Added an extra parameter to all calls to timeout().
1 means we want to set the write timeout
0 means we wnat to set the read timeout
viossl.c:
Add which parameter to ssl timeout routine
vio_priv.h:
Added which parameter to vio_ignore_timeout and vio_ssl_timeout
violite.h:
Add which parameter to vio_timeout sigs
net_serv.cc:
Use proper which code in call to vio_timeout to set the proper timeout
viosocket.c:
Set the appropriate timeout in vio_timeout
it's crucial to disable Nagle algorithm on client for no-reply commands
(like mysql_stmt_free) to always work fast.
Nagle algorithm instructs the sender to buffer (store) data if any
unacknowledged data is outstanding and the size of to-send data is less than
the network segment. It was exactly the case with COM_STMT_CLOSE after
COM_STMT_PREPARE, so the client was waiting for Nagle timer to expire or
for ACK from the server, while the server was holding up ACK because of
delayed acknowledgement algorithm.
The tricky part is that we have been already disabling Nagle
algorithm (by setting TCP_NODELAY)
almost everywhere except Windows (and maybe Netware).
It is the reason why the bug was repeatable only with Windows client.
(continue)
added event_conn_closed
replaced WaitForSingleObject on WaitForMultipleObjects
inserted a check in vio_close()
added SetEvent() for event_conn_closed
Signed auto_increment keys for HASH tables (like for MyISAM tables in 4.0)
nitialize system_charset_info() early. Fixes core dump when starting windows service
Fixed bug in SELECT ... ORDER BY ... LIMIT
Fixed bug in ALTER TABLE and RENAME TABLE with --lower-case-table-names
Fixed hang when using --with-openssl
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
Less logging from replication code (if not started with --log-warnings)
Changed that SHOW INNODB STATUS requre the SUPER privilege
More DBUG statements and a lot of new code comments
(All commit emails since 4.0.1 checked)
This had to be done now, before the 4.1 tree changes to much, to make it easy to propagate bug fixes to the 4.1 tree.
This wrapper noew will include all the necessary, system specific files,
which makes all normal source files much easier to write and maintain.
Portability fixes.
Fixed error number handling bug in mysqltest.
Fixed that error number from insert delayed is reported correctly.
merged new vio code with old violite code.
