Header Tabs sometime fails to load

19
Jongfeli (talkcontribs)

Ever since we upgraded to MW1.35 it sometimes happens that opening a page that uses multiple headers fails to load properly.

Everything is on the page and the tabs are also on top but all the page content is shown below the first header. The tabs do not work.

When you go back one page and click on the link again or use F5 the page loads normally and after that it seems to keep working until time X has passed.

I get the fault Exception in module-execute in module ext.headertabs (see screenshot) and I tried to figure out what is going on but I am not sure where to look first.

Can someone please push me in the right direction :-)

Nice work getting that screenshot ready for public viewing! Are you using the latest version of Header Tabs? Also, I would recommend adding "?debug=true" (or "&debug=true") to the URL, then reloading until the error happens - the error message in the console may be more helpful.

Jongfeli (talkcontribs)

Well it is not up to me, it is our company wiki :-)

I tried lots of times with the links and adding ?debug=true but it does not want to fail.

Then it happened when using &action=purge. On some pages we use a link with &action=purge to force a Sematic update.

The below code was in de Console, maybe this helps. I will try tomorrow with the debug option and dig some more.

Okay - it's not surprising that this error message does not show up in debug mode. It sounds like a timing problem (some JS is getting called before it is defined), and the timing is quite different in debug mode. What version of Header Tabs are you running?

Jongfeli (talkcontribs)

I updated the all extensions early December 2020, Header Tabs has version: 2.0 (adfd26a)

Wiki config:

Product Version
MediaWiki 1.35.0
PHP 7.3.23 (cgi-fcgi)
MariaDB 10.4.11-MariaDB
ICU 64.2
Elasticsearch 6.5.4
Yaron Koren (talkcontribs)

Alright. My guess is that the Header Tabs lack of display is a symptom of a problem with some other extension or skin... that error message, "items[i].toggle is not a function", doesn't seem to relate to anything in the Header Tabs code. Actually, I have no idea what that is coming from. If you create a wiki page with just tabs, or just tabs and text, do the tabs ever fail to load?

Jongfeli (talkcontribs)

Okay maybe this helps, I can reproduce the fault on our TestWiki by purging a page with ?action=purge.

Then I disabled all extensions one at a time until I found out that when disabling the Page Forms extension the page loads normally and I can not reproduce the fault anymore.

I have done this several times, disabling and enabling Page Forms and the fault can only be reproduced when Page Forms and Headertabs are both enabled.

I tried to do the same on the SMW Sandbox Page but I only managed to reproduce this a couple of times. See screenshots below.

I just tried it again by pressing purge page on https://sandbox.semantic-mediawiki.org/wiki/Utilisateur:Jongfeli and it failed again.

It seems that somehow after "X" time a purge page can results in this fault.

Jongfeli (talkcontribs)

Okay, today I updated both Headertabs and Page Forms to Master and suddenly it does not matter if Page Forms is enabled or not, the fault always appears.

To make a long story short, Page Forms has "nothing" to do with it (but I am not sure about this).

When you use Page Forms Master and Headertabs release 1_35 it works just fine.

The page now reports This page is using the deprecated ResourceLoader module "jquery.ui". Please use OOUI instead. but it works just fine.

I assume the move in Headertabs from jquery.ui to OOUI is somehow causing this problem after a page has been purged with &action=purge.

Maybe it has something to do with the fact that a &action=purge is now done with POST that needs to be confirmed.

I did find the items[i].toggle in the below js script.

For now the 1_35 version of Headertabs fixes the problem with an added bonus, we have our familiar blue tabs back :-)

    OO.ui.StackLayout.prototype.updateHiddenState = function (items, selectedItem) {
      var i,
      len;
      if (!this.continuous) {
        for (i = 0, len = items.length; i < len; i++) {
          if (!selectedItem || selectedItem !== items[i]) {
            items[i].toggle(false);
            items[i].$element.attr('aria-hidden', 'true');
          }
        }
        if (selectedItem) {
          selectedItem.toggle(true);
          selectedItem.$element.removeAttr('aria-hidden');
        }
      }
    };

Thank you for investigating this - including finding that part of the JavaScript code. All of what you're saying makes sense, but I can't reproduce the problem, with MW 1.35 and the latest Header Tabs code. Does this happen for you with every page that uses Header Tabs - even a very simple one?

