A low-level Node.js binding for the Linux epoll API

epoll

A low-level Node.js binding for the Linux epoll API for monitoring multiple file descriptors to see if I/O is possible on any of them.

This module was initially written to detect EPOLLPRI events indicating that urgent data is available for reading. EPOLLPRI events are triggered by interrupt generating GPIO pins. The epoll module is used by onoff to detect such interrupts.

epoll supports Node.js versions 10, 12, 14, 16, 18 and 20.

Installation

Note that although it should be possible to install epoll on non-Linux systems the functionality offered by epoll is only available on Linux systems.

npm install epoll

API

• Epoll(callback) - Constructor. The callback is called when epoll events occur and it gets three arguments (err, fd, events).
• add(fd, events) - Register file descriptor fd for the event types specified by events.
• remove(fd) - Deregister file descriptor fd.
• modify(fd, events) - Change the event types associated with file descriptor fd to those specified by events.
• close() - Deregisters all file descriptors and free resources.

Event Types

• Epoll.EPOLLIN
• Epoll.EPOLLOUT
• Epoll.EPOLLRDHUP
• Epoll.EPOLLPRI
• Epoll.EPOLLERR
• Epoll.EPOLLHUP
• Epoll.EPOLLET
• Epoll.EPOLLONESHOT

Event types can be combined with | when calling add or modify. For example, Epoll.EPOLLPRI | Epoll.EPOLLONESHOT could be passed to add to detect a single GPIO interrupt.

Example - Watching Buttons

The following example shows how epoll can be used to detect interrupts from a momentary push-button connected to GPIO4 (pin P1-7) on the Raspberry Pi. The source code is available in the example directory and can easily be modified for using a different GPIO on the Pi or a different platform such as the BeagleBone.

The first step is to export GPIO4 as an interrupt generating input using the export bash script from the examples directory.

./export

export:

#!/bin/sh
echo 4 > /sys/class/gpio/export
sleep 1
echo in > /sys/class/gpio/gpio4/direction
echo both > /sys/class/gpio/gpio4/edge

Then run watch-button to be notified every time the button is pressed and released. If there is no hardware debounce circuit for the push-button, contact bounce issues are very likely to be visible on the console output. watch-button terminates automatically after 30 seconds.

node watch-button

watch-button:

const Epoll = require('epoll').Epoll;
const fs = require('fs');

const valuefd = fs.openSync('/sys/class/gpio/gpio4/value', 'r');
const buffer = Buffer.alloc(1);

// Create a new Epoll. The callback is the interrupt handler.
const poller = new Epoll((err, fd, events) => {
  // Read GPIO value file. Reading also clears the interrupt.
  fs.readSync(fd, buffer, 0, 1, 0);
  console.log(buffer.toString() === '1' ? 'pressed' : 'released');
});

// Read the GPIO value file before watching to
// prevent an initial unauthentic interrupt.
fs.readSync(valuefd, buffer, 0, 1, 0);

// Start watching for interrupts.
poller.add(valuefd, Epoll.EPOLLPRI);

// Stop watching after 30 seconds.
setTimeout(_ => {
  poller.remove(valuefd).close();
}, 30000);

When watch-button has terminated, GPIO4 can be unexported using the unexport bash script.

./unexport

unexport:

#!/bin/sh
echo 4 > /sys/class/gpio/unexport

Example - Interrupts Per Second

The following example shows how epoll can be used to determine the number of hardware interrupts that can be handled per second on the Raspberry Pi. The source code is available in the example directory and can easily be modified to use different GPIOs on the Raspberry Pi or a different platform such as the BeagleBone.

In this example, GPIO7 is wired to one end of a 1kΩ current limiting resistor and GPIO8 is wired to the other end of the resistor. GPIO7 is an input and GPIO8 is an output.

The first step is to export GPIOs #7 and #8 using the export bash script from the examples directory.

./export

export:

#!/bin/sh
echo 7 > /sys/class/gpio/export
echo 8 > /sys/class/gpio/export
sleep 1
echo in > /sys/class/gpio/gpio7/direction
echo both > /sys/class/gpio/gpio7/edge
echo out > /sys/class/gpio/gpio8/direction

Then run interrupts-per-second. interrupts-per-second toggles the state of the output every time it detects an interrupt on the input. Each toggle will trigger the next interrupt. After five seconds, interrupts-per-second prints the number of interrupts it detected per second.

node interrupts-per-second

interrupts-per-second:

const Epoll = require('../../').Epoll;
const fs = require('fs');

const value = Buffer.alloc(1); // The three Buffers here are global
const zero = Buffer.from('0'); // to improve performance.
const one = Buffer.from('1');

const inputfd = fs.openSync('/sys/class/gpio/gpio7/value', 'r+');
const outputfd = fs.openSync('/sys/class/gpio/gpio8/value', 'r+');

let count = 0;

// Create a new Epoll. The callback is the interrupt handler.
const poller = new Epoll((err, fd, events) => {
  count += 1;

  // Read GPIO value file. Reading also clears the interrupt.
  fs.readSync(inputfd, value, 0, 1, 0);

  // Toggle GPIO value. This will eventually result
  // in the next interrupt being triggered.
  const nextValue = value[0] === zero[0] ? one : zero;
  fs.writeSync(outputfd, nextValue, 0, nextValue.length, 0);
});

let time = process.hrtime(); // Get start time.

