Socket timeouts in client library were used only on Windows.
The solution is to use socket timeouts in client library on all
systems were they are supported.
No test case is provided because it is impossible to simulate network
failure in current test suit.
Add define YASSL_PREFIX when compiling yassl
Import patch from yaSSL
- avoid allocating memory for each call to 'EVP_md5' and
'EVP_des_ede3_cbc' which were not released until server was stopped
- Those functions are used from the SQL function 'des_encrypt' and
'des_decrypt'.
Add new define YASSL_PREFIX beforee including ssl.h to activate inclusion of prefix_*.h files
Bug#20022 mysql-test-run can't be run with secure connections turned on for all testcases
- Part 1, fixes rpl- and federated-tests where connection is made to 127.0.0.1
- Include prefix files that renames all public functions in yaSSLs
OpenSSL API to ya<function_name>. They will otherwise conflict
with OpenSSL functions if loaded by an application that uses OpenSSL
as well as libmysqlclient with yaSSL support.
Bug#18235: assertion/crash when windows mysqld is ended with ctrl-c
Two threads both try a shutdown sequence which creates a race to the
de-init/free of certain resources.
This exists in similar form in the client as 17926: "mysql.exe crashes
when ctrl-c is pressed in windows."
Update after merge to 5.0
BUG#18669: Session COM_STATISTICS breaks mysqladmin status.
Changed COM_STATISTICS to display the global status, instead of thead status, for slow queries and table opens.
- In function 'handle_grant_struct' when searching the memory structures for an
entry to modify, convert all entries here host.hostname is NULL to "" and compare that
with the host passed in argument "user_from".
- A user created with hostname "" is stored in "mysql.user" table as host="" but when loaded into
memory it'll be stored as host.hostname NULL. Specifiying "" as hostname means
that "any host" can connect. Thus is's correct to turn on allow_all_hosts
when such a user is found.
- Review and fix other places where host.hostname may be NULL.
BUG#19394 OPT_INNODB_THREAD_CONCURRENCY duplicated
Removed duplication (not a user-visible change)
- Include prefix files that renames all public functions in yaSSLs
OpenSSL API to ya<function_name>. They will otherwise conflict
with OpenSSL functions if loaded by an application that uses OpenSSL
as well as libmysqlclient with yaSSL support.
Added support for key_block_size to MyISAM.
Simplify interface to 'new Key' to make it easier to add new key options.
mysqld option --new is used to define where key options are printed.
(In 5.3 we should move all key options to after key part definition to avoid problem with reserved names)
Fixed some compiler warnings and a memory leak in ssl
- Add new function 'ssl_verify_server_cert' which is used if we are
connecting to the server with SSL. It will compare the hostname in
the server's cert against the hostname that we used when connecting
to the server. Will reject the connection if hostname does not match.
- Add new option "OPT_SSL_VERIFY_SERVER_CERT" to be passed to mysql_options
which will turn on checking of servers cert.
- Add new argument "ssl-verify-server-cert" to all mysql* clients which
will activate the above option.
- Generate a new server cert with 1024 bits that has "localhost" as the server name.
- Use yassl_includes and yassl_libs instead of openssl_includes and openssl_libs
to avoid that mysql_config returns that libyassl and libtaocrypt are needed for linking.
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
The patch implements the idea suggested by Olaf van der Spek in
thread "Client: many small reads?" (internals@lists.mysql.com).
Now small reads performed by the client library are buffered.
The buffering gives up to 2 times speedup when retrieving
one-column tables.
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.
Add support for VARCHAR with 1 or 2 length bytes
Enable VARCHAR packing in MyISAM files (previous patch didn't pack data properly)
Give error if we got problems in temporary tables during a SELECT
Don't use new table generated by ALTER TABLE if index generation fails
Fixed wrong call by range_end() (Could cause an ASSERT in debug mode)
(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
