Compression algorithm (deflate) - -The deflation algorithm used by gzip (also zip and zlib) is a variation of -LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in -the input data. The second occurrence of a string is replaced by a -pointer to the previous string, in the form of a pair (distance, -length). Distances are limited to 32K bytes, and lengths are limited -to 258 bytes. When a string does not occur anywhere in the previous -32K bytes, it is emitted as a sequence of literal bytes. (In this -description, `string' must be taken as an arbitrary sequence of bytes, -and is not restricted to printable characters.) - -Literals or match lengths are compressed with one Huffman tree, and -match distances are compressed with another tree. The trees are stored -in a compact form at the start of each block. The blocks can have any -size (except that the compressed data for one block must fit in -available memory). A block is terminated when deflate() determines that -it would be useful to start another block with fresh trees. (This is -somewhat similar to the behavior of LZW-based _compress_.) - -Duplicated strings are found using a hash table. All input strings of -length 3 are inserted in the hash table. A hash index is computed for -the next 3 bytes. If the hash chain for this index is not empty, all -strings in the chain are compared with the current input string, and -the longest match is selected. - -The hash chains are searched starting with the most recent strings, to -favor small distances and thus take advantage of the Huffman encoding. -The hash chains are singly linked. There are no deletions from the -hash chains, the algorithm simply discards matches that are too old. - -To avoid a worst-case situation, very long hash chains are arbitrarily -truncated at a certain length, determined by a runtime option (level -parameter of deflateInit). So deflate() does not always find the longest -possible match but generally finds a match which is long enough. - -deflate() also defers the selection of matches with a lazy evaluation -mechanism. After a match of length N has been found, deflate() searches for -a longer match at the next input byte. If a longer match is found, the -previous match is truncated to a length of one (thus producing a single -literal byte) and the process of lazy evaluation begins again. Otherwise, -the original match is kept, and the next match search is attempted only N -steps later. - -The lazy match evaluation is also subject to a runtime parameter. If -the current match is long enough, deflate() reduces the search for a longer -match, thus speeding up the whole process. If compression ratio is more -important than speed, deflate() attempts a complete second search even if -the first match is already long enough. - -The lazy match evaluation is not performed for the fastest compression -modes (level parameter 1 to 3). For these fast modes, new strings -are inserted in the hash table only when no match was found, or -when the match is not too long. This degrades the compression ratio -but saves time since there are both fewer insertions and fewer searches. - - -2. Decompression algorithm (inflate) - -2.1 Introduction - -The key question is how to represent a Huffman code (or any prefix code) so -that you can decode fast. The most important characteristic is that shorter -codes are much more common than longer codes, so pay attention to decoding the -short codes fast, and let the long codes take longer to decode. - -inflate() sets up a first level table that covers some number of bits of -input less than the length of longest code. It gets that many bits from the -stream, and looks it up in the table. The table will tell if the next -code is that many bits or less and how many, and if it is, it will tell -the value, else it will point to the next level table for which inflate() -grabs more bits and tries to decode a longer code. - -How many bits to make the first lookup is a tradeoff between the time it -takes to decode and the time it takes to build the table. If building the -table took no time (and if you had infinite memory), then there would only -be a first level table to cover all the way to the longest code. However, -building the table ends up taking a lot longer for more bits since short -codes are replicated many times in such a table. What inflate() does is -simply to make the number of bits in the first table a variable, and then -to set that variable for the maximum speed. - -For inflate, which has 286 possible codes for the literal/length tree, the size -of the first table is nine bits. Also the distance trees have 30 possible -values, and the size of the first table is six bits. Note that for each of -those cases, the table ended up one bit longer than the ``average'' code -length, i.e. the code length of an approximately flat code which would be a -little more than eight bits for 286 symbols and a little less than five bits -for 30 symbols. - - -2.2 More details on the inflate table lookup - -Ok, you want to know what this cleverly obfuscated inflate tree actually -looks like. You are correct that it's not a Huffman tree. It is simply a -lookup table for the first, let's say, nine bits of a Huffman symbol. The -symbol could be as short as one bit or as long as 15 bits. If a particular -symbol is shorter than nine bits, then that symbol's translation is duplicated -in all those entries that start with that symbol's bits. For example, if the -symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a -symbol is nine bits long, it appears in the table once. - -If the symbol is longer than nine bits, then that entry in the table points -to another similar table for the remaining bits. Again, there are duplicated -entries as needed. The idea is that most of the time the symbol will be short -and there will only be one table look up. (That's whole idea behind data -compression in the first place.) For the less frequent long symbols, there -will be two lookups. If you had a compression method with really long -symbols, you could have as many levels of lookups as is efficient. For -inflate, two is enough. - -So a table entry either points to another table (in which case nine bits in -the above example are gobbled), or it contains the translation for the symbol -and the number of bits to gobble. Then you start again with the next -ungobbled bit. - -You may wonder: why not just have one lookup table for how ever many bits the -longest symbol is? The reason is that if you do that, you end up spending -more time filling in duplicate symbol entries than you do actually decoding. -At least for deflate's output that generates new trees every several 10's of -kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code -would take too long if you're only decoding several thousand symbols. At the -other extreme, you could make a new table for every bit in the code. In fact, -that's essentially a Huffman tree. But then you spend two much time -traversing the tree while decoding, even for short symbols. - -So the number of bits for the first lookup table is a trade of the time to -fill out the table vs. the time spent looking at the second level and above of -the table. - -Here is an example, scaled down: - -The code being decoded, with 10 symbols, from 1 to 6 bits long: - -A: 0 -B: 10 -C: 1100 -D: 11010 -E: 11011 -F: 11100 -G: 11101 -H: 11110 -I: 111110 -J: 111111 - -Let's make the first table three bits long (eight entries): - -000: A,1 -001: A,1 -010: A,1 -011: A,1 -100: B,2 -101: B,2 -110: -> table X (gobble 3 bits) -111: -> table Y (gobble 3 bits) - -Each entry is what the bits decode as and how many bits that is, i.e. how -many bits to gobble. Or the entry points to another table, with the number of -bits to gobble implicit in the size of the table. - -Table X is two bits long since the longest code starting with 110 is five bits -long: - -00: C,1 -01: C,1 -10: D,2 -11: E,2 - -Table Y is three bits long since the longest code starting with 111 is six -bits long: - -000: F,2 -001: F,2 -010: G,2 -011: G,2 -100: H,2 -101: H,2 -110: I,3 -111: J,3 - -So what we have here are three tables with a total of 20 entries that had to -be constructed. That's compared to 64 entries for a single table. Or -compared to 16 entries for a Huffman tree (six two entry tables and one four -entry table). Assuming that the code ideally represents the probability of -the symbols, it takes on the average 1.25 lookups per symbol. That's compared -to one lookup for the single table, or 1.66 lookups per symbol for the -Huffman tree. - -There, I think that gives you a picture of what's going on. For inflate, the -meaning of a particular symbol is often more than just a letter. It can be a -byte (a "literal"), or it can be either a length or a distance which -indicates a base value and a number of bits to fetch after the code that is -added to the base value.

Compression algorithm (deflate) + +The deflation algorithm used by gzip (also zip and zlib) is a variation of +LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in +the input data. The second occurrence of a string is replaced by a +pointer to the previous string, in the form of a pair (distance, +length). Distances are limited to 32K bytes, and lengths are limited +to 258 bytes. When a string does not occur anywhere in the previous +32K bytes, it is emitted as a sequence of literal bytes. (In this +description, `string' must be taken as an arbitrary sequence of bytes, +and is not restricted to printable characters.) + +Literals or match lengths are compressed with one Huffman tree, and +match distances are compressed with another tree. The trees are stored +in a compact form at the start of each block. The blocks can have any +size (except that the compressed data for one block must fit in +available memory). A block is terminated when deflate() determines that +it would be useful to start another block with fresh trees. (This is +somewhat similar to the behavior of LZW-based _compress_.) + +Duplicated strings are found using a hash table. All input strings of +length 3 are inserted in the hash table. A hash index is computed for +the next 3 bytes. If the hash chain for this index is not empty, all +strings in the chain are compared with the current input string, and +the longest match is selected. + +The hash chains are searched starting with the most recent strings, to +favor small distances and thus take advantage of the Huffman encoding. +The hash chains are singly linked. There are no deletions from the +hash chains, the algorithm simply discards matches that are too old. + +To avoid a worst-case situation, very long hash chains are arbitrarily +truncated at a certain length, determined by a runtime option (level +parameter of deflateInit). So deflate() does not always find the longest +possible match but generally finds a match which is long enough. + +deflate() also defers the selection of matches with a lazy evaluation +mechanism. After a match of length N has been found, deflate() searches for +a longer match at the next input byte. If a longer match is found, the +previous match is truncated to a length of one (thus producing a single +literal byte) and the process of lazy evaluation begins again. Otherwise, +the original match is kept, and the next match search is attempted only N +steps later. + +The lazy match evaluation is also subject to a runtime parameter. If +the current match is long enough, deflate() reduces the search for a longer +match, thus speeding up the whole process. If compression ratio is more +important than speed, deflate() attempts a complete second search even if +the first match is already long enough. + +The lazy match evaluation is not performed for the fastest compression +modes (level parameter 1 to 3). For these fast modes, new strings +are inserted in the hash table only when no match was found, or +when the match is not too long. This degrades the compression ratio +but saves time since there are both fewer insertions and fewer searches. + + +2. Decompression algorithm (inflate) + +2.1 Introduction + +The key question is how to represent a Huffman code (or any prefix code) so +that you can decode fast. The most important characteristic is that shorter +codes are much more common than longer codes, so pay attention to decoding the +short codes fast, and let the long codes take longer to decode. + +inflate() sets up a first level table that covers some number of bits of +input less than the length of longest code. It gets that many bits from the +stream, and looks it up in the table. The table will tell if the next +code is that many bits or less and how many, and if it is, it will tell +the value, else it will point to the next level table for which inflate() +grabs more bits and tries to decode a longer code. + +How many bits to make the first lookup is a tradeoff between the time it +takes to decode and the time it takes to build the table. If building the +table took no time (and if you had infinite memory), then there would only +be a first level table to cover all the way to the longest code. However, +building the table ends up taking a lot longer for more bits since short +codes are replicated many times in such a table. What inflate() does is +simply to make the number of bits in the first table a variable, and then +to set that variable for the maximum speed. + +For inflate, which has 286 possible codes for the literal/length tree, the size +of the first table is nine bits. Also the distance trees have 30 possible +values, and the size of the first table is six bits. Note that for each of +those cases, the table ended up one bit longer than the ``average'' code +length, i.e. the code length of an approximately flat code which would be a +little more than eight bits for 286 symbols and a little less than five bits +for 30 symbols. + + +2.2 More details on the inflate table lookup + +Ok, you want to know what this cleverly obfuscated inflate tree actually +looks like. You are correct that it's not a Huffman tree. It is simply a +lookup table for the first, let's say, nine bits of a Huffman symbol. The +symbol could be as short as one bit or as long as 15 bits. If a particular +symbol is shorter than nine bits, then that symbol's translation is duplicated +in all those entries that start with that symbol's bits. For example, if the +symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a +symbol is nine bits long, it appears in the table once. + +If the symbol is longer than nine bits, then that entry in the table points +to another similar table for the remaining bits. Again, there are duplicated +entries as needed. The idea is that most of the time the symbol will be short +and there will only be one table look up. (That's whole idea behind data +compression in the first place.) For the less frequent long symbols, there +will be two lookups. If you had a compression method with really long +symbols, you could have as many levels of lookups as is efficient. For +inflate, two is enough. + +So a table entry either points to another table (in which case nine bits in +the above example are gobbled), or it contains the translation for the symbol +and the number of bits to gobble. Then you start again with the next +ungobbled bit. + +You may wonder: why not just have one lookup table for how ever many bits the +longest symbol is? The reason is that if you do that, you end up spending +more time filling in duplicate symbol entries than you do actually decoding. +At least for deflate's output that generates new trees every several 10's of +kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code +would take too long if you're only decoding several thousand symbols. At the +other extreme, you could make a new table for every bit in the code. In fact, +that's essentially a Huffman tree. But then you spend too much time +traversing the tree while decoding, even for short symbols. + +So the number of bits for the first lookup table is a trade of the time to +fill out the table vs. the time spent looking at the second level and above of +the table. + +Here is an example, scaled down: + +The code being decoded, with 10 symbols, from 1 to 6 bits long: + +A: 0 +B: 10 +C: 1100 +D: 11010 +E: 11011 +F: 11100 +G: 11101 +H: 11110 +I: 111110 +J: 111111 + +Let's make the first table three bits long (eight entries): + +000: A,1 +001: A,1 +010: A,1 +011: A,1 +100: B,2 +101: B,2 +110: -> table X (gobble 3 bits) +111: -> table Y (gobble 3 bits) + +Each entry is what the bits decode as and how many bits that is, i.e. how +many bits to gobble. Or the entry points to another table, with the number of +bits to gobble implicit in the size of the table. + +Table X is two bits long since the longest code starting with 110 is five bits +long: + +00: C,1 +01: C,1 +10: D,2 +11: E,2 + +Table Y is three bits long since the longest code starting with 111 is six +bits long: + +000: F,2 +001: F,2 +010: G,2 +011: G,2 +100: H,2 +101: H,2 +110: I,3 +111: J,3 + +So what we have here are three tables with a total of 20 entries that had to +be constructed. That's compared to 64 entries for a single table. Or +compared to 16 entries for a Huffman tree (six two entry tables and one four +entry table). Assuming that the code ideally represents the probability of +the symbols, it takes on the average 1.25 lookups per symbol. That's compared +to one lookup for the single table, or 1.66 lookups per symbol for the +Huffman tree. + +There, I think that gives you a picture of what's going on. For inflate, the +meaning of a particular symbol is often more than just a letter. It can be a +byte (a "literal"), or it can be either a length or a distance which +indicates a base value and a number of bits to fetch after the code that is +added to the base value. Or it might be the special end-of-block code.

