This part of the store API needs to carry a handle to the log sink
from now on, so that it can be passed in as appropriate from the gRPC
handlers.
In all places where there is no such handler available at the moment,
the discarding log sink has been inserted. This can be used as a
convenient grep target in the future.

We have decided that leaking memory is a better fate than random,
non-debuggable memory corruption. Future CLs will begin changing
various fields to std::unique_ptr and std::shared_ptr.
It turns out that disabling the GC does not have disasterous impact.
The Nix evaluator only runs on the client CLI, never in any long-
running process. Even the REPL does not leak too badly under this
change, because it uses one EvalState for the duration of the REPL.
Building an explicitly tracing garbage collector is likely in the
future of this project, but that giant amount of work cannot be
done under a nix evaluator that is constantly crashing. We need to
restore development velocity here, and this is the best way we've
figured out to do it.

This also replaces the flag parsing logic with absl::flags. This
causes a behaviour change for --help, which no longer tries to display
a man page but instead shows the actual command-line help.
Note: This binary no longer links to the Boehm GC.

Only libexpr depends on the garbage collector, specifically only
instantiations of EvalState actually require the GC to be initialised.
Rather than always starting it for the whole program, even if it is
not needed, this change moves the GC initialisation into libexpr,
guarded by absl::call_once.
This should make it possible to run the nix daemon without the garbage
collector interfering, granted that things are correcty separated and
the daemon does not actually invoke the evaluator.
Based on my investigation so far, the daemon logic itself does not
require libexpr to be present at all - so I think it is safe - but the
current monobinary might have some tricks up its sleeve that will
cause problems for us. We can deal with those if they arise.

Add ironclad, a common lisp library for cryptography. This is a huge
library with a lot of moving parts - probably most notable here is that
I've had to turn off compiling with `:ironclad-assembly`, as it was
causing an infinite loop in the compiler due to
https://github.com/sharplispers/ironclad/blob/master/src/opt/sbcl/cpu-features.lisp#L9-L10,
a mutually self-recursive function that looks like:
(defun aes-ni-support-p ()
(aes-ni-support-p))
Without knowing much about how sbcl handles native-compiled assembly, it
seems like this definition should actually be skipped entirely, due to
it being defined as a `defknown` in `fndb.lisp`:
(defknown ironclad::aes-ni-support-p
()
(boolean)
(any)
:overwrite-fndb-silently t)
But something about how we're compiling things was causing that not to
happen, and the infinite recursion caused the compiler to hang. This
should be fixed at some point, but given I only need this library as a
transitive dependency down a level I'm not going to attempt to do so now.

* A handful of tests have been disabled as they are causing failures

reorderings which are fine because this is all provisional and not

A couple things to note
- I implemented a couple constructors for nix classes that initialize
themselves based on their proto variants, which felt nice and didn't
end up causing any issues.
- I've made the conversions between the enum types in nix and in proto
explicit via switch statements rather than using a static_cast, out of
an abundance of caution that the error would get mismatched in the
future and we'd convert the wrong thing to the wrong thing - this is
verbose, but exceptionally future proof.

This change does away with the previous special-casing of lists of
certain element sizes, and the use of raw C-style arrays.
Lists are now backed by a std::vector of nix::Value*, which uses the
traceable GC allocator.
This change is unfortunately quite noisy because the accessor methods
were updated/removed accordingly, so all callsites of Nix-related
lists have changed.
For some operations in primops.cc where keeping the previous code
structure would have been more difficult with a "proper" vector, the
implementation has been replaced with std::vector methods. For
example, list concatenation now uses appropriate range inserts.
Anecdotally the performance of this is about equal, to even slightly
better, than the previous implementation.
All language tests pass and the depot paths I've used for testing
still evaluate.

