## Quit (removed)

**Id:** 0<br>
**Introduced:** Nix 0.11<br>
**Removed:** Became dead code in Nix 0.11 and removed in Nix 1.8


## IsValidPath

**Id:** 1<br>
**Introduced:** Nix 0.11<br>

As the name says checks that a store path is valid i.e. in the store.

This is a pretty core operation used everywhere.

### Inputs
path :: [StorePath][se-StorePath]

### Outputs
isValid :: [Bool][se-Bool]


## HasSubstitutes

**Id:** 3<br>
**Introduced:** Nix 0.11<br>

Checks if we can substitute the input path from a substituter. Uses
QuerySubstitutablePaths under the hood :/

### Inputs
path :: [StorePath][se-StorePath]

### Outputs
hasSubstitutes :: [Bool][se-Bool]


## QueryPathHash

**Id:** 4<br>
**Introduced:** Nix 0.11<br>
**Obsolete:** Protocol 1.16, Nix 2.0<br>

Retrieves the base16 NAR hash of a given store path.

### Inputs
path :: [StorePath][se-StorePath]

### Outputs
hash :: [String][se-String] (base16-encoded NAR hash without algorithm prefix)


## QueryReferences

**Id:** 5<br>
**Introduced:** Nix 0.11<br>
**Obsolete:** Protocol 1.16, Nix 2.0<br>

## AddToStore

**Id:** 7<br>
**Introduced:** Nix 0.11<br>

Add a new path to the store.

### Before protocol version 1.25
#### Inputs
- baseName :: [String][se-String]
- fixed :: [Bool64][se-Bool64]
- recursive :: [FileIngestionMethod][se-FileIngestionMethod]
- hashAlgo :: [String][se-String]
- NAR dump

If fixed is `true`, hashAlgo is forced to `sha256` and recursive is forced to
`Recursive`.

Only `Flat` and `Recursive` values are supported for the recursive input
parameter.

#### Outputs
path :: [StorePath][se-StorePath]

### Protocol version 1.25 or newer
#### Inputs
- name :: [String][se-String]
- camStr :: [ContentAddressMethodWithAlgo][se-ContentAddressMethodWithAlgo]
- refs :: [List][se-List] of [StorePath][se-StorePath]
- repairBool :: [Bool64][se-Bool64]
- [Framed][se-Framed] NAR dump

#### Outputs

## AddTextToStore

**Id:** 8<br>
**Introduced:** Nix 0.11<br>
**Obsolete:** Protocol 1.25, Nix 2.4

Add a text file as a store path.

This was obsoleted by adding the functionality implemented by this operation
to [AddToStore](#addtostore). And so this corresponds to calling
[AddToStore](#addtostore) with `camStr` set to `text:sha256` and `text`
wrapped as a NAR.

### Inputs
- suffix :: [String][se-String]
- text :: [Bytes][se-Bytes]
- refs :: [List][se-List] of [StorePath][se-StorePath]

### Outpus
path :: [StorePath][se-StorePath]

**Id:** 9<br>
****Introduced:**** Nix 0.11<br>

Build (or substitute) a list of derivations.

### Inputs

#### Protocol 1.15 or newer
mode :: [BuildMode][se-BuildMode]

Check that connection is trusted before allowing Repair mode.

### Outputs
1 :: [Int][se-Int] (hardcoded)


## EnsurePath

**Id:** 10<br>
**Introduced:** Nix 0.11<br>

Checks if a path is valid. Note: it may be made valid by running a substitute.

### Inputs
path :: [StorePath][se-StorePath]

### Outputs
1 :: [Int][se-Int] (hardcoded)


## AddTempRoot

**Id:** 11<br>
**Introduced:** Nix 0.11<br>

Creates a temporary GC root for the given store path.

Temporary GC roots are valid only for the life of the connection and are used
primarily to prevent the GC from pulling the rug out from under the client and
deleting store paths that the client is actively doing something with.

### Inputs
path :: [StorePath][se-StorePath]

### Outputs
1 :: [Int][se-Int] (hardcoded)


## AddIndirectRoot

**Id:** 12<br>
**Introduced:** Nix 0.11<br>

Add an indirect root, which is a weak reference to the user-facing symlink
created by [AddPermRoot](#addpermroot).

