Hi all, and Happy New Year!
I think I just found a couple of bugs in the DeflatePlugin. They were
causing errors in my JsSqueak, I don't fully understand why they don't seem
to cause problems in Squeak. Anyway, after I fixed them, the primitives
work and the PNGReadWriterTest tests are all succeeding for me.
One is in #loadZipEncoderFrom:
The method checks and then determines the writeStreamInstSize and then
fetches the bitBuffer and bitPosition (the first two instvars of
ZipEncoder, a direct subclass of WriteStream) from offsets
writeStreamInstSize + 1 and writeStreamInstSize + 2, although the fetches
The other is in #primitiveZipSendBlock
The method, still working on a ZipEncoder, at the end stores the modified
values for bitBuffer and bitPosition at offset readStreamInstSize + 1 and
readStreamInstSize + 2, which is just wrong.
As I said, I don't quite get why this does not cause at least image-side
errors if not VM crashes in Squeak, but they should probably be fixed
All the best,
