A pure stream http push technology for your Nginx setup.
Comet made easy and really scalable.
This module is not distributed with the Nginx source. See the installation instructions.
Available on github at nginx_push_stream_module
Always take a look at CHANGELOG.textile to see what’s new.
After you try this module and like it, feel free to give something back, and help in the maintenance of the project ;)
This module is considered production ready.
You may use build.sh
script inside the project:
# clone the project git clone http://github.com/wandenberg/nginx-push-stream-module.git NGINX_PUSH_STREAM_MODULE_PATH=$PWD/nginx-push-stream-module cd nginx-push-stream-module # build with 1.0.x, 0.9.x, 0.8.x series ./build.sh master 1.0.5 cd build/nginx-1.0.5 # install and finish sudo make install # check sudo /usr/local/nginx/sbin/nginx -v nginx version: nginx/1.0.5 # test configuration sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf -t the configuration file $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf syntax is ok configuration file $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf test is successful # run sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf
Or you may do by yourself:
# clone the project git clone http://github.com/wandenberg/nginx-push-stream-module.git NGINX_PUSH_STREAM_MODULE_PATH=$PWD/nginx-push-stream-module # get desired nginx version (works with 1.0.x, 0.9.x, 0.8.x series) wget http://nginx.org/download/nginx-1.0.5.tar.gz # unpack, configure and build tar xzvf nginx-1.0.5.tar.gz cd nginx-1.0.5 ./configure --add-module=../nginx-push-stream-module make # install and finish sudo make install # check sudo /usr/local/nginx/sbin/nginx -v nginx version: nginx/1.0.5 # test configuration sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf -t the configuration file $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf syntax is ok configuration file $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf test is successful # run sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf
Just as information is listed below the minimum amount of memory used for each object:
- message on shared = 200 bytes
- channel on shared = 536 bytes
- subscriber
- on shared = 230 bytes
- on system = 6500 bytes
location /channels-stats { # activate channels statistics mode for this location push_stream_channels_statistics; # query string based channel id set $push_stream_channel_id $arg_id; } location /pub { # activate publisher (admin) mode for this location push_stream_publisher admin; # query string based channel id set $push_stream_channel_id $arg_id; } location ~ /sub/(.*) { # activate subscriber (streaming) mode for this location push_stream_subscriber; # positional channel path set $push_stream_channels_path $1; }
You can feel the flavor right now at the command line. Try using more than
one terminal and start playing http pubsub:
# Pubs curl -s -v -X POST 'http://localhost/pub?id=my_channel_1' -d 'Hello World!' curl -s -v -X POST 'http://localhost/pub?id=your_channel_1' -d 'Hi everybody!' curl -s -v -X POST 'http://localhost/pub?id=your_channel_2' -d 'Goodbye!' # Subs curl -s -v 'http://localhost/sub/my_channel_1.b20' curl -s -v 'http://localhost/sub/your_channel_1.b20' curl -s -v 'http://localhost/sub/your_channel_2.b20' # Channels Stats for publisher (json format) curl -s -v 'http://localhost/pub?id=my_channel_1' # All Channels Stats summarized (json format) curl -s -v 'http://localhost/channels-stats' # All Channels Stats detailed (json format) curl -s -v 'http://localhost/channels-stats?id=ALL' # Prefixed Channels Stats detailed (json format) curl -s -v 'http://localhost/channels-stats?id=your_channel_*' # Channels Stats (json format) curl -s -v 'http://localhost/channels-stats?id=my_channel_1' # Delete Channels curl -s -v -X DELETE 'http://localhost/pub?id=my_channel_1'
Using an invisible iFrame on the page to receive the messages and pass them to main page.
This example uses the PushStream class present in misc/js/pushstream.js file, copy it to your server htdocs.
Configure your server like suggested bellow. You should complete this configuration with other directives according with target application.
Create a html page with the content on Client part, access it from browser and try with the command curl http://localhost/pub?id=ch1 -d “Some Text”.
Server:
location /pub { # activate publisher (admin) mode for this location push_stream_publisher admin; # query string based channel id set $push_stream_channel_id $arg_id; } location ~ /sub/(.*) { # activate subscriber (streaming) mode for this location push_stream_subscriber; # positional channel path set $push_stream_channels_path $1; # header to be sent when receiving new subscriber connection push_stream_header_template "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">\r\n<meta http-equiv=\"Cache-Control\" content=\"no-store\">\r\n<meta http-equiv=\"Cache-Control\" content=\"no-cache\">\r\n<meta http-equiv=\"Pragma\" content=\"no-cache\">\r\n<meta http-equiv=\"Expires\" content=\"Thu, 1 Jan 1970 00:00:00 GMT\">\r\n<script type=\"text/javascript\">\r\nwindow.onError = null;\r\ndocument.domain = 'localhost';\r\nparent.PushStream.register(this);\r\n</script>\r\n</head>\r\n<body onload=\"try { parent.PushStream.reset(this) } catch (e) {}\">"; # message template push_stream_message_template "<script>p(~id~,'~channel~','~text~');</script>"; # footer to be sent when finishing subscriber connection push_stream_footer_template "</body></html>"; # content-type push_stream_content_type "text/html; charset=utf-8"; # ping frequency push_stream_ping_message_interval 10s; }

