Currently WebKitDownload::suggest-filename is emitted when WebKit wants to know the location at which to download a file. The application is expected to display a file chooser using gtk_dialog_run(), then return the result to WebKit using webkit_download_set_destination(). In GTK 4, gtk_dialog_run() no longer exists. The only way to accomplish this is to handle it manually, e.g. using your own GMainLoop to iterate the default main context. Either way, it's not very safe. We should find a way to improve this for the GTK 4 API. One possibility would be to add a webkit_download_start_download() function to allow the application to asynchronously handle things and then indicate to WebKit that it is ready. That might not be needed, though: alternatively, we could make it mandatory to call webkit_download_set_destination(), and just not start downloading until that has been called.
> Either way, it's not very safe. Well apparently this is not just a theoretical concern. I noticed today when investigating bug #245625 that Ephy is seeing new downloads start when running its nested main loop to handle the current download. For example, there are actually four main loops in this backtrace, three nested ones plus the toplevel. This is why gtk_dialog_run() is so scary and no longer exits: Thread 1 "epiphany" hit Breakpoint 1, webkitWebViewDecidePolicy (decision=0x5555573e0f90,

So I've been thinking about this. The most elegant way to handle this is to say that if you return TRUE for WebKitDownload::decide-destination but without calling webkit_download_set_destination(), then this indicates that you will eventually call webkit_download_set_destination() later on, and the download should not start until having done so. This is also pretty easy to implement because internally everything is already designed to be asynchronous. I think we could even get away with changing this in the original API version, because well-behaved applications should surely return FALSE if they're not going to set a destination. It would be pretty weird to return TRUE and block other handlers yet not set a destination. I also did a Debian codesearch and verified that there are very few applications using this API at all. But we could alternatively limit this behavior to new API version only. Opinions?

Sounds good to me, and I think it's safe to do it in current api too.
(In reply to Carlos Garcia Campos from comment #3) > Sounds good to me, and I think it's safe to do it in current api too. I also noticed that the current API takes a URI that it converts to a filesystem path. But GtkFileDialog returns a path, so the application has to convert to a URI for no reason and then WebKit converts back to a path. So we should just take a path instead. And that change certainly cannot be backwards-compatible, so needs to be limited to new API version only. We could still make the async behavior change available to the old API version if desired, but since there is some small compatibility risk and it's no longer possible for me to avoid version-specific differences, I'll arbitrarily choose not to.

Eh, actually it's two separate changes really... easier to make the async change everywhere, and the URI -> path change only for new API.
