Namespace[edit]

Question: should this page be moved to the Wikipedia namespace? I see that some pages are in the Help space, such as Help:Starting a new page, Help:Template, etc. but would this be better in the Wikipedia space along with pages such as Wikipedia:Article size, Wikipedia:Redirect, Wikipedia:Categorization, etc? Robert 21:57, 8 October 2005 (UTC)

  • I think that would be a good idea. Courtland 03:47, 17 October 2005 (UTC)
Okay, I moved it. If anyone has a problem with it, let me know. Robert 22:51, 17 October 2005 (UTC)
I see no problems here. Good work! --Siva1979Talk to me 23:30, 31 May 2006 (UTC)
I'm wondering if this actually belongs in mediawiki space (i.e. m:Purge, a page which does not exist) as it appears to be a mediawiki function and not one specific to wikipedia. For instance, see the "How do I purge cached pages?" section of the MediaWiki FAQ. User:Ceyockey (talk to me) 00:02, 1 June 2006 (UTC)

Purge tab[edit]

Can there be a tab for purging the current page on top, alongside "article", "discussion", "edit this page", etc.? Either by default or is there code for placing it in the user's CSS file? --Geopgeop 07:14, 28 June 2006 (UTC)

I found just that. See Wikipedia:WikiProject User scripts/Scripts/Add purge to tabs. See Wikipedia:WikiProject User scripts/Scripts for instructions. Note that you must import the code on the purge source page. Don't copy the purge source or change that page. Will (Talk - contribs) 06:35, 12 December 2006 (UTC)
The above instructions, rather the info on the linked pages, really isn't clear to me. I'm interested in making a tab accessible to all users, even anonymous ones, that when clicked purges the cache for the currently displayed page. What would be the best way to accomplish this? 156.145.28.120 (talk) 19:59, 24 August 2009 (UTC)

Image thumbnail purge instructions confusing[edit]

Could someone please revise/rewrite the instructions for purging images, for example, using a stepwise format (1., 2., 3., ...)? I'm having trouble getting a thumbnail to display, and I'm not sure I'm following the instructions correctly. Robert K S 19:22, 13 November 2006 (UTC)

I'll second that, I just wrote below:
this section has something I don't understand. It reads, "The solution is to request the thumbnail with an unusual URL, say by appending ?1 to the end." Q: how does one request a thumbnail, what does that mean? Pdbailey 00:36, 17 September 2007 (UTC)
Yes, the description is confusing. What should be added where? A few examples definately would make things clearer. Shinobu 17:12, 4 November 2007 (UTC)

How to purge[edit]

The instructions say to add &action=purge to the url. This doesn't work. If you want to purge Main Page, you have to change "/wiki/Main_Page" to "/w/index.php?title=Main_Page&action=purge". Also, it tells you to add {{purge}} to the page. But saving it automatically refreshes the page. You should click "Preview" instead of "Save", then click the purge link, or make a just dummy edit (like adding a space) to the page. --67.121.126.160 02:53, 30 November 2006 (UTC)

If you enter the URL in the form http://en.wikipedia.org/wiki/article then to purge it you add
?action=purge, thus:
http://en.wikipedia.org/wiki/article?action=purge.
Or you can do
http://en.wikipedia.org/w/index.php?title=article&action=purge.

Cache Auto-Purge?[edit]

Is there a way (either Wikimarkup or HTML) to code for a page to purge its cache upon (or ideally before) loading? -RadicalOneContact MeChase My Tail 05:49, 2 February 2010 (UTC)

I was also wondering about this. I frequently update basketball team pages and I have to purge each page after editing the standings to force the standings template to update each time. --Zach Pepsin (talk) 14:29, 15 January 2014 (UTC)

How it works[edit]

"How it works" does not seem to explain why sometimes, and for days after an edit has been made, an old version of the article itself (not a subpage or template) may be displayed, only finally being updated when the cache is purged. It seems that there is more to it (and more things that can go wrong, or at least suffer from latency) than the explanation pretends. (Note that I am not talking about issues with local caching, I'm talking about Wikipedia's own caching.) 86.152.242.168 (talk) 17:51, 13 April 2010 (UTC)

