2005-07-13	* nix-build: default to `./default.nix' if no paths are specified.	Eelco Dolstra	1	-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't	Eelco Dolstra	1	-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(17n,9n+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 redundant	Eelco Dolstra	1	-16/+32
	unpacking and repacking of intermediate paths.
2005-04-12	* Argh! The patch downloader was broken due to the renaming of the	Eelco Dolstra	1	-1/+1
	`--isvalid' flag in nix-store.
2005-04-12	* Damn. Disable the USE heuristic for now, since the deriver in the	Eelco Dolstra	1	-4/+4
	database isn't always in the manifest (so the reference graph cannot be reconstructed fully).
2005-04-08	* nix-store: `--substitute' -> `--register-substitutes'.	Eelco Dolstra	1	-1/+1

2005-04-07	* Get rid of fetchurl, we don't need it anymore.	Eelco Dolstra	1	-8/+8

2005-04-07	* `nix-store --add-fixed' to preload the outputs of fixed-output	Eelco Dolstra	1	-32/+31
	derivations. This is mostly to simplify the implementation of nix-prefetch-{url, svn}, which now work properly in setuid installations. * Enforce valid store names in `nix-store --add / --add-fixed'.
2005-04-04	* I said it couldn't be done. I was wrong.	Eelco Dolstra	1	-0/+111

2005-03-25	* Better error checking.	Eelco Dolstra	1	-0/+1

2005-03-18	* Ignore hash conflicts in gc-releases.pl.	Eelco Dolstra	3	-5/+10

2005-03-15	* Use SHA-256 for nix-push.	Eelco Dolstra	2	-18/+30

2005-03-14	* Idem.	Eelco Dolstra	1	-1/+1

2005-03-14	* Pass `--base32' unless using MD5.	Eelco Dolstra	1	-1/+3

2005-03-14	* Parse new hash format properly.	Eelco Dolstra	1	-6/+15

2005-03-14	* Print SHA-1 hashes in base-32 by default.	Eelco Dolstra	1	-2/+7

2005-03-14	* Prefix hash algorithm in patch generator too.	Eelco Dolstra	1	-8/+9

2005-03-14	* Set NAR name to content hash; previous nix-push names were not	Eelco Dolstra	2	-25/+13
	unique. * Drop `hashAlgo' attribute in manifests; prefix hashes with the hash algorithm instead.
2005-03-14	* Script to garbage collect nix-push directories. It prints out all	Eelco Dolstra	1	-0/+75
	file names in the directory not included in any of the manifests specified on the command line.
2005-03-11	* nix-install-package: install outPath, not drvPath, for now.	Eelco Dolstra	2	-2/+3
	* nix-prefecth-url: print out in base-16.
2005-03-03	* Channel fix.	Eelco Dolstra	1	-1/+1

2005-03-01	* Doh!	Eelco Dolstra	1	-1/+1

2005-03-01	* Add missing file to dist.	Eelco Dolstra	1	-1/+2

2005-03-01	* Use a weighted use heuristic to disambiguate between multiple	Eelco Dolstra	1	-8/+77
	occurances of a component. If the shortest path distance between a component P and Q in the referers graph is D, then the contribution of Q to the use of P is 1 / R^D, where R >= 1, typically 2. This expresses that distant indirect uses are less important than nearby uses. For instance, this can disambiguate between the bootstrap GCC in Nixpkgs and the GCC of the final stdenv (the former has more uses, but they are further away), and between the GCC of the final stdenv and the GCC+G77 build (the latter has very few uses).
2005-02-28	* Added a disambiguation heuristic: if two components have the same	Eelco Dolstra	2	-4/+24
	name but differ to much in sice (by more than a factor of 3), then never generate a patch.
2005-02-25	* Add a version number to manifests.	Eelco Dolstra	3	-2/+16

2005-02-25	* Pause if errors occur.	Eelco Dolstra	1	-1/+1

2005-02-25	* nix-install-package: Use the new (trivial) package format generated	Eelco Dolstra	1	-21/+34
	by the build farm. See e.g., http://catamaran.labs.cs.uu.nl/dist/nixpkgs-0.8/nixpkgs-0.7pre2302/; the user can click on packages, and they will be installed (assuming the `application/nix-package' MIME type has been associated with `nix-install-package'). Nix expressions are no longer involved: a "package" is just a pointer to a manifest, and the top-level store derivation to be added to the user environment. This makes these packages independent from Nix expression evolution. Note that we install the store derivation ($drvPath), not the resulting output path ($outPath). This is equivalent, except that installing the derivation maintains the back-link from the output path to the derivation that built it. This is useful for maintenance. * Automatically re-exec in an xterm so that the user sees something when `nix-install-package' is run from a browser.
2005-02-24	* Properly specify the hash algorithm in the manifests, and read it	Eelco Dolstra	4	-13/+31
	too. * Change the default hash for nix-prefetch-url back to md5, since that's what we use in Nixpkgs (for now; a birthday attack is rather unlikely there).
2005-02-24	* (Unnecessary) refactoring.	Eelco Dolstra	1	-29/+36

