Check if Task Needs to be Rerun

Source: R/taskTracking.R
shouldRerunTask.Rd

Determines whether a task needs to be rerun by checking:

  1. Task file modifications (file hash comparison)

  2. Dependency file modifications (extracted from source() calls)

  3. Cohort generation changes (hash comparison in database)

  4. Previous run errors (checked in logs and history)

  5. Version changes

Usage

shouldRerunTask(
  taskFile,
  configBlock,
  executionSettings,
  pipelineVersion,
  tasksFolderPath = here::here("analysis/tasks")
)

Arguments

taskFile

Character. Name or path of the task file (e.g., "task1.R")

configBlock

Character. The config block name (e.g., "optum_dod")

executionSettings

tasksFolderPath

Character. Path to tasks folder (default: here::here("analysis/tasks"))

Value

List with elements:

  • should_rerun: Logical. TRUE if task should be rerun

  • reasons: Character vector. Why task should be rerun

  • last_run_info: List with previous run details (time, version, status)

  • task_file_hash: Current hash of task file

  • cohort_hash_status: List comparing manifest hashes to database hashes

Details

Creates/updates exec/logs/task_run_history.csv tracking:

  • task_name, config_block, last_run_time, pipeline_version

  • task_file_hash, cohort_hash_match, status, error_message
