Hm... helpful advice. I would have just recommended getting off of the internet altogether.

The thing is that it just shows the code on the browser, i think i have properly configured the httpd.config file, and yes i do have perl and i have a correct hashbang. Im using xampp on windows and i dont know what to do, any ideas ?

>>552
Ops i forgot the beginning:
Apache wont execute wakaba.pl

>>553
does this perl test script work?
http://wakaba.c3.cx/sup/kareha.pl/1109033191/4

>>547

Read through config.pl to find the various options for how threads are deleted. By default it happens by number of posts, not threads.

>>552

If code does not run, you have not properly configured the httpd.config file. Beyond that, it's not like we know how your server is set up. You really need to figure out that part yourself. Also, xampp is known to cause all kinds of problems.

>>554
It works with mod-perl activated, but with that i get this error with wakaba.pl:

[Wed Mar 25 14:06:30 2009] [error] Can't locate config.pl in @INC (@INC contains: . C:/xampp/perl/site/lib/ C:/xampp/perl/lib C:/xampp/perl/site/lib C:/xampp/apache) at C:/xampp/htdocs/wakaba/wakaba.pl line 16.\nBEGIN failed--compilation aborted at C:/xampp/htdocs/wakaba/wakaba.pl line 16.\n

Hi, I've got a problem with Oekaki.
I'm using Shi Painter, and everything is OK except one thing: after clicking upload in painting window it shows me a preview in a reply form, and in this preview picture has some constant name. So, my browser saves this picture to cash and next time, when I draw other picture, it shows me the previous one.
Thank you, and sorry for my english.

>>559

Configure Apache to send no-cache headers for all files in tmp/.

>>560
Hm... I tried:
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
It didn't work.
What am I doing wrong?

>>561

That's PHP code.

Look at example.htaccess.

>>562
In my .htaccess:
<IfModule mod_headers.c>
<Files *.html>
Header add Expires "Mon, 26 Jul 1997 05:00:00 GMT"
Header add Pragma "no-cache"
Header add Cache-Control "max-age=0; must-revalidate; no-cache"
Header unset Vary
</Files>
</IfModule>
Still don't work.

>>563
Check your page with wget -S http://blahblah/ or something such as Firebug to see if the headers are really being sent. Probably you don't have mod_headers enabled.

Well, all of a sudden my wakaba install is giving me this error:

Software error:

Malformed UTF-8 character (fatal) at wakautils.pl line 447, <FILE> line 3.

Line 447 is:

    $str=~s!([^\w/._\-])!"%".sprintf("%02x",ord $1)!sge;

which is part of:
sub clean_path($)
{

    my ($str)=@_;
    $str=~s!([^\w/._\-])!"%".sprintf("%02x",ord $1)!sge;
    return $str;

}

We've edited parts of our script and it's been working just fine for us for quite some time... this is a quite strange error and I'm hoping someone has a clue about what could be causing it. It happens when anyone tries to post or even when I try to rebuild caches. I'm assuming it will happen with anything that calls wakautils.pl.

>>565

Probably some kind of malformed UTF-8 in a filename or something similar.

>>563

You are sending those headers only for html files. Note the <Files *.html>.

Is there any option that allows Kareha threads to be numbered like that of Wakaba?

>>568

No.

Hi. when i'm trying to run wakaba.pl i get a 403 error.
permissions are set to 775.

I'd like to put google analytics in BBS system
Where should I put the code?

Sorry the bbs is Kareha

>>571-572
look in the include folder.

Sorry for sounding like a n00b, but how do I change the time zone settings? Currently it's five hours past my time zone.

>>574
DATE_STYLE in config.pl.
http and cookie use GMT, the rest use whatever the local time zone is set to on the server.
well, there is month that uses GMT as well, but that's just the month name and year, not the whole date and time.

actually, if i set up a kareha board anytime soon, i am so going to set DATE_STYLE to month.

> actually, if i set up a kareha board anytime soon, i am so going to set DATE_STYLE to month.

When I first ran wakaba I noticed that the user has to click the checkbox when they want to upload a file. I was wondering why you did this since the script runs fine without it? Also I think it makes the user input panel look a little less cluttered and confusing by taking it out.

>>577
You mean when they don't want to upload a file. That checkbox keeps people from posting a bunch of useless threads because they can't figure out how to reply.

I am attempting to run Kareha on free hosting server and so far i copied files and style to main directory and edited config.pl

When i try to run kareha.pl it shows me this:

Can't locate config.pl in @INC (@INC contains: . /etc/perl /usr/local/lib/perl/5.8.4

>>580

Dreamhost?

>>581
Yeah. Dreamhost private server. Kareha never did this to me before... but lately it's been taking up a large chunk of CPU and RAM.

I`m getting a
Software error:
CGI open of tmpfile: Permission denied
How do I change me temp dir to /wakaba/src/ or something?

>>582

Dreamhost has some kind of bug where flock() is broken and makes Kareha lock up waiting for a lock on log.txt that is never released.

I'm trying desparately to understand compile_template(), but that is some deep magic you got there, WAHa. It looks alien in comparison to the rest of the code, out of place.
Any chance of getting a commented version?

>>588

Yes, it's some pretty wacky magic, if I recall correctly. It was years since I wrote it, though, so I don't necessarily remember exactly how it works myself. I think I gave up on making it readable so I made it unreadable instead. Sorry about that.

It converts the template to Perl code, and turns off strictness so it can use name references to actually change global variables in as it enters and leaves scopes. The main trick is this:

$foo="bar";
$$foo=12;
print "$bar\n";

This will print "12". By setting variables this way, the <var> code can just evaluate whatever argument it is given as Perl code.

>>588

>>589
You're talking variable variables. Perl's use of references has always been somewhat magical. I'll figure it out, thanks!

>>590
Helpful.
It was hard to write, it should be hard to understand, eh?

>>591
They're not that difficult, just think of them as sort of like pointers.

I'm running a board and can't seem to increase the max number of pages past 2. I've increased considerably the max thread count and the max posts count, even changed the permissions on the folder and rebuilt cache, but I can't get any more pages. Help computah? :<

>>587
is it possible to disable the logging altogether?

>>594

You could put in a cron job to delete log.txt, I guess, but it would break deletion and break IP addresses on the admin page. The flock() itself is needed to avoid concurrent posts stomping on each other.

>>595
You couldd fake the file locking with a symlink and avoid the flock() call. Make a symlink somewhere (it doesn't even have to point anywhere, really), spin until the link succeeds, and unlink it when the script exits.

>>596
or you could find a host that doesn't break flock() like that or tell them to fix their broken shit.

>>597
I did that already. I was trying not to be pompous and elitist about it, though, instead preferring to help others in the hopes that they will on their own realize that the trouble that they have to go through in order to make decent use of a broken web host isn't worth the tiny price difference.

Trying to set up kahrea on nginx + fcgiwrap. The main board seems to work, but when I try clicking on an individual thread with a URL (in the format of http://www.whatever.com/board/kareha.pl/somenumber) it gives me a 404. I'm on a resource limited VPS and Apache takes up far too many resources for my liking, or else I'd simply use that instead.

This is the part of my nginx config dealing with the board.

location ~ ^/board/.*\.pl$  {
    include /etc/nginx/fastcgi_params;
    fastcgi_pass  127.0.0.1:10000;
    fastcgi_index index.html;
}

What am I missing?

>>587
Would it be possible to get any more details relevant to the problem with flock()? I only ask because I'm planning on complaining to Dreamhost and it would be good to have as much information as possible.

>>601

All I know is that suddenly flock() starts hanging on a specific file, and the only way to resolve it is to rename the file, and copy it back to the old location (so a new file is created, which can again be flocked() normally). Killing all running processes does not release that flock().

dreamhost has not caused issues with kareha or wakaba since 2006 on their regular hosting. maybe there's a problem with their PS service but that's a completely different beast. you should specify "dreamhost ps" in that case.

you don't even need their vps service unless you are getting around 5000 uniques * 10 pages/unique using kareha or if you are getting around 20000 or more a day with wakaba.

