Good heavens! Did you post to phpwiki-talk? I haven't done any development
on PhpWiki in over a year, just doing the releases. Jeff Dairiki is the
principle architect over the last two years; I'm sure they can pinpoint
the problems very quickly!

Steve, Thanks for getting back to me. Jeff and others - our company has vigorously adopted PHPWiki in part due to my strong recommendations and prior experience working with this wiki. We've encountered a number of issues with PHPWiki, however, the most serious by far being corruption of large documents. When we take a large wiki node, edit it, preview it, and save it, whole paragraphs are duplicated in the result. This is not operator error - it's happened several times, even from cut-and-pasting from a text editor window! I'm unclear as to what is causing this corruption, but it has rendered the wiki all but unuseable for large documents. There are other somewhat less serious issues, too -- when a wiki node has a large table in it (>200 rows) it simply freezes up the machine. PHP times out after 30 seconds and cancels the page load. "Document History" does not appear to work correctly for documents that have been edited a large number of times. (It does not show the most recent changes made.) Also, our listing of RecentChanges seems to have stopped about seven days ago. While these are all issues I'd like to see resolved, without the first -- namely fixing the corruption issue, we're going to have to switch to a different wiki. Have any of you guys seen this? Is this a misconfiguration? Is it a bug with an easy fix? We're using MySQL 3.23.49 as the backing store, PHP 4.3.1 with MySQL, Apache 2.0.43, and PEAR v1.50. This is using PHPWiki 1.3.4. One patch that you might want to know about (tiny) is in lib/config.php, where in order to support Apache2, this line: if (php_sapi_name() == 'apache') got changed to this line: if (php_sapi_name() == 'apache' || php_sapi_name() == 'apache2filter') Could it be something about our Apache2 interactions that's messing things up?

If you could provide a samlpe doc, that would be helpful. It's probably too large to send to the list, so you could send it to me directly and I could forward it, or else you could dump it into the demo or test sites: http://phpwiki.sourceforge.net/test/index.php/HomePage (the nightly build) http://phpwiki.sourceforge.net/demo/ (is probably closer to 1.3.4) > There are other somewhat less serious issues, too -- when a wiki node has a > large table in it (>200 rows) it simply freezes up the machine.

I'd wager the database has proprietary info, otherwise I'd try to get a mysqldump that one of us could set up and test.. ~swain > > ----- Original Message ----- > From: "Steve Wainstead" <sw...@pa...> > To: "David E.

Is there an example at a publicly accessable URL? New-style.

No, but that Apache process goes bonkers, consuming huge amounts of CPU. PHP terminates it after 30 seconds, giving up. > Are you sure that things are happy on the MySQL front? > (Run (my)isamchk on the tables. Any filesystem errors?

I will continue trying to reproduce this issue in a consistent fashion to see what is breaking. -david |

After I changed the columns in the tables to LONGTEXT, then I'm able to deal with a ~210 KiB page here: http://www.gimpster.com/wiki/CommandLine Before that change, the text on the page got truncated to 2^16 bytes which is the capacity of a TEXT column in MySQL. I guess a MEDIUMTEXT column with a capacity of 2^24 bytes = 16 MiB would suffice for most pages. -- Martin Geisler My GnuPG Key: 0xF7F6B57B See http://gimpster.com/ and http://phpweather.net/ for: PHP Weather: Shows the current weather on your webpage and PHP Shell: A telnet-connection (almost :-) in a PHP page.

Yes, you're right... I checked the log in CVS and it says that it's always been MEDIUMTEXT... Thinking back, then I must have changed it when I was playing with using full-text indexes in MySQL. They are (unfortunately) only allowed on TEXT columns. By the way, a full-text index worked well for me, giving me relevant hits for my searches. -- Martin Geisler My GnuPG Key: 0xF7F6B57B See http://gimpster.com/ and http://phpweather.net/ for: PHP Weather: Shows the current weather on your webpage and PHP Shell: A telnet-connection (almost :-) in a PHP page.

(I vaguely remember stories about some browsers having issues when the data in the textareas gets to be larger than a certain size (32K or 64K).) > There are other somewhat less serious issues, too -- when a wiki node > has a large table in it (>200 rows) it simply freezes up the machine. Is this a "new-style" table or an old-style table (via the OldStyleTable plugin)? Is there an example at a publicly accessable URL? Or can you send me some example wiki-text which will trigger the bug? (Do you really mean "freezes up the machine"?

I've never seen nor heard of behavior like that before. Are you sure that things are happy on the MySQL front? (Run (my)isamchk on the tables. Any filesystem errors? Enough disk space?) > Have any of you guys seen this? I haven't. > if (php_sapi_name() == 'apache' || php_sapi_name() == 'apache2filter') (This has been fixed in CVS.) > Could it be something about our Apache2 interactions that's messing > things up? I doubt it, but I don't have an alternative theory either, so who knows? |

Hello, first... thanks for this software!.. I like the theme stuff and the easy to install stuff. Now.. problems: after a server software update (berlios.de swiching to the latest php version) my wiki has crash. this is the error msg: lib/DbaDatabase.php:32: Fatal[256]: driver initialization failed ------------------------------------------------------------------------ Fatal PhpWiki Error lib/DbaDatabase.php:32: Fatal[256]: driver initialization failed I am working off line with the gdbm file to rescue the wiki data ( 9MB of data ) but is hard because my localhost apache+php dont support gdbm files, I suspect. I want to: * fix the error or * rescue the data Something help will be wellcome. --Tei telejano.berlios.de/wiki3 |
