FakeSsh

class FakeSsh(remoteFiles: Map<String, String> = emptyMap(), remoteEnv: Map<String, String> = emptyMap(), remoteCommands: Map<List<String>, CommandResult> = emptyMap(), uname: String = "Linux x86_64", sshResult: CommandResult? = null, canRun: Boolean = true, val os: String = "macos", val capabilities: Set<Capability> = Capability.entries.toSet(), machines: Map<String, FakeSsh> = emptyMap()) : Host(source)

A local host that answers ssh from a scripted remote, for tests that need a base host for SshHost. sshResult, when set, answers every ssh call (a connection failure, for example); machines answers the calls to a destination with another scripted remote.

Constructors

FakeSsh

Properties

arch

open override val arch: String

capabilities

open override val capabilities: Set<Capability>

open override val os: String

platform

open override val platform: String

ran

val ran: MutableList<List<String>>

Every local command, ssh included.

remoteRan

val remoteRan: MutableList<List<String>>

The words of every remote command, as the remote shell would split them.

Functions

cgroupReading

fun Host.cgroupReading(): CgroupReading?

Null off Linux, without cgroup v2, or when none of the four counters can be read.

env

open override fun env(): Map<String, String>

facts

open fun facts(): List<Attribute>

readText

open override fun readText(path: String): String?

run

open override fun run(argv: List<String>): CommandResult?

open fun run(argv: List<String>, timeoutMillis: Long? = null, onOutput: (String) -> Unit): CommandResult?

Like run, but hands the merged output to onOutput while the process runs. The result carries the exit code and an empty output; the callback has seen all of it. Past timeoutMillis the child is killed and the result carries TIMED_OUT_EXIT_CODE. A host that can measure the child fills CommandResult.usage.

syncNanos

open fun syncNanos(dir: String, rounds: Int): List<Long>?

Nanoseconds per write-and-fsync of a 4 KiB file in dir, or null when the host cannot.
