Error loading psycopg2 module: No module named ‘psycopg2’. OMG I am stupid. Hamza actually fixed that bug but I undid it because I didn’t notice at that moment the difference between apt packages and pip packages… Yes of course: okay we select the db-engine only once per server, but startsite still must install the corresponding pip packages in startsite for every site.

Should we install psycopg2-binary or rather psycopg? –> “The psycopg2-binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.” (https://pypi.org/project/psycopg2/)

This caused an errror “You need to install postgresql-server-dev-NN for building a server-side extension or libpq-dev for building a client-side application.” –> I added libpq-dev to the apt_packages of postgresql dbengine.

The getlino.utils.Installer.runcmd() didn’t fail when the subprocess failed. Fixed.

More changes in the .travis.yml file after reading Travis docs. No need to specify a python version as each Ubuntu distro has its default version. Travis offers only Ubuntu images, no pure Debian.

Fixed a problem with the postgresql database setup (it was adding an “;” at the wrong place).

Running inv prep in a project without demo projects

The inv prep command in getlino didn’t execute the prep.sh script because getlino has no demo projects. Instead of saying “inv prep test” we must say “./prep.sh ; inv test” in the .travis.yml file. But that’s suboptimal. inv prep should “run preparation tasks that need to run before testing (but only once for all tests)”. When I run “pp inv prep test” it should rebuild the images. I should not be forced to remember running prep.sh manually before “pp inv prep test”. So we have now two config settings for inv prep: prep_command and demo_prep_command.

Released Atelier 1.1.14 (Changes in atelier) for testing it on travis for getlino.

Telling Docker where to store images

I am getting system warnings because Docker fills up my root filesystem.

https://stackoverflow.com/questions/19234831/where-are-docker-images-stored-on-the-host-machine

But how to configure the docker daemon on Ubuntu?

https://docs.docker.com/storage/storagedriver/ https://docs.docker.com/storage/storagedriver/select-storage-driver/ https://forums.docker.com/t/how-to-delete-cache/5753/2

Finally I just said:

$ docker system prune

Which answered:

WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache
