Hi !
I received no acknowlegment concerning the patch I sent for the asn1
library (sent in August)
So in order to facilitate its treatment I have comitted it on github
otp project clone. Hope you will (re)consider it, or at least, say the
problem with it.

You can get it with :
git fetch git://github.com/titaude30/otp.git asn1_incomplete_packet

To remind you the subject it is a patch which change decode/2
functions generated from a file .asn1 : they return the error {error,
incomplete} when the packet given to decode is incomplete instead of
any error.
It is necessary when implementing functions that decode packet
received from a socket when it's not sure that they are complete (if
messages are too big, they are are splitted).
It 's the completary of another functionality : when .asn1 file are
compiled with the undec_rest option and decode/2 functions are called
with argument packet that contain more of one messages, then decode/2
function return the decoded message plus the rest of the packet.

Best regards,
