2 | ## 1.5.1
|
3 |
|
4 | - Q.any now annotates its error message to clarify that Q.any was involved and
|
5 | includes only the last error emitted. (Ivan Etchart)
|
6 | - Avoid domain.dispose during tests in preparation for Node.js 9. (Anna
|
7 | Henningsen)
|
8 |
|
9 | ## 1.5.0
|
10 |
|
11 | - Q.any gives an error message from the last rejected promise
|
12 | - Throw if callback supplied to "finally" is invalid (@grahamrhay)
|
13 | - Long stack trace improvements, can now construct long stack traces
|
14 | across rethrows.
|
15 |
|
16 | ## 1.4.1
|
17 |
|
18 | - Address an issue that prevented Q from being used as a `<script>` for
|
19 | Firefox add-ons. Q can now be used in any environment that provides `window`
|
20 | or `self` globals, favoring `window` since add-ons have an an immutable
|
21 | `self` that is distinct from `window`.
|
22 |
|
23 | ## 1.4.0
|
24 |
|
25 | - Add `noConflict` support for use in `<script>` (@jahnjw).
|
26 |
|
27 | ## 1.3.0
|
28 |
|
29 | - Add tracking for unhandled and handled rejections in Node.js (@benjamingr).
|
30 |
|
31 | ## 1.2.1
|
32 |
|
33 | - Fix Node.js environment detection for modern Browserify (@kahnjw).
|
34 |
|
35 | ## 1.2.0
|
36 |
|
37 | - Added Q.any(promisesArray) method (@vergara).
|
38 | Returns a promise fulfilled with the value of the first resolved promise in
|
39 | promisesArray. If all promises in promisesArray are rejected, it returns
|
40 | a rejected promise.
|
41 |
|
42 | ## 1.1.2
|
43 |
|
44 | - Removed extraneous files from the npm package by using the "files"
|
45 | whitelist in package.json instead of the .npmignore blacklist.
|
46 | (@anton-rudeshko)
|
47 |
|
48 | ## 1.1.1
|
49 |
|
50 | - Fix a pair of regressions in bootstrapping, one which precluded
|
51 | WebWorker support, and another that precluded support in
|
52 | ``<script>`` usage outright. #607
|
53 |
|
54 | ## 1.1.0
|
55 |
|
56 | - Adds support for enabling long stack traces in node.js by setting
|
57 | environment variable `Q_DEBUG=1`.
|
58 | - Introduces the `tap` method to promises, which will see a value
|
59 | pass through without alteration.
|
60 | - Use instanceof to recognize own promise instances as opposed to
|
61 | thenables.
|
62 | - Construct timeout errors with `code === ETIMEDOUT` (Kornel Lesiński)
|
63 | - More descriminant CommonJS module environment detection.
|
64 | - Dropped continuous integration for Node.js 0.6 and 0.8 because of
|
65 | changes to npm that preclude the use of new `^` version predicate
|
66 | operator in any transitive dependency.
|
67 | - Users can now override `Q.nextTick`.
|
68 |
|
69 | ## 1.0.1
|
70 |
|
71 | - Adds support for `Q.Promise`, which implements common usage of the
|
72 | ES6 `Promise` constructor and its methods. `Promise` does not have
|
73 | a valid promise constructor and a proper implementation awaits
|
74 | version 2 of Q.
|
75 | - Removes the console stopgap for a promise inspector. This no longer
|
76 | works with any degree of reliability.
|
77 | - Fixes support for content security policies that forbid eval. Now
|
78 | using the `StopIteration` global to distinguish SpiderMonkey
|
79 | generators from ES6 generators, assuming that they will never
|
80 | coexist.
|
81 |
|
82 | ## 1.0.0
|
83 |
|
84 | :cake: This is all but a re-release of version 0.9, which has settled
|
85 | into a gentle maintenance mode and rightly deserves an official 1.0.
|
86 | An ambitious 2.0 release is already around the corner, but 0.9/1.0
|
87 | have been distributed far and wide and demand long term support.
|
88 |
|
89 | - Q will now attempt to post a debug message in browsers regardless
|
90 | of whether window.Touch is defined. Chrome at least now has this
|
91 | property regardless of whether touch is supported by the underlying
|
92 | hardware.
|
93 | - Remove deprecation warning from `promise.valueOf`. The function is
|
94 | called by the browser in various ways so there is no way to
|
95 | distinguish usage that should be migrated from usage that cannot be
|
96 | altered.
|
97 |
|
98 | ## 0.9.7
|
99 |
|
100 | - :warning: `q.min.js` is no longer checked-in. It is however still
|
101 | created by Grunt and NPM.
