## 1.5.1
|
||
|
||
- Q.any now annotates its error message to clarify that Q.any was involved and
|
||
includes only the last error emitted. (Ivan Etchart)
|
||
- Avoid domain.dispose during tests in preparation for Node.js 9. (Anna
|
||
Henningsen)
|
||
|
||
## 1.5.0
|
||
|
||
- Q.any gives an error message from the last rejected promise
|
||
- Throw if callback supplied to "finally" is invalid (@grahamrhay)
|
||
- Long stack trace improvements, can now construct long stack traces
|
||
across rethrows.
|
||
|
||
## 1.4.1
|
||
|
||
- Address an issue that prevented Q from being used as a `<script>` for
|
||
Firefox add-ons. Q can now be used in any environment that provides `window`
|
||
or `self` globals, favoring `window` since add-ons have an an immutable
|
||
`self` that is distinct from `window`.
|
||
|
||
## 1.4.0
|
||
|
||
- Add `noConflict` support for use in `<script>` (@jahnjw).
|
||
|
||
## 1.3.0
|
||
|
||
- Add tracking for unhandled and handled rejections in Node.js (@benjamingr).
|
||
|
||
## 1.2.1
|
||
|
||
- Fix Node.js environment detection for modern Browserify (@kahnjw).
|
||
|
||
## 1.2.0
|
||
|
||
- Added Q.any(promisesArray) method (@vergara).
|
||
Returns a promise fulfilled with the value of the first resolved promise in
|
||
promisesArray. If all promises in promisesArray are rejected, it returns
|
||
a rejected promise.
|
||
|
||
## 1.1.2
|
||
|
||
- Removed extraneous files from the npm package by using the "files"
|
||
whitelist in package.json instead of the .npmignore blacklist.
|
||
(@anton-rudeshko)
|
||
|
||
## 1.1.1
|
||
|
||
- Fix a pair of regressions in bootstrapping, one which precluded
|
||
WebWorker support, and another that precluded support in
|
||
``<script>`` usage outright. #607
|
||
|
||
## 1.1.0
|
||
|
||
- Adds support for enabling long stack traces in node.js by setting
|
||
environment variable `Q_DEBUG=1`.
|
||
- Introduces the `tap` method to promises, which will see a value
|
||
pass through without alteration.
|
||
- Use instanceof to recognize own promise instances as opposed to
|
||
thenables.
|
||
- Construct timeout errors with `code === ETIMEDOUT` (Kornel Lesiński)
|
||
- More descriminant CommonJS module environment detection.
|
||
- Dropped continuous integration for Node.js 0.6 and 0.8 because of
|
||
changes to npm that preclude the use of new `^` version predicate
|
||
operator in any transitive dependency.
|
||
- Users can now override `Q.nextTick`.
|
||
|
||
## 1.0.1
|
||
|
||
- Adds support for `Q.Promise`, which implements common usage of the
|
||
ES6 `Promise` constructor and its methods. `Promise` does not have
|
||
a valid promise constructor and a proper implementation awaits
|
||
version 2 of Q.
|
||
- Removes the console stopgap for a promise inspector. This no longer
|
||
works with any degree of reliability.
|
||
- Fixes support for content security policies that forbid eval. Now
|
||
using the `StopIteration` global to distinguish SpiderMonkey
|
||
generators from ES6 generators, assuming that they will never
|
||
coexist.
|
||
|
||
## 1.0.0
|
||
|
||
:cake: This is all but a re-release of version 0.9, which has settled
|
||
into a gentle maintenance mode and rightly deserves an official 1.0.
|
||
An ambitious 2.0 release is already around the corner, but 0.9/1.0
|
||
have been distributed far and wide and demand long term support.
|
||
|
||
- Q will now attempt to post a debug message in browsers regardless
|
||
of whether window.Touch is defined. Chrome at least now has this
|
||
property regardless of whether touch is supported by the underlying
|
||
hardware.
|
||
- Remove deprecation warning from `promise.valueOf`. The function is
|
||
called by the browser in various ways so there is no way to
|
||
distinguish usage that should be migrated from usage that cannot be
|
||
altered.
|
||
|
||
## 0.9.7
|
||
|
||
- :warning: `q.min.js` is no longer checked-in. It is however still
|
||
created by Grunt and NPM.
