27 * Getting to provable safe in place decompression is hard.
28 * Worst case behaviours need to be analized.
29 * Background information:
30 *
31 * The file layout is:
32 * magic[2]
33 * method[1]
34 * flags[1]
35 * timestamp[4]
36 * extraflags[1]
37 * os[1]
38 * compressed data blocks[N]
39 * crc[4] orig_len[4]
40 *
41 * resulting in 18 bytes of non compressed data overhead.
42 *
43 * Files divided into blocks
44 * 1 bit (last block flag)
45 * 2 bits (block type)
46 *
47 * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.
48 * The smallest block type encoding is always used.
49 *
50 * stored:
51 * 32 bits length in bytes.
52 *
53 * fixed:
54 * magic fixed tree.
55 * symbols.
56 *
57 * dynamic:
58 * dynamic tree encoding.
59 * symbols.
60 *
61 *
62 * The buffer for decompression in place is the length of the
63 * uncompressed data, plus a small amount extra to keep the algorithm safe.
64 * The compressed data is placed at the end of the buffer. The output
65 * pointer is placed at the start of the buffer and the input pointer
66 * is placed where the compressed data starts. Problems will occur
67 * when the output pointer overruns the input pointer.
68 *
69 * The output pointer can only overrun the input pointer if the input
70 * pointer is moving faster than the output pointer. A condition only
71 * triggered by data whose compressed form is larger than the uncompressed
72 * form.
73 *
74 * The worst case at the block level is a growth of the compressed data
75 * of 5 bytes per 32767 bytes.
76 *
77 * The worst case internal to a compressed block is very hard to figure.
78 * The worst case can at least be boundined by having one bit that represents
79 * 32764 bytes and then all of the rest of the bytes representing the very
80 * very last byte.
81 *
82 * All of which is enough to compute an amount of extra data that is required
83 * to be safe. To avoid problems at the block level allocating 5 extra bytes
84 * per 32767 bytes of data is sufficient. To avoind problems internal to a block
85 * adding an extra 32767 bytes (the worst case uncompressed block size) is
86 * sufficient, to ensure that in the worst case the decompressed data for
87 * block will stop the byte before the compressed data for a block begins.
88 * To avoid problems with the compressed data's meta information an extra 18
89 * bytes are needed. Leading to the formula:
90 *
91 * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
92 *
93 * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
94 * Adding 32768 instead of 32767 just makes for round numbers.
95 * Adding the decompressor_size is necessary as it musht live after all
96 * of the data as well. Last I measured the decompressor is about 14K.
97 * 10K of actuall data and 4K of bss.
