Cockatrice: Could not update cards database under Linux

[joeved]

Hi all,

Since some weeks, I cannot update my cadrs database. The download seems to be correct but just after the 100%, I have this popup message "The card database updater exited with an error: crashed".
I try to download the file but this is the same problem.

My OS is Raspbian (Debian) and my computer is a Raspberry.
I compile Cockatrice. The version shown is: 2.6.3 (a719e3b).

Have you any idea to solve my problem ?
Thanks a lot.
Joe.

do you have a coredump or stack trace for oracle?

[joeved]

Yes probably. Where can I find it ?
If you want some version products, tell me ?

For example: CMake is 3.13

[joeved]

... and I don't have oracle directory into /var/opt. Is it important ?

[joeved]

When I launch oracle from cmd, after loading the local file, I have this message:
GtkDialog mapped without a transient parent. This is discouraged.
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Abandon

I'm afraid that could mean that your Raspberry doesn't have enough memory to run oracle.
Recently oracle has been updated to switch from mtgjson (the card database source) v2 to v4.
While the v2 file was about 31 MB, the v4 file is more that 200 MB i size, and probably loading that file into memory, unzipping and parsing it fills up all the available RAM on the Raspberry.
A possible workaround is to add a swap file/partition to your Raspberry and see if it works.
Here's a thread i found about how to do it on raspbian: https://raspberrypi.stackexchange.com/questions/70/how-to-set-up-swap-space , the defaults seems to be 100MB, try to add a few hundred MBs to that and run oracle again.

Great idea, thanks. I will try that tomorow and I'll let you know.

[joeved]

It works !! Thanks you. No as easy as I thought.

In /etc/dphys-swapfile:
1- Uncomment CONF_SWAPFILE=/var/swap
2- Uncomment CONF_SWAPFACTOR=2 to have dynamic swap file.
3- Check that CONF_SWAPSIZE=100 is commented
4- Restart the swapfile process: /etc/init.d/dphys-swapfile restart

After that, all is possible !!

Thanks again.

Happy to see it working for you. 👍

[joeved]

Yep, hope it will help someone else.

[tooomm]

You could add it to the wiki maybe, but not sure where...

[ctrlaltca]

To the Raspberry Pi documentation maybe :)

[tooomm]

The pi compilation instructions?

We have that? nice :)

[tooomm]

Do you mind explaining your solution and add it as a hint there? @joeved

[joeved]

Yes, if you want. I will try but how can I edit this page (https://github.com/Cockatrice/Cockatrice/wiki/Compiling-Cockatrice-(Linux)#raspberry-pi) ?

[joeved]

I saw an Edit button on the top, will try a small modif and do more of this is good !!

[joeved]

It's done. Check and tell me if all is ok for you. Thanks.

[tooomm]

Awesome, thank you!

[joeved]

;) thanks you for your help too.