Try both purging the article, and then bypassing your browser cache (Ctrl-F5 in Firefox). Do the purge first. --Timeshifter (talk) 13:56, 16 April 2010 (UTC)
Thanks, but I already know about doing both these things. My point is not to ask for advice on procedures for rectifying the stale page problem, my point is that the "how it works" section does not seem to adequately explain why the problem occurs. 86.146.47.224 (talk) 19:23, 16 April 2010 (UTC).
OK. Hopefully, someone who understands it better than me can clarify that section. --Timeshifter (talk) 23:50, 16 April 2010 (UTC)
You can also purge a page by just clicking on "Edit" at the top of the page, and then just click on "Save". Your edit will not be displayed in the page history, but it will purge the page. See Wikipedia:Purge#Optional way for more information on how to do it that way. Thanks. /HeyMid (contributions) 16:12, 14 August 2010 (UTC)

Why would you want to do this?[edit]

Well, why? There should be an addition in the lead of the project page indicating the purpose of this thing. Your puzzled friend, GeorgeLouis (talk) 17:45, 7 September 2010 (UTC)

I don't understand the purpose of purging either. --Shovan Luessi (talk) 04:22, 6 March 2011 (UTC)

Purge is flaky?[edit]

Is there a reason why purges often don't work? Here are a couple examples...

File:Haakon7.jpg - If you click that link, you are presented with the OLD image. Click that old image and you get the NEW image. No amount of "?action=purge" seems to get the displayed image to update.

File:Hoapili_Kaauwai_and_Kiliwehi.jpg - If you click on this one, you get the NEW image. Click that new image and you get the OLD image.

WTF?

This sort of thing doesn't happen all the time, just sometimes.

Am I doing something wrong or is the Wikimedia software simply squirrely?

JBarta (talk) 23:51, 13 May 2011 (UTC)

I have the same problem here with File:Vectorbundle.svg. Old Thumbnails but if you click them you get the new picture. I tried all sorts of "purge" nothing works. Why??--Svebert (talk) 17:29, 20 November 2011 (UTC)
ok... know everything is fine. Was it just random luck or did the additionally link from here to the picture the magic "purge"??--Svebert (talk) 17:31, 20 November 2011 (UTC)
Seems buggy (not flakey) to me! After making changes to low level documentation templates, only some of the articles including it get purged correctly. Others do not, even after using purge directly. Only clicking edit, then save (with no changes) does the trick. SChalice 18:02, 16 February 2012 (UTC)
The images mentioned, i.e. File:Haakon7.jpg File:Hoapili_Kaauwai_and_Kiliwehi.jpg File:Vectorbundle.svg are all images on commons. You need to go to the commons page before purging. The link to the commons page is in the box below the image, and is shown as "description page there". --Redrose64 (talk) 21:04, 16 February 2012 (UTC)
A day after making the changes, I went to my Special:WantedTemplates and saw deleted templates that my wiki had thought had links to. I kept refreshing that page and witnessed it slowly purging the articles that needed it. Each refresh kept ticking the number down on the deleted templates. SChalice 00:40, 17 February 2012 (UTC)
Two things: (i) Special:WantedTemplates is no longer maintained: at the top it states "The following information is cached, and was last updated 18:25, 15 October 2009. ... Updates for this page are currently disabled. Data here will not presently be refreshed."; (ii) when a template is deleted - or just amended - the pages transcluding that template are not updated immediately, but must take their turn in the job queue. If there have been many template changes, the job queue can take some hours to process a task. It's not a problem with purging. --Redrose64 (talk) 13:08, 17 February 2012 (UTC)

Plain English for Template:Purge[edit]

There is a discussion about revising the language of this template at Template talk:Purge#Edit request: plain language. ~ Ningauble (talk) 19:48, 29 November 2011 (UTC)

