2007-09-02 explanation what happens when passing true / false and null values to ↵Marc Weber1-0/+4
derivation builders added
2007-08-30 * Create the Nix daemon socket in a separate directoryEelco Dolstra2-4/+10
(/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.
2007-08-28 * When there are multiple substituters, make sure to release theEelco Dolstra1-0/+5
lock on the output path after trying each. Otherwise the pathIsLockedByMe() test gets confused.
2007-08-28 * Fix a race condition with parallel builds where multipleEelco Dolstra3-10/+96
fixed-output derivations or substitutions try to build the same store path at the same time. Locking generally catches this, but not between multiple goals in the same process. This happened especially often (actually, only) in the build farm with fetchurl downloads of the same file being executed on multiple machines and then copied back to the main machine where they would clobber each other (NIXBF-13). Solution: if a goal notices that the output path is already locked, then go to sleep until another goal finishes (hopefully the one locking the path) and try again.
2007-08-28 * Doh! Broken test.Eelco Dolstra1-3/+3
2007-08-28 * PathLocks::lockPaths: don't allow reacquiring a lock we alreadyEelco Dolstra2-5/+5
hold.
2007-08-28 * Test case to show that parallel builds of different fixed-outputEelco Dolstra3-1/+28
derivations that produce the same output path don't work properly wrt locking. This happens a lot in the build farm when fetchurl derivations downloading the same file on different platforms are executed in parallel and then copied back to the main machine.
2007-08-22 * nix-channel: supports users who don't have write permission to theEelco Dolstra1-12/+21
manifests directory. In that case, we don't do a nix-pull, so the user gets pure source deployment. The directory /nix/var/nix/gcroots/per-user/$USER should be writable. (It's created automatically if /nix/var/nix/gcroots/per-user is writable, e.g. if it has 1777 permission.)
2007-08-18 primop functions listToAttrs (+test), __isAttrs, __trace addedMarc Weber3-0/+62
new configuration style proposal in lib/default-unstable.nix
2007-08-15 * Show errors in nix-prefetch-url.Eelco Dolstra3-4/+5
2007-08-14 * Hopefully this fixes the test on FreeBSD.Eelco Dolstra2-3/+3
2007-08-14 * Fix the tests.Eelco Dolstra1-1/+2
2007-08-13 * A test for the nix-worker.Eelco Dolstra4-2/+24
2007-08-13 * Fix the tests.Eelco Dolstra12-63/+67
2007-08-13 * Bump the Nix database schema version number; delete the substitutesEelco Dolstra2-5/+33
table.
2007-08-13 * Backwards compatibility.Eelco Dolstra1-2/+2
2007-08-12 * Get rid of the substitutes database table (NIX-47). Instead, if weEelco Dolstra24-469/+357
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).
2007-08-10 * nix-pull: support bzipped manifests: when doing a nix-pull on $url,Eelco Dolstra1-8/+32
try $url.bz2 first.
2007-08-10 * Enable nix-prefetch-url caching in nix-channel.Eelco Dolstra2-3/+9
2007-08-10 * Don't rely on /dev/stdin.Eelco Dolstra1-1/+2
2007-08-09 * nix-pull: using nix-prefetch-url (so that we get caching for free),Eelco Dolstra2-10/+11
and store the manifests in the Nix store. (So now /nix/var/nix/manifests/ just contains symlinks to the store and is searched for GC roots.)
2007-08-09 * nix-prefetch-url: support caching. If the environment variableEelco Dolstra3-13/+58
NIX_DOWNLOAD_CACHE is set, then nix-prefetch-url will store the hash and timestamp of downloaded files in the directory $NIX_DOWNLOAD_CACHE. This allows it to figure out if the file is still in the Nix store.
2007-08-07 * Use the new patched version of the aterm library.Eelco Dolstra1-3/+3
2007-08-07 * Don't allocate input files on the stack.Eelco Dolstra1-14/+2
2007-08-06 * Optionally warn about packages that give an assertion failure.Eelco Dolstra1-1/+1
2007-07-05 * Properly keep packages during upgrades.Eelco Dolstra1-1/+4
2007-06-12 * Support queryDeriver() in multi-user installations.Eelco Dolstra10-16/+42
2007-06-11 * Distribute bzip2 1.0.4.Eelco Dolstra1-3/+3
2007-06-11 * Check against creation of GC roots in the store. Those roots don'tEelco Dolstra2-3/+7
work, because findRoots() stops when it encounters a symlink to the store. And of course the store is supposed to be read-only.