|
102 | - Fixes a bug that inhibited `Q.async` with implementations of the new
|
103 | ES6 generators.
|
104 | - Fixes a bug with `nextTick` affecting Safari 6.0.5 the first time a
|
105 | page loads when an `iframe` is involved.
|
106 | - Introduces `passByCopy`, `join`, and `race`.
|
107 | - Shows stack traces or error messages on the console, instead of
|
108 | `Error` objects.
|
109 | - Elimintates wrapper methods for improved performance.
|
110 | - `Q.all` now propagates progress notifications of the form you might
|
111 | expect of ES6 iterations, `{value, index}` where the `value` is the
|
112 | progress notification from the promise at `index`.
|
113 |
|
114 | ## 0.9.6
|
115 |
|
116 | - Fixes a bug in recognizing the difference between compatible Q
|
117 | promises, and Q promises from before the implementation of "inspect".
|
118 | The latter are now coerced.
|
119 | - Fixes an infinite asynchronous coercion cycle introduced by former
|
120 | solution, in two independently sufficient ways. 1.) All promises
|
121 | returned by makePromise now implement "inspect", albeit a default
|
122 | that reports that the promise has an "unknown" state. 2.) The
|
123 | implementation of "then/when" is now in "then" instead of "when", so
|
124 | that the responsibility to "coerce" the given promise rests solely in
|
125 | the "when" method and the "then" method may assume that "this" is a
|
126 | promise of the right type.
|
127 | - Refactors `nextTick` to use an unrolled microtask within Q regardless
|
128 | of how new ticks a requested. #316 @rkatic
|
129 |
|
130 | ## 0.9.5
|
131 |
|
132 | - Introduces `inspect` for getting the state of a promise as
|
133 | `{state: "fulfilled" | "rejected" | "pending", value | reason}`.
|
134 | - Introduces `allSettled` which produces an array of promises states
|
135 | for the input promises once they have all "settled". This is in
|
136 | accordance with a discussion on Promises/A+ that "settled" refers to
|
137 | a promise that is "fulfilled" or "rejected". "resolved" refers to a
|
138 | deferred promise that has been "resolved" to another promise,
|
139 | "sealing its fate" to the fate of the successor promise.
|
140 | - Long stack traces are now off by default. Set `Q.longStackSupport`
|
141 | to true to enable long stack traces.
|
142 | - Long stack traces can now follow the entire asynchronous history of a
|
143 | promise, not just a single jump.
|
144 | - Introduces `spawn` for an immediately invoked asychronous generator.
|
145 | @jlongster
|
146 | - Support for *experimental* synonyms `mapply`, `mcall`, `nmapply`,
|
147 | `nmcall` for method invocation.
|
148 |
|
149 | ## 0.9.4
|
150 |
|
151 | - `isPromise` and `isPromiseAlike` now always returns a boolean
|
152 | (even for falsy values). #284 @lfac-pt
|
153 | - Support for ES6 Generators in `async` #288 @andywingo
|
154 | - Clear duplicate promise rejections from dispatch methods #238 @SLaks
|
155 | - Unhandled rejection API #296 @domenic
|
156 | `stopUnhandledRejectionTracking`, `getUnhandledReasons`,
|
157 | `resetUnhandledRejections`.
|
158 |
|
159 | ## 0.9.3
|
160 |
|
161 | - Add the ability to give `Q.timeout`'s errors a custom error message. #270
|
162 | @jgrenon
|
163 | - Fix Q's call-stack busting behavior in Node.js 0.10, by switching from
|
164 | `process.nextTick` to `setImmediate`. #254 #259
|
165 | - Fix Q's behavior when used with the Mocha test runner in the browser, since
|
166 | Mocha introduces a fake `process` global without a `nextTick` property. #267
|
167 | - Fix some, but not all, cases wherein Q would give false positives in its
|
168 | unhandled rejection detection (#252). A fix for other cases (#238) is
|
169 | hopefully coming soon.
|
170 | - Made `Q.promise` throw early if given a non-function.
|
171 |
|
172 | ## 0.9.2
|
173 |
|
174 | - Pass through progress notifications when using `timeout`. #229 @omares
|
175 | - Pass through progress notifications when using `delay`.
|
176 | - Fix `nbind` to actually bind the `thisArg`. #232 @davidpadbury
|
177 |
|
178 | ## 0.9.1
|
179 |
|
180 | - Made the AMD detection compatible with the RequireJS optimizer's `namespace`
|
181 | option. #225 @terinjokes
|
182 | - Fix side effects from `valueOf`, and thus from `isFulfilled`, `isRejected`,
|
183 | and `isPending`. #226 @benjamn
|
184 |
|
185 | ## 0.9.0
|
186 |
|
187 | This release removes many layers of deprecated methods and brings Q closer to
|
188 | alignment with Mark Miller’s TC39 [strawman][] for concurrency. At the same
|
189 | time, it fixes many bugs and adds a few features around error handling. Finally,
|
190 | it comes with an updated and comprehensive [API Reference][].

