says * for global allowed
The current behaviour of 'GRANT *' was changed as a part of the fix
for Bug#19022, Bug#17199 and Bug#18444. To avoid regression, we keep
the current behavior and update the documentation.
Test case added to grant.test.
covering index
When two range predicates were combined under an OR
predicate, the algorithm tried to merge overlapping ranges
into one. But the case when a range overlapped several other
ranges was not handled. This lead to
1) ranges overlapping, which gave repeated results and
2) a range that overlapped several other ranges was cut off.
Fixed by
1) Making sure that a range got an upper bound equal to the
next range with a greater minimum.
2) Removing a continue statement
lowercasing table name".
In lower_case_table_names > 0 mode some queries to I_S left entries
with incorrect key in table definition cache. This wasted memory and
caused some of the further queries to I_S to produce stale results
in cases when table definition was changed by a DDL statement.
Also in combination with similar problem in CREATE TABLE (which also
has peeked into table definition cache using non-normalized key) this
issue led to to spurious ER_TABLE_EXISTS_ERROR errors when one tried
to create a table with the same name as a previously existing but
dropped table (assuming that table name contained characters in upper
case).
This problem occured due to fact that fill_schema_table_from_frm()
was not properly normalizing (lowercasing) database and table names
which it used for lookups in table definition cache.
This fix adds proper normalization to this function. It also solves
similar problem in CREATE TABLE's code by ensuring that it uses
properly normalized version of table name when it peeks into table
definition cache instead of non-normalized one.

is reached
Problem was bad error handling, leaving some new temporary
partitions locked and initialized and some not yet initialized
and locked, leading to a crash when trying to unlock the not
yet initialized and locked partitions
Solution was to unlock the already locked partitions, and not
include any of the new temporary partitions in later unlocks
can lead to bad memory access
Problem: Field_bit is the only field which returns INT_RESULT
and doesn't have unsigned flag. As it's not a descendant of the
Field_num, so using ((Field_num *) field_bit)->unsigned_flag may lead
to unpredictable results.
Fix: check the field type before casting.

Detailed revision comments:
r5703 | marko | 2009-08-27 02:25:00 -0500 (Thu, 27 Aug 2009) | 41 lines
branches/zip: Replace the constant 3/8 ratio that controls the LRU_old
size with the settable global variable innodb_old_blocks_pct. The
minimum and maximum values are 5 and 95 per cent, respectively. The
default is 100*3/8, in line with the old behavior.
ut_time_ms(): New utility function, to return the current time in
milliseconds. TODO: Is there a more efficient timestamp function, such
as rdtsc divided by a power of two?
buf_LRU_old_threshold_ms: New variable, corresponding to
innodb_old_blocks_time. The value 0 is the default behaviour: no
timeout before making blocks 'new'.
bpage->accessed, bpage->LRU_position, buf_pool->ulint_clock: Remove.
bpage->access_time: New field, replacing bpage->accessed. Protected by
buf_pool_mutex instead of bpage->mutex. Updated when a page is created
or accessed the first time in the buffer pool.
buf_LRU_old_ratio, innobase_old_blocks_pct: New variables,
corresponding to innodb_old_blocks_pct
buf_LRU_old_ratio_update(), innobase_old_blocks_pct_update(): Update
functions for buf_LRU_old_ratio, innobase_old_blocks_pct.
buf_page_peek_if_too_old(): Compare ut_time_ms() to bpage->access_time
if buf_LRU_old_threshold_ms && bpage->old. Else observe
buf_LRU_old_ratio and bpage->freed_page_clock.
buf_pool_t: Add n_pages_made_young, n_pages_not_made_young,
n_pages_made_young_old, n_pages_not_made_young, for statistics.
buf_print(): Display buf_pool->n_pages_made_young,
buf_pool->n_pages_not_made_young. This function is only for crash
diagnostics.
buf_print_io(): Display buf_pool->LRU_old_len and quantities derived
from buf_pool->n_pages_made_young, buf_pool->n_pages_not_made_young.
This function is invoked by SHOW ENGINE INNODB STATUS.

branches/zip: Fix a critical bug in fast index creation that could
corrupt the created indexes.
row_merge(): Make "half" an in/out parameter. Determine the offset of
half the output file. Copy the last blocks record-by-record instead of
block-by-block, so that the records can be counted. Check that the
input and output have matching n_rec.
row_merge_sort(): Do not assume that two blocks of size N are merged
into a block of size 2*N. The output block can be shorter than the
input if the last page of each input block is almost empty. Use an
accurate termination condition, based on the "half" computed by
row_merge().
row_merge_read(), row_merge_write(), row_merge_blocks(): Add debug output.
merge_file_t, row_merge_file_create(): Add n_rec, the number of records
in the merge file.
row_merge_read_clustered_index(): Update n_rec.
row_merge_blocks(): Update and check n_rec.
row_merge_blocks_copy(): New function, for copying the last blocks in
row_merge(). Update and check n_rec.
This bug was discovered with a user-supplied test case that creates an
index where the initial temporary file is 249 one-megabyte blocks and
the merged files become smaller. In the test, possible merge record
sizes are 10, 18, and 26 bytes.

Done away with following two status variables:
innodb_buffer_pool_read_ahead_rnd
innodb_buffer_pool_read_ahead_seq
Introduced two new status variables:
innodb_buffer_pool_read_ahead = number of pages read as part of
readahead since server startup
innodb_buffer_pool_read_ahead_evicted = number of pages that are read
in as readahead but were evicted before ever being accessed since
server startup i.e.: a measure of how badly our readahead is
performing
SHOW INNODB STATUS will show two extra numbers in buffer pool section:
pages read ahead/sec and pages evicted without access/sec

A fix for Bug#26704: Failing DROP DATABASE brings
mysql-client out of sync.
The problem was that we changed current database w/o caring
whether it was dropped successfully or not.
The fix is not to change current database if we failed to drop it.
The issue appears when number of heartbeat events non-zero before start of test
block. But really we need to check that no new events has received during test block.
So I did following:
1. Replace absolute values by diff of values
2. Increase heartbeat period from 1.5 to 5 sec
buffering is used
FORCE INDEX FOR ORDER BY now prevents the optimizer from
using join buffering. As a result the optimizer can use
indexed access on the first table and doesn't need to
sort the complete resultset at the end of the statement.