Scope + + The specification specifies a compressed data format that can be + used for in-memory compression of a sequence of arbitrary bytes. + + 1.4. Compliance + + Unless otherwise indicated below, a compliant decompressor must be + able to accept and decompress any data set that conforms to all + the specifications presented here; a compliant compressor must + produce data sets that conform to all the specifications presented + here. + + 1.5.

Changes from previous versions + + Version 3.1 was the first public release of this specification. + In version 3.2, some terminology was changed and the Adler-32 + sample code was rewritten for clarity.

Preset dictionaries + + A preset dictionary is specially useful to compress short input + sequences. The compressor can take advantage of the dictionary + context to encode the input in a more compact manner. The + decompressor can be initialized with the appropriate context by + virtually decompressing a compressed version of the dictionary + without producing any output. However for certain compression + algorithms such as the deflate algorithm this operation can be + achieved without actually performing any decompression. + + The compressor and the decompressor must use exactly the same + dictionary. The dictionary may be fixed or may be chosen among a + certain number of predefined dictionaries, according to the kind + of input data. The decompressor can determine which dictionary has + been chosen by the compressor by checking the dictionary + identifier. This document does not specify the contents of + predefined dictionaries, since the optimal dictionaries are + application specific. Standard data formats using this feature of + the zlib specification must precisely define the allowed + dictionaries. + + 8.2. The Adler-32 algorithm + + The Adler-32 algorithm is much faster than the CRC32 algorithm yet + still provides an extremely low probability of undetected errors. + + The modulo on unsigned long accumulators can be delayed for 5552 + bytes, so the modulo operation time is negligible. If the bytes + are a, b, c, the second sum is 3a + 2b + c + 3, and so is position + and order sensitive, unlike the first sum, which is just a + checksum. That 65521 is prime is important to avoid a possible + large class of two-byte errors that leave the check unchanged. + (The Fletcher checksum uses 255, which is not prime and which also + makes the Fletcher check insensitive to single byte changes 0 <-> + 255.) + + The sum s1 is initialized to 1 instead of zero to make the length + of the sequence part of s2, so that the length does not have to be + checked separately.