195 | ### API Cleanup
|
196 |
|
197 | The following deprecated or undocumented methods have been removed.

258 |
|
259 |
|
260 | (*) Use of ``thisp`` is discouraged. For calling methods, use ``post`` or
|
261 | ``invoke``.
|
262 |
|
263 | ### Alignment with the Concurrency Strawman
|
264 |
|
265 | - Q now exports a `Q(value)` function, an alias for `resolve`.
|
266 | `Q.call`, `Q.apply`, and `Q.bind` were removed to make room for the
|
267 | same methods on the function prototype.
|
268 | - `invoke` has been aliased to `send` in all its forms.
|
269 | - `post` with no method name acts like `fapply`.
|
270 |
|
271 | ### Error Handling
|
272 |
|
273 | - Long stack traces can be turned off by setting `Q.stackJumpLimit` to zero.
|
274 | In the future, this property will be used to fine tune how many stack jumps
|
275 | are retained in long stack traces; for now, anything nonzero is treated as
|
276 | one (since Q only tracks one stack jump at the moment, see #144). #168
|
277 | - In Node.js, if there are unhandled rejections when the process exits, they
|
278 | are output to the console. #115
|
279 |
|
280 | ### Other
|
281 |
|
282 | - `delete` and `set` (née `put`) no longer have a fulfillment value.
|
283 | - Q promises are no longer frozen, which
|
284 | [helps with performance](http://code.google.com/p/v8/issues/detail?id=1858).
|
285 | - `thenReject` is now included, as a counterpart to `thenResolve`.
|
286 | - The included browser `nextTick` shim is now faster. #195 @rkatic.
|
287 |
|
288 | ### Bug Fixes
|
289 |
|
290 | - Q now works in Internet Explorer 10. #186 @ForbesLindesay
|
291 | - `fbind` no longer hard-binds the returned function's `this` to `undefined`.
|
292 | #202
|
293 | - `Q.reject` no longer leaks memory. #148
|
294 | - `npost` with no arguments now works. #207
|
295 | - `allResolved` now works with non-Q promises ("thenables"). #179
|
296 | - `keys` behavior is now correct even in browsers without native
|
297 | `Object.keys`. #192 @rkatic
|
298 | - `isRejected` and the `exception` property now work correctly if the
|
299 | rejection reason is falsy. #198
|
300 |
|
301 | ### Internals and Advanced
|
302 |
|
303 | - The internal interface for a promise now uses
|
304 | `dispatchPromise(resolve, op, operands)` instead of `sendPromise(op,
|
305 | resolve, ...operands)`, which reduces the cases where Q needs to do
|
306 | argument slicing.
|
307 | - The internal protocol uses different operands. "put" is now "set".
|
308 | "del" is now "delete". "view" and "viewInfo" have been removed.
|
309 | - `Q.fulfill` has been added. It is distinct from `Q.resolve` in that
|
310 | it does not pass promises through, nor coerces promises from other
|
311 | systems. The promise becomes the fulfillment value. This is only
|
312 | recommended for use when trying to fulfill a promise with an object that has
|
313 | a `then` function that is at the same time not a promise.
|
314 |
|
315 | ## 0.8.12
|
316 | - Treat foreign promises as unresolved in `Q.isFulfilled`; this lets `Q.all`
|
317 | work on arrays containing foreign promises. #154
|
318 | - Fix minor incompliances with the [Promises/A+ spec][] and [test suite][]. #157
|
319 | #158
|
320 |
|
321 | [Promises/A+ spec]: http://promises-aplus.github.com/promises-spec/
|
322 | [test suite]: https://github.com/promises-aplus/promises-tests
|
323 |
|
324 | ## 0.8.11
|
325 |
|
326 | - Added ``nfcall``, ``nfapply``, and ``nfbind`` as ``thisp``-less versions of
|
327 | ``ncall``, ``napply``, and ``nbind``. The latter are now deprecated. #142
|
328 | - Long stack traces no longer cause linearly-growing memory usage when chaining
|
329 | promises together. #111
|
330 | - Inspecting ``error.stack`` in a rejection handler will now give a long stack
|
331 | trace. #103
|
332 | - Fixed ``Q.timeout`` to clear its timeout handle when the promise is rejected;
|
333 | previously, it kept the event loop alive until the timeout period expired.