2007-06-04 * Remove debug statement.Eelco Dolstra1-1/+0
2007-06-02 change default NIX_HASH_ALGOArmijn Hemel1-1/+1
2007-05-16 (no commit message)Eelco Dolstra3-44/+80
2007-05-16 * New builtin function "isFunction". You're not supposed to use itEelco Dolstra3-2/+15
;-) * Channels: fix channels that are plain lists of derivations (like strategoxt-unstable) instead of functions (like nixpkgs-unstable). This fixes the error message "error: the left-hand side of the function call is neither a function nor a primop (built-in operation) but a list".
2007-05-15 * Allow empty argument lists in function definitions (e.g., `{}:Eelco Dolstra3-0/+3
bla'). Also allow trailing commas (`{x, y,}: ...') as a unintented consequence. Hopefully the reduce/reduce conflict won't cause any problems.
2007-05-14 * Typo (reported by Marc Weber).Eelco Dolstra1-1/+1
2007-05-07 * Create the database directory if it doesn't exist.Eelco Dolstra1-0/+9
2007-05-02 * Set the right priorities when recovering from a directoryEelco Dolstra1-1/+1
collision.
2007-05-02 (no commit message)Eelco Dolstra1-1/+0
2007-05-01 * Give unpacked channels more sensible names than 0, 1, ... They nowEelco Dolstra5-20/+43
get the basename of the channel URL (e.g., nixpkgs-unstable). The top-level Nix expression of the channel is now an attribute set, the attributes of which are the individual channels (e.g., {nixpkgs_unstable = ...; strategoxt_unstable = ...}). This makes attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible, e.g., "nix-env -iA nixpkgs_unstable.subversion".
2007-05-01 * nix-env -i: instead of breaking package ties by version, break themEelco Dolstra4-13/+54
by priority and version install. That is, if there are multiple packages with the same name, then pick the package with the highest priority, and only use the version if there are multiple packages with the same priority. This makes it possible to mark specific versions/variant in Nixpkgs more or less desirable than others. A typical example would be a beta version of some package (e.g., "gcc-4.2.0rc1") which should not be installed even though it is the highest version, except when it is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1"). * Idem for nix-env -u, only the semantics are a bit trickier since we also need to take into account the priority of the currently installed package (we never upgrade to a lower priority, unless --always is given).
2007-05-01 * Set a terminate() handler to ensure that we leave the BDBEelco Dolstra6-8/+55
environment cleanly even when an exception is thrown from a destructor. We still crash, but we don't take all other Nix processes with us.
2007-05-01 * Make --verify more interruptable.Eelco Dolstra1-0/+1
2007-05-01 * `nix-env -q --xml --meta' to show all meta attributes.Eelco Dolstra3-3/+19
2007-04-30 * Doh.Eelco Dolstra1-1/+1
2007-04-27 * Package flag "keep" that prevents a package from being removed fromEelco Dolstra2-3/+8
a user environment by an install or upgrade action. This is particularly useful if you have a version installed that you don't want to upgrade (e.g., because the newer versions are broken). Example: $ nix-env -u zapping --dry-run (dry run; not doing anything) upgrading `zapping-0.9.6' to `zapping-0.10cvs6' $ nix-env --set-flag keep true zapping $ nix-env -u zapping --dry-run (dry run; not doing anything) However, "-e" will still uninstall the package. (Maybe we should require the keep flag to be explicitly set to false before it can be uninstalled.)
2007-04-27 * Package conflict resolution through priority levels. If there is aEelco Dolstra3-20/+48
user environment collission between two packages due to overlapping file names, then a package with a higher priority will overwrite the symlinks of a package with a lower priority. E.g., $ nix-env --set-flag priority 5 gcc $ nix-env --set-flag priority 10 binutils gives gcc a higher priority than binutils (higher number = lower priority).
2007-04-27 * Allow conflicting packages to be kept in a user environment, andEelco Dolstra2-3/+11
allow switching between them (NIX-80). Example: two versions of Pan: $ nix-env -q pan pan-0.128 pan-0.14.2.91 $ readlink $(which pan) /nix/store/l38jrbilw269drpjkx7kinhrxj6fjh59-pan-0.14.2.91/bin/pan At most one of them can be active any given time. Assuming than 0.14.2.91 is active, you can active 0.128 as follows: $ nix-env --set-flag active false pan-0.14.2.91 $ nix-env --set-flag active true pan-0.128 $ readlink $(which pan) /nix/store/nziqwnlzy7xl385kglxhg75pfl5i936n-pan-0.128/bin/pan More flags to follow.
2007-04-26 * nix-env -q now has a flag --prebuilt-only (-b<) that causes nix-envEelco Dolstra3-6/+25
to show only those derivations whose output is already in the Nix store or that can be substituted (i.e., downloaded from somewhere). In other words, it shows the packages that can be installed “quickly”, i.e., don’t need to be built from source.
2007-04-16 * Updated dependency information.Eelco Dolstra1-9/+10
