bitmap_is_set(table->write_set, fiel

Problem: creating a temporary table we allocate the group buffer if needed
followed by table bitmaps (see create_tmp_table()). Reserving less memory for 
the group buffer than actually needed (used) for values retrieval may lead 
to overlapping with followed bitmaps in the memory pool that in turn leads 
to unpredictable consequences.

As we use Item->max_length sometimes to calculate group buffer size,
it must be set to proper value. In this particular case 
Item_datetime_typecast::max_length is too small.

Another problem is that we use max_length to calculate the group buffer
key length for items represented as DATE/TIME fields which is superfluous.

Fix: set Item_datetime_typecast::max_length properly,
accurately calculate the group buffer key length for items 
represented as DATE/TIME fields in the buffer.

Our web server has been restructured several times, and references
to it in our source code has stayed the same.  This patch from Paul
DuBois updates all URLs to modern semantics.

Write .reject file to r/ if it's writable else use opt_logdir 

 - "mysqld --verbose --help" need to be started in a writable directory 

convert(<invalid time>, datetime) in WHERE caused crash as function
returned (void*)NULL, but did not flag SQL NULL. It does now.

Issue a warning if a user sets an option or a variable to a value that is greater than a defined maximum for the option/variable.

This is for bug #29446 "Specifying a myisam_sort_buffer > 4GB on 64 bit machines not possible". Support for myisam_sort_buffer_size > 4 GB on 64-bit Windows will be looked at later in 5.2.

The combination of --single-transaction and --master-data requires
START TRANSACTION WITH CONSISTENT SNAPSHOT which is available from
mysqld 4.1 on. When trying this against an older server, print
diagnostic, then, if --force is not given, abort.

No test-case given since it would require a mysqld < 4.1.

and for bug #31070: crash during conversion of charsets

Problem: passing a 0 byte length string to some my_mb_wc_XXX() 
functions leads to server crash due to improper argument check.

Fix: properly check arguments passed to my_mb_wc_XXX() functions.

Add --skip-innodb-adaptive-hash-index option, which is a way to
work around the bug (by disabling the adaptive hash feature entirely).

This may be useful even once the bug is fixed, for benchmarking purposes.
There are some workloads for which the adaptive hash index is not effective.