Using EventSource to receive the messages.
This example uses the PushStream class present in misc/js/pushstream.js file, copy it to your server htdocs.
Configure your server like suggested bellow. You should complete this configuration with other directives according with target application.
Create a html page with the content on Client part, access it from browser and try with the command curl http://localhost/pub?id=ch1 -d “Some Text”.
Server:
location /pub { # activate publisher (admin) mode for this location push_stream_publisher admin; # query string based channel id set $push_stream_channel_id $arg_id; } location ~ /ev/(.*) { # activate subscriber mode for this location push_stream_subscriber; # activate event source support for this location push_stream_eventsource_support on; # positional channel path set $push_stream_channels_path $1; # message template push_stream_message_template "{\"id\":~id~,\"channel\":\"~channel~\",\"text\":\"~text~\"}"; # ping frequency push_stream_ping_message_interval 10s; }
Client:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <title>Event Source Example</title> </head> <body> <p>Messages:</p> <div id="messages" style="width:800px;height:300px;overflow:scroll;"></div> <script src="/js/pushstream.js" type="text/javascript" language="javascript" charset="utf-8"></script> <script type="text/javascript" language="javascript" charset="utf-8"> // <![CDATA[ function messageReceived(text, id, channel) { document.getElementById('messages').innerHTML += id + ': ' + text + '<br>'; }; var pushstream = new PushStream({ host: window.location.hostname, port: window.location.port, modes: "eventsource" }); pushstream.onmessage = messageReceived; pushstream.addChannel('ch1'); pushstream.connect(); // ]]> </script> </body> </html>
Observations:
- push_stream_message_template should be exactly like as the example to be used with PushStream class
- EventSource and Forever iFrame may be combined setting /sub and /ev locations on same server and setting modes: “eventsource|stream” on client. With that if the browser supports Event Source, it will use it, if not it will use iFrame.
Using WebSocket to receive the messages.
This example uses the PushStream class present in misc/js/pushstream.js file, copy it to your server htdocs.
Configure your server like suggested bellow. You should complete this configuration with other directives according with target application.
Create a html page with the content on Client part, access it from browser and try with the command curl http://localhost/pub?id=ch1 -d “Some Text”.
Server:
location /pub { # activate publisher (admin) mode for this location push_stream_publisher admin; # query string based channel id set $push_stream_channel_id $arg_id; } location ~ /ws/(.*) { # activate websocket mode for this location push_stream_websocket; # positional channel path set $push_stream_channels_path $1; # message template push_stream_message_template "{\"id\":~id~,\"channel\":\"~channel~\",\"text\":\"~text~\"}"; # store messages in memory push_stream_store_messages on; push_stream_websocket_allow_publish on; # ping frequency push_stream_ping_message_interval 10s; }

