Bug 115888 – [BlackBerry] Unable to download blob resource

• Component: WebKit BlackBerry
• Status: RESOLVED FIXED

[Mary Wu]

For blob resource (blob:http....), it's not suitable to go to NetworkStream which don't handle "blob" protocol at all. since blob data already handled in BlobResourceHandle, simply get the data out to download stream.

I'd like to the cast of from const char* to char* inside the platform layer because it knows more about the details.

Leo's issue should be addressed and there are also some style issues.

req is a bad variable name.

There is an implicit conversion operator for String -> BlackBerry::Platform::String.

No problem with me on WebKit side. The blackberry bits were already reviewed internally according to the changelog.

Just a question bellow.

Who owns that memory?

A singleton in our network stack called DownloadManager. (Thanks for making me check that, because I found a bug in it!)

downloadRequested(). Mary please check downloadRequested() which may have leaks on early return branches.
