According to the documentation for the child_process module, process.send() should block. It seems that this is no longer the case in v1.1.0.

//parent.js

var fork = require('child_process').fork;
var child = fork('./child.js');
child.on('message', function (m) {
    console.log('got message from child: ' + m);
});

//child.js

process.send(new Buffer(2048));
process.exit(0);

In this example, if the child process attempts to send a sufficiently large object to the parent, the child process exits but does not send all of the data. However, smaller messages (perhaps a Buffer of 1024 bytes) are successfully sent.

I think this change in functionality was introduced in 07bd05b when uv__nonblock() was added to uv_pipe_open() in deps/uv/src/unix/pipe.c. Removing the call to uv__nonblock() restores the original behavior of process.send().

I ran into this issue on OSX 10.10.2 LLVM 6.0 (clang-600.0.56), if it helps.

Running also on OSX, I can confirm that this indeed happens - for me, 2048 sends but 4096 does not. This is noted in the documentation:

Please note that the send() method on both the parent and child are synchronous - sending large chunks of data is not advised (pipes can be used instead, see child_process.spawn).

Running on node v0.11.14, all the data up to 16384 was sent on my machine.

Thanks for confirming. When I read the documentation, I figured that it was an advisory about the blocking nature of send() and the resulting performance impact, but not that there is a restriction on how much data can be sent in a single synchronous call. With node v0.12.0 I'm able to send back megabytes of data to the parent process.

If I remove the call to process.exit() in my example, all of the data is transmitted. This leads me to believe that during the initial call to process.send(), a portion of the data is sent to the parent process, but the rest is placed into the event queue to be sent later. process.exit() then terminates the child process without allowing the rest of the queued data to be sent.

Looks like as per libuv/libuv#393c1c5:

the file descriptor should already be in non-blocking mode before passing it to libuv

Which, I think to set it into non-blocking mode (or blocking in this case), you have to call pipe.setBlocking(), which would have to be done here.

Of course, when I change that, it doesn't fix the issue for me, but I'll leave my work here in case anyone wants to build off that.

FWIW, setBlocking probably calls uv_stream_set_blocking, which is only implemented on Windows and only for named pipes.

Commit 393c1c5 ("unix: set non-block mode in uv_{pipe,tcp,udp}_open")
causes a regression in the io.js cluster module.

The io.js documentation states that `worker.send()` and `process.send()`
are synchronous but they no longer were after upgrading to libuv v1.2.1.

The reason they are synchronous is because of backpressure - or rather,
lack of backpressure: a slow consumer eventually causes a fast producer
to run out of memory because the backlog of pending messages in the
producer can grow unchecked.

Ergo, implement uv_stream_set_blocking() on UNIX platforms to let io.js
enable the old blocking behavior for pipes again.

process.send() should be synchronous, it should block until the message
has been sent in full, but it wasn't after the second-to-last libuv
upgrade because of commit libuv/libuv@393c1c5 ("unix: set non-block
mode in uv_{pipe,tcp,udp}_open"), which made its way into io.js in
commit 07bd05b ("deps: update libuv to 1.2.1").

Commit libuv/libuv@b36d4ff ("unix: implement uv_stream_set_blocking()")
as landed in io.js in commit 9681fca ("deps: update libuv to 1.4.0")
makes it possible to restore the synchronous behavior again and that's
precisely what this commit does.

The same line of reasoning applies to `net.Socket({ fd: 1 })`: creating
a socket object from a stdio file descriptor, like the `process.stdout`
getter does, should put the file descriptor in blocking mode for
compatibility reasons.

Current status: (#774 (comment))

I think I'd rather take a different approach and make the asynchronous nature of process.send() official.

We'd need a docs pr then I think, but this may be rediscussed as per #34

Can someone summarize how process.send behaves in io.js today? If it uses non blocking pipes, it should be documented as such and if it waits until the process receives the data, too. Also, I wonder if there are now OS differences in the way this works.

Moving discussion from nodejs/node-convergence-archive#34 and added to 4.0.0 milestone.

@bnoordhuis @piscisaureus what are the chances of getting a change in that would unify asynchronous behaviour across platforms within the next week or so? Are we going to have to punt this till 5.0.0 and if so, how painful will that be for users of v4 as it heads in to LTS?

@bnoordhuis can I get you to take responsibility for doing something about sync/async send() this week please? Your latest comment in nodejs/node-convergence-archive#34 was that you thought making sure it's async on all platforms was the way to go and therefore documentation should note this. I'd lgtm any PR that takes this off our known issues list, no matter which way it falls.

Add an optional callback parameter to `ChildProcess.prototype.send()`

Juggle the control channel's reference count so that in-flight messages
keep the event loop (and therefore the process) alive until they have
been sent.

