2022-05-19 r/4098 chore(3p/nix): unvendor tvix 0.1Vincent Ambo1-85/+0
Nothing is using this now, and we'll likely never pick this up again, but we learned a lot in the process. Every now and then this breaks in some bizarre way on channel bumps and it's just a waste of time to maintain that.

2020-08-17 r/1657 refactor(tvix): add explicit copy/move constructors for ValueKane York1-0/+1
This is in preparation for making some of Value's members into refcounted ('smart') pointers. Change-Id: Ibc54e23ac35766a2fd4e14871c9a7c936a603778 Reviewed-on: https://cl.tvl.fyi/c/depot/+/1743 Tested-by: BuildkiteCI Reviewed-by: glittershark <grfn@gws.fyi>
2020-08-14 r/1646 refactor(tvix): completely remove boehm gcKane York1-2/+0
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.

2020-08-01 r/1525 chore(3p/nix/libexpr): Cleanups and notes in eval.ccKane York1-0/+1
Add two more garbage-collection flags. Annotate how terrible tExternal is. Prepare to fix the smuggle casting in ExprWith. Add a static_cast.

2020-07-16 r/1322 refactor(3p/nix/libexpr): Extract static helpers out of parser.yVincent Ambo1-0/+1
Moves several of the static helper functions into a new parser.cc file. Once the rest of the code is usefully extracted, these will be moved to a private namespace.

2020-07-16 r/1321 refactor(3p/nix/libexpr): Extract parser header out of Yacc fileVincent Ambo1-0/+1
First step (of many?) towards extracting all the inline code from the Yacc file and keeping it somewhere more accessible instead. Note that none of this code has previously been touched by a linter or formatter, pretty much ever, so as it is extracted it also undergoes similar changes to the whole codebase after the initial fork.

2020-05-28 r/868 refactor(3p/nix): Introduce CMake as the build system for NixVincent Ambo1-0/+75
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.
