Lengths 11..257 are represented as a symbol and - * some number of extra bits that are added as an integer to the base length - * of the length symbol. The number of extra bits is determined by the base - * length symbol. These are in the static arrays below, lens[] for the base - * lengths and lext[] for the corresponding number of extra bits. - * - * - The reason that 258 gets its own symbol is that the longest length is used - * often in highly redundant files. Note that 258 can also be coded as the - * base value 227 plus the maximum extra value of 31. While a good deflate - * should never do this, it is not an error, and should be decoded properly. - * - * - If a length is decoded, including its extra bits if any, then it is - * followed a distance code. There are up to 30 distance symbols. Again - * there are many more possible distances (1..32768), so extra bits are added - * to a base value represented by the symbol.

The base distances and - * corresponding number of extra bits are below in the static arrays dist[] - * and dext[]. - * - * - Literal bytes are simply written to the output. A length/distance pair is - * an instruction to copy previously uncompressed bytes to the output. The - * copy is from distance bytes back in the output stream, copying for length - * bytes. - * - * - Distances pointing before the beginning of the output data are not - * permitted. - * - * - Overlapped copies, where the length is greater than the distance, are - * allowed and common. For example, a distance of one and a length of 258 - * simply copies the last byte 258 times. A distance of four and a length of - * twelve copies the last four bytes three times.

