On my FUDforum 2.7.3 installation a forum datadump apparently hangs while processing the index table. I've let it cook all night, but in the morning it's still stuck on the fud26_index. I'm getting a little nervous about not having a current backup, so I hope someone has a solution. Here's the datadump screen display for your perusal:

It is a very large table as you can tell almost 800,000 records, so it will take some time to dump to disk. I suspect your browser has simply timed out before the request had a chance to complete. I'd recommend running the script via command line for a large forum.

I don't suppose optimizing the index is going to speed up the dump...

As I feared, the datadump done via the Admin Control Panel didn't finish completely:

-rw-r--r-- 1 root nobody 120651776 Oct 5 00:02 FUDforum_05_10_2006_12_00.fud.gz

gzip: FUDforum_05_10_2006_12_00.fud.gz: unexpected end of file

Which command-line script are you referring to, specifically? I don't see any likely candidates in the /FUDforum/scripts directory.

Nevermind, I had overlooked adm/admdump.php.

Actually, I ended up making a copy named "clidump.php" and then uncommented the "fud_use('adm_cli.inc', 1)" and "cli_execute('')" lines in it.

Executing the script from the command line, the datadump finished in (ha!) record time -- and the key word is "finished." Furthermore, it passed gzip's integrity check. I'm going to look at the code to see how tough it would be to suppress all the unneeded HTML code that's generated by the script.

But right now I'm in the process of importing the datadump into a new FUDforum installation. It's been chugging away for about twenty minutes, which makes me nervous about what will happen to the import process if my browser times out. I examined admimport.php to see if it could also be executed from the command line, but guess not. Anyway, I'm keeping my fingers crossed that the import finishes without incident.

BTW, have I mentioned how much I love FUDforum? If not, let me correct the oversight here and now.

UPDATE: The data import has been cooking for a few hours now. I see that the user table has been modified, but none of the others; the messages and files directories seem to be receiving some files; and df indicates FUDforum's file system is growing, albeit sloooowly. The browser displays a page that's blank except for the Admin Control Panel's menu on the left, but at least the browser hasn't timed out yet. Sure wish I could execute admimport.php from the command line instead; it would be less likely to cause an aneurysm.

To heck with using the browser interface to import. The command line is the way to go. I copied admimport.php to cliimport.php and modified it with the --

define('recovery_mode', 1);
$_POST['path'] = '/path/to/dumpfile';

-- method, and fired if off in background mode. Now we're getting somewhere! So far, it has processed 350,000 queries in about an hour and a quarter, so it's not quite half-way finished yet, but it's processing to beat the band. I'm guessing it will take about three hours or so to import the entire 800,000 record dump.

At some point, if no one else has done so, I'll modify both clidump.php and cliimport.php to output non-HTML text to the terminal.

For large, time-consuming operations, running scripts via the command line can't be beat.

I increased max_execution_time to 28800 seconds in php.ini. Hope that will solve the problem. But now I have to hack cliimport.php to force it to resume the import at 490000 so as to not duplicate the effort. I guess I'm only screwed and blued, but not tatooed just yet.

In regard to resuming the import where it left off, if possible, here's fud26_index's last record:

+---------+---------+--------+
| id | word_id | msg_id |
+---------+---------+--------+
| 1302073 | 22 | 9354 |

I've been pretty much flying solo in this thread, but if anyone has any help to offer it would be welcomed.

Well, increasing the execution time in the script via set_time_limit(0) will probably ensure a complete run. If it still does not work you can forgo the forum's built-in data dump and simply use mysql dump for database info and tar for forum's files.

Thanks, I'll try that. But first, I'll restore the SQL tables and FUDforum/files and FUDforum/messages directories to their pristine, pre-import state...

Okay, ready to execute...

And there are a bunch more like that. Hope those are benign messages. The funny thing is, the earlier run that timed out at 6000 seconds didn't have those errors. Here's the output from that run:

The warnings you are seeing can be ignored, they are caused by the fact that you are bypassing authentication system and running the script on the command line.

No progress indicator from import? You may want to add flush() calls to force PHP to dump output to screen right away and not buffer it in memory.
