• 5 years, 8 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Also applied the local patch in config/beid/eidreader.js on weleup site, and sent them email with explanations.
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : I made a local patch of the eidreader.js for welcht and sent them an email with explications. The solution seems satisfying.
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Also focus() doesn't seem to work. One improvement is that when I give a name to the popup window, and when the user leaves this window open, then Firefox won't switch to it any more for subsequent calls. IOW the eidreader popup remains out of the way. But the first time is still disturbing because ...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : My next idea is to call [url developer.mozilla.org/en-US/docs/Web/API/Window/focus window.focus()] in order to switch back to the Lino window after opening the popup, and letting the popup remain open.
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Also I didn't yet find a way to undo my "allow this for all popups". So I cannot really continue to test with my Firefox because now the problem has disappeared (for me).
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : We tried with saying popup.blur() instead of popup.close() but that seems to have the same effect. We also tried with a loop while (popup.event) {setTimeout(()=>console.log("waiting", popup.event),1000)}; but nope: seems that the [url developer.mozilla.org/en-US/docs/Web/API/Window event property] i...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : A new observation: Firefox fails to call eidreader because Lino.beid_read_card_processor() closes the popup window immediately after opening it. When I don't call popup.close(), it works but the popup window becomes activated, disturbing the end user.
  Lino.beid_read_card_processor() = function() {  ...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : I forgot to say that, in order to reproduce, you must also temporarily disable the "eidreader simulation":     go avanti1 ; nano settings/demo.py ; adda "#" in front of the line that says "yield ('beid', 'simulate_eidreader_path', self.project_dir.child('simulate_eidreader'))".

• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Seems that custom URL protocol handlers do still work in newer Firefox versions. To verify this,: go avanti1, runserver, log in as robin. Click on [read eid card]. Open JS console. It says "Gonna open beid://127.0.0.1:8000/eid/5b578a24-fe00-44f2-8264-33cf59a18f3f". Type "beid://127.0.0.1:8000/eid/5x...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : I opened the follow-up ticket #3932 (which needs to be done before it makes sense to publish a new windows zip file).
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Hannes, one part of this will be for you because it requires a Windows machine. At your convenience you can start to try it already now: [url eidreader.lino-framework.org/build.html] (and you will have to create a new zip file when the new eidreader version is ready. This won't be before tomorrow).
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Yes, this idea seems to work. I am almost finished with eidreader version 2, which will work according to this new idea.
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : New idea: the eidreader daemon is actually not an internet server. It would rather just poll every second whether there is a card in the card reader. And when a card is found, send this data immediately to the Lino server. Every client machine would get a unique id (given in its local ini file). Whe...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : But we don't want the eidreader client machines to become public web servers. So actually we won't need a http server. It is rather the eidreader client machin that should contact the Lino server, saying "Here I am, ready to answer your requests".
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : OTOH xml-rpx is maybe overkill and obsolete: [url en.wikipedia.org/wiki/XML-RPC#Criticism].
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : [url docs.python.org/3/library/xmlrpc.html xmlrpc] seems good for this purpose. It is built-in with Python.
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Which protocol should the eidreader daemon use? The most basic would be socket ([url www.thoughtco.com/building-a-simple-web-server-2813571 see this example]), but my feeling says that socket is too basic. Should it be a http server? Or xmlrpc? Or soap?
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : I am afraid that a browser extension won't help either. What we need is a "Lino middleware", i.e. eidreader would become a daemon that is to run on the client machine. The eidreader daemon would accept incoming requests from a configurable address (the Lino server). The "read eId card" button in Lin...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : I found [url developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Your_first_WebExtension this tutorial] about how to write a browser extension. But I am not yet sure whether a browser extension is what we need.
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : This is interesting to read: [url stackoverflow.com/questions/15807038/architectures-to-access-smart-card-from-a-generic-browser-or-how-to-bridge-the]
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : [url medium.com/swlh/custom-protocol-handling-how-to-8ac41ff651eb Here is an article on medium.com] which describes exactly how we use eidreader. But I am very afraid that this is now obsolete. The article is actiually wrong. It ignores the fact that their trick works only with Firefox. And you cann...
• 5 years, 9 months ago by Luc Saffre about #3927 (Firefox stopped to run custom URL protocol handler) : Thanks for the research, Hannes! While this is good as a quick workaround, we now need to find a new method, either for Firefox or for Chrome. So next questions: are custom url protocol handlers really deprecated? Or are there just new methods for confuring them? And if they are deprecated: what oth...
