Notes:	"<ref\|</ref" split for clarity Appears to get more and better hits on referenced info now too. Apparently, previous version wasn't working properly. --Mgm Switched on. - It Is Me Here Tagging instead of disallowing, there are plenty of good reasons to remove references. -- Mgm Oh, is this for all references? Wasn't there one regarding removing a {{Reflist}} template? - It Is Me Here That one (filter 79) was a test, and it doesn't appear to be working properly. It hasn't caught anything for at least 24 hours. - Mgm removed private flag, unnecessary -- Zzuuzz Updated format that should also catch named references and avoid the old reference grouping tag. --Mgm Filter 79 now working properly, removing line that specifies reflist. Working on better regex to avoid <references/> being hit with this one --Mgm Changing to edit_delta <= -1000 from >= -1000; seems like this was the intent. >= and <= comparisons are based on actual value, not absolute value. Correct me if this was the intent. Also, we are getting some false positives on this, see http://en.wikipedia.org/w/index.php?title=Interstate_5_in_Washington&diff=279452062&oldid=278504317 - Hersfold >= is correct. It is supposed to exclude large removals from being evaluated since they're covered by blanking filters. It was an error in the regex. Instead of allowing for <ref name="whatever">, the regex allowed choosing between <ref> and <ref name>, the last of which obviously didn't work. -- Mgm added note in filter to avoid confusion --Mgm Altered regex to treat refs as whole blocks, to avoid situation where a duplicate ref is changed to a named ref (<ref>Blah</ref> --> <ref name=foo/>). Now won't catch users removing one end of a ref though. Might have ec'd with cmt above, but can't tell in this wierd system :D --HM Okay... I THINK this is finally a correct regex that: 1) grabs <ref> ... </ref> as entire blocks 2) grabs <ref name="foo"/> 3) ignores <references/> 4) allows newline breaks between <ref> and </ref> tags. 5) grabs only consecutive <ref>, </ref> pairs (as opposed to jumping from the first <ref> to the last </ref>). -DF Restored original version, added exclusions for naming references and removing closing tags of named references. --Mgm Added comments for clarity --Mgm Too many false positives, setting to log only. --Conti From Coppertwig: A more exact count might be obtained by defining a ref-opening as either "<ref>" or "<ref name" and a ref-closing as either "</ref>" or "ref name ... />". (With the named reference, the same tag will sometimes count as both an opening and a closing.) The code might look something like this (assuming rcount expects regular expressions): /* count of removed ref-openings exceeds count of added ref-openings, or count of removed ref-closings exceeds count of added ref-closings; named refs with slashes count as both openings and closings. / & (rcount("(<ref>\|<ref\sname)",removed_lines) > rcount("(<ref>\|<ref\sname)",added_lines) \| rcount("(</ref>\|<ref\sname[^>/]/>)",removed_lines) > rcount("(</ref>\|<ref\sname[^>/]*/>)",added_lines) Adjusted delta to -3000 due to a sock removing references that has been missed due to the total removed content. Ref [[User:Ryulong/Sandbox#Ref_removing_vandal]] - Shirik 24 Jan I replaced \sname with \s(name\|group). - Ruslik Something 'wrong' here .. it catches also '<ref></ref>' (i.e., empty tags, as included in the article creation wizard). They should be excluded. Disable. Most of the hits are false positives. -Sole Soul Mark as deleted. - KoH Simplify (can deal with HTML comments and Wikipedia links if this seems otherwise useful) RF 2015-05-03 Added <ref></ref> since it's easy and cheap. RF 2015-06-04 Added item to ignore if only conversion between <ref> and </ref> - now should probably be re-factored. RF 20150915 Added code to pragmatically exclude most single line comment deletions. RF 20160201 readd tag "references removed" since reenabled - Cen 22-10-2016