Going forward we will trial implementations of attribute sets backed

To aid in making the decision of where to (currently just statically)
use a vector or btree as the backing implementation, add an extra
constructor argument to Bindings::NewGC for a capacity, and use
a (currently hardcoded at 32, for no good reason other than it felt like
a reasonable number) pivot to switch between our possible backing
implementations. Then, update all the call sites where it feels
reasonable that we know the capacity statically to *pass* that capacity

Add an alternative impl of the now-abstract Bindings base class that is
backed by a std::vector, somewhat similar but stylistically a little
superior to the array-backed implementation in upstream nix. The
underlying iterator type in BindingsIterator is now backed by a
std::variant that we std::visit an overload over in order to implement
the various bits of the iterator interface.

To pave the way for the thing we want to do eventually which is use a
linear-time array for bindings (aka attribute sets) that are statically
known to be small enough to get a performance benefit from doing so,
make the Bindings class abstract, and define a BTreeBindings class that
inherits from it and is (currently always) returned from the static
initializer. The idea is that we'll have an ArrayBindings class as well
later that we can dispatch to conditionally based on an optional
"capacity" parameter or something like that.
There was some difficulty here in getting the iterator to work - the
approach we settled on ended up making a concrete BindingsIterator class
which will wrap a std::variant of either a btree iterator or something
else later, but right now just wraps a btree iterator.

nix:AttrName was one of the few classes that relied on the default
constructor of nix::Symbol (which I am trying to remove in a separate
change).
The class essentially represents the name of an attribute in a set,
which is either just a string expression or a dynamically evaluated
expression (e.g. string interpolation).
Previously it would be constructed by only setting one of the fields
and defaulting the other, now it is an explicit std::variant.
Note that there are several code paths where not all eventualities are
handled and this code is bug-for-bug compatible with those, except
that unknown conditions (which should never work) are now throwing
instead of silently doing ... something.
The language tests pass with this change, and the depot derivations
that I tested with evaluated successfully.

Original fault description by puck:
I suspect I found the issue: The Nix Command structs are stored on the
heap (using ref<T>, a wrapper around std::shared_ptr<T>), which means
that any pointers that the NixRepl struct contains are eligible to be
reaped by the GC. This includes, but is not limited to, the Env
pointer, which seems to cause most of the random segfaults, or random
other values in the environment, which seems to be what @arianvp
experienced too.

The protocol definition is basically a big enum with the signatures of

The definitions in this file are slowly reversed from these implicit
signatures, and are likely to contain an error or two which will be
weeded out when this is taken into use.

This adds support for overriding the detected languages based on the
filename - we assume here that rules.pl will always map to a Prolog
file.
I could've overridden the entire default language to Prolog, since it's
unlikely that we'll have any Perl here, but given the relative
popularity of the two languages I opted to just override the file we
know we'll have (because it's used by Gerrit itself).

This uses the actual Bazel build, using a variety of tricks and hacks to
make it actually work.
Bazel really wants to download linux binaries from the internet and run
them. In lieu of trying to fix the build system to not do this, we
instead put bazel inside an FHS environment, which allows the binaries
to find their dependencies.
We also have to patch a few things:
* We use build --nobuild instead of fetch, so we only fetch the
dependencies we actually need for the build and not, say, Windows
binaries.
* We don't remove rules_cc, because we need it as an external
dependency, not bundled.
* We do some manual fixes on the cache before packing, because we need
to remove some in-tree sources (so they don't cause the hash to break,
since the hashes differ each time they're generated), and also remove
some extraneous files.
* We explicitly turn off the repository and disk caches, because the
.bazelrc at the root of the Gerrit tree turns them on, with paths
pointing into the user's home directory.
* detzip is used instead of the zip binary for packing bower_components
into an archive. detzip doesn't create entries for directories, and
also doesn't store most metadata (timestamps, etc.), and uses store
(i.e. uncompressed) compression only. It also sorts the file tree
before writing them into the file.

