2020-08-03 r/1569 refactor(3p/nix): Build nix-daemon as a separate binaryVincent Ambo1-0/+131
Skips over all the monobinary stuff and moves to a separate binary for nix-daemon. 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.

2020-08-01 r/1519 feat(3p/nix): Implement AddToStore proto handlerGriffin Smith1-4/+4
Implement the proto handler for AddToStore, which adds a nix path to the store. This is implemented by adding a new (probably soon-to-be-generalized) Source concretion that wraps a grpc ServerReader for the stream of data we're receiving from the client - this is less than ideal, as it's perpetuating the source/sink thing that's going on and storing entire nars in memory, but is at the very worst an incremental step towards a functioning nix that we can refactor in the future.

2020-07-24 r/1457 fix(3p/nix): do not call vforkKane York1-1/+0
The use of vfork() in Nix is entirely illegal. Quote: If the process created by vfork() returns from the function in which vfork() was called, or calls any other function before successfully calling _exit() or one of the exec*() family of functions, the behavior is undefined. -- Linux man-pages, release 5.05 Add a TODO to use the higher-performance variants of clone() on Linux when it is available.

2020-07-20 r/1408 chore(3p/nix): Remove support for pluginsGriffin Smith1-2/+0
Plugins seem to not really be used anywhere (I can find one plugin that's actually defined, and it doesn't seem very useful, especially since we got rid of builtins.exec) and their presence is adding additional complexity and potential sources of bugs to an already unsteady refactor. At some point we may want to bring back something *like* plugins, but their design will likely be different and it will definitely be after we have a functioning Nix again.

2020-07-13 r/1278 refactor(3p/nix/libexpr): Make nix::AttrName a std::variantVincent Ambo1-1/+1
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.

2020-05-27 r/865 refactor(3p/nix): Anchor local includes at src/Vincent Ambo1-12/+12
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.
2020-05-25 r/846 refactor(3p/nix): Replace tokenizeStrings with absl::StrSplitVincent Ambo1-1/+1
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.
2020-05-24 r/840 style(3p/nix): Remove 'using std::*' from types.hhVincent Ambo1-16/+18
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 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).

2020-05-19 r/778 refactor(3p/nix): Make all single-argument constructors explicitVincent Ambo1-3/+3

2020-05-19 r/777 style(3p/nix): Final act in the brace-wrapping sagaVincent Ambo1-46/+74
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.
2020-05-19 r/772 style(3p/nix): Add braces around single-line for-loopsVincent Ambo1-4/+12

2020-05-19 r/767 style(3p/nix): Enforce braces around loops and conditionalsVincent Ambo1-10/+20
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.
