[Pharo-project] SocketStream>>#next:

by Sven Van Caekenberghe

Hi, Related to a hard to find Zinc bug that I just discovered, I require some feedback as to the semantics of SocketStream>>#next: IMHO, the current implementation is semantically wrong. I would expect the semantics to be: try to read count elements and return a new species collection containing them. If less elements are available, return a smaller collection. ( It then becomes effectively a limited #upToEnd). I always implemented #next: by delegating to #next:into:, to #next:into:startingAt: and finally #readInto:startingAt:count: (see for example ZdcAbstractSocketStream, ZnLimitedReadStream or ZnChunkedReadStream). When you look at the implementations of #next:into:, #next:into:startingAt: and #readInto:startingAt:count: on SocketStream, the fact that ConnectionClosed is not signalled is clearly stated. Yet SocketStream>>#next: is different, it does signal ConnectionClosed, which makes it impossible (unless you proceed the exception) to read up to end. And this is what InflateStream>>#getFirstBuffer expects. And which fails when less than 65536 bytes are available. Note that InflateStream reads its subsequent buffers using #next:into:startingAt: (see #moveSourceToFront) so that it properly reads up to end without signalling ConnectionClosed for larger payloads. I can easily program around it, but I think SocketStream>>#next: is wrong and should be changed. Any opinions ? Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

I think I finally found the cause of this mysterious bug. The bug only appears when ZnEntityReader>>#readEntityFromStream needs to read a GZIP compressed response without an explicit Content-Length (so that it has to read up to end - pretty rare, apparently more common in the case of certain proxies) for a total size less than 65536 bytes (that is why it didn't happen on all cases ;-). In these particular circumstances, a GZipReadStream was created directly on top of a raw SocketStream, which immediately sends a #next: 65536 to the SocketStream. Which fails with a ConnectionClosed instead of returning just the available bytes (like #upToEnd). The fix depends on the question which method is actually wrong, the subject of my next mail ;-) Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill
