I have a strange problem with editing any page after its first SVN commit.
I'm not sure whether it's my ikiwiki backport bug or my misunderstanding
how ikiwiki works.
Assume that I have Foo page with any content and I want to put there link
to Bar page and next create the page. I do following steps:
-
Click Edit link on Foo page
-
Put the link to Bar page there and commit it by clicking "Save Page"
button
The Bar page is rendered correctly and now I can see ?Bar link. The URL
in the address bar of my browser is
http://my.host.com/wiki/foo.html?updated
- Click ?Bar link
Now I can see textarea for editing of page. It's empty, of course.
The page doesn't exists in my SVN repo yet and my Apache server knows
noting about it:
$ find /my/ikiwiki/src/dir/ -type f -name bar.mdwn
$ find /my/ikiwiki/dst/dir/ -type f -name bar.html
- Add some initial content and click "Save Page" button
to commit changes
The Foo page also is rendered correctly and now I can see what I wrote.
The URL in the address bar of my browser is
http://my.host.com/wiki/bar.html?updated
The page was added to the SVN repo and my Apache is able to serve it now:
$ find /my/ikiwiki/src/dir/ -type f -name bar.mdwn
/my/ikiwiki/src/dir/bar.mdwn
$ find /my/ikiwiki/dst/dir/ -type f -name bar.html
/my/ikiwiki/dst/dir/bar.html
- Change the content of Bar page by clicking Edit link
I can't do it, because the textarea is empty again. I have to run
ikiwiki --setup ikiwiki.setup command by hand to rebuild the page.
Then I can edit it.
Where is my mistake?

It's not clear which Edit link you clicked in step 5. Is it the link on
the new page, or the old link back on page Foo that you clicked on before
to create Bar? It would also be good to see the URL you're at in step 5.
--[[Joey]]
It was Edit link on new Bar page, of course. The URL in step 5 was
http://my.host.com/wiki/ikiwiki.cgi?page=bar&do=edit.
I've forget to add in my previous post that $pagesources{$page}
(cgi_editpage subroutine of /usr/share/perl5/IkiWiki/CGI.pm file)
doesn't exist in step 5. It exists after rebuilding all ikiwiki
pages by hand.
BTW, where does ikiwiki store information about rendered pages?
Is it /my/ikiwiki/src/dir/.ikiwiki/ directory?
--Pawel
Well, the missing %pagesources value explains the symptom for sure.
ikiwiki stores its state in .ikiwiki/index, and that should include
info about the new page you've created, including the source file for
it, which is where the data in %pagesources comes from.
It sounds to me like somehow, when you commit a change to svn by
saving the page, it rebuilds the wiki, but does not update the index
file. Maybe it's crashing before it can save the index file. Or maybe
it's possibly be misconfigured, and updating a different index file in
a different copy of the source? You should be able to figure out what's
going on my looking at how the index file changes (or not) when you
create the new page. --[[Joey]]
I've checked that my ikiwiki really doesn't touch .ikiwiki/index file
when I create and save a new page. In error.log file of my Apache2
server I can't see any "Permission denied" messages, but I suspect
that a reason of my problem can be the bad access permissions:
root@my.host:/my/ikiwiki/src/dir# ls -ld .ikiwiki/
drwxrwsr-x 2 www-data src 4096 2007-01-11 10:00 .ikiwiki/
root@my.host:/my/ikiwiki/src/dir# cd .ikiwiki/
root@my.host:/my/ikiwiki/src/dir/.ikiwiki# ls -l
razem 48
-rw-rw-r-- 1 www-data src 17353 2007-01-11 10:00 index
-rw-rw-r-- 1 www-data src 0 2007-01-11 10:17 lockfile
-rw------- 1 www-data src 24576 2007-01-11 10:17 sessions.db
-rw------- 1 www-data src 0 2006-11-15 14:45 sessions.db.lck
-rw------- 1 www-data src 404 2007-01-08 10:24 userdb
What do you think about it? Does it look good? My ikiwiki runs
under control of Apache2 server and it's configured to run
as www-data user and www-data group. --Pawel
It's a bit weird to run ikiwiki as www-data. This means that www-data
can write to your subversion repository? And the svn post-commit hook
also runs as www-data? It certianly could be some permissions issue
that is not being reported properly. --[[Joey]]
No, my SVN post-commit hook runs as root (uid) and www-data (gid).
Only root user and src group have write permissions to my SVN repo.
Could you please show me your permissions for repodir, srcdir
and destdir and how runs your Apache server? --Pawel
Ugh, root? My permissions setup is simple, ikiwiki runs as a single
user, and that same user can commit to the svn repo and write to
all files. --[[Joey]]
What's your user? Please show me result of ls -ld dir for
directories above :) --Pawel
All my directories are 755 joey:joey. --[[Joey]]
Thanks! But I have another situation: a multiuser system and a few
ikiwiki commiters. --Pawel
Joey, I think I've just fixed the permission, but my ikiwiki still
doesn't update my .ikiwiki/index file. Could you please explain me
when ikiwiki calls saveindex() subroutine? My ikiwiki doesn't do it
when I create a new page and save it or when I update and save
a existing page. It does it only when I run
ikiwiki --setup ikiwiki.setup and I'm desperated...
BTW, where should I store my ikiwiki.setup file? It must be placed
under $srcdir/.ikiwiki/ directory or it doesn't matter?
Does ikiwiki.cgi wrapper know where the ikiwiki.setup file
is stored? --Pawel
Sorry I am not indenting for my reply (in my browser the responses are very narrow.)
I also had problem with no webpages getting generated via the CGI unless I ran ikiwiki to regen manually.
I can't find the discussion here about in the ikiwiki website though. I think it was removed and now I can't find it in the history.
My problem was caused by not having a revision system defined, so it defaulted to subversion (but I didn't have that installed).
As for your .setup file you can put it anywhere. I don't think the CGI knows where it is at because its settings are set in the "wrapper".
In my case, my setup file is in a different home and owned by a different user than the CGI or my generated website. By the way, I also don't keep my .ikiwiki private directory in my source directory by setting wikistatedir (which doesn't seem to be documented).
--[[JeremyReed]]
Never mind about indentation, Jeremy! :) Thanks a lot you're interested in
my problem and you try to help me.
I use RCS backend and store my ikiwiki sources in SVN repo. Here is my SVN
related settings:
rcs => "svn",
svnrepo => "/var/lib/svn/ikiwiki",
svnpath => "trunk/pages",
I've noticed the following piece of code in /usr/share/perl5/IkiWiki/CGI.pm
file (cgi_editpage() subroutine):
# save page
page_locked($page, $session);
my $content=$form->field('editcontent');
$content=~s/\r\n/\n/g;
$content=~s/\r/\n/g;
writefile($file, $config{srcdir}, $content);
if ($config{rcs}) {
# Here is RCS stuff
# ...
}
else {
require IkiWiki::Render;
refresh();
saveindex();
}
# The trailing question mark tries to avoid broken
# caches and get the most recent version of the page.
redirect($q, "$config{url}/".htmlpage($page)."?updated");
As you can see ikiwiki calls saveindex() subroutine if rcs variable
is not defined. I don't understand it, because in this way ikiwiki
doesn't update my .ikiwiki/index file. Joey, could you please
enlight me here ;)
BTW, I also noticed wikistatedir variable in the ikiwiki code
and I couldn't find any information about it in ikiwiki docs :) --Pawel
