You are certainly right for someone who has done this before, but to us
newbies it seems scary to think of installing, configuring, and managing
Apache.

And if the Seaside app we build is, in turn, not delivered as an
extranet-based web service but instead installed separately by individual
end-users or small groups, it is even more of an issue there.

So while I understand the cons, I definitely see some pros as well.

Well, for internal deployments of this small scale that don't need ssl and other advanced features Swazoo, Kom and others are already good enough, isn't it?

Dunno. e.g. Does Swazoo server static content? I don't think Kom does. Not
sure what other "features" make or don't make sense, and I do understand the
points about not re-inventing Apache.

Unsure ... Sophie

Swazoo is fine (I think). Kom is missing a way to bind only to 127.0.0.1 if
it is indeed only for a personal installation. I was going to help fix Kom to
bind to specific IPs, but now that I know Swazoo does it, I'm abandoning Kom,
sorry.

Re: [Seaside] Re: Re: Swazoo as reverse proxy?

Both serve content from libraries well enough, did you mean some other static content? Dumping those resources to the front end web server is usually done only for larger deployments as an optimization...

WAFileLIbrary? I meant static file-system content. I see that as a feature,
not an optimization.

Seaside will be able to do that in 2.9.

This is a one line change to Kom. Look at #pvtNewListener: . The
send to #listenOn:backlogSize: can be changed to
#listenOn:backlogSize:interface: . For example:

pvtNewListener: backlogSize
"Create a new socket that listens on our port. The backlog is how
many simultaneous
connections to accept at the same time"

| listener |
listener := self socketClass newTCP.
self socketsToDestroy add: listener.
listener listenOn: portNumber backlogSize: backlogSize interface:
#(127 0 0 1) asByteArray.
^listener

Well, I was looking on what it would take to propogate that all the way up to
the WAKom level, which is still about three layers above that.

That's great to hear. Would navigating that file-system content be:
- done within a Seaside session (would be good, I believe)
- optionally embeddable within a Seaside component (iframe-ish)?
- otherwise free of overhead across fwd/back buttons etc.? (continuations?
component trees?)

Any guess on weeks/months/years until 2.9 is an option?

Thanks - Sophie

We have all the tools. It is just a matter of adding it. And since so
many people request it we will have to do it ;-)

The idea is to have a special FileLibrary that provides its resources
from a freely configurable file-system path, instead of using its
methods. It will be slow and inefficient (like the FileLibrary already
is), but it will make file serving easy. And, since it only builds on
top of Seaside, it will work with whatever Server you are using Kom,
Listener, Swazoo, FastCGI, ... on whatever Smalltalk platform you
want.

Yes, like the FileLibrary.

ESUG is usually a good time to announce things ... ;-)

I find myself doing this whenever I have a large script or file:

MyFileLibrary>>scriptJs
^ (StandardFileStream fileNamed: 'script.js')
contentsOfEntireFile

It makes no noticeable difference during development.

Do you mean something like this but better managed?

Zulq.

Personally, I like to go in the other direction. The point of this is to be able to work with the library files using tools more suited to other languages - Javascript, CSS and whatnot, yes?

I've hacked the Squeak FTP server[1] to serve the library methods as files. It #performs them for a download and recompiles them for an upload. Most text editors can handle editing remote files over FTP, so it works nicely.

Neat!

I got it loaded (after getting FastSocketStream) and can connect into "/"
with no directory contents.

How do I point it at MyFileLibrary?

I actually use it for OB-Web, which is not Seaside based, but it
probably wouldn't be much effort to adapt to WAFileLibrary. You can
see the code here:

http://source.wiresong.ca/ob/OB-Web-lr.56.mcz
http://source.wiresong.ca/ob/OB-Dev-FTP-cwp.3.mcz

FTPInternalFile wraps an instance of OBInternalFile, and implements
the protocol that the web server expects.

Ha!

I just spent about an hour trying to see my seaside app running in
Parallels on XP from other machines on my network, trying various network
configs and finally just booted into windows to try it from there. I still
couldn't see it except on localhost, and thought... "No, I didn't put that
Kom change in there..." and found:

pvtNewListener: backlogSize
"Create a new socket that listens on our port. The backlog is how many
simultaneous
connections to accept at the same time"

| listener |
listener := self socketClass newTCP.
self socketsToDestroy add: listener.
listener listenOn: portNumber backlogSize: backlogSize interface: #(127 0
0 1) asByteArray.
^listener

... from avi 2/5/2006 18:23

so it was only binding to localhost (127.0.0.1).

Very, very strange :)
