KO Observable Cycle Memory Leak

If you're not careful, it's easy to leak memory using knockout.js, especially in single page applications that add and remove objects. Here is one example of a leak created by a reverse dependency.

In this case a child object 'Adder' receives a reference to a 'ViewModel' observable and then uses that reference in its own computed. This creates a reverse dependency that needs to be cleaned up if 'Adder' objects are to be removed.

simplecycle.html is the view. simplecycle.js shows the leaking of Adder objects. simplecycle-fixed.js shows how to fix it.

To see the leak in action, visit http://jsfiddle.net/cygnl7/yRnN3/.

This script will automatically save spreadsheet sheets when edited in Google docs. It also adds a "Backup" menu that allows you to manually backup the currently opened sheet as well as backup all sheets in a spreadsheet.

The backups are put into CSV files, one per sheet, with the filename format being <sheetname>--<timestamp>.csv. They're put into the directory specified in the script. See the installation instructions below for more details.

Installation:

• Open your google spreadsheet
• Open the script editor by clicking on Tools -> Script Editor
• Paste this code into the script editor
• Change the backupFolderName to the folder in which you want backups for this spreadsheet to be saved*
• Select Resources -> Current project's triggers
