Where exactly is "Public"?

Hi all,

it's surely a stupid question, but I cannot seem to answer myself. I
have a copy of my demo working fine on my laptop (served by swazoo)
but the apache proxy on the official site for some reason now cannot
serve files anymore (it will serve "everything packed in Iliad" fine,
though). The page is duly made and served (so gst is definitely up and
running) but without images, css etc. I made a find throughout the
server to see where the few things it gets were coming from, the
results are quite puzzling.

this is all my stuff plus:

/root/.st/cache/git__github.com__%2FNicolasPetton%2Filiad.git/More/UI/Public/images/arrow_down.png

I can change *any* of these and it doesn't affect the output. So it
must come from somewhere else. Hmmm where?

To add some spice, there seem to be something REALLY weird around, as
a grep finds

     aPage head javascript src: '/javascripts/layermagik.js'.
/home/apache/ambaradan/Ambaradan-Application/Application/AmbaradanApplication.st:
     aPage head javascript src:
'/javascripts/jquery-ui-1.7.2.custom.min.js'.

All these files get a 404 not found msg, BUT

/home/apache/iliad/Core/Buildables/ILApplication.st:    aPage head
javascript src: '/javascripts/jquery132min.js'.
/home/apache/iliad/Core/Buildables/ILApplication.st:    aPage head
javascript src: '/javascripts/no_conflict.js'.

This are loaded as expected.

Weird, huh?

I think Public comes straight from the .star file that you loaded
Iliad from.  Make sure it is there also on the server and not only on
the development machine (it is needed even if Iliad is in the GST
image).

If it's related to a proxy server, the proxy configuration (for the vhost)
would be quite helpful in debugging this.

This is the .conf file for the site. It worked okay until I upgraded
Iliad and gst.

My impression, exactly...

Iliad arrived on the server by
gst-package -t ~/.st --download iliad

Hi Bèrto,

In Iliad 0.8, ILFileHandler doesn't deal with file directories directly,
this is now handled by subclasses of ILDirectory.

You can serve files from a .star, from the image or from a directory,
see the abstract ILDirectory class, and the two concrete classes
ILDiskDirectory and ILMemoryDirectory.

You can use it as follows:

Iliad.ILFileHandler addDirectory: (Iliad.ILDiskDirectory new
directory: aDirectory

This works with both star files and directories. For a .star, you can
do:

Iliad.ILFileHandler addDirectory: (Iliad.ILDiskDirectory new
        directory: (PackageLoader packageAt: 'somePackage') directory /
'Public')

Note that if there is a Public directory when you start Iliad it will be
automatically added to the served directories of the file handler, see
Core/postLoad.st:

Eval [
    (Directory image / 'Public') exists ifTrue: [
        ILFileHandler addDirectory:
           (ILDiskDirectory new
                directory: (Directory image / 'Public');
                yourself)].
    ILFileHandler addDirectory:
        (ILDiskDirectory new
    directory: (PackageLoader packageAt: 'Iliad-Core') directory /
'Public';
    yourself).
]


Even if this is nice for development, I wouldn't use it in production.
Instead I would serve all static files with a front-end web server like
Apache.


Cheers,
Nico

I would change the proxy directives with rewrite rules:

# Proxy to Iliad if the requested file doesn't exist
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ http://127.0.0.1:8080/$1 [proxy,last]


If you need more complex rewrite rules, also note that it's possible to
add rewrite rules on the Iliad part too:

Iliad.ILUrlBuilder addRewriteRule: [:string |
        string copyReplacingAllRegex: 'foo' with: 'bar']

You can add as many rewrite rules as you want, they will be applied in
the order you added them.

For example, if you want to serve iliad examples without the
'/examples', ie the counter example would be accessed at '/counters'
instead of '/examples/counters', you can do something like:

Iliad.ILUrlBuilder addRewriteRule: [:string |
string copyReplacingAllRegex: '^\examples' with: '']

and in the vhost config file:

RewriteRule ^/(.*)$ http://localhost:8080/examples/$1 [proxy,last]

Cheers,
Nico

Hi!

well, you opened an entire planet before my eyes :) I *love* it... it
will make browser based local apps deployment a breeze! But you are
right, much better to serve stuff with apache for a public website :)
I'll make sure I understand this stuff *very* well :)

I should really write some documentation...

Hi again,

I moved all static files to apache and it definitely loads *much*
quicker. Just one remaining problem. How do I over-ride graphic stuff
from the iliad .star package? I have made (for example) my own
ajax_loader, and I see it declared in Iliad's source in this line of
./Public/javascripts/iliad.js:

"<img src='/images/ajax_loader.gif'/></div>");

Now, I could change the line to

"<img src='http://myfileserver.org/images/ajax_loader.gif'/></div>");

and recompile but this is surely not what you had in mind... I suppose
there must be a much cleaner way to do it, right? I suppose I can
redirect all input from the .star to the fileserver, in one go, can I?

(including iliad.js, and everything you need).

Then you can remove all served directories from Iliad:

Iliad.ILFileHandler directories: {}

Note to myself, I should probably add methods to ILFileHandler to make
this easier...

Hello, I have a problem with images and css files not being loaded, as
well (though the problem is different as I understand).

I'm on Squeak (Iliad installed via Metacello). When I try to do, for
example:

(ILFileHandler new) fileContentsFor: '/images/iliad.png'.

This error comes:

MessageNotUnderstood: ByteString>>copyWithRegex:matchesReplacedWith:

on:

fileSelector := self convertToSelector: (self adjustPath: aString).

line of #fileContentsFor: method of ILMemoryDirectory. Is
#copyWithRegex:matchesReplacedWith: method supposed to come with
Squeak?

Hmm, me too. I guess it's installed in Pharo-dev images, but not in
Pharo-core.