Only ever sent on the local unix socket nix daemon.

### Inputs
path :: [String][se-String]

### Outputs
1 :: [Int][se-Int] (hardcoded)


## SyncWithGC

**Id:** 13<br>
**Introduced:** Nix 0.11<br>
**Obsolete:** Protocol 1.32, Nix 2.5.0

Acquire the global GC lock, then immediately release it.  This function must be
called after registering a new permanent root, but before exiting.  Otherwise,
it is possible that a running garbage collector doesn't see the new root and
deletes the stuff we've just built.  By acquiring the lock briefly, we ensure
that either:

- The collector is already running, and so we block until the
    collector is finished.  The collector will know about our
    *temporary* locks, which should include whatever it is we
    want to register as a permanent lock.
- The collector isn't running, or it's just started but hasn't
    acquired the GC lock yet.  In that case we get and release
    the lock right away, then exit.  The collector scans the
    permanent root and sees ours.

In either case the permanent root is seen by the collector.

Was made obsolete by using [AddTempRoot](#addtemproot) to accomplish the same
thing.


## FindRoots

**Id:** 14<br>
**Introduced:** Nix 0.11<br>

**Obsolete:** Protocol 1.17, Nix 2.0<br>

Older way of adding a store path to the remote store.

It was obsoleted and replaced by AddToStoreNar because it sends the NAR

## BuildDerivation

**Id:** 36<br>
**Introduced:** Protocol 1.14, Nix 1.10<br>

Main build operation used when remote building.

When functioning as a remote builder this operation is used instead of
BuildPaths so that it doesn't have to send the entire tree of derivations
to the remote side first before it can start building. What this does
instead is have a reduced version of the derivation to be built sent as
part of its input and then only building that derivation.

The paths required by the build need to be part of the remote store
(by copying with AddToStoreNar or substituting) before this operation is
called.

### Inputs

## NarFromPath

**Id:** 38<br>
**Introduced:** Protocol 1.17, Nix 2.0<br>

Main way of getting the contents of a store path to the client.

As the name suggests this is done by sending a NAR file.

It replaced the now obsolete ExportPath operation and is used by newer clients to
implement the export functionality for cli. It is also used when remote building
to transfer build results from remote builder to client.

### Inputs
path :: [StorePath][se-StorePath]

### Outputs
NAR dumped straight to the stream.


## AddToStoreNar

- ultimate :: [Bool64][se-Bool64]
- signatures :: [List][se-List] of [String][se-String]

**Id:** 44<br>
**Introduced:** Protocol 1.32*, Nix 2.4<br>

A pipelined version of [AddToStoreNar](#addtostorenar) where you can add
multiple paths in one go.

Added because the protocol doesn't support pipelining and so on a low latency
connection waiting for the request/response of [AddToStoreNar](#addtostorenar)
for each small NAR was costly.

### Inputs
- repair :: [Bool64][se-Bool64]
- dontCheckSigs :: [Bool64][se-Bool64]
- [Framed][se-Framed] stream of add multiple NAR dump


## AddBuildLog

**Id:** 45<br>
**Introduced:** Protocol 1.32, Nix 2.6.0<br>

Attach some build logs to a given build.

### Inputs
- path :: [String][se-String] (might be [BaseStorePath][se-BaseStorePath])
- [Framed][se-Framed] stream of log lines

### Outputs
1 :: [Int][se-Int] (hardcoded)


## BuildPathsWithResults

**Id:** 46<br>
**Introduced:** Protocol 1.34*, Nix 2.8.0<br>

Build (or substitute) a list of derivations and returns a list of results.

### Inputs
- drvs :: [List][se-List] of [DerivedPath][se-DerivedPath]
- mode :: [BuildMode][se-BuildMode]

### Outputs
results :: [List][se-List] of [KeyedBuildResult][se-KeyedBuildResult]


## AddPermRoot

**Id:** 47<br>
**Introduced:** Protocol 1.36*, Nix 2.20.0<br>

### Inputs
- storePath :: [StorePath][se-StorePath]
- gcRoot :: [String][se-String]

### Outputs
gcRoot :: [String][se-String]