Purpose + + The purpose of this specification is to define a lossless + compressed data format that: + * Is independent of CPU type, operating system, file system, + and character set, and hence can be used for interchange; + * Can be produced or consumed, even for an arbitrarily long + sequentially presented input data stream, using only an a + priori bounded amount of intermediate storage, and hence + can be used in data communications or similar structures + such as Unix filters; + * Compresses data with efficiency comparable to the best + currently available general-purpose compression methods, + and in particular considerably better than the "compress" + program; + * Can be implemented readily in a manner not covered by + patents, and hence can be practiced freely; + + + +Deutsch Informational [Page 2] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + * Is compatible with the file format produced by the current + widely used gzip utility, in that conforming decompressors + will be able to read data produced by the existing gzip + compressor. + + The data format defined by this specification does not attempt to: + + * Allow random access to compressed data; + * Compress specialized data (e.g., raster graphics) as well + as the best currently available specialized algorithms. + + A simple counting argument shows that no lossless compression + algorithm can compress every possible input data set. For the + format defined here, the worst case expansion is 5 bytes per 32K- + byte block, i.e., a size increase of 0.015% for large data sets. + English text usually compresses by a factor of 2.5 to 3; + executable files usually compress somewhat less; graphical data + such as raster images may compress much more. + + 1.2. Intended audience + + This specification is intended for use by implementors of software + to compress data into "deflate" format and/or decompress data from + "deflate" format. + + The text of the specification assumes a basic background in + programming at the level of bits and other primitive data + representations. Familiarity with the technique of Huffman coding + is helpful but not required. + + 1.3. Scope + + The specification specifies a method for representing a sequence + of bytes as a (usually shorter) sequence of bits, and a method for + packing the latter bit sequence into bytes. + + 1.4. Compliance + + Unless otherwise indicated below, a compliant decompressor must be + able to accept and decompress any data set that conforms to all + the specifications presented here; a compliant compressor must + produce data sets that conform to all the specifications presented + here. + + 1.5. Definitions of terms and conventions used + + Byte: 8 bits stored or transmitted as a unit (same as an octet). + For this specification, a byte is exactly 8 bits, even on machines + + + +Deutsch Informational [Page 3] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + which store a character on a number of bits different from eight. + See below, for the numbering of bits within a byte. + + String: a sequence of arbitrary bytes. + + 1.6. Changes from previous versions + + There have been no technical changes to the deflate format since + version 1.1 of this specification. In version 1.2, some + terminology was changed. Version 1.3 is a conversion of the + specification to RFC style. + +2. Compressed representation overview + + A compressed data set consists of a series of blocks, corresponding + to successive blocks of input data. The block sizes are arbitrary, + except that non-compressible blocks are limited to 65,535 bytes. + + Each block is compressed using a combination of the LZ77 algorithm + and Huffman coding. The Huffman trees for each block are independent + of those for previous or subsequent blocks; the LZ77 algorithm may + use a reference to a duplicated string occurring in a previous block, + up to 32K input bytes before. + + Each block consists of two parts: a pair of Huffman code trees that + describe the representation of the compressed data part, and a + compressed data part. (The Huffman trees themselves are compressed + using Huffman encoding.) The compressed data consists of a series of + elements of two types: literal bytes (of strings that have not been + detected as duplicated within the previous 32K input bytes), and + pointers to duplicated strings, where a pointer is represented as a + pair . The representation used in the + "deflate" format limits distances to 32K bytes and lengths to 258 + bytes, but does not limit the size of a block, except for + uncompressible blocks, which are limited as noted above. + + Each type of value (literals, distances, and lengths) in the + compressed data is represented using a Huffman code, using one code + tree for literals and lengths and a separate code tree for distances. + The code trees for each block appear in a compact form just before + the compressed data for that block. + + + + + + + + + + +Deutsch Informational [Page 4] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + +3. Detailed specification + + 3.1. Overall conventions In the diagrams below, a box like this: + + +---+ + | | <-- the vertical bars might be missing + +---+ + + represents one byte; a box like this: + + +==============+ + | | + +==============+ + + represents a variable number of bytes. + + Bytes stored within a computer do not have a "bit order", since + they are always treated as a unit. However, a byte considered as + an integer between 0 and 255 does have a most- and least- + significant bit, and since we write numbers with the most- + significant digit on the left, we also write bytes with the most- + significant bit on the left. In the diagrams below, we number the + bits of a byte so that bit 0 is the least-significant bit, i.e., + the bits are numbered: + + +--------+ + |76543210| + +--------+ + + Within a computer, a number may occupy multiple bytes. All + multi-byte numbers in the format described here are stored with + the least-significant byte first (at the lower memory address). + For example, the decimal number 520 is stored as: + + 0 1 + +--------+--------+ + |00001000|00000010| + +--------+--------+ + ^ ^ + | | + | + more significant byte = 2 x 256 + + less significant byte = 8 + + 3.1.1. Packing into bytes + + This document does not address the issue of the order in which + bits of a byte are transmitted on a bit-sequential medium, + since the final data format described here is byte- rather than + + + +Deutsch Informational [Page 5] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + bit-oriented. However, we describe the compressed block format + in below, as a sequence of data elements of various bit + lengths, not a sequence of bytes. We must therefore specify + how to pack these data elements into bytes to form the final + compressed byte sequence: + + * Data elements are packed into bytes in order of + increasing bit number within the byte, i.e., starting + with the least-significant bit of the byte. + * Data elements other than Huffman codes are packed + starting with the least-significant bit of the data + element. + * Huffman codes are packed starting with the most- + significant bit of the code. + + In other words, if one were to print out the compressed data as + a sequence of bytes, starting with the first byte at the + *right* margin and proceeding to the *left*, with the most- + significant bit of each byte on the left as usual, one would be + able to parse the result from right to left, with fixed-width + elements in the correct MSB-to-LSB order and Huffman codes in + bit-reversed order (i.e., with the first bit of the code in the + relative LSB position). + + 3.2. Compressed block format + + 3.2.1. Synopsis of prefix and Huffman coding + + Prefix coding represents symbols from an a priori known + alphabet by bit sequences (codes), one code for each symbol, in + a manner such that different symbols may be represented by bit + sequences of different lengths, but a parser can always parse + an encoded string unambiguously symbol-by-symbol. + + We define a prefix code in terms of a binary tree in which the + two edges descending from each non-leaf node are labeled 0 and + 1 and in which the leaf nodes correspond one-for-one with (are + labeled with) the symbols of the alphabet; then the code for a + symbol is the sequence of 0's and 1's on the edges leading from + the root to the leaf labeled with that symbol. For example: + + + + + + + + + + + +Deutsch Informational [Page 6] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + /\ Symbol Code + 0 1 ------ ---- + / \ A 00 + /\ B B 1 + 0 1 C 011 + / \ D 010 + A /\ + 0 1 + / \ + D C + + A parser can decode the next symbol from an encoded input + stream by walking down the tree from the root, at each step + choosing the edge corresponding to the next input bit. + + Given an alphabet with known symbol frequencies, the Huffman + algorithm allows the construction of an optimal prefix code + (one which represents strings with those symbol frequencies + using the fewest bits of any possible prefix codes for that + alphabet). Such a code is called a Huffman code. (See + reference [1] in Chapter 5, references for additional + information on Huffman codes.) + + Note that in the "deflate" format, the Huffman codes for the + various alphabets must not exceed certain maximum code lengths. + This constraint complicates the algorithm for computing code + lengths from symbol frequencies. Again, see Chapter 5, + references for details. + + 3.2.2. Use of Huffman coding in the "deflate" format + + The Huffman codes used for each alphabet in the "deflate" + format have two additional rules: + + * All codes of a given bit length have lexicographically + consecutive values, in the same order as the symbols + they represent; + + * Shorter codes lexicographically precede longer codes. + + + + + + + + + + + + +Deutsch Informational [Page 7] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + We could recode the example above to follow this rule as + follows, assuming that the order of the alphabet is ABCD: + + Symbol Code + ------ ---- + A 10 + B 0 + C 110 + D 111 + + I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are + lexicographically consecutive. + + Given this rule, we can define the Huffman code for an alphabet + just by giving the bit lengths of the codes for each symbol of + the alphabet in order; this is sufficient to determine the + actual codes. In our example, the code is completely defined + by the sequence of bit lengths (2, 1, 3, 3). The following + algorithm generates the codes as integers, intended to be read + from most- to least-significant bit. The code lengths are + initially in tree[I].Len; the codes are produced in + tree[I].Code. + + 1) Count the number of codes for each code length. Let + bl_count[N] be the number of codes of length N, N >= 1. + + 2) Find the numerical value of the smallest code for each + code length: + + code = 0; + bl_count[0] = 0; + for (bits = 1; bits <= MAX_BITS; bits++) { + code = (code + bl_count[bits-1]) << 1; + next_code[bits] = code; + } + + 3) Assign numerical values to all codes, using consecutive + values for all codes of the same length with the base + values determined at step 2. Codes that are never used + (which have a bit length of zero) must not be assigned a + value. + + for (n = 0; n <= max_code; n++) { + len = tree[n].Len; + if (len != 0) { + tree[n].Code = next_code[len]; + next_code[len]++; + } + + + +Deutsch Informational [Page 8] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + } + + Example: + + Consider the alphabet ABCDEFGH, with bit lengths (3, 3, 3, 3, + 3, 2, 4, 4). After step 1, we have: + + N bl_count[N] + - ----------- + 2 1 + 3 5 + 4 2 + + Step 2 computes the following next_code values: + + N next_code[N] + - ------------ + 1 0 + 2 0 + 3 2 + 4 14 + + Step 3 produces the following code values: + + Symbol Length Code + ------ ------ ---- + A 3 010 + B 3 011 + C 3 100 + D 3 101 + E 3 110 + F 2 00 + G 4 1110 + H 4 1111 + + 3.2.3. Details of block format + + Each block of compressed data begins with 3 header bits + containing the following data: + + first bit BFINAL + next 2 bits BTYPE + + Note that the header bits do not necessarily begin on a byte + boundary, since a block does not necessarily occupy an integral + number of bytes. + + + + + +Deutsch Informational [Page 9] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + BFINAL is set if and only if this is the last block of the data + set. + + BTYPE specifies how the data are compressed, as follows: + + 00 - no compression + 01 - compressed with fixed Huffman codes + 10 - compressed with dynamic Huffman codes + 11 - reserved (error) + + The only difference between the two compressed cases is how the + Huffman codes for the literal/length and distance alphabets are + defined. + + In all cases, the decoding algorithm for the actual data is as + follows: + + do + read block header from input stream. + if stored with no compression + skip any remaining bits in current partially + processed byte + read LEN and NLEN (see next section) + copy LEN bytes of data to output + otherwise + if compressed with dynamic Huffman codes + read representation of code trees (see + subsection below) + loop (until end of block code recognized) + decode literal/length value from input stream + if value < 256 + copy value (literal byte) to output stream + otherwise + if value = end of block (256) + break from loop + otherwise (value = 257..285) + decode distance from input stream + + move backwards distance bytes in the output + stream, and copy length bytes from this + position to the output stream. + end loop + while not last block + + Note that a duplicated string reference may refer to a string + in a previous block; i.e., the backward distance may cross one + or more block boundaries. However a distance cannot refer past + the beginning of the output stream. (An application using a + + + +Deutsch Informational [Page 10] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + preset dictionary might discard part of the output stream; a + distance can refer to that part of the output stream anyway) + Note also that the referenced string may overlap the current + position; for example, if the last 2 bytes decoded have values + X and Y, a string reference with + adds X,Y,X,Y,X to the output stream. + + We now specify each compression method in turn. + + 3.2.4. Non-compressed blocks (BTYPE=00) + + Any bits of input up to the next byte boundary are ignored. + The rest of the block consists of the following information: + + 0 1 2 3 4... + +---+---+---+---+================================+ + | LEN | NLEN |... LEN bytes of literal data...| + +---+---+---+---+================================+ + + LEN is the number of data bytes in the block. NLEN is the + one's complement of LEN. + + 3.2.5. Compressed blocks (length and distance codes) + + As noted above, encoded data blocks in the "deflate" format + consist of sequences of symbols drawn from three conceptually + distinct alphabets: either literal bytes, from the alphabet of + byte values (0..255), or pairs, + where the length is drawn from (3..258) and the distance is + drawn from (1..32,768). In fact, the literal and length + alphabets are merged into a single alphabet (0..285), where + values 0..255 represent literal bytes, the value 256 indicates + end-of-block, and values 257..285 represent length codes + (possibly in conjunction with extra bits following the symbol + code) as follows: + + + + + + + + + + + + + + + + +Deutsch Informational [Page 11] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + Extra Extra Extra + Code Bits Length(s) Code Bits Lengths Code Bits Length(s) + ---- ---- ------ ---- ---- ------- ---- ---- ------- + 257 0 3 267 1 15,16 277 4 67-82 + 258 0 4 268 1 17,18 278 4 83-98 + 259 0 5 269 2 19-22 279 4 99-114 + 260 0 6 270 2 23-26 280 4 115-130 + 261 0 7 271 2 27-30 281 5 131-162 + 262 0 8 272 2 31-34 282 5 163-194 + 263 0 9 273 3 35-42 283 5 195-226 + 264 0 10 274 3 43-50 284 5 227-257 + 265 1 11,12 275 3 51-58 285 0 258 + 266 1 13,14 276 3 59-66 + + The extra bits should be interpreted as a machine integer + stored with the most-significant bit first, e.g., bits 1110 + represent the value 14. + + Extra Extra Extra + Code Bits Dist Code Bits Dist Code Bits Distance + ---- ---- ---- ---- ---- ------ ---- ---- -------- + 0 0 1 10 4 33-48 20 9 1025-1536 + 1 0 2 11 4 49-64 21 9 1537-2048 + 2 0 3 12 5 65-96 22 10 2049-3072 + 3 0 4 13 5 97-128 23 10 3073-4096 + 4 1 5,6 14 6 129-192 24 11 4097-6144 + 5 1 7,8 15 6 193-256 25 11 6145-8192 + 6 2 9-12 16 7 257-384 26 12 8193-12288 + 7 2 13-16 17 7 385-512 27 12 12289-16384 + 8 3 17-24 18 8 513-768 28 13 16385-24576 + 9 3 25-32 19 8 769-1024 29 13 24577-32768 + + 3.2.6. Compression with fixed Huffman codes (BTYPE=01) + + The Huffman codes for the two alphabets are fixed, and are not + represented explicitly in the data.