Clang treats function-like macros "correctly", in that, per the C11 spec:
"Each subsequent instance of the function-like macro name followed by a (
[...] is replaced by the replacement list [...]".
Additionally, fprintf is also permitted to be defined as a function-like
macro rather than as a true function: "Any function declared in a header
may be additionally implemented as a function-like macro defined in the
header [...]". The specification then suggests surrounding the name of the
function in parens to avoid this, which is the technique we use here to avoid
the function-like macro being invoked.
The other fix here is to use uintptr_t for some arithmetic, since Git
is expecting an int as the value here and not a pointer.
Having a colon in the path may cause issues, and having the hash
function indicated isn't actually necessary. We now verify the path
format in the tests to prevent regressions.

Completes the switch from Meson to CMake for the core build system in
Nix.
Meson was added originally because someone else had already done the
work for integrating it in Nix and it was an upgrade from the previous
setup.
However over time it became clear that Meson is not quite mature
enough for projects like Nix that have occasionally peculiar
configuration constraints.
Some issues encountered with Meson (some of these are due to the Meson
setup in Nix):
* Difficulty with generating correct compile_commands.json for
external tools like clangd
* Difficulty linking to libc++ when using clang
* Ugly shell invocations for certain parts of the build system (I want
these to be gone!!!)
This CMake setup mimics the Meson configuration, but there are some
differences (some temporary):
* headers are now included separately for each library (see a previous
commit that changes includes appropriately)
* autoheaders-style configuration is currently hardcoded. Before
blindly copying this I want to evaluate how much of it actually exists
for portability concerns that I don't have (such as support for OS
X).
* Nix is built with libc++ by default.
* [libstore] SQL schema is now inlined via a generated header, not an
included string literal
Abseil is still built as part of this build, rather than an external
dependency, because it chokes on differently configured compiler
invocations.
Note that because of the move to libc++ an unwanted behaviour is
introduced: glog log messages no longer have a body. I have yet to
debug what is going on there.
Previously all includes were anchored in one global mess of header
files. This moves the includes into filesystem "namespaces" (if you
will) for each sub-package of Nix.
Note: This commit does not introduce the relevant build system changes.
This function was a custom (and inefficient in the case of
single-character delimiters) string splitter which was used all over
the codebase. Abseil provides an appropriate replacement function.
Replaces these functions with corresponding functions from Abseil,
namely absl::StripAsciiWhitespace and absl::SimpleAtoi.
In the course of doing this some minor things I encountered along the
way were also refactored.
This also changes the signatures of the various custom readFile
functions to use absl::string_view types.
It is considered bad form to use things from includes in headers, as
these directives propagate to everywhere else and can make it
confusing.
types.hh (which is includes almost literally everywhere) had some of
these directives, which this commit removes.
Suppose I have a path /nix/store/[hash]-[name]/a/a/a/a/a/[...]/a,
long enough that everything after "/nix/store/" is longer than 4096
(MAX_PATH) bytes.
Nix will happily allow such a path to be inserted into the store,
because it doesn't look at all the nested structure. It just cares
about the /nix/store/[hash]-[name] part. But, when the path is deleted,
we encounter a problem. Nix will move the path to /nix/store/trash, but
then when it's trying to recursively delete the trash directory, it will
at some point try to unlink
/nix/store/trash/[hash]-[name]/a/a/a/a/a/[...]/a. This will fail,
because the path is too long. After this has failed, any store deletion
operation will never work again, because Nix needs to delete the trash
directory before recreating it to move new things to it. (I assume this
is because otherwise a path being deleted could already exist in the
trash, and then moving it would fail.)
This means that if I can trick somebody into just fetching a tarball
containing a path of the right length, they won't be able to delete
store paths or garbage collect ever again, until the offending path is
manually removed from /nix/store/trash. (And even fixing this manually
is quite difficult if you don't understand the issue, because the
absolute path that Nix says it failed to remove is also too long for
rm(1).)
This patch fixes the issue by making Nix's recursive delete operation
use unlinkat(2). This function takes a relative path and a directory
file descriptor. We ensure that the relative path is always just the
name of the directory entry, and therefore its length will never exceed
255 bytes. This means that it will never even come close to AX_PATH,
and Nix will therefore be able to handle removing arbitrarily deep
directory hierachies.
Since the directory file descriptor is used for recursion after being
used in readDirectory, I made a variant of readDirectory that takes an
already open directory stream, to avoid the directory being opened
multiple times. As we have seen from this issue, the less we have to
interact with paths, the better, and so it's good to reuse file
descriptors where possible.
I left _deletePath as succeeding even if the parent directory doesn't
exist, even though that feels wrong to me, because without that early
return, the linux-sandbox test failed.

