Issues with SMF 2.1

(1/2) > >>

Oldiesmann:
Upgraded a site I help out with to SMF 2.1 last night and am working on setting up the gallery now, but keep running into issues...

First, the code is expecting the template file to be named Gallery2.template.php but the one that comes with it is Gallery2.1.template.php. Renaming this file fixes this issue.

The second more pressing issue is with the queries to show stuff. We're running MariaDB 10.0.36.

In the query beginning on line 659 of Gallery2.php, it complains about columns not being in "GROUP BY" until I add every column except m.real_name to the GROUP BY clause.

Once I get that done it finally displays the gallery but then I run into the same issues with the query for the recent comments ("'<database>.p.commenttotal' isn't in  GROUP BY"). I'm not sure exactly what the issue is, as I run SMF Gallery Pro on a different server (with MariaDB 10.2) without problems, though that's on SMF 2.0. I can get around that by simply not displaying most commented/recent items on the gallery index - attempting to add p.commenttotal to the GROUP BY clause doesn't seem to work (I just get that same error about p.commenttotal).

If I go to Gallery Stats, I get another error about 'm.real_name' not being in GROUP BY.

SMFHacks:
For template issue it should have inserted a setting into the settings table "gallery_smfversion" and set it to 2.1 which is excuted on the dohooks.php
That will then make the systme choose to load the 2.1 template.

The group by issue is caused by this ONLY_FULL_GROUP_BY setting enabled in the database server

I attempt on install to detect it and then run this query and when the gallery is in use
SET sql_mode=(SELECT REPLACE(@@sql_mode, 'ONLY_FULL_GROUP_BY', ''))




Can you attach your updated Sources/Gallery.php want to see the changes made. Will see if can those added.

Oldiesmann:
The template issue seems to be that it sets "gallery_smfversion" to "2.1beta" instead of "2.1". If I change it to just "2.1" it works fine.

I can attach Gallery.php, but basically the changes to make it work with the FULL GROUP BY setting involve modifying queries with GROUP BY clauses and adding a bunch of columns to GROUP BY. I'll see if I can make SMF set the SQL mode for every query it runs so I don't have to do that.

Oldiesmann:
Did some more digging and it looks like SMF 2.1 is to blame here...


--- Code: --- mysqli_query($connection, 'SET SESSION sql_mode = \'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION\'');
--- End code ---

SMFHacks:
I see must be something new. MySQL 5.7 does have ONLY_FULL_GROUP_BY enabled by default.

I will make the 2.1beta beta fix and do a test on the latest SMF 2.1 from github.
