2009-11-20 * Remove the --use-atime / --max-atime garbage collector flags. ManyEelco Dolstra1-2/+3
(Linux) machines no longer maintain the atime because it's too expensive, and on the machines where --use-atime is useful (like the buildfarm), reading the atimes on the entire Nix store takes way too much time to make it practical.
2009-11-06 * Remove support for old (before Nix 0.12pre12020) databases.Eelco Dolstra1-2/+2
2009-10-08 Added optional parameter which adds -lnsl -lsocket to make the Nix package ↵Sander van der Burg1-1/+1
manager work on OpenSolaris
2009-09-30 * Support platforms that don't have O_ASYNC (e.g. OpenSolarisEelco Dolstra1-3/+17
apparently).
2009-03-23 * Shut up a GCC warning.Eelco Dolstra1-2/+2
2008-12-16 * Pass --use-atime / --max-atime to the daemon.Eelco Dolstra1-0/+4
2008-12-12 * We can't use string objects in signal handlers because they mightEelco Dolstra1-4/+4
allocate memory, which is verboten in signal handlers. This caused random failures in the test suite on Mac OS X (triggered by the spurious SIGPOLL signals on Mac OS X, which should also be fixed).
2008-12-03 * addToStore() in nix-worker: don't write the NAR dump received fromEelco Dolstra1-6/+52
the client to a temporary directory, as that is highly inefficient.
2008-12-03 * Backwards compatibility.Eelco Dolstra1-4/+9
2008-12-03 * Pass HashType values instead of strings.Eelco Dolstra1-1/+1
2008-12-03 * Unify the treatment of sources copied to the store, and recursiveEelco Dolstra1-2/+2
SHA-256 outputs of fixed-output derivations. I.e. they now produce the same store path: $ nix-store --add x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x $ nix-store --add-fixed --recursive sha256 x /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x the latter being the same as the path that a derivation derivation { name = "x"; outputHashAlgo = "sha256"; outputHashMode = "recursive"; outputHash = "..."; ... }; produces. This does change the output path for such fixed-output derivations. Fortunately they are quite rare. The most common use is fetchsvn calls with SHA-256 hashes. (There are a handful of those is Nixpkgs, mostly unstable development packages.) * Documented the computation of store paths (in store-api.cc).
2008-11-20 * Nix daemon: reload the configuration file after forking (NIX-100).Eelco Dolstra1-1/+5
2008-11-14 * Prevent zombies. Previous the SIGCHLD handler only reaped oneEelco Dolstra1-1/+1
zombie at a time, so if multiple children died before the handler got to run, some of them would not be cleaned up.
2008-11-12 * Some somewhat ad hoc mechanism to allow the build farm to monitorEelco Dolstra1-1/+4
build progress.
2008-11-11 * Pass the --no-build-output flag to the daemon.Eelco Dolstra1-0/+2
2008-08-04 * querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra1-2/+16
* --dry-run: print the paths that we don't know how to build/substitute.
2008-06-18 * Some refactoring: put the GC options / results in separate structs.Eelco Dolstra1-12/+13
* The garbage collector now also prints the number of blocks freed.
2008-06-14 * nix-worker: clean up the temporary root for the worker processes Eelco Dolstra1-0/+2
in /nix/var/nix/temproots.
2008-06-09 * Merged the no-bdb branch (-r10900:HEADEelco Dolstra1-1/+1
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-04-09 * sockaddr_un doesn't allow path names of more than 108 characters.Eelco Dolstra1-3/+11
This isn't usually a problem, except that it causes tests to fail when performed in a directory with a very long path name. So chdir to the socket directory and use a relative path name.
2008-03-20 * Disable the don't-run-as-root sanity check because it breaks RPMEelco Dolstra1-0/+2
builds (which are done as root...).
2007-11-16 * Flag `--no-build-hook' to disable distributed builds.Eelco Dolstra1-2/+5
* queryDeriver in daemon mode: don't barf if the other side returns an empty string (which means there is no deriver).
