2013-06-20	Don't keep "disabled" substituters running	Eelco Dolstra	1	-0/+2
	For instance, it's pointless to keep copy-from-other-stores running if there are no other stores, or download-using-manifests if there are no manifests. This also speeds things up because we don't send queries to those substituters.
2012-10-17	nix-push: Only generate and copy a NAR if it doesn't already exist	Eelco Dolstra	1	-2/+2
	This prevents unnecessary and slow rebuilds of NARs that already exist in the binary cache.
2012-10-02	Add operation ‘nix-store --repair-path’	Eelco Dolstra	1	-3/+4
	This operation allows fixing corrupted or accidentally deleted store paths by redownloading them using substituters, if available. Since the corrupted path cannot be replaced atomically, there is a very small time window (one system call) during which neither the old (corrupted) nor the new (repaired) contents are available. So repairing should be used with some care on critical packages like Glibc.
2012-09-21	Style fix	Eelco Dolstra	1	-5/+5

2012-09-19	Support xz compression in the download-using-manifests substituter	Eelco Dolstra	1	-2/+8

2012-07-30	Do some validation of URLs	Eelco Dolstra	1	-0/+3

2012-07-27	Let build.cc verify the expected hash of a substituter's output	Eelco Dolstra	1	-11/+2
	Since SubstitutionGoal::finished() in build.cc computes the hash anyway, we can prevent the inefficiency of computing the hash twice by letting the substituter tell Nix about the expected hash, which can then verify it.
2012-07-27	download-using-manifests: Don't use nix-prefetch-url	Eelco Dolstra	1	-41/+29
	Instead call curl directly and pipe it into ‘nix-store --restore’. This saves I/O and prevents creating garbage in the Nix store.
2012-07-11	Update the other substituters	Eelco Dolstra	1	-40/+38

2011-11-29	* download-using-manifests: use the Perl bindings.	Eelco Dolstra	1	-37/+29

2011-10-10	* Set the executable bit on scripts.	Eelco Dolstra	1	-0/+0

2011-10-10	* Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under	Eelco Dolstra	1	-16/+14
	the Nix:: namespace.
2011-07-13	* Fix concurrency issues in download-using-manifests' handling of the	Eelco Dolstra	1	-0/+6
	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	1	-1/+1
	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	1	-26/+26
	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	1	-20/+2
	and redundant anyway.
2011-03-16	* Print a better error message.	Eelco Dolstra	1	-1/+1

2010-12-22	* In Hydra manifests the Size field is missing, so don't rely on it.	Eelco Dolstra	1	-2/+2
	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	1	-4/+12
	of expensive calls to `nix-store --check-validity'.
2010-12-05	* Use CamelCase for the Perl modules.	Eelco Dolstra	1	-1/+1

2010-11-17	* Oops.	Eelco Dolstra	1	-1/+1

2010-11-17	* When checking whether a patch is applicable, for efficiency, use	Eelco Dolstra	1	-3/+7
	`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	1	-144/+161
	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	1	-0/+2
	will approximately require.
2010-02-04	* "Fix" incorrect help message.	Eelco Dolstra	1	-1/+1

2010-02-02	* Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't	Eelco Dolstra	1	-2/+0
	support deleting the current directory.
2009-03-19	* Future proofing: assume we can read manifests up to version 10	Eelco Dolstra	1	-1/+6
	(which should therefore be backwards compatible).
2009-02-27	* nix-install-package: don't pollute /nix/var/nix/manifests.	Eelco Dolstra	1	-1/+1

2009-02-26	* Handle base-16 hashes in manifests.	Eelco Dolstra	1	-1/+12

2009-02-19	* download-using-manifests: don't check the cryptographic hash of	Eelco Dolstra	1	-18/+30
	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	1	-7/+9

2008-09-08	* Doh.	Eelco Dolstra	1	-1/+1

2008-08-04	* Doh.	Eelco Dolstra	1	-0/+2

2008-08-02	* Make nix-env --dry-run print the paths to be substituted correctly	Eelco Dolstra	1	-35/+42
	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	1	-1/+2
	can do operations like "nix-store -qR <path>" even without the Nix daemon).
2007-10-22	(no commit message)	Eelco Dolstra	1	-2/+0

2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-10/+48
	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	1	-1/+15
	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	1	-2/+1

2007-01-13	* Removed chroot support.	Eelco Dolstra	1	-2/+0

2006-10-04	* tmpnam() -> File::Temp::tempdir().	Eelco Dolstra	1	-4/+4

2006-09-25	* Clean up calls to system().	Eelco Dolstra	1	-11/+11

2006-08-05	prevent doing recursive chroots, by unsetting NIX_ROOT in the scripts.	Armijn Hemel	1	-0/+1

2006-08-04	* Remove the dependency on `date', use strftime instead.	Eelco Dolstra	1	-3/+2

2005-09-16	* Set the current directory to something well-defined. Might help in	Eelco Dolstra	1	-0/+2
	setuid installations.
2005-09-15	* Use a proper temporary directory.	Eelco Dolstra	1	-7/+19

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

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