Update to CEF 80.0.4

[salvadordf]

Just updated and there are some pages on Facebook that aren't loading correctly in my app, but load correctly in Chrome.

I could get this error on console, any hints ?

Code: Select all

ErrorUtils caught an error:

Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.. [Caught in: React reported an error]

Subsequent errors won't be logged; see https://fburl.com/debugjs. : <a class="_4-h7 _5qtn fbReactComposerAttachmentSelector_SELL" role="tab" aria-selected="true" data-tooltip-delay="500" data-tooltip-display="overflow" data-tooltip-content="Vender algo" data-hover="tooltip" attachmentid="SELL" label="Vender algo" icon="[object Object]" loggingname="sell_tab_selector" href="#" id="js_5"><span class="_4-fs"><i class="_5qto img sp_yHO0idSrpbE sx_5ad02a" alt=""></i><span class="_5qtp">Vender algo</span><span class="_4-h8"></span></span></a>

If I remember correctly, that error message appears when you set GlobalCEFApp.DisableReadingFromCanvas and the web page has issues with that setting.

Thanks for the info about those preferences!

I'll add them to TChromium as soon as I can.

I also detected some issues with the cookies and the latest CEF binaries. Some cookies are deleted automatically in the new version but I still have to investigate more.

I'm experiencing this issue too , the websites don't stay logged after closing the app.

I could reproduce this with the official CEF sample application so I created an issue in the CEF project:
https://bitbucket.org/chromiumembedded/ ... omatically

Yes, everything works now and there are no problems with the CEF79 files either, apparently there was a problem in the component? The previously compiled demo (CEF79) still works with glitches.
But it's good that everything is fixed.

I found this setting, like it is not in CEF4Delphi.

Code: Select all

UpdatePreference(aBrowser, 'profile.default_content_setting_values.cookies', 2);
or
UpdatePreference(aBrowser, 'profile.managed_default_content_settings.cookies', 2);

0 ==> default,
1 ==> Allow,
2 ==> Block.

After activation in DevTools, we will see this remark.

This set-coockie was not stored due to user preferences.

I just uploaded a new CEF4Delphi version with 2 new properties : TChromium.AcceptCookies and TChormium.Block3rdPartyCookies

Thank you again!

hello! I tried new version, but cookies are deleted after I exit my app. I used that "allow cookies" option but it doesnt help. any ideas? Everything worked before, my latest build was on 79 version. Oh and I see it is "allow" by defaut too. So it should work
persistsessioncookies is true as before

this needs to be solved fast, really critical bug

It's an issue in the CEF libraries.

I created an issue in their project giving all the details I could find :
https://bitbucket.org/chromiumembedded/ ... omatically

Register in bitbucket.org and vote for that issue to improve the possibilities that other developer decides to fix it.
