Crash after 2-4 seconds on fedora 27 and 28

[SuspiciousDeer]

Operating System Version: Linux fedora core 27 Popcorn Time Version: Tried on 3.10 stable, build 279 and build 200, same results

Report: Popcorntime used to work. After a system update some days ago it crashes. After updating to fedora 28 still nothing.

Terminal output and general behaviour can be seen here: https://webmshare.com/WB0bM

It does generate a core dump and crash reports.

Same here with fedora 27, it happened after a dnf update. Also I tried downloading the source and running it, but it didn't work

Same here I get the error:

Illegal instruction (core dumped) [4299:4299:0505/101045:ERROR:gl_context_glx.cc(228)] Couldn't make context current with X drawable.

when launching from command line.

Same here. I also tried to build from source but failed.

Just adding to this thread. Exactly the same thing here. After the update for Fedora 28, Popcorntime crashes just a few seconds after opening. It used to work fine. It looks like something related to networking. It doesn't crash if I open it without an internet connection (but what's the point of using it that way? heh).

same here

Confirmed with build 279 as well (https://ci.popcorntime.sh/view/All/job/Popcorn-Time-Desktop/279/)

Adding to the hypothesis of a networking-related bug, this is the first library file listed on the crash backtrace: /opt/popcorn-time/lib/libnw.so

[andreicristianpetcu]

I still have my issue :(

Another one here

Another observation is that the app does not crash when there isn't any internet connection available, so it would seem that the crash comes from something network related in the application.

If the app is started before a network connection is present, it's possible to navigate around the app, but the sections "Movies & Anime" just displays a spinning wheel, while the "Series" section gives the following error message: "The remote shows API failed to respond, please check http://status.popcorntime.sh and try again later".

Just tried this on Fedora 27 with kernel 4.16.7-200.fc27.x86_64

Issue confirmed. After upgrading from fedora 27 to 28 Popcorn stopped working.

I have the same issue, but I've executed the executable that can be found here: https://get.popcorntime.sh/build/Popcorn-Time-0.3.10-Linux-64.tar.xz

I tried to use gdb to analyze the coredump file, to me the issue seems to reside in libnode.so

Could it be some dependencies issues for running nwjs? Someone have tried to run nwjs alone?

[Persei08]

My actual idea is it is related to nwjs on which PT is based. I wonder if some required libraries were updated/removed in fedora.

Things interesting to know will be:

• if nwjs current version can run on fedora (seem to work)
• if nwjs 0.18.6 version can run on fedora (seem to work)
• if custom build nwjs 0.18.6 can run on fedora (seem to work)
  • to test with option "seed update" disabled and more.

edit: added notes after feedback from @EliaGeretto

[EliaGeretto]

@Persei08 I tested both the current version of nwjs and version 0.18.6 on Fedora 27 and both work with the sample HTML-only application presented in the documentation. As for the rest of the tests, I am not that familiar with nwjs or this project, but maybe one of the contributors can replicate the issue building in a Fedora 28 VM.

[Persei08]

@EliaGeretto , thank you. I have updated my previous comment with your feedback.

The custom build of nwjs 0.18.6 used in PT can be found here. If you or someone want to test.

The issue also happen when building under Fedora. @andreicristianpetcu have experimented that in issue #777.

[EliaGeretto]

@Persei08 Again, it seems to work without any issue with the sample HTML-only application I used before. Obviously it does not exercise the framework as extensively as Popcorn Time though. The application can be found here.

[Persei08]

@EliaGeretto , Ok Thank you. I will see for installing a fedora 28 VM but I have to move partitions first

[andreicristianpetcu]

@Persei08 how should I run PT with that build of nwjs?

[Persei08]

ha great. In gulpfile.js, edit downloadurl parameters of nw const (line 63 128), remove this parameter or put 'https://dl.nwjs.io/' instead. This way you will be able to build with untouched nwjs packages and see if results are different.

[andreicristianpetcu]

@Persei08 damn :( crashed again... the line I changed was 128, not 63.

Any other ideas? Is it possible it was still using the old nw? Can I help with any log info?

[Persei08]

Yes it's line 128 :/ .

So, if you have run gulp clean and run all the usual commands: npm install bower install gulp build gulp run

?

In the output you see don't have seen it downloading the new nwjs package? Or it said something like 'using cache' ?

Drumrolls

AAAAnd IT WORKED!!!!

[Persei08]

You have the nwjs complete changelog here maybe try with nwjs version blundled with node 7, 8, etc...

[andreicristianpetcu]

I use the latest LTS Node v8.11.1 with ndenv.

[Persei08]

Ha great it works. Can you try with the 0.25.2 and 0.25.3 the changelog for 0.25.3 let me think something interesting was fixed here.

[andreicristianpetcu]

@Persei08 both 0.25.2 and 0.25.3 failed but they showed a popup with some profile error which I did not see before. I sent a PR with the update to the latest version and I have 5 more minutes of battery on my laptop :D

[Persei08]

The PR will not help. The standard nwjs do not support lot of codecs. That's why pt and butter use custom builds of nwjs.