Replaces the previous implementations which performed sorting with one
that instead walks through the map (which is already sorted) and
yields values from it.
This fixes a handful of language tests because the previous
implementation did not actually yield useful values on the new implementation.
In the change to the backing structure of attribute sets, the
requirement to manually balance the capacity of the structure went
away.
This is a) because Abseil's data structures manage this on their own,
and b) because the new Bindings class is allocated using `new (GC)`
rather than writing into a predefined memory area.
As part of this change functions related to the capacity were
deprecated and set to 0 values, which in turn caused the creation of
new attribute sets to return the same (mutable!) default value in
various cases, leading to "side effects" that caused evaluation
failures.
FWIW, I'm not sure if this optimisation had noticeable performance
impact, but while untangling libexpr it definitely doesn't help trying
to follow what it's doing - so bye, bye!
This wrapper derivation (which assumes that the depot is available at
~/depot) can be used to actually get clangd working with
//third_party/nix.
In my setup I can launch this with M-x eglot, followed by
env
CLANGD_FLAGS='--compile-commands-dir=/home/tazjin/projects/nix-build'
nix-shell -A third_party.nix --run 'nix-clangd' /home/tazjin/depot
This is closer to bug-for-bug compatibility with the previous version,
which would put new elements at the end of the array and (due to the
linear scan) return previous ones.
Emacs is currently subtly broken on nixos-unstable, but I don't care
about debugging that.
To work around it, this reintroduces the NixOS stable channel (20.03)
but as a separate attribute set from which attributes like Emacs can be
picked into //third_party.
The new attribute set API uses the iterators of the btree_map
directly. This requires changes in various files because the internals
of libexpr are very entangled.
This code runs and compiles, but there is a bug causing empty
attribute sets to be assigned incorrectly.
Instead of doing some sort of inline merge-sort of the two attribute
sets, use the attribute sets merge function.
This commit alone does not build and is not supposed to.
This is the first step towards replacing the implementation of
attribute sets with an absl::btree_map.
Currently many access are done using array offsets and pointer
arithmetic, so this change is currently causing Nix to fail in various
ways.
Replaces most uses of `string` with `std::string`.
This came up because I removed the "types.hh" import from
"symbol-table.hh", which percolated through a bunch of files where
`string` was suddenly no longer defined ... *sigh*
This replaces the previous use of std::unordered_set with
absl::node_hash_set.
This type was chosen because the current implementation requires
pointer stability.
This does not yet touch the 'Attr' struct.
As a bonus, the implementation of the SymbolTable struct is now
consolidated into a single header/implementation file pair.
Meson is unable to use CMake in Nix to determine the internal
structure of the Abseil libraries.
This commit adds an explicit list of most of the Abseil targets that
are relevant (so far) and bundles them into a list that is linked
together.
cmake automatically runs a configure hook which breaks the build,
since this isn't actually a cmake project. This hook is now disabled.
Additionally Abseil's sources are linked to an absolute derivation
path when the build launches, as opposed to the relative path used for
development builds.
This applies the modernization fixes listed here:
https://clang.llvm.org/extra/clang-tidy/checks/list.html
The 'modernize-use-trailing-return-type' fix was excluded due to my
personal preference (more specifically, I think the 'auto' keyword is
misleading in that position).
This last change set was generated by a full clang-tidy run (including
compilation):
clang-tidy -p ~/projects/nix-build/ \
-checks=-*,readability-braces-around-statements -fix src/*/*.cc
Actually running clang-tidy requires some massaging to make it play
nice with Nix + meson, I'll be adding a wrapper or something for that soon.
