// 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.

* may only occur in the main thread and is the responsibility of
|
|
* ReactEventListener, which is injected and can therefore support pluggable
|
|
* event sources. This is the only work that occurs in the main thread.
|
|
*
|
|
* - We normalize and de-duplicate events to account for browser quirks. This
|
|
* may be done in the worker thread.
|
|
*
|
|
* - Forward these native events (with the associated top-level type used to
|
|
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
|
|
* to extract any synthetic events.
|
|
*
|
|
* - The `EventPluginHub` will then process each event by annotating them with
|
|
* "dispatches", a sequence of listeners and IDs that care about that event.
|
|
*
|
|
* - The `EventPluginHub` then dispatches the events.

|
|
* Firefox v8.01 (and possibly others) exhibited strange behavior when
|
|
* mounting `onmousemove` events at some node that was not the document
|
|
* element. The symptoms were that if your mouse is not moving over something
|

* top-level listeners for `onmousemove` won't be called. However, if you

* top-level listeners to the document object only, at least for these
|
|
* movement types of events and possibly all events.

|
*
|
|
* @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html
