2020-10-07Serialize exceptions from the daemon to the clientEelco Dolstra
2020-10-06Remove static variable name clashesEelco Dolstra
This was useful for an experiment with building Nix as a single compilation unit. It's not very useful otherwise but also doesn't hurt...

2020-09-30Revert "Use template structs instead of phantoms"John Ericson
This reverts commit 9ab07e99f527d1fa3adfa02839da477a1528d64b.

2020-09-22RemoteStore::addCAToStore(): Don't hold connection while calling queryPathInfo()Eelco Dolstra
This leads to a deadlock if we're at the connection limit.

2020-09-21Move Callback into its own headerEelco Dolstra
This gets rid of the inclusion of <future> in util.hh, cutting compilation time by ~20s (CPU time). Issue #4045.
2020-09-21wopAddToStore: return ValidPathInfoRobert Hensing
A ValidPathInfo is created anyway. By returning it we can save a roundtrip and we have a nicer interface.

2020-09-16Fix build issues with gccregnat
2020-09-16Document the new store hierarchyregnat
2020-09-16Properly filter the stores according to their declared uriSchemesregnat
When opening a store, only try the stores whose `uriSchemes()` include the current one
2020-09-16Correctly call all the parent contructors of the storesregnat
Using virtual inheritance means that only the default constructors of the parent classes will be called, which isn't what we want
2020-09-16Separate store configs from the implemsregnat
Rework the `Store` hierarchy so that there's now one hierarchy for the store configs and one for the implementations (where each implementation extends the corresponding config). So a class hierarchy like ``` StoreConfig-------->Store | | v v SubStoreConfig----->SubStore | | v v SubSubStoreConfig-->SubSubStore ``` (with virtual inheritance to prevent DDD). The advantage of this architecture is that we can now introspect the configuration of a store without having to instantiate the store itself
2020-09-16Fix the registration of storesregnat
2020-09-16Make the store plugins more introspectableregnat
Directly register the store classes rather than a function to build an instance of them. This gives the possibility to introspect static members of the class or choose different ways of instantiating them.

2020-09-15gracefully handle old daemon versionsregnat
Add a fallback path in `queryPartialDerivationOutputMap` for daemons that don't support it. Also upstreams a couple methods from `SSHStore` to `RemoteStore` as this is needed to handle the fallback path.
2020-09-13Fix unspecified behaviour in readStorePathCAMapaszlig
When deploying a Hydra instance with current Nix master, most builds would not run because of errors like this: queue monitor: error: --- Error --- hydra-queue-runner error: --- UsageError --- nix-daemon not a content address because it is not in the form '<prefix>:<rest>': /nix/store/...-somedrv The last error message is from parseContentAddress, which expects a colon-separated string, however what we got here is a store path. Looking at the worker protocol, the following message sent to the Nix daemon caused the error above: 0x1E -> wopQuerySubstitutablePathInfos 0x01 -> Number of paths 0x16 -> Length of string "/nix/store/...-somedrv" 0x00 -> Length of string "" Looking at writeStorePathCAMap, the store path is indeed the first field that's transmitted. However, readStorePathCAMap expects it to be the *second* field *on my machine*, since expression evaluation order is a classic form of unspecified behaviour[1] in C++. This has been introduced in https://github.com/NixOS/nix/pull/3689, specifically in commit 66a62b3189c8c9b0965850e6b3c9b0fda0b50fd8.

2020-08-27RemoteStore::addToStore(): Fix race between stderrThread and NAR writerEelco Dolstra
As pointed out by @B4dM4n, the call to to.flush() on stderrThread is unsafe because the NAR writer thread is also writing to 'to'. Fixes #3943.

`queryDerivationOutputMap` no longer assumes all outputs have a mapping

- `queryDerivationOutputMapAssumeTotal` -> `queryPartialDerivationOutputMap` - `queryDerivationOutputMapAssumeTotal` -> `queryDerivationOutputMap`
2020-08-19Use `RemoteStore` to open connection for proxying daemonJohn Ericson
Removes duplicate websocket opening code, and also means we should be able to to ssh-ssh-... daemon relays, not just uds-uds-... ones.

While I am cautious to break parametricity, I think it's OK in this cases---we're not about to try to do some crazy polymorphic protocol anytime soon.
