# The basic test structure here is that we write a lot of log

# records (enough to fill up 100 log files; each log file it
|
|
# small). We start with three txns and open a database in
|
|
# each transaction. Then, in a loop, we take periodic
|
|
# checkpoints. Between each pair of checkpoints, we end one
|
|
# transaction; when no transactions are left, we start up three
|
|
# new ones, letting them overlap checkpoints as well.
|
|
#
|
|
# The pattern that we create is:
|
|
# 1. Create TXN1, TXN2, TXN3 and open dbs within the txns.
|
|
# 2. Write a bunch of additional log records.
|
|
# 3. Checkpoint.
|
|
# 4. Archive, checking that we list the right files.
|
|
# 5. Commit one transaction.
|
|
# 6. If no txns left, start 3 new ones.
|
|
# 7. Until we've gone through enough records, return to step 2.