|
334 | #145 @dfilatov
|
335 | - Added `q/queue` module, which exports an infinite promise queue
|
336 | constructor.
|
337 |
|
338 | ## 0.8.10
|
339 |
|
340 | - Added ``done`` as a replacement for ``end``, taking the usual fulfillment,
|
341 | rejection, and progress handlers. It's essentially equivalent to
|
342 | ``then(f, r, p).end()``.
|
343 | - Added ``Q.onerror``, a settable error trap that you can use to get full stack
|
344 | traces for uncaught errors. #94
|
345 | - Added ``thenResolve`` as a shortcut for returning a constant value once a
|
346 | promise is fulfilled. #108 @ForbesLindesay
|
347 | - Various tweaks to progress notification, including propagation and
|
348 | transformation of progress values and only forwarding a single progress
|
349 | object.
|
350 | - Renamed ``nend`` to ``nodeify``. It no longer returns an always-fulfilled
|
351 | promise when a Node callback is passed.
|
352 | - ``deferred.resolve`` and ``deferred.reject`` no longer (sometimes) return
|
353 | ``deferred.promise``.
|
354 | - Fixed stack traces getting mangled if they hit ``end`` twice. #116 #121 @ef4
|
355 | - Fixed ``ninvoke`` and ``npost`` to work on promises for objects with Node
|
356 | methods. #134
|
357 | - Fixed accidental coercion of objects with nontrivial ``valueOf`` methods,
|
358 | like ``Date``s, by the promise's ``valueOf`` method. #135
|
359 | - Fixed ``spread`` not calling the passed rejection handler if given a rejected
|
360 | promise.
|
361 |
|
362 | ## 0.8.9
|
363 |
|
364 | - Added ``nend``
|
365 | - Added preliminary progress notification support, via
|
366 | ``promise.then(onFulfilled, onRejected, onProgress)``,
|
367 | ``promise.progress(onProgress)``, and ``deferred.notify(...progressData)``.
|
368 | - Made ``put`` and ``del`` return the object acted upon for easier chaining.
|
369 | #84
|
370 | - Fixed coercion cycles with cooperating promises. #106
|
371 |
|
372 | ## 0.8.7
|
373 |
|
374 | - Support [Montage Require](http://github.com/kriskowal/mr)
|
375 |
|
376 | ## 0.8.6
|
377 |
|
378 | - Fixed ``npost`` and ``ninvoke`` to pass the correct ``thisp``. #74
|
379 | - Fixed various cases involving unorthodox rejection reasons. #73 #90
|
380 | @ef4
|
381 | - Fixed double-resolving of misbehaved custom promises. #75
|
382 | - Sped up ``Q.all`` for arrays contain already-resolved promises or scalar
|
383 | values. @ForbesLindesay
|
384 | - Made stack trace filtering work when concatenating assets. #93 @ef4
|
385 | - Added warnings for deprecated methods. @ForbesLindesay
|
386 | - Added ``.npmignore`` file so that dependent packages get a slimmer
|
387 | ``node_modules`` directory.
|
388 |
|
389 | ## 0.8.5
|
390 |
|
391 | - Added preliminary support for long traces (@domenic)
|
392 | - Added ``fapply``, ``fcall``, ``fbind`` for non-thisp
|
393 | promised function calls.
|
394 | - Added ``return`` for async generators, where generators
|
395 | are implemented.
|
396 | - Rejected promises now have an "exception" property. If an object
|
397 | isRejected(object), then object.valueOf().exception will
|
398 | be the wrapped error.
|
399 | - Added Jasmine specifications
|
400 | - Support Internet Explorers 7–9 (with multiple bug fixes @domenic)
|
401 | - Support Firefox 12
|
402 | - Support Safari 5.1.5
|
403 | - Support Chrome 18
|
404 |
|
405 | ## 0.8.4
|
406 |
|
407 | - WARNING: ``promise.timeout`` is now rejected with an ``Error`` object
|
408 | and the message now includes the duration of the timeout in
|
409 | miliseconds. This doesn't constitute (in my opinion) a
|
410 | backward-incompatibility since it is a change of an undocumented and
|
411 | unspecified public behavior, but if you happened to depend on the
|
412 | exception being a string, you will need to revise your code.
