2022-06-23[fixup] handle cache expiration in sqlite queryLinus Heckemann
2022-06-22nar-info-disk-cache: refresh nix-cache-info weeklyLinus Heckemann
This allows changes to nix-cache-info to be picked up by existing clients. Previously, the only way for this to happen would be for clients to delete binary-cache-v6.sqlite, which is quite awkward for users. On the other hand, updates to nix-cache-info should be pretty rare, hence the choice of a fairly long TTL. Configurability is probably not useful enough to warrant implementing it.

2021-05-06Add a realisations disk cacheregnat
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

2020-06-16StorePath: Rewrite in C++Eelco Dolstra
On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB and runtime by 0.8%. This is mostly because we're not parsing the hash part as a hash anymore (just validating that it consists of base-32 characters). Also, replace storePathToHash() by StorePath::hashPart().

This will make it easier to reason about the hash encoding and switch to SRI everywhere where possible.

2019-12-17Add priority setting to storesEelco 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.
2019-12-10Make the Store API more type-safeEelco Dolstra
Most functions now take a StorePath argument rather than a Path (which is just an alias for std::string). The StorePath constructor ensures that the path is syntactically correct (i.e. it looks like <store-dir>/<base32-hash>-<name>). Similarly, functions like buildPaths() now take a StorePathWithOutputs, rather than abusing Path by adding a '!<outputs>' suffix. Note that the StorePath type is implemented in Rust. This involves some hackery to allow Rust values to be used directly in C++, via a helper type whose destructor calls the Rust type's drop() function. The main issue is the dynamic nature of C++ move semantics: after we have moved a Rust value, we should not call the drop function on the original value. So when we move a value, we set the original value to bitwise zero, and the destructor only calls drop() if the value is not bitwise zero. This should be sufficient for most types. Also lots of minor cleanups to the C++ API to make it more modern (e.g. using std::optional and std::string_view in some places).

2018-12-12nar-info-disk-cache: include ca in the cache entriesDaiderd Jordan
Without this information the content addressable state and hashes are lost after the first request, this causes signatures to be required for everything even tho the path could be verified without signing.

2016-04-21Implement 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).

This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