|
||
- Fixes a bug that inhibited `Q.async` with implementations of the new
|
||
ES6 generators.
|
||
- Fixes a bug with `nextTick` affecting Safari 6.0.5 the first time a
|
||
page loads when an `iframe` is involved.
|
||
- Introduces `passByCopy`, `join`, and `race`.
|
||
- Shows stack traces or error messages on the console, instead of
|
||
`Error` objects.
|
||
- Elimintates wrapper methods for improved performance.
|
||
- `Q.all` now propagates progress notifications of the form you might
|
||
expect of ES6 iterations, `{value, index}` where the `value` is the
|
||
progress notification from the promise at `index`.
|
||
|
||
## 0.9.6
|
||
|
||
- Fixes a bug in recognizing the difference between compatible Q
|
||
promises, and Q promises from before the implementation of "inspect".
|
||
The latter are now coerced.
|
||
- Fixes an infinite asynchronous coercion cycle introduced by former
|
||
solution, in two independently sufficient ways. 1.) All promises
|
||
returned by makePromise now implement "inspect", albeit a default
|
||
that reports that the promise has an "unknown" state. 2.) The
|
||
implementation of "then/when" is now in "then" instead of "when", so
|
||
that the responsibility to "coerce" the given promise rests solely in
|
||
the "when" method and the "then" method may assume that "this" is a
|
||
promise of the right type.
|
||
- Refactors `nextTick` to use an unrolled microtask within Q regardless
|
||
of how new ticks a requested. #316 @rkatic
|
||
|
||
## 0.9.5
|
||
|
||
- Introduces `inspect` for getting the state of a promise as
|
||
`{state: "fulfilled" | "rejected" | "pending", value | reason}`.
|
||
- Introduces `allSettled` which produces an array of promises states
|
||
for the input promises once they have all "settled". This is in
|
||
accordance with a discussion on Promises/A+ that "settled" refers to
|
||
a promise that is "fulfilled" or "rejected". "resolved" refers to a
|
||
deferred promise that has been "resolved" to another promise,
|
||
"sealing its fate" to the fate of the successor promise.
|
||
- Long stack traces are now off by default. Set `Q.longStackSupport`
|
||
to true to enable long stack traces.
|
||
- Long stack traces can now follow the entire asynchronous history of a
|
||
promise, not just a single jump.
|
||
- Introduces `spawn` for an immediately invoked asychronous generator.
|
||
@jlongster
|
||
- Support for *experimental* synonyms `mapply`, `mcall`, `nmapply`,
|
||
`nmcall` for method invocation.
|
||
|
||
## 0.9.4
|
||
|
||
- `isPromise` and `isPromiseAlike` now always returns a boolean
|
||
(even for falsy values). #284 @lfac-pt
|
||
- Support for ES6 Generators in `async` #288 @andywingo
|
||
- Clear duplicate promise rejections from dispatch methods #238 @SLaks
|
||
- Unhandled rejection API #296 @domenic
|
||
`stopUnhandledRejectionTracking`, `getUnhandledReasons`,
|
||
`resetUnhandledRejections`.
|
||
|
||
## 0.9.3
|
||
|
||
- Add the ability to give `Q.timeout`'s errors a custom error message. #270
|
||
@jgrenon
|
||
- Fix Q's call-stack busting behavior in Node.js 0.10, by switching from
|
||
`process.nextTick` to `setImmediate`. #254 #259
|
||
- Fix Q's behavior when used with the Mocha test runner in the browser, since
|
||
Mocha introduces a fake `process` global without a `nextTick` property. #267
|
||
- Fix some, but not all, cases wherein Q would give false positives in its
|
||
unhandled rejection detection (#252). A fix for other cases (#238) is
|
||
hopefully coming soon.
|
||
- Made `Q.promise` throw early if given a non-function.
|
||
|
||
## 0.9.2
|
||
|
||
- Pass through progress notifications when using `timeout`. #229 @omares
|
||
- Pass through progress notifications when using `delay`.
|
||
- Fix `nbind` to actually bind the `thisArg`. #232 @davidpadbury
|
||
|
||
## 0.9.1
|
||
|
||
- Made the AMD detection compatible with the RequireJS optimizer's `namespace`
|
||
option. #225 @terinjokes
|
||
- Fix side effects from `valueOf`, and thus from `isFulfilled`, `isRejected`,
|
||
and `isPending`. #226 @benjamn
|
||
|
||
## 0.9.0
|
||
|
||
This release removes many layers of deprecated methods and brings Q closer to
|
||
alignment with Mark Miller’s TC39 [strawman][] for concurrency. At the same
|
||
time, it fixes many bugs and adds a few features around error handling. Finally,
|
||
it comes with an updated and comprehensive [API Reference][].

