2008-09-17 * GC option `--max-atime' that specifies an upper limit to the lastEelco Dolstra4-7/+24
accessed time of paths that may be deleted. Anything more recently used won't be deleted. The time is specified in time_t, e.g. seconds since 1970-01-01 00:00:00 UTC; use `date +%s' to convert to time_t from the command line. Example: to delete everything that hasn't been used in the last two months: $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")
2008-09-17 * Typo.Eelco Dolstra1-1/+1
2008-09-17 * Some refactoring. Better output with `-v' for --use-atime.Eelco Dolstra2-35/+40
2008-09-17 * nix-store --gc / --delete: show how many store paths were deleted.Eelco Dolstra1-1/+2
2008-09-17 * Garbage collector: added an option `--use-atime' to delete paths inEelco Dolstra6-56/+222
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().
2008-09-02 * When writing the user environment manifest, filter out non-stringEelco Dolstra1-7/+9
attributes from the meta attribute. Not doing so caused nix-env to barf on the "psi" package, which has a meta.function attribute, the textual serialisation of which causes a gigantic string to be produced --- so big that it causes nix-env to run out of memory. Note however that "meta" really only should contain strings. meta.function should be passthru.function.
2008-08-27 * Explicitly set PWD to prevent problems with chroot builds. InEelco Dolstra1-0/+6
particular, dietlibc cannot figure out the cwd because the inode of the current directory doesn't appear in .. (because getdents returns the inode of the mount point).
2008-08-27 * Create a /tmp with 1777 permission in the chroot. Some buildersEelco Dolstra1-12/+32
need a writable /tmp (they don't respect $TMPDIR).
2008-08-26 * Require that __overrides is defined as a non-recursive attributeEelco Dolstra1-1/+1
(which means it can only be defined via "inherit"), otherwise we get scoping bugs, since __overrides can't be recursive (or at least, it would be hard).
2008-08-25 * Disable chroot builds for fixed-output derivations so that we don'tEelco Dolstra1-1/+8
need /etc in the chroot (in particular, /etc/resolv.conf for fetchurl). Not having /etc/resolv.conf in the chroot is a good thing, since we don't want normal derivations to download files.
2008-08-25 * Evaluate attributes in sorted order for better determinism.Eelco Dolstra1-7/+16
2008-08-25 * Minor simplification.Eelco Dolstra2-10/+7
2008-08-25 * Doh.Eelco Dolstra1-1/+0
2008-08-25 * Strip off the `.nix' suffix from the attribute name for files inEelco Dolstra5-6/+27
~/.nix-defexpr, otherwise the attribute cannot be selected with the `-A' option. Useful if you want to stick a Nix expression directly in ~/.nix-defexpr.
2008-08-14 Fixing an obvious typo in override code. I do not know whether it works ↵Michael Raskin1-1/+1
correctly after the change, but at least it ca nbe compiled now.
2008-08-14 * Another experimental feature: a way to truly override attributes inEelco Dolstra2-2/+25
a rec. This will be very useful to allow end-user customisation of all-packages.nix, for instance globally overriding GCC or some other dependency. The // operator doesn't cut it: you could replace the "gcc" attribute, but all other attributes would continue to reference the original value due to the substitution semantics of rec. The syntax is a bit hacky but this is to allow backwards compatibility.
2008-08-14 * Added an experimental feature suggested by Andres: ellipses ("...")Eelco Dolstra7-18/+37
in attribute set pattern matches. This allows defining a function that takes *at least* the listed attributes, while ignoring additional attributes. For instance, {stdenv, fetchurl, fuse, ...}: stdenv.mkDerivation { ... }; defines a function that requires an attribute set that contains the specified attributes but ignores others. The main advantage is that we can then write in all-packages.nix aefs = import ../bla/aefs pkgs; instead of aefs = import ../bla/aefs { inherit stdenv fetchurl fuse; }; This saves a lot of typing (not to mention not having to update all-packages.nix with purely mechanical changes). It saves as much typing as the "args: with args;" style, but has the advantage that the function arguments are properly declared (not implicit in what the body of the "with" uses).
2008-08-14 * Backward compatibility check to prevent nixos-rebuild from barfingEelco Dolstra2-1/+2
when upgrading Nix.
2008-08-14 * @-patterns as in Haskell. For instance, in a function definitionEelco Dolstra5-46/+74
f = args @ {x, y, z}: ...; `args' refers to the argument as a whole, which is further pattern-matched against the attribute set pattern {x, y, z}.
