task_reset: Reset Task Status to Idle

Description

Resets tasks with specified statuses back to idle (NULL) state, clearing their execution history. This allows them to be picked up by workers again.

Usage

task_reset(project, status = c("working", "failed"), con = NULL)

Value

Invisibly returns NULL. Called for side effects (resetting task status).

Arguments

project

Character string specifying the project name.

status

Character vector of statuses to reset. Can include "working", "failed", "finished", or "all". Default is c("working", "failed").

con

An optional database connection. If NULL, a new connection is created and closed automatically.

Details

Resetting tasks clears:

• Status (set to NULL/idle)

• Start time

• Finish time

• Error messages

Common use cases:

• Reset failed tasks after fixing code: status = "failed"

• Reset interrupted tasks: status = "working"

• Re-run everything: status = "all"

Specifying status = "all" resets all tasks regardless of current status.

# Reset all tasks to start over