I don't know whether the fact that the config.pl should not be in UTF-8 amuses me or makes me want to puke.
Maybe it's my setup;

I ticked off the encoding and the template would display correctly
I ticked it on and the posts would display correctly.

And when I converted config.pl and some other files to ANSI everything came out fine.

Any tips? Should I leave it at that?

I notice that since I installed Wakaba 3.0.7 a while ago, an updated version has come out. What changes have been made? Is there a version history somewhere?

>>605

If you want it in UTF-8, you need to have use encoding 'utf-8'; at the top and no encoding; at the end.

>>606

Just bugfixes. It's been too long for me to remember what exactly all of them were, though.

Ive got perl showing the wakaba.pl page correctly, I just need to setup mysql. Anyone have exp with Mysql in Ubuntu? Or even linux for that matter?

Damn, sorry for the quad posts ... server would not reply.

>>613

Sorry, you said quad posts so I deleted three of them... Anyway, read http://wakaba.c3.cx/docs/docs.html.

i just " installed " kareha..

but when I visit mah page it only downloads kareha.pl instead of browsing it?

I've installed perl, and changed permissions. so idk : (

See the previous post.

>>614
I followed that completely. I go to <site>/kareha/kareha.pl, says the index.html does not exist. The guide says going to that file should make it.

I CHMOD'd the directory to 777 again, it made the index file fine. But, when I upload an image, it always says "No thumbnail".

Oh, I also can not ban anyone either.

Okay, in admin.pl, it shows their IP as ::ffff:<normal IPv4 address>

It will not let me ban IP addresses??

Okay, I fixed the IPv6 problem, yet I still can not ban IP addresses, nor get the thumbnails to work.

use constant CONVERT_COMMAND => '/usr/local/bin/convert'; # location of the ImageMagick convert command (usually just 'convert', but sometime a full path is needed)

That is the correct path, etc, it just does not work for making the thumbnails ??

Oh, also, all posts are "1 GETs"

>>621

>>622
Worst. Troll. Ever.

Quick question: How do we enable more than 11 pages of posts? Thanks.

Change the post limits?

Well, MAX_THREADS and MAX_POSTS are both set to zero in config.pl. Is it something else that I have to set?

MAX_AGE and MAX_MEGABYTES, I guess?

The Wakaba/Kahera support wiki has a SecretFeatures tiddle that says:

>Wakaba and Kareha have a couple of hidden options and features. Can you find them?

I havn't been able to find them and it is driving me mad. Somebody please put me out of my misery.

When trying to make or delete a post, kareha.pl usually forwards me to index.html without it being completely built. This results in a parsing error if xhtml is enabled. index.html is fine if refreshed. Any idea what's causing this?

>>628
they're probably referring to things like ^H and the other date formats that aren't documented in config.pl.

>>629

Sounds like some kind of very weird or broken server. The redirect isn't done before the file is completely written to disk.

>>627

I never found MAX_AGE in config.pl (running 3.1.3). It's in there now, let's see what it does.

I basically want to be able to archive everything if possible.

You can test things in the test thread.

>>630
No offence but I hope you are wrong because that is dissappointing.

Please, help me with these problems ;_;

>>636

• does your web server support .htaccess?
• what are the permissions on the thumbnail directory?
• are there any files in the thumbnail directory?
• all posts or just the first one in each thread? if it's the first one in each thread, it's supposed to be like that (assuming you're using kareha, not wakaba).

I think I need a perl guru to help me with this mystifying problem. I run a wakaba image board and the admins want to have #admin after their posts, which is fair enough.I got it working by adding this at line 144 of futaba_style.pl (308):

<if !$email><if $name eq 'NAME'><if $trip eq 'TRIP'><span class="admin">#Admin#</span></if></if></if>
<if $email><if $name eq 'NAME'><if $trip eq 'TRIP'><span class="admin">#Admin#</span></if></if></if>

This worked flawlessly on a test site, but when I added the code to my live site it works fine on some boards and not at all on others. Even if I copy futaba_style.pl from a board which is working it still refuses to work. Even more baffling is one particular board which inserts #Admin# for posts that already exist, but not new posts!?!