New dynamic blocks allow the compressor to - * rapidly adapt to changing data with new codes optimized for that data. - * - * - The codes used by the deflate format are "canonical", which means that - * the actual bits of the codes are generated in an unambiguous way simply - * from the number of bits in each code. Therefore the code descriptions - * are simply a list of code lengths for each symbol. - * - * - The code lengths are stored in order for the symbols, so lengths are - * provided for each of the literal/length symbols, and for each of the - * distance symbols. - * - * - If a symbol is not used in the block, this is represented by a zero as - * as the code length. This does not mean a zero-length code, but rather - * that no code should be created for this symbol. There is no way in the - * deflate format to represent a zero-length code. - * - * - The maximum number of bits in a code is 15, so the possible lengths for - * any code are 1..15. - * - * - The fact that a length of zero is not permitted for a code has an - * interesting consequence. Normally if only one symbol is used for a given - * code, then in fact that code could be represented with zero bits. However - * in deflate, that code has to be at least one bit. So for example, if - * only a single distance base symbol appears in a block, then it will be - * represented by a single code of length one, in particular one 0 bit. This - * is an incomplete code, since if a 1 bit is received, it has no meaning, - * and should result in an error. So incomplete distance codes of one symbol - * should be permitted, and the receipt of invalid codes should be handled. - * - * - It is also possible to have a single literal/length code, but that code - * must be the end-of-block code, since every dynamic block has one. This - * is not the most efficient way to create an empty block (an empty fixed - * block is fewer bits), but it is allowed by the format. So incomplete - * literal/length codes of one symbol should also be permitted. - * - * - If there are only literal codes and no lengths, then there are no distance - * codes. This is represented by one distance code with zero bits. - * - * - The list of up to 286 length/literal lengths and up to 30 distance lengths - * are themselves compressed using Huffman codes and run-length encoding. In - * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means - * that length, and the symbols 16, 17, and 18 are run-length instructions. - * Each of 16, 17, and 18 are follwed by extra bits to define the length of - * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10 - * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols - * are common, hence the special coding for zero lengths. - * - * - The symbols for 0..18 are Huffman coded, and so that code must be - * described first. This is simply a sequence of up to 19 three-bit values - * representing no code (0) or the code length for that symbol (1..7). - * - * - A dynamic block starts with three fixed-size counts from which is computed - * the number of literal/length code lengths, the number of distance code - * lengths, and the number of code length code lengths (ok, you come up with - * a better name!) in the code descriptions. For the literal/length and - * distance codes, lengths after those provided are considered zero, i.e. no - * code. The code length code lengths are received in a permuted order (see - * the order[] array below) to make a short code length code length list more - * likely. As it turns out, very short and very long codes are less likely - * to be seen in a dynamic code description, hence what may appear initially - * to be a peculiar ordering. - * - * - Given the number of literal/length code lengths (nlen) and distance code - * lengths (ndist), then they are treated as one long list of nlen + ndist - * code lengths. Therefore run-length coding can and often does cross the - * boundary between the two sets of lengths. - * - * - So to summarize, the code description at the start of a dynamic block is - * three counts for the number of code lengths for the literal/length codes, - * the distance codes, and the code length codes. This is followed by the - * code length code lengths, three bits each. This is used to construct the - * code length code which is used to read the remainder of the lengths. Then - * the literal/length code lengths and distance lengths are read as a single - * set of lengths using the code length codes. Codes are constructed from - * the resulting two sets of lengths, and then finally you can start - * decoding actual compressed data in the block. - * - * - For reference, a "typical" size for the code description in a dynamic - * block is around 80 bytes. - */ -local int dynamic(struct state *s) -{ - int nlen, ndist, ncode; /* number of lengths in descriptor */ - int index; /* index of lengths[] */ - int err; /* construct() return value */ - short lengths[MAXCODES]; /* descriptor code lengths */ - short lencnt[MAXBITS+1], lensym[MAXLCODES]; /* lencode memory */ - short distcnt[MAXBITS+1], distsym[MAXDCODES]; /* distcode memory */ - struct huffman lencode = {lencnt, lensym}; /* length code */ - struct huffman distcode = {distcnt, distsym}; /* distance code */ - static const short order[19] = /* permutation of code length codes */ - {16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15}; - - /* get number of lengths in each table, check lengths */ - nlen = bits(s, 5) + 257; - ndist = bits(s, 5) + 1; - ncode = bits(s, 4) + 4; - if (nlen > MAXLCODES || ndist > MAXDCODES) - return -3; /* bad counts */ - - /* read code length code lengths (really), missing lengths are zero */ - for (index = 0; index < ncode; index++) - lengths[order[index]] = bits(s, 3); - for (; index < 19; index++) - lengths[order[index]] = 0; - - /* build huffman table for code lengths codes (use lencode temporarily) */ - err = construct(&lencode, lengths, 19); - if (err != 0) return -4; /* require complete code set here */ - - /* read length/literal and distance code length tables */ - index = 0; - while (index < nlen + ndist) { - int symbol; /* decoded value */ - int len; /* last length to repeat */ - - symbol = decode(s, &lencode); - if (symbol < 16) /* length in 0..15 */ - lengths[index++] = symbol; - else { /* repeat instruction */ - len = 0; /* assume repeating zeros */ - if (symbol == 16) { /* repeat last length 3..6 times */ - if (index == 0) return -5; /* no last length! */ - len = lengths[index - 1]; /* last length */ - symbol = 3 + bits(s, 2); - } - else if (symbol == 17) /* repeat zero 3..10 times */ - symbol = 3 + bits(s, 3); - else /* == 18, repeat zero 11..138 times */ - symbol = 11 + bits(s, 7); - if (index + symbol > nlen + ndist) - return -6; /* too many lengths! */ - while (symbol--) /* repeat last or zero symbol times */ - lengths[index++] = len; - } - } - - /* build huffman table for literal/length codes */ - err = construct(&lencode, lengths, nlen); - if (err < 0 || (err > 0 && nlen - lencode.count[0] != 1)) - return -7; /* only allow incomplete codes if just one code */ - - /* build huffman table for distance codes */ - err = construct(&distcode, lengths + nlen, ndist); - if (err < 0 || (err > 0 && ndist - distcode.count[0] != 1)) - return -8; /* only allow incomplete codes if just one code */ - - /* decode data until end-of-block code */ - return codes(s, &lencode, &distcode); -} - -/* - * Inflate source to dest.

* - * The "deflation" process depends on being able to identify portions - * of the input text which are identical to earlier input (within a - * sliding window trailing behind the input currently being processed). - * - * The most straightforward technique turns out to be the fastest for - * most input files: try all possible matches and select the longest. - * The key feature of this algorithm is that insertions into the string - * dictionary are very simple and thus fast, and deletions are avoided - * completely. Insertions are performed at each input character, whereas - * string matches are performed only when the previous match ends. So it - * is preferable to spend more time in matches to allow very fast string - * insertions and avoid deletions. The matching algorithm for small - * strings is inspired from that of Rabin & Karp. A brute force approach - * is used to find longer strings when a small match has been found. - * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze - * (by Leonid Broukhis). - * A previous version of this file used a more sophisticated algorithm - * (by Fiala and Greene) which is guaranteed to run in linear amortized - * time, but has a larger average cost, uses more memory and is patented. - * However the F&G algorithm may be faster for some highly redundant - * files if the parameter max_chain_length (described below) is too large. - * - * ACKNOWLEDGEMENTS - * - * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and - * I found it in 'freeze' written by Leonid Broukhis. - * Thanks to many people for bug reports and testing. - * - * REFERENCES - * - * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". - * Available in http://www.ietf.org/rfc/rfc1951.txt - * - * A description of the Rabin and Karp algorithm is given in the book - * "Algorithms" by R.

