* Inflate#push(data[, mode]) -> Boolean
|
|
* - data (Uint8Array|Array|ArrayBuffer|String): input data
|
|
* - mode (Number|Boolean): 0..6 for corresponding Z_NO_FLUSH..Z_TREE modes.
|
|
* See constants. Skipped or `false` means Z_NO_FLUSH, `true` meansh Z_FINISH.
|
|
*
|
|
* Sends input data to inflate pipe, generating [[Inflate#onData]] calls with
|
|
* new output chunks. Returns `true` on success. The last data block must have
|
|
* mode Z_FINISH (or `true`). That flush internal pending buffers and call
|
|
* [[Inflate#onEnd]].
|
|
*
|
|
* On fail call [[Inflate#onEnd]] with error code and return false.
|
|
*
|
|
* We strongly recommend to use `Uint8Array` on input for best speed (output
|
|
* format is detected automatically). Also, don't skip last param and always
|
|
* use the same type in your code (boolean or number). That will improve JS speed.
|
|
*
|
|
* For regular `Array`-s make sure all elements are [0..255].
|

* ##### Example
|
|
*
|
|
* ```javascript
|
|
* push(chunk, false); // push one of data chunks
|
|
* ...
|
|
* push(chunk, true); // push last chunk

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.

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
|
|
in the rest of the decoding tables with invalid code markers.