Changelog:
## 2015-09-08, Version 4.0.0 (Stable), @rvagg

### Notable changes

This list of changes is relative to the last io.js v3.x branch release, v3.3.0. Please see the list of notable changes in the v3.x, v2.x and v1.x releases for a more complete list of changes from 0.12.x. Note, that some changes in the v3.x series as well as major breaking changes in this release constitute changes required for full convergence of the Node.js and io.js projects.

* **child_process**: `ChildProcess.prototype.send()` and `process.send()` operate asynchronously across all platforms so an optional callback parameter has been introduced that will be invoked once the message has been sent, i.e. `.send(message[, sendHandle][, callback])` (Ben Noordhuis) [#2620](https://github.com/nodejs/node/pull/2620).
* **node**: Rename "io.js" code to "Node.js" (cjihrig) [#2367](https://github.com/nodejs/node/pull/2367).
* **node-gyp**: This release bundles an updated version of node-gyp that works with all versions of Node.js and io.js including nightly and release candidate builds. From io.js v3 and Node.js v4 onward, it will only download a headers tarball when building addons rather than the entire source. (Rod Vagg) [#2700](https://github.com/nodejs/node/pull/2700)
* **npm**: Upgrade to version 2.14.2 from 2.13.3, includes a security update, see https://github.com/npm/npm/releases/tag/v2.14.2 for more details, (Kat Marchán) [#2696](https://github.com/nodejs/node/pull/2696).
* **timers**: Improved timer performance from porting the 0.12 implementation, plus minor fixes (Jeremiah Senkpiel) [#2540](https://github.com/nodejs/node/pull/2540), (Julien Gilli) [nodejs/node-v0.x-archive#8751](https://github.com/nodejs/node-v0.x-archive/pull/8751) [nodejs/node-v0.x-archive#8905](https://github.com/nodejs/node-v0.x-archive/pull/8905)
* **util**: The `util.is*()` functions have been deprecated, beginning with deprecation warnings in the documentation for this release, users are encouraged to seek more robust alternatives in the npm registry, (Sakthipriyan Vairamani) [#2447](https://github.com/nodejs/node/pull/2447).
* **v8**: Upgrade to version 4.5.103.30 from 4.4.63.30 (Ali Ijaz Sheikh) [#2632](https://github.com/nodejs/node/pull/2632).
 - Implement new `TypedArray` prototype methods: `copyWithin()`, `every()`, `fill()`, `filter()`, `find()`, `findIndex()`, `forEach()`, `indexOf()`, `join()`, `lastIndexOf()`, `map()`, `reduce()`, `reduceRight()`, `reverse()`, `slice()`, `some()`, `sort()`. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray for further information.
 - Implement new `TypedArray.from()` and `TypedArray.of()` functions. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray for further information.
 - Implement arrow functions, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions for further information.

### Known issues

See https://github.com/nodejs/node/labels/confirmed-bug for complete and current list of known issues.

* Some uses of computed object shorthand properties are not handled correctly by the current version of V8. e.g. `[{ [prop]: val }]` evaluates to `[{}]`. [#2507](https://github.com/nodejs/node/issues/2507)
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/node/issues/1264).
* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/node/issues/690)
* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/node/issues/894)
* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/node/issues/1435).

## 2015-09-02, Version 3.3.0, @rvagg

### Notable changes

* **build**: Add a `--link-module` option to `configure` that can be used to bundle additional JavaScript modules into a built binary (Bradley Meck) [#2497](https://github.com/nodejs/node/pull/2497)
* **docs**: Merge outstanding doc updates from joyent/node (James M Snell) [#2378](https://github.com/nodejs/node/pull/2378)
* **http_parser**: Significant performance improvement by having `http.Server` consume all initial data from its `net.Socket` and parsing directly without having to enter JavaScript. Any `'data'` listeners on the `net.Socket` will result in the data being "unconsumed" into JavaScript, thereby undoing any performance gains. (Fedor Indutny) [#2355](https://github.com/nodejs/node/pull/2355)
* **libuv**: Upgrade to 1.7.3 (from 1.6.1), see [ChangeLog](https://github.com/libuv/libuv/blob/v1.x/ChangeLog) for details (Saúl Ibarra Corretgé) [#2310](https://github.com/nodejs/node/pull/2310)
* **V8**: Upgrade to 4.4.63.30 (from 4.4.63.26) (Michaël Zasso) [#2482](https://github.com/nodejs/node/pull/2482)

### Known issues

See https://github.com/nodejs/io.js/labels/confirmed-bug for complete and current list of known issues.

