|

|
* =============
|
|
|
*
|
|
|
* The Buffer constructor returns instances of `Uint8Array` that are augmented
|
|
|
* with function properties for all the node `Buffer` API functions. We use
|
|
|
* `Uint8Array` so that square bracket notation works as expected -- it returns
|
|
|
* a single octet.
|
|
|
*
|
|
|
* By augmenting the instances, we can avoid modifying the `Uint8Array`
|
|
|
* prototype.
|
|
|
*
|
|
|
* Firefox is a special case because it doesn't allow augmenting "native" object
|
|
|
* instances. See `ProxyBuffer` below for more details.

* Class: ProxyBuffer
|
|
|
* ==================
|
|
|
*
|
|
|
* Only used in Firefox, since Firefox does not allow augmenting "native"
|
|
|
* objects (like Uint8Array instances) with new properties for some unknown
|
|
|
* (probably silly) reason. So we'll use an ES6 Proxy (supported since
|
|
|
* Firefox 18) to wrap the Uint8Array instance without actually adding any
|
|
|
* properties to it.
|
|
|
*
|
|
|
* Instances of this "fake" Buffer class are the "target" of the
|
|
|
* ES6 Proxy (see `augment` function).
|
|
|
*
|
|
|
* We couldn't just use the `Uint8Array` as the target of the `Proxy` because
|
|
|
* Proxies have an important limitation on trapping the `toString` method.
|
|
|
* `Object.prototype.toString.call(proxy)` gets called whenever something is
|
|
|
* implicitly cast to a String. Unfortunately, with a `Proxy` this
|
|
|
* unconditionally returns `Object.prototype.toString.call(target)` which would
|
|
|
* always return "[object Uint8Array]" if we used the `Uint8Array` instance as
|
|
|
* the target. And, remember, in Firefox we cannot redefine the `Uint8Array`
|
|
|
* instance's `toString` method.
|
|
|
*
|
|
|
* So, we use this `ProxyBuffer` class as the proxy's "target". Since this class
|
|
|
* has its own custom `toString` method, it will get called whenever `toString`
|
|
|
* gets called, implicitly or explicitly, on the `Proxy` instance.
|
|
|
*
|
|
|
* We also have to define the Uint8Array methods `subarray` and `set` on
|
|
|
* `ProxyBuffer` because if we didn't then `proxy.subarray(0)` would have its
|
|
|
* `this` set to `proxy` (a `Proxy` instance) which throws an exception in
|
|
|
* Firefox which expects it to be a `TypedArray` instance.

// 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
|
|
|