The first pass generates - enough deflate blocks to produce output to fill the requested - output size plus a specfied excess amount (see the EXCESS define - below). The last deflate block may go quite a bit past that, but - is discarded. The second pass decompresses and recompresses just - the compressed data that fit in the requested plus excess sized - buffer. The deflate process is terminated after that amount of - input, which is less than the amount consumed on the first pass. - The last deflate block of the result will be of a comparable size - to the final product, so that the header for that deflate block and - the compression ratio for that block will be about the same as in - the final product. The third compression pass decompresses the - result of the second step, but only the compressed data up to the - requested size minus an amount to allow the compressed stream to - complete (see the MARGIN define below). That will result in a - final compressed stream whose length is less than or equal to the - requested size. Assuming sufficient input and a requested size - greater than a few hundred bytes, the shortfall will typically be - less than ten bytes. - - If the input is short enough that the first compression completes - before filling the requested output size, then that compressed - stream is return with no recompression. - - EXCESS is chosen to be just greater than the shortfall seen in a - two pass approach similar to the above. That shortfall is due to - the last deflate block compressing more efficiently with a smaller - header on the second pass. EXCESS is set to be large enough so - that there is enough uncompressed data for the second pass to fill - out the requested size, and small enough so that the final deflate - block of the second pass will be close in size to the final deflate - block of the third and final pass.

The gzip file is written to directly, to - avoid copying that file, in case it's large. Note that this results in the - unfriendly behavior that if gzappend fails, the gzip file is corrupted. - - This program was written to illustrate the use of the new Z_BLOCK option of - zlib 1.2.x's inflate() function. This option returns from inflate() at each - block boundary to facilitate locating and modifying the last block bit at - the start of the final deflate block. Also whether using Z_BLOCK or not, - another required feature of zlib 1.2.x is that inflate() now provides the - number of unusued bits in the last input byte used. gzappend will not work - with versions of zlib earlier than 1.2.1. - - gzappend first decompresses the gzip file internally, discarding all but - the last 32K of uncompressed data, and noting the location of the last block - bit and the number of unused bits in the last byte of the compressed data. - The gzip trailer containing the CRC-32 and length of the uncompressed data - is verified. This trailer will be later overwritten. - - Then the last block bit is cleared by seeking back in the file and rewriting - the byte that contains it. Seeking forward, the last byte of the compressed - data is saved along with the number of unused bits to initialize deflate. - - A deflate process is initialized, using the last 32K of the uncompressed - data from the gzip file to initialize the dictionary. If the total - uncompressed data was less than 32K, then all of it is used to initialize - the dictionary. The deflate output bit buffer is also initialized with the - last bits from the original deflate stream. From here on, the data to - append is simply compressed using deflate, and written to the gzip file. - When that is complete, the new CRC-32 and uncompressed length are written - as the trailer of the gzip file. - */ - -#include -#include -#include -#include -#include -#include "zlib.h" - -#define local static -#define LGCHUNK 14 -#define CHUNK (1U << LGCHUNK) -#define DSIZE 32768U - -/* print an error message and terminate with extreme prejudice */ -local void bye(char *msg1, char *msg2) -{ - fprintf(stderr, "gzappend error: %s%s\n", msg1, msg2);

The compressed file is left open, and can then - be read randomly, having to decompress on the average SPAN/2 uncompressed - bytes before getting to the desired block of data. - - An access point can be created at the start of any deflate block, by saving - the starting file offset and bit of that block, and the 32K bytes of - uncompressed data that precede that block. Also the uncompressed offset of - that block is saved to provide a referece for locating a desired starting - point in the uncompressed stream. build_index() works by decompressing the - input zlib or gzip stream a block at a time, and at the end of each block - deciding if enough uncompressed data has gone by to justify the creation of - a new access point.

