// 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.

     * A dependency-injected version of the {@link async.auto} function. Dependent
     * tasks are specified as parameters to the function, after the usual callback
     * parameter, with the parameter names matching the names of the tasks it
     * depends on. This can provide even more readable task graphs which can be
     * easier to maintain.
     *
     * If a final callback is specified, the task results are similarly injected,
     * specified as named parameters after the initial error parameter.
     *
     * The autoInject function is purely syntactic sugar and its semantics are
     * otherwise equivalent to {@link async.auto}.
     *
     * @name autoInject
     * @static
     * @memberOf async
     * @see async.auto
     * @category Control Flow
     * @param {Object} tasks - An object, each of whose properties is a function of
     * the form 'func([dependencies...], callback). The object's key of a property
     * serves as the name of the task defined by that property, i.e. can be used
     * when specifying requirements for other tasks.
     * * The `callback` parameter is a `callback(err, result)` which must be called
     *   when finished, passing an `error` (which can be `null`) and the result of
     *   the function's execution. The remaining parameters name other tasks on
     *   which the task is dependent, and the results from those tasks are the
     *   arguments of those parameters.
     * @param {Function} [callback] - An optional callback which is called when all
     * the tasks have been completed. It receives the `err` argument if any `tasks`
     * pass an error to their callback. The remaining parameters are task names
     * whose results you are interested in. This callback will only be called when
     * all tasks have finished or an error has occurred, and so do not specify
     * dependencies in the same way as `tasks` do. If an error occurs, no further
     * `tasks` will be performed, and `results` will only be valid for those tasks
     * which managed to complete. Invoked with (err, [results...]).
     * @example
     *
     * //  The example from `auto` can be rewritten as follows:
     * async.autoInject({

     *         // async code to get some data
     *         callback(null, 'data', 'converted to array');
     *     },
     *     make_folder: function(callback) {
     *         // async code to create a directory to store a file in
     *         // this is run at the same time as getting the data
     *         callback(null, 'folder');
     *     },
     *     write_file: function(get_data, make_folder, callback) {
     *         // once there is some data and the directory exists,
     *         // write the data to a file in the directory
     *         callback(null, 'filename');
     *     },
     *     email_link: function(write_file, callback) {
     *         // once the file is written let's email a link to it...
     *         // write_file contains the filename returned by write_file.
     *         callback(null, {'file':write_file, 'email':'[email protected]'});
     *     }
     * }, function(err, email_link) {
     *     console.log('err = ', err);
     *     console.log('email_link = ', email_link);
     * });
     *
     * // If you are using a JS minifier that mangles parameter names, `autoInject`
     * // will not work with plain functions, since the parameter names will be
     * // collapsed to a single letter identifier.  To work around this, you can
     * // explicitly specify the names of the parameters your task function needs
     * // in an array, similar to Angular.js dependency injection.  The final
     * // results callback can be provided as an array in the same way.
     *
     * // This still has an advantage over plain `auto`, since the results a task
     * // depends on are still spread into arguments.

     * @name retry
     * @static
     * @memberOf async
     * @category Control Flow
     * @param {Object|number} [opts = {times: 5, interval: 0}| 5] - Can be either an
     * object with `times` and `interval` or a number.
     * * `times` - The number of attempts to make before giving up.  The default
     *   is `5`.
     * * `interval` - The time to wait between retries, in milliseconds.  The
     *   default is `0`. The interval may also be specified as a function of the
     *   retry count (see example).
     * * If `opts` is a number, the number specifies the number of times to retry,

     * @param {Function} task - A function which receives two arguments: (1) a
     * `callback(err, result)` which must be called when finished, passing `err`
     * (which can be `null`) and the `result` of the function's execution, and (2)
     * a `results` object, containing the results of the previously executed
     * functions (if nested inside another control flow). Invoked with
     * (callback, results).
     * @param {Function} [callback] - An optional callback which is called when the
     * task has succeeded, or after the final failed attempt. It receives the `err`
     * and `result` arguments of the last attempt at completing the `task`. Invoked
     * with (err, results).

     *
     * // The `retry` function can be used as a stand-alone control flow by passing
     * // a callback, as shown below:
     *
     * // try calling apiMethod 3 times

     * async.retry({times: 3, interval: 200}, apiMethod, function(err, result) {
     *     // do something with the result
     * });
     *
     * // try calling apiMethod 10 times with exponential backoff
     * // (i.e. intervals of 100, 200, 400, 800, 1600, ... milliseconds)
     * async.retry({
     *   times: 10,
     *   interval: function(retryCount) {
     *     return 50 * Math.pow(2, retryCount);

     * async.retry(apiMethod, function(err, result) {

// 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.

// 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.

// 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.

// 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.
