2004-08-31 * Main the `substitutes-rev' table again, but now in a way thatEelco Dolstra1-1/+4
doesn't take \Theta(n^2) space/time complexity.
2004-08-25 * `--min-age' flag in nix-store and nix-collect-garbage to only deleteEelco Dolstra1-10/+15
unreachable paths that haven't been used for N hours. For instance, `nix-collect-garbage --min-age 168' only deletes paths that haven't been accessed in the last week. This is useful for instance in the build farm where many derivations can be shared between consecutive builds, and we wouldn't want a garbage collect to throw them all away. We could of course register them as roots, but then we'd to unregister them at some point, which would be a pain to manage. The `--min-age' flag gives us a sort of MRU caching scheme. BUG: this really shouldn't be in gc.cc since that violates mechanism/policy separation.
2004-08-25 * `nix-collect-garbage' now actually performs a garbage collection, itEelco Dolstra1-1/+1
doesn't just print the set of paths that should be deleted. So there is no more need to pipe the result into `nix-store --delete' (which doesn't even exist anymore).
2004-08-25 * Put the garbage collector in nix-store: operation `--gc',Eelco Dolstra1-13/+57
suboperations `--print-live', `--print-dead', and `--delete'. The roots are not determined by nix-store; they are read from standard input. This is to make it easy to customise what the roots are. The collector now no longer fails when store expressions are missing (which legally happens when using substitutes). It never tries to fetch paths through substitutes. TODO: acquire a global lock on the store while garbage collecting. * Removed `nix-store --delete'.
2004-06-28 * Added a switch `--fallback'. From the manual:Eelco Dolstra1-4/+2
Whenever Nix attempts to realise a derivation for which a closure is already known, but this closure cannot be realised, fall back on normalising the derivation. The most common scenario in which this is useful is when we have registered substitutes in order to perform binary distribution from, say, a network repository. If the repository is down, the realisation of the derivation will fail. When this option is specified, Nix will build the derivation instead. Thus, binary installation falls back on a source installation. This option is not the default since it is generally not desirable for a transient failure in obtaining the substitutes to lead to a full build from source (with the related consumption of resources).
2004-06-21 * Remove debug output.Eelco Dolstra1-1/+0
2004-06-21 * Wrap calls to registerSubstitute() in a single transaction toEelco Dolstra1-1/+7
improve throughput. * Don't build the `substitute-rev' table for now, since it caused Theta(N^2) time and log file consumption when adding N substitutes. Maybe we can do without it.
2004-06-20 * Re-enable support for substitutes in the normaliser.Eelco Dolstra1-23/+31
* A better substitute mechanism. Instead of generating a store expression for each store path for which we have a substitute, we can have a single store expression that builds a generic program that is invoked to build the desired store path, which is passed as an argument. This means that operations like `nix-pull' only produce O(1) files instead of O(N) files in the store when registering N substitutes. (It consumes O(N) database storage, of course, but that's not a performance problem). * Added a test for the substitute mechanism. * `nix-store --substitute' reads the substitutes from standard input, instead of from the command line. This prevents us from running into the kernel's limit on command line length.
2004-04-21 * Do initialise state (the DB etc.) when doing a `make install',Eelco Dolstra1-7/+0
unless `--disable-init-state' is passed to configure.
2004-02-16 * Allow linking against an external Berkeley DB / ATerm library.Eelco Dolstra1-2/+2
2004-02-16 * Allow the location of the store to be specified (--with-store-dir).Eelco Dolstra1-1/+1
* Do not create stuff in localstatedir when doing `make install' (since we may not have write access). In general, installation of constant code/data should be separate from the initialisation of mutable state.
2004-02-14 * The environment variable NIX_ROOT can now be set to execute Nix in aEelco Dolstra2-3/+34
chroot() environment. * A operation `--validpath' to register path validity. Useful for bootstrapping in a pure Nix environment. * Safety checks: ensure that files involved in store operations are in the store.
2004-02-06 * Improvements to profiles. Generations are now per-profile, e.g.,Eelco Dolstra1-3/+0
default -> default-94-link default-82-link -> /nix/store/cc4480... default-83-link -> /nix/store/caeec8... ... default-94-link -> /nix/store/2896ca... experimental -> experimental-2-link experimental-1-link -> /nix/store/cc4480... experimental-2-link -> /nix/store/a3148f... * `--profile' / `-p' -> `--switch-profile' / `-S' * `--link' / `-l' -> `--profile' / `-p' * The default profile is stored in $prefix/var/nix/profiles. $prefix/var/nix/links is gone. Profiles can be stored anywhere. * The current profile is now referenced from ~/.nix-profile, not ~/.nix-userenv. * The roots to the garbage collector now have extension `.gcroot', not `.id'.
2004-01-09 * Option `--force-realise' in `nix-store --query'.Eelco Dolstra1-5/+12

$ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
