ID: 60849 Updated by: u...@php.net Reported by: haavard dot pedersen at gmail dot com Summary: Too many open links not reported correctly Status: Open -Type: Bug +Type: Feature/Change Request Package: MySQLi related Operating System: Linux PHP Version: 5.3.9 Block user comment: N Private report: N New Comment: This is a bit on the API design/feature request side. mysqli.max_connections is a PHP setting. It is something enforced by the API. Because it does not come from the server side, the server logic does not set an error. There is no error on the line. Thus, the wrapped C API call, mysql_connect_errno() does not return one. Error: 1040 SQLSTATE: 08004 (ER_CON_COUNT_ERROR), Message: Too many connections must not be used to hint that mysqli.max_links has been exceeded. 1040 is a server error code. One needs a client error code, if at all. For example, Error: 2000 (CR_UNKNOWN_ERROR) Message: Unknown MySQL error could be used together with message pointing to the mysqli configuration. I say "if at all" because one also has to ask about the semantics of mysqli_connect_errno(). Previous Comments: ------------------------------------------------------------------------ [2012-01-23 12:25:15] haavard dot pedersen at gmail dot com Description: ------------ The "Too many links" error condition does not provide any error code. The only way you can get a description of the error is via the warning output. Run test script with mysqli.max_connections = 1 to see the problem. This even breaks the documentations example for mysqli_real_connect(). Test script: --------------- $link1 = mysqli_init(); $m_rc1 = mysqli_real_connect($link1, 'localhost', 'dbuser', 'dbpassword', 'testdb', 8889); echo "--- Opening second link ---\n"; $link2 = mysqli_init(); echo "mysqli_init() result : ".var_export($link2, TRUE)."\n"; echo "--- Opening second connection ---\n"; $m_rc2 = mysqli_real_connect($link2, 'localhost', 'dbuser', 'dbpassword', 'testdb', 8889); echo "mysqli_real_connect() result : ".var_export($m_rc2, TRUE)."\n"; echo "Error number: ".var_export(mysqli_connect_errno($link2), TRUE)."\n"; Expected result: ---------------- An error number returned on the last line. Actual result: -------------- Error number is 0, possibly indicating success. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60849&edit=1
