Module execution_chain 

Continuation chains (issue #231): a launch with --continues <id> stores the UUID it continues, so a supervisor that relaunches fresh instead of --resume-ing in place can still treat every execution of one task as a whole. --status prints the chain and --upload-log uploads one file with every execution of it, oldest first.

Structs

ChainLog

A temporary combined log, removed when dropped.

Functions

build_chain

Records of the chain record belongs to, oldest first. Backward links come from continues; forward, the most recently started record that continues the current one is followed. Cycles stop the walk.

identity_text_lines

Text-format lines for the identity fields of a status record.

prepare_chain_upload

Combined log --upload-log uploads for record when it belongs to a chain of more than one execution; None for a single execution.

resolve_continues

Resolve --continues <id> for a new launch to the UUID it stores.

status_identity

Fields --status reports right after uuid: the names the execution answers to (aliases, once --alias/--rename gave it one) and its continuation chain, when it has more than one member.

write_chain_log

Concatenate the logs of a chain into one temporary file, oldest first, each preceded by a lifecycle header in the format --resume writes.
