Lily Foster 92c7d33ee3 Sort attrs from tables in fromTOML
This was dropped in 10a8b5d for the migration from cpptoml to toml11 but
seems to be necessary for the attrsets to work correctly.

flake.cc: computeLocks: Only verify overrides when they could change
When we check for disappeared overrides, we can get "false positives"
for follows and overrides which are defined in the dependencies of the
flake we are locking, since they are not parsed by
parseFlakeInputs. However, at that point we already know that the
overrides couldn't have possible been changed if the input itself
hasn't changed (since we check that oldLock->originalRef == *input.ref
for the input's parent). So, to prevent this, only perform this check
when it was possible that the flake changed (e.g. the flake we're
locking, or a new input, or the input has changed and mustRefetch ==
true).

This makes sure that values parsed from TOML have a proper size. Using
e.g. `double` caused issues on i686 where the size of `double` (32bit)
was too small to accommodate some values.

pennae 09b245690a bulk-allocate Value instances in the evaluator
calling GC_malloc for each value is significantly more expensive than
allocating a bunch of values at once with GC_malloc_many. "a bunch" here
is a GC block size, ie 16KiB or less.

this gives a 1.5% performance boost when evaluating our nixos system.

nix eval --raw --impure --expr 'with import <nixpkgs/nixos> {}; system'

This is intentionally crude and undocumented as it’s only meant to be a

Better diagnostics if no valid signature found
I downloaded Nix tonight, and immediately broke it by accidentally removing the default binary caching.
After figuring this out, I also failed to fix it properly, due to using the wrong key for Nix's default binary cache

If the diagnostic message would have been clearer about what/where a "signature" for a "substituter" is + comes from, it probably would have saved me a few hours.
Maybe we can save other noobs the same pain?

RunPager: restore stdout upon pager exit
Before this change, stdout was closed after the pager exits. This is
fine for non-interactive commands where we want to exit right after

this breaks the output after we quit the pager.

Keep the initial stdout fd as part of RunPager, and restore it in
RunPager::~RunPager using dup2.

Flakes: computeLocks: pass correct LockParent when reusing oldLock
Previously, when we were attempting to reuse the old lockfile
information in the computeLocks function, we have passed the parent of
the current input to the next computeLocks call. This was incorrect,
since the follows are resolved relative to the parent. This caused
issues when we tried to reuse oldLock but couldn't for some
reason (read: mustRefetch is true), in that case the follows were
resolved incorrectly.

Fix this by passing the correct parent, and adding some tests to
prevent this particular regression from happening again.

No matter what, we need to resize the buffer to not have any scratch

from it's initial value.

Before, we forgot to resize in the EOF case with the break. Yes, we know
we didn't recieve any data in that case, but we still have the scatch
space to undo.

Don't move the arguments of the primOp
Moving arguments of the primOp into the registration structure makes it
impossible to initialize a second EvalState with the correct primOp
registration. It will end up registering all those "RegisterPrimOp"'s
with an arity of zero on all but the 2nd instance of the EvalState.

Not moving the memory will add a tiny bit of memory overhead during the
eval since we need a copy of all the argument lists of all the primOp's.
The overhead shouldn't be too bad as it is static (based on the amonut
of registered operations) and only occurs once during the interpreter
startup.

We let DISPLAY (X11) through, so we should let the Wayland equivalents
through as well.  Similarly, we let HOME through, so it should be okay
to allow XDG_RUNTIME_DIR (which is needed for connecting to Wayland
with WAYLAND_DISPLAY) through as well.  Otherwise graphical
applications will either fall back to X11 (if they support it), or
just not work (if they don't).

Sergei Trofimovich edfc5b2f12 ca-specific-schema.sql: add index on RealisationsRefs(referrer) and (outputPath)
For a typical desktop system (~2K packages) we can easily get 100K
entries in RealisationsRefs. Without indices query for RealisationsRefs
requires linear scan.

RealisationsRefs(referrer)
--------------------------

Inefficiency is seen as a 100% CPU load of nix-daemon for the following
scenario:

    $ nix edit -f . bash # add unused environment variable, like FOO="1"
    # populate RealisationsRefs, build fresh system
    $ nix build -f nixos system --arg config '{ contentAddressedByDefault = true; }'
    $ nix edit -f . bash # add unused environment variable, like FOO="2"
    $ time nix build -f nixos system --arg config '{ contentAddressedByDefault = true; }'

In this case `bash `will be rebuilt a few times and then rest of CPU
time is spent on scanning RealisationsRefs table (about 5 CPU-minutes
on my machine).