Observations:
- push_stream_message_template should be exactly like as the example to be used with PushStream class
- WebSocket, EventSource and Forever iFrame may be combined setting /ws, /sub and /ev locations on same server and setting modes: “websocket|eventsource|stream” on client. With that if the browser supports Websocket or Event Source, it will use it, if not it will use iFrame, following the order on modes attribute.
Using jQuery to receive the messages.
This example uses jQuery file, put it on your server htdocs.
Configure your server like suggested bellow. You should complete this configuration with other directives according with target application.
Create a html page with the content on Client part, access it from browser and try with the command curl http://localhost/pub?id=ch1 -d “Some Text”.
Server:
location /pub { # activate publisher (admin) mode for this location push_stream_publisher admin; # query string based channel id set $push_stream_channel_id $arg_id; } location ~ /lp/(.*) { # activate long-polling mode for this location push_stream_subscriber long-polling; # positional channel path set $push_stream_channels_path $1; # message template push_stream_message_template "{\"id\":~id~,\"channel\":\"~channel~\",\"text\":\"~text~\"}"; # connection timeout push_stream_longpolling_connection_ttl 30s; }

Observations:
- push_stream_message_template should be exactly like as the example to be used with PushStream class
values: channel id
location: push_stream_publisher, push_stream_channels_statistics
A string to uniquely identify a communication channel. Must be present on location of the push_stream_publisher and push_stream_channels_statistics.
set $push_channel_id $arg_id; #channel id is now the url query string parameter "id" #(/pub?id=channel_id_string or /channels-stats?id=channel_id_string)
values: set of channels id and backtrack desired messages
location: push_stream_subscriber
A string representing a set of channels id and backtrack desired messages separated by slash, example /channel1.b3/channel2.b5/channel3.b2.
The backtrack means the amount of old messages from each of the channels that will be delivered to the subscriber. On the example will be 3 messages from channel1, 5 from channel2 and 2 from channel3.
Backtrack isn’t needed, you can only sign channels without get old messages, or you can mix things.
More accepted examples: /channel1 , /channel1/channel2 , /channel1.b5/channel2 , /channel1/channel2.b6 , …
Must be present on location of the push_stream_subscriber.
location /sub/(.*) { set $push_stream_channels_path $1; } #channels path is now part of url #(/sub/channel_id_string or /sub/channel_id_string.b2/other_channel)
syntax: push_stream_channels_statistics
context: location
release version: 0.2.0
Defines a location as a source of statistics. You can use this location to get statistics about a specific, group or all channels, in a resumed ou summarized way.
To get statistics about all channels in a summarized way you have to make a GET in this location without specify a name in the push_stream_channel_id variable.
To get statistics about all channels in a detailed way you have to specify “ALL” in the push_stream_channel_id.
To get statistics about prefixed channels in a detailed way you have to specify “_prefix_*” in the push_stream_channel_id.
To get statistics about a channel you have to specify the name in the push_stream_channel_id.
You can get statistics in the formats plain, xml, yaml and json. The default is json, to change this behavior you can use Accept header parameter passing values like “text/plain”, “application/xml”, “application/yaml” and “application/json” respectivelly.
location /channels-stats { push_stream_channels_statistics; set $push_stream_channel_id $arg_id; } # /channels-stats -> get statistics about all channels in a summarized way # /channels-stats?id=ALL -> get statistics about all channels in a detailed way # /channels-stats?id=channel_* -> get statistics about all channels which starts with 'channel_' # /channels-stats?id=channel_id -> get statistics about a channel
syntax: push_stream_publisher [normal | admin]
default: normal
context: location
Defines a location as a message publisher. Requests to a publisher location are treated as messages to be sent to subscribers.
This location supports three http methods:
GET, make possible to get statistics about the channel
POST, publish a message to the channel
DELETE, remove any existent stored messages, disconnect any subscriber, and delete the channel. Available only if admin value is used in this directive.
# normal publisher location location /pub { push_stream_publisher; set $push_stream_channel_id $arg_id; } # GET /pub?id=channel_id -> get statistics about a channel # POST /pub?id=channel_id -> publish a message to the channel # admin publisher location location /pub_admin { push_stream_publisher admin; set $push_stream_channel_id $arg_id; } # GET /pub_admin?id=channel_id -> get statistics about a channel # POST /pub_admin?id=channel_id -> publish a message to the channel # DELETE /pub_admin?id=channel_id -> delete the channel
syntax: push_stream_subscriber [streaming | polling | long-polling]