// Start watching for interrupts. This will trigger the first interrupt
// as the value file already has data waiting for a read.
poller.add(inputfd, Epoll.EPOLLPRI);

// Print interrupt rate to console after 5 seconds.
setTimeout(_ => {
  time = process.hrtime(time); // Get run time.
  const rate = Math.floor(count / (time[0] + time[1] / 1E9));
  console.log(rate + ' interrupts per second');

  // Stop watching.
  poller.remove(inputfd).close();
}, 5000);

When interrupts-per-second has terminated, GPIOs #7 and #8 can be unexported using the unexport bash script.

./unexport

unexport:

#!/bin/sh
echo 7 > /sys/class/gpio/unexport
echo 8 > /sys/class/gpio/unexport

Here are some results from the "Interrupts Per Second" example.

epoll's Issues

Inaccurate interrupt detection after sometime of being idle

Hi, I'm trying to interface a multi coin acceptor with Espressobin. This coin acceptor emits pulses for every coin inserted. For example 1 peso coin (I'm in philippines) pulses 0 for 20ms and then pulses 1 for 100ms (using 'both' edge). It turns the GPIO input to 0 for 20ms and turns to 1 for 100ms. It does this one time for 1 peso coin and 5 times for 5 peso coin.

So if you print the value of 'both' edge every time an interrupt occurs, this is the output:

1 peso coin:

0
1 (after 20ms)

5 peso coin:

0
1 (after 20ms)
0 (after 100ms)
1 (after 20ms)
0 (after 100ms)
1 (after 20ms)
0 (after 100ms)
1 (after 20ms)

The problem is that sometimes, some of the interrupts are not detected by the epoll library when I'm no longer interacting with the coin acceptor after sometime. What happens is, for example inserting a 5 peso coin to the multi coin acceptor results to:

1 (after 20ms) - it skipped the first `falling edge` and/or
1 or 0 (after 120ms) - it skipped the falling/rising edge detection
0 (after 100ms)
1 (aftter 20ms)
0 (after 100ms)
1 (after 20ms)
0 (after 100ms)
1 (after 20ms)

I think the interrupt detection job is somewhat put to background or something that's why it can't properly detect the pulses when there is no activity for some time. In the next consecutive insertion of coins, it properly detects the coins again.

I can confirm that the problem is not the circuit or the coin acceptor because this doesn't happen when I use the same schematics on raspberry pi's GPIO and a python script.

I'd just like to know if you have any idea on top of your head what might be the cause of this issue.

epoll.node bindings file unable to locate

following error coming. I think its issue with the epoll module. I'm using it to write on lcd using lcd module on BBB. Any help will be appreciated.

Add node-gyp to package dependencies

Can we add node-gyp to the package dependencies? Currently it's expected to be installed, but not listed as one of the things this package needs. This means Yarn PNP can't install a project that depends on this, and the user has to already have node-gyp in the path.

Replace NanSymbol with NanNew<v8:String>

NanSymbol will be deprecated soon so replace it with NanNewv8:String

nan no longer works due to ABI interface changes in node and electron

see nodejs/nan#922 (comment)

using electron-rebuild with electron v20
export DEBUG=electron-rebuild

epoll rebuilds fine with just node v16.16.0

Add prebuilt binaries?

It would be nice if the epoll library had some prebuilt binaries shipping with it, either using the low-level node-pre-gyp or the higher-level prebuild and prebuild-install libraries. If epoll came pre-built for the Raspberry Pi architecture, users wouldn't have to install Python, make, or g++ to install the package anymore, which would make it a lot faster for new users to use.

Error: Module version mismatch. Expected 50, got 48.module (Electron)

I've want to use rpi-gpio within electron and got the following error, I figured out that it's an issue of epoll. Would be very thankful for any help!

