Arch Linux User Repository

Hello @all,

@kuzalj thanks for the analysis, I have pushed your modifications. For debug Seahub, in ~/domain.tld/conf/gunicorn.conf.py you can change daemon = True by daemon = False and run manualy manualy ~/domain.tld/seafile-server/seahub start.
With this the Python Exception appears.

Regards,
Joffrey

@kuzalj, Well. Now it's clear why all stuff has working on my server without errors.

pacman -Ss python-django-rest-framework
community/python-django-rest-framework 3.12.1-1 [installed: 3.11.1-1]

I've not upgraded for the last few weeks so my one is still on 3.11.1

Thanks for information. I will know what to do after next upgrade :)

@trap000d

I FIXED IT. I went looking at the Github for seahub after noticing the error is related to django-rest-framework. There is a commit that somehow made it right after 7.1.5 requiring djangorestframework==3.11.1 instead of the undefined version before. I started researching, and 3.11.1 is the last version that supports django 1.xx. The version of django-rest-framework in the Arch repo is too new for Joffrey's bundled version of django, which is 1.11.29. Version 1.11.29 is required for Seahub however, as it relies on an old version. I believe I was reading in the commit history that they are updating to 2.xx the next release.

Either way, you need to bundle this older version of the rest-framework much like Jeoffrey did with django-picklefield. I edited the PKGBUILD to grab version 3.11.1 of django-rest-framework in the same way, and re-copied seafile-server, and everything is working again. @Joeffrey, since Arch updated the package, the package you depend on is too new and you will have to bundle rest-framework until the next seafile version updates with django 2.xx

I believe i have python-django installed, because I use it for other packages. But Joffrey's package (look at the PKGBUILD) downloads django-1.11.29.tar.gz and sets it up to be used. So in effect, running seahub makes you use django 1.11.29. This was done on purpose i thought by Jeoffrey because we needed the older version?

@kuzalj, Check your python-django (or python2-django) installation

ImportError: cannot import name 'ProhibitNullCharactersValidator' from 'django.core.validators'

'ProhibitNullCharactersValidator' was implemented in Django 2, so if you still have any instance of Django 1.x around, it might break all things.

@trap000d

Thank you for that!!!! I finally got useful console output.

I am going to start looking into this myself, but this is what I get as an error.

@kuzalj, I afraid I have no more ideas. Here https://forum.seafile.com/t/seahub-wont-start-anymore/9705 and here https://forum.seafile.com/t/where-is-seafile-server-7-ce-for-raspberry-pi/9359/7 they suggested to change "daemon = True" => "daemon = False" (note the letters case!) in gunicorn.conf (now it's gunicorn.conf.py) then seahub on start will redirect all messages to console instead of /dev/null so you might obtain a bit more info.

@trap00d,

I dont use WebDav support, so would I even need seafdav? I don't have a configuration file for it, and it seems like that wouldn't be the thing stopping seahub from starting up correct?

To be sure, I checked, and I forgot I had nginx live streaming RTMP running on that port, so I just switched that port number instead to something else. The port is now open, and I double checked with your command, thank you again :)

Seahub still doesn't startup however, so problem still here :(

@kuzalj, Port 8080 might be in use on your server. On my machine it assigned to seafdav, you can check it either with lsof or netstat:

sudo lsof -i:8080
COMMAND PID    USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
python3 600 seafile    8u  IPv4  32375      0t0  TCP localhost:http-alt (LISTEN)
python3 767 seafile    8u  IPv4  32375      0t0  TCP localhost:http-alt (LISTEN)
python3 769 seafile    8u  IPv4  32375      0t0  TCP localhost:http-alt (LISTEN)
python3 772 seafile    8u  IPv4  32375      0t0  TCP localhost:http-alt (LISTEN)
python3 774 seafile    8u  IPv4  32375      0t0  TCP localhost:http-alt (LISTEN)
python3 776 seafile    8u  IPv4  32375      0t0  TCP localhost:http-alt (LISTEN)


sudo netstat -tulpn | grep 8080
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      600/python3


=== seafdav.conf ===
[WEBDAV]
enabled = true
host = 127.0.0.1
port = 8080
fastcgi = false
share_name = /seafdav

P.S. You only need to install 'python-wsgidav-seafile' for WebDAV support (I need it so have to maintain this package :)