Jongfeli (talkcontribs)

No it does not happen on every page, only on pages with multiple tabs (6 to 12) which contain SMW queries.

They take relatively long to load +/- 5 to 10 seconds. Like the example on the SMW sandbox.

See: https://sandbox.semantic-mediawiki.org/wiki/Utilisateur:Jongfeli

On the SMW sandbox site it only happens sometimes, not every time you purge a page. So there is definitely something going on.

I will test some more in the SMW sandbox, maybe we can get it to fail all the time.

Yaron Koren (talkcontribs)

I doubt that you can ever get some page to fail all the time, since this sounds like a timing-related issue. I wonder, though, if you can figure out what the simplest page is that will sometimes fail. Are SMW queries always required, for example?

Jongfeli (talkcontribs)

I do not know if SMW queries are required, I do not think so. like you said it has probably something to do with timing.

Today I tried to figure out what the difference is between pages that work and pages that don't.

I thought I found it when I noticed there where UseCDNCache: "false" codes in the cookie request when it worked and not when it failed.

Maybe it has something to do with it but I am not sure, it was introduced in MW-1.34 see: Manual:$wgUseCdn

The only thing that really helped was disabling the HTTP cache in the Firefox debug mode, then it always loads correctly (but takes forever).

This would suggest there is sometimes something wrong with caching or cookies.

Revansx (talkcontribs)

@Jongfeli - Where did you land on this? I am experiencing it too.

Jongfeli (talkcontribs)

Hello @Revansx. We reverted back to an older version of Header Tabs with the old style tabs not using OOUI.

But also this older version does not work correctly all the time and sometimes only loads the first tab but it does not break the page like the more recent versions and as shown in the screenshot above. This is on MW 1.35.6 I am not sure which version this is, it says 1.3 but that is probably not correct.

I did not investigate any further but the problem is probably still there when using master.

Are you using SMW as well?

Revansx (talkcontribs)

Hi @Jongfeli, thanks for responding. Sounds like we're in the same boat. Yes, I use SMW as well. The HeaderTabs mainatiners don't seem to be able to reproduce this problem and so it has been suggested that this issue may only manifest when HeaderTabs is used with some other extension (maybe SMW, but we can't actually say which until we can reliably re-produce the problem) .. That said it seems clear that the problem has not been solved.

When it does glitch, it doesn't seem to produce any errors or diagnostic info, so my my new strategy is to seek help from the HeaderTab developers for help in adding some debugging tools in the extension. I'll provide an update here if I am able to make any progress on this problem. Please do likewise. Cheers!

Jongfeli (talkcontribs)

Unfortunately the SMW sandbox site is still down. I was able to reproduce it there to.

For MW 1.34.x + HeaderTabs 1.3 + SMW 3.2.3, we were finally able to solve the HeaderTabs issue where the header tabs don't always load. To do so we had modified: /opt/htdocs/mediawiki/extensions/HeaderTabs/HeaderTabs.hooks.php from:

     85                 $resourceLoader->register( [
     86                         "ext.headertabs" => [
     87                                 'localBasePath' => $htDir,
     88                                 'remoteExtPath' => 'HeaderTabs',
     89                                 "scripts" => "skins/ext.headertabs.core.js",
     90                                 "dependencies" => [
     91                                         $jquiTabsModule
     92                                 ]
     93                         ]
     94                 ] );

to

     85                 $resourceLoader->register( [
     86                         "ext.headertabs" => [
     87                                 'localBasePath' => $htDir,
     88                                 'remoteExtPath' => 'HeaderTabs',
     89                                 "scripts" => "skins/ext.headertabs.core.js",
     90                                 "dependencies" => [
     91                                         $jquiTabsModule,
     92                                         "ext.smw.tooltips",
     93                                         "ext.smw.style"
     94                                 ]
     95                         ]
     96                 ] );

specifically we added the SMW resources "ext.smw.tooltips" and "ext.smw.style" as dependencies for Headertabs and that seems to have solved the issue. (fingers crossed)

Hide Level 1 headings in TOC

13
Krabina (talkcontribs)

Usually, Level 1 headings (marked with =) are not used in regular wiki pages. HeaderTabs uses them to define headers. The problem now is that the regular TOC in mediawiki pages also includes the level 1 headings (that already are used and therefore visible on the page in headertabs) are displayes in the TOC again.

