NAME [edit section]

= NAME =
allocate_next_batch_id

SYNOPSIS [edit section]

= SYNOPSIS =
Allocate and return the next global batch id for the Fuego system.

DESCRIPTION [edit section]

= DESCRIPTION =
This function reads the global batch_id file for Fuego, and returns it.
It then increments the number and saves it back to the file for the next
allocation operation.

The global batch_id is stored in $FUEGO_RW/logs/next_batch_id, and is
global over all tests.

Using this function will make the batch_id a monotonically increasing
decimal number.

Callers of this function are encouraged to use this global number for
batch tests, but to also prefix the number with a test-specific string,
so that batch_ids are easier for humans to associate with their related
batch tests.
