++ * 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.
