ScudCloud Version

ScudCloud 1.57
Python 3.5.2
Qt 5.5.1
PyQt 5.5.1
SIP 4.17

Distro and Desktop info

Ubuntu 16.04 64-bit
Unity desktop
Kernel version: 4.4.0-92

Expected behavior

Actual behavior

When launched, Scudcloud hangs with the loading animation, but never loads any data. Cannot find anything relevant in logs: syslog, Xorg.0.log, etc. Not sure where Scudcloud logs activity.

Often, closing the window and restarting Scudcloud a few times fixes it. Today, restarted Scudcloud at least 10 times. Finally everything loaded after trying Edit/reload about 4 times.

Screenshot attached.

The "self help test" succeeds; results pasted below:

Everything seems to have worked. If you're still experiencing problems, tell us about it.

Steps to reproduce

1. Launch Scudcloud, either from the command line ("scudcloud &") or from the dock icon.

Hi @pfogel and thanks for reporting this issue.

I didn't notice this... are you under a slow or intermittent connection?

Anyway, I'll keep an eye on my desktop too to check if I'll watch this behavior.

[pfogel]

My connection is fast and steady; part of a University infrastructure and in a building that used to house a super computer center: >200 Mbps.

I reported this because it has been happening pretty consistently. Every morning when I launch Scudcloud I have to restart it multiple times. This morning it took more than 30 minutes of fussing with it to get it to load data.

Where does it log so that I can check what is going on? Or do I need to launch it in debug mode or something like that?

[raelgc]

You can check the JS console: start in the command line with scudcloud --debug=True &, then after it loads, right click in the message pane and select Inspect.

Maximize the Inspector window and click in the Console tab.

[mtb-xt]

I'm seeing the same issue on Archlinux (amd64 kernel 4.12.3):
Scudcloud 1.61, python 3.6.2, pyqt5 5.9.

When launched with debug, I can see some errors in the console, I've attached them in this gist: https://gist.github.com/mtb-xt/d4efe788cd4200fde0014ab0dfe983c7

I'm on 200 mbit\s symmetrical connection, and yes, restarting several times fixes the issue.
But it started only a few days ago for me.

[skarap]

Seeing the same issue. The error are the same as reported by mtb-xt.
Btw I have 2 teams added.

[raelgc]

@mtb-xt I can see several Slack JS errors. Other platform users complained about them too: https://bugs.webkit.org/show_bug.cgi?id=149551

I have a different webkit version running here (I've installed KDE Neon PPA). I'll open the debug console and check if I can see the same JS errors.

[skelband]

I'm getting this with Linux Mint 18.3.

[raelgc]

Please, can you all post the output of scudcloud --version ?

[skarap]

ScudCloud 1.50
Python 3.5.3
Qt 5.7.1
PyQt 5.7
SIP 4.18.1

for me it also started a couple of days ago, so I don't think the webkit issue has anything to do with this.
Also - sometimes scudcloud is able to properly load, if I load slack and login in the browser.

[mtb-xt]

ScudCloud 1.61
Python 3.6.2
Qt 5.9.1
PyQt 5.9
SIP 4.19.3

[pfogel]

performance much better the last 2 days, but i'm not aware of any changes on my end. opens on the first try and loads reasonably quickly. possible something changed at slack?

[raelgc]

ScudCloud itself has not changed in the last 2 months. All Slack changes. They keep working and improving their JS. Sometimes they introduce a change that breaks our simple client and we need to change. But sometimes are just changes that they see are breaking some platforms, so they revert or fix.

I wish they had a proper API, but probably this will never happen.

[loonies]

I'm also affected. So annoying.

[mtb-xt]

The issue seems to have disappeared for me, weird...

[CommodoreCrunch]

I also get this on Arch, but only on the second of two teams. It doesn't matter if I restart, refresh, or sign out and back in. That second team never loads.

ScudCloud 1.61
Python 3.6.2
Qt 5.9.1
PyQt 5.9
SIP 4.19.3

[raelgc]

Someone still affected by this issue? Today I just pushed a webkit update for those on Ubuntu xenial and zesty.

[skarap]

I've seen this yesterday and today. Exiting and starting scudcloud again got it working.

[raelgc]

@skarap, still an issue for you? There are 2 issues related to this:

• QNetworkReplyImplPrivate::error: Internal problem, this method must only be called once. #546: when connection is lost for some minutes, Qt network libraries in qt5 didn't properly recognize when the connection is available again

• The application blocks after starting without internet connection #271: if program starts without internet connection, and the connection is restored after the loadURL timeout, it'll not start properly.

[skarap]

Haven't seen it for a few days now. Will send an update if it stops working again.
Thanks

[raelgc]

Thank you!

[loonies]

I'm unable to start Scudcloud anymore. Anyone else affected?

[ghostofkendo]

Today, it started happening again to me too.
I'm running Arch Linux.

$ scudcloud --version
ScudCloud 1.63
Python 3.6.2
Qt 5.9.1
WebKit 602.1
PyQt 5.9

[loonies]

Same here. Turned off Scudcloud the last night, unable to start it since this AM :(

[raelgc]

This is back :(

[skelband]

Doing the JS debug console thing, I see a load of errors at the bottom.
Trying to upload a screenshot but I get an error from github :(

[raelgc]

[annulen]

@raelgc Note that you can use official binaries of Qt 5.9 and QtWebKit 5.212-alpha2 - they should work fine in Ubuntu 16.04, and you'll just need to build only pyqt5 and scudcloud.

[hanzei]

@raelgc

$ sudo apt show libqt5webkit5
Package: libqt5webkit5
Version: 1:0.0.0+tp5-3

[maciex]

Is there a patched package for Fedora 26? If anyone finds something let me know.

