2008-09-17 * Garbage collector: added an option `--use-atime' to delete paths inEelco Dolstra1-0/+30
order of ascending last access time. This is useful in conjunction with --max-freed or --max-links to prefer deleting non-recently used garbage, which is good (especially in the build farm) since garbage may become live again. The code could easily be modified to accept other criteria for ordering garbage by changing the comparison operator used by the priority queue in collectGarbage().
2008-08-02 * Make nix-env --dry-run print the paths to be substituted correctlyEelco Dolstra1-5/+14
again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
2008-06-18 * Garbage collector: option `--max-freed' to stop after at least NEelco Dolstra1-8/+2
bytes have been freed, `--max-links' to stop when the Nix store directory has fewer than N hard links (the latter being important for very large Nix stores on filesystems with a 32000 subdirectories limit).
2008-06-18 * Some refactoring: put the GC options / results in separate structs.Eelco Dolstra1-35/+78
* The garbage collector now also prints the number of blocks freed.
2008-06-09 * Merged the no-bdb branch (-r10900:HEADEelco Dolstra1-1/+10
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-01-29 * nix-store --dump-db / --load-db to dump/load the Nix DB.Eelco Dolstra1-1/+8
* nix-store --register-validity: option to supply the content hash of each path. * Removed compatibility with Nix <= 0.7 stores.
2007-11-29 * nix-env -e: support uninstalling by path, so that one can sayEelco Dolstra1-0/+10
$ nix-env -e $(which firefox) or $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132 * nix-env -i: if an argument contains a slash anywhere, treat it as a path and follow it through symlinks into the Nix store. This allows things like $ nix-build -A firefox $ nix-env -i ./result * nix-env -q/-i/-e: don't complain when the `*' selector doesn't match anything. In particular, `nix-env -q \*' doesn't fail anymore on an empty profile.
2007-08-12 * Get rid of the substitutes database table (NIX-47). Instead, if weEelco Dolstra1-33/+22
need any info on substitutable paths, we just call the substituters (such as download-using-manifests.pl) directly. This means that it's no longer necessary for nix-pull to register substitutes or for nix-channel to clear them, which makes those operations much faster (NIX-95). Also, we don't have to worry about keeping nix-pull manifests (in /nix/var/nix/manifests) and the database in sync with each other. The downside is that there is some overhead in calling an external program to get the substitutes info. For instance, "nix-env -qas" takes a bit longer. Abolishing the substitutes table also makes the logic in local-store.cc simpler, as we don't need to store info for invalid paths. On the downside, you cannot do things like "nix-store -qR" on a substitutable but invalid path (but nobody did that anyway). * Never catch interrupts (the Interrupted exception).
2007-06-12 * Support queryDeriver() in multi-user installations.Eelco Dolstra1-0/+4
2007-02-21 * `nix-store -qR' and friends: print the paths sorted topologicallyEelco Dolstra1-0/+5
under the references relation. This is useful for commands that want to copy paths to another Nix store in the right order.
2007-02-21 * `nix-store --import': import an archive created by `nix-storeEelco Dolstra1-0/+4
--export' into the Nix store, and optionally check the cryptographic signatures against /nix/etc/nix/signing-key.pub. (TODO: verify against a set of public keys.)
2007-02-20 * Start of `nix-store --export' operation for serialising a storeEelco Dolstra1-0/+8
path. This is like `nix-store --dump', only it also dumps the meta-information of the store path (references, deriver). Will add a `--sign' flag later to add a cryptographic signature, which we will use for exchanging store paths between build farm machines in a secure manner.
2007-01-29 * computeStorePathForText: take the references into account whenEelco Dolstra1-1/+2
computing the store path (NIX-77). This is an important security property in multi-user Nix stores. Note that this changes the store paths of derivations (since the derivation aterms are added using addTextToStore), but not most outputs (unless they use builtins.toFile).
2006-12-12 * New primop builtins.filterSource, which can be used to filter filesEelco Dolstra1-3/+7
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.
2006-12-05 * Allow unprivileged users to run the garbage collector and to doEelco Dolstra1-0/+48
`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 Dolstra1-0/+9
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/+7
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...
2006-12-02 * Move addTempRoot() to the store API, and add another functionEelco Dolstra1-0/+25
syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-12-01 * Merge addToStore and addToStoreFixed.Eelco Dolstra1-10/+7
* addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).
2006-12-01 * More operations.Eelco Dolstra1-3/+27
* 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 Dolstra1-2/+5
* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30 * Put building in the store API.Eelco Dolstra1-0/+13
2006-11-30 * Refactoring. There is now an abstract interface class StoreAPIEelco Dolstra1-0/+115
containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
