Can you submit the iOS debug log too?

@xanderdunn What if you turn off disappearing messages?

[xanderdunn]

@liliakai It looks like turning off disappearing messages made the messages appear only once on desktop. Turning it back on, it eventually came back.

I didn't try more than 3 test messages, so not very scientific.

[liliakai]

Thanks. That's enough to hint that this is related to disappearing messages on the desktop side. Most likely a race between saving the message initially and then immediately updating it to start the countdown timer.

[Realiserad]

Same as #1038?

[liliakai]

Not the same.

This also happens in messages sent from Signal on Android.

[deutrino]

And, it happens with me using Signal Android when I have Signal Desktop online - not just offline. Also, often one of the duplicates has a single "sent" checkmark, not the duplicate return receipt checkmark. I do wonder if #1038 is somehow related.

I'll try to do some rigorous testing in the next few days, this is happening almost constantly with me.

[Trolldemorted]

@gordon-morehouse very unlikely.

#1038 is about hiding group messages that were duplicated because of network failures, you are experiencing something else (or your messages fail once every time).

[deutrino]

Okay, I got this to happen in a short span of time as shown in the screenshot from Desktop, and here are debug logs on both platforms. Relevant phone number ends in 005.

Do we know enough about this bug to remove the "iOS" and "Mac" bits from the title?

I experience the same thing, as does someone else I talked with. Messages sent on Signal mobile from me appear duplicated when I use Signal desktop, though the recipient only sees them once.

I spent some time investigating this today, and I have a couple questions and a couple requests. First a couple questions for those of you experiencing this:

• How many devices do you have on the receiving side, and how many on the sending side?
• Does anyone experience this in a conversation without disappearing messages turned on?

Second, if you're willing, it would really help to know if these are truly different messages or a re-render problem. To determine if the application thinks about these as totally different messages, you can check these two places:

• DOM: If you're running a debug version, you can right-click and 'Inspect' on the message. Check to see if the id of the <li> tag is the same for the duplicate messages. You can do the same thing if you're running the production release by going to chrome://extensions then clicking 'index.html' just right of 'Inspect Views.' Doing things this way, you'll need to manually dig down through the web page to find the messages.
• In-memory: It would also help to see if there are duplicate messages in the the conversation's message list. To check that, you'll have to open the background page. Right-click and choose 'Inspect Background Page' or click background.htm (on chrome://extensions) if using the production build. Then enter window.ConversationController.get('+<phone number for the target conversation>'); into the console. You can then click into its messageCollection property, then its models property. The newest messages will be the last in the collection, with high index numbers. The data for each message is in its attributes property.

Thanks!

I'm experiencing the same problem.
I use Signal on Android and when I exchange messages with someone who uses Signal on IOS and who also has the Desktop Application on a Mac OS, my messages (both sent and received) duplicate when I switch to my own Signal Desktop App, which is also on Mac OS Sierra (as a Chrome app, of course).

In the past I can confirm that some messages duplicated, but it happened quite rarely and I don't remember exactly the context. Sometimes it happened for several messages in a row, but then it all went back to normal.

For the second task I found it a little bit difficult to understand what you mean exactly. (I've downloaded the Signal Desktop app from here https://chrome.google.com/webstore/detail/signal-private-messenger/bikioccmkafdpakkkcpdbppfkghcmihk).
If I go to the extensions page in Chrome and then I right-click on Signal and click "Inspect", I get the html code on the whole Chrome extensions page (so it doesn't matter exactly where I click 'inspect', it's the same code). I'm not sure where to go to from there and how I could inspect the messages themselves.

[scottnonnenberg]

@lethargosapatheia Thanks for jumping in and trying to gather that additional information for us. If you're not familiar with using the Chrome Desktop Tools, then it will be a little more challenging for you. The idea is to see where the duplication occurs - if you're inspecting the right file (index.html) you'll be able to highlight different tags and you'll see them show up on the page. When you find the items that represent the duplicated messages, we want to know if the ids are the same.

I see the same issue. I have disappearing messages enabled with someone who uses Signal Android (and desktop as well) while I have Signal iOS + Signal Desktop on macOS. Only my (the iOS/macOS) user's messages get duplicated on desktop.

[jschneier]

Also the spinning bar at the top is constantly there which might just be a disappearing messages feature but looks like a syncing thing and appears buggy to me, there are already indicators that disappearing messages are enabled.

When I experience this, I only have my phone and desktop linked. I had zero duplicated messages, then I turned on expiring messages from my android device. All messages sent from android were shown twice on the desktop. After sending 3 messages, I shut off disappearing messages on the android device and no more duplicate messages appearing on the desktop from android.

[scottnonnenberg]

Signal Desktop 0.42.1, released to the Chrome Web Store today, has message de-duplication and a number of bug-fixes around disappearing messages. Please re-open this if you run into this behavior again.
