[9fans] Can't copy create.html into wikifs

[9fans] Can't copy create.html into wikifs

[jrmu]

Greetings,

I'm attempting to set up wikifs but running into some permissions problems.

First I copy the sample wiki:

mkdir /sys/lib/wiki.plan9
{cd /sys/lib/wiki && tar cp .}|{cd /sys/lib/wiki.plan9 && tar xT}
mkdir -p /usr/web/plan9/wiki/

Then in /cfg/plan9/cpurc, I add these two lines:

wikifs -p 666 -s wiki.plan9 -a tcp!*!wiki /sys/lib/wiki
ip/httpd/httpd -d plan9.host.ircnow.org -n /cfg/plan9/namespace.httpd -w /usr/web/plan9/

Then in /cfg/plan9/namespace.httpd, I add this line:

mount -bc '#s'/wiki.plan9 /usr/web/plan9/wiki

I create the directories as needed:

mkdir -p /usr/web/plan9/wiki/

Now the default wiki seems to be lacking create.html, so I downloaded it to
/usr/bootes/create.html and attempt to copy it:

mount -bc '#s'/wiki.plan9 /usr/web/plan9/wiki
cp /usr/bootes/create.html /usr/web/plan9/wiki/

But I get this error:

cp: can't create /usr/web/plan9/wiki//create.html: '/usr/web/plan9/wiki//create.html' create prohibited

I do not know why because the permissions seem fine:

cpu% cd /usr/web/
cpu% ls -l
d-rwxrwxr-x M 68 bootes sys 0 Feb 14 22:17 plan9
d-rwxrwxr-x M 68 bootes sys 0 Feb 14 13:01 sys
cpu% cd plan9
cpu% ls -l
d-rwxrwxr-x M 68 bootes sys 0 Feb 14 13:10 sys
d-rwxrwxr-x M 68 bootes sys 0 Feb 15 20:35 wiki

Here are the permissions of /sys/lib/wiki and /sys/lib/wiki.plan9:

d-rwxrwxr-x M 68 sys    sys      0 Feb 15 20:21 /sys/lib/wiki
d-rwxrwxr-x M 68 bootes sys      0 Feb 15 20:21 /sys/lib/wiki.plan9

If you have any ideas, I would be grateful. Thanks in advance for the
help.

Ok, figured out. Don't mount #s/wiki.plan9, you are not mean to do that.

Re: [9fans] Can't copy create.html into wikifs

So, this is what David do on 9p.io (ftpfs 9p.io to see)
create index.html, create.html, about.html in /usr/web/wiki/plan9
httpd will mount #s/wiki.plan9 before /usr/web/wiki/plan9

I guess wikifs' files are virtual, and wikifs is a file server, so it is free to answer whatever it want to your create requests.
Also, look at 9p.io's wiki index too, how is it produced?

By the way, there is an issue in the 9p.io wiki that anyone editing it with acme will notice. I mailed David but haven't got a response.

Re: [9fans] Can't copy create.html into wikifs

[jrmu]

Greetings,

Were you able to get create.html working so you can create a new page?

The directory I specified was correct for my setup, I wanted to have it
in /usr/web/plan9/wiki not /usr/web/wiki/plan9.

It is also necessary to mount '#s'/wiki.plan9, otherwise the wiki won't
load, so this command should be correct:

mount -bc '#s'/wiki.plan9 /usr/web/plan9/wiki

My main problem is why file creation/writing isn't allowed in
/usr/web/plan9/wiki

Re: [9fans] Can't copy create.html into wikifs

[jrmu]

Greeetings,

So I followed your advice and added create.html to /usr/web/plan9/wiki before
mounting '#s'/wiki.plan9. However, I wasn't able to actually post anything.
When I attempt to create a new wiki page, I end up with this error message:

Object not found
The object /wiki/plan9/new_wiki_page/index.html does not exist on this server.
errstr: '/usr/web/plan9/wiki/plan9' file does not exist
uri host:
header host: plan9.host.ircnow.org
actual host: plan9.host.ircnow.org

So it seems the write failed.

Greetings,

Nevermind, I got it to work. The new page is actually created at
wiki/new_wiki_page/index.html.

Thanks for your help.

Thank you, this script worked for me:

{
        echo '<p>Wiki Index</p>'
        echo '<p>Index of wiki pages:</p>'
        sed 's/([0-9]*) (.*)/<br> * \<a href="\2"\>[\2] (\1)\<\/a\>/' /sys/lib/wiki.plan9/d/map | sort
