Issue after latest in application update...

[quella]

I have been running the software for a few months (Chrome) and using the built-in web application update tool in the settings. Today when I did an update and apply, I was logged out of the application's web interface. I tried to access to application again using retry, but I kept getting an Error 500. I opened the web interface again in a different browser (Safari) where I was prompted with the login screen. Once logged in, I was only presented with a blank white page, no feed or other data on the page. I did an update to my Pi OS, reboot, and still get the same behavior of a blank screen after I login to the application. I cleared the cookie on Chrome and seem to not be able to get past the issue after the update was applied; the system only runs FreshRSS, no other software.

I tried to do a CLI export of my feeds using the CLI but I get an error shown below. Happy to blow away the setup and start fresh, but I would need to first get an export. Help with either to get me back up would be welcomed.

Following this CLI info from Git: https://github.com/FreshRSS/FreshRSS/blob/master/cli/README.md

When doing a CLI export I get the following:

FreshRSS exporting OPML for user “quella”…

@quella I've changed recently the auto-loading process. It might be a cache related problem.
I've run the following command without problem:
docker exec freshrss-dev ./cli/export-opml-for-user.php --user alexis

Could you try again after clearing your cache?

Hello @quella
Thanks for the report and helping us testing the development version.

If you have installed via git, you can revert to a slightly older point, such as da4121c

Otherwise, fix coming soon :-)

@aledeg I can reproduce:

docker exec freshrss ./cli/export-opml-for-user.php --user freshrss

[aledeg]

@Alkarex I tried with your command and I cannot reproduce. Could you clear your cache and restart your container?

[quella]

I did clear my cache in Safari and I get the same results after applying the latest update. I can do an "About" from the login page and I seems to have access to some of the functions (update included), but a few (Archive) and the feeds show only a blank white screen. Here are a few screen shots if they are helpful.

White Screen when looking any feeds or archive...

[aledeg]

@quella Oh! I mean the application cache, not the one in your browser. Sorry, I was not clear.
Please remove everything from the data/cache folder with the exception of the index.html file.

[Alkarex]

@aledeg I suggest we revert #3283 for now, and make a new test including your upcoming changes #3299

[aledeg]

@Alkarex If you want to, I have no problem. But it works after clearing the cache and restarting docker.

[quella]

So I did clear out a number of .spc files in the application's cache folder leaving the index.html intact. Only thing in that directory. I did a logout, login from the web browser and I sill seem to get the same behavior of the clean screen after I authenticate correctly to the application.

After clearing the cache directory, do you want me to reboot the system as well? Again, it is the only thing running on this Pi. Happy to troubleshoot or try any suggestions.

@aledeg It seems to fail consistently with at least MySQL. Seems to work with SQLite.
Here is a fresh new Docker + volume:

P.S.: And I only tested your PR with SQLite

[Alkarex]

Actually #3297 needs to be reverted to.
Let's revert to a working state and re-introduce those changes more carefully :-)

Edit: done

[Alkarex]

@quella Could you please try again with the very latest code?

[quella]

If we did a revert, I can try doing one update from the application screen or via cli git. Just let me know when ready.

[Alkarex]

It is ready. Try the same way you did the previous update, if that works

[quella]

I'm back up and running after doing an Update. Thanks Guys!

[Alkarex]

Good :-)
Let's close here, and could you please resubmit your PRs @aledeg when ready (sorry for the extra work), starting with the safest bits such as extracting the classes in their own files

[aledeg]

@Alkarex I've found out the problem. There was a typo in MysqlPdo. I think we could revert the reverts.
and just fix the typo

[aledeg]

or do you want me to resubmit those PR completely ?

[Alkarex]

@aledeg Nice that you found the problem :-) The error messages were also quite cryptic (e.g. Undefined array key 1 in /var/www/FreshRSS/lib/autoload.php on line 50), something to test as well.
