This is actually undesireable as it takes away control from the user who
may want to pause/resume to throttle the upload stream, or synchronize
it with disk flushing.
I actually ran into memory issues when trying to stream huge files to
disc as the file module was building up a huge action buffer. This can
now easily be avoided like this:
part.addListener('body', function(chunk) {
req.pause();
file.write(chunk).addCallback(function() {
req.resume();
});
}
Multipart parts now have a name and filename property. Those are the
same as:
part.headers['content-disposition'].name
part.headers['content-disposition'].filename
This patch also updates and improves the docs for the multipart module.
