Bug#53417 my_getwd() makes assumptions on the buffer sizes which not always hold true
The mysys library contains many functions for rewriting file paths. Most of these
functions makes implicit assumptions on the buffer sizes they write to. If a path is put
in my_realpath() it will propagate to my_getwd() which assumes that the buffer holding
the path name is greater than 2. This is not true in cases.
In the special case where a VARBIN_ITEM is passed as argument to the LOAD_FILE function
this can lead to a crash.
This patch fixes the issue by introduce more safe guards agaist buffer overruns.
Iterative patch improvement. Previously committed patch
caused wrong result on Windows. The previous patch also
broke secure_file_priv for symlinks since not all file
paths which must be compared against this variable are
normalized using the same norm.
The server variable opt_secure_file_priv wasn't
normalized properly and caused the operations
LOAD DATA INFILE .. INTO TABLE ..
and
SELECT load_file(..)
to do different interpretations of the
--secure-file-priv option.
The patch moves code to the server initialization
routines so that the path always is normalized
once and only once.
It was also intended that setting the option
to an empty string should be equal to
lifting all previously set restrictions. This
is also fixed by this patch.

Correcting a patch misstake. The converted file path is placed in 'buff' not in opt_secure_file_priv.
mysql-test/r/loaddata.result:
* Updated test case; Since secure_file_priv now is normalized the previous values are changed.
sql/mysqld.cc:
* Fixed patch misstake
The server variable opt_secure_file_priv wasn't
normalized properly and caused the operations
LOAD DATA INFILE .. INTO TABLE ..

Repairing MyISAM table with fulltext indexes and low
myisam_sort_buffer_size may crash the server.
Estimation of number of index entries was done incorrectly,
causing further assertion failure or server crash.
Docs note: min value for myisam_sort_buffer_size has been
changed from 4 to 4096.
mysql-test/r/fulltext.result:
A test case for BUG#51866.
mysql-test/r/myisam.result:
Min value for myisam_sort_buffer_size is 4096.
mysql-test/r/variables.result:
Min value for myisam_sort_buffer_size is 4096.
mysql-test/suite/sys_vars/r/myisam_sort_buffer_size_basic_32.result:
Min value for myisam_sort_buffer_size is 4096.
mysql-test/t/fulltext.test:
A test case for BUG#51866.
sql/mysqld.cc:
Min value for myisam_sort_buffer_size is 4096.
storage/myisam/mi_check.c:
When estimating number of index entries for external
fulltext parser, take into account that key_length may
be bigger than myisam_sort_buffer_size. Reuse logic
from _create_index_by_sort(): force MIN_SORT_BUFFER to
be min value for myisam_sort_buffer_size.
Another problem is that ftkey_nr has no other meaning
than serial number of fulltext index starting with 1.
We can't say if this key using built-in or external
parser basing on it's value. In other words we always
entered if-branch for external parser. At this point,
the only way to check if we use default parser is to
compare keyinfo::parser with &ft_default_parser.
storage/myisam/sort.c:
Get rid of MIN_SORT_MEMORY, use MIN_SORT_BUFFER instead
(defined in myisamdef.h, has the same value and purpose).
tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
Improved speed for internal Maria temp tables:
- Don't use packed keys, except with long text fields.
- Don't copy key all accessed pages during key search.
Some new benchmark tests to sql-bench (for group by)
BUILD/compile-pentium64-gcov:
Update script to use same pentium_config flags as other tests
BUILD/compile-pentium64-gprof:
Update script to use same pentium_config flags as other tests
include/my_sys.h:
Added count of my_sync calls
mysql-test/r/variables.result:
tmp_table_size can now be set to 0
sql-bench/test-select.sh:
Added some new test for GROUP BY on a not key field and group by with different order by
sql/mysqld.cc:
Added count of my_sync calls
tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
sql/sql_select.cc:
If tmp_table_size is 0, don't use in memory temp tables (good for benchmarking MyISAM/Maria temp tables)
Don't pack keys for Maria tables; The 8K page size makes packed keys too slow for temp tables.
storage/maria/ma_key_recover.h:
Moved definition to maria_def.h
storage/maria/ma_page.c:
Moved code used to simplify comparing of identical Maria tables to own function (page_cleanup())
Fixed that one can read a page with a read lock.
storage/maria/ma_rkey.c:
For not exact key reads, cache the page where we found key (to speed up future read-next/read-prev calls)
storage/maria/ma_search.c:
Moved code to cache last key page to separate function.
Instead of copying pages, only get a link to the page. This notable speeds up key searches on bigger tables.
storage/maria/ma_write.c:
Added comment
storage/maria/maria_def.h:
Moved page_cleanup() to separate function.
* Implemented a second partial matching strategy via table scan.
This strategy is a fallback when there is no memory for rowid merging.
* Refactored the selection and creation of partial matching strategies,
so that the choice of strategy is encapsulated in a separate method
choose_partial_match_strategy().
* Refactored the representation of partial match strategies so that:
- each strategy is represented by a polymorphic class, and
- the base class for all partial match strategies contains common
execution code.
* Added an estimate of the memory needed for the rowid merge strategy,
and the system variable "rowid_merge_buff_size" to control the maximum
memory to be used by the rowid merge algorithm.
* Added two optimizer_switch system variables to control the choice of
partial match strategy:
"partial_match_rowid_merge", "partial_match_table_scan".
* Fixed multiple problems with deallocation of resources by the partial
match strategies.
sql/mysql_priv.h:
* Added two optimizer_switch system variables to control the choice of
partial match strategy:
"partial_match_rowid_merge", "partial_match_table_scan".
sql/mysqld.cc:
* Added two optimizer_switch system variables to control the choice of
partial match strategy:
"partial_match_rowid_merge", "partial_match_table_scan".
* Added a system variable "rowid_merge_buff_size" to control the maximum
memory to be used by the rowid merge algorithm.
sql/set_var.cc:
* Added a system variable "rowid_merge_buff_size" to control the maximum
memory to be used by the rowid merge algorithm.
sql/sql_class.h:
* Added a system variable "rowid_merge_buff_size" to control the maximum
memory to be used by the rowid merge algorithm.
support-files/build-tags:
Newer versions of BZR require the recursive flag in order to list all files.
This patch fixes some typos and poorly formulated sentences in
the output from mysqld --help --verbose.
Some of the problems described in the bug report are already
handled by the patch for Bug#49447, and are therefore not
included in this patch.
A client doing multiple mysql_library_init() and
mysql_library_end() calls over the lifetime of the process may
experience lost character set data, potentially even a
SIGSEGV.
This patch reinstates the reloading of character set data when
a mysql_library_init() is done after a mysql_library_end().

Fix for Bug#31173: mysqlslap.exe crashes if called without any parameters
.bzrignore:
Fixed .bzrignore rules. Many were simply not ignoring what they were meant to.
client/mysqlslap.c:
Fixed bug for Bug#31173: mysqlslap.exe crashes if called without any parameters
The original patch could cause memory leaks and odd problems depending on how connection was made.
This code ensures that all mysql_options() are set for each mysql_real_connect().
(This patch by Monty)
mysys/my_thr_init.c:
Fixed multiply-initialized critical section on Windows, due to code incorrectly
checking the wrong field in an attempt to prevent multiple-initialization.

Added page fault counters for SHOW PROFILE on Windows.
sql/sql_profile.h:
Added page fault counters for SHOW PROFILE on Windows.
sql/udf_example.def:
Some cleanup functions were not exported from udf_example.dll, causing them to
never be executed, and as a result multiple-initialization of kernel objects
occurred and resources were not being freed correctly.
storage/maria/ma_close.c:
Condition variable share->key_del_cond was never being destroyed, while its
containing heap block was being freed in maria_close(), leaking kernel
resources.
The problem was that the dbug facility was being used after the
per-thread dbug state had already been finalized. The was present
in a few functions which invoked decrement_handler_count, which
in turn invokes my_thread_end on Windows. In my_thread_end, the
per-thread dbug state is finalized. Any use after the state is
finalized ends up creating a new state.
The solution is to process the exit of a function before the
decrement_handler_count function is called.
sql/mysqld.cc:
Process the function exit before decrement_handler_count is
called, as it can end the per-thread dbug state on Windows.
--default-character-set and --character-set-server such