Literal/length values 286-287 will never actually + occur in the compressed data, but participate in the code + construction. + + Distance codes 0-31 are represented by (fixed-length) 5-bit + codes, with possible additional bits as shown in the table + shown in Paragraph 3.2.5, above. Note that distance codes 30- + 31 will never actually occur in the compressed data. + + 3.2.7. Compression with dynamic Huffman codes (BTYPE=10) + + The Huffman codes for the two alphabets appear in the block + immediately after the header bits and before the actual + compressed data, first the literal/length code and then the + distance code. Each code is defined by a sequence of code + lengths, as discussed in Paragraph 3.2.2, above. For even + greater compactness, the code length sequences themselves are + compressed using a Huffman code. The alphabet for code lengths + is as follows: + + 0 - 15: Represent code lengths of 0 - 15 + 16: Copy the previous code length 3 - 6 times. + The next 2 bits indicate repeat length + (0 = 3, ... , 3 = 6) + Example: Codes 8, 16 (+2 bits 11), + 16 (+2 bits 10) will expand to + 12 code lengths of 8 (1 + 6 + 5) + 17: Repeat a code length of 0 for 3 - 10 times. + (3 bits of length) + 18: Repeat a code length of 0 for 11 - 138 times + (7 bits of length) + + A code length of 0 indicates that the corresponding symbol in + the literal/length or distance alphabet will not occur in the + block, and should not participate in the Huffman code + construction algorithm given earlier. If only one distance + code is used, it is encoded using one bit, not zero bits; in + this case there is a single code length of one, with one unused + code. One distance code of zero bits means that there are no + distance codes used at all (the data is all literals). + + We can now define the format of the block: + + 5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286) + 5 Bits: HDIST, # of Distance codes - 1 (1 - 32) + 4 Bits: HCLEN, # of Code Length codes - 4 (4 - 19) + + + +Deutsch Informational [Page 13] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + (HCLEN + 4) x 3 bits: code lengths for the code length + alphabet given just above, in the order: 16, 17, 18, + 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15 + + These code lengths are interpreted as 3-bit integers + (0-7); as above, a code length of 0 means the + corresponding symbol (literal/length or distance code + length) is not used. + + HLIT + 257 code lengths for the literal/length alphabet, + encoded using the code length Huffman code + + HDIST + 1 code lengths for the distance alphabet, + encoded using the code length Huffman code + + The actual compressed data of the block, + encoded using the literal/length and distance Huffman + codes + + The literal/length symbol 256 (end of data), + encoded using the literal/length Huffman code + + The code length repeat codes can cross from HLIT + 257 to the + HDIST + 1 code lengths. In other words, all code lengths form + a single sequence of HLIT + HDIST + 258 values. + + 3.3. Compliance + + A compressor may limit further the ranges of values specified in + the previous section and still be compliant; for example, it may + limit the range of backward pointers to some value smaller than + 32K. Similarly, a compressor may limit the size of blocks so that + a compressible block fits in memory. + + A compliant decompressor must accept the full range of possible + values defined in the previous section, and must accept blocks of + arbitrary size. + +4. Compression algorithm details + + While it is the intent of this document to define the "deflate" + compressed data format without reference to any particular + compression algorithm, the format is related to the compressed + formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below); + since many variations of LZ77 are patented, it is strongly + recommended that the implementor of a compressor follow the general + algorithm presented here, which is known not to be patented per se. + The material in this section is not part of the definition of the + + + +Deutsch Informational [Page 14] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + + specification per se, and a compressor need not follow it in order to + be compliant. + + The compressor terminates a block when it determines that starting a + new block with fresh trees would be useful, or when the block size + fills up the compressor's block buffer. + + The compressor uses a chained hash table to find duplicated strings, + using a hash function that operates on 3-byte sequences. At any + given point during compression, let XYZ be the next 3 input bytes to + be examined (not necessarily all different, of course). First, the + compressor examines the hash chain for XYZ. If the chain is empty, + the compressor simply writes out X as a literal byte and advances one + byte in the input. If the hash chain is not empty, indicating that + the sequence XYZ (or, if we are unlucky, some other 3 bytes with the + same hash function value) has occurred recently, the compressor + compares all strings on the XYZ hash chain with the actual input data + sequence starting at the current point, and selects the longest + match. + + The compressor searches the hash chains starting with the most recent + strings, to favor small distances and thus take advantage of the + Huffman encoding. The hash chains are singly linked. There are no + deletions from the hash chains; the algorithm simply discards matches + that are too old. To avoid a worst-case situation, very long hash + chains are arbitrarily truncated at a certain length, determined by a + run-time parameter. + + To improve overall compression, the compressor optionally defers the + selection of matches ("lazy matching"): after a match of length N has + been found, the compressor searches for a longer match starting at + the next input byte. If it finds a longer match, it truncates the + previous match to a length of one (thus producing a single literal + byte) and then emits the longer match. Otherwise, it emits the + original match, and, as described above, advances N bytes before + continuing. + + Run-time parameters also control this "lazy match" procedure. If + compression ratio is most important, the compressor attempts a + complete second search regardless of the length of the first match. + In the normal case, if the current match is "long enough", the + compressor reduces the search for a longer match, thus speeding up + the process. If speed is most important, the compressor inserts new + strings in the hash table only when no match was found, or when the + match is not "too long". This degrades the compression ratio but + saves time since there are both fewer insertions and fewer searches. + + + + + +Deutsch Informational [Page 15] + +RFC 1951 DEFLATE Compressed Data Format Specification May 1996 + + +5.

Purpose + + The purpose of this specification is to define a lossless + compressed data format that: + + * Is independent of CPU type, operating system, file system, + and character set, and hence can be used for interchange; + * Can compress or decompress a data stream (as opposed to a + randomly accessible file) to produce another data stream, + using only an a priori bounded amount of intermediate + storage, and hence can be used in data communications or + similar structures such as Unix filters; + * Compresses data with efficiency comparable to the best + currently available general-purpose compression methods, + and in particular considerably better than the "compress" + program; + * Can be implemented readily in a manner not covered by + patents, and hence can be practiced freely; + * Is compatible with the file format produced by the current + widely used gzip utility, in that conforming decompressors + will be able to read data produced by the existing gzip + compressor. + + + + +Deutsch Informational [Page 2] + +RFC 1952 GZIP File Format Specification May 1996 + + + The data format defined by this specification does not attempt to: + + * Provide random access to compressed data; + * Compress specialized data (e.g., raster graphics) as well as + the best currently available specialized algorithms. + + 1.2. Intended audience + + This specification is intended for use by implementors of software + to compress data into gzip format and/or decompress data from gzip + format. + + The text of the specification assumes a basic background in + programming at the level of bits and other primitive data + representations. + + 1.3. Scope + + The specification specifies a compression method and a file format + (the latter assuming only that a file can store a sequence of + arbitrary bytes). It does not specify any particular interface to + a file system or anything about character sets or encodings + (except for file names and comments, which are optional). + + 1.4. Compliance + + Unless otherwise indicated below, a compliant decompressor must be + able to accept and decompress any file that conforms to all the + specifications presented here; a compliant compressor must produce + files that conform to all the specifications presented here. The + material in the appendices is not part of the specification per se + and is not relevant to compliance. + + 1.5. Definitions of terms and conventions used + + byte: 8 bits stored or transmitted as a unit (same as an octet). + (For this specification, a byte is exactly 8 bits, even on + machines which store a character on a number of bits different + from 8.) See below for the numbering of bits within a byte. + + 1.6. Changes from previous versions + + There have been no technical changes to the gzip format since + version 4.1 of this specification. In version 4.2, some + terminology was changed, and the sample CRC code was rewritten for + clarity and to eliminate the requirement for the caller to do pre- + and post-conditioning. Version 4.3 is a conversion of the + specification to RFC style. + + + +Deutsch Informational [Page 3] + +RFC 1952 GZIP File Format Specification May 1996 + + +2. Detailed specification + + 2.1. Overall conventions + + In the diagrams below, a box like this: + + +---+ + | | <-- the vertical bars might be missing + +---+ + + represents one byte; a box like this: + + +==============+ + | | + +==============+ + + represents a variable number of bytes. + + Bytes stored within a computer do not have a "bit order", since + they are always treated as a unit. However, a byte considered as + an integer between 0 and 255 does have a most- and least- + significant bit, and since we write numbers with the most- + significant digit on the left, we also write bytes with the most- + significant bit on the left. In the diagrams below, we number the + bits of a byte so that bit 0 is the least-significant bit, i.e., + the bits are numbered: + + +--------+ + |76543210| + +--------+ + + This document does not address the issue of the order in which + bits of a byte are transmitted on a bit-sequential medium, since + the data format described here is byte- rather than bit-oriented. + + Within a computer, a number may occupy multiple bytes. All + multi-byte numbers in the format described here are stored with + the least-significant byte first (at the lower memory address). + For example, the decimal number 520 is stored as: + + 0 1 + +--------+--------+ + |00001000|00000010| + +--------+--------+ + ^ ^ + | | + | + more significant byte = 2 x 256 + + less significant byte = 8 + + + +Deutsch Informational [Page 4] + +RFC 1952 GZIP File Format Specification May 1996 + + + 2.2. File format + + A gzip file consists of a series of "members" (compressed data + sets). The format of each member is specified in the following + section. The members simply appear one after another in the file, + with no additional information before, between, or after them. + + 2.3. Member format + + Each member has the following structure: + + +---+---+---+---+---+---+---+---+---+---+ + |ID1|ID2|CM |FLG| MTIME |XFL|OS | (more-->) + +---+---+---+---+---+---+---+---+---+---+ + + (if FLG.FEXTRA set) + + +---+---+=================================+ + | XLEN |...XLEN bytes of "extra field"...| (more-->) + +---+---+=================================+ + + (if FLG.FNAME set) + + +=========================================+ + |...original file name, zero-terminated...| (more-->) + +=========================================+ + + (if FLG.FCOMMENT set) + + +===================================+ + |...file comment, zero-terminated...| (more-->) + +===================================+ + + (if FLG.FHCRC set) + + +---+---+ + | CRC16 | + +---+---+ + + +=======================+ + |...compressed blocks...| (more-->) + +=======================+ + + 0 1 2 3 4 5 6 7 + +---+---+---+---+---+---+---+---+ + | CRC32 | ISIZE | + +---+---+---+---+---+---+---+---+ + + + + +Deutsch Informational [Page 5] + +RFC 1952 GZIP File Format Specification May 1996 + + + 2.3.1. Member header and trailer + + ID1 (IDentification 1) + ID2 (IDentification 2) + These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139 + (0x8b, \213), to identify the file as being in gzip format. + + CM (Compression Method) + This identifies the compression method used in the file. CM + = 0-7 are reserved. CM = 8 denotes the "deflate" + compression method, which is the one customarily used by + gzip and which is documented elsewhere. + + FLG (FLaGs) + This flag byte is divided into individual bits as follows: + + bit 0 FTEXT + bit 1 FHCRC + bit 2 FEXTRA + bit 3 FNAME + bit 4 FCOMMENT + bit 5 reserved + bit 6 reserved + bit 7 reserved + + If FTEXT is set, the file is probably ASCII text. This is + an optional indication, which the compressor may set by + checking a small amount of the input data to see whether any + non-ASCII characters are present. In case of doubt, FTEXT + is cleared, indicating binary data. For systems which have + different file formats for ascii text and binary data, the + decompressor can use FTEXT to choose the appropriate format. + We deliberately do not specify the algorithm used to set + this bit, since a compressor always has the option of + leaving it cleared and a decompressor always has the option + of ignoring it and letting some other program handle issues + of data conversion. + + If FHCRC is set, a CRC16 for the gzip header is present, + immediately before the compressed data. The CRC16 consists + of the two least significant bytes of the CRC32 for all + bytes of the gzip header up to and not including the CRC16. + [The FHCRC bit was never set by versions of gzip up to + 1.2.4, even though it was documented with a different + meaning in gzip 1.2.4.] + + If FEXTRA is set, optional extra fields are present, as + described in a following section. + + + +Deutsch Informational [Page 6] + +RFC 1952 GZIP File Format Specification May 1996 + + + If FNAME is set, an original file name is present, + terminated by a zero byte. The name must consist of ISO + 8859-1 (LATIN-1) characters; on operating systems using + EBCDIC or any other character set for file names, the name + must be translated to the ISO LATIN-1 character set. This + is the original name of the file being compressed, with any + directory components removed, and, if the file being + compressed is on a file system with case insensitive names, + forced to lower case. There is no original file name if the + data was compressed from a source other than a named file; + for example, if the source was stdin on a Unix system, there + is no file name. + + If FCOMMENT is set, a zero-terminated file comment is + present. This comment is not interpreted; it is only + intended for human consumption. The comment must consist of + ISO 8859-1 (LATIN-1) characters. Line breaks should be + denoted by a single line feed character (10 decimal). + + Reserved FLG bits must be zero. + + MTIME (Modification TIME) + This gives the most recent modification time of the original + file being compressed. The time is in Unix format, i.e., + seconds since 00:00:00 GMT, Jan. 1, 1970. (Note that this + may cause problems for MS-DOS and other systems that use + local rather than Universal time.) If the compressed data + did not come from a file, MTIME is set to the time at which + compression started. MTIME = 0 means no time stamp is + available. + + XFL (eXtra FLags) + These flags are available for use by specific compression + methods. The "deflate" method (CM = 8) sets these flags as + follows: + + XFL = 2 - compressor used maximum compression, + slowest algorithm + XFL = 4 - compressor used fastest algorithm + + OS (Operating System) + This identifies the type of file system on which compression + took place.

