Mostly empty page on most page loads

[jrfnl]

As of today, I'm seeing mostly empty pages on initial page load:

This is accompanied by the following JS error:

12:32:57.307 TypeError: parent is null

Doing a reload/F5 allows for the page to display, but having to do that every other click gets old fast.

I can replicate on recent (UXP-based) Serpent 52.9.0; it's quite random, though, but, as OP mentioned, quite annoying 😞 ...

It does happen also with latest palefill, which was recommended as a substitute for this, no longer maintained, extension...

Since the TypeError message is generated from the following GH script:

https://github.githubassets.com/assets/chunk-vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-539e3d6a1773.js

... I tried blocking it with uBlock Origin (legacy),

"My Filters" tab, add:

! github.com
||github.githubassets.com/assets/chunk-vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-539e3d6a1773.js$script,important

... and I haven't witnessed any breakage thus far... YMMV, of course 😉 . This isn't a solution per se, just a "dirty" workaround...

[Vangelis66]

... Today, GH have started serving another manuelpuyol_turbo script that breaks things for me (latest Serpent 52.9.0 32-bit),

https://github.githubassets.com/assets/vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-b12e520649c0.js

I've blocked that one too in uBlock Origin (legacy), so far so good:

! github.com
||github.githubassets.com/assets/chunk-vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-be659c79aff6.js$script,domain=github.com,important
||github.githubassets.com/assets/vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-b12e520649c0.js$script,domain=github.com,important

01/07/2022 EDIT: It looks like that second script is no more being served:

https://github.githubassets.com/assets/vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-b12e520649c0.js => Not Found 

so the blocking rule initially posted in my previous comment should be just enough for now... 😉

[jrfnl]

Looks like the Palefill extension doesn't solve this issue so far and I don't have the uBlock origin extension.

might make sense to contact that dude and tell him to fix his shit

Looks like they flicked a switch that enables (eg, environment-e9a18cc2906a.js:1:1909) v=n(y=>y?.tagName==="TURBO-FRAME", ...) instead of v=n(y=>(y?y.tagName:null)==="TURBO-FRAME", ...) or v=n(y=>(y && y.tagName)==="TURBO-FRAME").

... Well, he's on GitHub,

https://github.com/manuelpuyol

currently "Building UI @github" and committing code to https://github.com/github/browser-support (among others...)

@dirkf Is your log from SeaMonkey 2.53? Looks like they broke browsers without native Optional Chaining Operator ("?.") support :angry: ...

Addendum: In a Chromium 78 fork (360EEv12), at least one of the GH scripts now also requires native browser support for the Nullish Coalescing Operator ("??"):

Uncaught SyntaxError: Unexpected token '?'  https://github.githubassets.com/assets/vendors-node_modules_lit-html_lit-html_js-50b1c3ae31f7.js:49

[dirkf]

2.53.12. Forthcoming 2.53.13 has ?. but may break other extensions in interesting ways.

[rofl0r]

ok, i'll use my magical powers to summon him @manuelpuyol @manuelpuyol @manuelpuyol

[dirkf]

Unfortunately it's not Manuel's source that's the problem, it's how GH sends the code, as well as their apparent complete lack of anything that might pass for version control or release management, which is really beyond ironic.

github-wc-polyfill-1.2.19.1-unofficial

generally solves the problem. sometimes "discussions" are displayed strangely (it helps to reload the page)

[garoto]

Just updated to latest Palemoon (v31.1.0) so just I could use this shit site again and vangelis66 uBlock directive made it finally usable. Thanks dude!

And while at it, holy shit, it's all getting to the point of no return faster and faster. Meanwhile, child of the moon can't commit a single C++ line of code to address any of these major websites breakages.

It was all a scam from the beggining. At this pace, SerenityOS libweb will be more compliant with shitty modern webtech standards faster then one can write "lol, just use Chrome dude".

[wyatt8740]

@roytam1 Thanks for your work.

However, this does not appear to fix the problem in Seamonkey 2.53.7, though. Unsure why that is, since WebComponents is still largely an enigma to me.

I don't know if this will be useful to you, but... here's some console information from loading the github.com home page:

Palefill also does not work.

[roytam1]

However, this does not appear to fix the problem in Seamonkey 2.53.7,

please update your seamonkey to 2.53.13.

[wyatt8740]

@roytam1 Good idea. I was actually just doing that since I realized after commenting how out of date 2.53.7 was.

Compiling it now. Will be back in a few hours if all goes well.

[Vangelis66]

@wyatt8740

Your report is just a duplicate of dirkf's comment above 😉 ; last Monday, Microsoft (current owners of GitHub) started serving newer scripts that contained the Optional Chaining (?.) and Nullish Coalescing (??) operators; both of them are supported by Chromium >=80, Firefox >=74 and Pale Moon == 31.1.0 (also, by most-up-to-date UXP forks), but NOT SeaMonkey <=2.53.12 😢 ...

The XPI kindly attached by @roytam1 is targeting platforms already supporting natively those two operators 😉 ... BTW:

SyntaxError: expected expression, got '.'

signals that your browser/platform doesn't support "?.", while

`SyntaxError: expected expression, got '?'

signals it doesn't support "??"...

palefill also does not work.

See open issue https://github.com/martok/palefill/issues/29

EDIT: Newer comments showed up as I was typing this... If you can, yes, update to SM 2.53.13+...

[wyatt8740]

@Vangelis66 @roytam1 thank you; finished my seamonkey 2.53.13b1 build and it is working. Sorry for the bother.

... Optional Chaining (?.) and Nullish Coalescing (??) operators ... NOT [supported by] SeaMonkey <=2.53.12 cry ...

??: 2.53.12+ ?.: 2.53.13+

There are some exotic cases of ?. that, reading between the lines of the release notes, haven't yet been sorted (in .13).

[Vangelis66]

Well, I can't run any SM Windows build in this old x86 laptop past v2.49.5 (FxESR 52.9.1 based?), so I can't test myself... In retrospect, I should've been more careful when reading the log dirkf posted above, apparently on SM v2.53.12, in that only missing support for "?." is reported there - unlike the log by wyatt8740 (in SM v2.53.7 at the time), where both operators were missing...

??: 2.53.12+ ?.: 2.53.13+

Thanks :smile: , I got the "real" :wink: story already elsewhere - but you, too, follow that thread...

EDIT: In my defence, I did write:

both of them are supported by Chromium >=80, ... , but NOT SeaMonkey <=2.53.12

which seems to be a true statement, because 2.53.12 ONLY supports ONE of them :stuck_out_tongue_winking_eye: ...

[AroKol78]

(by the way - broken https://github.community/)

on Serpent52.9.0 once I raised the version (68-->91 useragent) it seems to work (by the way, "webmasters" 👎 is artificially inflating the requirements)

I had this problem with Waterfox Classic too.

The "github-wc-polyfill-1.2.19.3-unofficial" seems fix it... Maybe you can update the official extension?