default: streaming
context: location
Defines a location as a subscriber. This location represents a subscriber’s interface to a channel’s message queue.
This location only supports GET http method to receive published messages.
And has three possible values to set push mode: streaming, polling, long-polling. The default values is streaming.
The polling and long-polling modes could be set by the request header X-Nginx-PushStream-Mode overriding push_stream_subscriber directive value.
# streaming subscriber location location /sub/(.*) { push_stream_subscriber; # positional channel path set $push_stream_channels_path $1; } curl localhost/sub/ch1 -H 'X-Nginx-PushStream-Mode:polling' #polling request on a streaming location curl localhost/sub/ch1 -H 'X-Nginx-PushStream-Mode:long-polling' #long-polling request on a streaming location # polling subscriber location location /sub/(.*) { push_stream_subscriber polling; # positional channel path set $push_stream_channels_path $1; } curl localhost/sub/ch1 #polling request curl localhost/sub/ch1 -H 'X-Nginx-PushStream-Mode:long-polling' #long-polling request on a polling location # long polling subscriber location location /sub/(.*) { push_stream_subscriber long-polling; # positional channel path set $push_stream_channels_path $1; } curl localhost/sub/ch1 #long-polling request curl localhost/sub/ch1 -H 'X-Nginx-PushStream-Mode:polling' #polling request on a logn-polling location
syntax: push_stream_websocket
default: none
context: location
release version: 0.3.2
Defines a location as a subscriber using WebSocket protocol. This location represents a subscriber’s interface to a channel’s message queue.
This location only supports GET http method to receive published messages.
# websocket subscriber location location /ws/(.*) { push_stream_websocket; # positional channel path set $push_stream_channels_path $1; }
syntax: push_stream_shared_memory_size size
default: 32M
context: http
The size of the memory chunk this module will use to store published messages, channels and other shared structures.
When this memory is full any new request for publish a message or subscribe a channel will receive an 500 Internal Server Error response.
syntax: push_stream_shared_memory_cleanup_objects_ttl time
default: 30 seconds
context: http
The length of time a message or a channel will stay on garbage collection area before it is completly discarded, freeing the shared memory. The minimum length is 30 seconds to ensure that no one is using these elements.
This operation is very important to help Nginx recycle memory consumed to create messages and channels, so do not use a large time.
syntax: push_stream_channel_deleted_message_text string
default: Channel deleted
context: http
release version: 0.2.5
The string used on channel deleted message sent to subscribers when the channel is deleted by a publisher.

syntax: push_stream_max_channel_id_length number
default: none
context: http
Maximum permissible channel id length (number of characters). Longer ids will receive an 400 Bad Request response. If you do not want to limit channel id length, just not set this directive.
syntax: push_stream_max_number_of_channels number

syntax: push_stream_broadcast_channel_prefix string
default: none
context: http
The string prefix used to identify when a channel is a normal or broadcast channel, example: when you set this directive as “bd_”, “bd_ch1” will be a broadcast channel
syntax: push_stream_store_messages on | off
default: off
context: location (push_stream_publisher)
Whether or not message queuing is enabled.
If store messages is “on” is needed to set at least one of these two directives push_stream_message_ttl or push_stream_max_messages_stored_per_channel.
syntax: push_stream_authorized_channels_only on | off
default: off
context: location (push_stream_subscriber)
Whether or not a subscriber may create a channel by making a request to a push_stream_subscriber location. If set to on, a publisher must send a POST request before a subscriber can request messages on the channel. Otherwise, all subscriber requests to nonexistent channels will get a 403 Forbidden response.
This restriction is not applied to broadcast channels, but to subscribe to a broadcast channel is necessary to subscribe at least to one normal channel, and if this directive is set to on this channel has to be created before.
syntax: push_stream_header_template string
default: none
context: location (push_stream_subscriber)
The text that will be sended to subscribers when they arrive.
syntax: push_stream_message_template string
default: ~text~
context: location (push_stream_subscriber)
The text template that will be used to format the message before be sended to subscribers. The template can contain any number of the reserved words: ~id~, ~text~, ~channel~, ~time~, ~tag~ and ~event-id~, example: "<script>p(~id~,'~channel~','~text~', ~tag~, '~time~');</script>"

