------------------------------------------
Summary: Avoid sticky byte array buffers in Zlib CompressionFilter
Key: DIRMINA-1103
URL: https://issues.apache.org/jira/browse/DIRMINA-1103
Project: MINA
Issue Type: Improvement
Affects Versions: 2.0.21
Reporter: Jörg Michelberger
For each Zlib instance there is a zStream instance which is equipped with new
buffers for each in and out of inflate / deflate. This buffers are not released
after each inflate / deflate. So the last compressed and uncompressed byte[]
and its content for rx and tx is not garbage collectable on each session.
It would be great if there was a reset(zStream) method on Zlib which sets the
in and out to static empty byte[] to release these buffers after usage quite
before returning from Zlib.deflate and Zlib.inflate.
{{reset (zStream) {}}{{ zStream.next_in = EMPTY_BYTE_ARRAY;}}
{{ zStream.next_in_index = 0;}}
{{ zStream.avail_in = 0;}}
{{ zStream.next_out = EMPTY_BYTE_ARRAY;}}
{{ zStream.next_out_index = 0;}}
{{ zStream.avail_out = 0;}}
{{}}}
