inflateBack() returns.

in() and out() are called with a descriptor parameter provided in the

Decode literal, length, and distance codes and write out the resulting
|
||||
literal and match bytes until either not enough input or output is
|
||||
available, an end-of-block is encountered, or a data error is encountered.
|
||||
When large enough input and output buffers are supplied to inflate(), for
|
||||
example, a 16K input buffer and a 64K output buffer, more than 95% of the
|
||||
inflate execution time is spent in this routine.
|
||||
|
||||
Entry assumptions:
|
||||
|
||||
state->mode == LEN
|
||||
strm->avail_in >= 6
|
||||
strm->avail_out >= 258
|
||||
start >= strm->avail_out
|
||||
state->bits < 8
|
||||
|
||||
On return, state->mode is one of:
|
||||
|
||||
LEN -- ran out of enough output space or enough available input
|
||||
TYPE -- reached end of block code, inflate() to interpret next block
|
||||
BAD -- error in block data
|
||||
|
||||
Notes:
|
||||
|
||||
- The maximum input bits used by a length/distance pair is 15 bits for the
|
||||
length code, 5 bits for the length extra, 15 bits for the distance code,
|
||||
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
||||
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
||||
checking for available input while decoding.
|
||||
|
||||
- The maximum bytes that a single length/distance pair can output is 258
|
||||
bytes, which is the maximum length that can be coded. inflate_fast()
|
||||
requires strm->avail_out >= 258 for each loop to avoid checking for
|
||||
output space.

|

Process a set of code lengths to create a canonical Huffman code. The
|
||||
code lengths are lens[0..codes-1]. Each length corresponds to the
|
||||
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
||||
symbols by length from short to long, and retaining the symbol order
|
||||
for codes with equal lengths. Then the code starts with all zero bits
|
||||
for the first code of the shortest length, and the codes are integer
|
||||
increments for the same length, and zeros are appended as the length
|
||||
increases. For the deflate format, these bits are stored backwards
|
||||
from their more natural integer increment ordering, and so when the
|
||||
decoding tables are built in the large loop below, the integer codes
|
||||
are incremented backwards.
|
||||
|
||||
This routine assumes, but does not check, that all of the entries in
|
||||
lens[] are in the range 0..MAXBITS. The caller must assure this.
|
||||
1..MAXBITS is interpreted as that code length. zero means that that
|
||||
symbol does not occur in this code.
|
||||
|
||||
The codes are sorted by computing a count of codes for each length,
|
||||
creating from that a table of starting indices for each length in the
|
||||
sorted table, and then entering the symbols in order in the sorted
|
||||
table. The sorted table is work[], with that space being provided by
|
||||
the caller.
|
||||
|
||||
The length counts are used for other purposes as well, i.e. finding
|
||||
the minimum and maximum length codes, determining if there are any
|
||||
codes at all, checking for a valid set of lengths, and looking ahead
|
||||
at length counts to determine sub-table sizes when building the

decoding tables.

Create and fill in decoding tables. In this loop, the table being

with length len. That code is converted to an index by dropping drop

bits off of the bottom. For codes where len is less than drop + curr,

those top drop + curr - len bits are incremented through all values to

fill the table with replicated entries.

root is the number of index bits for the root table. When len exceeds

root, sub-tables are created pointed to by the root entry with an index

of the low root bits of huff. This is saved in low to check for when a

new sub-table should be started. drop is zero when the root table is

being filled, and drop is root when sub-tables are being filled.
|
||||
|
||||
When a new sub-table is needed, it is necessary to look ahead in the
|
||||
code lengths to determine what size sub-table is needed. The length
|
||||
counts are used for this, and so count[] is decremented as codes are
|
||||
entered in the tables.

used keeps track of how many table entries have been allocated from the

provided *table space. It is checked for LENS and DIST tables against

the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in

the initial root table size constants. See the comments in inftrees.h
|
||||
for more information.

|
||||
sym increments through all symbols, and the loop terminates when

all codes of length max, i.e. all codes, have been processed. This
|

routine permits incomplete codes, so another loop after this one fills
|
||||

|

* close to exact, as well as small, upper bound on the compressed size. This
|
||||
* is an expansion of ~0.03%, plus a small constant.
|
||||
*
|
||||
* For any setting other than those defaults for windowBits and memLevel,
|
||||
* the value returned is a conservative worst case for the maximum expansion
|
||||
* resulting from using fixed blocks instead of stored blocks, which deflate
|
||||
* can emit on compressed data for some combinations of the parameters.
|
||||
* For any setting other than those defaults for windowBits and memLevel, one
|
||||
* of two worst case bounds is returned. This is at most an expansion of ~4% or
|
||||
* ~13%, plus a small constant.
|
||||
*
|
||||
* This function could be more sophisticated to provide closer upper bounds for
|
||||
* every combination of windowBits and memLevel. But even the conservative
|
||||
* upper bound of about 14% expansion does not seem onerous for output buffer
|
||||
* allocation.
|
||||
* Both the 0.03% and 4% derive from the overhead of stored blocks. The first
|
||||
* one is for stored blocks of 16383 bytes (memLevel == 8), whereas the second
|
||||
* is for stored blocks of 127 bytes (the worst case memLevel == 1). The
|
||||
* expansion results from five bytes of header for each stored block.
|
||||
*
|
||||
* The larger expansion of 13% results from a window size less than or equal to
|
||||
* the symbols buffer size (windowBits <= memLevel + 7). In that case some of
|
||||
* the data being compressed may have slid out of the sliding window, impeding
|
||||
* a stored block from being emitted. Then the only choice is a fixed or
|
||||
* dynamic block, where a fixed block limits the maximum expansion to 9 bits
|
||||
* per 8-bit byte, plus 10 bits for every block. The smallest block size for
|
||||
* which this can occur is 255 (memLevel == 2).
|
||||
*
|
||||
* Shifts are used to approximate divisions, for speed.
