Install Bug? setup-config.php?step=2

Maybe something here:
Headers Already Sent FAQ question

I am having the same problem.

Runing MySql ver 5.0.15
PHP ver 4.3.10-16
Apache2 2.0.54

test.php bundled with php reports
MySQL_api 4.0.24
Before running the wordpress install.php script, the expected MySql database was created. This is a new install, there are NO TABLES CREATED YET! No instructions for doing so, none have been discovered. Looking through the wordpress scripts, I haven’t yet found where these tables will be created. In wp-settings.php these table names are listed, but no columns defined/declared.

No previous version of wordpress has ever been installed, so no existing database/tables present. The blank database expected in the 5 minute install was created, but no tables. (This is on a home LAN, not public.)

Running the install script with wp-config.php properly edited to provide hostname, user, password, database name results in “Can not connect to database error”. MySQL user tables with correct privileges are present. Both “OLD_PASSWORD”, and “PASSWORD” have been tried. WordPress can not connect with either password format.
(Yes, I am sure that MySql is running.)

Running the install script with wp-config.php not present, setup-config.php properly detects the missing file, and offers to create one. After filling in the necessary entries for hostname, user, password, database, and “submit”ing the data, setup-config.php fails at step 2 with this same error.

Warning: Cannot modify header information – headers already sent by (output started at /storage/Debian/wordpress/wp-admin/setup-config.php:22) in /storage/Debian/wordpress/wp-includes/wp-db.php on line 308

I have seen the previous tip about white space, missing php tags, etc. Looking at setup-config.php I’m having trouble decrypting the nested code blocks in the three cases present.

Note Appended: Looking at the scattered headers coded into various php scripts it occurs to me that it might be a better coding practice to have ONE FUNCTION that builds/outputs the required html header, and that ONE FUNCTION be called in each case when a header is appropriate, rather than having headers hand coded into various scripts multiple times.
Just a thought.

It’s whitespace outside of either
<?php
or
?>

inside that whitespace doesn’t matter.

@podz this shouldn’t be a whitespace issue as the behaviour is also present in a ‘clean’ install of 2.1 replacing both setup-config.php & wp-db.php

The wp-db.php is the culprit as far as I can tell, the issue is with function bail – Just wraps errors in a nice header and footer

If I comment the following lines the error disappears:

header( 'Content-Type: text/html; charset=utf-8');

Something similar here https://trac.www.ads-software.com/ticket/2409

Apparently something to do with failed mysql_connect, or mysql_open call.
setup-config will not connect to mysql version 5.0.15 on ‘localhoast’, but when I specify a different host, on my home LAN, which is running mysql version 4.1.16, everything works!

the host (on my LAN), that I wanted wordpress installed on apparently has a conflict between php4, and myqsl ver 5.

It is not a wordpress issue, other than failing to handled the failed open, or connect in wp-db properly.

It’s kinda interesting to see wordpress storing its documents on a host different from the host which is serving the documents to the user, and the host that is actually running the php scripts!

This is now fixed thanks to davidhouse patch