Before the change:

    $ time nix build -f nixos system ... # step 4 above
    real    34m3,613s
    user    0m5,232s
    sys     0m0,758s

Of all this time about 29.5 minutes are taken by nix-daemon's CPU time.

After the change:

    $ time nix build -f nixos system ... # step 4 above
    real    4m50,061s
    user    0m5,038s
    sys     0m0,677s

Of all this time about 1 minute is taken by nix-daemon's CPU time.
Most of the time is spent polling for non-existent realisations on
cache-nixos.org.

Realisations(outputPath)
------------------------

After running CA system for two weeks I got ~1M entries in Realisations
table. `nix-collect-garbage` became very slow (seemingly 100 path deletions
per second). It happens due to a slow cascading delete from Realisations
triggered by deletion from ValidPaths.

The fix is to add an index on primary key from ValidPaths(id) that
triggers cascading deletions.

Before the change:
    $ time nix-collect-garbage -d --max-freed 100G
    <interrupted before finish, took too long>
    real    23m32.411s
    user    17m49.679s
    sys     4m50.609s

Most of time was spent in re-scanning Realisations table on each path deletion.

After the change:
    $ time nix-collect-garbage -d --max-freed 100G

    real    8m43.226s
    user    6m16.317s
    sys     1m40.188s

Time is spent scanning sqlite indices and in kernel when unlinking directories.

Eelco Dolstra 81e7c40264 Optimize primop calls
We now parse function applications as a vector of arguments rather
than as a chain of binary applications, e.g. 'substring 1 2 "foo"' is
parsed as

  ExprCall { .fun = <substring>, .args = [ <1>, <2>, <"foo"> ] }

rather than

  ExprApp (ExprApp (ExprApp <substring> <1>) <2>) <"foo">

This allows primops to be called immediately (if enough arguments are
supplied) without having to allocate intermediate tPrimOpApp values.

On

  $ nix-instantiate --dry-run '<nixpkgs/nixos/release-combined.nix>' -A nixos.tests.simple.x86_64-linux

this gives a substantial performance improvement:

  user CPU time:      median =      0.9209  mean =      0.9218  stddev =      0.0073  min =      0.9086  max =      0.9340  [rejected, p=0.00000, Δ=-0.21433±0.00677]
  elapsed time:       median =      1.0585  mean =      1.0584  stddev =      0.0024  min =      1.0523  max =      1.0623  [rejected, p=0.00000, Δ=-0.20594±0.00236]

because it reduces the number of tPrimOpApp allocations from 551990 to
42534 (i.e. only small minority of primop calls are partially
applied) which in turn reduces time spent in the garbage collector.

regnat af99941279 Make experimental-features a proper type
Rather than having them plain strings scattered through the whole
codebase, create an enum containing all the known experimental features.

This means that
- Nix can now `warn` when an unkwown experimental feature is passed
  (making it much nicer to spot typos and spot deprecated features)
- It’s now easy to remove a feature altogether (once the feature isn’t
  experimental anymore or is dropped) by just removing the field for the
  enum and letting the compiler point us to all the now invalid usages
  of it.

Restore parent mount namespace in restoreProcessContext
This ensures any started processes can't write to /nix/store (except
during builds). This partially reverts 01d07b1e, which happened because
of #2646.

The problem was only happening after nix downloads anything, causing
me to suspect the download thread. The problem turns out to be:
"A  process  can't  join a new mount namespace if it is sharing
filesystem-related attributes with another process", in this case this
process is the curl thread.

Ideally, we might kill it before spawning the shell process, but it's
inside a static variable in the getFileTransfer() function. So
instead, stop it from sharing FS state using unshare(). A strategy
such as the one from #5057 (single-threaded chroot helper binary) is
also very much on the table.

Fixes #4337.

nix repl: properly deal with interruptions
When I stop a download with Ctrl-C in a `nix repl` of a flake, the REPL
refuses to do any other downloads:

    nix-repl> builtins.getFlake "nix-serve"
    [0.0 MiB DL] downloading 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca41 error: download of 'e9828a9e01' was interrupted
    [0.0 MiB DL]
    nix-repl> builtins.getFlake "nix-serve"
    error: interrupted by the user
    [0.0 MiB DL]

To fix this issue, two changes were necessary:

* Reset the global `_isInterrupted` variable: only because a single
  operation was aborted, it should still be possible to continue the
  session.
* Recreate a `fileTransfer`-instance if the current one was shut down by
  an abort.

