Added protocol::flush() for easier embedded-server code
Increase block allocation variables a bit as they where a bit too small for MySQL 4.1
Added option --silent to client_test
as this enum is not really usable yet (as MySQL server supports only one
shutdown level), and as SHUTDOWN_DEFAULT is still left to 0, this change
should disturb no user. Later (in 4.1.4 or 4.1.5) code will be pushed to
implement graceful shutdown using this enum.
mysqld >=4.1.3 will however understand shutdown requests sent by clients <4.1.3.
And mysqld <4.1.3 will understand shutdown requests sent by clients >=4.1.3
(it will ignore the level). Those shutdown level are just PLACEHOLDERS now.
So this change is just to make the 4.1 API suitable before it is frozen. Later
we will actually implement the shutdown levels.
Server will however still accept shutdown without specified level; so that old
mysqladmin can still shut server down.
I would like your comments on the names of shutdown level which I chose. You
are welcome to propose better names. Please however check WL#709 before.
Reason for the names I propose is to be accurate, thus leaving possibility
for other levels which we may imagine in the future; that's why I have rejected
names like "fast", "smart", "graceful" so far. My position is that WAIT_ALL_BUFFERS
or WAIT_CRITICAL_BUFFERS say what the shutdown does, whereas for "smart", "fast" you
need to remember what it does.
This should be pushed in 4.1.3 but only after your comments.
after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
connection on the fly, because they first should be written to the binary
log.
To support efficient conversion we need to rewrite prepared statements
binlogging code first.
flag is sent to server with placeholder types.
There were no need to extend the protocol as one additional byte
was reserved for placeholder code, when placeholder code is in range 0-255.
So this byte is now used for flags. Post-review fixes added.
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
BINARY(N) and VARBIBARY(N)
2. More 4.0 compatibility and more BINARY keyword consistency:
2a. CREATE TABLE a (a CHAR(N) BINARY)
is now synonym for
CREATE TABLE a (a CHAR(N) COLLATE xxxx_bin)
2b. SELECT BINARY x
is still synonin for
SELECT x COLLATE xxxxx_bin.
mysql_server_init() now returns error code if something went wrong (Bug #2062)
Don't use my_fopen() when reading symlink information as this may cause problems when a lot of files are opened.
Free thread keys with pthread_key_delete() instead of relying on automatic free. (Bug #2062)
Fixed bug in UNION statement with alias '*'. (Bug #1249)
Fixed a bug in DELETE ... ORDER BY ... LIMIT where the rows where not deleted in the proper order. (Bug #1024).
FOUND_ROWS() could return incorrect number of rows after a query with an impossible WHERE condition.
HOW DATABASES doesn't anymore show .sym files (on windows) that doesn't point to a valid directory. (Bug #1385)
Added option --max-record-length=# to myisamchk
Don't try repair twice if doing myisamchk --repair --force
Shared memory handler didn't clean up things on errors or shutdown
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.
--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.
client capabilities included into libmysqld
some API methods became "virtual"
lots of duplicated code removed
IMHO all the above made library's code way more pleasant to look at, didn't it?