Then the decompression continues to read the desired uncompressed - data from the file. - - Another approach would be to generate the index on demand. In that case, - requests for random access reads from the compressed data would try to use - the index, but if a read far enough past the end of the index is required, - then further index entries would be generated and added. - - There is some fair bit of overhead to starting inflation for the random - access, mainly copying the 32K byte dictionary. So if small pieces of the - file are being accessed, it would make sense to implement a cache to hold - some lookahead and avoid many calls to extract() for small lengths. - - Another way to build an index would be to use inflateCopy(). That would - not be constrained to have access points at block boundaries, but requires - more memory per access point, and also cannot be saved to file due to the - use of pointers in the state.

The state machine is - structured roughly as follows: - - for (;;) switch (state) { - ... - case STATEn: - if (not enough input data or output space to make progress) - return; - ... make progress ... - state = STATEm; - break; - ... - } - - so when inflate() is called again, the same case is attempted again, and - if the appropriate resources are provided, the machine proceeds to the - next state. The NEEDBITS() macro is usually the way the state evaluates - whether it can proceed or should return. NEEDBITS() does the return if - the requested bits are not available. The typical use of the BITS macros - is: - - NEEDBITS(n); - ... do something with BITS(n) ... - DROPBITS(n); - - where NEEDBITS(n) either returns from inflate() if there isn't enough - input left to load n bits into the accumulator, or it continues. BITS(n) - gives the low n bits in the accumulator. When done, DROPBITS(n) drops - the low n bits off the accumulator. INITBITS() clears the accumulator - and sets the number of available bits to zero. BYTEBITS() discards just - enough bits to put the accumulator on a byte boundary. After BYTEBITS() - and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. - - NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return - if there is no input available. The decoding of variable length codes uses - PULLBYTE() directly in order to pull just enough bytes to decode the next - code, and no more. - - Some states loop until they get enough input, making sure that enough - state information is maintained to continue the loop where it left off - if NEEDBITS() returns in the loop. For example, want, need, and keep - would all have to actually be part of the saved state in case NEEDBITS() - returns: - - case STATEw: - while (want < need) { - NEEDBITS(n); - keep[want++] = BITS(n); - DROPBITS(n); - } - state = STATEx; - case STATEx: - - As shown above, if the next state is also the next case, then the break - is omitted. - - A state may also return if there is not enough output space available to - complete that state. Those states are copying stored data, writing a - literal byte, and copying a matching string. - - When returning, a "goto inf_leave" is used to update the total counters, - update the check value, and determine whether any progress has been made - during that inflate() call in order to return the proper return code. - Progress is defined as a change in either strm->avail_in or strm->avail_out. - When there is a window, goto inf_leave will update the window with the last - output written. If a goto inf_leave occurs in the middle of decompression - and there is no window currently, goto inf_leave will create one and copy - output to the window for the next call of inflate(). - - In this implementation, the flush parameter of inflate() only affects the - return code (per zlib.h). inflate() always writes as much as possible to - strm->next_out, given the space available and the provided input--the effect - documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers - the allocation of and copying into a sliding window until necessary, which - provides the effect documented in zlib.h for Z_FINISH when the entire input - stream available. So the only thing the flush parameter actually does is: - when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it - will return Z_BUF_ERROR if it has not reached the end of the stream. - */ - -int ZEXPORT inflate(strm, flush) -z_streamp strm; -int flush; -{ - struct inflate_state FAR *state; - unsigned char FAR *next; /* next input */ - unsigned char FAR *put; /* next output */ - unsigned have, left; /* available input and output */ - unsigned long hold; /* bit buffer */ - unsigned bits; /* bits in bit buffer */ - unsigned in, out; /* save starting available input and output */ - unsigned copy; /* number of stored or match bytes to copy */ - unsigned char FAR *from; /* where to copy match bytes from */ - code this; /* current decoding table entry */ - code last; /* parent table entry */ - unsigned len; /* length to copy for repeats, bits to drop */ - int ret; /* return code */ -#ifdef GUNZIP - unsigned char hbuf[4]; /* buffer for gzip header crc calculation */ -#endif - static const unsigned short order[19] = /* permutation of code lengths */ - {16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15}; - -#if defined(__NetBSD__) && defined(_STANDALONE) - /* Some kernels are loaded at address 0x0 so strm->next_out could be NULL */ - if (strm == Z_NULL || strm->state == Z_NULL || - (strm->next_in == Z_NULL && strm->avail_in != 0)) - return Z_STREAM_ERROR; -#else - if (strm == Z_NULL || strm->state == Z_NULL || strm->next_out == Z_NULL || - (strm->next_in == Z_NULL && strm->avail_in != 0)) - return Z_STREAM_ERROR; -#endif - - state = (struct inflate_state FAR *)strm->state; - if (state->mode == TYPE) state->mode = TYPEDO; /* skip check */ - LOAD(); - in = have; - out = left; - ret = Z_OK; - for (;;) - switch (state->mode) { - case HEAD: - if (state->wrap == 0) { - state->mode = TYPEDO; - break; - } - NEEDBITS(16); -#ifdef GUNZIP - if ((state->wrap & 2) && hold == 0x8b1f) { /* gzip header */ - state->check = crc32(0L, Z_NULL, 0); - CRC2(state->check, hold); - INITBITS(); - state->mode = FLAGS; - break; - } - state->flags = 0; /* expect zlib header */ - if (state->head != Z_NULL) - state->head->done = -1; - if (!(state->wrap & 1) || /* check if zlib header allowed */ -#else - if ( -#endif - ((BITS(8) << 8) + (hold >> 8)) % 31) { - strm->msg = __UNCONST("incorrect header check"); - state->mode = BAD; - break; - } - if (BITS(4) != Z_DEFLATED) { - strm->msg = __UNCONST("unknown compression method"); - state->mode = BAD; - break; - } - DROPBITS(4); - len = BITS(4) + 8; - if (len > state->wbits) { - strm->msg = __UNCONST("invalid window size"); - state->mode = BAD; - break; - } - state->dmax = 1U << len; - Tracev((stderr, "inflate: zlib header ok\n")); - strm->adler = state->check = adler32(0L, Z_NULL, 0); - state->mode = hold & 0x200 ?

