|
||||
+ * The buffer for decompression in place is the length of the
|
||||
+ * uncompressed data, plus a small amount extra to keep the algorithm safe.
|
||||
+ * The compressed data is placed at the end of the buffer. The output
|
||||
+ * pointer is placed at the start of the buffer and the input pointer
|
||||
+ * is placed where the compressed data starts. Problems will occur
|
||||
+ * when the output pointer overruns the input pointer.
|
||||
+ *
|
||||
+ * The output pointer can only overrun the input pointer if the input
|
||||
+ * pointer is moving faster than the output pointer. A condition only
|
||||
+ * triggered by data whose compressed form is larger than the uncompressed
|
||||
+ * form.
|
||||
+ *
|
||||
+ * The worst case at the block level is a growth of the compressed data
|
||||
+ * of 5 bytes per 32767 bytes.
|
||||
+ *
|
||||
+ * The worst case internal to a compressed block is very hard to figure.
|
||||
+ * The worst case can at least be boundined by having one bit that represents
|
||||
+ * 32764 bytes and then all of the rest of the bytes representing the very
|
||||
+ * very last byte.
|
||||
+ *
|
||||
+ * All of which is enough to compute an amount of extra data that is required
|
||||
+ * to be safe. To avoid problems at the block level allocating 5 extra bytes
|
||||
+ * per 32767 bytes of data is sufficient. To avoind problems internal to a block
|
||||
+ * adding an extra 32767 bytes (the worst case uncompressed block size) is
|
||||
+ * sufficient, to ensure that in the worst case the decompressed data for
|
||||
+ * block will stop the byte before the compressed data for a block begins.
|
||||
+ * To avoid problems with the compressed data's meta information an extra 18
|
||||
+ * bytes are needed. Leading to the formula:
|
||||
+ *
|
||||
+ * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
|
||||
+ *
|
||||
+ * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
|
||||
+ * Adding 32768 instead of 32767 just makes for round numbers.
|
||||
+ * Adding the decompressor_size is necessary as it musht live after all
|
||||
+ * of the data as well. Last I measured the decompressor is about 14K.
