2017-03-06Revert fa125b9b28bea25a4eeb4d39a71a481563127cb9Eelco Dolstra
This causes quadratic performance.
2017-03-01TeeSink: Pre-reserve string spaceEelco Dolstra
When receiving a very large file, this can prevent the string from having tobe copied, which temporarily doubles memory consumption.
2016-02-25Add NAR / Store accessor abstractionEelco Dolstra
This is primary to allow hydra-queue-runner to extract files like "nix-support/hydra-build-products" from NARs in binary caches.
2016-02-24BinaryCacheStore: Implement addToStore()Eelco Dolstra
So now you can do $ NIX_REMOTE=file:///tmp/binary-cache nix-instantiate '<nixpkgs>' -A hello and lots of other operations.
2014-07-16Handle case collisions on case-insensitive systemsEelco Dolstra
When running NixOps under Mac OS X, we need to be able to import store paths built on Linux into the local Nix store. However, HFS+ is usually case-insensitive, so if there are directories with file names that differ only in case, then importing will fail. The solution is to add a suffix ("~nix~case~hack~<integer>") to colliding files. For instance, if we have a directory containing xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to "xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR, the suffixes are removed. Thus, importing and exporting via a case-insensitive Nix store is round-tripping. So when NixOps calls nix-copy-closure to copy the path to a Linux machine, you get the original file names back. Closes #119.
2012-07-18Use "#pragma once" to prevent repeated header file inclusionEelco Dolstra
2010-05-04* Revert r15436. This was a workaround for a bug in btrfs which seemsEelco Dolstra
to have been fixed now.
2009-05-04Add an ftruncate call paired with fallocate to play safe with some FSes ↵Michael Raskin
(namely, BtrFS fallocate sets file size to allocated size, i.e. multiple of block size)
2009-03-22* NAR archives: handle files larger than 2^32 bytes. Previously itEelco Dolstra
would just silently store only (fileSize % 2^32) bytes. * Use posix_fallocate if available when unpacking archives. * Provide a better error message when trying to unpack something that isn't a NAR archive.
2008-12-03* A simple API for parsing NAR archives.Eelco Dolstra
2006-12-12* New primop builtins.filterSource, which can be used to filter filesEelco Dolstra
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.
2006-12-12* In dumpPath(): pass a function object that allows files to beEelco Dolstra
selectively in/excluded from the dump.
2006-11-30* Skeleton of the privileged worker program.Eelco Dolstra
* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
2006-09-04* Use a proper namespace.Eelco Dolstra
* Optimise header file usage a bit. * Compile the parser as C++.
2005-03-03* Don't use fork() in copyPath(), but a string buffer.Eelco Dolstra
2003-11-18* Source tree refactoring.Eelco Dolstra
