Bug #56144	Workbench Administration, Connections tab, list always scrolling itself

Category:	MySQL Workbench: Administration	Severity:	S3 (Non-critical)
Version:	5.2.26 CE	OS:	Windows (Windows 7 64bit)
Assigned to:	Mike Lischke	CPU Architecture:	Any

Description:
Connecting to a very active database server running MySQL 5.1.33 on CentOS4 with close to 3000 connections, MySQL Workbench 5.2.26 CE running on Windows 7 Enterprise 64bit.

This is a continuous process and am unable to find any mention of this in the bug list or how to fix this. At first I thought it was a performance problem and found references to making changes to the "Undo History Size" setting but this has no effect.

I go back to using the MySQL Administrator application which works fine (and behaves more responsive, incidentally).

How to repeat:
Steps to reproduce:
1. Open up MySQL Workbench
2. Select the appropriate host under Server Administration
3. Note the settings of the Server Status, particularly the Connection Usage which in this case is sitting at just under 2800 connections
4. Watch the scroll handle on the right side of list grow then shrink back down
5. Scroll half-way down the list, after about a second, point 4 reoccurs and the list position is reset to the beginning
6. While it rescrolls, application freezes for a second
7. Forced to go back to using MySQL Administrator application to view connections

Suggested fix:
Possible problem with "auto-refresh"?

I missed a step between points 3 and 4 in the "How to reproduce" section, which should state:

3.5. Click on the Connections /Edit Connection List/ tab

Thank you for the report.

Verified as described.

This can be a feature though, because if you select a connection it scrolls down in such a way so selected connection is last in the list.

So will it be considered a bug? Because until it stops behaving as it does currently, it's completely unusable.

Fixed in repository.

fix confirmed in repository

An entry has been added to the 5.2.31 changelog:

In the Connections tab of the Administrator, scrolling did not work correctly when there were large numbers of connections.