The compressor must set all reserved + bits to zero. + + A compliant decompressor must check ID1, ID2, and CM, and + provide an error indication if any of these have incorrect + values. It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC + at least so it can skip over the optional fields if they are + present. It need not examine any other part of the header or + trailer; in particular, a decompressor may ignore FTEXT and OS + and always produce binary output, and still be compliant. A + compliant decompressor must give an error indication if any + reserved bit is non-zero, since such a bit could indicate the + presence of a new field that would cause subsequent data to be + interpreted incorrectly. + +3.

Although +this may appear like a simple task, a fully accurate detection of the +file type requires heavy-duty semantic analysis on the file contents. +It is, however, possible to obtain satisfactory results by employing +various heuristics. + +Previous versions of PKZip and other zip-compatible compression tools +were using a crude detection scheme: if more than 80% (4/5) of the bytes +found in a certain buffer are within the range [7..127], the file is +labeled as plain text, otherwise it is labeled as binary. A prominent +limitation of this scheme is the restriction to Latin-based alphabets. +Other alphabets, like Greek, Cyrillic or Asian, make extensive use of +the bytes within the range [128..255], and texts using these alphabets +are most often misidentified by this scheme; in other words, the rate +of false negatives is sometimes too high, which means that the recall +is low. Another weakness of this scheme is a reduced precision, due to +the false positives that may occur when binary files containing large +amounts of textual characters are misidentified as plain text. + +In this article we propose a new, simple detection scheme that features +a much increased precision and a near-100% recall. This scheme is +designed to work on ASCII, Unicode and other ASCII-derived alphabets, +and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.) +and variable-sized encodings (ISO-2022, UTF-8, etc.). Wider encodings +(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however. + + +The Algorithm +------------- + +The algorithm works by dividing the set of bytecodes [0..255] into three +categories: +- The white list of textual bytecodes: + 9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255. +- The gray list of tolerated bytecodes: + 7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC). +- The black list of undesired, non-textual bytecodes: + 0 (NUL) to 6, 14 to 31. + +If a file contains at least one byte that belongs to the white list and +no byte that belongs to the black list, then the file is categorized as +plain text; otherwise, it is categorized as binary. (The boundary case, +when the file is empty, automatically falls into the latter category.) + + +Rationale +--------- + +The idea behind this algorithm relies on two observations. + +The first observation is that, although the full range of 7-bit codes +[0..127] is properly specified by the ASCII standard, most control +characters in the range [0..31] are not used in practice. The only +widely-used, almost universally-portable control codes are 9 (TAB), +10 (LF) and 13 (CR). There are a few more control codes that are +recognized on a reduced range of platforms and text viewers/editors: +7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these +codes are rarely (if ever) used alone, without being accompanied by +some printable text. Even the newer, portable text formats such as +XML avoid using control characters outside the list mentioned here. + +The second observation is that most of the binary files tend to contain +control characters, especially 0 (NUL). Even though the older text +detection schemes observe the presence of non-ASCII codes from the range +[128..255], the precision rarely has to suffer if this upper range is +labeled as textual, because the files that are genuinely binary tend to +contain both control characters and codes from the upper range. On the +other hand, the upper range needs to be labeled as textual, because it +is used by virtually all ASCII extensions. In particular, this range is +used for encoding non-Latin scripts. + +Since there is no counting involved, other than simply observing the +presence or the absence of some byte values, the algorithm produces +consistent results, regardless what alphabet encoding is being used. +(If counting were involved, it could be possible to obtain different +results on a text encoded, say, using ISO-8859-16 versus UTF-8.) + +There is an extra category of plain text files that are "polluted" with +one or more black-listed codes, either by mistake or by peculiar design +considerations. In such cases, a scheme that tolerates a small fraction +of black-listed codes would provide an increased recall (i.e. more true +positives).

Only complete Huffman codes are counted. + + Two codes are considered distinct if the vectors of the number of codes per + length are not identical. So permutations of the symbol assignments result + in the same code for the counting, as do permutations of the assignments of + the bit values to the codes (i.e. only canonical codes are counted). + + We build a code from shorter to longer lengths, determining how many symbols + are coded at each length. At each step, we have how many symbols remain to + be coded, what the last code length used was, and how many bit patterns of + that length remain unused. Then we add one to the code length and double the + number of unused patterns to graduate to the next code length. We then + assign all portions of the remaining symbols to that code length that + preserve the properties of a correct and eventually complete code. Those + properties are: we cannot use more bit patterns than are available; and when + all the symbols are used, there are exactly zero possible bit patterns + remaining. + + The inflate Huffman decoding algorithm uses two-level lookup tables for + speed. There is a single first-level table to decode codes up to root bits + in length (root == 9 in the current inflate implementation). The table + has 1 << root entries and is indexed by the next root bits of input. Codes + shorter than root bits have replicated table entries, so that the correct + entry is pointed to regardless of the bits that follow the short code. If + the code is longer than root bits, then the table entry points to a second- + level table. The size of that table is determined by the longest code with + that root-bit prefix. If that longest code has length len, then the table + has size 1 << (len - root), to index the remaining bits in that set of + codes. Each subsequent root-bit prefix then has its own sub-table. The + total number of table entries required by the code is calculated + incrementally as the number of codes at each bit length is populated. When + all of the codes are shorter than root bits, then root is reduced to the + longest code length, resulting in a single, smaller, one-level table. + + The inflate algorithm also provides for small values of root (relative to + the log2 of the number of symbols), where the shortest code has more bits + than root. In that case, root is increased to the length of the shortest + code. This program, by design, does not handle that case, so it is verified + that the number of symbols is less than 2^(root + 1). + + In order to speed up the examination (by about ten orders of magnitude for + the default arguments), the intermediate states in the build-up of a code + are remembered and previously visited branches are pruned. The memory + required for this will increase rapidly with the total number of symbols and + the maximum code length in bits. However this is a very small price to pay + for the vast speedup. + + First, all of the possible Huffman codes are counted, and reachable + intermediate states are noted by a non-zero count in a saved-results array. + Second, the intermediate states that lead to (root + 1) bit or longer codes + are used to look at all sub-codes from those junctures for their inflate + memory usage. (The amount of memory used is not affected by the number of + codes of root bits or less in length.) Third, the visited states in the + construction of those sub-codes and the associated calculation of the table + size is recalled in order to avoid recalculating from the same juncture. + Beginning the code examination at (root + 1) bit codes, which is enabled by + identifying the reachable nodes, accounts for about six of the orders of + magnitude of improvement for the default arguments. About another four + orders of magnitude come from not revisiting previous states. Out of + approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes + need to be examined to cover all of the possible table memory usage cases + for the default arguments of 286 symbols limited to 15-bit codes. + + Note that an unsigned long long type is used for counting. It is quite easy + to exceed the capacity of an eight-byte integer with a large number of + symbols and a large maximum code length, so multiple-precision arithmetic + would need to replace the unsigned long long arithmetic in that case. This + program will abort if an overflow occurs. The big_t type identifies where + the counting takes place. + + An unsigned long long type is also used for calculating the number of + possible codes remaining at the maximum length. This limits the maximum + code length to the number of bits in a long long minus the number of bits + needed to represent the symbols in a flat code.