Therefore I would need some ability of telling mediawiki NOT to include level 1 headings in the TOC.

As this is only a problem with headertabs it would be great to have a config option...

2.238.45.117 (talkcontribs)

This is my solution.

  1. If you are NOT an expert on mediawiki/semantic read the TOC and SECTIONS related help pages. You will not find at the time I am writing the solution for your problem, but for sure (like in my case) you will end up with a better understanding of it :)
  2. I ended up debugging the code and here the solution.

Considering that the best practice is not to use single "=" for sections this might be taken in consideration as change in the core mediawiki code.. (anyone reading up there?!?)


The solution consists in changing includes/parser/Parser.php.

I left the logic for TOC creation unaltered, otherwise you will end up having problem with the header tabs excentions rendering.

The goal is to declare the Header Tab section within a proper header defined with double "=" and HIDE in the TOC the section declared with single "=".

This last part might be changed in order to show the tabs with an appropriare TOC level, but in this in my opinion/experience is useless because

  1. the header tab section is rendered as unique block
  2. the TOC links are not able to point to the appropriate headed tab.


So..


NOTES:

This change will be applied to every level 1 header defined in your WIKI!!

USAGE:

  1. Declare your section header as == MY SECTION ==
  2. Write within your section your header tab content ( = tab1 = bla bla bla = tab2 = bla2 bla2 bla2 ... <headertabs/>
  3. Add in your page __TOC__ or {{TOC}} (if you are using a template for TOC)

PATCH:

edit your_wiki_path/includes/parser/Parser.php and apply the following changes in the function formatHeadings:

This is again an issue with recent versions of MediaWiki and HeaderTabs.

Kghbln (talkcontribs)

I had hoped that the new version 2.1 fixes the issue, however it does not. I am on MW 1.35.x

Yaron Koren (talkcontribs)

It seems strange to follow up now on an issue that was first reported nine years ago, but: is the issue that the tabs appear in the TOC, or that they appear more important than everything else? I think this is part of why I ignored this issue before: because it seem to me that tabs should appear in the TOC, since they're part of the page structure. However, I admit that it's strange right now if you have normal section headers below all the tabs, because then you end up with a TOC that looks like:

1. Tab 1
2. Tab 2
2.1 Some tab sub-header
3. Tab 3
3.1 Overview
3.2 See also
3.3 References

Everything in the main page looks like it belongs to Tab 3, but it doesn't. What if the structure were fixed, so it instead looked like:

1. Tab 1
2. Tab 2
2.1 Some tab sub-header
3. Tab 3
4 Overview
5 See also
6 References

Would that be good enough? Or would it still be better to get rid of the tabs entirely in the TOC?

Kghbln (talkcontribs)

For quite some years the tabs were not shown and this was fine. Usually you do not use = to create headings within text but start with ==. The latter and lower level headings should be shown. For me the suggestion does not work.

@Krabina: What about you?

Yaron Koren (talkcontribs)

@Kghbln - thanks for the response. Can you explain why you think tabs should not be included in the TOC? After all, they're a part of the page structure...

Kghbln (talkcontribs)

Predominantly I create tabs to have a tabbed infobox. The tabs of the infobox should therefore not show up in the since they are not part of the regular content structure. Same with forms (had to add NOTOC to every form after the extension changed its behaviour). Probably I am misusing this extension.

Replacing second level headers with first level headers appears to be a wrong solution for the right reason.

Yaron Koren (talkcontribs)

Okay, that's helpful. I wouldn't say it's the wrong solution, just not the right solution for your case.

