2011-11-29	* download-using-manifests: use the Perl bindings.	Eelco Dolstra

2011-10-10	* Set the executable bit on scripts.	Eelco Dolstra

2011-10-10	* Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under	Eelco Dolstra
	the Nix:: namespace.
2011-07-13	* Fix concurrency issues in download-using-manifests' handling of the	Eelco Dolstra
	SQLite manifest cache. The DBI AutoCommit feature caused every process to have an active transaction at all times, which could indefinitely block processes wanting to update the manifest cache. * Disable fsync() in the manifest cache because we don't need integrity (the cache can always be recreated if it gets corrupted).
2011-04-11	* configure: detect whether DBD::SQLite is present. If necessary the	Eelco Dolstra
	location to DBI and DBD::SQLite can be passed with --with-dbi and --with-dbd-sqlite.
2011-04-10	* Cache the manifests in /nix/var/nix/manifests in a SQLite database.	Eelco Dolstra
	This significantly speeds up the download-using-manifests substituter, especially if manifests are very large. For instance, one "nix-build -A geeqie" operation that updated four packages using binary patches went from 18.5s to 1.6s. It also significantly reduces memory use. The cache is kept in /nix/var/nix/manifests/cache.sqlite. It's updated automatically when manifests are added to or removed from /nix/var/nix/manifests. It might be interesting to have nix-pull store manifests directly in the DB, rather than storing them as separate flat files, but then we would need a command line interface to delete manifests from the DB.
2011-04-06	* Remove the localPaths feature in manifests since it's no longer used	Eelco Dolstra
	and redundant anyway.
2011-03-16	* Print a better error message.	Eelco Dolstra

2010-12-22	* In Hydra manifests the Size field is missing, so don't rely on it.	Eelco Dolstra
	This caused a lot of "Use of uninitialized value" warnings from Perl.
2010-12-13	* When doing a query (e.g. `nix-store -r --dry-run'), don't make a lot	Eelco Dolstra
	of expensive calls to `nix-store --check-validity'.
2010-12-05	* Use CamelCase for the Perl modules.	Eelco Dolstra

2010-11-17	* Oops.	Eelco Dolstra

2010-11-17	* When checking whether a patch is applicable, for efficiency, use	Eelco Dolstra
	`nix-store -q --hash' to get the hash of the base path rather than `nix-hash'. However, only do this for estimating the size of a download, not for the actual substitution, because sometimes the contents of store paths are modified (which they shouldn't, of course).
2010-11-17	* In the download size indication, take binary patches into account.	Eelco Dolstra
	Hopefully this doesn't slow things down too much.
2010-11-17	* Before a build, show the disk space that the downloaded store paths	Eelco Dolstra
	will approximately require.
2010-02-04	* "Fix" incorrect help message.	Eelco Dolstra

2010-02-02	* Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't	Eelco Dolstra
	support deleting the current directory.
2009-03-19	* Future proofing: assume we can read manifests up to version 10	Eelco Dolstra
	(which should therefore be backwards compatible).
2009-02-27	* nix-install-package: don't pollute /nix/var/nix/manifests.	Eelco Dolstra

2009-02-26	* Handle base-16 hashes in manifests.	Eelco Dolstra

2009-02-19	* download-using-manifests: don't check the cryptographic hash of	Eelco Dolstra
	downloaded files; rather, check the hash of the unpacked store path. When the server produces bzipped NAR archives on demand (like Hydra does), the hash of the file is not known in advance; it's streamed from the server. Thus the manifest doesn't contain a hash for the bzipped NAR archive. However, the server does know the hash of the uncompressed NAR archive (the "NarHash" field), since it's stored in the Nix database (nix-store -q --hash /nix/store/bla). So we use that instead for checking the integrity of the download.
2008-11-20	* Urgh.	Eelco Dolstra

2008-09-08	* Doh.	Eelco Dolstra

2008-08-04	* Doh.	Eelco Dolstra

2008-08-02	* Make nix-env --dry-run print the paths to be substituted correctly	Eelco Dolstra
	again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
2008-07-18	* Allow read-only access to the store (e.g., non-root users on NixOS	Eelco Dolstra
	can do operations like "nix-store -qR <path>" even without the Nix daemon).
2007-10-22	(no commit message)	Eelco Dolstra

2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra
	need any info on substitutable paths, we just call the substituters (such as download-using-manifests.pl) directly. This means that it's no longer necessary for nix-pull to register substitutes or for nix-channel to clear them, which makes those operations much faster (NIX-95). Also, we don't have to worry about keeping nix-pull manifests (in /nix/var/nix/manifests) and the database in sync with each other. The downside is that there is some overhead in calling an external program to get the substitutes info. For instance, "nix-env -qas" takes a bit longer. Abolishing the substitutes table also makes the logic in local-store.cc simpler, as we don't need to store info for invalid paths. On the downside, you cannot do things like "nix-store -qR" on a substitutable but invalid path (but nobody did that anyway). * Never catch interrupts (the Interrupted exception).
2007-01-23	* New kind of manifest object: "localPath", which denotes that a store	Eelco Dolstra
	path can be created by copying it from another location in the file system. This is useful in the NixOS installation.
2007-01-23	* Successors have been gone for ages.	Eelco Dolstra

2007-01-13	* Removed chroot support.	Eelco Dolstra

2006-10-04	* tmpnam() -> File::Temp::tempdir().	Eelco Dolstra

2006-09-25	* Clean up calls to system().	Eelco Dolstra

2006-08-05	prevent doing recursive chroots, by unsetting NIX_ROOT in the scripts.	Armijn Hemel

2006-08-04	* Remove the dependency on `date', use strftime instead.	Eelco Dolstra

2005-09-16	* Set the current directory to something well-defined. Might help in	Eelco Dolstra
	setuid installations.
2005-09-15	* Use a proper temporary directory.	Eelco Dolstra

2005-05-10	* Make unpacking of patch sequences much faster by not doing redundant	Eelco Dolstra
	unpacking and repacking of intermediate paths.
2005-04-12	* Argh! The patch downloader was broken due to the renaming of the	Eelco Dolstra
	`--isvalid' flag in nix-store.
2005-03-25	* Better error checking.	Eelco Dolstra

2005-03-14	* Pass `--base32' unless using MD5.	Eelco Dolstra

2005-03-14	* Parse new hash format properly.	Eelco Dolstra

2005-02-25	* Add a version number to manifests.	Eelco Dolstra

2005-02-24	* Properly specify the hash algorithm in the manifests, and read it	Eelco Dolstra
	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).
2005-01-25	* Really fix the substitute mechanism, i.e., ensure the closure	Eelco Dolstra
	invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-14	* Use absolute paths.	Eelco Dolstra

2005-01-12	* Print out less garbage.	Eelco Dolstra

2004-12-30	* More instrumentation (statistics go to /nix/var/log/nix/downloads).	Eelco Dolstra

2004-12-30	* Fix handling of chained patches: don't skip patches if intermediate	Eelco Dolstra
	paths are missing, etc.
2004-12-30	* Some logging for evaluation.	Eelco Dolstra