|

|
||
(*) Use of ``thisp`` is discouraged. For calling methods, use ``post`` or
|
||
``invoke``.
|
||
|
||
### Alignment with the Concurrency Strawman
|
||
|
||
- Q now exports a `Q(value)` function, an alias for `resolve`.
|
||
`Q.call`, `Q.apply`, and `Q.bind` were removed to make room for the
|
||
same methods on the function prototype.
|
||
- `invoke` has been aliased to `send` in all its forms.
|
||
- `post` with no method name acts like `fapply`.
|
||
|
||
### Error Handling
|
||
|
||
- Long stack traces can be turned off by setting `Q.stackJumpLimit` to zero.
|
||
In the future, this property will be used to fine tune how many stack jumps
|
||
are retained in long stack traces; for now, anything nonzero is treated as
|
||
one (since Q only tracks one stack jump at the moment, see #144). #168
|
||
- In Node.js, if there are unhandled rejections when the process exits, they
|
||
are output to the console. #115
|
||
|
||
### Other
|
||
|
||
- `delete` and `set` (née `put`) no longer have a fulfillment value.
|
||
- Q promises are no longer frozen, which
|
||
[helps with performance](http://code.google.com/p/v8/issues/detail?id=1858).
|
||
- `thenReject` is now included, as a counterpart to `thenResolve`.
|
||
- The included browser `nextTick` shim is now faster. #195 @rkatic.
|
||
|
||
### Bug Fixes
|
||
|
||
- Q now works in Internet Explorer 10. #186 @ForbesLindesay
|
||
- `fbind` no longer hard-binds the returned function's `this` to `undefined`.
|
||
#202
|
||
- `Q.reject` no longer leaks memory. #148
|
||
- `npost` with no arguments now works. #207
|
||
- `allResolved` now works with non-Q promises ("thenables"). #179
|
||
- `keys` behavior is now correct even in browsers without native
|
||
`Object.keys`. #192 @rkatic
|
||
- `isRejected` and the `exception` property now work correctly if the
|
||
rejection reason is falsy. #198
|
||
|
||
### Internals and Advanced
|
||
|
||
- The internal interface for a promise now uses
|
||
`dispatchPromise(resolve, op, operands)` instead of `sendPromise(op,
|
||
resolve, ...operands)`, which reduces the cases where Q needs to do
|
||
argument slicing.
|
||
- The internal protocol uses different operands. "put" is now "set".
|
||
"del" is now "delete". "view" and "viewInfo" have been removed.
|
||
- `Q.fulfill` has been added. It is distinct from `Q.resolve` in that
|
||
it does not pass promises through, nor coerces promises from other
|
||
systems. The promise becomes the fulfillment value. This is only
|
||
recommended for use when trying to fulfill a promise with an object that has
|
||
a `then` function that is at the same time not a promise.
|
||
|
||
## 0.8.12
|
||
- Treat foreign promises as unresolved in `Q.isFulfilled`; this lets `Q.all`
|
||
work on arrays containing foreign promises. #154
|
||
- Fix minor incompliances with the [Promises/A+ spec][] and [test suite][]. #157
|
||
#158
|
||
|
||
[Promises/A+ spec]: http://promises-aplus.github.com/promises-spec/
|
||
[test suite]: https://github.com/promises-aplus/promises-tests
|
||
|
||
## 0.8.11
|
||
|
||
- Added ``nfcall``, ``nfapply``, and ``nfbind`` as ``thisp``-less versions of
|
||
``ncall``, ``napply``, and ``nbind``. The latter are now deprecated. #142
|
||
- Long stack traces no longer cause linearly-growing memory usage when chaining
|
||
promises together. #111
|
||
- Inspecting ``error.stack`` in a rejection handler will now give a long stack
|
||
trace. #103
|
||
- Fixed ``Q.timeout`` to clear its timeout handle when the promise is rejected;
|
||
previously, it kept the event loop alive until the timeout period expired.
