| 2006-12-05 | * Tricky: child processes should not send data to the client since | Eelco Dolstra | 1 | -2/+10 | |
| that might mess up the protocol. And besides, the socket file descriptor is probably closed. | |||||
| 2006-12-05 | * FreeBSD returns ESRCH when there are no processes to kill. | Eelco Dolstra | 1 | -4/+8 | |
| 2006-12-05 | * Oops! In daemon mode, we can't run as root either if build-users is empty. | Eelco Dolstra | 1 | -2/+2 | |
| 2006-12-05 | * Use an explicit handler for SIGCHLD, since SIG_IGN doesn't do the | Eelco Dolstra | 1 | -3/+15 | |
| right thing on FreeBSD 4 (it leaves zombies). | |||||
| 2006-12-05 | * Better message. | Eelco Dolstra | 1 | -1/+1 | |
| 2006-12-05 | * Ugly hack to handle spurious SIGPOLLs. | Eelco Dolstra | 1 | -20/+50 | |
| 2006-12-05 | * Some renaming. | Eelco Dolstra | 1 | -6/+6 | |
| 2006-12-05 | * Redundant. | Eelco Dolstra | 4 | -130/+0 | |
| 2006-12-05 | * Allow unprivileged users to run the garbage collector and to do | Eelco Dolstra | 16 | -56/+106 | |
| `nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well. | |||||
| 2006-12-05 | * The determination of the root set should be made by the privileged | Eelco Dolstra | 9 | -77/+138 | |
| process, so forward the operation. * Spam the user about GC misconfigurations (NIX-71). * findRoots: skip all roots that are unreadable - the warnings with which we spam the user should be enough. | |||||
| 2006-12-05 | * findRoots: return a map from the symlink (outside of the store) to | Eelco Dolstra | 1 | -11/+16 | |
| the store path (inside the store). | |||||
| 2006-12-05 | * In addPermRoot, check that the root that we just registered can be | Eelco Dolstra | 2 | -18/+42 | |
| found by the garbage collector. This addresses NIX-71 and is a particular concern in multi-user stores. | |||||
| 2006-12-04 | * Add indirect root registration to the protocol so that unprivileged | Eelco Dolstra | 7 | -6/+42 | |
| processes can register indirect roots. Of course, there is still the problem that the garbage collector can only read the targets of the indirect roots when it's running as root... | |||||
| 2006-12-04 | * Not every OS knows about SIGPOLL. | Eelco Dolstra | 1 | -0/+5 | |
| 2006-12-04 | * Don't redirect stderr. | Eelco Dolstra | 1 | -6/+0 | |
| 2006-12-04 | * Handle exceptions and stderr for all protocol functions. | Eelco Dolstra | 2 | -19/+64 | |
| * SIGIO -> SIGPOLL (POSIX calls it that). * Use sigaction instead of signal to register the SIGPOLL handler. Sigaction is better defined, and a handler registered with signal appears not to interrupt fcntl(..., F_SETLKW, ...), which is bad. | |||||
| 2006-12-04 | * Daemon mode (`nix-worker --daemon'). Clients connect to the server | Eelco Dolstra | 7 | -53/+182 | |
| via the Unix domain socket in /nix/var/nix/daemon.socket. The server forks a worker process per connection. * readString(): use the heap, not the stack. * Some protocol fixes. | |||||
| 2006-12-04 | * When NIX_REMOTE=daemon, connect to /nix/var/nix/daemon.socket | Eelco Dolstra | 3 | -8/+37 | |
| instead of forking a worker. | |||||
| 2006-12-04 | * Refactoring. | Eelco Dolstra | 3 | -17/+33 | |
| 2006-12-04 | * Pass the verbosity level to the worker. | Eelco Dolstra | 1 | -2/+8 | |
| 2006-12-04 | * Install the worker in bindir, not libexecdir. | Eelco Dolstra | 6 | -2/+11 | |
| * Allow the worker path to be overriden through the NIX_WORKER environment variable. | |||||
| 2006-12-03 | * Doh. | Eelco Dolstra | 2 | -1/+4 | |
| 2006-12-03 | * Don't run setuid root when build-users is empty. | Eelco Dolstra | 3 | -26/+51 | |
| * Send startup errors to the client. | |||||
| 2006-12-03 | * Removed `build-allow-root'. | Eelco Dolstra | 5 | -39/+61 | |
| * Added `build-users-group', the group under which builds are to be performed. * Check that /nix/store has 1775 permission and is owner by the build-users-group. | |||||
| 2006-12-03 | * Use setreuid if setresuid is not available. | Eelco Dolstra | 2 | -7/+17 | |
