Major changes to _restore_connection_defaults
- added code block to finds and releases the active mysql result (if any)
- this should prevent the 'Commands out of sync' error that would be
raised when a query is made when unfreed results exist
Minor changes to _restore_connection_defaults
- replaced calls to mysql_real_query with mysql_query
- we probably should not be using mysql_real_query without checking to
see if we have a version that supports the function.
- given that we control the query strings here and do not need to
worry about binary safety, I am using mysql_query instead
- see the bug report for further discussion
#- This will remove the annoying notices, while this function is used in
# a lot of scripts. There is not reason why we should discontinue it's use
# as it works perfect for about 99% of the time.
Why:
1) Its not the common way to add additionally functionality for functions or
features which are already implemented in SQL. Therefore also a lot of
mysql functions are marked as deprecated (and will be removed in near future)
2) The implemented workaround works only when mysql_select_db was called
before (fetching the databasename from mysql->conn.db). It returns invalid
or inconsistent results e.g.:
- when "USE databasename" via mysql_query was used
- when database was dropped or grant privileges had changed.
In conjunction with persistent connection, there are also some inconsistencies,
cause mysql_select_db returns the databasename from an old connection.
To determine the database name just use the SQL command "SELECT DATABASE()"
MYSQL_CLIENT_SSL for ssl connections
MYSQL_CLIENT_COMPRESS for compressed protocol
MYSQL_CLIENT_IGNORE_SPACES for spaces after function names
MYSQL_CLIENT_INTERACTIVE for closing connections after timeout_interactive seconds
2) Optional parameter client_flags for mysql_connect and mysql_pconnect
For parameter desctiption see 1.
This also should fix bug #13589
3) New internal function _rollback_mysql_transactions, which is called via
PHP_RSHUTDOWN_FUNCTION
This fixes bug #12513
b) changed mysql_list_processes, mysql_stat (zend_parse_parameters)
c) New functions:
1) mysql_real_escape_string this function is similar to mysql_escape_string (deprecated).
it needs a mysql-connection to escape a string according to the
current character set
2) mysql_character_set_name returns the current character set for the connection
3) mysql_thread_id return the pid for the current connection. This function is usefull
when using mysql_list_processes
information on the processes running in the
MySQL server.
(PHP mysql_stat) Returns a string containing information on the status
of the MySQL server.
@- Added two new functions: mysql_list_processes and mysql_stat (Georg)
@- mysql_list_processes() fetches information on the processes running on
@ the MySQL server.
@- mysql_stat() returns status information for a MySQL server.
# Committed for Georg by Zak
- Some tests were only run when compiling with the bundled libs.
(caused some compile warnings with external mysql libs)
- Another try to fix the zlib issue..(uncompress)
