textsecure crashes when connecting to server

[MrSqueakySquirrel]

What is expected: TextSecure is started and connects with server.
What happens instead:
When TextSecure is started and a connection to the internet is available the application crashes when trying to connect to the server.

Here are the latest log entries. The websocket.Dialerror appears multiple times in todays logs, but not in previous logs.

�[34mINFO�[0m[2017/04/11 20:29:32] websocket.Dial wss://textsecure-service.whispersystems.org:443/v1/websocket/?login=%2B49{PHONE_NUMBER}&password={PASSWORD}: dial tcp: lookup textsecure-service.whispersystems.org: Temporary failure in name resolution
�[34mINFO�[0m[0000] Setup completed
�[37mDEBU�[0m[2017/04/11 20:29:46] PUT /v1/directory/tokens 200

When TextSecure is started and no connection to the internet is available the application shows a warning and remains responsive, (expected behaviour)

Since today (~ 8 hours ago), the app also crashes for me, however, I do receive new messages but the app intermediately quits after launch.

No errors get logged when there is a network connection:

INFO[0000] Setup completed                              
DEBU[2017/04/11 22:37:21] PUT /v1/directory/tokens 200
                

Following the advice in this report by launching the app in flight mode, does work: the app remains running.
But then the following line (of course) shows up in the log:

INFO[0000] Setup completed                              
INFO[2017/04/11 22:38:34] websocket.Dial wss://textsecure-service.whispersystems.org:443/v1/websocket/?login=%2B{PHONE_NUMBER}&password={PASSWORD}: dial tcp: lookup textsecure-service.whispersystems.org: Temporary failure in name resolution

sorry I don't know off the top of my head what it could be, I haven't worked on the project in over a year and no longer have a working phone to test with.

Lots of sad news these days for ubuntuphone users :-(

It seems that the application receives an empty message from the server an tries to extract the mac from a non-existing offset which causes a "panic: runtime error: slice bounds out of range". I could fix (?) this in the console version by adding:

if len(msg) == 0 {
    return nil
}

to the handleReceivedMessage (textsecure.go:460) function.

As far as I can see, there is nothing wrong with just ignoring those empty messages.

Are you going to release a fixed version for ubuntu phone?

[janimo]

Eventually I'll probably do so. I'll have to check my long unused build setup and ask others to test the click before uploading to the store.

[luxpir]

It'd be highly appreciated if you found time to do so. Just another +1.

[K14D]

I really appreciate your effort. Let me know if I can help.

[janimo]

I built a new click, could any of you test it, I don't have a phone anymore.
BTW it's just running ./build.sh rel from the source dir, I'd be curious if that works for others as well.
It pulls a few docker images and needs to have a local GOPATH with textsecure and textsecure-qml cloned.

In a short test your click runs fine on my Aquaris E4.5.

I tried to build the click myself, but the package github.com/ubuntu-core/snappy/helpers could not be found. So the build failed.

[janimo]

It must have moved or gone away since I last built, I still have it in my local $GOPATH.
I'll need to find its new location, thanks for the report.

I am very happy to read that you are finally work on the project.
On Pro5 runs fine too.

Thanks for all Jani (your Signal client library for Go works perfect on Sailfish OS, under Whisperfish).

[timothymctim]

Any plans to upload to the store? Otherwise, how do I manually install? Just a pkcon install-local textsecure.jani_0.3.12_armhf.click without needing to uninstall the current app first?

Yes. At least for me, this worked fine.