Krabina (talkcontribs)

I agree with Karsten. Also in my case, the TOC shows the structure of the main text as it should (usually level 1 headings are not used anyway). And HeaderTabs are showing tabs for various infoboxes. They should never be part of the regular TOC. Of course, different usecases are possible, but once you are using HeaderTabs it seems to me that they will almost any time not part of the rest of the page structure.

Yaron Koren (talkcontribs)

I don't think I understood most of that, but it's good to know that you don't want tab names in your TOC.

Krabina (talkcontribs)

I just realized that in the current version of HT there seems to be a configruation option for this. However, for me this does not work. If I put $wgHeaderTabsNoTabsInTOC = true; in LocalSeettings.php, nothing changes, if I put <notabtoc/> in the page, the tabs are not shown in the tabs, but no other headings are shown. After some testing I realized that this only works, if the tabs are below the content which heading should be in the TOC.

If I put first level headings and <headertabs /> BEFORE the other content, this does not work. This is unfortunate, because most of the times I use HeaderTabs for templates, where the template content is usually on the top of the page followed by the rest of the content.

Kghbln (talkcontribs)

I can confirm that the new configuration does not work.

images no longer usable as link text in #switchtablink

Revansx (talkcontribs)

I just upgraded Header Tabs to v2.2 (master) and overall its great, but I did notice the we lost the ability to use images as the link text in the #switchtablink parser function. The older versions allowed for it. Was this capability dropped by design or was that an undocumented feature that got lost unintentionally?

Thanks!

Yaron Koren (talkcontribs)

It's the latter.

I edited the 'timeless' stylesheet to fit better in a Bootstrap site (with Chameleon for Mediawiki). How can I make it a proper style recognized by the extension? I tried adding it as a choice from the LocalSettings paremeter for style but I can't figure out how bridge the 'ext.headertabs.bootstrap' value and the right stylesheet.

Sorry about that - this was a (slight) bug introduced about a year ago. I just checked in a fix for it.

Kghbln (talkcontribs)

Affirmative, master works fine. A tag will be great if possible.

Sorry to came back to this issue, but I'm on mediawiki 1.37.1 and right now, during the semantic-mediawiki rebuild, and I can see the same error.

I checked out from git repo the latest code and changed to branch REL1_37.

You should use the master code, not the REL1_37 branch.

HeaderTabs always fail after migration to 1.35

Urarku (talkcontribs)

I migrated Mediawiki to following versions:

MW: 1.35.2

SMW: 3.2.3

PageForms: 5.2.1

Skin Pivot: 2.3.0

PHP: 7.4.21

HeaderTabs: 1.3


It shows only the first Tab and the layout is screwed up. I checked the other posts in here but I think the problem is another one. Well, I am a newbie on SMW.

I get 2 errors in the javascript console:

Error: Unknown module: jquery.ui.tabs

...


Uncaught ReferenceError: wgNamespaceNumber is not defined

...

Does anyone have a clue where the problem could be. My intention was first that the problem could be the skin but also other skins show the same result.

HeaderTabs fail to render image in tab

Krabina (talkcontribs)

in previous versions of HeaderTabs (before 2.0), this worked

= [[Image:Task.png|16px|link=]] Tasks =

in the current version in MW 1.35, the images are not displayed, but the img-tag is shown instead.

<pdf> embed fails to load document on all but first tab

Summary by Zed4242

Resolved by updating PdfEmbed Extension

Zed4242 (talkcontribs)

I use the PDFEmbed extension. The pdf viewer is displayed and the document loads under the default tab. The pdf viewer is displayed but the document fails to load under all other tabs. When the markup is configured to display the second page of the document (e.g., <pdf page=2>File:filename.pfd</pdf>), the pdf viewer is still blank showing page 1/1 until one of the viewer resize buttons is clicked. This forces the viewer to load and display the document. Again, the viewer appears and correctly loads pdf documents only under the first tab. All other tabs display a blank viewer until clicking a button on the viewer (e.g., resize), which then causes the document to load and display properly.

It would appear that the markup is fully executed only for the default header tab page. Is there a way to force complete execution of markup content under all header tabs on the wiki page?

Return to "Header Tabs" page.
