Summary: Uncaught NOT_FOUND_ERR: DOMException 8 loading empty
text file
Product: WebKit
Version: 528+ (Nightly build)
Platform: Macintosh
OS/Version: Mac OS X 10.5
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: New Bugs
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: opendarwin at lapcatsoftware.com
Overview Description:
Loading an empty text file in a WebView raises an uncaught DOM exception. This
occurs both when the .txt file is remote (Content-Length: 0, Content-Type:
text/plain) and when the file is local on disk.
Steps to Reproduce:
1. Launch Terminal.app
2. cd Desktop
3. touch empty.txt
4. Open, build, and run attached sample Xcode project MiniBrowser.
Actual Results:
NSLog() statement at MyDocument.m:248 is not run. Instead, the previous
statement raises an exception.
MiniBrowser[25271:813] *** WebKit discarded an uncaught exception in the
webView:didFinishLoadForFrame: delegate: <DOMException> *** NOT_FOUND_ERR:
DOMException 8
Expected Results:
No exception. The NSLog() statement at MyDocument.m:248 is run.
Build Date & Platform:
git commit 9c5a91f35e3f4e4c7c4882ec9dca03044ddb44ca (trunk at 45288)
Additional Builds and Platforms:
Stock WebKit on Mac OS X 10.5.7 Build 9J61, Safari 4.0.1 (5530.18)
Additional Information:
The sample Xcode project is based on "/Developer/Examples/WebKit/MiniBrowser"
from Xcode 3.1.3. The only changes I made were to set the SDK to 10.5, change
the loaded URL to the text file, and add a few lines of code in
webView:didFinishLoadForFrame:
NSView <WebDocumentView> *documentView = [[frame frameView]
documentView];
if ( [documentView conformsToProtocol:NSProtocolFromString(
@"WebDocumentText" )] )
{
// This raises NOT_FOUND_ERR: DOMException 8
NSString *string = [(<WebDocumentText>)documentView
string];
// We never get here.
NSLog( @"string: %@", string );
}
Here's the gdb backtrace:
