# Test organization:

# backup-1.*: Warm-body tests.
#
# backup-2.*: Test backup under various conditions. To and from in-memory
# databases. To and from empty/populated databases. etc.
#
# backup-3.*: Verify that the locking-page (pending byte page) is handled.
#
# backup-4.*: Test various error conditions.
#
# backup-5.*: Test the source database being modified during a backup.
#
# backup-6.*: Test the backup_remaining() and backup_pagecount() APIs.
#
# backup-7.*: Test SQLITE_BUSY and SQLITE_LOCKED errors.
#
# backup-8.*: Test multiple simultaneous backup operations.
#
# backup-9.*: Test that passing a negative argument to backup_step() is
# interpreted as "copy the whole file".
#
# backup-10.*: Test writing the source database mid backup.

# * Target database is empty (zero bytes), OR

# These tests, backup-3.*, ensure that nothing goes wrong if either
# the source or destination database are large enough to include the
# the locking-page (the page that contains the range of bytes that
# the locks are applied to). These tests assume that the pending
# byte is at offset 0x00010000 (64KB offset), as set by tester.tcl,
# not at the 1GB offset as it usually is.
#
# The test procedure is as follows (same procedure as used for
# the backup-2.* tests):
#
# 1) Populate the source database.
# 2) Populate the destination database.
# 3) Run the backup to completion. (backup-3.*.1)
# 4) Integrity check the destination db. (backup-3.*.2)
# 5) Check that the contents of the destination db is the same as that
# of the source db. (backup-3.*.3)
#
# The test procedure is run with the following parameters varied:
#
# * Source database includes pending-byte page.
# * Source database does not include pending-byte page.
#
# * Target database includes pending-byte page.
# * Target database does not include pending-byte page.
#
# * Target database page-size is the same as the source, OR
# * Target database page-size is larger than the source, OR
# * Target database page-size is smaller than the source.

#
# 1) Backing up file-to-file. The writer writes via an external pager.
# 2) Backing up file-to-file. The writer writes via the same pager as
# is used by the backup operation.
# 3) Backing up memory-to-file.
