Bug 540638 – dev-lang/php after upgrade to dev-db/mysql-5.6.23 - PHP Warning: mysql_connect(): Headers and client library minor version mismatch. Headers:50540 Library:50622 in /path/mysql.inc on line 12

• Product: Gentoo Linux
• Status: RESOLVED CANTFIX

[Description marco 2015-02-19 11:19:46 UTC]

I have a system with dev-lang/php-5.3.29 installed.

After update dev-db/mysql-5.6.22 from dev-db/mysql-5.5.40 the php 5.3 triggers a warning like this:
PHP Warning:  mysql_connect(): Headers and client library minor version mismatch. Headers:50540 Library:50622 in ....

I know that this is a warning but i expected a rebuild for php 5.3 .
why the update did't triggered a rebuild for php 5.3 ?

Can someone explain what trigger a rebuild of the same version of a package A after an update of other package B when package A depend on package B ?




Reproducible: Always

Steps to Reproduce:
1.Install dev-lang/php:53 and dev-db/mysql-5.5.x
2.update dev-db/mysql to dev-db/mysql-5.6-x
3.test mysql_connect() in php 5.3


Expected Results:  
The update of mysql version rebuilds the php-5.3

The reason behind no rebuild being triggered *might* be that virtual/mysql-5.5 was EAPI=4, so no sublots...
Not sure about it though.

I notice the problem on our server with getbinpkg but there is the same problem also on the builder host .

The output ends with the name of the php file and row number that triggered the warning.

PHP Warning:  mysql_connect(): Headers and client library minor version mismatch. Headers:50540 Library:50622 in /path/mysql.inc on line 12

Let me know if you need more info
Thanks

There is nothing that PHP or mysql team can do.

The warning does not hurt any calls to the database.

You can do one of three things:

1) use the mysqlnd driver which does not depend on mysql headers.  USE=mysqlnd on php5.3, or USE=-libmysqlclient on php5.4+ (recommended)
2) Rebuild php 5.3 as is
3) Upgrade to a higher PHP version which will not depend on the headers by default

I highly suggest you plan for upgrading to a newer version than 5.3.
The PHP team will be masking it for security issues ( bug 533998 ) as soon as we can.
