SchoolTool

Virtual host, memory usage and versions

Asked by Daniel Bünzli

I now managed to install schooltool from the tarball. Here are a few questions :

1) Being on a shared host I'm unable to specify a virtual host as described in the documentation to install schooltool under a prefix. Is there something I can do about that by adding something in the instance's paste.ini or schooltool.conf ? Basically my host allows me to specify a path (e.g. /schooltool) and it redirects all the traffic through this prefix on the instance. For the time being I was only able to use / as a path, since schooltool doesn't know that it served under a prefix.

2) My host limits my memory usage to 256Mb. Is that enough for a few years and a few hundreds students ?

3) To actually install the whole system from the tarball I had to tweak the [package] section to add all the gradebook, journal and intervention. I ended up with dev versions of these (especially a non-fonctional journal). Under [versions] I constrained all the components to version 2.1.0 and the journal now works. Is there a short and standard procedure to install a given stable release ? I understand schooltool is supposed to be installed via apt-get but for those of us on shared hosting it would be nice to have some kind of standard way to install a stable release (or at least precise instructions) Did I miss something ?

Thanks.

P.S. Other than that, the extensive user manual is very nice and clear.

You could try filling paste.ini with something like this:

[composite:main]
use = egg:Paste#urlmap
/schooltool = schooltool

[app:schooltool]
use = egg:schooltool#main
config_file=schooltool.conf

[server:main]
use = egg:Paste#http
host = 0.0.0.0
port = 80

Thanks, I tried that but the _wsgi server_ responds with a 404 saying that / does not exists (same if I try directly with /calendar).

Besides, nothing shows ups in instance/log/web-access.log. I tried to turn on event logging and dev mode. But it's all very quiet.

Any ideas ?

Daniel

P.S. That's what I tried:

[composite:main]
use = egg:Paste#urlmap
/fp/schooltool = schooltool

[app:schooltool]
use = egg:schooltool#main
config_file=schooltool.conf

[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 25910

Try looking at 127.0.0.1/fp/schooltool/calendar

This url map does not specify what lies under /, so you'll get 404. But /fp/schooltool should work fine.

Also, 127.0.0.1 does not look right... Shouldn't it be 0.0.0.0? http://book.schooltool.org/remote.html

No, to explain, my shared host tells me to serve my app on localhost on a port it assigns me. He then routes all the traffic on my domain for a given prefix, for example.org/fp/schooltool/*, there.

To sum up. If I try to use the regular paste.ini with the following :

[app:main]
use = egg:schooltool#main
config_file=schooltool.conf

[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 25910

This works perfectly fine but I'm only able to access schooltool from the root of my domain name, example.org/. If I try to specify the same setup, that is access via example.org/ but via urlmap :

[composite:main]
use = egg:Paste#urlmap
/ = schooltool

[app:schooltool]
use = egg:schooltool#main
config_file=schooltool.conf

[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 25910

This also work. But as soon as in [composite:main] I try a different path from / I get this html

> curl http://example.org/fp/schooltool
<html>
<head><title>Not Found</title></head>
<body>
<h1>Not Found</h1>
<p>The resource could not be found.
<br/>/
<!-- defined apps: (None, '/fp/schooltool')
SCRIPT_NAME: ''
PATH_INFO: '/'
HTTP_HOST: 'example.org' --></p>
<hr noshade>
<div align="right">WSGI Server</div>
</body>
</html>

Best,

Daniel

I think the problem must be that the my shared host doesn't seem to setup a correct PATH_INFO when it does its URL routing. I didn't find anyway to override that from the config files, is there any ? Otherwise the question may be closed.

Best,

Daniel

Pinning all versions to 2.1.0 is a good solution.

A good way to get a compatible set of stable versions is to change one of base.cfg file from flourish to 2.1, which is the last stable version

[buildout]
extends = http://ftp.schooltool.org/schooltool/2.1/versions.cfg
versions = versions
find-links =
    http://ftp.schooltool.org/schooltool/2.1/

There is an alternative way to get all the modules, https://launchpad.net/schooltool.release. Checkout the stable version of this umbrella project

$ bzr branch lp:schooltool.release/2.1 schooltool
$ cd schooltool
$ make
# schooltool modules and dependencies will be downloaded as tarballs
$ make run

There is no tarball of schooltool.release. Should make one...