The + strategy is to write the short strings in an uncompressed form to the end of + the gzip file, only compressing when the amount of uncompressed data has + reached a given threshold. + + gzlog also provides protection against interruptions in the process due to + system crashes. The status of the operation is recorded in an extra field + in the gzip file, and is only updated once the gzip file is brought to a + valid state. The last data to be appended or compressed is saved in an + auxiliary file, so that if the operation is interrupted, it can be completed + the next time an append operation is attempted. + + gzlog maintains another auxiliary file with the last 32K of data from the + compressed portion, which is preloaded for the compression of the subsequent + data. This minimizes the impact to the compression ratio of appending. + */ + +/* + Operations Concept: + + Files (log name "foo"): + foo.gz -- gzip file with the complete log + foo.add -- last message to append or last data to compress + foo.dict -- dictionary of the last 32K of data for next compression + foo.temp -- temporary dictionary file for compression after this one + foo.lock -- lock file for reading and writing the other files + foo.repairs -- log file for log file recovery operations (not compressed) + + gzip file structure: + - fixed-length (no file name) header with extra field (see below) + - compressed data ending initially with empty stored block + - uncompressed data filling out originally empty stored block and + subsequent stored blocks as needed (16K max each) + - gzip trailer + - no junk at end (no other gzip streams) + + When appending data, the information in the first three items above plus the + foo.add file are sufficient to recover an interrupted append operation. The + extra field has the necessary information to restore the start of the last + stored block and determine where to append the data in the foo.add file, as + well as the crc and length of the gzip data before the append operation. + + The foo.add file is created before the gzip file is marked for append, and + deleted after the gzip file is marked as complete. So if the append + operation is interrupted, the data to add will still be there. If due to + some external force, the foo.add file gets deleted between when the append + operation was interrupted and when recovery is attempted, the gzip file will + still be restored, but without the appended data. + + When compressing data, the information in the first two items above plus the + foo.add file are sufficient to recover an interrupted compress operation. + The extra field has the necessary information to find the end of the + compressed data, and contains both the crc and length of just the compressed + data and of the complete set of data including the contents of the foo.add + file. + + Again, the foo.add file is maintained during the compress operation in case + of an interruption. If in the unlikely event the foo.add file with the data + to be compressed is missing due to some external force, a gzip file with + just the previous compressed data will be reconstructed. In this case, all + of the data that was to be compressed is lost (approximately one megabyte). + This will not occur if all that happened was an interruption of the compress + operation. + + The third state that is marked is the replacement of the old dictionary with + the new dictionary after a compress operation. Once compression is + complete, the gzip file is marked as being in the replace state. This + completes the gzip file, so an interrupt after being so marked does not + result in recompression. Then the dictionary file is replaced, and the gzip + file is marked as completed. This state prevents the possibility of + restarting compression with the wrong dictionary file. + + All three operations are wrapped by a lock/unlock procedure. In order to + gain exclusive access to the log files, first a foo.lock file must be + exclusively created. When all operations are complete, the lock is + released by deleting the foo.lock file. If when attempting to create the + lock file, it already exists and the modify time of the lock file is more + than five minutes old (set by the PATIENCE define below), then the old + lock file is considered stale and deleted, and the exclusive creation of + the lock file is retried. To assure that there are no false assessments + of the staleness of the lock file, the operations periodically touch the + lock file to update the modified date. + + Following is the definition of the extra field with all of the information + required to enable the above append and compress operations and their + recovery if interrupted. Multi-byte values are stored little endian + (consistent with the gzip format). File pointers are eight bytes long. + The crc's and lengths for the gzip trailer are four bytes long. (Note that + the length at the end of a gzip file is used for error checking only, and + for large files is actually the length modulo 2^32.) The stored block + length is two bytes long. The gzip extra field two-byte identification is + "ap" for append. It is assumed that writing the extra field to the file is + an "atomic" operation. That is, either all of the extra field is written + to the file, or none of it is, if the operation is interrupted right at the + point of updating the extra field. This is a reasonable assumption, since + the extra field is within the first 52 bytes of the file, which is smaller + than any expected block size for a mass storage device (usually 512 bytes or + larger). + + Extra field (35 bytes): + - Pointer to first stored block length -- this points to the two-byte length + of the first stored block, which is followed by the two-byte, one's + complement of that length. The stored block length is preceded by the + three-bit header of the stored block, which is the actual start of the + stored block in the deflate format. See the bit offset field below. + - Pointer to the last stored block length. This is the same as above, but + for the last stored block of the uncompressed data in the gzip file. + Initially this is the same as the first stored block length pointer. + When the stored block gets to 16K (see the MAX_STORE define), then a new + stored block as added, at which point the last stored block length pointer + is different from the first stored block length pointer. When they are + different, the first bit of the last stored block header is eight bits, or + one byte back from the block length. + - Compressed data crc and length. This is the crc and length of the data + that is in the compressed portion of the deflate stream. These are used + only in the event that the foo.add file containing the data to compress is + lost after a compress operation is interrupted. + - Total data crc and length. This is the crc and length of all of the data + stored in the gzip file, compressed and uncompressed. It is used to + reconstruct the gzip trailer when compressing, as well as when recovering + interrupted operations. + - Final stored block length. This is used to quickly find where to append, + and allows the restoration of the original final stored block state when + an append operation is interrupted. + - First stored block start as the number of bits back from the final stored + block first length byte. This value is in the range of 3..10, and is + stored as the low three bits of the final byte of the extra field after + subtracting three (0..7). This allows the last-block bit of the stored + block header to be updated when a new stored block is added, for the case + when the first stored block and the last stored block are the same. (When + they are different, the numbers of bits back is known to be eight.) This + also allows for new compressed data to be appended to the old compressed + data in the compress operation, overwriting the previous first stored + block, or for the compressed data to be terminated and a valid gzip file + reconstructed on the off chance that a compression operation was + interrupted and the data to compress in the foo.add file was deleted. + - The operation in process. This is the next two bits in the last byte (the + bits under the mask 0x18). The are interpreted as 0: nothing in process, + 1: append in process, 2: compress in process, 3: replace in process. + - The top three bits of the last byte in the extra field are reserved and + are currently set to zero. + + Main procedure: + - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of + the system open() call. If the modify time of an existing lock file is + more than PATIENCE seconds old, then the lock file is deleted and the + exclusive create is retried. + - Load the extra field from the foo.gz file, and see if an operation was in + progress but not completed. If so, apply the recovery procedure below. + - Perform the append procedure with the provided data. + - If the uncompressed data in the foo.gz file is 1MB or more, apply the + compress procedure. + - Delete the foo.lock file. + + Append procedure: + - Put what to append in the foo.add file so that the operation can be + restarted if this procedure is interrupted. + - Mark the foo.gz extra field with the append operation in progress. + + Restore the original last-block bit and stored block length of the last + stored block from the information in the extra field, in case a previous + append operation was interrupted. + - Append the provided data to the last stored block, creating new stored + blocks as needed and updating the stored blocks last-block bits and + lengths. + - Update the crc and length with the new data, and write the gzip trailer. + - Write over the extra field (with a single write operation) with the new + pointers, lengths, and crc's, and mark the gzip file as not in process. + Though there is still a foo.add file, it will be ignored since nothing + is in process. If a foo.add file is leftover from a previously + completed operation, it is truncated when writing new data to it. + - Delete the foo.add file. + + Compress and replace procedures: + - Read all of the uncompressed data in the stored blocks in foo.gz and write + it to foo.add. Also write foo.temp with the last 32K of that data to + provide a dictionary for the next invocation of this procedure. + - Rewrite the extra field marking foo.gz with a compression in process. + * If there is no data provided to compress (due to a missing foo.add file + when recovering), reconstruct and truncate the foo.gz file to contain + only the previous compressed data and proceed to the step after the next + one. Otherwise ... + - Compress the data with the dictionary in foo.dict, and write to the + foo.gz file starting at the bit immediately following the last previously + compressed block. If there is no foo.dict, proceed anyway with the + compression at slightly reduced efficiency. (For the foo.dict file to be + missing requires some external failure beyond simply the interruption of + a compress operation.) During this process, the foo.lock file is + periodically touched to assure that that file is not considered stale by + another process before we're done. The deflation is terminated with a + non-last empty static block (10 bits long), that is then located and + written over by a last-bit-set empty stored block. + - Append the crc and length of the data in the gzip file (previously + calculated during the append operations). + - Write over the extra field with the updated stored block offsets, bits + back, crc's, and lengths, and mark foo.gz as in process for a replacement + of the dictionary. + @ Delete the foo.add file. + - Replace foo.dict with foo.temp. + - Write over the extra field, marking foo.gz as complete. + + Recovery procedure: + - If not a replace recovery, read in the foo.add file, and provide that data + to the appropriate recovery below. If there is no foo.add file, provide + a zero data length to the recovery. In that case, the append recovery + restores the foo.gz to the previous compressed + uncompressed data state. + For the the compress recovery, a missing foo.add file results in foo.gz + being restored to the previous compressed-only data state. + - Append recovery: + - Pick up append at + step above + - Compress recovery: + - Pick up compress at * step above + - Replace recovery: + - Pick up compress at @ step above + - Log the repair with a date stamp in foo.repairs + */ + +#include +#include /* rename, fopen, fprintf, fclose */ +#include /* malloc, free */ +#include /* strlen, strrchr, strcpy, strncpy, strcmp */ +#include /* open */ +#include /* lseek, read, write, close, unlink, sleep, */ + /* ftruncate, fsync */ +#include /* errno */ +#include /* time, ctime */ +#include /* stat */ +#include /* utimes */ +#include "zlib.h" /* crc32 */ + +#include "gzlog.h" /* header for external access */ -#include "gzlog.h" /* interface */ #define local static +typedef unsigned int uint;

Introduction

- The 'zlib' compression library provides in-memory compression and - decompression functions, including integrity checks of the uncompressed - data. This version of the library supports only one compression method - (deflation) but other algorithms will be added later and will have the same - stream interface. -

- - Compression can be done in a single step if the buffers are large - enough (for example if an input file is mmap'ed), or can be done by - repeated calls of the compression function. In the latter case, the - application must provide more input and/or consume the output - (providing more output space) before each call. -

- - The library also supports reading and writing files in gzip (.gz) format - with an interface similar to that of stdio. -

- - The library does not install any signal handler. The decoder checks - the consistency of the compressed data, so the library should never - crash even in case of corrupted input. -

- -

-

Utility functions

- The following utility functions are implemented on top of the - basic stream-oriented functions. - To simplify the interface, some - default options are assumed (compression level and memory usage, - standard memory allocation functions). The source code of these - utility functions can easily be modified if you need special options. -

Function description

-
-
int compress (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); -
- Compresses the source buffer into the destination buffer. sourceLen is - the byte length of the source buffer. Upon entry, destLen is the total - size of the destination buffer, which must be at least 0.1% larger than - sourceLen plus 12 bytes. Upon exit, destLen is the actual size of the - compressed buffer.

- This function can be used to compress a whole file at once if the - input file is mmap'ed.

- compress returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if there was not enough room in the output - buffer.

- -

int compress2 (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen, int level); -
- Compresses the source buffer into the destination buffer. The level - parameter has the same meaning as in deflateInit. sourceLen is the byte - length of the source buffer. Upon entry, destLen is the total size of the - destination buffer, which must be at least 0.1% larger than sourceLen plus - 12 bytes. Upon exit, destLen is the actual size of the compressed buffer. -

- - compress2 returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_BUF_ERROR if there was not enough room in the output buffer, - Z_STREAM_ERROR if the level parameter is invalid. -

- -

int uncompress (Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen); -
- Decompresses the source buffer into the destination buffer. sourceLen is - the byte length of the source buffer. Upon entry, destLen is the total - size of the destination buffer, which must be large enough to hold the - entire uncompressed data. (The size of the uncompressed data must have - been saved previously by the compressor and transmitted to the decompressor - by some mechanism outside the scope of this compression library.) - Upon exit, destLen is the actual size of the compressed buffer.

- This function can be used to decompress a whole file at once if the - input file is mmap'ed. -

- - uncompress returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if there was not enough room in the output - buffer, or Z_DATA_ERROR if the input data was corrupted. -

- -

typedef voidp gzFile; -

- -

gzFile gzopen (const char *path, const char *mode); -
- Opens a gzip (.gz) file for reading or writing. The mode parameter - is as in fopen ("rb" or "wb") but can also include a compression level - ("wb9") or a strategy: 'f' for filtered data as in "wb6f", 'h' for - Huffman only compression as in "wb1h". (See the description - of deflateInit2 for more information about the strategy parameter.) -

- - gzopen can be used to read a file which is not in gzip format ; in this - case gzread will directly read from the file without decompression. -

- - gzopen returns NULL if the file could not be opened or if there was - insufficient memory to allocate the (de)compression state ; errno - can be checked to distinguish the two cases (if errno is zero, the - zlib error is Z_MEM_ERROR). -

- -

gzFile gzdopen (int fd, const char *mode); -
- gzdopen() associates a gzFile with the file descriptor fd. File - descriptors are obtained from calls like open, dup, creat, pipe or - fileno (in the file has been previously opened with fopen). - The mode parameter is as in gzopen. -

- The next call of gzclose on the returned gzFile will also close the - file descriptor fd, just like fclose(fdopen(fd), mode) closes the file - descriptor fd. If you want to keep fd open, use gzdopen(dup(fd), mode). -

- gzdopen returns NULL if there was insufficient memory to allocate - the (de)compression state. -

- -

int gzsetparams (gzFile file, int level, int strategy); -
- Dynamically update the compression level or strategy. See the description - of deflateInit2 for the meaning of these parameters. -

- gzsetparams returns Z_OK if success, or Z_STREAM_ERROR if the file was not - opened for writing. -

- -

int gzread (gzFile file, voidp buf, unsigned len); -
- Reads the given number of uncompressed bytes from the compressed file. - If the input file was not in gzip format, gzread copies the given number - of bytes into the buffer. -

- gzread returns the number of uncompressed bytes actually read (0 for - end of file, -1 for error). -

- -

int gzwrite (gzFile file, const voidp buf, unsigned len); -
- Writes the given number of uncompressed bytes into the compressed file. - gzwrite returns the number of uncompressed bytes actually written - (0 in case of error). -

