Subject [jira] [Commented] (CB-1404) EXC_BAD_ACCESS when using XHR_WITH_PAYLOAD bridge mode
Date Tue, 11 Sep 2012 02:28:07 GMT

    [ https://issues.apache.org/jira/browse/CB-1404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13452653#comment-13452653

Andrew Grieve commented on CB-1404:
-----------------------------------

Thanks Tom, that's very useful info! Would you be able to attach a zip of your project that
can repro the error? Or send it to me directly if you want to keep it out of the public eye?
If not, that's fine too and I'll try testing this out in a more involved app. It does sounds
like it might be memory related. Possibly XHR_WITH_PAYLOAD is leaking in some way.

> 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.
