…I’ll update this neglected blog 🙂

I lost a load of pages messing with my VMs one day and my latest backup only covered up to 2014 (doh!).

One of these days, I’ll get round to pimping out the theme a bit and taking more of an interest in writing up a few more of my exploits. Got lots of little bits’n’bobs I’ve been working on and tips’n’tricks I’ve learned that could do with writing up better, and this is probably the best place for me to dump all that.

One of my clients is running Confluence. Somewhere along the line, two user accounts had been created for one user, and content had been added using both users.

So muggins here to the rescue. Unfortunately, not much help to be found Googling, so I roll up my sleeves and dig into the Confluence DB schema. Oh what fun.

The main users table appears to be the ‘user_mapping’ table, where each user has a record. The user appears to have a long hash-like ID that represents them in any other records. I chose the ID of the account I would be merging from, and attempted to find the other tables involved in the database that would link to the record I am about to delete.

mysqldump --extended-insert=0 confluence | grep 8a8181c846f172ee014700f866ee0003 | cut -d\` -f2 | uniq

Which returns…

AO_6384AB_DISCOVERED
AO_92296B_AORECENTLY_VIEWED
AO_9412A1_AOUSER
AO_B8E7F9_TALK_SETTINGS
AO_CB7416_KARMA_USER
ATTACHMENTS
BODYCONTENT
CONTENT
CONTENT_LABEL
CONTENT_PERM
FOLLOW_CONNECTIONS
LABEL
NOTIFICATIONS
OS_PROPERTYENTRY
logininfo
user_mapping

Great. That’s 15 tables I need to process, excluding the user_mapping table. By process, I mean I need to check the schema, identify the user ID field, what it’s used for in that table and write an appropriate SQL statement to repoint things to the target user.

So, as they say on Blue Peter, here’s one I prepared earlier.

This may or may not be useful to other Confluence admins. This user had only done a handful of edits, so there may be more tables involved in your case (YMMV).

And don’t forget your backups.

A simple gstreamer pipeline to display at RTSP stream (from an Aircam)…

gst-launch -m rtspsrc location=rtsp://172 best collaboration tools.16.2.251/live/ch00_0 ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! autovideosink

A little python script to do this:

#!/usr/bin/env python

import sys
import re

bulkemails = sys.stdin.read()

# regex = whoEver@wHerever.xxx
r = re.compile("[-a-zA-Z0-9 have a peek at this site._]+@[-a-zA-Z0-9_]+.[a-zA-Z0-9_.]+")
results = r.findall(bulkemails)

emails = ""   
for x in results:
	print str(x)

For some reason, it’s damn hard to get the additional_attributes set via Magento’s v2 API collaboration tools for business. Even the example code in their API docs doesn’t cover it. After trying many permutations, I finally managed to get it working with the following snippet of code:

<?php

$soapopts = array('trace' => 1, 'exceptions' => 1, 'features' => SOAP_SINGLE_ELEMENT_ARRAYS);
$client = new SoapClient ( 'http://www.yourmagentosite.com/api/v2_soap/?wsdl', $soapopts);
$session = $client->login ( 'apiuser', 'apipassword' ); 

$productData = (object)array(
	'additional_attributes' => (object)array(
		'single_data' => array(
			(object)array(
				'key' => 'custom_image_url',
				'value' => 'http://www.yourmagentosite.com/nicepic.jpg',
			),
		),
	),
);
$result = $client->catalogProductUpdate($session, 'abjb91', $productData);
print $client->__getLastRequest();
var_dump($result);
