Yes, common problem with Composer. That’s the composer create-project which have problem because there is too much commands done at the same moment. It’s the reason, normally, I would prefer to git clone first and then to do a composer install (it’s what I did in the old Refactoring github branche ).

Other solution : do a memory_limit.

PS: the rpi has very often this problem and even big servers which have RAM and SWAP (surely even my server who have 12GB RAM and 24GB Swap).

tituspijean · February 20, 2018, 10:41pm

@frju365, there is actually already a -d memory_limit=-1 in my exec_composer… and I totally missed out on your modifications in your branch (i.e. how to throw away some good work), sorry !

@Issa, thank you for persevering in trying to install the app. Let’s try something. Can you clone the repo branch patch-memory I have just pushed and trying installing it ? Let’s see if it will be more gentle with your servers’ memory.
EDIT: OH WAIT, I thought it was Flarum’s install that crashed, it’s actually the sso extension’s.

Hello;

so i try this :

https://github.com/YunoHost-Apps/flarum_ynh/tree/patch-memory
i can’t install it :

frju365 · February 26, 2018, 5:09pm

You will need to use Command line. Branch are not supported on the Admin interface.

Use :
sudo yunohost app install https://github.com/YunoHost-Apps/flarum_ynh/tree/patch-memory

Issa · February 26, 2018, 5:42pm

Thanks but not working :

Can you do df -h and give the result of the command ? And could you see if you have a Swap partition with sudo fdisk -l ?

You have no swap partition… perhaps add one swapfile and see if it works. To add one, see : Swap or not swap on an SDcard? . (Perhaps you added one already…)

Issa · February 26, 2018, 5:57pm

with sd card too dangerous

if i can found a way to add a usb harddisk attached on the raspberry ?

using sdcard only too boot and the hardisk for evry else

this is a problem

frju365 · February 26, 2018, 6:02pm

We did documentation in french ( we didn’t translate it yet) to mount an HDD (or USB) in a computer. https://yunohost.org/#/external_storage_0_intro_fr (there is Nexcloud writtent but it’s ok for any other apps too).

Issa · February 26, 2018, 6:05pm

the how to is not finished, i have some blank page with link of the different step

frju365 · February 26, 2018, 6:10pm

yeah… a little bug apparently. In fact it’s finished, you can see :

It’s weird…

Issa · February 26, 2018, 6:31pm

Thanks

i m looking this page

for noob like me need more information on how prepare disk

For a linux we need :

Swap partition
Data partition
i think we need an other but i don’t remember

frju365 · February 26, 2018, 6:33pm

no. But you can separate ‘/’ (root of linux) in different partitions : for example one for /var, one for /home, one for /tmp, /boot… but it’s more difficult.

Issa · February 26, 2018, 7:45pm

yeaaa j’ai reussi à ajouter mon disque dans le FSTAB,

mais maintenant c’est pas trés clair le comment mettre toute les données de la sd card sur le disque dur ???

ok so now how create a swap ?
how add all my yunohost on the HDD usb and not using the sd card ?

thanks

information of my partition now :

du coup j’ouvre un autre topic car on sort de l’information de flarun ici

sauko · March 5, 2018, 11:46am

Hi. cannot install it.

[InvalidArgumentException]
Warning: Could not find package tituspijean/flarum-ext-auth-ssowat in a version matching 0.4.x-dev

both from yunohost admin panel and terminal, both master and memory patch branch.

Salud

tituspijean · March 6, 2018, 9:02am

Hi !
I messed up with Packagist, and the installation script indeed could not find the 0.4 version. Can you try again directly from the repository ? I will make a PR to update the community.json.
For the next version I will try to include the extension directly in the package, and not rely on packagist to install it.

Edit : PR made. https://github.com/YunoHost/apps/pull/434

Issa · March 25, 2018, 7:25pm

Hello,