Removing fd from epoll does not work

Hi,

I got a 3300Hz pulse attached to a RPI2 GPIO pin. And if I test the interrupts with this script

// echo 17 > /sys/class/gpio/export
// echo in > /sys/class/gpio/gpio17/direction
// echo rising > /sys/class/gpio/gpio17/edge

var Epoll = require('epoll').Epoll,
  fs = require('fs'),
  inputfd = fs.openSync('/sys/class/gpio/gpio17/value', 'r+'),
  value = new Buffer(1),  // The three Buffers here are global
  count = 0,
  time;

// Create a new Epoll. The callback is the interrupt handler.
var poller = new Epoll(function (err, fd, events) {
  count++;
  // Read GPIO value file. Reading also clears the interrupt.
  fs.readSync(inputfd, value, 0, 1, 0);
});

time = process.hrtime(); // Get start time.

// Start watching for interrupts. This will trigger the first interrupt
// as the value file already has data waiting for a read.
poller.add(inputfd, Epoll.EPOLLPRI);

// Print interrupt rate to console after 5 seconds.
setTimeout(function () {
  var rate;

  time = process.hrtime(time); // Get run time.
  rate = Math.floor(count / (time[0] + time[1] / 1E9));
  console.log(rate + ' interrupts per second');

  // Stop watching.
  poller.remove(inputfd).close();
}, 5000);

the kworker process still is at ~8% cpu usage after the script has finished. If I disconnect the source from the pin the cpu usage goes down to 0%, so I think the deregistration of the fd does not work properly.

// Edit:
Linux raspberrypi 4.1.17-v7+ #838 SMP Tue Feb 9 13:15:09 GMT 2016 armv7l GNU/Linux

Installing dummy module for Windows

Hi --

I know this project makes no sense in running on Windows, but I do all of my development on a Windows machine before doing testing on my Raspberry Pi. As such, in my code I've abstracted away the actual calls to rpi-gpio (which uses epoll) such that I never actually invoke any code which hits epoll.

However, Node still complains that the module did not self-register even though the methods will not be called.

A quick work-around I had was to modify epoll.cc and epoll.h slightly to provide an implementation for Windows platform which does nothing. Only registers the module and provides no implementation for the API. I assume I could just no-op all of the methods so it won't blow up when trying to call them, will test this out.

My question is, would such a contribution be useful for this project? Or should I keep this in my own fork (and subsequent forked npm package)?

Thanks for the useful project!

epoll 64bit support for Raspberry Pi 4B error epoll.node: wrong ELF class: ELFCLASS64

After giving up on fighting with getting my program running on my Banana Pi M64 I learned that Raspberry Pi had released a V4 with better performance specs, cheaper price than the BPi and more readily available via Amazon Prime. It's been much smoother sailing until I ran into this error.

Does epoll not support 64 bit system architecture? Is there a work-around I can try?

Add a closed property to Epoll

closed will return true if close was already called, else false.

libuv compatibility

Recent versions of libuv functions return -errno on error, older versions don't. For example, here's how uv_sem_init is implemented in libuv v0.11.1 and v0.11.14 respectively:

int uv_sem_init(uv_sem_t* sem, unsigned int value) {
  return sem_init(sem, 0, value);
}

int uv_sem_init(uv_sem_t* sem, unsigned int value) {
  if (sem_init(sem, 0, value))
    return -errno;
  return 0;
}

Take this into account.

0.11.9+ compatibility

Node v0.11.9 comes with a breaking v8 change. See NAN News & Updates for more information. Update epoll when NAN v0.6.0 is released.

Epoll.EPOLLET.toString(16) returns -80000000

Currently Epoll.EPOLLET is -0x80000000 but it should be 0x80000000. This results in the calls to args[1]->IsUint32() in the Add and Modify methods rejecting Epoll.EPOLLET as an invalid argument.

In some scenarios there can be segmentation faults. This is probably because Ref/Unref is not being used for Epoll instances.

Error: The module epoll.node was compiled against a different Node.js version using NODE_MODULE_VERSION 93

Hi, I'm getting incompatibility errors when using onoff (which has dependency on this project's latest version). Would you be able to recompile against the newest Node LTS version which is 16.13.0 at the moment?

Full error:

Error: The module /local/path/epoll.node was compiled against a different Node.js version using NODE_MODULE_VERSION 93. This version of Node.js requires NODE_MODULE_VERSION 85.

rebuilding with npm rebuild epoll --update-binary does not help

Thanks in advance!

Refactor interrupts per second example

The Linux 3.13 kernel dropped support for detecting changes on GPIO output pins per hardware interrupt.

The interrupts per second example currently relies on this feature and needs to be refactored to use an alternative technique.

Drop support for Node.js v0.10, v0.12, v5 and v7

epoll interrupt handling any more robust now?

