# Installation/Setup questions

Ikiwiki creates a .ikiwiki directory in my wikiwc working directory. Should I
"svn add .ikiwiki" or add it to svn:ignore?

I'm trying to install from scratch on a CentOS 4.6 system.  I installed perl 5.8.8 from source and then added all the required modules via CPAN.  When I build ikiwiki from the tarball, I get this message:

    rendering todo/calendar_--_archive_browsing_via_a_calendar_frontend.mdwn
    *** glibc detected *** double free or corruption (!prev): 0x0922e478 ***
    make: *** [extra_build] Aborted

I'm kind of at a loss how to track this down or work around it.  Any suggestions? --Monty

# Installation of selected docs (html)

The latest release has around 560 files (over 2MB) in html.

Any suggestions or ideas on limiting what html is installed?

For example, I don't see value in every ikiwiki install out there to also install personal "users" ikiwiki pages.

For now I copy ikiwiki.setup. And then use pax with -L switch to copy the targets of the symlinks of the basewiki.

I was thinking of making a list of desired documents from the html directory to install.

# Installation as non-root user

I'd like to install ikiwiki as a non-root user. I can plow through getting all the 
perl dependencies installed because that's well documented in the perl world,
but I don't know how to tell ikiwiki to install somewhere other than / --BrianWilson

# Upgrade steps

I upgrades from 1.40  to 2.6.1. I ran "ikiwiki --setup" using my existing ikiwiki.setup configuration.
I had many errors like:

    /home/bsdwiki/www/wiki/wikilink/index.html independently created, not overwriting with version from wikilink
    BEGIN failed--compilation aborted at (eval 5) line 129.

and:

    failed renaming /home/bsdwiki/www/wiki/smileys.ikiwiki-new to /home/bsdwiki/www/wiki/smileys: Is a directory
    BEGIN failed--compilation aborted at (eval 5) line 129.

Probably about six errors like this. I worked around this by removing the files and directories it complained about.
Finally it finished.

> [[tips/switching_to_usedirs]] for details. --[[Joey]]

>> I read the config wrong. I was thinking that it showed the defaults even though commented out
>> (like ssh configs do). I fixed that part. --JeremyReed

My next problem was that ikiwiki start letting me edit without any password authentication. It used to prompt
me for a password but now just goes right into the "editing" mode.
The release notes for 2.0 say password auth is still on by default.

> It sounds like you have the anonok plugin enabled?

>> Where is the default documented? My config doesn't have it uncommented.

The third problem is that when editing my textbox is empty -- no content.

This is using my custom rcs.pm which has been used thousands of times.

Now I regenerated my ikiwiki.cgi again (no change to my configuration,
and I just get an empty HTML page when attempting editing or "create".

Now I see it created directories for my data. I fixed that by setting 
usedirs (I see that is in the release notes for 2.0) and rerunning ikiwiki --setup
but I still have empty pages for editing (no textbox no html at all).

> Is IkiWiki crashing? If so, it would probably leave error text in the apache logs. --[[TaylorKillian]]

(I am posting this now, but will do some research and post some more.)

Is there any webpage with upgrade steps?

--JeremyReed

My followup: I used a new ikiwiki.setup based on the latest version. But no changes for me.

Also I forgot to mention that do=recentchanges works good for me. It uses my 
rcs_recentchanges in my rcs perl module.

The do=prefs does nothing though -- just a blank webpage.

> You need to figure out why ikiwiki is crashing. The webserver logs should
> tell you.

I also set verbose => 1 and running ikiwiki --setup was verbose, but no changes in running CGI.
I was hoping for some output.

I am guessing that my rcs perl module stopped working on the upgrade. I didn't notice any release notes
on changes to revision control modules. Has something changed? I will also look.

> No, the rcs interface has not needed to change in a long time. Also,
> nothing is done with the rcs for do=prefs.

>> Thanks. I also checked differences between 1.40 Rcs plugins and didn't notice anything significant.

--JeremyReed

Another Followup: I created a new ikiwiki configuration and did the --setup to 
create an entirely different website. I have same problem there. No prompt for password
and empty webpage when using the cgi.
I never upgraded any perl modules so maybe a new perl module is required but I don't see any errors so I don't know.

The only errors I see when building and installing ikiwiki are:

    Can't exec "otl2html": No such file or directory at IkiWiki/Plugin/otl.pm line 66.

    gettext 0.14 too old, not updating the pot file

I don't use GNU gettext on here.

I may need to revert back to my old ikiwiki install which has been used to thousands of times (with around
1000 rcs commits via ikiwiki).

--JeremyReed

I downgraded to version 1.40 (that was what I had before I wrote wrong above).
Now ikiwiki is working for me again (but using 1.40). I shouldn't have tested on production system :)

--JeremyReed

I am back. On a different system, I installed ikiwiki 2.6.1. Same problem -- blank CGI webpage.

