2006-09-20 * Use paths, not strings, when calling the function that generatesEelco Dolstra1-10/+17
NARs. Fixes the impurity of nix-push (NIX-21). * Better help.
2006-09-19 * Doh.Eelco Dolstra1-2/+1
2006-09-19 * Doh! Of course we have to take execute permission into account.Eelco Dolstra1-2/+9
* Restore the mtime on modified directories.
2006-09-19 * `optimise-store.pl' reduces disk space consumption by hard-linkingEelco Dolstra1-16/+40
all identitical files in the Nix store to each other. (Previously it only computed the size that would be saved by doing so.)
2006-09-19 * Cleanups.Eelco Dolstra1-19/+12
2006-09-19 * `show-duplication.pl', a small utility that shows the amount ofEelco Dolstra2-1/+73
package duplication present in (e.g.) a profile. It shows the number of instances of each package in a closure, along with the size in bytes of each instance as well as the "waste" (the difference between the sum of the sizes of all instances and the average size). $ ./show-duplication.pl /nix/var/nix/profiles/default gcc 11 3.3.6 19293318 3.4.4 21425257 ... average 14942970, waste 149429707 coreutils 6 ... average package duplication 1.87628865979381, total size 3486330471, total waste 1335324237, 38.3017114443825% wasted This utility is useful for measuring the cost in terms of disk space of the Nix approach.
2006-09-06 * Convenience option `nix-collect-garbage -d' (--delete-old): removesEelco Dolstra1-2/+42
old generations of *all* profiles in /nix/var/nix/profiles, then runs the garbage collector. Quick way to get rid of all old stuff. Of course, one cannot roll back to earlier points in time after this.
2006-08-09 * file:/ -> file://Eelco Dolstra1-1/+1
2006-08-08 rework the --target flag. If this flag is used, a URI should be given. DefaultArmijn Hemel1-4/+4
values are not changed.
2006-08-07 * In nar.nix, path -> storePath, otherwise we get a collision betweenEelco Dolstra1-1/+1
environment variable names on Cygwin (where they are case insensitive).
2006-08-05 add coreutils to the default PATH for this scripts, so we know for sure we ↵Armijn Hemel1-0/+3
have tools like rm, mkdir, and so on
2006-08-05 prevent doing recursive chroots, by unsetting NIX_ROOT in the scripts.Armijn Hemel2-0/+4
2006-08-04 * Use old-school pipe opens; the new style is Perl >= 5.8.0.Eelco Dolstra1-2/+3
2006-08-04 * Remove the dependency on `date', use strftime instead.Eelco Dolstra1-3/+2
2006-08-03 urgh...for some weird reason this one-liner was not in svn. PEBKAC!Armijn Hemel1-1/+1
2006-08-01 * Better error checking.Eelco Dolstra1-2/+2
2006-08-01 add a flag --target, so we can override the URL in the MANIFEST file. ThisArmijn Hemel1-0/+9
is only for local copies (so file:///)
2006-07-28 * `nix-instantiate ... --arg NAME VALUE': allow arguments to be passedEelco Dolstra1-2/+10
to functions from the command line. * nix-build: started removing backticks.
2006-07-21 * Don't try to do DNS lookups.Eelco Dolstra2-2/+2
2006-07-19 * Added a tool to find additional roots for the garbage collector,Eelco Dolstra2-2/+62
such as open files, current directories, mmaped files, etc. This is inherently unportable, but it's easy to adapt this script to other platforms. Currently we call `lsof' and try to read various bits in /proc/NNN. The goal is to prevent the garbage collector from removing store paths that are no longer reachable from a permanent root but that are still in use (for instance, after the user has done "nix-env -e" on a running program).
2006-05-31 * This may be useful in the future.Eelco Dolstra3-2/+21
2006-05-08 * Remove old manifests in `nix-channel --update'.Eelco Dolstra1-0/+8
2006-03-14 * Allow the resulting symlink of nix-build to be named, e.g.,Eelco Dolstra1-9/+31
$ nix-build .../i686-linux.nix -A apacheHttpd -o apache
2006-03-10 * Write messages to stderr, not stdout.Eelco Dolstra1-1/+1
2006-03-03 * More online help.Eelco Dolstra1-1/+15
2006-03-03 * Rewrote nix-build in Perl, since sh is just too limited (turns outEelco Dolstra1-78/+87
that arrays are a bash extension, so it didn't work on FreeBSD). Also fixes NIX-8 (readlink(1) dependency).
