Well, the reasoning behind this looks a little bit flawed to me. I can understand the basic idea of a new user right allowing to modify site JS. But:

Vachovec1 added a comment to T188134: Increase usage of noexcerpt class in IPA and pronunciation related templates.

The examples in the second paragraph are not about IPA/pronunciation, these are citation/source related templates. They are all saying something like "dead link" or "source required". Obviously this should be stripped. On cs-wiki these are displayed via the templates which all have a common span class, namely "doplnte-zdroj". But I am not able to find the definition of this class in a local MediaWiki css or js file.

@ovasileva - T182321#3992796 is an example of an edge case or a bug? The preview should probably not accept css definitions designed for the normal article text. The above mentioned gadget may not be the only one that will influence the preview.

that should be fixed in the gadget. The styling introduced by said gadget is very generic. Vachovec1 would you be so kind to flag that to the gadget author(s)?

Well, the gadget definition is here:

MediaWiki:Gadget-HighlightRedirects.css

It's actualy very simple/basic code. So what would you propose?

The en-wiki has something very similar:

MediaWiki:Gadget-DisambiguationLinks.css (author: @kaldari)

I presume that the behaviour would be the same.

I can see a difference between cswiki and enwiki gadget: .mw- (cs), a.mw- (en). Probably the easiest fix to make both disambiguation and redirect gadgets work only on links in articles, not on spans (as @bearND pointed) in previews.

This can be fixed easily and very quickly on cswiki's side, it is up to developers, if they will fix this in previews as well.

Vachovec1 added a comment to T168716: Mobile infobox styles do not work well with multiple column infobox rows.

@ABorbaWMF the problem with the header of this infobox has nothing to do with this task. It's T168861. The infobox header can be inserted two ways: as "title" (caption over the top of the table) or as "above" (text within the uppermost cell of the table). In the mobile view, the first option results in a line of unformatted text as we can see here. The second option works as expected - the result is a formatted (centered, enlarged, custom colored etc.) caption.

This just got more sinister -

Using Firefox on English Wikipedia, I am able to type in the Edit summary box with CodeMirror enabled, but when I click on one of the character insert buttons (provided by the CharInsert gadget, IIRC), as I do with most of my edit summaries to get the "→" character (as in: "somethng" → "something"), it always inserts into the article edit box even when when focus is in the Edit summary box

Also seems somewhat related to T164905: function mw.toolbar.insertTags does not work with CodeMirror in Chrome and IE.

for a few pages, such as the two in the initial report, but some still have
a memory consumption higher than the threshold, unfortunately.

@zhuyifei1999 : I see that this bug blocks solving fallout from T171392 for Commons. The problematic template is "nowikized", but the pages are still broken (from this bug, not from T171392) until cache invalidation is forced? Perhaps Mediawiki-Cache project should be added and contacted. Evidently, the cache invalidation for (rather) all pages with the problematic template is needed, but "normal" ways won't work.

Vachovec1 added a comment to T170039: Pages display Lua error in mw.wikibase.entity.lua.

When I try to purge the page in the previous link through the API (with forcelinkupdate, which has the same effect as a null edit) also results in a Internal Server Error. Tried another year and that gives the same problem. Selected a random cat on my watchlist (https://commons.wikimedia.org/wiki/Category:Psychologists_from_the_Netherlands) and I can purge that one through the API. But I don't know if that error has anything to do with this ticket or that it's a coincidence.

@Mooeypoo : this task is not about MediaWiki:Recentchangestext as a whole, but about interwiki links provided by it. Note that no interwiki links are present in your examples. They should be provided by MediaWiki:Recentchangestext page, they are part of the code (see https://cs.wikipedia.org/w/index.php?title=MediaWiki:Recentchangestext&action=edit). But nothing is displayed. This worked well a few weeks ago.

@Vachovec1: I already answered you about that in T170039#3467750. If a page is reparsed without updating link tables, a transient warning might be cleared while leaving the page in the error category until something does trigger a link table update.

Side note: the Category:Pages with script errors (cs-wiki version) contained a lot of false positives. We found similar false positives in Category:Pages where expansion depth is exceeded and Category:Pages with malformed coordinate tags (cs-wiki versions). Is this another bug, which would be hopefully solved with deployment of the new HHVM-Luasandbox too?

Vachovec1 added a comment to T173089: Watchlisting confirmation dialog interrupts editing.

For the clarity, this bug is not about usual popup window with watchlisting information (which is shown in the previous comment from @Deskana above). It's about dialog which is opened in the new page, and you are asked to confirm your (un)watchlisting choice. The trigger for the "unusual" dialog could be expired token (as hypothesised by Schnark). The problem is no warning if you are in middle of editing when you trigger the dialog.

@Schnark: an expired token (associated with the watchlist) is definitely a possibility as the trigger (see below). But anyway, NO warning is shown, the dialog is launched immediately (no meddling with the preferences).

To disallow page watchlisting in the middle of a page editing is also a possibility. One gets used to it. Perhaps the icon should be hidden in this case so the editors are not confused.

@daniel: I am not sure, but I am inclining to the version where both errors occurs independently. The category is completely unreliable (or the pages are reported with a long delay?). On cs-wiki someone probably just made a purge run through it (no affected pages are shown, not mentioning false positives), but when searching directly for the error massages, I can easily found about 100 pages with the "line 34" error message (almost no false positives) - that is much more then two days ago. About 20 pages with the "line 37" error message (again, almost no false positives). Independently of the type of the error message, the effect on the affected page is the same.

I see that from about Jun 13, there are ongoing problems with WMF ParserCache - T167784, probably as consequence of https://gerrit.wikimedia.org/r/#/c/354504/. Could it be related? A real root cause for bugs like this and T168040? Both bugs seem to be a consequence of some parser cache failure. And the dates sum up (first reports for T168040 are before Jun 20, first reports here are from Jun 23 - at en-wiki).

@Vachovec1: Desynchronization between the displayed version and the category membership is easily explained: not every parse of the page updates the links tables. If you have certain user preferences set, you see the page parsed according to your preferences but that result does not necessarily correspond to the state of the links tables. Further, the web UI action=purge doesn't update the links tables either (which is why null editing is a "stronger" version of purging).

@Vachovec1 it's transcluded on 117893 pages, many have the potential to break (although the exact conditions are still hard to tell). If someone really needs to access the page, they are free to ?uselang=en. I don't see much benefit in removing the templates from the affected pages.

A lot of false positives (all purged), three real cases of this error (one purged /important page/, two remaining : https://cs.wikipedia.org/wiki/Litold_Znojemsk%C3%BD and https://cs.wikipedia.org/wiki/PlayStation_3, if someone is able and willing to catch and post the cache version info here). But I found that there are pages with this error which are NOT displayed inside the category. Examples: https://cs.wikipedia.org/wiki/Svat%C3%A1_Lucie_(osoba), https://cs.wikipedia.org/wiki/B%C3%ADlsko_u_Ho%C5%99ic.