syntax: push_stream_broadcast_channel_max_qtd number
default: none
context: location (push_stream_subscriber)
The maximum number of broadcast channels that a subscriber may sign on the request.
This directive works in conjunction with push_stream_authorized_channels_only to preserve the server from a kind of attack where a subscriber sign one normal channel and many nonexistent broadcast channels.
syntax: push_stream_keepalive on | off
default: off
context: location (push_stream_publisher, push_stream_channels_statistics)
release version: 0.2.4
Enable keepalive connections, on publisher or channels statistics locations.

default: none
context: location (push_stream_subscriber)
The length of time a subscriber will stay connected before it is considered expired and disconnected. If you do not want subscribers to be automatically disconnected, just not set this directive.
But, this operation is very important to help Nginx recycle memory consumed to send messages to susbscriber, allocated at pool request.

default: value in push_stream_subscriber_connection_ttl
context: location (push_stream_subscriber)
release version: 0.3.1

But, this operation is very important to help Nginx recycle memory consumed to send messages to susbscriber, allocated at pool request.
syntax: push_stream_websocket_allow_publish on | off
default: off
context: location
release version: 0.3.2
Enable a WebSocket subscriber send messages to the channel it is connected (the first, if connected in more than one) through the same connection it is receiving the messages, using send method from WebSocket interface.
syntax: push_stream_last_received_message_time string
default: none
context: location
release version: 0.3.3
Set the time when last message was received to the server knows which messages has to be sent to subscriber. Is a replacement for If-Modified-Since header. Example, $arg_time indicate that the value will be take from time argument.
syntax: push_stream_last_received_message_tag string
default: none
context: location
release version: 0.3.3
Set the tag of the last message received to the server knows which messages has to be sent to subscriber. Is a replacement for If-None-Match header. Example, $arg_tag indicate that the value will be take from tag argument.
This module controls everything needed to send the messages to subscribers.
So it disable Nginx’s chuncked filter to reduce memory consumption in streaming connections.
The tests for this module are written in Ruby, and are acceptance tests.
To run them is needed to have an environment with:
- Basic requirements
- ruby >= 1.8.7
- rubygems >= 1.6.2
- rake >= 0.8.7
- Required gems
- POpen4 >= 0.1.4
- em-http-request >= 0.2.14
- json >= 1.4.3
- ruby-debug >= 0.10.4
- jasmine >= 1.0.2.1
- nokogiri >= 1.5.0
- jshint >= 0.1.1
You can install these gems with bundler (bundler is required to be installed before, gem install bundler)
cd test/ bundle install --without docs
or individually
gem install POpen4 -v 0.1.4 gem install em-http-request -v 0.2.14 gem install json -v 1.4.3 gem install ruby-debug -v 0.10.4 gem install jasmine -v 1.0.2.1 gem install nokogiri -v 1.5.0 gem install jshint -v 0.1.1
Then issue rake tests
.
This command run the tests using nginx executable located at /usr/local/nginx/sbin/nginx with 1 worker responding at host localhost and port 9990.
To change this behavior use the commands bellow
rake tests executable="../build/nginx-1.0.5/objs/nginx" # to change default path for nginx executable rake tests host=my_machine # to change default hostname rake tests port=9889 # to change default port rake tests workers=2 # to change dafault number of workers used and can combine any of these parameters, like: rake tests port=9889 executable="../build/nginx-1.0.5/objs/nginx"