|
||
#145 @dfilatov
|
||
- Added `q/queue` module, which exports an infinite promise queue
|
||
constructor.
|
||
|
||
## 0.8.10
|
||
|
||
- Added ``done`` as a replacement for ``end``, taking the usual fulfillment,
|
||
rejection, and progress handlers. It's essentially equivalent to
|
||
``then(f, r, p).end()``.
|
||
- Added ``Q.onerror``, a settable error trap that you can use to get full stack
|
||
traces for uncaught errors. #94
|
||
- Added ``thenResolve`` as a shortcut for returning a constant value once a
|
||
promise is fulfilled. #108 @ForbesLindesay
|
||
- Various tweaks to progress notification, including propagation and
|
||
transformation of progress values and only forwarding a single progress
|
||
object.
|
||
- Renamed ``nend`` to ``nodeify``. It no longer returns an always-fulfilled
|
||
promise when a Node callback is passed.
|
||
- ``deferred.resolve`` and ``deferred.reject`` no longer (sometimes) return
|
||
``deferred.promise``.
|
||
- Fixed stack traces getting mangled if they hit ``end`` twice. #116 #121 @ef4
|
||
- Fixed ``ninvoke`` and ``npost`` to work on promises for objects with Node
|
||
methods. #134
|
||
- Fixed accidental coercion of objects with nontrivial ``valueOf`` methods,
|
||
like ``Date``s, by the promise's ``valueOf`` method. #135
|
||
- Fixed ``spread`` not calling the passed rejection handler if given a rejected
|
||
promise.
|
||
|
||
## 0.8.9
|
||
|
||
- Added ``nend``
|
||
- Added preliminary progress notification support, via
|
||
``promise.then(onFulfilled, onRejected, onProgress)``,
|
||
``promise.progress(onProgress)``, and ``deferred.notify(...progressData)``.
|
||
- Made ``put`` and ``del`` return the object acted upon for easier chaining.
|
||
#84
|
||
- Fixed coercion cycles with cooperating promises. #106
|
||
|
||
## 0.8.7
|
||
|
||
- Support [Montage Require](http://github.com/kriskowal/mr)
|
||
|
||
## 0.8.6
|
||
|
||
- Fixed ``npost`` and ``ninvoke`` to pass the correct ``thisp``. #74
|
||
- Fixed various cases involving unorthodox rejection reasons. #73 #90
|
||
@ef4
|
||
- Fixed double-resolving of misbehaved custom promises. #75
|
||
- Sped up ``Q.all`` for arrays contain already-resolved promises or scalar
|
||
values. @ForbesLindesay
|
||
- Made stack trace filtering work when concatenating assets. #93 @ef4
|
||
- Added warnings for deprecated methods. @ForbesLindesay
|
||
- Added ``.npmignore`` file so that dependent packages get a slimmer
|
||
``node_modules`` directory.
|
||
|
||
## 0.8.5
|
||
|
||
- Added preliminary support for long traces (@domenic)
|
||
- Added ``fapply``, ``fcall``, ``fbind`` for non-thisp
|
||
promised function calls.
|
||
- Added ``return`` for async generators, where generators
|
||
are implemented.
|
||
- Rejected promises now have an "exception" property. If an object
|
||
isRejected(object), then object.valueOf().exception will
|
||
be the wrapped error.
|
||
- Added Jasmine specifications
|
||
- Support Internet Explorers 7–9 (with multiple bug fixes @domenic)
|
||
- Support Firefox 12
|
||
- Support Safari 5.1.5
|
||
- Support Chrome 18
|
||
|
||
## 0.8.4
|
||
|
||
- WARNING: ``promise.timeout`` is now rejected with an ``Error`` object
|
||
and the message now includes the duration of the timeout in
|
||
miliseconds. This doesn't constitute (in my opinion) a
|
||
backward-incompatibility since it is a change of an undocumented and
|
||
unspecified public behavior, but if you happened to depend on the
|
||
exception being a string, you will need to revise your code.
