not optimal when going through the daemon, because compilation still
happens once per client, but it's better than before and doing it only once for
the entire daemon requires excessive crimes with the current architecture.
Fixes: lix-project/lix#461
Change-Id: I2277eaaf6bab9bd74bbbfd9861e52392a54b61a3
This is a preparation for precompiling the filter, which is done separately.
The behaviour should be unchanged for now.

The seccomp setup code was a huge chunk of conditionally compiled
platform-specific code. For this reason, it is appropriate to move it to the
platform-specific implementation file. Ideally its setup could be moved a bit
to make it happen at the same place as the Darwin restrictions, but that change
is going to be less mechanical.

This was always in the lock file and we can simply actually print it.
The test for this is a little bit silly but it should correctly
control for my daring to exercise timezone code *and* locale code in a
test, which I strongly suspect nobody dared do before.

This *should* be sound, plus or minus the amount that the terminal code
eating code is messed up already.
This is useful for testing CLI output because it will strip the escapes
enough to just shove the expected output in a file.
Change-Id: I8a9b58fafb918466ac76e9ab585fc32fb9294819
The docs page has an incorrect escape that leads to a backslash
appearing in output. Meson stuff is self-explanatory, just shortens and
simplifies a bit.

Expose an option for disabling the BDW-GC build dependency entirely. Fix the
place where one of its headers was included (unnecessarily) without proper
guarding. Finally, use this machinery to exclude BDW-GC from the ASAN builds
entirely (its usage has already been disabled due to compatibility issues
anyway), to ensure this configuration is not regressed again.

this begins a long and arduous journey to remove all result state from
Goal, to eventually drop the std::enable_shared_from_this base, and to
completely eliminate all unsynchronized modification of states of both
Goal and Worker. by the end of this we will hopefully be able to start
and reap multiple derivation builds in parallel, which should speed up
the process quite a bit (at least for short local builds, others might
not notice a large difference. the build hooks will remain a problem.)

In the SSH code, the logger was conditionally paused, but unconditionally
resumed. This was fine as long as resuming the logger was idempotent. Starting
with 0dd1d8ca1c, it isn't any more, and the
behaviour of the code in question was missed. Consequently, an assertion
failure is triggered for example when performing builds against an "SSH" store
on localhost. Fix the issue by only resuming the logger when it has actually
been paused.

we still mutate goal state to store the results of any given goal run,
but now we also have that information in Worker and could in theory do
something else with it. we could return a map of goal to goal results,
which would also let us better diagnose failures of subgoals (at all).
Change-Id: I1df956bbd9fa8cc9485fb6df32918d68dda3ff48
this is the first step towards removing all result-related mutation of
Goal state from goal implementations themselves, and into Worker state
instead. once that is done we can treat all non-const Goal fields like
private state of the goal itself, and make threading of goals possible
Change-Id: I69ff7d02a6fd91a65887c6640bfc4f5fb785b45c
once goals run on multiple threads these fields must by synchronized as
one, or we try to run build hooks to often (or worse, not often enough)

this will usually be used either directly (which is always fine) or in
Finally blocks (where it must never throw execptions). make sure that,
exceptions being handled or not, the calling wait() in Finally doesn't
cause crashes due to the Finally no-nested-exceptions-thrown assertion

The original attempt at this introduced a regression; this commit
reverts the revert and fixes the regression.
This reverts commit 3e151d4d77.
Fix to the regression:
flakeref: fix handling of `?dir=` param for flakes in subdirs
As reported in #419[1], accessing a flake in a subdir of a Git
repository fails with the previous commit[2] applied with the error
error: unsupported Git input attribute 'dir'
The problem is that the `dir`-param is inserted into the parsed URL if a
flake is fetched from the subdir of a Git repository. However, for the
fetching part this isn't even needed. The fix is to just pass `subdir`
as second argument to `FlakeRef` (which needs a `basedir` that can be
empty) and leave the parsedURL as-is.
Added a regression test to make sure we don't run into this again.

DrvInfo's constructor that only takes `EvalState` leaves everything else
empty; a DrvInfo which has no iota of information about the derivation
it represents is not useful, and was not used anywhere.

What if you could find memory bugs in Lix without really trying very
hard? I've had variously scuffed patches to do this, but this is
blocked on boost coroutines removal at this point tbh.

there are no other uses for this yet, but asking for just a subset of

If `:edit`ing a store path, don't reload repl afterwards
to avoid losing local variables: store is immutable,
so "editing" a store path is always just viewing it.

limiting CA substitutions was a rather recent addition, and it used a
dedicated counter to not interfere with regular substitutions. though
this works fine it somewhat contradicts the documentation; job limits
should apply to all kinds of substitutions, or be one limit for each.

all goals do this. it makes no sense to not notify a goal of EOF
conditions because this is the universal signal for "child done"

just update progress every time a goal has returned from work(). there
seem to be no performance penalties, and the code is much simpler now.
