Bug or what: randomly adding "®exp_filter" into fields edit
Sometimes PetScan adds ®exp_filter into text fields after I hit the "Do it!" button. Those can be found in random fields, like in Linked from or Site links text fields, sometimes in multiple fields and other times just in one field. Any idea what's causing this odd behaviour? Everytime this happens, I'll have to reload a fresh PetScan page to make PetScan work properly because those "®exp_filter"'s break the search. 87.95.206.253 (talk) 17:31, 20 January 2021 (UTC)
- I've seen
®exp_filterappear in the "Link to a pre-filled form for the query you just ran" URLs, causing them to appear in the form when the external link is followed. Certes (talk) 17:40, 20 January 2021 (UTC) - I have the same problem. It is annoying. How can I urge this problem to be solved? --Herzi Pinki (talk) 10:09, 6 October 2022 (UTC)
- PetScan accepts a URL parameter called
regexp_filter. "Link to a pre-filled form..." inserts®exp_filter=valueinto the URL it generates. (value is usually blank.) This works perfectly when the link is clicked. However, such links are often pasted into wikitext or HTML. Some browsers interpret the string "®" as an HTML entity for the registered trademark symbol, even when not followed by a semicolon, so&foo=bar®exp_filter=becomes&foo=bar®exp_filter=, appending the unwanted text to the preceding parameter and usually causing it to make an unwanted appearance in one of the input boxes.Could we change the parameter name to something that doesn't begin with reg? Of course, regexp_filter= should also be accepted for backwards compatibility, but if a replacement parameter name not beginning with reg can be offered in "Link to a pre-filled form" then the problem should be solved.

I have replaced 'regexp_filter' with 'rxp_filter', which should prevent the issue. 'regexp_filter' is still supported for backwards compatibility. --Magnus Manske (talk) 10:55, 22 December 2023 (UTC)
No result for source categories edit
Hi, I'm new to Petscan, just tried using it this evening and I got the following error: "No result for source categories".
This error happened with one of the example queries as well: https://petscan.wmflabs.org/?psid=552
Any ideas what I've done wrong? audiodude (talk) 01:25, 16 July 2023 (UTC)
Petscan displays blank page, unusable edit
https://petscan.wmflabs.org/ just displays a blank page. Taking a peek at the HTML, I see this likely culprit: <body style="display:none">. Reported on Discord, affects at least 2 people. –Novem Linguae (talk) 00:03, 26 September 2023 (UTC)
- I think it's probably unrelated to that CSS, as that line seems to have been there since the tool was created (initial commit).
- However, in the browser-console I see ORES is mentioned, which makes me wonder if phab:T347344 is involved? I've filed a separate task at phab:T347367 (as it's a different error-message) in case it is related. Quiddity (talk) 00:52, 26 September 2023 (UTC)
- It affects me too, and has been thus for a few days now. I didn't think to examine the CSS; I just assumed its server was down. Certes (talk) 10:03, 26 September 2023 (UTC)
- As Quiddity mentions, display:none has been in the repo forever, so is probably normal. JavaScript probably changes that to display:block when it is ready to show the app. The cause of the current blanking is probably ORES-related errors messing up the JavaScript before it reaches the code that shows the app. phab:T347344 is fixed or will be fixed shortly, but there is also phab:T347317 and phab:T347367. These are all ORES-related and are all probably what is breaking PetScan, so all of them probably need to be fixed. Looks like the machine learning team is working on everything except maybe phab:T347317, which may require a code change to PetScan (@Magnus Manske) –Novem Linguae (talk) 16:08, 26 September 2023 (UTC)
- Just reported at User talk:Evad37/rater.js#Missing ORES predication that ORES for Rater is now working. Thought to share here. PETSCAN remains a blank page. Regards, JoeNMLC (talk) 20:38, 26 September 2023 (UTC)

- Good news: PetScan actually works, as long as you go into the browser's object inspector and remove the display:none property manually before using both the query entry screen and the results. Certes (talk) 21:00, 26 September 2023 (UTC)
- All fixed now. Yaay! -MPGuy2824 (talk) 03:04, 28 September 2023 (UTC)