2007-09-18 * Pass various options to the worker so that flags like -K or -j workEelco Dolstra1-1/+19
in multi-user Nix (NIX-72). * Client/worker: exchange a protocol version number for future compatibility.
2007-08-30 * Create the Nix daemon socket in a separate directoryEelco Dolstra1-1/+4
(/nix/var/nix/daemon-socket). This allows access to the Nix daemon to be restricted by setting the mode/ownership on that directory as desired, e.g. $ chmod 770 /nix/var/nix/daemon-socket $ chown root.wheel /nix/var/nix/daemon-socket to allow only users in the wheel group to use Nix. Setting the ownership on a socket is much trickier, since the socket must be deleted and recreated every time the daemon is started (which would require additional Nix configuration file directives to specify the mode/ownership, and wouldn't support arbitrary ACLs), some BSD variants appear to ignore permissions on sockets, and it's not clear whether the umask is respected on every platform when creating sockets.
2007-06-12 * Support queryDeriver() in multi-user installations.Eelco Dolstra1-0/+9
2007-03-28 * Handle ECONNRESET from the client. Also, don't abort() if there areEelco Dolstra1-4/+9
unexpected conditions in the SIGPOLL handler, since that messes up the Berkeley DB environment (which a client must never be able to trigger).
2007-02-22 * Handle EINTR in select().Eelco Dolstra1-3/+3
2007-02-21 * `nix-store --import' now also works in remote mode. The workerEelco Dolstra1-1/+35
always requires a signature on the archive. This is to ensure that unprivileged users cannot add Trojan horses to the Nix store.
2007-02-21 * Support exportPath() in remote mode.Eelco Dolstra1-0/+26
2006-12-12 * New primop builtins.filterSource, which can be used to filter filesEelco Dolstra1-2/+1
from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way.
2006-12-07 * Doh!Eelco Dolstra1-1/+1
2006-12-07 * Rename all those main.cc files.Eelco Dolstra2-1/+1
2006-12-06 * Fix the safety check.Eelco Dolstra1-2/+2
2006-12-05 * Tricky: child processes should not send data to the client sinceEelco Dolstra1-2/+10
that might mess up the protocol. And besides, the socket file descriptor is probably closed.
2006-12-05 * Oops! In daemon mode, we can't run as root either if build-users is empty.Eelco Dolstra1-2/+2
2006-12-05 * Use an explicit handler for SIGCHLD, since SIG_IGN doesn't do the Eelco Dolstra1-3/+15
right thing on FreeBSD 4 (it leaves zombies).
2006-12-05 * Ugly hack to handle spurious SIGPOLLs.Eelco Dolstra1-20/+50
2006-12-05 * Some renaming.Eelco Dolstra1-6/+6
2006-12-05 * Allow unprivileged users to run the garbage collector and to doEelco Dolstra1-0/+22
`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 privilegedEelco Dolstra1-17/+12
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.
2006-12-04 * Add indirect root registration to the protocol so that unprivilegedEelco Dolstra1-0/+10
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 Dolstra1-0/+5
2006-12-04 * Handle exceptions and stderr for all protocol functions.Eelco Dolstra1-19/+54
* 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 serverEelco Dolstra1-33/+150
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 * Install the worker in bindir, not libexecdir.Eelco Dolstra1-1/+1
* Allow the worker path to be overriden through the NIX_WORKER environment variable.
2006-12-03 * Don't run setuid root when build-users is empty.Eelco Dolstra1-25/+49
* Send startup errors to the client.
2006-12-03 * Handle a subtle race condition: the client closing the socketEelco Dolstra1-2/+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 Dolstra1-1/+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 * Some hackery to propagate the worker's stderr and exceptions to theEelco Dolstra1-95/+150
client.
2006-12-03 * Run the worker in a separate session to prevent terminal signalsEelco Dolstra1-0/+6
from interfering.