I only have very basic programming knowledge but I don't even see how the last scenario is even possible. If the script recognises a name and trip combo and inserts #Admin# in one post, how can it not recognise the exact same name and trip combo in another post. Baffling. Obviously there is something more to this beyond my knowledge so if someone can point me in the right direction I'd be supper appreciative.

>>638

I have no idea what causes the problem, but mabe you should first just remove the outermost <if> statements and just have the code in there once. There's little point in doing it twice like that.

Also, you can combine several tests into <if $name eq 'NAME' and $trip eq 'TRIP'> to get rid of another if statement. Making the code simpler might help in figuring out what is going wrong

I am trying to install Wakaba on a shared hosting server. When I try and run wakaba.pl to get the html files it just trys to download the file and not run it. I asked my host about this and they said the files have to be in the cgi bin folder or something. Can someone please explain how to get this working X__X thank you.

>>637
My server is running Lighttpd, Ubuntu 9.04. It supports .htaccess, I think.

It is chmodded 777. All access.

Not to begin with, but when someone makes a post, it makes a 0-Byte file there, as if it tried to thumbnail and failed.

Why is it SUPPOSED to be like that? And no, it is all posts. Why does the first image not get thumbnailed though?

>>641

> My server is running Lighttpd

Wakaba has only been tested on Apache. If you want to run it on anything else you're on your own. There will be problems. This is not recommended unless you really know what you're doing, and it seems that maybe this isn't the case.

>>342
To fix the manager post problem, edit futaba_style.pl:

Search the file for ADMIN_POST_TEMPLATE. This should be found around line 590. There is some shit about form fields. Leave the "hidden" type alone. Starting on line 602 is the shit about postblocks for name, email, subject,(submit button) and comment. Leave the submit button alone. Change the name="whatever" to name="field1". Do this for name, email, subject, and comment; as in, change them to field1, field2, field3, and field4. In the order they are.

Also, change it so it looks like this:
use constant ADMIN_POST_TEMPLATE => compile_template(MANAGER_HEAD_INCLUDE.q{

<div align="center"><em><const S_NOTAGS></em></div>

<div class="postarea">
<form id="postform" action="<var $self>" method="post" enctype="multipart/form-data">

>>643

That should be fixed in the latest version.

Problem with oekaki:

After painting my image, uploading it and writing RIGHT captcha, i see error about wrong captcha. What it can be?

I'm wondering if there's anyway to grab the subject from the first post in a thread, and to reflect it within "futaba_style.pl".

>>641-642
I've been running Wakaba and Kareha both on lighty for quite some time on a couple of different systems (I have tried it with OS X Tiger, FreeBSD, and Arch Linux, and had no problems)

The only snag is that lighty doesn't support htaccess files, so you'll have to translate the relevant stuff to its own config format. Not that hard to do, just tell it that .pl files should run with perl. You don't need to enable the fastcgi module (in fact, don't enable it) You might additioanlly want to fiddle with the expires headers if you find you're getting old copies of the pages served after posting.

As for permissions, if you set up execwrap or something similar you can get it running without the (highly insecure!) chmod 777. It's easier to configure than Apache's suexec, imo.

I have a bit of a question about Wakaba: I want to create an upload board like 4chan's flash board. However, I just installed it and it functions like a regular imageboard (like you'd see on any other part of 4chan). Is there a way I can get Wakaba to mimic 4chan's flash board in terms of appearance and function, and if not what should I be using?

> As for permissions, if you set up execwrap or something similar you can get it running without the (highly insecure!) chmod 777.

or you can just set the owner of the directories to the user that the scripts run as, and then set the permissions to 755.

>>649
That's still not secure, and requires root on some systems in order to "give away" the permissions to the web server. In fact it's probably a worse choice because it could potentially lull you into a false sense of security where you're actually in the same circumstance as before.

The issue is that other processes on the server can open up config.pl and scrape (and perhaps change) your admin password, either because it's readable and writable to all, or because they're all running as the same user. If two people have access to the web server and the server is running all scripts under the same user id, all script files are accessible to all users regardless of what else you do to them.

It's a shame that the Apache developers reacted so irrationally and so strongly against suexec, because it solves many problems and creates very few.