2005-02-22	* Support for fixed-output hashes over directory trees (i.e., over the	Eelco Dolstra	1	-2/+2
	NAR dump of the path).
2005-02-17	* Fix nix-channel.	Eelco Dolstra	2	-25/+63
	* Add `--help' flag; fixes NIX-5. * Add `--remove' flag; fixes NIX-6. * Add `--list' flag.
2005-02-09	* Propagate the deriver of a path through the substitute mechanism.	Eelco Dolstra	3	-25/+17
	* Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests.
2005-02-08	* Set umask to prevent permission problems.	Eelco Dolstra	1	-0/+4

2005-02-08	* Better error reporting in readmanifest.	Eelco Dolstra	2	-2/+3
	* Use force flag in `mv' to prevent silly interactive questions (this happens with shared Nix stores).
2005-02-01	* Remove debug code.	Eelco Dolstra	1	-2/+2

2005-02-01	* Make check fixes.	Eelco Dolstra	1	-3/+3

2005-02-01	* Move root finding from `nix-collect-garbage' to `nix-store --gc'.	Eelco Dolstra	1	-83/+2
	This was necessary becase root finding must be done after acquisition of the global GC lock. This makes `nix-collect-garbage' obsolete; it is now just a wrapper around `nix-store --gc'. * Automatically remove stale GC roots (i.e., indirect GC roots that point to non-existent paths).
2005-02-01	* nix-build: use an indirection scheme to make it easier for users to	Eelco Dolstra	1	-17/+28
	get rid of GC roots. Nix-build places a symlink `result' in the current directory. Previously, removing that symlink would not remove the store path being linked to as a GC root. Now, the GC root created by nix-build is actually a symlink in `/nix/var/nix/gcroots/auto' to `result'. So if that symlink is removed the GC root automatically becomes invalid (since it can no longer be resolved). The root itself is not automatically removed - the garbage collector should delete dangling roots.
2005-02-01	* nix-store, nix-instantiate: added an option `--add-root' to	Eelco Dolstra	1	-2/+9
	immediately add the result as a permanent GC root. This is the only way to prevent a race with the garbage collector. For instance, the old style ln -s $(nix-store -r $(nix-instantiate foo.nix)) \ /nix/var/nix/gcroots/result has two time windows in which the garbage collector can interfere (by GC'ing the derivation and the output, respectively). On the other hand, nix-store --add-root /nix/var/nix/gcroots/result -r \ $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \ foo.nix) is safe. * nix-build: use `--add-root' to prevent GC races.
2005-02-01	* Get rid of hardcoded paths.	Eelco Dolstra	1	-7/+7

2005-01-31	* Start of concurrent garbage collection. Processes write temporary	Eelco Dolstra	1	-1/+5
	roots to a per-process temporary file in /nix/var/nix/temproots while holding a write lock on that file. The garbage collector acquires read locks on all those files, thus blocking further progress in other Nix processes, and reads the sets of temporary roots.
2005-01-27	* Fix and simplify the garbage collector (it's still not concurrent,	Eelco Dolstra	2	-33/+22
	though). In particular it's now much easier to register a GC root. Just place a symlink to whatever store path it is that you want to keep in /nix/var/nix/gcroots.
2005-01-25	* Really fix the substitute mechanism, i.e., ensure the closure	Eelco Dolstra	5	-54/+118
	invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-19	* Set the Perl search path properly (reported by Roy van den Broek).	Eelco Dolstra	1	-1/+1

2005-01-17	* Removed the `id' attribute hack.	Eelco Dolstra	1	-2/+6
	* 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	* Use absolute paths.	Eelco Dolstra	2	-8/+8

2005-01-12	* Script to remove patches from manifests.	Eelco Dolstra	1	-0/+19

2005-01-12	* Print out less garbage.	Eelco Dolstra	1	-8/+10

2005-01-05	* Prototype store optimiser. It searched the Nix store for identical	Eelco Dolstra	1	-0/+69
	files and hard-links them to each other to save disk space. Currently it doesn't actually do the hard-linking, it just reports the amount of space saved if it did.