|
413 | - Added ``deferred.makeNodeResolver()`` to replace the more cryptic
|
414 | ``deferred.node()`` method.
|
415 | - Added experimental ``Q.promise(maker(resolve, reject))`` to make a
|
416 | promise inside a callback, such that thrown exceptions in the
|
417 | callback are converted and the resolver and rejecter are arguments.
|
418 | This is a shorthand for making a deferred directly and inspired by
|
419 | @gozala’s stream constructor pattern and the Microsoft Windows Metro
|
420 | Promise constructor interface.
|
421 | - Added experimental ``Q.begin()`` that is intended to kick off chains
|
422 | of ``.then`` so that each of these can be reordered without having to
|
423 | edit the new and former first step.
|
424 |
|
425 | ## 0.8.3
|
426 |
|
427 | - Added ``isFulfilled``, ``isRejected``, and ``isResolved``
|
428 | to the promise prototype.
|
429 | - Added ``allResolved`` for waiting for every promise to either be
|
430 | fulfilled or rejected, without propagating an error. @utvara #53
|
431 | - Added ``Q.bind`` as a method to transform functions that
|
432 | return and throw into promise-returning functions. See
|
433 | [an example](https://gist.github.com/1782808). @domenic
|
434 | - Renamed ``node`` export to ``nbind``, and added ``napply`` to
|
435 | complete the set. ``node`` remains as deprecated. @domenic #58
|
436 | - Renamed ``Method`` export to ``sender``. ``Method``
|
437 | remains as deprecated and will be removed in the next
|
438 | major version since I expect it has very little usage.
|
439 | - Added browser console message indicating a live list of
|
440 | unhandled errors.
|
441 | - Added support for ``msSetImmediate`` (IE10) or ``setImmediate``
|
442 | (available via [polyfill](https://github.com/NobleJS/setImmediate))
|
443 | as a browser-side ``nextTick`` implementation. #44 #50 #59
|
444 | - Stopped using the event-queue dependency, which was in place for
|
445 | Narwhal support: now directly using ``process.nextTick``.
|
446 | - WARNING: EXPERIMENTAL: added ``finally`` alias for ``fin``, ``catch``
|
447 | alias for ``fail``, ``try`` alias for ``call``, and ``delete`` alias
|
448 | for ``del``. These properties are enquoted in the library for
|
449 | cross-browser compatibility, but may be used as property names in
|
450 | modern engines.
|
451 |
|
452 | ## 0.8.2
|
453 |
|
454 | - Deprecated ``ref`` in favor of ``resolve`` as recommended by
|
455 | @domenic.
|
456 | - Update event-queue dependency.
|
457 |
|
458 | ## 0.8.1
|
459 |
|
460 | - Fixed Opera bug. #35 @cadorn
|
461 | - Fixed ``Q.all([])`` #32 @domenic
|
462 |
|
463 | ## 0.8.0
|
464 |
|
465 | - WARNING: ``enqueue`` removed. Use ``nextTick`` instead.
|
466 | This is more consistent with NodeJS and (subjectively)
|
467 | more explicit and intuitive.
|
468 | - WARNING: ``def`` removed. Use ``master`` instead. The
|
469 | term ``def`` was too confusing to new users.
|
470 | - WARNING: ``spy`` removed in favor of ``fin``.
|
471 | - WARNING: ``wait`` removed. Do ``all(args).get(0)`` instead.
|
472 | - WARNING: ``join`` removed. Do ``all(args).spread(callback)`` instead.
|
473 | - WARNING: Removed the ``Q`` function module.exports alias
|
474 | for ``Q.ref``. It conflicts with ``Q.apply`` in weird
|
475 | ways, making it uncallable.
|
476 | - Revised ``delay`` so that it accepts both ``(value,
|
477 | timeout)`` and ``(timeout)`` variations based on
|
478 | arguments length.
|
479 | - Added ``ref().spread(cb(...args))``, a variant of
|
480 | ``then`` that spreads an array across multiple arguments.
|
481 | Useful with ``all()``.
|
482 | - Added ``defer().node()`` Node callback generator. The
|
483 | callback accepts ``(error, value)`` or ``(error,
|
484 | ...values)``. For multiple value arguments, the
|
485 | fulfillment value is an array, useful in conjunction with
|
486 | ``spread``.
|
487 | - Added ``node`` and ``ncall``, both with the signature
|
488 | ``(fun, thisp_opt, ...args)``. The former is a decorator
|
489 | and the latter calls immediately. ``node`` optional
|
490 | binds and partially applies. ``ncall`` can bind and pass
|
491 | arguments.