| 2006-12-03 | * Handle a subtle race condition: the client closing the socket | Eelco Dolstra | 1 | -2/+30 | |
| between the last worker read/write and the enabling of the signal handler. | |||||
| 2006-12-03 | * Some hardcore magic to handle asynchronous client disconnects. | Eelco Dolstra | 1 | -1/+37 | |
| The problem is that when we kill the client while the worker is building, and the builder is not writing anything to stderr, then the worker never notice that the socket is closed on the other side, so it just continues indefinitely. The solution is to catch SIGIO, which is sent when the far side of the socket closes, and simulate an normal interruption. Of course, SIGIO is also sent every time the client sends data over the socket, so we only enable the signal handler when we're not expecting any data... | |||||
| 2006-12-03 | * Use a Unix domain socket instead of pipes. | Eelco Dolstra | 2 | -15/+18 | |
| 2006-12-03 | * Better error message if the worker doesn't start. | Eelco Dolstra | 1 | -4/+8 | |
| 2006-12-03 | * Pid::kill() should be interruptable. | Eelco Dolstra | 1 | -1/+3 | |
| 2006-12-03 | * Some hackery to propagate the worker's stderr and exceptions to the | Eelco Dolstra | 7 | -104/+206 | |
| client. | |||||
| 2006-12-03 | * Run the worker in a separate session to prevent terminal signals | Eelco Dolstra | 1 | -0/+6 | |
| from interfering. | |||||
| 2006-12-02 | * Move addTempRoot() to the store API, and add another function | Eelco Dolstra | 11 | -17/+81 | |
| syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock. | |||||
| 2006-12-02 | * Doh. | Eelco Dolstra | 1 | -1/+1 | |
| 2006-12-02 | * Remove most of the old setuid code. | Eelco Dolstra | 3 | -138/+57 | |
| * Much simpler setuid code for the worker in slave mode. | |||||
| 2006-12-02 | * Remove SwitchToOriginalUser, we're not going to need it anymore. | Eelco Dolstra | 8 | -63/+4 | |
| 2006-12-02 | * Clear NIX_REMOTE in the tests. | Eelco Dolstra | 1 | -0/+2 | |
| 2006-12-02 | * Remove queryPathHash(). | Eelco Dolstra | 4 | -2/+32 | |
| * Help for nix-worker. | |||||
| 2006-12-01 | * Replace read-only calls to addTextToStore. | Eelco Dolstra | 2 | -3/+9 | |
| 2006-12-01 | * Merge addToStore and addToStoreFixed. | Eelco Dolstra | 11 | -96/+40 | |
| * addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath). | |||||
| 2006-12-01 | * Right name. | Eelco Dolstra | 1 | -2/+2 | |
| 2006-12-01 | * More operations. | Eelco Dolstra | 5 | -33/+116 | |
| * addToStore() and friends: don't do a round-trip to the worker if we're only interested in the path (i.e., in read-only mode). | |||||
| 2006-11-30 | * More remote operations. | Eelco Dolstra | 12 | -46/+138 | |
| * Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0. | |||||
| 2006-11-30 | * Doh. | Eelco Dolstra | 1 | -1/+1 | |
| 2006-11-30 | * More operations. | Eelco Dolstra | 3 | -9/+50 | |
| 2006-11-30 | * First remote operation: isValidPath(). | Eelco Dolstra | 4 | -7/+63 | |
| 2006-11-30 | * When NIX_REMOTE is set to "slave", fork off nix-worker in slave | Eelco Dolstra | 5 | -24/+87 | |
| mode. Presumably nix-worker would be setuid to the Nix store user. The worker performs all operations on the Nix store and database, so the caller can be completely unprivileged. This is already much more secure than the old setuid scheme, since the worker doesn't need to do Nix expression evaluation and so on. Most importantly, this means that it doesn't need to access any user files, with all resulting security risks; it only performs pure store operations. Once this works, it is easy to move to a daemon model that forks off a worker for connections established through a Unix domain socket. That would be even more secure. | |||||
| 2006-11-30 | * Skeleton of the privileged worker program. | Eelco Dolstra | 12 | -126/+255 | |
| * Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation. | |||||
| 2006-11-30 | * Oops. | Eelco Dolstra | 2 | -0/+135 | |
| 2006-11-30 | * Skeleton of remote store implementation. | Eelco Dolstra | 4 | -6/+14 | |
