2023-02-07	NarInfoDiskCache: Keep BinaryCache.id stable and improve test	Robert Hensing
	Fixes #3898 The entire `BinaryCaches` row used to get replaced after it became stale according to the `timestamp` column. In a concurrent scenario, this leads to foreign key conflicts as different instances of the in-process `state.caches` cache now differ, with the consequence that the older process still tries to use the `id` number of the old record. Furthermore, this phenomenon appears to have caused the cache for actual narinfos to be erased about every week, while the default ttl for narinfos was supposed to be 30 days.

2023-02-07	NarInfoDiskCache: Rename cacheExists -> upToDateCacheExists	Robert Hensing
	This is slightly more accurate considering that an outdated record may exist in the persistent cache. Possibly-outdated records are quite relevant as they may be foreign keys to more recent information that we want to keep, but we will not return them here.
2021-05-06	Add a realisations disk cache	regnat
	Similar to the nar-info disk cache (and using the same db). This makes rebuilds muuch faster. - This works regardless of the ca-derivations experimental feature. I could modify the logic to not touch the db if the flag isn’t there, but given that this is a trash-able local cache, it doesn’t seem to be really worth it. - We could unify the `NARs` and `Realisation` tables to only have one generic kv table. This is left as an exercise to the reader. - I didn’t update the cache db version number as the new schema just adds a new table to the previous one, so the db will be transparently migrated and is backwards-compatible. Fix #4746
2020-03-24	Misc changes from the flakes branch	Eelco Dolstra

2019-12-17	Add priority setting to stores	Eelco Dolstra
	This allows overriding the priority of substituters, e.g. $ nix-store --store ~/my-nix/ -r /nix/store/df3m4da96d84ljzxx4mygfshm1p0r2n3-geeqie-1.4 \ --substituters 'http://cache.nixos.org?priority=100 daemon?priority=10' Fixes #3264.

2019-10-29	queryPathInfoUncached(): Return const ValidPathInfo	Eelco Dolstra

2016-06-01	HttpBinaryCacheStore: Fix caching of WantMassQuery	Eelco Dolstra
	Also, test HttpBinaryCacheStore in addition to LocalBinaryCacheStore.
2016-06-01	Make the store directory a member variable of Store	Eelco Dolstra

2016-05-30	Re-implement the WantMassQuery property of binary caches	Eelco Dolstra

2016-04-21	Implement S3BinaryCacheStore::queryAllValidPaths()	Eelco Dolstra
	This allows commands like "nix verify --all" or "nix path-info --all" to work on S3 caches. Unfortunately, this requires some ugly hackery: when querying the contents of the bucket, we don't want to have to read every .narinfo file. But the S3 bucket keys only include the hash part of each store path, not the name part. So as a special exception queryAllValidPaths() can now return store paths without the name part, and queryPathInfo() accepts such store paths (returning a ValidPathInfo object containing the full name).
2016-04-20	Cache path info lookups in SQLite	Eelco Dolstra
	This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