|
492 |
|
493 | ## 0.7.2
|
494 |
|
495 | - Fixed thenable promise assimilation.
|
496 |
|
497 | ## 0.7.1
|
498 |
|
499 | - Stopped shimming ``Array.prototype.reduce``. The
|
500 | enumerable property has bad side-effects. Libraries that
|
501 | depend on this (for example, QQ) will need to be revised.
|
502 |
|
503 | ## 0.7.0 - BACKWARD INCOMPATIBILITY
|
504 |
|
505 | - WARNING: Removed ``report`` and ``asap``
|
506 | - WARNING: The ``callback`` argument of the ``fin``
|
507 | function no longer receives any arguments. Thus, it can
|
508 | be used to call functions that should not receive
|
509 | arguments on resolution. Use ``when``, ``then``, or
|
510 | ``fail`` if you need a value.
|
511 | - IMPORTANT: Fixed a bug in the use of ``MessageChannel``
|
512 | for ``nextTick``.
|
513 | - Renamed ``enqueue`` to ``nextTick``.
|
514 | - Added experimental ``view`` and ``viewInfo`` for creating
|
515 | views of promises either when or before they're
|
516 | fulfilled.
|
517 | - Shims are now externally applied so subsequent scripts or
|
518 | dependees can use them.
|
519 | - Improved minification results.
|
520 | - Improved readability.
|
521 |
|
522 | ## 0.6.0 - BACKWARD INCOMPATIBILITY
|
523 |
|
524 | - WARNING: In practice, the implementation of ``spy`` and
|
525 | the name ``fin`` were useful. I've removed the old
|
526 | ``fin`` implementation and renamed/aliased ``spy``.
|
527 | - The "q" module now exports its ``ref`` function as a "Q"
|
528 | constructor, with module systems that support exports
|
529 | assignment including NodeJS, RequireJS, and when used as
|
530 | a ``<script>`` tag. Notably, strictly compliant CommonJS
|
531 | does not support this, but UncommonJS does.
|
532 | - Added ``async`` decorator for generators that use yield
|
533 | to "trampoline" promises. In engines that support
|
534 | generators (SpiderMonkey), this will greatly reduce the
|
535 | need for nested callbacks.
|
536 | - Made ``when`` chainable.
|
537 | - Made ``all`` chainable.
|
538 |
|
539 | ## 0.5.3
|
540 |
|
541 | - Added ``all`` and refactored ``join`` and ``wait`` to use
|
542 | it. All of these will now reject at the earliest
|
543 | rejection.
|
544 |
|
545 | ## 0.5.2
|
546 |
|
547 | - Minor improvement to ``spy``; now waits for resolution of
|
548 | callback promise.
|
549 |
|
550 | ## 0.5.1
|
551 |
|
552 | - Made most Q API methods chainable on promise objects, and
|
553 | turned the previous promise-methods of ``join``,
|
554 | ``wait``, and ``report`` into Q API methods.
|
555 | - Added ``apply`` and ``call`` to the Q API, and ``apply``
|
556 | as a promise handler.
|
557 | - Added ``fail``, ``fin``, and ``spy`` to Q and the promise
|
558 | prototype for convenience when observing rejection,
|
559 | fulfillment and rejection, or just observing without
|
560 | affecting the resolution.
|
561 | - Renamed ``def`` (although ``def`` remains shimmed until
|
562 | the next major release) to ``master``.
|
563 | - Switched to using ``MessageChannel`` for next tick task
|
564 | enqueue in browsers that support it.
|
565 |
|
566 | ## 0.5.0 - MINOR BACKWARD INCOMPATIBILITY
|
567 |
|
568 | - Exceptions are no longer reported when consumed.
|
569 | - Removed ``error`` from the API. Since exceptions are
|
570 | getting consumed, throwing them in an errback causes the
|
571 | exception to silently disappear. Use ``end``.
|
572 | - Added ``end`` as both an API method and a promise-chain
|
573 | ending method. It causes propagated rejections to be
|
574 | thrown, which allows Node to write stack traces and
|
575 | emit ``uncaughtException`` events, and browsers to
|
576 | likewise emit ``onerror`` and log to the console.
|
577 | - Added ``join`` and ``wait`` as promise chain functions,
|
578 | so you can wait for variadic promises, returning your own
|
579 | promise back, or join variadic promises, resolving with a
|
580 | callback that receives variadic fulfillment values.
|
581 |
|
582 | ## 0.4.4
|
583 |
|
584 | - ``end`` no longer returns a promise. It is the end of the
|
585 | promise chain.