This is more efficient than inflate() for - file i/o applications in that it avoids copying between the output and the - sliding window by simply making the window itself the output buffer. This - function trusts the application to not change the output buffer passed by - the output function, at least until inflateBack() returns. - - inflateBackInit() must be called first to allocate the internal state - and to initialize the state with the user-provided window buffer. - inflateBack() may then be used multiple times to inflate a complete, raw - deflate stream with each call. inflateBackEnd() is then called to free - the allocated state. - - A raw deflate stream is one with no zlib or gzip header or trailer. - This routine would normally be used in a utility that reads zip or gzip - files and writes out uncompressed files. The utility would decode the - header and process the trailer on its own, hence this routine expects - only the raw deflate stream to decompress. This is different from the - normal behavior of inflate(), which expects either a zlib or gzip header and - trailer around the deflate stream. - - inflateBack() uses two subroutines supplied by the caller that are then - called by inflateBack() for input and output. inflateBack() calls those - routines until it reads a complete deflate stream and writes out all of the - uncompressed data, or until it encounters an error. The function's - parameters and return types are defined above in the in_func and out_func - typedefs. inflateBack() will call in(in_desc, &buf) which should return the - number of bytes of provided input, and a pointer to that input in buf. If - there is no input available, in() must return zero--buf is ignored in that - case--and inflateBack() will return a buffer error. inflateBack() will call - out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out() - should return zero on success, or non-zero on failure. If out() returns - non-zero, inflateBack() will return with an error. Neither in() nor out() - are permitted to change the contents of the window provided to - inflateBackInit(), which is also the buffer that out() uses to write from. - The length written by out() will be at most the window size. Any non-zero - amount of input may be provided by in(). - - For convenience, inflateBack() can be provided input on the first call by - setting strm->next_in and strm->avail_in. If that input is exhausted, then - in() will be called. Therefore strm->next_in must be initialized before - calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called - immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in - must also be initialized, and then if strm->avail_in is not zero, input will - initially be taken from strm->next_in[0 .. strm->avail_in - 1]. - - The in_desc and out_desc parameters of inflateBack() is passed as the - first parameter of in() and out() respectively when they are called. These - descriptors can be optionally used to pass any information that the caller- - supplied in() and out() functions need to do their job. - - On return, inflateBack() will set strm->next_in and strm->avail_in to - pass back any unused input that was provided by the last in() call. The - return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR - if in() or out() returned an error, Z_DATA_ERROR if there was a format - error in the deflate stream (in which case strm->msg is set to indicate the - nature of the error), or Z_STREAM_ERROR if the stream was not properly - initialized. In the case of Z_BUF_ERROR, an input or output error can be - distinguished using strm->next_in which will be Z_NULL only if in() returned - an error. If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to - out() returning non-zero.
