    <p>Upon adding the session helper to the app controller Apache begins crashing. I've tracked the problem down a ways with logging and found that in /CORE/cake/libs/controller/component/session the function <code>check()</code> starts running once and doesn't complete. However, the function it calls ,<code>__start()</code>, runs infinitely (at least until Apache crashes it). And by running infinitely I mean the entire <code>__start()</code> function is run multiple times all the way through. Again, this happens once I add the session helper in app controller. Without it Cake seems to run fine until I hit a point where the session helper is used in a view. This system is being upgraded from Cake 1.1 and in Cake 1.1 the session helper was automatically included and ran fine. I've attempted this on both Cake 1.3.7 and Cake 1.3.15 with the same result. I'm guessing something with the session settings conflicts with the way Cake 1.3 does things. Below is my config/core file, the crash information from Apache, and the Apache log just before the crash. If any other information would be helpful please let me know in the comments. Any suggestions how to fix this? Thanks!</p> <p>EDIT: I forgot to include a relevant <a href="https://cakephp.lighthouseapp.com/projects/42648/tickets/1173-cakesession-circular-dependancy-race-condition-or-infinite-loop" rel="nofollow">discussion here</a>. Unfortunately, they don't have a clear solution here, but they appear to want to fix the bug in cake, where I would be happy to alter my code to avoid the bug.</p> <p>EDIT 2: I recently discovered that the manager of this project plans to discontinue the use of database sessions in the future, so that completely fixes the situation for me. Of course I will leave this question up for future visitors though.</p> <p>app/config/core.php:</p> <pre><code>&lt;?php /** * This is core configuration file. * * Use it to configure core behavior of Cake. * * PHP versions 4 and 5 * * CakePHP(tm) : Rapid Development Framework (http://cakephp.org) * Copyright 2005-2010, Cake Software Foundation, Inc.

    2. COWe're hoping to that eventually. But we'd like to get to cake 1.3 first so we can use the well documented transition methods from 1.3 to 2.x. It's actually a fairly large (and old system) so that transition might take a while and if we can get to 1.3 quickly first it would help with many issues we have now because it will allow us to use a newer version of PHP quickly. So upgrading to 2.x is a good choice, but we'd like the quicker route of 1.3 for the time being if possible.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