2008-08-14 * "pattern" non-terminal.Eelco Dolstra1-5/+8
2008-08-14 * Refactoring: combine functions that take an attribute set andEelco Dolstra7-135/+165
functions that take a single argument (plain lambdas) into one AST node (Function) that contains a Pattern node describing the arguments. Current patterns are single lazy arguments (VarPat) and matching against an attribute set (AttrsPat). This refactoring allows other kinds of patterns to be added easily, such as Haskell-style @-patterns, or list pattern matching.
2008-08-14 * Increase the sleep periods a bit to make the test less likely toEelco Dolstra1-4/+0
fail on slow machines. Of course it would be better if this test wasn't timing dependent...
2008-08-11 * Removed the "valid values" feature. Nobody uses it anyway.Eelco Dolstra5-70/+18
2008-08-05 * Better error checking of the data from the substituters.Eelco Dolstra1-21/+16
2008-08-04 * Use optimistic profile locking for nix-env operations like `-i' andEelco Dolstra1-138/+163
`-u'. Instead of acquiring an exclusive lock on the profile for the entire duration of the operation, we just perform the operation optimistically (without an exclusive lock), and check at the end whether the profile changed while we were busy (i.e., the symlink target changed). If so, the operation is restarted. Restarting is generally cheap, since the build results are still in the Nix store. Most of the time, only the user environment has to be rebuilt.
2008-08-04 * `nix-env --set': support --dry-run.Eelco Dolstra1-3/+10
2008-08-04 * `nix-store --realise': print what paths will be built/downloaded,Eelco Dolstra4-37/+50
just like nix-env. * `nix-store --realise': --dry-run option.
2008-08-04 * build.cc: only use a substituter if it returns info for a path.Eelco Dolstra3-51/+57
2008-08-04 * Always show what paths we're going to build/download (as inEelco Dolstra1-9/+7
--dry-run). Maybe there should be an option to turn this on/off?
2008-08-04 * nix-env --dry-run: show the total size of the substituterEelco Dolstra4-5/+15
downloads.
2008-08-04 * querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra7-16/+49
* --dry-run: print the paths that we don't know how to build/substitute.
2008-08-02 * Make nix-env --dry-run print the paths to be substituted correctlyEelco Dolstra10-180/+211
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.
2008-07-24 * Print a better error message when a non-derivation attribute set isEelco Dolstra1-3/+10
coerced to a string.
2008-07-18 * Allow read-only access to the store (e.g., non-root users on NixOSEelco Dolstra1-5/+9
can do operations like "nix-store -qR <path>" even without the Nix daemon).
2008-07-18 * Use the copy-from-other-stores substituter by default. Of course,Eelco Dolstra1-3/+4
it only does something if $NIX_OTHER_STORES (not really a good name...) is set. * Do globbing on the elements of $NIX_OTHER_STORES. E.g. you could set it to /mnts/*/nix or something. * Install substituters in libexec/nix/substituters.
2008-07-11 * Generalised the dependencyClosure primop to builtins.genericClosure,Eelco Dolstra1-137/+55
which is hopefully more useful. * New primops: length, mul, div.
2008-07-01 * Export the nix-env derivation name parsing and version comparisonEelco Dolstra5-37/+54
logic through the `parseDrvName' and `compareVersions' primops. This will allow expressions to easily check whether some dependency is a specific needed version or falls in some version range. See tests/lang/eval-okay-versions.nix for examples.
2008-06-18 (no commit message)Eelco Dolstra1-1/+1
2008-06-18 * --max-freed: support values >= 4 GB.Eelco Dolstra4-3/+12
2008-06-18 * Garbage collector: option `--max-freed' to stop after at least NEelco Dolstra6-12/+47
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 * `nix-store --optimise': handle files with >= 32000 hard links.Eelco Dolstra1-6/+31
(There can easily be more than 32000 occurrences of the empty file.)
2008-06-18 * Some refactoring: put the GC options / results in separate structs.Eelco Dolstra15-166/+252
* 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 Dolstra3-9/+13
in /nix/var/nix/temproots.
2008-06-14 * Note.Eelco Dolstra1-1/+5
2008-06-13 * Garbage collector: don't do a complete topological sort of the NixEelco Dolstra2-74/+87
store under the reference relation, since that means that the garbage collector will need a long time to start deleting paths. Instead just delete the referrers of a path first.
2008-06-13 * Print some progress info during the early GC stages.Eelco Dolstra2-1/+9
2008-06-09 * Merged the no-bdb branch (-r10900:HEADEelco Dolstra17-691/+786
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-04 First attempt to update Nix SDF grammar to match the actual bison grammarSander van der Burg1-2/+4
2008-05-21 * GCC 4.3.0 (Fedora 9) compatibility fixes. Reported by Gour andEelco Dolstra11-3/+18
Armijn Hemel.
2008-04-09 * sockaddr_un doesn't allow path names of more than 108 characters.Eelco Dolstra2-6/+26
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.
