[Lzip-bug] lzlib-0.8-rc1

[Jacob Rief]

Hello Antonio,
doing a compression with member_size=unlimited, but enforcing to
restart a member by the client now works according to the description.
Thanks for implementing this feature :).

Now the question is, how to do it vice versa? Say, you get an
LZIP-stream, but missed the header of the member, or the stream is
corrupt but you want to synchronize the stream up to the next member.
Searching for the special string "LZIP" is easy, although a utility
function implementing the Boyer-Moore-algorithm would by nice (I can
write that, if you want). But then, how to continue? The LZ_Decoder
might be initialized, some data might have been
LZ_decompress_writ'ten, but LZ_decompress_read returns stream errors.
In such a situation the decoder has to be reseted, say
LZ_decompress_clear to flush the written, but not yet read data. The
only way I see is to LZ_decompress_close and to LZ_decompress_open,
deallocating and reallocating the internal buffers, which is not an
elegant solution. Is there some other kind to reset an LZ_Decoder?