|
586 | - Stopped reporting thrown exceptions in ``when`` callbacks
|
587 | and errbacks. These must be explicitly reported through
|
588 | ``.end()``, ``.then(null, Q.error)``, or some other
|
589 | mechanism.
|
590 | - Added ``report`` as an API method, which can be used as
|
591 | an errback to report and propagate an error.
|
592 | - Added ``report`` as a promise-chain method, so an error
|
593 | can be reported if it passes such a gate.
|
594 |
|
595 | ## 0.4.3
|
596 |
|
597 | - Fixed ``<script>`` support that regressed with 0.4.2
|
598 | because of "use strict" in the module system
|
599 | multi-plexer.
|
600 |
|
601 | ## 0.4.2
|
602 |
|
603 | - Added support for RequireJS (jburke)
|
604 |
|
605 | ## 0.4.1
|
606 |
|
607 | - Added an "end" method to the promise prototype,
|
608 | as a shorthand for waiting for the promise to
|
609 | be resolved gracefully, and failing to do so,
|
610 | to dump an error message.
|
611 |
|
612 | ## 0.4.0 - BACKWARD INCOMPATIBLE*
|
613 |
|
614 | - *Removed the utility modules. NPM and Node no longer
|
615 | expose any module except the main module. These have
|
616 | been moved and merged into the "qq" package.
|
617 | - *In a non-CommonJS browser, q.js can be used as a script.
|
618 | It now creates a Q global variable.
|
619 | - Fixed thenable assimilation.
|
620 | - Fixed some issues with asap, when it resolves to
|
621 | undefined, or throws an exception.
|
622 |
|
623 | ## 0.3.0 - BACKWARD-INCOMPATIBLE
|
624 |
|
625 | - The `post` method has been reverted to its original
|
626 | signature, as provided in Tyler Close's `ref_send` API.
|
627 | That is, `post` accepts two arguments, the second of
|
628 | which is an arbitrary object, but usually invocation
|
629 | arguments as an `Array`. To provide variadic arguments
|
630 | to `post`, there is a new `invoke` function that posts
|
631 | the variadic arguments to the value given in the first
|
632 | argument.
|
633 | - The `defined` method has been moved from `q` to `q/util`
|
634 | since it gets no use in practice but is still
|
635 | theoretically useful.
|
636 | - The `Promise` constructor has been renamed to
|
637 | `makePromise` to be consistent with the convention that
|
638 | functions that do not require the `new` keyword to be
|
639 | used as constructors have camelCase names.
|
640 | - The `isResolved` function has been renamed to
|
641 | `isFulfilled`. There is a new `isResolved` function that
|
642 | indicates whether a value is not a promise or, if it is a
|
643 | promise, whether it has been either fulfilled or
|
644 | rejected. The code has been revised to reflect this
|
645 | nuance in terminology.
|
646 |
|
647 | ## 0.2.10
|
648 |
|
649 | - Added `join` to `"q/util"` for variadically joining
|
650 | multiple promises.
|
651 |
|
652 | ## 0.2.9
|
653 |
|
654 | - The future-compatible `invoke` method has been added,
|
655 | to replace `post`, since `post` will become backward-
|
656 | incompatible in the next major release.
|
657 | - Exceptions thrown in the callbacks of a `when` call are
|
658 | now emitted to Node's `"uncaughtException"` `process`
|
659 | event in addition to being returned as a rejection reason.
|
660 |
|
661 | ## 0.2.8
|
662 |
|
663 | - Exceptions thrown in the callbacks of a `when` call
|
664 | are now consumed, warned, and transformed into
|
665 | rejections of the promise returned by `when`.
|
666 |
|
667 | ## 0.2.7
|
668 |
|
669 | - Fixed a minor bug in thenable assimilation, regressed
|
670 | because of the change in the forwarding protocol.
|
671 | - Fixed behavior of "q/util" `deep` method on dates and
|
672 | other primitives. Github issue #11.
|
673 |
|
674 | ## 0.2.6
|
675 |
|
676 | - Thenables (objects with a "then" method) are accepted
|
677 | and provided, bringing this implementation of Q
|
678 | into conformance with Promises/A, B, and D.
|
679 | - Added `makePromise`, to replace the `Promise` function
|
680 | eventually.
|
681 | - Rejections are now also duck-typed. A rejection is a
|
682 | promise with a valueOf method that returns a rejection
|
683 | descriptor. A rejection descriptor has a
|
684 | "promiseRejected" property equal to "true" and a
|
685 | "reason" property corresponding to the rejection reason.
