(for example, one of them sets client capabilities by copying server capabilities)

We cannot fix them - let's tolerate them

This can result in bad deadlocks (e.g loader lock), seen in latest crash reports.

since password characters can contain quotes or spaces.

The proper quoting method for command line arguments used here was  extracted from
http://blogs.msdn.com/b/twistylittlepassagesallalike/archive/2011/04/23/everyone-quotes-arguments-the-wrong-way.aspx

Additionally, mysql_install_db.exe now passes root password to "mysqld.exe --bootstrap"
 in hexadecimal form, to handle potential special chars inside password string literal.

        RB-tree index in the MEMORY table fails if it grews over 4G.
        That happened because the old_allocated variable in hp_rb_write_key()
        had the uint type. Changed with the 'size_t' type to be same as the
        'rb_tree.allocated'.

per-file comments:
  storage/heap/hp_write.c
MDEV-80 Memory engine table full at much less than max_heap_table_size with btree index.
        uint->size_t for the 'old_allocated'.

don't cast implicitly an int to a char, when a boolean value is desired.

The main problem was a bug in CSV where it provided wrong statistics (it claimed the table was empty when it wasn't)
I also fixed wrong freeing of blob's in the CSV handler. (Any call to handler::read_first_row() on a CSV table with blobs would fail)



mysql-test/r/csv.result:
  Added new test case
mysql-test/r/partition_innodb.result:
  Updated test results after fixing bug with impossible partitions and const tables
mysql-test/t/csv.test:
  Added new test case
sql/sql_select.cc:
  Cleaned up code for handling of partitions.
  Fixed also a bug where we didn't threat a table with impossible partitions as a const table.
storage/csv/ha_tina.cc:
  Allocate blobroot onces.

Fixed that repair removes the 'table is moved' mark.

mysql-test/suite/maria/r/maria-autozerofill.result:
  Test case for lp:967914
mysql-test/suite/maria/t/maria-autozerofill.test:
  Test case for lp:967914
storage/maria/ha_maria.cc:
  Fixed that repair removes the 'table is moved' mark.

The issue was that check/optimize/anaylze did not zerofill the table before they started to work on it.
Added one more element to not often used function handler::auto_repair() to allow handler to decide when to auto repair.


mysql-test/suite/maria/r/maria-autozerofill.result:
  Test case for lp:944422
mysql-test/suite/maria/t/maria-autozerofill.test:
  Test case for lp:944422
sql/ha_partition.cc:
  Added argument to auto_repair()
sql/ha_partition.h:
  Added argument to auto_repair()
sql/handler.h:
  Added argument to auto_repair()
sql/table.cc:
  Let auto_repair() decide which errors to trigger auto-repair
storage/archive/ha_archive.h:
  Added argument to auto_repair()
storage/csv/ha_tina.h:
  Added argument to auto_repair()
storage/maria/ha_maria.cc:
  Give better error & warning messages for auto-repaired tables.
storage/maria/ha_maria.h:
  Added argument to auto_repair()
  Always auto-repair in case of moved table.
storage/maria/ma_open.c:
  Remove special handling of HA_ERR_OLD_FILE (this is now handled in auto_repair())
storage/myisam/ha_myisam.h:
  Added argument to auto_repair()

lp:933959 Assertion `0' failed in net_end_statement(THD*) on concurrent SELECT FROM I_S.INNODB_SYS_INDEXES and ALTER TABLE

Workaround: report a generic error if an I_S plugin failed silently.

use vsnprintf()
use write() on windows, not WriteFile or fwrite()
localtime_r is still a problem

This bug was introduced into mariadb 5.2 in the December 2010 with
the patch that added a new engine property: the ability to support
virtual columns.    
As a result of this bug the information from frm files for tables 
that contained virtual columns did not appear in the information schema
tables.

Added test case for lp:905782 "Assertion `pageno < ((1ULL) << 40)' failed at ma_pagecache.c:3438: pagecache_read or table corruption on INSERT into a ucs2 table"
The orignal bug has been fixed earlier

If in the where clause of the a query some comparison conditions on the
field under a MIN/MAX aggregate function contained constants whose sizes
exceeded the size of the field then the query could return a wrong result
when the optimizer had chosen to apply the MIN/MAX optimization.
With such conditions the MIN/MAX optimization still could be applied, yet
it would require a more thorough analysis of the keys built to find
the value of MIN/MAX aggregate functions with index look-ups.   
The current patch just prohibits using the MIN/MAX optimization in this
situation.
