Altering a table with fulltext index[es] which use

branches/5.1: This bug has always existed but was masked by other errors. The
fix for bug# 38839 triggered this bug. When the offset and increment are > 1
we need to calculate the next value taking into consideration the two
variables. Previously we simply assumed they were 1 particularly offset was
never used. MySQL does its own calculation and that's probably why it seemed
to work in the past. We would return what we thought was the correct next
value and then MySQL would recalculate the actual value from that and return
it to the caller (e.g., handler::write_row()). Several new tests have been
added that try and catch some edge cases. The tests exposed a wrap around
error in MySQL next value calculation which was filed as bug 39828. The tests
will need to be updated once MySQL fix that bug.
One good side effect of this fix is that dict_table_t size has been
reduced by 8 bytes because we have moved the autoinc_increment field to
the row_prebuilt_t structure. See review-board for a detailed discussion.

In ha_innobase::info() - do not try to get the free space for a tablespace
which has been discarded with ALTER TABLE ... DISCARD TABLESPACE or if the
.ibd file is missing for some other reason.
ibd_file_missing and tablespace_discarded are manipulated only in
row_discard_tablespace_for_mysql() and in row_import_tablespace_for_mysql()
and the manipulation is protected/surrounded by
row_mysql_lock_data_dictionary()/row_mysql_unlock_data_dictionary() thus we
do the same in ha_innobase::info() when checking the values of those members
to avoid race conditions. I have tested the code-path with UNIV_DEBUG and
UNIV_SYNC_DEBUG.

Bug #38839: auto increment does not work properly with InnoDB after update

branches/5.1: Fix for MySQL Bug#38839. Reset the statement level last
value field in prebuilt. This field tracks the last value in an autoincrement
interval. We use this value to check whether we need to update a table's
AUTOINC counter, if the value written to a table is less than this value
then we avoid updating the table's AUTOINC value in order to reduce
mutex contention. If it's not reset (e.g., after a DELETE statement) then
there is the possibility of missing updates to the table's AUTOINC counter
resulting in a subsequent duplicate row error message under certain
conditions (see the test case for details).

branches/5.1: Fix bug#35537 - Innodb doesn't increment handler_update
and handler_delete
Add the calls to ha_statistic_increment() in ha_innobase::delete_row()
and ha_innobase::update_row().
The test reacted on the way how mtr orders arguments for the server
that are gathered from different source. It appeared that the opt-file
options were parsed before those that supplied to mtr via its command
line. In effect, the opt-file preferences got overriden by the command
line and some tests, like no-threads, were caught by surprise: a test
expects an option value that had been "hardcoded" into its opt-file
but gets another one.
This server options ordering problem exists on in the new rpl trees
mtr. In option of the author of this patch, the opt-file shall be
considered as having the highest preference weight. The opt-file is
merely a part of the header of a test, namely a part that can not be
technically deployed along the test file.
It's unnatural for the test writer to provide both the opt file value
and a guard that guarantees the value will be set on in the run time.
It's logical to provide either one: the option and its value or the
guard.
Fixed with relocating parse of the opt file to be the last among
sources of the sever's options.
A side effect: fixing a small problem of resetting the suite options
at time the opt file starts parsing.
A side effect: main.log_bin_trust_function_creators_func is disabled to
be re-enabled with the fixes for bug#41003 will be merged from the main trees.
mysql-test/lib/mtr_cases.pm:

Fix parsing of mysql client commands, especially in relation to
single-line comments when --comments was specified.
This is a little tricky, because we need to allow single-line
comments in the middle of statements, but we don't want to allow
client commands in the middle of statements. So in
comment-preservation mode, we go ahead and send single-line
comments to the server immediately when we encounter them on their
own.
This is still slightly flawed, in that it does not handle a
single-line comment with leading spaces, followed by a client-side
command when --comment has been enabled. But this isn't a new
problem, and it is quite an edge condition. Fixing it would require
a more extensive overall of how the mysql client parses commands.
