- 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
|
|
filled is at next and has curr index bits. The code being used is huff
|
|
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
|
|
in the rest of the decoding tables with invalid code markers.

// a transform stream is a readable/writable stream where you do
|

// something with the data. Sometimes it's called a "filter",
|
|
// but that's not a great name for it, since that implies a thing where
|
|
// some bits pass through, and others are simply ignored. (That would
|
|
// be a valid example of a transform, of course.)
|
|
//
|
|
// While the output is causally related to the input, it's not a
|
|
// necessarily symmetric or synchronous transformation. For example,
|
|
// a zlib stream might take multiple plain-text writes(), and then
|
|
// emit a single compressed chunk some time in the future.
|
|
//
|
|
// Here's how this works:
|
|
//
|
|
// The Transform stream has all the aspects of the readable and writable
|
|
// stream classes. When you write(chunk), that calls _write(chunk,cb)
|
|
// internally, and returns false if there's a lot of pending writes
|
|
// buffered up. When you call read(), that calls _read(n) until
|
|
// there's enough pending readable data buffered up.
|
|
//
|
|
// In a transform stream, the written data is placed in a buffer. When
|
|
// _read(n) is called, it transforms the queued up data, calling the
|
|
// buffered _write cb's as it consumes chunks. If consuming a single
|
|
// written chunk would result in multiple output chunks, then the first
|
|
// outputted bit calls the readcb, and subsequent chunks just go into
|
|
// the read buffer, and will cause it to emit 'readable' if necessary.
|
|
//
|
|
// This way, back-pressure is actually determined by the reading side,
|
|
// since _read has to be called to start processing a new chunk. However,
|
|
// a pathological inflate type of transform can cause excessive buffering
|
|
// here. For example, imagine a stream where every byte of input is
|
|
// interpreted as an integer from 0-255, and then results in that many
|
|
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
|
|
// 1kb of data being output. In this case, you could write a very small
|
|
// amount of input, and end up with a very large amount of output. In
|
|
// such a pathological inflating mechanism, there'd be no way to tell
|
|
// the system to stop doing the transform. A single 4MB write could
|
|
// cause the system to run out of memory.
|
|
//
|
|
// However, even in such a pathological case, only a single written chunk
|
|
// would be consumed, and then the rest would wait (un-transformed) until
|

* var ref = require('ref')

* var Struct = require('ref-struct')
|

*
