At some point the behavior of this function got changed as part of our
cleanup - this fixes it to behave the way the rest of the codebase
expects (and how it is documented in the header) and covers it with a
few tests.

Add a rapidcheck test covering roundtrip parse and serialize for Nix
derivations. This covers a bug we discovered in ef54f5d which broke this
roundtrip.

The use of `unwrap_throw` can be used as a later grep target.

Implement the main function for the new, proto-based nix daemon. This
mostly replicates the behavior of the previous nix daemon - it starts a
grpc server listening on the same nix socket path and supports the same
set of options - with the exception of --stdio, which has been renamed
to --pipe and documented in the man page.

Implement the proto handler on the server side for
Worker::BuildDerivation. This includes several additions to the proto
which I had missed on the first pass, including the actual proto
definition for the Derivation itself and a few sequence number
reorderings which are fine because this is all provisional and not
deployed yet.
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.

Slight performance optimisation of nix::printString by copying chunks
of the input string which do not need escaping as contiguous blocks.

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.
|
|
Uses the equivalent absl::StartsWith and absl::EndsWith functions
instead.
|
|
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.

This applies the performance fixes listed here:
https://clang.llvm.org/extra/clang-tidy/checks/list.html
|

This applies the readability fixes listed here:

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.

This statement got included in a loop when it shouldn't have been. At
least it led to some funny derivation files!
|
|
These were not caught by the previous clang-tidy invocation, but were
instead sorted out using amber[0] as such:
ambr --regex 'for (\(.+\))\s([a-z].*;)' 'for $1 { $2 }'
[0]: https://github.com/dalance/amber

This change was generated with:
fd -e cc -e hh | xargs -I{} clang-tidy {} -p ~/projects/nix-build/ \
--checks='-*,readability-braces-around-statements' --fix \
-fix-errors
Some manual fixes were applied because some convoluted unbraced
statements couldn't be untangled by clang-tidy.
This commit still includes invalid files, but I decided to clean them
up in a subsequent commit so that it becomes more obvious where
clang-tidy failed. Maybe this will allow for a bug-report to
clang-tidy.
