tar_unblock_process: Unblock the pipeline process

In targets: Dynamic Function-Oriented 'Make'-Like Declarative Pipelines

Unblock the pipeline process

Description

targets tries to avoid running two concurrent instances of tar_make() on the same pipeline writing to the same data store. Sometimes it generates false positives (meaning tar_make() throws this error even though there is only one instance of the pipeline running.) If there is a false positive, tar_unblock_process() gets the pipeline unstuck by removing the ⁠_targets/meta/process⁠ file. This allows the next call to tar_make() to resume.

Usage

tar_unblock_process(store = targets::tar_config_get("store"))

Arguments

store

Character string, path to the data store (usually "_targets").

Value

NULL (invisibly). Called for its side effects.