"No result for source categories" edit
When using PetScan, I will intermittently get the error No result for source categories
. There doesn't seem to be anything I can do to control this (at least, that I'm aware of) - sometimes a query will work, and sometimes it won't. I just wanted to check if this was a known/reported issue. (pinging Magnus Manske)
All the best, —a smart kitten[meow] 12:52, 10 January 2024 (UTC)
- A similar problem was reported above. Certes (talk) 13:49, 10 January 2024 (UTC)
- Are you following an old link to a pre-filled PetScan query? A bug, now fixed, put the spurious text "®exp_filter" into a random(?) field on one of the tabs. Blanking that field may solve the problem. Certes (talk) 13:53, 10 January 2024 (UTC)
- @Certes: I'm not, no - this is happening on newly-created queries. Best, —a smart kitten[meow] 13:54, 10 January 2024 (UTC)
- @Certes and meow: Here are some "clues" that seem to make PetScan work better without failing off. 1. At top Tab ↹ forward thru fields to Categories, usually Depth 0 (zero). 2. At Categories, hand-type the cat. as copy/paste seems to often not work. SOmetimes replace those spaces with "underscore" (_). 3. Then "Do it!". 4. If it runs Ok, optional, go back and make Output changes (plain text, sorted, etc) and run again. Bottom-line, while "buggy" maybe these work-arounds can help. Good luck, JoeNMLC (talk) 00:28, 11 January 2024 (UTC)
- When copy-pasting within Wikipedia, I sometimes get unwanted invisible characters such as a zero-width space on my clipboard. I'm not sure where they come from – possibly search results. If typing rather than copy-pasting works, this may not be a PetScan problem. If the text is still on the clipboard, pasting it to somewhere like http://qaz.wtf/u/show.cgi might be instructive. Certes (talk) 09:50, 11 January 2024 (UTC)
- @Certes and meow: More: - Another clue, whenever I launch PetScan without the / after the .org it always runs Ok. Tested on 3 completely different (new) categories with good results. Cheers! JoeNMLC (talk) 01:54, 12 January 2024 (UTC)
- That's weird. Could your browser be auto-filling a field with unhelpful text, perhaps thinking PetScan wants a line of your address or other irrelevant information? You could examine the "Link to a pre-filled form for the query you just ran" and see if it contains any unexpected filters that would limit the search unhelpfully. Certes (talk) 11:21, 12 January 2024 (UTC)
- @Certes - Here's that URL as I'm totally clueless of what to look for. https://petscan.wmflabs.org/?before=&source_combination=&links_to_all=&format=html&manual_list_wiki=&minlinks=&search_max_results=500&cb_labels_any_l=1&categories=Orphaned_articles_from_January_2024&manual_list=&cb_labels_yes_l=1&edits%5Bflagged%5D=both&labels_no=&since_rev0=&smaller=&templates_yes=&output_limit=&project=wikipedia&language=en&show_soft_redirects=both&templates_no=&wpiu=any&edits%5Banons%5D=both&links_to_no=&ores_prediction=any&cb_labels_no_l=1&langs_labels_no=&active_tab=tab_categories&ns%5B0%5D=1&show_disambiguation_pages=both&sitelinks_no=&search_wiki=&langs_labels_any=&sparql=&larger=&langs_labels_yes=&ores_type=any&referrer_url=&edits%5Bbots%5D=both&output_compatability=catscan&interface_language=en&ores_prob_to= It's a plain PetScan, depth-0, cat-Orphaned_articles_from_January_2024 (copy/pasted). So hope this helps. JoeNMLC (talk) 15:51, 12 January 2024 (UTC)
- Nothing there looks suspicious. That URL also produced "No result" for me. I also tried typing "Orphaned articles from January 2024" into a blank PetScan form and still got "No result". Same for 2023, so it's not using an out-of-date cache. Then I messed about with a few things randomly and it started working ... so I went back and tried your version again, without my "improvements", and it works too (718 results). It seems to be an intermittent bug, which is often the hardest sort to fix. Certes (talk) 16:05, 12 January 2024 (UTC)

PetScan currently down edit
Just leaving a notice here that PetScan currently seems to be down, displaying the error This web service cannot be reached. Please contact a maintainer of this project
. This has been reported in the GitHub repo. Best, —a smart kitten[meow] 19:40, 26 January 2024 (UTC)
- Greetings @A smart kitten - Thank you for reporting. I use PetScan almost daily & it's frustrating without. I had searched for where to report without any luck. Do you know of any alternate tool like PetScan? (Category filter, etc.) Regards, JoeNMLC (talk) 16:05, 27 January 2024 (UTC)
- @JoeNMLC: I don’t personally know of any, unfortunately (expect for potentially crafting database queries by hand using Quarry). I’m therefore hoping that this is just a temporary issue :) Best, —a smart kitten[meow] 16:31, 27 January 2024 (UTC)

PetScan timeouts edit
Once a month, I try to run a simple PetScan query- categories=List-Class articles, depth=3, namespace=Talk. The idea that I want a count of all talk pages in a "List" category. This usually takes several dozen tries at minimum to actually return results; this month I'm getting nothing but "Io(Io(Custom { kind: UnexpectedEof, error: "connection closed" }))"
as the response. I'm guessing that this is because it returns around 300,000 results, but I don't know. The thing is, I only need the count, not the page details, so is there a better way to run the query that will actually finish? --PresN 15:21, 1 February 2024 (UTC)
PetScan not working edit
When trying to make any request, I get instead the following error: "Reqwest(reqwest::Error { kind: Request, url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("en.wikipedia.org")), port: None, path: "/w/api.php", query: Some("meta=siteinfo&action=query&format=json&siprop=general%7Cnamespaces%7Cnamespacealiases%7Clibraries%7Cextensions%7Cstatistics"), fragment: None }, source: hyper::Error(Io, Os { code: 104, kind: ConnectionReset, message: "Connection reset by peer" }) })".
