Eelco Dolstra	5116214343	Add support for uncompressed NARs in binary caches ... Issue NixOS/hydra#102.	2013-07-01 21:03:14 +02:00
Eelco Dolstra	6b1e671ac6	Fix xz compression	2012-07-01 21:57:25 -04:00
Eelco Dolstra	f4190c38ba	Allow both bzip2 and xz compression	2012-07-01 18:46:38 -04:00
Eelco Dolstra	4911a10a4e	Use XZ compression in binary caches ... XZ compresses significantly better than bzip2. Here are the compression ratios and execution times (using 4 cores in parallel) on my /var/run/current-system (3.1 GiB): bzip2: total compressed size 849.56 MiB, 30.8% [2m08] xz -6: total compressed size 641.84 MiB, 23.4% [6m53] xz -7: total compressed size 621.82 MiB, 22.6% [7m19] xz -8: total compressed size 599.33 MiB, 21.8% [7m18] xz -9: total compressed size 588.18 MiB, 21.4% [7m40] Note that compression takes much longer. More importantly, however, decompression is much faster: bzip2: 1m47.274s xz -6: 0m55.446s xz -7: 0m54.119s xz -8: 0m52.388s xz -9: 0m51.842s The only downside to using -9 is that decompression takes a fair amount (~65 MB) of memory.	2012-06-29 15:24:52 -04:00
Eelco Dolstra	663c06e8cd	Disable building in chroot for Nix's corepkgs ... The dependencies of the corepkgs are not necessarily in the chroot (or in the Nix store), so don't build them in a chroot.	2012-05-09 22:14:36 -04:00
Eelco Dolstra	ef902274fd	Remove unnecessary "system" argument	2012-04-14 18:48:11 +02:00
Eelco Dolstra	48cea0d01e	* Refactoring: Get rid of a few subdirectories in corepkgs/, and some ... other simplifications. * Use <nix/...> to locate the corepkgs. This allows them to be overriden through $NIX_PATH. * Use bash's pipefail option in the NAR builder so that we don't need to create a temporary file.	2012-01-03 00:16:29 +00:00