[jsbillings]

Is there a patched package for Fedora 26? If anyone finds something let me know.

@maciex I've built new versions of qt5-qtwebkit in my scudcloud COPR (which I've only ever used personally to track newer versions of scudcloud than what was built by Fedora, I am in no way an official maintainer). The 'scudcloud' package actually doesn't need to be patched, and I only add one patch to qt5-qtwebkit. I've filed a bug on bugzilla asking the maintainer to include the patch, but I haven't heard anything back yet.

[nonspecialist]

I've built new versions of qt5-qtwebkit in my scudcloud COPR (which I've only ever used personally to track newer versions of scudcloud than what was built by Fedora, I am in no way an official maintainer)

With the understanding that your build is absolutely not supported, I've installed it on Fedora 26 and can confirm that it works -- I have scudcloud again! 🕺

[lainglo]

@jsbillings @nonspecialist I'm not familiar with COPR (I just had a look at it now) - would it be possible to use it to build a docker image? I'll have a closer look at it a bit later

[HalisCz]

COPR is for community RPM's. Also I wouldn't recommend docker for desktop applications. Flatpak is more suited for this use-case, and you can use flathub repository

[raelgc]

If we got able to create 2 flatpaks: 1 for webkit (as dependency) and other for scudcloud, we'll face these issues less often. Now we're facing this problem of several distros using different webkits. I know there is a kde-platform package (for flatpak), but it's 3GB.

[jadenPete]

I'm on Arch Linux, any idea of how I can solve this issue?

[HalisCz]

@raelgc

I know there is a kde-platform package (for flatpak), but it's 3GB.

It doesn't matter, currently I am using Telegram and some other flatpaks, and they are all sharing one kde-platform runtime

[vbelloir]

Hi all,
I've used Scudcloub when I was running Opensuse. Since September I' m back to Ubuntu and use the official desktop app, but I want to use scudcloud again.

I'm running Ubuntu 17.10.
Here is the result off scudcloud -- version

ScudCloud 1.63   
Python 3.6.3  
Qt 5.9.1  
WebKit 538.1  
PyQt 5.7  
SIP 4.18.1

I'm using your ppa : http://ppa.launchpad.net/rael-gc/scudcloud/ubuntu.

libqt5webkit5 is not updated with a update & dist-upgrade, and still in

sudo apt show libqt5webkit5  
Package: libqt5webkit5  
Version: 1:0.0.0+tp5-3

Any help please?

[raelgc]

@vbelloir I've tried to publish the same updated webkit in 17.10, but 17.10 appears to have some dependencies problems/changes related to Qt/webkit and the package refused to built in the PPA.

If someone in 17.10 can help, I'll appreciate it. I'm still in 16.04.

[vbelloir]

@raelgc thanks for your quivk answer.
If I can test something, let me know, but I am not a dev, can't help more.

Thanks for your help!

[Alveel]

I'm now running scudcloud in docker using @jessfraz's docker image. Dockerfile + instructions here.

Found a minor issue in the run command, for me the config dir is ~/.config/scudcloud, not ~/.scudcloud.

I also had to install xorg-xhost and run xhost local:docker (my user is in the docker group).

This might also entice you to run other applications in docker as well.

@HalisCz you mentioned docker isn't well suited for this use-case, what are your arguments for that? If it runs fine 😄

[HalisCz]

@HalisCz you mentioned docker isn't well suited for this use-case, what are your arguments for that? If it runs fine 😄

@Alveel I don'ŧ have any "hard data", but I assumed that Flatpak is more suitable for desktop GUI apps then Docker, based on:

• Flatpak used to be called xdg-app, which is a project dedicated to run sandboxed GUI apps on desktop
• First bunch of stable releases of Docker was not able to run GUI app, which could mean it is not chosen purpose of docker
• Disadvantages of docker for GUI apps are mentioned here: YouTube: Why we need a different container purely for apps - Mark Shuttleworth (Canonical)

I too am experiencing this bug in Fedora 27 (my own RPM of your latest release).

$ scudcloud --version
ScudCloud 1.65
Python 3.6.4
Qt 5.9.2
WebKit 602.1
PyQt 5.9.1
SIP 4.19.5

The --debug=True output is in this gist.

There's a lot of OAUTH related data in the URLs that I had to scrub, so if see something in all caps where you expected a big blob of base64 data, that's what happened, as well as anonymizing my employer since we use Google Auth to federate Slack.

LMK if I can help further.

[raelgc]

@vectorsigma You need to find a way to upgrade the system webkit package.

[jsbillings]

I too am experiencing this bug in Fedora 27 (my own RPM of your latest release).

@vectorsigma: I also needed a qt5-qtwebkit package with this patch to let the latest scudcloud work on Fedora 27. The patched package is also in my scudcloud copr repository. I've filed a bug against the Fedora qt5-qtwebkit to have the patch included, but so far it's been ignored.

[jsbillings]

@vectorsigma It looks like an updated qt5-qtwebkit is currently being rolled out that addresses this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1513091

I just tested it in Fedora 27 with the fedora updates-testing repo enabled, and scudcloud launches without needing my custom qt5-qtwebkit package.

Just to share a bit of investigation: Slack uses react, which relies in use of ProxyObjects. Webkit doesn't work that well with ProxyObjects. React says webkit is not a supported environment:

I log in to 2 teams, and always get this on the topmost one; a ctrl-r fixes it

[jideogunmekan]

Hi installed scudcloud last week and getting the same error

my log file is as attached

[raelgc]

All these changes are caused by Slack improving/changing their product. I'm stopping ScudCloud development, please see #628
