2021-12-13Explicitly make GC roots client sockets blockingEelco Dolstra
On macOS / BSD, these sockets inherit the non-blocking flag of the server soocket, which is not what we want. https://github.com/dotnet/runtime/issues/25069 https://bugs.python.org/issue7995 https://hydra.nixos.org/build/161439304

The client thread can't just delete its own thread object from connections, it has to detach it.

2021-10-13Fix GC when there are cycles in the referrers graphEelco Dolstra
(where "referrers" includes the reverse of derivation outputs and derivers). Now we do a full traversal to look if we can reach any root. If not, all paths reached can be deleted.

2021-10-13Non-blocking garbage collectorEelco Dolstra
The garbage collector no longer blocks other processes from adding/building store paths or adding GC roots. To prevent the collector from deleting store paths just added by another process, processes need to connect to the garbage collector via a Unix domain socket to register new temporary roots.

2021-06-18UDSRemoteStore: Support the 'root' store parameterEelco Dolstra
Useful when we're using a daemon with a chroot store, e.g. $ NIX_DAEMON_SOCKET_PATH=/tmp/chroot/nix/var/nix/daemon-socket/socket nix-daemon --store /tmp/chroot Then the client can now connect with $ nix build --store unix:///tmp/chroot/nix/var/nix/daemon-socket/socket?root=/tmp/chroot nixpkgs#hello

2020-01-05build: fix sandboxing on darwinDaiderd Jordan
Starting ba87b08f8529e4d9f8c58d8c625152058ceadb75 getEnv now returns an std::optional which means these getEnv() != "" conditions no longer happen if the variables are not defined.
2019-12-10Make the Store API more type-safeEelco Dolstra
Most functions now take a StorePath argument rather than a Path (which is just an alias for std::string). The StorePath constructor ensures that the path is syntactically correct (i.e. it looks like <store-dir>/<base32-hash>-<name>). Similarly, functions like buildPaths() now take a StorePathWithOutputs, rather than abusing Path by adding a '!<outputs>' suffix. Note that the StorePath type is implemented in Rust. This involves some hackery to allow Rust values to be used directly in C++, via a helper type whose destructor calls the Rust type's drop() function. The main issue is the dynamic nature of C++ move semantics: after we have moved a Rust value, we should not call the drop function on the original value. So when we move a value, we set the original value to bitwise zero, and the destructor only calls drop() if the value is not bitwise zero. This should be sufficient for most types. Also lots of minor cleanups to the C++ API to make it more modern (e.g. using std::optional and std::string_view in some places).
2019-11-22getEnv(): Return std::optionalEelco Dolstra
This allows distinguishing between an empty value and no value.

mention `nix-store --query --roots` when a path cannot be deleted

It doesn't seem very reliable on ZFS.
