Summary: When multiple "warn" filters are triggered, edit is
prevented
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: Normal
Component: AbuseFilter
AssignedTo: [email protected]
ReportedBy: [email protected]

Given a set of 3 filters:
#1: article_namespace == 0 & "orange" in lcase(added_lines)
#2: article_namespace == 0 & "red" in lcase(added_lines)
#3: article_namespace == 0 & "green" in lcase(added_lines)
where all 3 are set to give warning (but NOT prevented), edits that trigger
combinations of these filters prevent the edit entirely. For example:
Edit session 1:
-------------------------------
1. Add line containing "GREEN"
2. Click Save page: Warning for #3 displays
3. Click Save page again: Edit goes through (correct behavior)
Edit session 2:
-------------------------------
1. Add line containing "GREEN and RED"
2. Click Save page: Warning for #2 displays
3. Click Save page again: Warning for #2 displays
4. Click Save page again: Warning for #2 displays
...etc. The edit is prevented entirely, stuck in a loop.
5. Click Cancel (abandon edit)
Edit session 3:
-------------------------------
1. Add line containing "GREEN, RED, and ORANGE"
2. Click Save page: Warning messages for #1 and #3 display
3. Click Save page again: Warning message for #2 displays
4. Click Save page again: Warning messages for #1 and #3 display
5. Click Save page again: Warning message for #2 displays
...etc. The edit is prevented entirely, stuck in a loop.
6. Click Cancel (abandon edit)
