wrong script_name on dreamhost with flup

Description

I'm trying to use flup with Hatta on DreamHost, without much luck.

Radomir, do you have any idea where I'm going wrong? Here are some details for my simple test (in a Hatta page where I understand the markup, instead of Trac where I'm less confident).

bash$ # Which Hatta am I using...
bash$ hg log -r tip -R /home/rselzler2/HATTA/hatta-dev-D/

#flup.server.fcgi.WSGIServer(app).run() 
WSGIServer(app).run()

Some web sites suggest executing ./dispatch.fcgi
to help troubleshoot.
I've no idea what to expect, but this is what I happen to get.

The URL references "localhost", which seems wrong.
I was hoping for "pseis.org" (the interface parameter in dispatch.fcgi).

Regardless, Hatta seems to have executed and directory contents changed.

bash$ # What changed in my directory...

If I browse to  http://pseis.org then I see a directory list,
instead of Hatta.
I was hoping to see Hatta display an empty Edit page for Home.

If I browse to  http://pseis.org/dispatch.fcgi then I see Hatta,
which is encouraging :).
It displays an empty Edit page, titled ##Editing "dispatch.fcgi"##.
I was hoping the title would be ##Editing "Home"## :(

Yesterday was 14 hours of trial-error and I have bruises
around the head and shoulders to show for it.

Change History

comment:1 Changed 2 years ago by sheep

It looks like it's failing to get the SCRIPT_NAME and PATH_INFO from the request correctly for some reason. Something similar to why the "XXX" part was added in that dispatcher, except that the other way around. I suppose you can force the SCRIPT_NAME to "/dispatch.fcgi" and remove that part from the beginning of PATH_INFO... Something like:

def app(env, start):
    script_name = '/dispatch.fcgi'
    env['SCRIPT_NAME'] = script_name
    env['PATH_INFO'] = env['PATH_INFO'][len(script_name):]
    return wiki.application(env, start)

But this is a hack, I'd rather want to know why flup fails... -- Radomir Dopieralski

comment:2 Changed 2 years ago by Randy

Okay, I put those 5 lines in and tried it again...
The message printed by executing ./dispatch.fcgi changed:

bash$ ./dispatch.fcgi

If I browse to  http://pseis.org then, I see the directory listing.

If I browse to  http://pseis.org/dispatch.fcgi then
Firefox displays an error...

Redirect Loop

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

The browser has stopped trying to retrieve the requested item. The site is redirecting the request in a way that will never complete.

Does this provide a useful clue?

FYI

I installed flup 1.0.2 (instead of the newest 1.0.3) using

easy_install ~/PADM/stash/Flup/flup-1.0.2-py2.5.egg

The 1.0.3 version kept failing with...

AttributeError: 'CGIRequest' object has no attribute '_timeout'

-- Randy

comment:3 Changed 2 years ago by sheep

Sorry, I moved it here, it should be easier to talk about it.

OK, it looks like now it gets wrong PATH_INFO, so it redirects every time.
Out of curiosity, have you tried visiting http://pseis.org/dispatch.fcgi/ with the original script (yes, with a slash at the end)?

Can you paste the full traceback with flup 1.0.3? That might give me some idea why it fails...

Do you have access to logs on that server? If not, maybe we could use some hacked logger, like:

def app(env, start):
    f = open("/home/rselzler2/data-warp.com/poss_web/dispatch.log", "a")
    f.write("SCRIPT_NAME='%s'\n" % env['SCRIPT_NAME'])
    f.write("PATH_INFO='%s'\n" % env['PATH_INFO'])
    f.close()
    return wiki.application(env, start)

and then try it with various urls:

http://pseis.org/dispatch.fcgi
http://pseis.org/dispatch.fcgi/
http://pseis.org/dispatch.fcgi/aaa
http://pseis.org/dispatch.fcgi/aaa/bbb

comment:4 Changed 2 years ago by sheep

By the way, also try calling it "index.fcgi", maybe it would work.

comment:5 Changed 2 years ago by Randy Selzler <RSelzler@…>

That's one more rabbit you pulled out of Hatta's hat.

I removed the 5 lines and added a "/" to the URL... and it works !!!

That's another 6-pack of your favorite that I owe you.

Yes, I do have access to the server logs.

Are you interested in the other tests that you mentioned?
If not, lets close the ticket.
-- Randy

comment:6 Changed 2 years ago by sheep

Yes, it would be great to make it work without the slash, and to do that I would need to see what's happening with those two variables. Please try it if you have the time.

Thanks a lot, this gives me much better insight in what is going on. Seems like when you visit the fcgi script without the trailing slash, it reports SCRIPT_NAME and PATH_INFO to be identical. I guess I can test for that...

comment:9 Changed 2 years ago by sheep

But then, if you call your script "wiki.fcgi" and try to visit to visit page "wiki.fcgi" you will be sent to the home page instead :/

I think I'm getting somewhere, could you do a similar test, but add a third variable, REQUEST_URI? If that is provided, I would be able to reconstruct the broken PATH_INFO.

Replying to sheep:

Would you like the whole suite of tests again or a subset?

Just the dispatch.log file is enough, with visits to "dispatch.fcgi", "dispatch.fcgi/", and "dispatch.fcgi/something", thank you.

By the way, werkzeug already has a fixer for this case! Can you try this?


#!/usr/bin/python
# -*- coding: utf-8 -*-

import flup
import sys
# XXX Uncomment and edit this if hatta.py is not installed in site-packages
#sys.path.insert(0, "/path/to/dir/with/hatta/")
import hatta

config = hatta.WikiConfig(
    pages_path='/path/to/pages/', # XXX Edit this!
    cache_path='/path/to/cache/', # XXX Edit this!
)
config.parse_args()
config.parse_files()
config.sanitize()
wiki = hatta.Wiki(config)

import werkzeug
app = werkzeug.contrib.fixers.PathInfoFromRequestUriFix(wiki.application)

flup.server.fcgi.WSGIServer(app).run()
