Subject [jira] [Commented] (CB-1404) EXC_BAD_ACCESS when using XHR_WITH_PAYLOAD bridge mode
Date Tue, 11 Sep 2012 02:56:07 GMT


Tom Clarkson commented on CB-1404:

Easiest is probably if I give you access to the github repo (
- what is your username?

The www folder is generated with jekyll and included in .gitignore - let me know if you would
prefer me to check in the generated files.

>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: iOS
>    Affects Versions: 2.1.0
>         Environment: iPad 2, iOS 5.1.1

>             Fix For: 2.2.0
> When calling a plugin the app crashes on WebThread with EXC_BAD_ACCESS in WebCore::DocumentThreadableLoader::cancel.
> This appears to be some sort of timing issue, as it does not happen on every call - I
am seeing it in an autosave function which makes lots of calls to PGSQLitePlugin. 
> The error did not appear before upgrading to 2.1, and setting the bridge mode to IFRAME_NAV
restores the previous behaviour (no crashes, but odd scrolling functionality).
> Setting the bridge mode to XHR_NO_PAYLOAD also seems to fix it - not sure if removing
the payload actually does anything different or just makes it fast enough that the timing
condition does not come up in normal app usage.
