luakit adblock installation fails [solved]

hello,

to activate some luakit adblock script i followed the wiki https://wiki.archlinux.org/index.php/Luakit#Adblock.
when restarting luakit, there seems to be a problem with my entry in the rc.lua.

luakit
./adblock.lua:515: attempt to index local 'fh' (a nil value)
[    1.064968] E: luakit: main:189: no windows spawned by rc file, exiting

any advices? thanks!

Re: luakit adblock installation fails [solved]

Did you put

require adblock
require adblock_chrome

inside the section labeled 'Optional user script loading', or did you put them at the beginning?

Re: luakit adblock installation fails [solved]

The variable 'fh' that the error says is nil is a file descriptor returned when opening ~/.local/share/luakit/adblock/subscriptions . Could you check whether that file exists and whether you have write permissions on it? And also whether the directory ~/.local/share/luakit/adblock exists?

Re: luakit adblock installation fails [solved]

well, the folder ~/.local/share/luakit/adblock exists, as i created it myself, but the only file in it is the easylist.txt, which i downloaded  from the arch wiki. it is the list of things to block, as far as i understand that. i changed permission to rwx, doesnt change anything. im not sure what you mean with subscriptions, but there is no file named like that!?
btw, when starting it as superuser, the browser can start normally, but i dont have access to my bookmarks, history and adblock commands.

Re: luakit adblock installation fails [solved]

Well when run by root, luakit would try to read the configuration files in /root/.config/luakit and then /etc/luakit when it wouldn't find them, so you wouldn't have adblock, and similarly for the history and bookmarks.

Does this throw an error (replace 'yourusername' with your user name)

 echo 'print(io.open("/home/yourusername/.local/share/luakit/adblock/subscriptions", "w"))' | lua

You mentioned the bookmarks and history do work, right? And there are files called history.db and bookmarks.db in ~/.local/share/luakit/ right?

Could you post your rc.lua?

Re: luakit adblock installation fails [solved]

the output of your code (would be nice if you explain its meaning, i guess its to check subscriptions, but i dont know what they are!?)is:

Re: luakit adblock installation fails [solved]

ah maybe ur right. i now changed the permissions in the easylist.txt file and moved it to the ~/.local/share/luakit folder (instead of ~/.local/share/luakit/adblock). now everything works well and i can use the adblock commands. BUT to activate adblock, i need to run in Normal mode, which means that my easylist.txt file has to be located in ~/.local/share/luakit/adblock. moving it back, same problem occurs.

Re: luakit adblock installation fails [solved]

the output of your code (would be nice if you explain its meaning, i guess its to check subscriptions, but i dont know what they are!?)is:

echo 'print(io.open("/home/lizzy/.local/share/luakit/adblock/subscriptions", "w"))' | lua
nil	/home/lizzy/.local/share/luakit/adblock/subscriptions: Permission denied13

The command just tries to open the file ~/.local/share/luakit/adblock/subscriptions for writing. When loading adblock.lua, luakit tries to do exactly that (the subscriptions file contains a list of blacklists, like 'easylist.txt'). The fact that the command returns a 'permissions denied' error means that the problem is that you don't have the permissions to create the file ~/.local/share/luakit/adblock/subscriptions, which makes luakit crash.

To fix that, run

chmod u+rwx ~/.local/share/luakit/adblock
chmod go+rx ~/.local/share/luakit/adblock
chmod u+rw ~/.local/share/luakit/adblock/*
chmod go+r ~/.local/share/luakit/adblock/*

which will give your user read/write/execute perissions on the adblock directory and read/write permissions on all of the files it contains, and your group and others permissions to read/execute (execute permissions on a directory are permissions to open the directory) the directory and read the files inside.

Re: luakit adblock installation fails [solved]

i did what you said, but nothing changed. the output of

 echo 'print(io.open("/home/lizzy/.local/share/luakit/adblock/subscriptions", "w"))' | lua

is still the same...maybe i should just get along without that adblock

Re: luakit adblock installation fails [solved]

Okay, what's the output of

ls -l ~/.local/share/luakit/

and of

touch ~/.local/share/luakit/adblock/subscriptions

Re: luakit adblock installation fails [solved]

first:

ls -l ~/.local/share/luakit/
total 108
drwxr-xr-x 2 root  root   4096 Jun  2 17:50 adblock
-rw-r--r-- 1 lizzy users  2048 Jun  2 09:42 bookmarks.db
-rw-r--r-- 1 lizzy users 68608 Jun  2 17:37 cookies.db
-rw-r--r-- 1 lizzy users 23552 Jun  2 17:47 history.db

and second:

touch ~/.local/share/luakit/adblock/subscriptions
touch: cannot touch ‘/home/lizzy/.local/share/luakit/adblock/subscriptions’: Keine Berechtigung

which is german and means that i dont have permission. as superuser it works but there is no output.

Re: luakit adblock installation fails [solved]

Okay

sudo chown -R lizzy:users ~/.local/share/luakit/adblock

That should give you all the Berechtigung you need.

edit: I added '-R' which is important.

Re: luakit adblock installation fails [solved]

yeah, finally! so the chown -R let the user lizzy operate on the folder adblock? why is it blocked by default?
anyway, thanks a lot!

Re: luakit adblock installation fails [solved]

chown changes the owner of files and directories, 'chown -R' changes the owner of directories and the files they contain. You may want to have a look at https://en.wikipedia.org/wiki/File_system_permissions .

My guess is that you created the adblock directory as root (using sudo), which would explain why root owned it instead of lizzy.
