# TEST	recd025
# TEST	Basic tests for transaction bulk loading and recovery.
# TEST	In particular, verify that the tricky hot backup protocol works.

# These tests check the following conditions

# 1. We can abort a TXN_BULK transaction, both online and during recovery.
# 2. Tricky hot backup protocol works correctly
#     - start bulk txn; populate, adding pages
#     - set hotbackup_in_progress (forces chkpt, as bulk txn is in progress)
#     - copy database file
#     - populate more, adding more pages (with bulk optimization disabled)
#     - commit
#     - move copy back into test dir
#     - roll forward, verify rolled-forward backup matches committed database

# A more straightforward test of bulk transactions and hot backup is
# in the backup test.
