Topic: Converter: InvPB2 -> PunBB1 b3

I've uploaded a public beta to PunRes. Would be happy if people could test it for me. Only use this to help me make the converter! If there's some bugs, I won't help anyone by making a fix for an already converted forum.

Not being able to login into PunBB after the converter is done is not a bug. It's just not possible to convert the passwords beqause InvPB and PunBB handles tha passwords differently, like this:

InvPB:
$hash = md5( md5( $salt ) . md5( $password ) );

PunBB:
$hash = md5( $password );

Read this thread for more info about the password-problem.

Note: BACKUP your database before using it!

InvPB2-PunBB1_beta1.rar

Could you propose the same archive but compressed with a free compression format, or at least with zip ? (I can't use it by now, I don't have WinRAR)

OK, let's do the test now :-)

It seems I have to first migrate from IPB 1.1.2 to IPB 2 :-(

Yes. Seems pointless to make a converter from an old version of IPB... they've probably changed alot in the database between the versions.

:-/ Even after searching, I don't know how to migrate from my IPB 1.1 to 2.0 !

I think I'll simply debug phpBB to punBB converter...

phpBB?

I thought they shipped an updater with their install package... I'll look closer at it.

Edit: Found some info in a topic at the IPB forum:

There will be an upgrade script for 1.3 to 2.0 when version 2 reaches a stable release.

They seems to release v.2.0.0 soon (It's only "Public Development Release" now), and then you can convert to v2.0.

Yes... the converter from IPB 1.1 to phpBB 2.0.x exists and is easy to use. Once I have phpBB 2.0 database, I use phpBB to punBB converter (see problems I encountered in Converter: PhpBB2 -> PunBB1.1 topic)

Oh, nice solution! It should work fine yes :)

Edit: I've missed your huge post, I'll look at it right away. Rewriting some parts of the PhpBB->PunBB converter (found much better solutions for a converter when I made the IPB -> PunBB-converter :)).

Edit2: Done with the other converter... see it's topic for more information-

New release out... made some minor changes. The converter now adds a lock-file to prevent users from running it again if the admin forgets to remove the files.

Will the password conversion problem ever be solved? Or is it impossible?

It is impossible.

Is it better to write a mod than having all users get a new password (through the "I forgot my password"-feauture)? (It's times like this I miss a poll-system...)

Re: Converter: InvPB2 -> PunBB1 b3

There's a problem with the installer if you don't have PunPoll installed. Cange line 20 in _start.php to:

@$db->query($sql);

I'm uploading a new ver to punres when it's up again.

Odd. I've never got that error. It's only a notice, so it should work anyway. You don't got anymore error-message?

Rickard: Might the notice depend on any missing ' in the variable maybe?

    if ($db_error)
        $GLOBALS[db]->close();

Re: Converter: InvPB2 -> PunBB1 b3

Yes, that's the problem. It's fixed in 1.2. However, that's not the problem aleksei is experiencing. The notice is actually an error message in the error handling function :) He'll have to enable DEBUG mode and try again.

Re: Converter: InvPB2 -> PunBB1 b3

Rickard, after enabling DEBUG mode it look`s like :

An error was encountered
File: z:\home\localhost\www\forum\conv\_topics.php
Line: 32

PunBB reported: Unable to save to table: topics
Database reported: You have an error in your SQL syntax near ' 'Farch', 0, '4' )' at line 10 (Errno: 1064)

i apologize that`s the problem with my ipb database...

Re: Converter: InvPB2 -> PunBB1 b3

Am I correct in thinking that the password hashes from IPB 1.x would be compatible with PunBB?

If so, a good solution for those converting from IPB 1.x to PunBB via the IPB 2 upgrade could be to grab the password hashes before upgrading to IPB 2, and drop them back into PunBB after the conversion. I think that'd work?

Re: Converter: InvPB2 -> PunBB1 b3

Yes, if IPB 1.x only hashes the password, and no salt
