IPCBlobInputStream is a new type of nsIInputStream that is used only in content process when a Blob is sent from parent to child. This inputStream is for now, just cloneable. When the parent process sends a Blob to a content process, it has the Blob and its inputStream. With its inputStream it creates a IPCBlobInputStreamParent actor. This actor keeps the inputStream alive for following uses (not part of this patch). On the child side we will have, of course, a IPCBlobInputStreamChild actor. This actor is able to create a IPCBlobInputStream when CreateStream() is called. This means that 1 IPCBlobInputStreamChild can manage multiple IPCBlobInputStreams each time one of them is cloned. When the last one of this stream is released, the child actor sends a __delete__ request to the parent side; the parent will be deleted, and the original inputStream, on the parent side, will be released as well. IPCBlobInputStream is a special inputStream because each method, except for Available() fails. Basically, this inputStream cannot be used on the content process for nothing else than knowing the size of the original stream. In the following patches, I'll introduce an async way to use it. |
