uBlock-user commented 5 years ago

So you will be discarding the filter as invalid ?

gwarser commented 5 years ago

WTH? AdGuard converts this filter to redirect=noopjs! And also have problem with CORS.

uBlock-user commented 5 years ago

Eh! That's not what their KB says.

gorhill commented 5 years ago

discarding the filter as invalid

Of course not -- I wouldn't have opened an issue just for this trivial fix. It will be converted to an empty file -- zero bytes. I had to modify the redirect engine to accommodate the fact that empty can apply to any type of requests, while uBO requires a type for a redirect rule.

To be clear, the list I pasted above was taken from NanoAdBlocker, it rejects filters with empty option.

gorhill commented 5 years ago

And also have problem with CORS.

That's a Firefox issue, extensions should be exempt of CORS as dictated by the server. I don't know if there is an opened issue about this on bugzilla.

liamengland1 commented 5 years ago

I think it's a chrome issue too.

gorhill commented 5 years ago

I fixed the issue locally and it works fine with Chromium.

gwarser commented 5 years ago

an opened issue about this on bugzilla.

I see few, maybe this: https://bugzilla.mozilla.org/show_bug.cgi?id=1419459

uBlock-user commented 5 years ago

I had to modify the redirect engine to accommodate the fact that empty can apply to any type of requests, while uBO requires a type for a redirect rule.

Interesting, so $redirect will be required with $empty or will be independent ?

gorhill commented 5 years ago

That's not what their KB says.

I suspect the empty option works as expected with their standalone product -- while we need to rely on redirection with an implementation meant for extensions.

uBlock-user commented 5 years ago

Well it doesn't stop the incessant barrage of blocked network requests from appearing as it was expected of $empty

test url -- https://www.quora.com/In-Japanese-what-is-the-meaning-of-ka

||log.quora.com^$empty,important

Status in network pane still remains blocked:other instead of returning 200 OK and the barrage continues in the logger

works as expected with their standalone product

@ameshkov is that the case with adguard extension ?

Nevermind, it's the same with Adguard's extension too, it doesn't follow the KB documentation and doesn't as work as expected.

ameshkov commented 5 years ago

Hi all,

Yeah, it works as expected with the standalone products indeed, but in the browser extensions, there's no alternative to implementing it as a redirect to data:base64.

We are actually thinking about deprecating this in favor of $redirect in the future updates. $empty -> $redirect=noopjs conversion is enough for most of the cases so it will be kept until the filter lists are cleaned up.

The ETA is about 2-3 months.

gorhill commented 5 years ago

thinking about deprecating [empty]

I think empty would still be a useful shorthand for redirect=noop[something] -- I am sure filter list maintainers like to have a less verbose way for common cases.

ameshkov commented 5 years ago

@gorhill well, it's up to you then. If you decide to support it, we won't remove it.

Talking about shorthands, $mp4 is another candidate.

liamengland1 commented 5 years ago

Access to XMLHttpRequest at 'data:text/plain;base64,DQo=' (redirected from 'https://play.google.com/log?format=json&hasfast=true') from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

What to do?

uBlock-user commented 5 years ago

That's a browser's blocking notification as you're running into CORS, you will have to set Access-Control-Allow-Origin header by yourself to overide that.

maximou4391 commented 4 years ago

Hello @gorhill, don't know if it's really related but I'm trying to understand why one of our script is return a 307 when Ublock is activated wheread the other indicates only "blocked" image

Is this because the old one is in a way "known" by Ublock?

Thanks a lot in advance,

Maxime.
