compatibility with raspberry Debian Buster

[sasagr]

I tried to build it in the raspberry pi4 and got the following message during pulling dbpolitepol...

no matching manifest for linux/arm/v7 in the manifest list entries

did u plan to add compatibility to raspberry architecture?

[sasagr]

I managed to install it on my raspberry pi 4 but not with the docker, since arm7 architecture is not in manifest.
To be able to install it I needed to remove all specified versions of all packages in order to be able to install latest ones.
Needed to replace mysql packages with mariadb and install nodes and npm differently. Eventually installation was ok, managed to started servers and launch localhost:80. Added URL, selected Title and Description, but when it comes to create the feed I get the feed link but instead of the preview I have:
Something wrong. Reload the page or contact us by email...
From the server log I see:
File "/home/pi/pol/pol/server.py", line 347, in render_GET
res = self.feed.getFeedData(feed_id)
File "/home/pi/pol/pol/feed.py", line 153, in getFeedData
with closing(get_conn(self.db_creds, dict_result=True)) as conn, conn as cur:
exceptions.AttributeError: exit

At this point I don't know what else to do.
Pls advise

I didn't see such exception before. So I don't have raspberry pi4 and I can't reproduce and fix it

[sasagr]

Oh. That’s a pity. If there is something that I can do to assist you, maybe some troubleshooting pls let me know. I really would like to make it working.
Otherwise what about the container compatibility with arm7v architecture? Would it make things easier?

[taroved]

Sorry. I have no idea. You can try to debug code with import pdb; pdb.set_trace() but if you have experience in python language

[sasagr]

I would not really know where to put the import pdb; pdb.set_trace(). I tried in feed.py a few lines before line 153 but I did not see prompting during the execution as you can see below.
Unfortunately I m not python coder. If you have any suggestion where to put it and eventually what to look for? Which command to give to pdb, pls let me know, otherwise I understand and I thanks you anyway.
Below the error I see in terminal windows where I executed the downloader.py. manage.py runserver is running in an another terminal window and I don't see any error there.

Hi there... I tried a new installation on rpi3 with ubuntu 18.04 and not debian this time.
Managed also here to get all installed and running but also here I get the same exception error.
I check around and it seems that maybe some lib for raspberry do not support the "with.." properly.
I tried to edit this part of code replacing the "with..." with
conn = closing(get_conn(self.db_creds, dict_result=True))
cur = conn
cur.execute("""select f.uri, f.xpath....

fixing the indentation but I get another error:
cur.execute("""select f.uri, f.xpath as feed_xpath, fi.name, ff.xpath, fi.required
exceptions.AttributeError: 'closing' object has no attribute 'execute'

so obviously I m doing something very wrong.
Can you suggest some alternative lines in this part of code that maybe they will by pass the initial issue?

[taroved]

Sorry. But currently, I have no enough. I will back to the issue but I don't know when

[Wombat2018]

I would like to respond this topic again. It would be really great if a version linux/arm/v7 would be provided to use it on the Raspberry Pi 4 with docker.
