Summary: "Unified diff" not unified (edit_diff)
Product: MediaWiki extensions
Version: any
Platform: All
URL: http://commons.wikimedia.org/wiki/Special:AbuseLog/121
696
OS/Version: All
Status: NEW
Severity: enhancement
Priority: Normal
Component: AbuseFilter
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
The unified diff field in the details of an abuse filter hit are not unified.
It shows all the previous page text with a "-" in front of it, followed by all
the new wikitext (including any and all unchanged lines) with a "+" in front of
it.
This causes false positives in filters looking for patterns in the
"added_lines" field.
As example:
http://commons.wikimedia.org/wiki/Special:AbuseLog/121696
For those not able to view that hit (due to rights):
It triggered filter 74 which has the following one-liner as "Condition"
("{{http://"; in lcase(added_lines))
The diff generated by MediaWIki itself in the edit made is as following:
|Author=[[User:流雨创意工作室|流雨创意工作室]] |Author=[[User:流雨创意工作室|流雨创意工作室]]
|Date=2010-11-12 |Date=2010-11-12
- |Permission={{OTRS pending}}
+ |Permission={{subst:OP}}
|other_versions= |other_versions=
}} }}
So the only thing changed is a template in the Permissions-field.
