Hello Mongrel Users,

I’m writing a web server called Ebb. It’s written in C, makes use of  
the Mongrel HTTP parser, and uses libev its event loop. The goal is to  
be small, fast, and language independent server that can host web  
frameworks. I have written a small Ruby binding which provides a Rack  
handler - this will allow Ebb to host Rails, Merb, and other Ruby  
frameworks. In the future I will write a Python WSGI binding.

The design is similar to the evented Mongrel web server. Connections  
are processed as follows:

1. libev loops and waits for incoming connections.
2. When Ebb can read from a client socket, it passes the buffer into the  
mongrel state machine which parses the headers into name value pairs.
3. Ebb starts a new thread and passes the request information and peer  
socket  
to a user supplied callback. The thread lasts only for the length of  
that  
callback.
4. The included Ruby binding, supplying this callback transforms the  
request  
into a Rack compatible “env” variable and passes it on a Rack  
adapter.

The code measures in at less than 1000 lines of C code.

There is much work to do; it is not ready for use. I am soliciting  
help from the community for testing and development. You may browse  
the git repository at [Public Git Hosting - ebb.git/summary](http://repo.or.cz/w/ebb.git) or check out the  
code with this command:  
git clone git://repo.or.cz/ebb.git  
I release Ebb under the MIT license.  
It is very fun to program Ebb so I suggest you do too 🙂

A svn repo clone? (git-svn)? Not all jumped into the git bandwagon 🙂

Good luck with your new server! I also suggest looking at Thin which  
has been developed very recently and seems quite promising:

[http://code.macournoyer.com/thin/](http://code.macournoyer.com/thin/)

According to the benchmarks it’s the fastest Ruby web server currently.

Hey Ry,

Your project looks amazing. I had a look at rev to use libev, but it  
seems to be Ruby 1.9 only and I’m far from a C expert. So right now  
Thin uses EventMachine.

I really like your idea and I think we could help each other in  
building something very cool.  
If you’d like to participate in Thin and have some suggestions on how  
to make it better we should have a talk.  
Send me an email if you’re interested.

Marc

Sorry - my hosting abilities are limited. I also find the multitude of  
revision control software annoying (but git seems functional!)  
apt-get install git

no apt-get on Windows. And git support on it is a bit flacky  
(I hear another git versus \*nix versus windows discussion starting).

I’m on Bazaar, which is the same used by Ubuntu 🙂

[http://bazaar-vcs.org/BzrVsGit](http://bazaar-vcs.org/BzrVsGit)

Anyway, have git but not on my Windows box.

Will check your code this weekend 😉

Hey Ry-

Is glib-2.0 a dependency? It seems like 2.0 is an old version of  
glib. So ebb doesn’t compile on leopard out of the box. What do I need  
to install to make it work?

Hi Erza,

I’m not sure if glib is installed by default on macs. (Seems like it  
should be but I don’t see it on mine.) If you use fink you can do  
apt-get install glib2-dev  
The makefile is pretty hacky - make sure you have libev in your  
LIBRARY\_PATH and ev.h in your CPATH

An alternative might be [github.com](http://github.com). It looks like they provide svn  
mirrors of your git repos.

Ezra,

libev will be in MacPorts later tonight or tomorrow, and with glib2  
installed, Ebb builds cleanly on Leopard.

best,

Ry,

Awesome, great idea!

I will definitely be checking this out hopefully this weekend

Hey ry, did you tweaked the HttpParser like Thin guy did?

I was thinking about the modifications he did:

He removed all the if conditions evaluating http\_field,  
request\_method, request\_uri and others (most the ones that are  
allocated/initialized in HttpParser\_alloc).

But since I couldn’t find time to ask it in a separate mail, is time  
that boost the question using your thread 😉

svn mirror is coming, right? 😃

I don’t think those conditions were _removed_, I think they were  
_moved_, but I’ve only glanced at the C code and would barely know  
what I was looking at anyway. 🙂

No, he removed them:

[http://pastie.caboo.se/141633](http://pastie.caboo.se/141633)

The ragel code will generate the http11\_parser.c file, and http11.c  
file defines all the functions pointers:

http11.c:207…225:

VALUE HttpParser\_alloc(VALUE klass)  
{  
VALUE obj;  
http\_parser \*hp = ALLOC\_N(http\_parser, 1);  
TRACE();  
hp-\>http\_field = http\_field;  
hp-\>request\_method = request\_method;  
hp-\>request\_uri = request\_uri;  
hp-\>fragment = fragment;  
hp-\>request\_path = request\_path;  
hp-\>query\_string = query\_string;  
hp-\>http\_version = http\_version;  
hp-\>header\_done = header\_done;  
http\_parser\_init(hp);

obj = Data\_Wrap\_Struct(klass, NULL, HttpParser\_free, hp);

return obj;  
}

Theory indicates that allocation happens way before the ragel code is  
getting executed, so there is no need to evaluate the conditions all  
the time, ending with a speed boost.

Hey All,

Just one more quick message to entice contributors to take a look at  
Ebb. I was able to run some preliminary benchmarks for the first time  
today against evented Mongrel and Thin. They’re all running a small  
Camping application through Rack.

[![](http://s3.amazonaws.com/four.livejournal/20080121/ebb.png) ](http://s3.amazonaws.com/four.livejournal/20080121/ebb.png)

The code for that benchmark (and chart generation) can be found in the  
Ebb repo:  
[http://repo.or.cz/w/ebb.git?a=commit;h=c2fecde0a04603727949ec0b05d694be89a464d2](http://repo.or.cz/w/ebb.git?a=commit;h=c2fecde0a04603727949ec0b05d694be89a464d2)

yes I removed those conditions and looks like Ry did the same (by  
looking quickly at his code).

I didn’t know about those mods. I pulled the parser code from Thin.

Hi Luis,

I’ll put it on github when they open (or another service?) Apparently  
their svn bridge isn’t fully functional yet.

What you can do is ask for a rubyforge project and use the svn  
available there as mirror.

I’m still waiting to get bzr-git with write support so I can use  
bazaar all the way 🙂