2006-02-24 * Remove debug statement.Eelco Dolstra1-3/+0
2006-02-24 * A script to remove from a manifest those patches whose base orEelco Dolstra1-0/+77
target no longer applies to any available release. This is a partial fix for NIX-34 (when producing linear patch sequences between releases, the number of patches grows without bound).
2006-02-24 * Canonicalise manifests a bit by sorting them.Eelco Dolstra1-2/+2
2006-02-22 * Separate the cache reading code.Eelco Dolstra2-25/+28
2006-02-22 * Directory for nix.cs.uu.nl manifest / cache maintenance scripts.Eelco Dolstra2-0/+2
2006-02-22 * Use right directories for NAR files and patches.Eelco Dolstra1-4/+5
* Print errors to STDERR.
2006-02-10 * Enable the --attr in nix-build as well (and add -A as an alias).Eelco Dolstra1-6/+15
Example: $ nix-build ./all-packages.nix -A xlibs.libX11 So finally it's easy to perform a test build of a Nix expression!
2006-02-01 * Add @bindir@.Eelco Dolstra1-1/+1
2006-01-26 * Don't force a build of derivations.Eelco Dolstra1-2/+1
2006-01-12 * New tools nix-pack-closure and nix-unpack-closure. These provide aEelco Dolstra3-2/+152
useful way to transfer the closure of a store path to another machine. These commands provide functionality previously possible through `nix-push --copy'. However, they are much more convenient in many situations (though possibly less efficient). Example: $ nix-pack-closure /nix/store/hj232g1r...-subversion-1.3.0 > svn.closure (on another machine:) $ nix-unpack-closure < svn.closure Note that Subversion is added to the store, but not installed into a user environment. One should do `nix-env -i /nix/store/hj232g1r...-subversion-1.3.0' for that. Another example: copy the application Azureus to the machine `scratchy' through ssh: $ nix-pack-closure $(which azureus) | ssh scratchy nix-unpack-closure
2005-12-13 * Change `referer' to `referrer' throughout. In particular, theEelco Dolstra1-7/+7
nix-store query options `--referer' and `--referer-closure' have been changed to `--referrer' and `--referrer-closure' (but the old ones are still accepted for compatibility).
2005-11-17 * FreeBSD compatibility fix.Eelco Dolstra1-1/+2
2005-10-29 * Turn off build hooks in nix-push because of an impurity (NIX-21).Eelco Dolstra1-1/+11
2005-10-11 add @coreutils@ to correctly use coreutils to create a profile. This is neededArmijn Hemel1-1/+1
for NixOS, where we might not know our PATH in advance.
2005-09-21 * Remove other uses of IPC::Open2.Eelco Dolstra1-20/+8
2005-09-21 * Don't use IPC::Open2, it has a subtle race bug on Mac OS X 10.4. IfEelco Dolstra1-8/+2
the parent runs before the child, it closes some pipe file descriptors which causes the child to fail due to a bad file descriptor. So we just use the normal open() function instead. This fixes NIX-14 (intermittent nix-pull failures).
2005-09-16 * Remove dead file.Eelco Dolstra1-2/+0
2005-09-16 * Set the current directory to something well-defined. Might help inEelco Dolstra1-0/+2
setuid installations.
2005-09-15 * Use a proper temporary directory.Eelco Dolstra1-7/+19
2005-07-13 * nix-build: default to `./default.nix' if no paths are specified.Eelco Dolstra1-28/+38
So when using Nix as a build tool, you can just say `nix-build' and it will build the top-level derivation defined in `default.nix'.
2005-06-18 * Don't create patches for archives >= 150 MB because bsdiff can'tEelco Dolstra1-1/+13
handle it. It crashed on the 234 MB tetex archive. Probably we will never be able to handle archives of that size on 32-bit machines (because bsdiff does everything in memory requiring max(17*n,9*n+m)+O(1) bytes, so the address space simply isn't there).
2005-05-10 * Make unpacking of patch sequences much faster by not doing redundantEelco Dolstra1-16/+32
unpacking and repacking of intermediate paths.
2005-04-12 * Argh! The patch downloader was broken due to the renaming of theEelco Dolstra1-1/+1
`--isvalid' flag in nix-store.
2005-04-12 * Damn. Disable the USE heuristic for now, since the deriver in theEelco Dolstra1-4/+4
database isn't always in the manifest (so the reference graph cannot be reconstructed fully).
