All scripts & documentation is updated for this change.
Added better error messages for global privileges
first pull, merge,test, and get it to work.
The main change is the new replication code - now we have two slave threads
SQL thread and I/O thread. I have also re-written a lot of the code to
prepare for multi-master implementation.
I also documented IO_CACHE quite extensively and to some extend, THD class.
Fixes for building MySQL with gcc 3.0
Added SIGNED / UNSIGNED casts
Fixed core dump bug in net_clear() with libmysqld.
Back to using semaphores in query cache.
Added 'Null' and 'Index_type' to SHOW INDEX.
One more notice:
limiting number of queries per hour for different users has been done
on 4.0.1 , but I can port it to 3.23.*
This will require only certain changes, like number of columns in user
table.
I will also make a test case for it, after it is approved by Monty,
as result file will depend on the error message text.
* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use
I know that all this will require many additions to documentation,
which I have not done, but I am at Arjen's disposal to help him document
all this.