When will this be fixed?[edit]

Hi, does anyone know the current status of this bug and when it is likely to be fixed? — Preceding unsigned comment added by 86.176.210.14 (talk) 01:48, 14 January 2012 (UTC)

Wording in "How it wortks"[edit]

Maybe I'm reading it wrong or completely misunderstand the software, but I don't think this section is describing things properly. To my knowledge, any user of Wikipedia gets a parser-cached page if one is available. The difference for registered editors is that the cached page has to match their preferences (like default thumbnail size, etc) or else it gets re-parsed for them (and cached). But if the last editor of the page had the same prefernces as me, I would get the version cached when they looked at the page. This has to be true, because I need to use ?action=purge too, to get a page to display properly - so I'm obviously not getting a re-parsed page every time I view it.

As to the parenthetical "(Logged-in users have a choice...)", the option I see is "Disable browser page caching", is that what is meant? I read that as being about the browser cache on the individual editor's computer (i.e. automatically WP:REFRESH), not anything to do with how MediaWiki does its own caching.

Am I right on these two points? Or wa-a-ay off? Franamax (talk) 00:41, 27 January 2012 (UTC)

Twinkle friendly clock no more?[edit]

It looks like the Twinkle friendly clock no longer exists. If so, should it no longer be mentioned as a means of purging the cache? — Loadmaster (talk) 16:06, 23 May 2012 (UTC)

Automated purge for all pages that are using a particular template?[edit]

Recently a template was vandalized (see this discussion). After fixing it all the pages that used it need to be purged (these pages). Doing each manually is painful. Is there a script that can help with this? - Subh83 (talk | contribs) 16:36, 27 December 2013 (UTC)

The job queue is supposed to. But seven months ago something happened to it, and it's much slower and sometimes misses pages. --Redrose64 (talk) 20:27, 27 December 2013 (UTC)

Trick to purging video?[edit]

The page/thumbnail is updated but when you click on the video (and this is any time not just in this particular file's case), the pop up plays the old video. It does update eventually but over a significant amount of time (so far its been 12 hours for instance). Darkwarriorblake (talk) 11:17, 9 January 2014 (UTC)

Responsible recursive purging?[edit]

What would constitute irresponsible use of the recursive purge? 20 articles? a thousand? fifty thousand? The current verbiage is not only incredibly vague, it offers absolutely no guidance on how one would go about evaluating whether a particular request should or should not be made. VanIsaacWScont 06:17, 18 August 2014 (UTC)

REVISIONTIMESTAMP[edit]

The {{REVISIONTIMESTAMP}} variable shows the time of the last actual edit to the page, for example 20160129232540 which represents 23:25, 29 January 2016 (UTC). I have found that if a WP:NULLEDIT is made, the value returned by {{REVISIONTIMESTAMP}} is the time when the WP:NULLEDIT was performed; but if you subsequently do a WP:PURGE, the value returned by {{REVISIONTIMESTAMP}} is restored to the time of the last actual edit to the page - any intervening NULLEDITs are ignored. --Redrose64 (talk) 10:29, 7 June 2015 (UTC)

Substituting redlinks[edit]

When you use subst: with a non-existent template or page, no expansion occurs. If the template or page has later been created, editing the page with subst: without changing the text will not make a null edit, but instead substitute the created template or page. GeoffreyT2000 (talk) 03:32, 17 October 2015 (UTC)

Which is why all edits should be WP:PREVIEWed - especially those where you added a template or used subst:. --Redrose64 (talk) 07:43, 17 October 2015 (UTC)

Substituting Template:Void[edit]

Adding {{subst:Void}} is treated as a null edit. GeoffreyT2000 (talk) 01:47, 18 December 2015 (UTC)

Yes, because once the <noinclude>...</noinclude> portion is removed, there's nothing left. But having clicked the edit tab in order to add a {{subst:void}} it's far quicker to simply not type that in, and go straight to Save page. --Redrose64 (talk) 08:49, 18 December 2015 (UTC)
