- // 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
- // the results of the previous transformed chunk were consumed.

- 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

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