Details for Bug#43015 main.lock_multi: Weak code (sleeps etc.)
-------------------------------------------------------------
- The fix for bug 42003 already removed a lot of the weaknesses mentioned.
- Tests showed that there are unfortunately no improvements of this tests
in MySQL 5.1 which could be ported back to 5.0.
- Remove a superfluous "--sleep 1" around line 195
Details for Bug#43065 main.lock_multi: This test is too big if the disk is slow
-------------------------------------------------------------------------------
- move the subtests for the bugs 38499 and 36691 into separate scripts
- runtime under excessive parallel I/O load after applying the fix

them is stronger according to coercibility rules,

When loading dump created by mysqldump tool an error is
thrown saying storage engine for the table doesn't have
an option.
mysqldump tries to re-insert the data into the federated
table which causes the error. Since the data is already
available on the remote server, mysqldump shouldn't try
to dump the data again for FEDERATED tables.
As stated in the bug page, it can be considered similar
to the MERGE ENGINE with "view only" nature.
Fixed by adding the "FEDERATED ENGINE" to the exception
list to ignore the data.
client/mysqldump.c:
Fixed check_if_ignore_table() to ignore FEDERATED engine
when dumping the table data.

~40Mb after mysqldump/import
When the input string exceeds the maximum allowed size for the
internal buffer, batch_readline() returns a truncated string.
Since there was no way for a caller to determine whether the
string was truncated or not, the command line client assumed
batch_readline() to always return the whole input string and
appended a newline character. This resulted in garbled data
when importing dumps containing strings longer than the
maximum input buffer size.
Fixed by adding a flag to the batch_readline() interface to
signal a truncated string to the caller.
Other minor problems fixed during patch implementation:
- The maximum allowed buffer size for batch_readline() was set
up depending on the client's max_allowed_packet value. It does
not actully make any sense, as those variables are not
related. The input buffer size limit is now always set to 1
MB.
- fill_buffer() did not always set the EOF flag.
- The input buffer could actually grow twice as the specified
limit due to insufficient checks in intern_read_line().
client/my_readline.h:
Changed the interface of batch_readline().
client/mysql.cc:
Honor the truncated flag returned by batch_readline() and do
not append the newline character if it was set. Since we can't
change the interfaces for readline()/fgets() used in the
interactive mode, always assume the returned string was not
truncated. In addition, always set the batch_readline()
internal buffer to 1 MB, independently from the client's
max_allowed_packet.
client/readline.cc:
Added the 'truncated' argument do batch_readline() to signal
truncated string to a caller.
Fixed fill_buffer() to set the EOF flag correctly.
Fixed checks in intern_read_line() to not allow the internal
buffer grow past the specified limit.

Any statement reading corrupt archive data file
(CHECK/REPAIR/SELECT/UPDATE/DELETE) may cause assertion
failure in debug builds. This assertion has been removed
and an error is returned instead.
Also fixed that CHECK/REPAIR returns vague error message
when it mets corruption in archive data file. This is
fixed by returning proper error code.

- merged the fix to 5.1
- extended to cover I_S.PROCESSLIST.TIME
- Changed the column type of I_S.PROCESSLIST.TIME from LOGNLONG
UNSIGNED
to LONG (to match the SHOW PROCESSLIST type)
- Added a test case
If a sys-var has a base and a block-size>1, and then a
user-supplied value >= minimum ended up below minimum
thanks to block-size alignment, we threw a warning.
This meant for instance that when getting, then setting
the minimum, we'd see a warning. This was needlessly
confusing. (updated patch)
select where .. (col=col and col=col) or ... (false expression)
Problem: optimizer didn't take into account a singular case
when we eliminated all the predicates at the AND level of WHERE.
That may lead to wrong results.
Fix: replace (a=a AND a=a...) with TRUE if we eliminated all the
predicates.

Fix for bug #42957: no results from

sql/sql_select.cc:
Fix for bug #42957: no results from
select where .. (col=col and col=col) or ... (false expression)
- replacing equality predicates by multiple equality items check
if we eliminate all the predicates at the AND level and
replace them with TRUE if so.
Bug #43203 Overflow from auto incrementing causes server segv

branches/5.1: Bug#43203: Overflow from auto incrementing causes server segv
It was not a SIGSEGV but an assertion failure. The assertion was checking
the invariant that *first_value passed in by MySQL doesn't contain a value
that is greater than the max value for that type. The assertion has been
changed to a check and if the value is greater than the max we report a
generic AUTOINC failure.

Bug #42714 AUTO_INCREMENT errors in 5.1.31
Detailed revision comments:
r4287 | sunny | 2009-02-25 05:32:01 +0200 (Wed, 25 Feb 2009) | 10 lines
branches/5.1: Fix Bug#42714 AUTO_INCREMENT errors in 5.1.31. There are two
changes to the autoinc handling.
1. To fix the immediate problem from the bug report, we must ensure that the
value written to the table is always less than the max value stored in
dict_table_t.
2. The second related change is that according to MySQL documentation when
the offset is greater than the increment, we should ignore the offset.
Bug #42400 InnoDB autoinc code can't handle floating-point columns

branches/5.1: In the last round of AUTOINC cleanup we assumed that AUTOINC
is only defined for integer columns. This caused an assertion failure when
we checked for the maximum value of a column type. We now calculate the
max value for floating-point autoinc columns too.

Since there is more than one duplicate value in the table, when adding the
unique index it is not deterministic which value will be reported as causing a
problem. Replace the reported value with '' so that it doesn't affect the
results.