|
||
- Added ``deferred.makeNodeResolver()`` to replace the more cryptic
|
||
``deferred.node()`` method.
|
||
- Added experimental ``Q.promise(maker(resolve, reject))`` to make a
|
||
promise inside a callback, such that thrown exceptions in the
|
||
callback are converted and the resolver and rejecter are arguments.
|
||
This is a shorthand for making a deferred directly and inspired by
|
||
@gozala’s stream constructor pattern and the Microsoft Windows Metro
|
||
Promise constructor interface.
|
||
- Added experimental ``Q.begin()`` that is intended to kick off chains
|
||
of ``.then`` so that each of these can be reordered without having to
|
||
edit the new and former first step.
|
||
|
||
## 0.8.3
|
||
|
||
- Added ``isFulfilled``, ``isRejected``, and ``isResolved``
|
||
to the promise prototype.
|
||
- Added ``allResolved`` for waiting for every promise to either be
|
||
fulfilled or rejected, without propagating an error. @utvara #53
|
||
- Added ``Q.bind`` as a method to transform functions that
|
||
return and throw into promise-returning functions. See
|
||
[an example](https://gist.github.com/1782808). @domenic
|
||
- Renamed ``node`` export to ``nbind``, and added ``napply`` to
|
||
complete the set. ``node`` remains as deprecated. @domenic #58
|
||
- Renamed ``Method`` export to ``sender``. ``Method``
|
||
remains as deprecated and will be removed in the next
|
||
major version since I expect it has very little usage.
|
||
- Added browser console message indicating a live list of
|
||
unhandled errors.
|
||
- Added support for ``msSetImmediate`` (IE10) or ``setImmediate``
|
||
(available via [polyfill](https://github.com/NobleJS/setImmediate))
|
||
as a browser-side ``nextTick`` implementation. #44 #50 #59
|
||
- Stopped using the event-queue dependency, which was in place for
|
||
Narwhal support: now directly using ``process.nextTick``.
|
||
- WARNING: EXPERIMENTAL: added ``finally`` alias for ``fin``, ``catch``
|
||
alias for ``fail``, ``try`` alias for ``call``, and ``delete`` alias
|
||
for ``del``. These properties are enquoted in the library for
|
||
cross-browser compatibility, but may be used as property names in
|
||
modern engines.
|
||
|
||
## 0.8.2
|
||
|
||
- Deprecated ``ref`` in favor of ``resolve`` as recommended by
|
||
@domenic.
|
||
- Update event-queue dependency.
|
||
|
||
## 0.8.1
|
||
|
||
- Fixed Opera bug. #35 @cadorn
|
||
- Fixed ``Q.all([])`` #32 @domenic
|
||
|
||
## 0.8.0
|
||
|
||
- WARNING: ``enqueue`` removed. Use ``nextTick`` instead.
|
||
This is more consistent with NodeJS and (subjectively)
|
||
more explicit and intuitive.
|
||
- WARNING: ``def`` removed. Use ``master`` instead. The
|
||
term ``def`` was too confusing to new users.
|
||
- WARNING: ``spy`` removed in favor of ``fin``.
|
||
- WARNING: ``wait`` removed. Do ``all(args).get(0)`` instead.
|
||
- WARNING: ``join`` removed. Do ``all(args).spread(callback)`` instead.
|
||
- WARNING: Removed the ``Q`` function module.exports alias
|
||
for ``Q.ref``. It conflicts with ``Q.apply`` in weird
|
||
ways, making it uncallable.
|
||
- Revised ``delay`` so that it accepts both ``(value,
|
||
timeout)`` and ``(timeout)`` variations based on
|
||
arguments length.
|
||
- Added ``ref().spread(cb(...args))``, a variant of
|
||
``then`` that spreads an array across multiple arguments.
|
||
Useful with ``all()``.
|
||
- Added ``defer().node()`` Node callback generator. The
|
||
callback accepts ``(error, value)`` or ``(error,
|
||
...values)``. For multiple value arguments, the
|
||
fulfillment value is an array, useful in conjunction with
|
||
``spread``.
