+ * Getting to provable safe in place decompression is hard.
+ * Worst case behaviours need to be analized.
+ * Background information:
+ *
+ * The file layout is:
+ * magic[2]
+ * method[1]
+ * flags[1]
+ * timestamp[4]
+ * extraflags[1]
+ * os[1]
+ * compressed data blocks[N]
+ * crc[4] orig_len[4]
+ *
+ * resulting in 18 bytes of non compressed data overhead.
+ *
+ * Files divided into blocks
+ * 1 bit (last block flag)
+ * 2 bits (block type)
+ *
+ * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.
+ * The smallest block type encoding is always used.
+ *
+ * stored:
+ * 32 bits length in bytes.
+ *
+ * fixed:
+ * magic fixed tree.
+ * symbols.
+ *
+ * dynamic:
+ * dynamic tree encoding.
+ * symbols.
+ *
+ *
+ * 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.
+ * 10K of actuall data and 4K of bss.

-+ * Getting to provable safe in place decompression is hard.
-+ * Worst case behaviours need to be analized.
-+ * Background information:
-+ *
-+ * The file layout is:
-+ * magic[2]
-+ * method[1]
-+ * flags[1]
-+ * timestamp[4]
-+ * extraflags[1]
-+ * os[1]
-+ * compressed data blocks[N]
-+ * crc[4] orig_len[4]
-+ *
-+ * resulting in 18 bytes of non compressed data overhead.
-+ *
-+ * Files divided into blocks
-+ * 1 bit (last block flag)
-+ * 2 bits (block type)
-+ *
-+ * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.
-+ * The smallest block type encoding is always used.
-+ *
-+ * stored:
-+ * 32 bits length in bytes.
-+ *
-+ * fixed:
-+ * magic fixed tree.
-+ * symbols.
-+ *
-+ * dynamic:
-+ * dynamic tree encoding.
-+ * symbols.
-+ *
-+ *
-+ * 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.
-+ * 10K of actuall data and 4K of bss.
