Age	Commit message (Collapse)	Author	Files	Lines
2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra	1	-6/+26
	This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-01-27	Make hashLength32() a method of Hash	Eelco Dolstra	1	-9/+3

2015-11-04	Support SHA-512 hashes	Eelco Dolstra	1	-0/+7
	Fixes #679. Note: on x86_64, SHA-512 is considerably faster than SHA-256 (198 MB/s versus 131 MB/s).
2015-11-04	Require OpenSSL	Eelco Dolstra	1	-8/+0

2015-09-18	Shut up clang warnings	Eelco Dolstra	1	-1/+0

2015-02-03	Simplify parseHash32	Eelco Dolstra	1	-37/+10

2015-02-03	Simplify printHash32	Eelco Dolstra	1	-35/+17

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	1	-7/+7

2012-10-23	If hashes do not match, print them in base-32 for SHA-1/SHA-256	Eelco Dolstra	1	-0/+6
	Fixes #57.
2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra	1	-3/+3

2011-12-15	* Refactoring: move sink/source buffering into separate classes.	Eelco Dolstra	1	-10/+12
	* Buffer the HashSink. This speeds up hashing a bit because it prevents lots of calls to the hash update functions (e.g. nix-hash went from 9.3s to 8.7s of user time on the closure of my /var/run/current-system).
2011-12-02	* Move parseHash16or32 into libutil, and use in nix-hash.	Eelco Dolstra	1	-0/+16

2010-11-16	* Store the size of a store path in the database (to be precise, the	Eelco Dolstra	1	-3/+7
	size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra.
2010-03-09	* In `nix-store --export', abort if the contents of a path has	Eelco Dolstra	1	-0/+7
	changed. This prevents corrupt paths from spreading to other machines. Note that checking the hash is cheap because we're hashing anyway (because of the --sign feature).
2008-12-03	* Pass HashType values instead of strings.	Eelco Dolstra	1	-0/+9

2008-08-25	* Doh.	Eelco Dolstra	1	-1/+0

2008-08-25	* Strip off the `.nix' suffix from the attribute name for files in	Eelco Dolstra	1	-0/+1
	~/.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.
2008-05-21	* GCC 4.3.0 (Fedora 9) compatibility fixes. Reported by Gour and	Eelco Dolstra	1	-0/+1
	Armijn Hemel.
2007-02-21	* `nix-store --export --sign': sign the Nix archive using the RSA key	Eelco Dolstra	1	-15/+24
	in /nix/etc/nix/signing-key.sec
2006-12-12	* New primop builtins.filterSource, which can be used to filter files	Eelco Dolstra	1	-2/+2
	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.
2006-11-30	* Skeleton of the privileged worker program.	Eelco Dolstra	1	-1/+1
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
2006-09-20	* Print a better error message for wrong hashes (NIX-49).	Eelco Dolstra	1	-1/+7

2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-2/+9
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-03-09	* Ugh, printHash() was very inefficient because it used	Eelco Dolstra	1	-5/+7
	ostringstreams. Around 11% of execution time was spent here (now it's 0.5%).
2006-03-01	* Ouch, parseHash32 was completely broken. All digits >= 4 were	Eelco Dolstra	1	-1/+1
	parsed as 4. For a moment I worried that printHash32 was broken, and that would have been really, really bad ;-)
2006-02-13	* Optional switch "--with-openssl=<PATH>" to use OpenSSL's	Eelco Dolstra	1	-11/+15
	implementations of MD5, SHA-1 and SHA-256. The main benefit is that we get assembler-optimised implementations of MD5 and SHA-1 (though not SHA-256 (at least on x86), unfortunately). OpenSSL's SHA-1 implementation on Intel is twice as fast as ours.
2006-02-13	* Use a union.	Eelco Dolstra	1	-2/+1

2005-11-16	* Did something useful while waiting at IAD: reference scanning is now	Eelco Dolstra	1	-1/+5
	much faster.
2005-03-23	* Fix endianness bug.	Eelco Dolstra	1	-18/+18

2005-01-17	* Removed the `id' attribute hack.	Eelco Dolstra	1	-3/+61
	* Formalise the notion of fixed-output derivations, i.e., derivations for which a cryptographic hash of the output is known in advance. Changes to such derivations should not propagate upwards through the dependency graph. Previously this was done by specifying the hash component of the output path through the `id' attribute, but this is insecure since you can lie about it (i.e., you can specify any hash and then produce a completely different output). Now the responsibility for checking the output is moved from the builder to Nix itself. A fixed-output derivation can be created by specifying the `outputHash' and `outputHashAlgo' attributes, the latter taking values `md5', `sha1', and `sha256', and the former specifying the actual hash in hexadecimal or in base-32 (auto-detected by looking at the length of the attribute value). MD5 is included for compatibility but should be considered deprecated. * Removed the `drvPath' pseudo-attribute in derivation results. It's no longer necessary. * Cleaned up the support for multiple output paths in derivation store expressions. Each output now has a unique identifier (e.g., `out', `devel', `docs'). Previously there was no way to tell output paths apart at the store expression level. * `nix-hash' now has a flag `--base32' to specify that the hash should be printed in base-32 notation. * `fetchurl' accepts parameters `sha256' and `sha1' in addition to `md5'. * `nix-prefetch-url' now prints out a SHA-1 hash in base-32. (TODO: a flag to specify the hash.)
2005-01-14	* Shorten SHA-256 hashes used in store path name generation to 160	Eelco Dolstra	1	-6/+66
	bits, then encode them in a radix-32 representation (using digits and letters except e, o, u, and t). This produces store paths like /nix/store/4i0zb0z7f88mwghjirkz702a71dcfivn-aterm-2.3.1. The nice thing about this is that the hash part of the file name is still 32 characters, as before with MD5. (Of course, shortening SHA-256 to 160 bits makes it no better than SHA-160 in theory, but hopefully it's a bit more resistant to attacks; it's certainly a lot slower.)
2005-01-14	* Start move towards SHA-256 hashes instead of MD5.	Eelco Dolstra	1	-0/+1
	* Start cleaning up unique store path generation (they weren't always unique; in particular the suffix ("-aterm-2.2", "-builder.sh") was not part of the hash, therefore changes to the suffix would cause multiple store objects with the same hash).
2005-01-14	* Add SHA-256.	Eelco Dolstra	1	-0/+6
	* Tests for the various hashes.
2005-01-13	* Added SHA-1 support. `nix-hash' now has an option `--type sha1' to	Eelco Dolstra	1	-17/+70
	select SHA-1 hashing.
2005-01-13	* Refactoring to support SHA-1.	Eelco Dolstra	1	-8/+12

2003-11-18	* Source tree refactoring.	Eelco Dolstra	1	-0/+124