- -

int VA gzprintf (gzFile file, const char *format, ...); -
- Converts, formats, and writes the args to the compressed file under - control of the format string, as in fprintf. gzprintf returns the number of - uncompressed bytes actually written (0 in case of error). -

- -

int gzputs (gzFile file, const char *s); -
- Writes the given null-terminated string to the compressed file, excluding - the terminating null character. -

- gzputs returns the number of characters written, or -1 in case of error. -

- -

char * gzgets (gzFile file, char *buf, int len); -
- Reads bytes from the compressed file until len-1 characters are read, or - a newline character is read and transferred to buf, or an end-of-file - condition is encountered. The string is then terminated with a null - character. -

- gzgets returns buf, or Z_NULL in case of error. -

- -

int gzputc (gzFile file, int c); -
- Writes c, converted to an unsigned char, into the compressed file. - gzputc returns the value that was written, or -1 in case of error. -

- -

int gzgetc (gzFile file); -
- Reads one byte from the compressed file. gzgetc returns this byte - or -1 in case of end of file or error. -

- -

int gzflush (gzFile file, int flush); -
- Flushes all pending output into the compressed file. The parameter - flush is as in the deflate() function. The return value is the zlib - error number (see function gzerror below). gzflush returns Z_OK if - the flush parameter is Z_FINISH and all output could be flushed. -

- gzflush should be called only when strictly necessary because it can - degrade compression. -

- -

z_off_t gzseek (gzFile file, z_off_t offset, int whence); -
- Sets the starting position for the next gzread or gzwrite on the - given compressed file. The offset represents a number of bytes in the - uncompressed data stream. The whence parameter is defined as in lseek(2); - the value SEEK_END is not supported. -

- If the file is opened for reading, this function is emulated but can be - extremely slow. If the file is opened for writing, only forward seeks are - supported ; gzseek then compresses a sequence of zeroes up to the new - starting position. -

- gzseek returns the resulting offset location as measured in bytes from - the beginning of the uncompressed stream, or -1 in case of error, in - particular if the file is opened for writing and the new starting position - would be before the current position. -

- -

int gzrewind (gzFile file); -
- Rewinds the given file. This function is supported only for reading. -

- gzrewind(file) is equivalent to (int)gzseek(file, 0L, SEEK_SET) -

- -

z_off_t gztell (gzFile file); -
- Returns the starting position for the next gzread or gzwrite on the - given compressed file. This position represents a number of bytes in the - uncompressed data stream. -

- - gztell(file) is equivalent to gzseek(file, 0L, SEEK_CUR) -

- -

int gzeof (gzFile file); -
- Returns 1 when EOF has previously been detected reading the given - input stream, otherwise zero. -

- -

int gzclose (gzFile file); -
- Flushes all pending output if necessary, closes the compressed file - and deallocates all the (de)compression state. The return value is the zlib - error number (see function gzerror below). -

- -

const char * gzerror (gzFile file, int *errnum); -
- Returns the error message for the last error which occurred on the - given compressed file. errnum is set to zlib error number. If an - error occurred in the file system and not in the compression library, - errnum is set to Z_ERRNO and the application may consult errno - to get the exact error code. -

Basic functions

-

Function list

Function description

-
-
const char * zlibVersion (void); -
The application can compare zlibVersion and ZLIB_VERSION for consistency. - If the first character differs, the library code actually used is - not compatible with the zlib.h header file used by the application. - This check is automatically made by deflateInit and inflateInit. -

- -

int deflateInit (z_streamp strm, int level); -
- Initializes the internal stream state for compression. The fields - zalloc, zfree and opaque must be initialized before by the caller. - If zalloc and zfree are set to Z_NULL, deflateInit updates them to - use default allocation functions. -

- - The compression level must be Z_DEFAULT_COMPRESSION, or between 0 and 9: - 1 gives best speed, 9 gives best compression, 0 gives no compression at - all (the input data is simply copied a block at a time). -

- - Z_DEFAULT_COMPRESSION requests a default compromise between speed and - compression (currently equivalent to level 6). -

- - deflateInit returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_STREAM_ERROR if level is not a valid compression level, - Z_VERSION_ERROR if the zlib library version (zlib_version) is incompatible - with the version assumed by the caller (ZLIB_VERSION). - msg is set to null if there is no error message. deflateInit does not - perform any compression: this will be done by deflate(). -

- -

int deflate (z_streamp strm, int flush); -
- deflate compresses as much data as possible, and stops when the input - buffer becomes empty or the output buffer becomes full. It may introduce some - output latency (reading input without producing any output) except when - forced to flush.

- - The detailed semantics are as follows. deflate performs one or both of the - following actions: - -

    -
  • Compress more input starting at next_in and update next_in and avail_in - accordingly. If not all input can be processed (because there is not - enough room in the output buffer), next_in and avail_in are updated and - processing will resume at this point for the next call of deflate(). - -
  • - Provide more output starting at next_out and update next_out and avail_out - accordingly. This action is forced if the parameter flush is non zero. - Forcing flush frequently degrades the compression ratio, so this parameter - should be set only when necessary (in interactive applications). - Some output may be provided even if flush is not set. -

- - Before the call of deflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming - more output, and updating avail_in or avail_out accordingly ; avail_out - should never be zero before the call. The application can consume the - compressed output when it wants, for example when the output buffer is full - (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK - and with zero avail_out, it must be called again after making room in the - output buffer because there might be more output pending. -

- - If the parameter flush is set to Z_SYNC_FLUSH, all pending output is - flushed to the output buffer and the output is aligned on a byte boundary, so - that the decompressor can get all input data available so far. (In particular - avail_in is zero after the call if enough output space has been provided - before the call.) Flushing may degrade compression for some compression - algorithms and so it should be used only when necessary. -

- - If flush is set to Z_FULL_FLUSH, all output is flushed as with - Z_SYNC_FLUSH, and the compression state is reset so that decompression can - restart from this point if previous compressed data has been damaged or if - random access is desired. Using Z_FULL_FLUSH too often can seriously degrade - the compression. -

- - If deflate returns with avail_out == 0, this function must be called again - with the same value of the flush parameter and more output space (updated - avail_out), until the flush is complete (deflate returns with non-zero - avail_out). -

- - If the parameter flush is set to Z_FINISH, pending input is processed, - pending output is flushed and deflate returns with Z_STREAM_END if there - was enough output space ; if deflate returns with Z_OK, this function must be - called again with Z_FINISH and more output space (updated avail_out) but no - more input data, until it returns with Z_STREAM_END or an error. After - deflate has returned Z_STREAM_END, the only possible operations on the - stream are deflateReset or deflateEnd. -

- - Z_FINISH can be used immediately after deflateInit if all the compression - is to be done in a single step. In this case, avail_out must be at least - 0.1% larger than avail_in plus 12 bytes. If deflate does not return - Z_STREAM_END, then it must be called again as described above. -

- - deflate() sets strm-> adler to the adler32 checksum of all input read - so far (that is, total_in bytes). -

- - deflate() may update data_type if it can make a good guess about - the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered - binary. This field is only for information purposes and does not affect - the compression algorithm in any manner. -

- - deflate() returns Z_OK if some progress has been made (more input - processed or more output produced), Z_STREAM_END if all input has been - consumed and all output has been produced (only when flush is set to - Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example - if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible - (for example avail_in or avail_out was zero). -

- -

int deflateEnd (z_streamp strm); -
- All dynamically allocated data structures for this stream are freed. - This function discards any unprocessed input and does not flush any - pending output. -

- - deflateEnd returns Z_OK if success, Z_STREAM_ERROR if the - stream state was inconsistent, Z_DATA_ERROR if the stream was freed - prematurely (some input or output was discarded). In the error case, - msg may be set but then points to a static string (which must not be - deallocated). -

- -

int inflateInit (z_streamp strm); -
- Initializes the internal stream state for decompression. The fields - next_in, avail_in, zalloc, zfree and opaque must be initialized before by - the caller. If next_in is not Z_NULL and avail_in is large enough (the exact - value depends on the compression method), inflateInit determines the - compression method from the zlib header and allocates all data structures - accordingly ; otherwise the allocation will be deferred to the first call of - inflate. If zalloc and zfree are set to Z_NULL, inflateInit updates them to - use default allocation functions. -

- - inflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_VERSION_ERROR if the zlib library version is incompatible with the - version assumed by the caller. msg is set to null if there is no error - message. inflateInit does not perform any decompression apart from reading - the zlib header if present: this will be done by inflate(). (So next_in and - avail_in may be modified, but next_out and avail_out are unchanged.) -

- -

int inflate (z_streamp strm, int flush); -
- inflate decompresses as much data as possible, and stops when the input - buffer becomes empty or the output buffer becomes full. It may some - introduce some output latency (reading input without producing any output) - except when forced to flush. -

- - The detailed semantics are as follows. inflate performs one or both of the - following actions: - -

    -
  • Decompress more input starting at next_in and update next_in and avail_in - accordingly. If not all input can be processed (because there is not - enough room in the output buffer), next_in is updated and processing - will resume at this point for the next call of inflate(). - -
  • Provide more output starting at next_out and update next_out and - avail_out accordingly. inflate() provides as much output as possible, - until there is no more input data or no more space in the output buffer - (see below about the flush parameter). -

- - Before the call of inflate(), the application should ensure that at least - one of the actions is possible, by providing more input and/or consuming - more output, and updating the next_* and avail_* values accordingly. - The application can consume the uncompressed output when it wants, for - example when the output buffer is full (avail_out == 0), or after each - call of inflate(). If inflate returns Z_OK and with zero avail_out, it - must be called again after making room in the output buffer because there - might be more output pending. -

- - If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much - output as possible to the output buffer. The flushing behavior of inflate is - not specified for values of the flush parameter other than Z_SYNC_FLUSH - and Z_FINISH, but the current implementation actually flushes as much output - as possible anyway. -

- - inflate() should normally be called until it returns Z_STREAM_END or an - error. However if all decompression is to be performed in a single step - (a single call of inflate), the parameter flush should be set to - Z_FINISH. In this case all pending input is processed and all pending - output is flushed ; avail_out must be large enough to hold all the - uncompressed data. (The size of the uncompressed data may have been saved - by the compressor for this purpose.) The next operation on this stream must - be inflateEnd to deallocate the decompression state. The use of Z_FINISH - is never required, but can be used to inform inflate that a faster routine - may be used for the single inflate() call. -

- - If a preset dictionary is needed at this point (see inflateSetDictionary - below), inflate sets strm-adler to the adler32 checksum of the - dictionary chosen by the compressor and returns Z_NEED_DICT ; otherwise - it sets strm-> adler to the adler32 checksum of all output produced - so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or - an error code as described below. At the end of the stream, inflate() - checks that its computed adler32 checksum is equal to that saved by the - compressor and returns Z_STREAM_END only if the checksum is correct. -

- - inflate() returns Z_OK if some progress has been made (more input processed - or more output produced), Z_STREAM_END if the end of the compressed data has - been reached and all uncompressed output has been produced, Z_NEED_DICT if a - preset dictionary is needed at this point, Z_DATA_ERROR if the input data was - corrupted (input stream not conforming to the zlib format or incorrect - adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent - (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not - enough memory, Z_BUF_ERROR if no progress is possible or if there was not - enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR - case, the application may then call inflateSync to look for a good - compression block. -

- -

int inflateEnd (z_streamp strm); -
- All dynamically allocated data structures for this stream are freed. - This function discards any unprocessed input and does not flush any - pending output. -

- - inflateEnd returns Z_OK if success, Z_STREAM_ERROR if the stream state - was inconsistent. In the error case, msg may be set but then points to a - static string (which must not be deallocated). -

Function list

Function description

-
-
int deflateInit2 (z_streamp strm, int level, int method, int windowBits, int memLevel, int strategy); - -
This is another version of deflateInit with more compression options. The - fields next_in, zalloc, zfree and opaque must be initialized before by - the caller.

