Hi all, I've done a few searches for answers online, but the archives for PHPWiki list at sourceforge appear to be down (along with the entire search capability at sf.net).... Anyway, I was happily running PHPWiki 1.3.x on RedHat 9.0 for a long time and finally got fed up with the lack of updates. So, I upgraded to Fedora Core 3. I discovered that the default installation of PHP didn't include GDBM support, so I installed the php-4.3.11-2.4.src.rpm, edited the spec file to add the --with-gdbm and --enable-dba options, recompiled, and reinstalled PHP. restarted Apache, and I'm now getting the following error message: lib/DbaDatabase.php:54: Error[256]: dba_open(/home/alanh/html/wiki/pages/pagedb.gdbm,c): Driver initialization failed for handler: gdbm: File open error file: /home/alanh/html/wiki/pages/pagedb.gdbm mode: c handler: gdbm I don't think this is a permissions problem: $ ls -l /home/alanh/html/wiki/pages/pagedb.gdbm -rwxrwxrwx 1 apache apache 1024021 Apr 13 08:46 /home/alanh/html/wiki/pages/pagedb.gdbm* Any suggestions as to what to try? Again, I apologize if this has been answered in the past. -alan -- Alan Hoyle - al...@un... - http://www.alanhoyle.com/ "I don't want the world, I just want your half." -TMBG Get Horizontal, Play Ultimate. |

Hi Reini,
I'm looking at the version of DbaDatabase.php that was included in
phpwiki-1.3.11_rc1 and I don't understand quite what you mean.
I see the following code fragment on lines 46-53:
46 if (check_php_version(4,3,0) and (strlen($mode) == 1)) {
47 // PHP 4.3.x Windows lock bug workaround: http://bugs.php.net/bug.php?id=239 47 75
48 if (isWindows()) {
49 $mode .= "-"; // suppress locking, or
50 } elseif ($this->_handler != 'gdbm') { // gdbm does it internally
51 $mode .= "d"; // else use internal locking
52 }
53 }
54 while (($dbh = dba_open($this->_file, $mode, $this->_handler)) < 1) {
55 if ($watchdog <= 0)
56 break;
57 flush();
58 // "c" failed, try "w" instead.
59 if (substr($mode,0,1) == "c" and file_exists($this->_file))
60 $mode = "w";
But I don't see what I should change in here in order to make it work. I
don't see where $mode ever gets set to "c" and how I can make any changes
to make it work....

There are only two changes which affect you.
The first is not important:
* Randomizing (a la Ethernet collision handling) competing locks.
$secs = 0.5 + ((double)rand(1,32767)/32767);
sleep($secs);
$watchdog -= $secs;
This changed the loop.
* Second, the change from "c" to "w" if the first "c" fails,
in line 59-60
gdbm errors are all about locking and its improper handling within
php. gdbm itself works marvelous.

Perhaps I should be a bit more detailed in my report:
----- error page -----
Fatal Error:
lib/DbaDatabase.php:56: Error[256]:
dba_open(/home/alanh/html/wiki/pages/pagedb.gdbm,w): Driver
initialization failed for handler: gdbm: File open error
file: /home/alanh/html/wiki/pages/pagedb.gdbm
mode: c
handler: gdbm
lib/DbaDatabase.php:56: Error[256]:
dba_open(/home/alanh/html/wiki/pages/pagedb.gdbm,w): Driver
initialization failed for handler: gdbm: File open error
file: /home/alanh/html/wiki/pages/pagedb.gdbm
mode: c
handler: gdbm
----- end error page -----
It's not giving me a failover to the "w" in the first place. If I put
a "$mode =3D "w" right before the "while" statement, I get the same
error except with w's instead of c's in the "mode" line.
