Hi, list!

I'm trying to install Sputnik 8.08.13 on my Ubuntu box as per this guide:

http://sputnik.freewisdom.org/en/Installation

This step fails:

$ ./bin/lua -lluarocks.require -e 'require("sputnik").setup()'

Stack traceback below. Note how it looks for 1.4.0-1, and I have
1.4.1-1 installed by rocks.

/opt/sputnik$ ls rocks/luafilesystem/
1.4.1-1

I've used rocks command  from the mentioned wiki page:

$ ./bin/luarocks --only-from=http://sputnik.freewisdom.org/rocks/earth
install sputnik 8.08.13

Traceback from require("sputnik").setup():

I suspect this should be some conflict with my existing luarocks
installation. I've copyed luafilesystem 1.4.0-1 from it to the Sputnik
rocks/ directory, and that fixed this error.

I am glad you got it working, but I am wondering what caused the
problem in the first place. Perhaps it's not so much the different
installations of Lua Rocks as the different _versions_?  What was your
existing luarocks installation?

BTW, if already have a lua+luarocks and your version of LuaRocks is
reasonably recent, and you are not interested in using Xavante (or are
willing to configure it by hand), you can install sputnik with just

  luarocks --only-from=http://sputnik.freewisdom.org/rocks/earth
install sputnik 8.08.13
  lua -lluarocks.require -e 'require("sputnik").setup()'
  mkdir wiki-data && chmod -R a+rw wiki-data

This should give you all you need to use sputnik with cgi. Everything
before that is just an easy way to install lua, luarocks and xavante
in such a way that they all work together.

(Of those three lines, only the first one really does installation.
The second line just creates a sputnik.cgi file.)

That was 0.4.something. I deleted it trying to solve my other problems
with Sputnik (see below), so I can't say for sure, sorry.

I'm interested in Xavante, but it does not work for me (see below).

Thank you.

I have removed my other luarocks installation, removed Sputnik, and
installed it from scratch. I have these problems (and had them before
reinstall):

1. When I run Sputnik with Xavante, all edits fail. The post request
from my browser either "hangs" or browser complains that "server broke
connection". I have double checked permissions on my wiki-data
directory, all is OK.

2. When I run Sputnik as CGI on Apache, save works fine, but I have no history.

My sputnik.cgi file:

#! /bin/bash /opt/sputnik/bin/wsapi.cgi
require('sputnik')
require("lfs")
lfs.chdir("/opt/sputnik/wiki-data/")

return sputnik.new_wsapi_run_fn{
   VERSIUM_STORAGE_MODULE = "versium.git",
   VERSIUM_PARAMS = { '/opt/sputnik/wiki-data/' },
   BASE_URL       = '/cgi-bin/sputnik.cgi',
   PASSWORD_SALT  = '<censored>',
   TOKEN_SALT     = '<censored>',
}

$ ls -la wiki-data/
total 20
drwxrwxrwx  4 agladysh agladysh 4096 Dec 31 19:14 .
drwxr-xr-x 11 agladysh agladysh 4096 Dec 31 19:10 ..

-rw-r--r--  1 www-data www-data  300 Dec 31 19:21 index.lua
drwxrwxr-x  2 www-data www-data 4096 Dec 31 19:18 sputnik

/opt/sputnik/wiki-data$ git status
# On branch master

# Initial commit

# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#	index.lua
#	sputnik/
nothing added to commit but untracked files present (use "git add" to track)

I'm on Ubuntu Gutsy (7.10, Server).

$ git --version
git version 1.6.1

Please advise me how can I debug these issues. The
kepler/log/xavante.log contains only Xavante start messages.

Unfortunately, I don't know what this means. Xavante really isn't my
area of expertise.

You mean specifically when using versium.git? Did the default storage
option work?

Make sure that wiki-data/.git is writeable by www-data. This should
have been mentioned in the documentation, and I just added it.

(And I'll look into why this isn't generating an error, as it really should.)

This is with git as a the repo? My guess is that there's a subprocess
hanging... can Xavante answer another connection while the browser is hung?

We have a Sputnik installation under Xavante running fine on
luarocks.orgwith the default backend, so something in the git backend
is my suspect
here.

I tried again to reproduce it, and I cannot. Can anyone else?

I am on Ubuntu 8.10 now, but I am pretty sure I tested it on 7.10 back
in July...

Does this happen with a fresh install?
