create bookmark with long string ( 10MB) causing WebProcess crashed

During a test, the following code caused WebProcess crashed when the folder name string size is 10MB. 

var folder = new tizen.BookmarkFolder(folder_param);

If I make the string size smaller, e.g. 1MB, the code ran correctly.

Which gerrit project under this page https://tz.otcshare.org/gerrit/#/admin/projects/ has the source code for Tizen Bookmark API so I can download it and look at the code?

My test was done on Josephone mobile device and the image file is  josephine tizen-2.1-mobile_20130826.1.

Any tip will be greatly appreciated.

 

Thanks,

Chi

Hello, which SDK version you have used for the testing? I just now have successfully created the bookmark folder with folder name string = 100KB. I have used a SDK 2.2

Sorry that I made a typo in my original post. I meant to say folder name string of size 10MB. My original post has been fixed now.

The SDK I'm using is 2.2.0 FYI.

Can you share your sample project? By the way I can't imagine in which case you will really need to create folder with 100MB folder name.

Here is the link of the widget file https://skydrive.live.com/redir?resid=80E43988863471F6!616&authkey=!AIhebz2DRHEjYpU There is a bug in the JavaScript code in the widget file : when creating the folder name iterating through an array, the code goes beyond the array boundary by accessing buffer[l] where l is the length of the buffer. After I fixed the bug, then reran the test with 1MB buffer size, the code ran succesfully. However with 10MB buffer size/folder name string, the code was able to concatenate/create a string of 10MB size but failed to create the folder at the line of code var folder = new tizen.BookmarkFolder(folder_param); So there seems to be two questions to answer : 1) how is the Tizen engine supposed to behave/handle accessing out-of-boundary array element? 2) Seemly buffer over flow issue in the Tizen Bookmark API. My test was done on josephine tizen-2.1-mobile_20130826.1 image Thanks!
