Mark Adler ee026accde Correct comment in deflate.h. 2012-06-02 10:16:43 -07:00
Mark Adler 4f5779a8e7 Insert the first two strings in the hash table after a flush. 
This allows deflate to generate the same output when continuing after
a Z_SYNC_FLUSH vs. using deflateSetDictionary() after a Z_FULL_FLUSH
or a deflateReset().  It also slightly improves compression when
flushing by providing two more strings to possibly match at the start
of the new block.

Mark Adler 0b828b4aa6 Write out all of the available bits when using Z_BLOCK. 
Previously, the bit buffer would hold 1 to 16 bits after "all" of the
output is provided after a Z_BLOCK deflate() call.  Now at most seven
bits remain in the output buffer after Z_BLOCK.  flush_pending() now
flushes the bit buffer before copying out the byte buffer, in order
for it to really flush as much as possible.

Mark Adler 8f5eceefe8 Remove second empty static block for Z_PARTIAL_FLUSH. 
Z_PARTIAL_FLUSH would sometimes emit two empty static blocks instead
of one in order to provide enough lookahead for inflate to be able
to decode what was last compressed.  inflate no longer needs that
much lookahead, so this removes the possibility of emitting the
second empty static block.  Z_PARTIAL_FLUSH will now emit only one
empty static block.

Mark Adler 263b1a05b0 Allow deflatePrime() to insert bits in the middle of a stream. 
This allows the insertion of multiple empty static blocks for the
purpose of efficiently bringing a stream to a byte boundary.
