2014-11-19 nix-daemon: Call exit(), not _exit()Eelco Dolstra1-2/+2
This was preventing destructors from running. In particular, it was preventing the deletion of the temproot file for each worker process. It may also have been responsible for the excessive WAL growth on Hydra (due to the SQLite database not being closed properly). Apparently broken by accident in 8e9140cfdef9dbd1eb61e4c75c91d452ab5e4a74.

This makes allowed-users and trusted-users work on Mac OS X.

2014-07-23 nix-daemon: Use a thread instead of SIGPOLL to catch client disconnectsEelco Dolstra1-146/+7
The thread calls poll() to wait until a HUP (or other error event) happens on the client connection. If so, it sends SIGINT to the main thread, which is then cleaned up normally. This is much nicer than messing around with SIGPOLL.
2014-07-19 Revert old useBuildHook behaviourEelco Dolstra1-1/+1
2014-07-17 nix-daemon: Add trusted-users and allowed-users optionsEelco Dolstra1-3/+35
‘trusted-users’ is a list of users and groups that have elevated rights, such as the ability to specify binary caches. It defaults to ‘root’. A typical value would be ‘@wheel’ to specify all users in the wheel group. ‘allowed-users’ is a list of users and groups that are allowed to connect to the daemon. It defaults to ‘*’. A typical value would be ‘@users’ to specify the ‘users’ group.

C++11 lambdas ftw.
2014-06-10 Report daemon OOM betterEelco Dolstra1-4/+2
When copying a large path causes the daemon to run out of memory, you now get: error: Nix daemon out of memory instead of: error: writing to file: Broken pipe

2014-03-18 Allow recovery from isValidPath RPCs with an invalid pathLudovic Courtès1-1/+7
Currently, clients cannot recover from an isValidPath RPC with an invalid path parameter because the daemon closes the connection when that happens. More precisely: 1. in performOp, wopIsValidPath case, ‘readStorePath’ raises an ‘Error’ exception; 2. that exception is caught by the handler in ‘processConnection’; 3. the handler determines errorAllowed == false, and thus exits after sending the message. This last part is fixed by calling ‘startWork’ early on, as in the patch below. The same reasoning could be applied to all the RPCs that take one or more store paths as inputs, but isValidPath is, by definition, likely to be passed invalid paths in the first place, so it’s important for this one to allow recovery.

2013-08-07 Run the daemon worker on the same CPU as the clientEelco Dolstra1-0/+4
On a system with multiple CPUs, running Nix operations through the daemon is significantly slower than "direct" mode: $ NIX_REMOTE= nix-instantiate '<nixos>' -A system real 0m0.974s user 0m0.875s sys 0m0.088s $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m2.118s user 0m1.463s sys 0m0.218s The main reason seems to be that the client and the worker get moved to a different CPU after every call to the worker. This patch adds a hack to lock them to the same CPU. With this, the overhead of going through the daemon is very small: $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m1.074s user 0m0.809s sys 0m0.098s

2013-03-08 Revert "Prevent config.h from being clobbered"Eelco Dolstra1-1/+1
This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.

2012-12-20 nix-store -q --roots: Respect the gc-keep-outputs/gc-keep-derivations settingsEelco Dolstra1-0/+3
So if a path is not garbage solely because it's reachable from a root due to the gc-keep-outputs or gc-keep-derivations settings, ‘nix-store -q --roots’ now shows that root.