[Persei08]

@andreicristianpetcu , the profile error message is related to downgrade of nwjs. I think you need to delete the app folder saved in this path (look for "Popcorn-Time" instead of "\<name-in-manifest>").

[Persei08]

I cannot install fedora 28 vm in virtualbox. It run the live mode but when I choose to install it, it just freeze... tried several times on laptop and desktop :/ . Will retry later

[Kidlike]

@Persei08 So how do we create a new build of nwjs the pt/butter way ? You could try a Vagrant flavor of fedora, they usually work.

[Persei08]

@Kidlike I don't know exactly, all I know is there are some explanation here: https://github.com/butterproject/butter-desktop/issues/647 and in the nwjs doc.

I'm not familiar with vagrant, I assume i have to configure things to have a desktop environment? But I have finally installed fedora28 xfce version and got the same error (Illegal instruction), the VM is just slooow :/ .

I'll do more tests and come back I have some news.

[Kidlike]

Hm... I just realized, couldn't we just use @andreicristianpetcu 's workaround and then just stream to VLC instead of playing in the embedded player ? :)

[Persei08]

I think it should work

[Kidlike]

So, it works... But I was getting this error when doing gulp build:

Downloading: https://get.popcorntime.sh/repo/nw/v0.30.5/nwjs-sdk-v0.30.5-linux-x64.tar.gz

Unable to download NWjs. 

Which is probably related to what @Persei08 was saying that this won't help.

But then I noticed from @andreicristianpetcu 's post that his download URL is different. I don't know how is that possible. Anyway, I did this step manually (download and extract that file inside the cache folder). Now everything works (video playback only through VLC streaming).

Any ideas where that URL comes from ?

[Persei08]

see my comment here: https://github.com/popcorn-official/popcorn-desktop/issues/776#issuecomment-390802230

[Persei08]

At the moment i have tested with all higher versions (0.18.6 -> 0.20.1) of nwjs custom builds available on pt repo and I always get the 'Popcorn-Time exited with code 0'.

Now I will test with nwjs official builds to see from which version number the error disappear

[andreicristianpetcu]

@Persei08 do you want to do some dev work on Fedora 28 or just testing the fix? I'm pretty sure I can find somebody runing Fedora 28 that actually has this issue :D

@Kidlike I changed the URL from line 128

// nw-builder configuration
const nw = new nwBuilder({
    files: [],
    buildDir: releasesDir,
    zip: false,
    macIcns: './src/app/images/butter.icns',
    version: nwVersion,
    flavor: nwFlavor,
    downloadUrl: 'https://dl.nwjs.io/',
    platforms: parsePlatforms()
}).on('log', console.log);

[Persei08]

I'm just testing, I just want to find the lowest version number which work and check the nwjs changelog.

[Persei08]

ok, it work since nwjs version 0.30.1 which doesn't help me to understand :/

So as a workaround you can build it with nwjs 0.30.5 from official repo and then swap the libffmpeg.so with the one provided here: https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases . libffmpeg.so must be swapped in ./popcorn-desktop/cache/0.30.5-sdk/<platform>/lib for dev purpose (gulp run) and in ./popcorn-desktop/build/Popcorn-Time/<platform>/lib/ if you want to generate redistribuable packages (gulp dist).

It will support a bit less codecs than PT custom build, but for the dozen movies I have tested it worked great, for episodes sometimes (1/4) there was no sound.

It seem to generate other little issues, but PT still work (movies, episodes, subtitles, torrent collection).

[choonming]

I would like to add that while building it with nwjs 0.30.5 from https://dl.nwjs.io and switching the libffmpeg.so worked for me, the streaming to the TV via chromecast does not work for the subtitles. There will be an error stating that subtitles could not be converted while the movie plays normally.

[burmanh]

Unfortunately I've found the most satisfactory workaround to this beeing the use of the windows build in a 64-bit wine prefix on Fedora 28, almost everything works as intended except streaming tv-series, strangely enough...the loading tends to be somewhat slower due to the extra software layer though, but if you can live with that it's a good enough solution for the moment.. @EduardKuun has a good point, I described the "best way" for the 3.10 build, 3.09 works perfectly and so does popcorn-time community edition (uses the same api as 3.09) on fedora 28.

[EduardKuun]

I've been trying to find a solution to this problem for weeks. If you are adamant on using version 0.3.10 I can't help. Follow this https://get.popcorntime.sh/repo/build/ link. Download version 0.3.9 and extract the tar.xz file. Navigate to the extracted directory and run the ./Popcorn-Time command. Should work fine.

[llaine]

+1 not being able to run on Fedora 27.

I'm getting some [1] 4566 illegal hardware instruction (core dumped) ./Popcorn-Time

[christianbueno1]

thanks @EduardKuun 0.3.9 works on fedora 28 workstation

[christianbueno1]

hello pals after run PCT 0.3.9 , I downloaded PCT 0.3.10 and ran it Here the output

[harvey@localhost Popcorn-Time-0.3.10-Linux-64]$ ./Popcorn-Time 
./Popcorn-Time: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

And PCT 0.3.10 doesn't run on fedora 28 workstation

[red-I2P]

Same issue here. I hope we can fix this soon, a very serious bug.