- - The method parameter is the compression method. It must be Z_DEFLATED in - this version of the library.

- - The windowBits parameter is the base two logarithm of the window size - (the size of the history buffer). It should be in the range 8..15 for this - version of the library. Larger values of this parameter result in better - compression at the expense of memory usage. The default value is 15 if - deflateInit is used instead.

- - The memLevel parameter specifies how much memory should be allocated - for the internal compression state. memLevel=1 uses minimum memory but - is slow and reduces compression ratio ; memLevel=9 uses maximum memory - for optimal speed. The default value is 8. See zconf.h for total memory - usage as a function of windowBits and memLevel.

- - The strategy parameter is used to tune the compression algorithm. Use the - value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a - filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no - string match). Filtered data consists mostly of small values with a - somewhat random distribution. In this case, the compression algorithm is - tuned to compress them better. The effect of Z_FILTERED is to force more - Huffman coding and less string matching ; it is somewhat intermediate - between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects - the compression ratio but not the correctness of the compressed output even - if it is not set appropriately.

- - deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid - method). msg is set to null if there is no error message. deflateInit2 does - not perform any compression: this will be done by deflate().

- -

int deflateSetDictionary (z_streamp strm, const Bytef *dictionary, uInt dictLength); -
- Initializes the compression dictionary from the given byte sequence - without producing any compressed output. This function must be called - immediately after deflateInit, deflateInit2 or deflateReset, before any - call of deflate. The compressor and decompressor must use exactly the same - dictionary (see inflateSetDictionary).

- - The dictionary should consist of strings (byte sequences) that are likely - to be encountered later in the data to be compressed, with the most commonly - used strings preferably put towards the end of the dictionary. Using a - dictionary is most useful when the data to be compressed is short and can be - predicted with good accuracy ; the data can then be compressed better than - with the default empty dictionary.

- - Depending on the size of the compression data structures selected by - deflateInit or deflateInit2, a part of the dictionary may in effect be - discarded, for example if the dictionary is larger than the window size in - deflate or deflate2. Thus the strings most likely to be useful should be - put at the end of the dictionary, not at the front.

- - Upon return of this function, strm-> adler is set to the Adler32 value - of the dictionary ; the decompressor may later use this value to determine - which dictionary has been used by the compressor. (The Adler32 value - applies to the whole dictionary even if only a subset of the dictionary is - actually used by the compressor.)

- - deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a - parameter is invalid (such as NULL dictionary) or the stream state is - inconsistent (for example if deflate has already been called for this stream - or if the compression method is bsort). deflateSetDictionary does not - perform any compression: this will be done by deflate().

- -

int deflateCopy (z_streamp dest, z_streamp source); -
- Sets the destination stream as a complete copy of the source stream.

- - This function can be useful when several compression strategies will be - tried, for example when there are several ways of pre-processing the input - data with a filter. The streams that will be discarded should then be freed - by calling deflateEnd. Note that deflateCopy duplicates the internal - compression state which can be quite large, so this strategy is slow and - can consume lots of memory.

- - deflateCopy returns Z_OK if success, Z_MEM_ERROR if there was not - enough memory, Z_STREAM_ERROR if the source stream state was inconsistent - (such as zalloc being NULL). msg is left unchanged in both source and - destination.

- -

int deflateReset (z_streamp strm); -
This function is equivalent to deflateEnd followed by deflateInit, - but does not free and reallocate all the internal compression state. - The stream will keep the same compression level and any other attributes - that may have been set by deflateInit2.

- - deflateReset returns Z_OK if success, or Z_STREAM_ERROR if the source - stream state was inconsistent (such as zalloc or state being NULL).

- -

int deflateParams (z_streamp strm, int level, int strategy); -
- Dynamically update the compression level and compression strategy. The - interpretation of level and strategy is as in deflateInit2. This can be - used to switch between compression and straight copy of the input data, or - to switch to a different kind of input data requiring a different - strategy. If the compression level is changed, the input available so far - is compressed with the old level (and may be flushed); the new level will - take effect only at the next call of deflate().

- - Before the call of deflateParams, the stream state must be set as for - a call of deflate(), since the currently available input may have to - be compressed and flushed. In particular, strm-> avail_out must be - non-zero.

- - deflateParams returns Z_OK if success, Z_STREAM_ERROR if the source - stream state was inconsistent or if a parameter was invalid, Z_BUF_ERROR - if strm->avail_out was zero.

- -

int inflateInit2 (z_streamp strm, int windowBits); - -
This is another version of inflateInit with an extra parameter. The - fields next_in, avail_in, zalloc, zfree and opaque must be initialized - before by the caller.

- - The windowBits parameter is the base two logarithm of the maximum window - size (the size of the history buffer). It should be in the range 8..15 for - this version of the library. The default value is 15 if inflateInit is used - instead. If a compressed stream with a larger window size is given as - input, inflate() will return with the error code Z_DATA_ERROR instead of - trying to allocate a larger window.

- - inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough - memory, Z_STREAM_ERROR if a parameter is invalid (such as a negative - memLevel). msg is set to null if there is no error message. inflateInit2 - does not perform any decompression apart from reading the zlib header if - present: this will be done by inflate(). (So next_in and avail_in may be - modified, but next_out and avail_out are unchanged.)

- -

int inflateSetDictionary (z_streamp strm, const Bytef *dictionary, uInt dictLength); -
- Initializes the decompression dictionary from the given uncompressed byte - sequence. This function must be called immediately after a call of inflate - if this call returned Z_NEED_DICT. The dictionary chosen by the compressor - can be determined from the Adler32 value returned by this call of - inflate. The compressor and decompressor must use exactly the same - dictionary (see deflateSetDictionary).

- - inflateSetDictionary returns Z_OK if success, Z_STREAM_ERROR if a - parameter is invalid (such as NULL dictionary) or the stream state is - inconsistent, Z_DATA_ERROR if the given dictionary doesn't match the - expected one (incorrect Adler32 value). inflateSetDictionary does not - perform any decompression: this will be done by subsequent calls of - inflate().

- -

int inflateSync (z_streamp strm); - -
Skips invalid compressed data until a full flush point (see above the - description of deflate with Z_FULL_FLUSH) can be found, or until all - available input is skipped. No output is provided.

- - inflateSync returns Z_OK if a full flush point has been found, Z_BUF_ERROR - if no more input was provided, Z_DATA_ERROR if no flush point has been found, - or Z_STREAM_ERROR if the stream structure was inconsistent. In the success - case, the application may save the current current value of total_in which - indicates where valid compressed data was found. In the error case, the - application may repeatedly call inflateSync, providing more input each time, - until success or end of the input data.

- -

int inflateReset (z_streamp strm); -
- This function is equivalent to inflateEnd followed by inflateInit, - but does not free and reallocate all the internal decompression state. - The stream will keep attributes that may have been set by inflateInit2. -

- - inflateReset returns Z_OK if success, or Z_STREAM_ERROR if the source - stream state was inconsistent (such as zalloc or state being NULL). -

Checksum functions

- These functions are not related to compression but are exported - anyway because they might be useful in applications using the - compression library. -

Function list

- -

Function description

-
-
uLong adler32 (uLong adler, const Bytef *buf, uInt len); -
- Update a running Adler-32 checksum with the bytes buf[0..len-1] and - return the updated checksum. If buf is NULL, this function returns - the required initial value for the checksum. -

- An Adler-32 checksum is almost as reliable as a CRC32 but can be computed - much faster. Usage example: - 

-
-     uLong adler = adler32(0L, Z_NULL, 0);
-
-     while (read_buffer(buffer, length) != EOF) {
-       adler = adler32(adler, buffer, length);
-     }
-     if (adler != original_adler) error();
-
- -
uLong crc32 (uLong crc, const Bytef *buf, uInt len); -
- Update a running crc with the bytes buf[0..len-1] and return the updated - crc. If buf is NULL, this function returns the required initial value - for the crc. Pre- and post-conditioning (one's complement) is performed - within this function so it shouldn't be done by the application. - Usage example: - 
-
-     uLong crc = crc32(0L, Z_NULL, 0);
-
-     while (read_buffer(buffer, length) != EOF) {
-       crc = crc32(crc, buffer, length);
-     }
-     if (crc != original_crc) error();

struct z_stream_s

- - -
-typedef struct z_stream_s {
-    Bytef    *next_in;  /* next input byte */
-    uInt     avail_in;  /* number of bytes available at next_in */
-    uLong    total_in;  /* total nb of input bytes read so far */
-
-    Bytef    *next_out; /* next output byte should be put there */
-    uInt     avail_out; /* remaining free space at next_out */
-    uLong    total_out; /* total nb of bytes output so far */

-    uLong   reserved;   /* reserved for future use */
-} z_stream ;
-
-typedef z_stream FAR * z_streamp;  ÿ
-
- - The application must update next_in and avail_in when avail_in has - dropped to zero. It must update next_out and avail_out when avail_out - has dropped to zero. The application must initialize zalloc, zfree and - opaque before calling the init function. All other fields are set by the - compression library and must not be updated by the application.

- - The opaque value provided by the application will be passed as the first - parameter for calls of zalloc and zfree. This can be useful for custom - memory management. The compression library attaches no meaning to the - opaque value.

- - zalloc must return Z_NULL if there is not enough memory for the object. - If zlib is used in a multi-threaded application, zalloc and zfree must be - thread safe.

- - On 16-bit systems, the functions zalloc and zfree must be able to allocate - exactly 65536 bytes, but will not be required to allocate more than this - if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, - pointers returned by zalloc for objects of exactly 65536 bytes *must* - have their offset normalized to zero. The default allocation function - provided by this library ensures this (see zutil.c). To reduce memory - requirements and avoid any allocation of 64K objects, at the expense of - compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h). -

- - The fields total_in and total_out can be used for statistics or - progress reports. After compression, total_in holds the total size of - the uncompressed data and may be saved for use in the decompressor - (particularly if the decompressor wants to decompress everything in - a single step).