|
||
- Added ``node`` and ``ncall``, both with the signature
|
||
``(fun, thisp_opt, ...args)``. The former is a decorator
|
||
and the latter calls immediately. ``node`` optional
|
||
binds and partially applies. ``ncall`` can bind and pass
|
||
arguments.
|
||
|
||
## 0.7.2
|
||
|
||
- Fixed thenable promise assimilation.
|
||
|
||
## 0.7.1
|
||
|
||
- Stopped shimming ``Array.prototype.reduce``. The
|
||
enumerable property has bad side-effects. Libraries that
|
||
depend on this (for example, QQ) will need to be revised.
|
||
|
||
## 0.7.0 - BACKWARD INCOMPATIBILITY
|
||
|
||
- WARNING: Removed ``report`` and ``asap``
|
||
- WARNING: The ``callback`` argument of the ``fin``
|
||
function no longer receives any arguments. Thus, it can
|
||
be used to call functions that should not receive
|
||
arguments on resolution. Use ``when``, ``then``, or
|
||
``fail`` if you need a value.
|
||
- IMPORTANT: Fixed a bug in the use of ``MessageChannel``
|
||
for ``nextTick``.
|
||
- Renamed ``enqueue`` to ``nextTick``.
|
||
- Added experimental ``view`` and ``viewInfo`` for creating
|
||
views of promises either when or before they're
|
||
fulfilled.
|
||
- Shims are now externally applied so subsequent scripts or
|
||
dependees can use them.
|
||
- Improved minification results.
|
||
- Improved readability.
|
||
|
||
## 0.6.0 - BACKWARD INCOMPATIBILITY
|
||
|
||
- WARNING: In practice, the implementation of ``spy`` and
|
||
the name ``fin`` were useful. I've removed the old
|
||
``fin`` implementation and renamed/aliased ``spy``.
|
||
- The "q" module now exports its ``ref`` function as a "Q"
|
||
constructor, with module systems that support exports
|
||
assignment including NodeJS, RequireJS, and when used as
|
||
a ``<script>`` tag. Notably, strictly compliant CommonJS
|
||
does not support this, but UncommonJS does.
|
||
- Added ``async`` decorator for generators that use yield
|
||
to "trampoline" promises. In engines that support
|
||
generators (SpiderMonkey), this will greatly reduce the
|
||
need for nested callbacks.
|
||
- Made ``when`` chainable.
|
||
- Made ``all`` chainable.
|
||
|
||
## 0.5.3
|
||
|
||
- Added ``all`` and refactored ``join`` and ``wait`` to use
|
||
it. All of these will now reject at the earliest
|
||
rejection.
|
||
|
||
## 0.5.2
|
||
|
||
- Minor improvement to ``spy``; now waits for resolution of
|
||
callback promise.
|
||
|
||
## 0.5.1
|
||
|
||
- Made most Q API methods chainable on promise objects, and
|
||
turned the previous promise-methods of ``join``,
|
||
``wait``, and ``report`` into Q API methods.
|
||
- Added ``apply`` and ``call`` to the Q API, and ``apply``
|
||
as a promise handler.
|
||
- Added ``fail``, ``fin``, and ``spy`` to Q and the promise
|
||
prototype for convenience when observing rejection,
|
||
fulfillment and rejection, or just observing without
|
||
affecting the resolution.
|
||
- Renamed ``def`` (although ``def`` remains shimmed until
|
||
the next major release) to ``master``.
|
||
- Switched to using ``MessageChannel`` for next tick task
|
||
enqueue in browsers that support it.
|
||
|
||
## 0.5.0 - MINOR BACKWARD INCOMPATIBILITY
|
||
|
||
- Exceptions are no longer reported when consumed.
|
||
- Removed ``error`` from the API. Since exceptions are
|
||
getting consumed, throwing them in an errback causes the
|
||
exception to silently disappear. Use ``end``.
|
||
- Added ``end`` as both an API method and a promise-chain
|
||
ending method. It causes propagated rejections to be
|
||
thrown, which allows Node to write stack traces and
|
||
emit ``uncaughtException`` events, and browsers to
|
||
likewise emit ``onerror`` and log to the console.
|
||
- Added ``join`` and ``wait`` as promise chain functions,
|
||
so you can wait for variadic promises, returning your own
|
||
promise back, or join variadic promises, resolving with a
|
||
callback that receives variadic fulfillment values.
