The default hash bits of zlib is 15 , but can be increased to 16 bits by setting memlevel to 9. ```c deflateInit(strm,level); // set memlevel = 8 deflateInit2(strm, level,...

i think deflate cannot generate such data whose distance is greater than the window size( written in zlib header )

Currently, zlib supports only deflate algorithm.

Roll back this file to a previous version and open it correctly. But oddly, comparing the two versions did not find any changes.

I think you should call deflate with Z_FINSH when you don't have input data.
