Re: [Phpwiki-talk] Installation problems

aha,
very interesting handlers and bugs.
thanks a lot. what's your exact php version?

I try to test the "db4" issue, which seems to be the nearest fit.
It looks like a simple file permission problem.
Do you have write permission to "pages/wiki_pagedb.db4" ?

Another idea is this:
Try to change the dba_open mode from "c" to "c-" or "cl".
This is a known PHP bug, which I only circumvented for windows.
Maybe it's a locking problem for linux also.

I fixed it in lib/DbaDatabase.php:

// PHP 4.3.x Windows lock bug workaround: 
http://bugs.php.net/bug.php?id=23975
if (isWindows() and (strlen($mode) == 1)) {
     $mode .= "-"; // suppress locking
}
while (($dbh = dba_open($this->_file, $mode, $this->_handler)) < 1) {

but you can also try it in lib/WikiDB/backend/dba.php:
-      if (!$db->open('c')) {
+      if (!$db->open('c-')) {