|
686 | - Altered the `makePromise` API such that the `fallback`
|
687 | method no longer receives a superfluous `resolved` method
|
688 | after the `operator`. The fallback method is responsible
|
689 | only for returning a resolution. This breaks an
|
690 | undocumented API, so third-party API's depending on the
|
691 | previous undocumented behavior may break.
|
692 |
|
693 | ## 0.2.5
|
694 |
|
695 | - Changed promises into a duck-type such that multiple
|
696 | instances of the Q module can exchange promise objects.
|
697 | A promise is now defined as "an object that implements the
|
698 | `promiseSend(op, resolved, ...)` method and `valueOf`".
|
699 | - Exceptions in promises are now captured and returned
|
700 | as rejections.
|
701 |
|
702 | ## 0.2.4
|
703 |
|
704 | - Fixed bug in `ref` that prevented `del` messages from
|
705 | being received (gozala)
|
706 | - Fixed a conflict with FireFox 4; constructor property
|
707 | is now read-only.
|
708 |
|
709 | ## 0.2.3
|
710 |
|
711 | - Added `keys` message to promises and to the promise API.
|
712 |
|
713 | ## 0.2.2
|
714 |
|
715 | - Added boilerplate to `q/queue` and `q/util`.
|
716 | - Fixed missing dependency to `q/queue`.
|
717 |
|
718 | ## 0.2.1
|
719 |
|
720 | - The `resolve` and `reject` methods of `defer` objects now
|
721 | return the resolution promise for convenience.
|
722 | - Added `q/util`, which provides `step`, `delay`, `shallow`,
|
723 | `deep`, and three reduction orders.
|
724 | - Added `q/queue` module for a promise `Queue`.
|
725 | - Added `q-comm` to the list of compatible libraries.
|
726 | - Deprecated `defined` from `q`, with intent to move it to
|
727 | `q/util`.
|
728 |
|
729 | ## 0.2.0 - BACKWARD INCOMPATIBLE
|
730 |
|
731 | - Changed post(ref, name, args) to variadic
|
732 | post(ref, name, ...args). BACKWARD INCOMPATIBLE
|
733 | - Added a def(value) method to annotate an object as being
|
734 | necessarily a local value that cannot be serialized, such
|
735 | that inter-process/worker/vat promise communication
|
736 | libraries will send messages to it, but never send it
|
737 | back.
|
738 | - Added a send(value, op, ...args) method to the public API, for
|
739 | forwarding messages to a value or promise in a future turn.
|
740 |
|
741 | ## 0.1.9
|
742 |
|
743 | - Added isRejected() for testing whether a value is a rejected
|
744 | promise. isResolved() retains the behavior of stating
|
745 | that rejected promises are not resolved.
|
746 |
|
747 | ## 0.1.8
|
748 |
|
749 | - Fixed isResolved(null) and isResolved(undefined) [issue #9]
|
750 | - Fixed a problem with the Object.create shim
|
751 |
|
752 | ## 0.1.7
|
753 |
|
754 | - shimmed ES5 Object.create in addition to Object.freeze
|
755 | for compatibility on non-ES5 engines (gozala)
|
756 |
|
757 | ## 0.1.6
|
758 |
|
759 | - Q.isResolved added
|
760 | - promise.valueOf() now returns the value of resolved
|
761 | and near values
|
762 | - asap retried
|
763 | - promises are frozen when possible
|
764 |
|
765 | ## 0.1.5
|
766 |
|
767 | - fixed dependency list for Teleport (gozala)
|
768 | - all unit tests now pass (gozala)
|
769 |
|
770 | ## 0.1.4
|
771 |
|
772 | - added support for Teleport as an engine (gozala)
|
773 | - simplified and updated methods for getting internal
|
774 | print and enqueue functions universally (gozala)
|
775 |
|
776 | ## 0.1.3
|
777 |
|
778 | - fixed erroneous link to the q module in package.json
|
779 |
|
780 | ## 0.1.2
|
781 |
|
782 | - restructured for overlay style package compatibility
|
783 |
|
784 | ## 0.1.0
|
785 |
|
786 | - removed asap because it was broken, probably down to the
|
787 | philosophy.
|
788 |
|
789 | ## 0.0.3
|
790 |
|
791 | - removed q-util
|
792 | - fixed asap so it returns a value if completed
|
793 |
|
794 | ## 0.0.2
|
795 |
|
796 | - added q-util
|
797 |
|
798 | ## 0.0.1
|
799 |
|
800 | - initial version
|