A couple years ago I tried using epoll via this package for interrupt handling and I had a heck of time with none or excessive tripping. I tried all manner of debouncing to no avail. I gave up and started using pigpio which was way more stable and many times did not require any debouncing (for interrupt by physical switch). That code has now been battle tested for two years (I have 64 physical switches connected on 4 mcp23017 chips throwing interrupts via 8 pins on gpio bus).

That's all good but of course pigio library requires pi hardware and the pigioc library. That leaves out all my new groovy sbcs :-(.

Now two years later do you feel using your epoll package (via onoff) for interrupts is any more robust and stable on par with pigio? Were there interrupt issues that you specifically addressed in the last two years?

If so maybe I'll give onoff another shot.
I suppose I'll have to try implementing this anyway as I (and many others) are moving from pi hardware and thus the pigio library.

---

Do you know of any non epoll ways to monitor linux interrupts on say a rockchip64? I guess this is all a can of worms every sbc having different hardware architecture even if they share the same processor. Seems like a manufacturer should supply a devicetree module for their gpio bus interrupt with some standard software interface API.

Electron - Requiring Native Modules in the Renderer Process to be NAPI or Context Aware

As mentioned in the following issue for electron, support for native modules that are not NAPI or Context Aware are going to be dropped. Electron Issue

This will result in applications that use epoll/onoff being broken after Electron 12.

Applications based on electron 10+ require the flag app.allowRendererProcessReuse = false in the Electron main.js.

AsyncResource constructed at the incorrect time

The AsyncResource required for a callback should be constructed when the callback is stored for later invocation. This allows the async context to be restored at the callback invocation time. Currently the AsyncResource is constructed at callback invocation time and doesn't restore the correct async context.

To give some context, I use it in the following project: https://github.com/gingters/bsc-ampel
I did a fresh npm install and that fails with the aforementioned problem.
I then have to rebuild that for electron, to use that in the app, but already the first installation and compilation for node fails.

That worked two or three weeks ago (with an older version, I think 2.0.3), and now I don't know how to solve that. Please advise.

Failure to install epoll

I'm trying to install onoff on a Raspberry Pi 3 and it's failing due to an epoll error, apparently. The OS is DietPi, which is based on Debian 11 bullseye. It's a freshly-installed system, the Node version is v16.14.2 and npm is v8.7.0.

Issue #44 seems similar, but this doesn't seem to be a Python issue. In the debug logs below you can see it finds Python 3.9.2. Any idea what's wrong here? Thanks a lot in advance!

$ npm install onoff --verbose

nan 1.0.0 alignment

A number of things need to be adjusted when nan 1.0.0 is released.

---

NanAssignPersistent has two parameters rather than three, the first is no longer required, so

NanAssignPersistent(v8::FunctionTemplate, constructor, ctor);

becomes

NanAssignPersistent(constructor, ctor);

---

There's now a NanNew function template and template specializations for creating new v8 objects. See also NanUndefined, NanNull, NanTrue, and NanFalse. They hide the isolate dependencies. For example

v8::FunctionTemplate::New(Epoll::New)

becomes

NanNew<v8::FunctionTemplate>(Epoll::New)

---

NanNewLocal has been removed and NanNew should be used as a replacement, so if NanNull is also used

NanNewLocal<v8::Value>(v8::Null())

becomes

NanNew(NanNull())

---

Are any other alignments required?

Epoll module does not install on latest debian image for BeagleBone

Refactor the thread code...

... it looks terrible.

EINTR handling

If epoll_wait returns -1 and errno is EINTR don't handle it as an error.

Module did not self-register

Trying to use the onoff library inside my project but I always get a "Module did not self-register" error from the epoll module (bindings.js line 83).

Using latest nodejs version (tried with several other older versions back to 0.10.x). Trying inside VisualStudio, Win8.1 64bit.
Same error happens also if I try to require only the 'epoll' module.

Any idea what's causing this?

Thanks

Documentation Request: Can't install on Non-Linux systems

Once I found the information that you can't install this module on non-Linux systems (#12 (comment)) it totally made sense—but I spent about 45 minutes trying to figure out what was going on before I was able to find that thread. The errors one gets suggest problems with node-gyp or bindings, which are both red herrings.

Would it be possible to add something to the README just calling this out, to save future people a little heartache and time?

node-gyp installation fails on raspbian

Hi,

I am having struggle with epoll installation on raspberry pi 2 (model B).

Versions:

• Raspbian GNU/Linux 11 (bullseye)
• NodeJs 16.13.0
• NPM 8.1.0
• Python 3.9.2

I can see from the log that it has an issue with getting python version (it's syntax). When I try to do the same command directly in python shell, the error is the same.

Any hints how to get around this? Do I need to downgrade Python? (I have the latest one at this moment)

Thanks,
Martin