Andreas Rammhold cae41eebff libexpr: remove matchAttrs boolean from ExprLambda
The boolean is only used to determine if the formals are set to a
non-null pointer in all our cases. We can get rid of that allocation and
instead just compare the pointer value with NULL. Saving up to
sizeof(bool) + platform specific alignment per ExprLambda instace.
Probably not a lot of memory but perhaps a few kilobyte with nixpkgs?

This also gets rid of a potential issue with dereferencing formals based on
the value of the boolean that didn't have to be aligned with the formals
pointer but was in all our cases.

I had started the trend of doing `std::visit` by value (because a type
error once mislead me into thinking that was the only form that
existed). While the optomizer in principle should be able to deal with
extra coppying or extra indirection once the lambdas inlined, sticking
with by reference is the conventional default. I hope this might even
improve performance.

libexpr: throw a more helpful eval-error if a builtin is not available due to a missing feature-flag
I found it somewhat confusing to have an error like

    error: attribute 'getFlake' missing

if the required experimental-feature (`flakes`) is not enabled. Instead,
I'd expect Nix to throw an error just like it's the case when using e.g. `nix
flake` without `flakes` being enabled.

With this change, the error looks like this:

    $ nix-instantiate -E 'builtins.getFlake "nixpkgs"'
    error: Cannot call 'builtins.getFlake' because experimental Nix feature 'flakes' is disabled. You can enable it via '--extra-experimental-features flakes'.

           at «string»:1:1:

                1| builtins.getFlake "nixpkgs"
                 | ^

I didn't use `settings.requireExperimentalFeature` here on purpose
because this doesn't contain a position. Also, it doesn't seem as if we
need to catch the error and check for the missing feature here since
this already happens at evaluation time.

build: also throw hash-mismatch errors if `buildMode == bmCheck`

build: also throw hash-mismatch errors if buildMode == bmCheck
This actually bit me quite recently in `nixpkgs` because I assumed that
`nix-build --check` would also error out if hashes don't match anymore[1]
and so I wrongly assumed that I couldn't reproduce the mismatch error.

The fix is rather simple, during the output registration a so-called
`delayedException` is instantiated e.g. if a FOD hash-mismatch occurs.
However, in case of `nix-build --check` (or `--rebuild` in case of `nix
build`), the code-path where this exception is thrown will never be
reached.

By adding that check to the if-clause that causes an early exit in case
of `bmCheck`, the issue is gone. Also added a (previously failing)
test-case to demonstrate the problem.

[1] https://github.com/NixOS/nixpkgs/pull/139238, the underlying issue
    was that `nix-prefetch-git` returns different hashes than `fetchgit`
    because the latter one fetches submodules by default.

Eelco Dolstra ea9df6fe51 Shut down write side before draining the read side
This is important if the remote side *does* execute
nix-store/nix-daemon successfully, but stdout is polluted
(e.g. because the remote user's bashrc script prints something to
stdout). In that case we have to shutdown the write side to force the
remote nix process to exit.

Geoff Reedy 9d67332e4b Better eval error locations for interpolation and +
Previously, type or coercion errors for string interpolation, path
interpolation, and plus expressions were always reported at the
beginning of the outer expression. This leads to confusing evaluation
error messages making it hard to accurately diagnose and then fix the
error.

For example, errors were reported as follows.

```
cannot coerce an integer to a string
1| let foo = 7; in "bar" + foo
 |                 ^

cannot add a string to an integer
1| let foo = "bar"; in 4 + foo
 |                     ^

cannot coerce an integer to a string
1| let foo = 7; in "x${foo}"
 |                  ^
```

This commit changes the ExprConcatStrings expression vector to store a
sequence of expressions *and* their expansion locations so that error
locations can be reported accurately. For interpolation, the error is
reported at the beginning of the entire `${foo}`, not at the beginning
of `foo` because I thought this was slightly clearer. The previous
errors are now reported as:

```
cannot coerce an integer to a string
1| let foo = 7; in "bar" + foo
 |                         ^

cannot add a string to an integer
1| let foo = "bar"; in 4 + foo
 |                         ^

cannot coerce an integer to a string
1| let foo = 7; in "x${foo}"
 |                   ^
```

The error is reported at this kind of precise location even for
multi-line indented strings.

This probably helps with at least some of the cases mentioned in #561