|
||
|
||
## 0.4.4
|
||
|
||
- ``end`` no longer returns a promise. It is the end of the
|
||
promise chain.
|
||
- Stopped reporting thrown exceptions in ``when`` callbacks
|
||
and errbacks. These must be explicitly reported through
|
||
``.end()``, ``.then(null, Q.error)``, or some other
|
||
mechanism.
|
||
- Added ``report`` as an API method, which can be used as
|
||
an errback to report and propagate an error.
|
||
- Added ``report`` as a promise-chain method, so an error
|
||
can be reported if it passes such a gate.
|
||
|
||
## 0.4.3
|
||
|
||
- Fixed ``<script>`` support that regressed with 0.4.2
|
||
because of "use strict" in the module system
|
||
multi-plexer.
|
||
|
||
## 0.4.2
|
||
|
||
- Added support for RequireJS (jburke)
|
||
|
||
## 0.4.1
|
||
|
||
- Added an "end" method to the promise prototype,
|
||
as a shorthand for waiting for the promise to
|
||
be resolved gracefully, and failing to do so,
|
||
to dump an error message.
|
||
|
||
## 0.4.0 - BACKWARD INCOMPATIBLE*
|
||
|
||
- *Removed the utility modules. NPM and Node no longer
|
||
expose any module except the main module. These have
|
||
been moved and merged into the "qq" package.
|
||
- *In a non-CommonJS browser, q.js can be used as a script.
|
||
It now creates a Q global variable.
|
||
- Fixed thenable assimilation.
|
||
- Fixed some issues with asap, when it resolves to
|
||
undefined, or throws an exception.
|
||
|
||
## 0.3.0 - BACKWARD-INCOMPATIBLE
|
||
|
||
- The `post` method has been reverted to its original
|
||
signature, as provided in Tyler Close's `ref_send` API.
|
||
That is, `post` accepts two arguments, the second of
|
||
which is an arbitrary object, but usually invocation
|
||
arguments as an `Array`. To provide variadic arguments
|
||
to `post`, there is a new `invoke` function that posts
|
||
the variadic arguments to the value given in the first
|
||
argument.
|
||
- The `defined` method has been moved from `q` to `q/util`
|
||
since it gets no use in practice but is still
|
||
theoretically useful.
|
||
- The `Promise` constructor has been renamed to
|
||
`makePromise` to be consistent with the convention that
|
||
functions that do not require the `new` keyword to be
|
||
used as constructors have camelCase names.
|
||
- The `isResolved` function has been renamed to
|
||
`isFulfilled`. There is a new `isResolved` function that
|
||
indicates whether a value is not a promise or, if it is a
|
||
promise, whether it has been either fulfilled or
|
||
rejected. The code has been revised to reflect this
|
||
nuance in terminology.
|
||
|
||
## 0.2.10
|
||
|
||
- Added `join` to `"q/util"` for variadically joining
|
||
multiple promises.
|
||
|
||
## 0.2.9
|
||
|
||
- The future-compatible `invoke` method has been added,
|
||
to replace `post`, since `post` will become backward-
|
||
incompatible in the next major release.
|
||
- Exceptions thrown in the callbacks of a `when` call are
|
||
now emitted to Node's `"uncaughtException"` `process`
|
||
event in addition to being returned as a rejection reason.
|
||
|
||
## 0.2.8
|
||
|
||
- Exceptions thrown in the callbacks of a `when` call
|
||
are now consumed, warned, and transformed into
|
||
rejections of the promise returned by `when`.
|
||
|
||
## 0.2.7
|
||
|
||
- Fixed a minor bug in thenable assimilation, regressed
|
||
because of the change in the forwarding protocol.
|
||
- Fixed behavior of "q/util" `deep` method on dates and
|
||
other primitives. Github issue #11.
|
||
|
||
## 0.2.6
|
||
|
||
- Thenables (objects with a "then" method) are accepted
|
||
and provided, bringing this implementation of Q
|
||
into conformance with Promises/A, B, and D.
|
||
- Added `makePromise`, to replace the `Promise` function
|
||
eventually.
