# Test cases autovacuum-1.* work as follows:
|
|
#
|
|
# 1. A table with a single indexed field is created.
|
|
# 2. Approximately 20 rows are inserted into the table. Each row is long
|
|
# enough such that it uses at least 2 overflow pages for both the table
|
|
# and index entry.
|
|
# 3. The rows are deleted in a psuedo-random order. Sometimes only one row
|
|
# is deleted per transaction, sometimes more than one.
|
|
# 4. After each transaction the table data is checked to ensure it is correct
|
|
# and a "PRAGMA integrity_check" is executed.
|
|
# 5. Once all the rows are deleted the file is checked to make sure it
|
|
# consists of exactly 4 pages.
|
|
#
|
|
# Steps 2-5 are repeated for a few different psuedo-random delete patterns
|
|
# (defined by the $delete_orders list).

# the free root-page location.

# autovacuum-2.4.*: Check that a table can be created correctly when the
|
|
# root-page it requires is on the free-list.

# In autovacuum mode, when tables or indices are deleted, the rootpage
|
|
# values in the symbol table have to be updated. There was a bug in this
|
|
# logic so that if an index/table was moved twice, the second move might
|
|
# not occur. This would leave the internal symbol table in an inconsistent
|
|
# state causing subsequent statements to fail.
|
|
#
|
|
# The problem is difficult to reproduce. The sequence of statements in
|
|
# the following test are carefully designed make it occur and thus to
|
|
# verify that this very obscure bug has been resolved.
