The UNIV_DEBUG version asserted if a foreign key check failed because of a lock wait timeout
btr0cur.c:
Fix a bug: if the primary key was updated (or delete + insert) so that only the case of characters changed, we were left with a dangling adaptive hash index pointer, often causing an assertion failure in page0page.ic line 515
Add some diagnostic code to track BLOB bugs if they were not already fixed with the change in row0sel.c
row0sel.c:
Fix a seg fault which was caused inside MySQL because InnoDB when returning a BLOB value did not initialize the length and the data pointer of a BLOB whose value is the SQL NULL; also fix a very improbable race condition which could occur if a row with an externally stored BLOB was fetched using the adaptive hash index
Small improvements
row0mysql.c:
Small improvements + fix the ALTER TABLE problem by introducing a lazy drop table it can use
ha_innobase.cc:
Some fine-tuning of optimization
Do less statistics calculations for tables
dict0mem.h, row0mysql.c:
Make calculation of new statistics less frequent, because the statistics in 3.23.44 involves many random disk reads
Made innodb to compile more cleanly with debugging options
enabled. Fixed a few bugs and found a few possible bugs, which
I hope Heikki will check. Comments needs to be fixed too. Some
while() functions should be changed to do ... until for documenting
purposes, because some of them must and will be processed at least
once, or a variable would be used uninitialized.

Jani
