# Bug#14007109 RECURSIVE ACQ OF BLOCK LOCK IN S MODE, STATS UPDATE ASRT !RW_LOCK_OWN(LOCK, 352)

# As of the time this test is added, 854 pages do not trigger the assert,

# is to have a btree with 3 levels, where the level in the middle contains
|
|
# two (or more) pages. The persistent stats code crawls that level twice
|
|
# in the same mtr:
|
|
# dict_stats_analyze_index()
|
|
# start mtr
|
|
# dict_stats_analyze_index_level(mtr)
|
|
# traverse the level (leaves the last page in the middle level S-latched)
|
|
# dict_stats_analyze_index_for_n_prefix(mtr)
|
|
# traverse the level (would try to S-latch the last page)
|

# commit mtr
