Simple comet pub/sub

cometpsd

Simple comet pub/sub server with an optional shared secret for controlling publish rights.

Open source licensed under MIT, by Rasmus Andersson.

Example

Start a server in a terminal:

$ cometpsd -k xyz

Open http://localhost:8080/channel/default in your web browser.

In another terminal, use curl to publish something:

$ curl -i -X POST -H 'X-CPS-Publish-Key: xyz' \
  --data-binary '<p>hello</p>' localhost:8080/channel/default

"hello" should appear in your browser when you run the command above. Open more tabs with http://localhost:8080/channel/default and run the curl command a few more times.

Configuration file

The server can be configured by a YAML file (passing filename, or "-" for stdin, with -f flag) which can describe multiple servers, which in turn each can describe multiple channels.

Parameters like address, port and log_level are hierarchical -- i.e. specifying log_level 3 for a server will implicitly set log_level 3 for all its channels which do not themselves set log_level.

Example

servers:
  - address: "0.0.0.0" # ANY
    port: 8080
    channels:
      test:
        publish_key: xyz
        log_level: 3
      test2:
        max_clients: 3

  - port: 8081
    log_level: 2
    channels: {a: {publish_key: xyz}, b: {}}

cometps's Issues

Error when running (Ubuntu 10.10 64bit)

With:
cometps$ cometpsd -k xyz
cometpsd: Command not found

Then i tried first to use make:
cometps$ make
cc -Wall -I/opt/local/include -I. -c cometpsd.c -o cometpsd.o
In file included from cometpsd.c:43:
yconf.h:4: fatal error: yaml.h: File not found

The last thing i tried was to create the missing yaml.h file:
servers:
address: "0.0.0.0" # ANY
port: 8080
channels:
test:
publish_key: xyz
log_level: 3
test2:
max_clients: 3

port: 8081
log_level: 2
channels: {a: {publish_key: xyz}, b: {}}

This result was a bunch of errors. Please advice what to do.

Thanks!