So I manually ran with:

    REQUEST_METHOD=GET QUERY_STRING='do=create&page=jcr' kiwiki.cgi

And clearly saw the error:

    [IkiWiki::main] Fatal: Bad template engine CGI::FormBuilder::Template::div: Can't locate CGI/FormBuilder/Template/div.pm

So I found my version was too old and 3.05 is the first to provide "Div" support. I upgraded my p5-CGI-FormBuilder to 3.0501.
And ikiwiki CGI started working for me.

The Ikiwiki docs about this requirement got removed in Revision 4367. There should be a page that lists the requirements.
(I guess I could have used the debian/control file.)

> There is a page, [[install]] documents that 3.05 is needed.

>> Sorry, I missed that. With hundreds of wikipages it is hard to read all of them.
>> I am updating the download page now to link to it.

I am now using ikiwiki 2.6.1 on my testing system.

# Excellent - how do I translate a TWiki site?

I just discovered ikiwiki quite by chance, I was looking for a console/terminal
menu system and found pdmenu.  So pdmenu brought me to here and I've found ikiwiki!
It looks as if it's just what I've been wanting for a long time.  I wanted something
to create mostly text web pages which, as far as possible, have source which is human 
readable or at least in a standard format.  ikiwiki does this twice over by using 
markdown for the source and producing static HTML from it.

I'm currently using TWiki and have a fair number of pages in that format, does
anyone have any bright ideas for translating?  I can knock up awk scripts fairly
easily, perl is possible (but I'm not strong in perl).

> Let us know if you come up with something to transition from the other
> format. Another option would be writing a ikiwiki plugin to support the
> TWiki format. --[[Joey]]

> Jamey Sharp and I have a set of scripts in progress to convert other wikis to ikiwiki, including history, so that we can migrate a few of our wikis.  We already have support for migrating MoinMoin wikis to ikiwiki, including conversion of the entire history to Git.  We used this to convert the [XCB wiki](http://xcb.freedesktop.org/wiki/) to ikiwiki; until we finalize the conversion and put the new wiki in place of the old one, you can browse the converted result at <http://xcb.freedesktop.org/ikiwiki>.  We already plan to add support for TWiki (including history, since you can just run parsecvs on the TWiki RCS files to get Git), so that we can convert the [Portland State Aerospace Society wiki](http://psas.pdx.edu) (currently in Moin, but with much of its history in TWiki, and with many of its pages still in TWiki format using Jamey's TWiki format for MoinMoin).
>
> Our scripts convert by way of HTML, using portions of the source wiki's code to render as HTML (with some additional code to do things like translate MoinMoin's `\[[TableOfContents]]` to ikiwiki's `\[[toc ]]`), and then using a modified [[cpan HTML::WikiConverter]] to turn this into markdown and ikiwiki.  This produces quite satisfactory results, apart from things that don't have any markdown equivalent and thus remain HTML, such as tables and definition lists.  Conversion of the history occurs by first using another script we wrote to translate MoinMoin history to Git, then using our git-map script to map a transformation over the Git history.

Clicking on an old "?" or going to a create link but new Markdown content exists, should not go into "create" mode, but should do a regular "edit".

# Various ways to use Subversion with ikiwiki

I'm playing around with various ways that I can use subversion with ikiwiki.

* Is it possible to have ikiwiki point to a subversion repository which is on a different server?  The basic checkin/checkout functionality seems to work but there doesn't seem to be any way to make the post-commit hook work for a non-local server?

> This is difficult to do since ikiwiki's post-commit wrapper expects to
> run on a machine that contains both the svn repository and the .ikiwiki
> state directory. However, with recent versions of ikiwiki, you can get
> away without running the post-commit wrapper on commit, and all you lose
> is the ability to send commit notification emails.

> (And now that [[recentchanges]] includes rss, you can just subscribe to
> that, no need to worry about commit notification emails anymore.)

* Is it possible / sensible to have ikiwiki share a subversion repository with other data (either completely unrelated files or another ikiwiki instance)?  This works in part but again the post-commit hook seems problematic.

--[[AdamShand]]

> Sure, see ikiwiki's subversion repository for example of non-wiki files

# Regex for Valid Characters in Filenames

# Upgrade steps from RecentChanges CGI to static page?

# News site where articles are submitted and then reviewed before posting?

I am considering moving a news site to Ikiwiki. I am hoping that Ikiwiki has a feature where anonymous posters can submit a form that moderators can review and then accept for it to be posted on a news webpage (like front page of the website).

> Well, you can have one blog that contains unreviewed articles, and

Also it would be good if the news page would keep maybe just the latest 10 entries with links to an archive that make it easy to browse to old entries by date. (Could have over a thousand news articles.)

> The inline plugin allows setting up things like this.

Plus users be able to post feedback to news items. If anonymous, they must be approved first. I'd prefer to not use normal "wiki" editor for feedback.

Any thoughts or examples on this? Any links to examples of news sites or blogs with outside feedback using ikiwiki?

Thanks --[[JeremyReed]]