* Some uses of computed object shorthand properties are not handled correctly by the current version of V8. e.g. `[{ [prop]: val }]` evaluates to `[{}]`. [#2507](https://github.com/nodejs/node/issues/2507)
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/io.js/issues/1264).
* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/io.js/issues/690)
* `process.send()` is not synchronous as the docs suggest, a regression introduced in 1.0.2, see [#760](https://github.com/nodejs/io.js/issues/760).
* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/io.js/issues/894)
* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/io.js/issues/1435).

## 2015-08-25, Version 3.2.0, @rvagg

### Notable changes

* **events**: Added `EventEmitter#listenerCount(event)` as a replacement for `EventEmitter.listenerCount(emitter, event)`, which has now been marked as deprecated in the docs. (Sakthipriyan Vairamani) [#2349](https://github.com/nodejs/node/pull/2349)
* **module**: Fixed an error with preloaded modules when the current working directory doesn't exist. (Bradley Meck) [#2353](https://github.com/nodejs/node/pull/2353)
* **node**: Startup time is now about 5% faster when not passing V8 flags. (Evan Lucas) [#2483](https://github.com/nodejs/node/pull/2483)
* **repl**: Tab-completion now works better with arrays. (James M Snell) [#2409](https://github.com/nodejs/node/pull/2409)
* **string_bytes**: Fixed an unaligned write in the handling of UCS2 encoding. (Fedor Indutny) [#2480](https://github.com/nodejs/node/pull/2480)
* **tls**: Added a new `--tls-cipher-list` flag that can be used to override the built-in default cipher list. (James M Snell) [#2412](https://github.com/nodejs/node/pull/2412) _Note: it is suggested you use the built-in cipher list as it has been carefully selected to reflect current security best practices and risk mitigation._

### Known issues

See https://github.com/nodejs/io.js/labels/confirmed-bug for complete and current list of known issues.

* Some uses of computed object shorthand properties are not handled correctly by the current version of V8. e.g. `[{ [prop]: val }]` evaluates to `[{}]`. [#2507](https://github.com/nodejs/node/issues/2507)
* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/io.js/issues/1264).
* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/io.js/issues/690)
* `process.send()` is not synchronous as the docs suggest, a regression introduced in 1.0.2, see [#760](https://github.com/nodejs/io.js/issues/760).
* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/io.js/issues/894)
* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/io.js/issues/1435).

## 2015-08-18, Version 3.1.0, @Fishrock123

### Notable changes

* **buffer**: Fixed a couple large memory leaks (Ben Noordhuis) [#2352](https://github.com/nodejs/node/pull/2352).
* **crypto**:
  - Fixed a couple of minor memory leaks (Karl Skomski) [#2375](https://github.com/nodejs/node/pull/2375).
  - Signing now checks for OpenSSL errors (P.S.V.R) [#2342](https://github.com/nodejs/node/pull/2342). **Note that this may expose previously hidden errors in user code.**
* **intl**: Intl support using small-icu is now enabled by default in builds (Steven R. Loomis) [#2264](https://github.com/nodejs/node/pull/2264).
  - [`String#normalize()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/normalize) can now be used for unicode normalization.
  - The [`Intl`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Intl) object and various `String` and `Number` methods are present, but only support the English locale.
  - For support of all locales, node must be built with [full-icu](https://github.com/nodejs/node#build-with-full-icu-support-all-locales-supported-by-icu).
* **tls**: Fixed tls throughput being much lower after an incorrect merge (Fedor Indutny) [#2381](https://github.com/nodejs/node/pull/2381).
* **tools**: The v8 tick processor now comes bundled with node (Matt Loring) [#2090](https://github.com/nodejs/node/pull/2090).
  - This can be used by producing performance profiling output by running node with `--perf`, then running your appropriate platform's script on the output as found in [tools/v8-prof](https://github.com/nodejs/node/tree/master/tools/v8-prof).
* **util**: `util.inspect(obj)` now prints the constructor name of the object if there is one (Christopher Monsanto) [#1935](https://github.com/nodejs/io.js/pull/1935).

### Known issues

See https://github.com/nodejs/io.js/labels/confirmed-bug for complete and current list of known issues.

* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/io.js/issues/1264).
* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/io.js/issues/690)
* `process.send()` is not synchronous as the docs suggest, a regression introduced in 1.0.2, see [#760](https://github.com/nodejs/io.js/issues/760).
* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/io.js/issues/894)
* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/io.js/issues/1435).

