[Phpwiki-talk] problem with phpwiki using dba.

[Adam S. <la...@sp...>]

hey.

hopefully i'm just being stupid and it's an obvious problem because i
really want this to work.  i'm a relative newbie with php but haven't had
many problems with other programs i want to work.  i'm using debian linux,
php4.0.4pl1 and apache 1.3.14.

phpwiki works great when i set it like this in lib/conifig.php:

$WhichDatabase = 'file';

but as soon as i try to set it to 'dba' i get this error:

Warning: Variable passed to reset() is not an array or object in /var/www/devel.spack.org/phpwiki/lib/dbalib.php on line 52
Warning: Variable passed to each() is not an array or object in /var/www/devel.spack.org/phpwiki/lib/dbalib.php on line 53
WikiFatalError
Cannot open database 'wiki' : '/tmp/wikipagesdb', giving up.

the web server does have permissions to write there because it works just
fine in file mode so i'm not sure what to do.  i'm wondering if debian has
done something a little weird, it breaks all the php extensions into
seperate packages so i only have the core, imap and gd ones installed.
does dba need to be listed in an "extension=xxx" line in my php.ini file?

regardless any help would be much appreciated.

thanks,
adam.

First, I hope you don't name the file directory and the DBM files the
same... that's just an initial guess.

There was a post on the list recently about a special config option, and I
think it was about Debian but I can't find it in the list archives... a
module had to be loaded by PHP at runtime.

Also, did you compile the package yourself or use get-apt (or whatever
Debian uses?) You might try setting it to 'dbm' instead of 'dba' and see
if that works. I was wondering if dba_* support was compiled in or not.

Let me know if any of that helps and we'll try again if not.

i was under the impression that phpwiki would create the dbm files itself.
it creates the flat files itself?  if that's not what you mean then i
don't understand sorry ...  here's the relevant section of my config file:

   $WhichDatabase = 'dba'; // use one of "dbm", "dba", "mysql",
                           // "pgsql", "msql", or "file"

   // DBM and DBA settings (default)
   if ($WhichDatabase == 'dbm' or $WhichDatabase == 'dba' or
       $WhichDatabase == 'default') {
      $DBMdir = "/tmp";
      $WikiPageStore = "wiki";
      $ArchivePageStore = "archive";
      $WikiDB['wiki']      = "$DBMdir/wikipagesdb";
      $WikiDB['archive']   = "$DBMdir/wikiarchivedb";
      $WikiDB['wikilinks'] = "$DBMdir/wikilinksdb";
      $WikiDB['hottopics'] = "$DBMdir/wikihottopicsdb";
      $WikiDB['hitcount']  = "$DBMdir/wikihitcountdb";

was there a solution?  i know debian pretty well but i can't find any
documentation exactly where the dba module is.  the docs say it's compiled
in and it looks like it is from running strings on the php binary but it's
more then possible that i have to enable something in a config file or
something.

i used apt-get.  when i try dbm i get a blank page in my browser with just
this when i view source:

Aha. Well, this is some problem with either the dba_ support or the dbm
support; you see, the dbm* functions are deprecated in PHP4.0 in favor of
the dba_* functions, which are a more generic interface. This has caused
us a lot of install problems.

Did you try setting your database type to "dbm" and see if that works? If
not, the next step is to set it to "dba" again, and edit dbalib.php and
remove the '@' symbol from the dba_open() call:

   function OpenDataBase($dbname) {
      global $WikiDB; // hash of all the DBM file names

      reset($WikiDB);
      while (list($key, $file) = each($WikiDB)) {
         while (($dbi[$key] = @dba_open($file, "c", "gdbm")) < 1) {

------------------------------^ right here

            $numattempts++;
            if ($numattempts > MAX_DBM_ATTEMPTS) {
               ExitWiki("Cannot open database '$key' : '$file', giving
up.");
            }
            sleep(1);
         }
      }
      return $dbi;
   }


With the '@' removed you will get a verbose error message telling us what
the problem is.

err, this was with it set to dbm.  with it set to dba i get the original
error i reported:

Warning: Variable passed to reset() is not an array or object in /var/www/devel.spack.org/phpwiki/lib/dbalib.php on line 52

now i get this:

Yes, this is just PHP saying it got a variable that should be an array
but was not.

I can't find any reference to this error on the PHP site... perhaps you
could email the maintainer of the PHP package for Debian? I wish I could
offer more but at the moment I'm stumped.
