Time filed: 14:24, Saturday, May 27, 2017 (UTC)

Automatic, Supervised, or Manual: automatic

Programming language(s): AWB

Source code available: AWB

Function overview: Remove UTM parameters (Google analytics) from external links and references (i.e. resurrect Theo's Little Bot task #23)

Links to relevant discussions (where appropriate): Wikipedia:Bot requests/Archive 55#Remove Google Analytics tracking from external links

Edit period(s): Once a month

Estimated number of pages affected: 16000 in the initial run, and maybe 200 a month after that? Theo's task ran in batches of 500, which also works, but I couldn't then give a timeframe.

Exclusion compliant (Yes/No): Yes

Already has a bot flag (Yes/No): Yes

Function details: Straight-forward find-and-remove. Regex:

• \??(?:&?utm_[^=]*?=[^&\s\]\|]*)+(?=]|\s|\|)|(?<=\?)(?:&?utm_[^=]*?=[^&\s\]\|]*)+& (test cases)
• \??(?:&?utm_[^=\s]*?=[^&\s\]\|]*?)+(?=<|}|]|\s|\|)|(?<=\?)(?:&?utm_[^=\s]*?=[^&\s\]\|]*)+&|(?<=&)(?:&?utm_[^=\s]*?=[^&\s\]\|]*)+& (tests)

As near as I can tell, I've managed to cover all of the edge cases which were of concern in the original BRFA. The blue section covers the case where ?utm_ is followed by an & not followed by another utm_ (e.g. ?utm_example=1234&para=value). The red hits everything else (i.e. where the utm_ term(s) are only at the end of the URL). Green is when utm falls in between two other codes

Discussion[edit]

• As a note, unlike the original bot run this will not be checking to see if the URLs are still valid. AWB doesn't do that. Primefac (talk) 14:24, 27 May 2017 (UTC)[reply]

Approved for trial (50 edits). Please provide a link to the relevant contributions and/or diffs when the trial is complete. Please post results here when done. — xaosflux ^Talk 14:27, 27 May 2017 (UTC)[reply]

Trial complete.. Edits. Note that there were three errors (1, 2, and 3), which I undid and corrected (1, 2, and 3) with new regex, which I've amended above to reflect the changes. Primefac (talk) 15:30, 27 May 2017 (UTC)[reply]

In addition to the UTM parameters, there's also "?cmpid", and probably others. DS (talk) 16:14, 1 June 2017 (UTC)[reply]

An easy addition, just replace utm_ with cmpid in the regex. Primefac (talk) 18:37, 1 June 2017 (UTC)[reply]

 Approved. Task approved. — xaosflux ^Talk 03:44, 6 June 2017 (UTC)[reply]

• Amended (00:29, 7 August 2017 (UTC)) to include ?mbid parameter cleanup as well "speedily approved" in lieu of another task as this is low volume. — xaosflux ^Talk 00:29, 7 August 2017 (UTC)[reply]
