# pager1-5.1.*: The case where a multi-file cannot be committed because

# another connection is holding a SHARED lock on one of the
|
|
# files. After the SHARED lock is removed, the COMMIT succeeds.
|
|
#
|
|
# pager1-5.2.*: Multi-file commits with journal_mode=memory.
|
|
#
|
|
# pager1-5.3.*: Multi-file commits with journal_mode=memory.
|
|
#
|
|
# pager1-5.4.*: Check that with synchronous=normal, the master-journal file
|
|
# name is added to a journal file immediately after the last
|
|
# journal record. But with synchronous=full, extra unused space
|
|
# is allocated between the last journal record and the
|
|
# master-journal file name so that the master-journal file
|
|
# name does not lie on the same sector as the last journal file
|
|
# record.
|
|
#
|
|
# pager1-5.5.*: Check that in journal_mode=PERSIST mode, a journal file is
|
|
# truncated to zero bytes when a multi-file transaction is
|
|
# committed (instead of the first couple of bytes being zeroed).
