2024-06-23libutil: remove sinkToSource eof callbackeldritch horrors
this is only used in one place, and only to set a nicer error message on EndOfFile. the only caller that actually *catches* this exception should provide an error message in that catch block rather than forcing support for setting error message so deep into the stack. copyStorePath is never called outside of PathSubstitutionGoal anyway, which catches everything.

2024-06-19libutil: return a source from readFileeldritch horrors
don't consume a sink, return a source instead. the only reason to not do this is a very slight reduction in dynamic allocations, but since we are going to *at least* do disk io that will not be a lot of overhead anyway Change-Id: Iae2f879ec64c3c3ac1d5310eeb6a85e696d4614a
2024-06-18libstore: fix queryValidPaths concurrencyJade Lovelace
The lock usage was obviously wrong so it was entirely serialized. This has the predicted speedups, the only question is whether it is sound because it's exposing a bunch of new code to actual concurrency. I did audit all the stores' queryPathInfoUncached implementations and they all look *intended* to be thread safe, but whether that is actually sound or not: lol lmao. I am highly confident in the s3 one because it is calling s3 sdk methods that are thread safe and has no actual state. Others are using Pool and look to be *supposed* to be thread safe, but unsure if they actually are. Change-Id: I0369152a510e878b5ac56c9ac956a98d48cd5fef

2024-06-16Harmonise the Store::queryPathInfoUncached interfacejulia
This: - Consistently returns `nullptr` for a non-existent store path, instead of a mix of `nullptr` and throwing exceptions. - If a store returns "bad" store paths in response to a request (e.g. incorrect hash or name), don't cache this result. This removes some duplication of code at the cache-access layer of queryPathInfo() checking this, and ­allows us to provide more specific errors. Part of #270.

2024-05-10libutil: remove callback.hheldritch horrors
it's no longer used. it really shouldn't have existed this long since it was just a mashup of both std::promise and std::packaged_task in a shape that makes composition unnecessarily difficult. all but a single case of Callback pattern calls were fully synchronous anyway, and even this sole outlier was by far not important enough to justify the extra complexity.

2024-05-06fix fallback chroot store creation after b247ef72dQyriad
When /nix/var (or, more precisely, NIX_STATE_DIR) does not exist at all, Lix falls back to creating an adhoc chroot store in XDG_DATA_HOME. b247ef72d[1] changed the way Store classes are initialized, and in the migration, a `params2` was accidentally changed to `params`. This commit restores the correct behavior, and in lieu of a single *character* fix, this commit also changes the variable name to something more reasonable. Fixes #274. [1]: b247ef72dc7bcc857288c0ddcceb3e42f76a78f1 n.b., this code might deserve some more looking at anyway. this fallback store creation throws away *all* Store params passed to openFromNonUri() in favor of an entirely new set which only contains the `root` param, which may or may not be the correct behavior Change-Id: Ibea559b88a50e6d6e75a1f87d9d7816cabb2a8f3

2024-04-23libstore: Create platform LocalStore subclassesArtemis Tosini
This creates new subclasses of LocalStore for each OS to include platform-specific functionality. Currently this just includes garbage collector roots but it could be extended to sandboxing as well. In order to make sure that the generic LocalStore is not accidentally constructed, its constructor is protected. A Fallback is provided which implements no functionality except constructors.

obsidiansystems/queryPartialDerivationOutputMap-evalStore Give `queryPartialDerivationOutputMap` an `evalStore` parameter
2023-07-20Give `queryPartialDerivationOutputMap` an `evalStore` parameterJohn Ericson
This makes it more useful. In general, the derivation will be in one store, and the realisation info is in another. This also helps us avoid duplication. See how `resolveDerivedPath` is now simpler because it uses `queryPartialDerivationOutputMap`. In #8369 we get more flavors of derived path, and need more code to resolve them all, and this problem only gets worse. The fact that we need a new method to deal with the multiple dispatch is unfortunate, but this generally relates to the fact that `Store` is a sub-par interface, too bulky/unwieldy and conflating separate concerns. Solving that is out of scope of this PR. This is part of the RFC 92 work. See tracking issue #6316
2023-07-07Simplify `ContentAddress`John Ericson
Whereas `ContentAddressWithReferences` is a sum type complex because different varieties support different notions of reference, and `ContentAddressMethod` is a nested enum to support that, `ContentAddress` can be a simple pair of a method and hash. `ContentAddress` does not need to be a sum type on the outside because the choice of method doesn't effect what type of hashes we can use.

2023-04-02Move `querySubstitutablePathInfos` from `LocalStore` to `Store`John Ericson
The code is not local-store-specific, so we should share it with all stores. More uniform behavior is better, and a less store-specific functionality is more maintainable. This fixes a FIXME added in f73d911628 by @edolstra himself.
