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.

Configures the CMake build to load & run the GoogleTest tests.
I (grfn) also updated this to get the tests running as part of the nix
derivation, which required defining our own manual configurePhase and
installCheckPhase, rather than depending on the one provided by stdenv.
Not doing this would cause cmake to attempt to *run* the tests as part
of the buildPhase, which wouldn't work because the dynamic libraries
hadn't been put into a place where the test executables knew where to
find them. We're not sure *why* this fixes it, and for some reason
fixing this also breaks the automatic behavior of nixpkgs of passing
-j$NIX_BUILD_CORES -l$NIX_BUILD_CORES to make, but that's eaasy enough
to fix manually in a preBuild

These files were always implicitly depended upon by worker-protocol.hh, but just so happened also always be included in places where the other ones were already present.
We are likely getting rid of this file sooner rather than later, but in
the meantime this will cause clangd to shut up while I'm editing the
file.

malformed
Previously the nix-daemon would crash if a user fed it invalid store
paths for drv files. The crash was due to the changed assertion
triggering. Whenever that assertion would hit the nix-daemon process
along with all it's current childs (running builds from all users) would
be interrupted.
Before this patch:
$ nix-store --realise /nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
don't know how to build these paths:
/nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
error: unexpected end-of-file
< nix-daemon terminates >
With this patch:
$ nix-store --realise /nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
don't know how to build these paths:
/nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
error: path '/nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv' is not a valid store path
< nix-daemon does *NOT* terminate >

This isn't actually used yet, but forces the protos to be included in
the build which is useful for iteration.

This ensures that we install both glog's .a and all the .so files we
generate into a single consistent output lib path (which is, err,
lib64, but whatever).

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

The 'modernize-use-trailing-return-type' fix was excluded due to my

misleading in that position).

None of these are worthy of a specific commit, or even have a real
reason behind them, but I didn't want to lose them.

Implicit constructors can be confusing, especially in a codebase that
is already as unintentionally obfuscated as this one.

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 }'

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.

Removes the activity transfer that was previously nulled out from the
daemon protocol completely.
This might actually break Nix completely, I haven't tried yet, but
that's fine because this will be replaced with gRPC.
|
|
|
|
There are still remnants of the old build system (for example, the
build derivations are not yet updated at all), but we'll get there.
|

Reformatted with:
