New mysqltest that can run mysqltest with PS
Added support for ZEROFILL in PS
Fixed crash when one called mysql_stmt_store_result() without a preceding mysql_stmt_bind_result()
Updated test cases to support --ps-protocol
(Some tests are still run using old protocol)
Fixed crash in PS when using SELECT * FROM t1 NATURAL JOIN t2...
Fixed crash in PS when using sub queries
Create table didn't signal when table was created. This could cause a "DROP TABLE created_table" in another thread to wait "forever"
Fixed wrong permissions check in PS and multi-table updates (one could get permission denied for legal quries)
Fix for PS and SELECT ... PROCEDURE
Reset all warnings when executing a new PS query
group_concat(...ORDER BY) didn't work with PS
Fixed problem with test suite when not using innodb
Simple optimzations and cleanups
Removed compiler warnings and fixed portability issues
Added client functions 'mysql_embedded()' to allow client to check if we are using embedded server
Fixes for purify
statements and negative time/date values".
The bug was in wrong sprintf format used in the client library.
The fix moves TIME -> string conversion functions to sql-common and
utilized them in the client library.
Under strict mode MySQL will generate an error message if there was any conversion when assigning data to a field.
Added checking of date/datetime fields.
If strict mode, give error if we have not given value to field without a default value (for INSERT)
client.c:
Removed call to clear_slave_vio in end_server(). Removed header declaration of clear_slave_vio
slave.cc:
Removed clear_slave_vio function and added calls to thd->clear_active_vio before each call to end_server()
client.c:
Added call to clear_slave_vio inside end_server only when under Windows with repliaction
slave.cc:
Added clear_slave_vio function for clearing active vio on THD under Windows replication
options for mysqlbinlog, with a test file.
This enables user to say "recover my database to how it was this morning at 10:30"
(mysqlbinlog "--stop-datetime=2003-07-29 10:30:00").
Using time functions into client/ made me move them out of sql/ into sql-common/.
+ (small) fix for BUG#4507 "mysqlbinlog --read-from-remote-server sometimes
cannot accept 2 binlogs" (that is, on command line).
#4700 (Unsigned value returned as signed)
just no appropriate checking
#4701 (Errors returned earlier than expected)
all errors returned from send_command()
#4702 (Result isn't freed properly if there's no retrieval)
flush_use_result has only 'client' version and should
be made 'virtual'
work (prepared statements)" and after-review fixes:
- str_to_TIME renamed to str_to_datetime to pair with str_to_time
- functions str_to_time and str_to_TIME moved to sql-common
- send_data_str now supports MYSQL_TYPE_TIME, MYSQL_TIME_DATE,
MYSQL_TIME_DATETIME types of user input buffers.
- few more comments in the client library
- a test case added.
produce hex digits in lower case). (fixed version)
Replaced _dig_vec array with two _dig_vec_upper/_dig_vec_lower arrays.
Added extra argument to int2str function which controls case of digits you get.
Replaced lot of invocations of int2str for decimal radix with more optimized int10_to_str()
function.
Removed unused my_itoa/my_ltoa functions.
Fixed bugs in group_concat with ORDER BY and DISTINCT (Bugs #2695, #3381 and #3319)
Fixed crash when doing rollback in slave and the io thread catched up with the sql thread
Set locked_in_memory properly
flaws list)
TODO:
* verify that no sequence of API calls produces SIGSEGV.
That is, verify that mysql_stmt_init -> mysql_stmt_fetch is OK,
or mysql_stmt_prepare -> mysql_stmt_fetch_column is OK and sets
meaningful error.
* remove alloc_stmt_fields call
* revise stmt->state codes and statement states.
* there are other items in prepared statements 'to fix' document.
Done:
- cleanups and comments
- revision of prepared statement error codes.
- mysql_stmt_prepare is now can always be called (that is, you can reprepare
a statement)
- new implementation of mysql_stmt_close and fetch cancellation
Problem was that we checked for existing connection in stmt_close
and did not free(stmt) if it's closed (that didn't work well with
embedded)
I just added new flag to the stmt_close and now we check it instead
of connection
Cleaned up embedded library access and query cache handling
Changed min stack size to 128K (to allow longer MyISAM keys)
Fixed wrong priority for XOR (should be less than NEG to get -1^1 to work)
now mysql_server_init is called from mysql_init with fake parameters
mysql_once_init code included to mysql_server_init.
embedded-specific initialization is in init_embedded_server function
Fixed compiler warnings (a lot of hidden variables detected by the Forte compiler)
Added a lot of 'version_xxx' strings to 'show variables'
Prevent copying of TMP_TABLE_PARAM (This caused core dump bug on Solaris)
Fixed problem with printing sub selects to debug log
Client option secure-auth deployed on all possible layers:
- mysql client command-line and config file option
- mysql_options option MYSQL_SECURE_AUTH
- mysql_real_connect will automatically take into account that option if
mysql->options.my_cnf_file/my_cnf_group is set
New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
ALTER TABLE table_name ... CHARACTER SET ... now changes all char/varchar/text columns to the given character set
(One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
Removed compiler warnings
Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.
WL#604 Privileges in embedded library
code added to check privileges in embedded library
NO_EMBEDDED_ACCESS_CHECKS macros inserted in code so we can exclude
access-checking parts. Actually we now can exclude these parts from
standalone server as well. Do we need it?
Access checks are disabled in embedded server by default. One should
edit libmysqld/Makefile manually to get this working.
We definitely need the separate configure for embedded server
embedded library
some dirty places cleaned:
uint removed from mysql.h as Miguel suggested
empty_string renamed as my_empty_string to get rid of name's intersections
using embedded library
embedded library
I decided to get rid of #define mysql_some_function in mysql.h
It puzzles users and makes problems with dynamic libraries
Finally, there are only two functions left, that are covered with
the #define-s and it won't hurt performance at all
Prepared statements in embedded server
Several changes in library code with two goals:
to make mysql_prepare_stmt working in embedded server
to get rid of #define mysql_interface_func mysql->methods->interface_func
in user's interface
--old-passwords
Support for option --old-protocol was removed.
Some test performed.
Tests for SSL and replication are pending.
More strict following to specification for --old-passwords
is in the TODO.
For now following tasks have been done:
- PASSWORD() function was rewritten. PASSWORD() now returns SHA1
hash_stage2; for new passwords user.password contains '*'hash_stage2; sql_yacc.yy also fixed;
- password.c: new functions were implemented, old rolled back to 4.0 state
- server code was rewritten to use new authorization algorithm (check_user(), change
user, and other stuff in sql/sql_parse.cc)
- client code was rewritten to use new authorization algorithm
(mysql_real_connect, myslq_authenticate in sql-common/client.c)
- now server barks on 45-byte-length 4.1.0 passwords and refuses 4.1.0-style
authentification. Users with 4.1.0 passwords are blocked (sql/sql_acl.cc)
- mysqladmin.c was fixed to work correctly with new passwords
Tests for 4.0-4.1.1, 4.1.1-4.1.1 (with or without db/password) logons was performed;
mysqladmin also was tested. Additional check are nevertheless necessary.