|
||
- Rejections are now also duck-typed. A rejection is a
|
||
promise with a valueOf method that returns a rejection
|
||
descriptor. A rejection descriptor has a
|
||
"promiseRejected" property equal to "true" and a
|
||
"reason" property corresponding to the rejection reason.
|
||
- Altered the `makePromise` API such that the `fallback`
|
||
method no longer receives a superfluous `resolved` method
|
||
after the `operator`. The fallback method is responsible
|
||
only for returning a resolution. This breaks an
|
||
undocumented API, so third-party API's depending on the
|
||
previous undocumented behavior may break.
|
||
|
||
## 0.2.5
|
||
|
||
- Changed promises into a duck-type such that multiple
|
||
instances of the Q module can exchange promise objects.
|
||
A promise is now defined as "an object that implements the
|
||
`promiseSend(op, resolved, ...)` method and `valueOf`".
|
||
- Exceptions in promises are now captured and returned
|
||
as rejections.
|
||
|
||
## 0.2.4
|
||
|
||
- Fixed bug in `ref` that prevented `del` messages from
|
||
being received (gozala)
|
||
- Fixed a conflict with FireFox 4; constructor property
|
||
is now read-only.
|
||
|
||
## 0.2.3
|
||
|
||
- Added `keys` message to promises and to the promise API.
|
||
|
||
## 0.2.2
|
||
|
||
- Added boilerplate to `q/queue` and `q/util`.
|
||
- Fixed missing dependency to `q/queue`.
|
||
|
||
## 0.2.1
|
||
|
||
- The `resolve` and `reject` methods of `defer` objects now
|
||
return the resolution promise for convenience.
|
||
- Added `q/util`, which provides `step`, `delay`, `shallow`,
|
||
`deep`, and three reduction orders.
|
||
- Added `q/queue` module for a promise `Queue`.
|
||
- Added `q-comm` to the list of compatible libraries.
|
||
- Deprecated `defined` from `q`, with intent to move it to
|
||
`q/util`.
|
||
|
||
## 0.2.0 - BACKWARD INCOMPATIBLE
|
||
|
||
- Changed post(ref, name, args) to variadic
|
||
post(ref, name, ...args). BACKWARD INCOMPATIBLE
|
||
- Added a def(value) method to annotate an object as being
|
||
necessarily a local value that cannot be serialized, such
|
||
that inter-process/worker/vat promise communication
|
||
libraries will send messages to it, but never send it
|
||
back.
|
||
- Added a send(value, op, ...args) method to the public API, for
|
||
forwarding messages to a value or promise in a future turn.
|
||
|
||
## 0.1.9
|
||
|
||
- Added isRejected() for testing whether a value is a rejected
|
||
promise. isResolved() retains the behavior of stating
|
||
that rejected promises are not resolved.
|
||
|
||
## 0.1.8
|
||
|
||
- Fixed isResolved(null) and isResolved(undefined) [issue #9]
|
||
- Fixed a problem with the Object.create shim
|
||
|
||
## 0.1.7
|
||
|
||
- shimmed ES5 Object.create in addition to Object.freeze
|
||
for compatibility on non-ES5 engines (gozala)
|
||
|
||
## 0.1.6
|
||
|
||
- Q.isResolved added
|
||
- promise.valueOf() now returns the value of resolved
|
||
and near values
|
||
- asap retried
|
||
- promises are frozen when possible
|
||
|
||
## 0.1.5
|
||
|
||
- fixed dependency list for Teleport (gozala)
|
||
- all unit tests now pass (gozala)
|
||
|
||
## 0.1.4
|
||
|
||
- added support for Teleport as an engine (gozala)
|
||
- simplified and updated methods for getting internal
|
||
print and enqueue functions universally (gozala)
|
||
|
||
## 0.1.3
|
||
|
||
- fixed erroneous link to the q module in package.json
|
||
|
||
## 0.1.2
|
||
|
||
- restructured for overlay style package compatibility
|
||
|
||
## 0.1.0
|
||
|
||
- removed asap because it was broken, probably down to the
|
||
philosophy.
|
||
|
||
## 0.0.3
|
||
|
||
- removed q-util
|
||
- fixed asap so it returns a value if completed
|
||
|
||
## 0.0.2
|
||
|
||
- added q-util
|
||
|
||
## 0.0.1
|
||
|
||
- initial version
|
