def files (dir: String) (regexp: RegExp): List String

Find files WARNING! Use of this method can make a build unreproducible. Depending on when the method is invoked, the results may vary! This method is intended to be used by the outputFn of localRunner Jobs.

Parameters: dir: String,  regexp: RegExp

Return Type: List String

def source (file: String): Result Path Error

No description for this feature yet.

Parameters: file: String

Return Type: Result Path Error

def claim (file: String): Result Path Error

Allows claiming of a file so long as the file is within wake’s workspace. Keep in mind that if another job produced this file in the same run of wake, claim will fail. Likewise if you claim a file then any job that produces this file will fail. Claim should be thought of as a “virtual” job and wake demands that all paths be produced by exactly one job, virtual or otherwise.

For source files please use source. For files outside of wake’s workspace please use claimFileAsPath or claimFileAsPathIn. claim is good for claiming artifacts of previous builds that should not be rebuilt during this run.

Parameters: - file: The string giving the path to the file to be claimed

Example: ` claim "build/my_flow/my_step/previous-output.txt" # Claims the file `

Parameters: file: String

Return Type: Result Path Error

def sources (dir: String) (filterRegexp: RegExp): Result (List Path) Error

Parameters: dir: String,  filterRegexp: RegExp

Return Type: Result (List Path) Error

def claimFileAsPath (existingFile: String) (desiredWorkspacePath: String): Result Path Error

Return Type: Result Path Error

def claimFileAsPathIn (outputDirectory: Path) (existingFile: String) (desiredName: String): Result Path Error

Return Type: Runner

def makeRunner (name: String) (run: Job

makeRunner: Hides some of the boiler plate required to create a runner

This function requires very advanced wake experience and should be used with the greatest amount of caution. Callers must ensure at the very least that run calls primJobLaunch and one of the many job “wait” functions. Historically runners allowed dispatching to an arbirary “base” or “inner” runner. This significantly complicated the system and led to very unexpected interactions. It is recomennded that runners don’t accept an “inner” runner and instead directly call the job primatives. If wrapping is unavoidable then the specific runner being wrapped should be named instead of accepting an arbitrary runner parameter.

localRunner is a good reference implementation of the run function.

Parameters: name: String,  run: Job,  RunnerInput,  Result RunnerOutput Error

Return Type: Runner

def wrapRunner name pre post (Runner _ run)

wrapRunner: Deprecated. Do not use this function.

It will be deleted in the next release. See makeRunner for migration

def getJobFailedStderrRaw (job: Job): Result String Error

Gives the full stderr of a job as a string, without any manipulation. Returns the result successfully as long as the job was successfully launched and closed its stderr handle at some point during its execution. This generally occurs by the process simply terminating. The only case in which this would return a failure is if the job did not successfully launch.

Parameters: job: Job

Return Type: Result String Error

def getJobStdout (job: Job): Result String Error

Gives the job’s stdout if the job exited with an exit code of zero. The output will be manipulated to not contain ANSI escape codes.

Parameters: job: Job

def unsafe_getJobRunnerOutput (job: Job): Result String Error

Get the runner output from a job. Runner output is separate from job stdout and is used by the runner infrastructure to report information about how the job was executed, rather than output from the job itself. These reportings are communicated via the fd3 stream, which runner scripts can write to inorder to report information to Wake. Result returns an empty string if there is no runner output, and is also stored in the Wake db. Since runner outputs are not cached, a cached result will have an empty runner output.

Marked unsafe as Runner output is not cached and cannot guarantee reproduciblity.

Parameters: job: Job

Return Type: Result String Error

def unsafe_getJobRunnerError (job: Job): Result String Error

Get the runner error from a job. Runner error is separate from job stderr and is used by the runner infrastructure to report errors that occurred while trying to execute the job, rather than errors from the job itself. Runner scripts as well as runners can write to the fd4 stream to report errors. Result returns an empty string if there is no runner error, and is also stored in the Wake db. Since runner errors are not cached, a cached result will have an empty runner error.

Marked unsafe as Runner error is not cached and cannot guarantee reproduciblity.

Parameters: job: Job

Return Type: Result String Error

def unsafe_reportJobRunnerOutput (job: Job) (output: String): Job

Report a runner output for a job. This is used to report out runner infrastructure information observed from Wake. Similar to runner scripts, runners themselves can write to the fd3 stream to report information via this function. Multiple calls to this function for a specific job will append to the runner output message that is saved to the Wake db.

Marked unsafe as this function should only be called for over-the-wall reporting for runners and because of its uncacheablity as runner outputs are not cached.

Parameters: job: Job,  output: String

Return Type: Job

def unsafe_reportJobRunnerError (job: Job) (error: String): Job

Report a runner error for a job. This is used to report out runner infrastructure errors observed from Wake. Similar to runner scripts, runners themselves can write to the fd4 stream to report errors via this function. Multiple calls to this function for a specific job will append to the runner error message that is saved to the Wake db.

Marked unsafe as this function should only be called for over-the-wall reporting for runners and because of its uncacheablity as runner errors are not cached.

Parameters: job: Job,  error: String

Return Type: Job

def unsafe_primJobSetRunnerStatus (job: Job) (status: Integer): Unit

Set a runner status for a job The runner status code is used to determine if the runner that a job ran on succeeded (0) or failed (> 0). Since runner status is not inherrient to a jobs execution, runners should manually set the status through this out-of-band mechanism for both Wake related reporting as well as for runner scripts that are considered to be an extension of the runner. A job’s runner status is default set to be 0.

Marked unsafe as this function should only be called for over-the-wall reporting for runners and because of its uncacheablity as runner status is not cached.

Parameters: job: Job,  status: Integer

Return Type: Unit

def unsafe_getJobRunnerStatus (job: Job): Result Integer Error

Get the runner status from a job. The runner status code is used to determine if the runner that a job ran on succeeded (0) or failed (> 0). Jobs that have a failed runner status are not cached.

Marked unsafe as Runner status is not cached and cannot guarantee reproduciblity.

Parameters: job: Job

Return Type: Result Integer Error

def unsafe_reportJobRunnerFailure (job: Job) (error: String) (status: Integer): Job

Report a runner error and set runner status for a job. This is a convenience function that calls both makeJobRunnerError and unsafe_primJobSetRunnerStatus. This function is also utilized by primJobFailLaunch to report runner errors before a job is launched.

Marked unsafe as this function should only be called for over-the-wall reporting for runners and because of its uncacheablity as runner errors and runner status are not cached.