## 2015-08-04, Version 3.0.0, @rvagg

### Notable changes

* **buffer**:
  - Due to changes in V8, it has been necessary to reimplement `Buffer` on top of V8's `Uint8Array`. Every effort has been made to minimize the performance impact, however `Buffer` instantiation is measurably slower. Access operations may be faster in some circumstances but the exact performance profile and difference over previous versions will depend on how `Buffer` is used within applications. (Trevor Norris) [#1825](https://github.com/nodejs/node/pull/1825).
  - `Buffer` can now take `ArrayBuffer`s as a constructor argument (Trevor Norris) [#2002](https://github.com/nodejs/node/pull/2002).
  - When a single buffer is passed to `Buffer.concat()`, a new, copied `Buffer` object will be returned; previous behavior was to return the original `Buffer` object (Sakthipriyan Vairamani) [#1937](https://github.com/nodejs/node/pull/1937).
* **build**: PPC support has been added to core to allow compiling on pLinux BE and LE (AIX support coming soon) (Michael Dawson) [#2124](https://github.com/nodejs/node/pull/2124).
* **dgram**: If an error occurs within `socket.send()` and a callback has been provided, the error is only passed as the first argument to the callback and not emitted on the `socket` object; previous behavior was to do both (Matteo Collina & Chris Dickinson) [#1796](https://github.com/nodejs/node/pull/1796)
* **freelist**: Deprecate the undocumented `freelist` core module (Sakthipriyan Vairamani) [#2176](https://github.com/nodejs/node/pull/2176).
* **http**:
  - Status codes now all use the official [IANA names](http://www.iana.org/assignments/http-status-codes) as per [RFC7231](https://tools.ietf.org/html/rfc7231), e.g. `http.STATUS_CODES[414]` now returns `'URI Too Long'` rather than `'Request-URI Too Large'` (jomo) [#1470](https://github.com/nodejs/node/pull/1470).
  - Calling .getName() on an HTTP agent no longer returns a trailing colon, HTTPS agents will no longer return an extra colon near the middle of the string (Brendan Ashworth) [#1617](https://github.com/nodejs/node/pull/1617).
* **node**:
  - `NODE_MODULE_VERSION` has been bumped to `45` to reflect the break in ABI (Rod Vagg) [#2096](https://github.com/nodejs/node/pull/2096).
  - Introduce a new `process.release` object that contains a `name` property set to `'io.js'` and `sourceUrl`, `headersUrl` and `libUrl` (Windows only) properties containing URLs for the relevant resources; this is intended to be used by node-gyp (Rod Vagg) [#2154](https://github.com/nodejs/node/pull/2154).
  - The version of node-gyp bundled with io.js now downloads and uses a tarball of header files from iojs.org rather than the full source for compiling native add-ons; it is hoped this is a temporary floating patch and the change will be upstreamed to node-gyp soon (Rod Vagg) [#2066](https://github.com/nodejs/node/pull/2066).
* **repl**: Persistent history is now enabled by default. The history file is located at ~/.node_repl_history, which can be overridden by the new environment variable `NODE_REPL_HISTORY`. This deprecates the previous `NODE_REPL_HISTORY_FILE` variable. Additionally, the format of the file has been changed to plain text to better handle file corruption. (Jeremiah Senkpiel) [#2224](https://github.com/nodejs/node/pull/2224).
* **smalloc**: The `smalloc` module has been removed as it is no longer possible to provide the API due to changes in V8 (Ben Noordhuis) [#2022](https://github.com/nodejs/node/pull/2022).
* **tls**: Add `server.getTicketKeys()` and `server.setTicketKeys()` methods for [TLS session key](https://www.ietf.org/rfc/rfc5077.txt) rotation (Fedor Indutny) [#2227](https://github.com/nodejs/node/pull/2227).
* **v8**: Upgraded to 4.4.63.26
  - ES6: Enabled [computed property names](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#Computed_property_names)
  - ES6: `Array` can now be subclassed in strict mode
  - ES6: Implement [rest parameters](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Functions/rest_parameters) in staging, use the `--harmony-rest-parameters` command line flag
  - ES6: Implement the [spread operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator) in staging, use the `--harmony-spreadcalls` command line flag
  - Removed `SetIndexedPropertiesToExternalArrayData` and related APIs, forcing a shift to `Buffer` to be reimplemented based on `Uint8Array`
  - Introduction of `Maybe` and `MaybeLocal` C++ API for objects which _may_ or _may not_ have a value.
  - Added support for PPC

### Known issues

See https://github.com/nodejs/node/labels/confirmed-bug for complete and current list of known issues.

* Some problems with unreferenced timers running during `beforeExit` are still to be resolved. See [#1264](https://github.com/nodejs/node/issues/1264).
* Surrogate pair in REPL can freeze terminal. [#690](https://github.com/nodejs/node/issues/690)
* `process.send()` is not synchronous as the docs suggest, a regression introduced in 1.0.2, see [#760](https://github.com/nodejs/node/issues/760).
* Calling `dns.setServers()` while a DNS query is in progress can cause the process to crash on a failed assertion. [#894](https://github.com/nodejs/node/issues/894)
* `url.resolve` may transfer the auth portion of the url when resolving between two full hosts, see [#1435](https://github.com/nodejs/node/issues/1435).
