:date: 2020-10-20 ========================= Tuesday, October 20, 2020 ========================= Lino Voga ========= I had a quick :ref:`voga` demo session with Arnold. We observed that the voga demo project has no presences at all at the moment. And as I expected this was caused by a change for some other customer: Course lines must now have a guest role specified if you want them to fill the guest of calendar events. When I did this change, I didn't care about voga and blindly adapted the doctests to match the new results without noting that this was anormal. I then discovered another subtle problem: Voga permits to have several enrolments for a same person in a same course, provided they have separate date ranges. Since this is a higher level integrity constraint, we remove that database level unique clause. :ref:`lf` is again slow ======================= I started to setup a second front end for the voga1e demo site on :ref:`lf` (according to the instructions in :ref:`hosting.multiple_frontends`) and fell again into :ticket:`3825`. As usual, the server seems to "freeze" as soon as I ask it to do something:: $ pip install -U lino lino_xl lino_cosi lino_voga lino_noi lino_react Collecting lino Downloading lino-20.10.0.tar.gz (10.1 MB) |████████████████████████████████| 10.1 MB 151 kB/s Collecting lino_xl Downloading lino-xl-20.10.1.tar.gz (3.2 MB) |████████████████████████████████| 3.2 MB 13.0 MB/s Collecting lino_cosi Downloading lino-cosi-20.10.0.tar.gz (608 kB) |████████████████████████████████| 608 kB 12.2 MB/s Collecting lino_voga Downloading lino-voga-20.10.0.tar.gz (101 kB) |████████████████████████████████| 101 kB 3.7 MB/s After some time it stayed stuck... Maybe it is because LF is a "Sandbox" server. OVH says: Instances with shared resources (Sandbox) are suitable for testing, verifications and development environments. Their performance may vary slightly over time. :: $ ps -o pid,user,%mem,command ax | sort -b -k3 -r PID USER %MEM COMMAND 18137 mysql 6.4 /usr/sbin/mysqld 31491 www-data 6.2 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/voga1e/nginx/uwsgi.ini 2319 www-data 6.2 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/voga1e/nginx/uwsgi.ini 6605 www-data 5.9 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/noi1r/nginx/uwsgi.ini 23921 www-data 5.7 python /usr/local/lino/lino_local/noi1r/manage.py linod 23916 www-data 5.6 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/voga1e/nginx/uwsgi.ini 24172 www-data 5.6 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/cosi1e/nginx/uwsgi.ini 6895 www-data 5.5 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/noi1r/nginx/uwsgi.ini 23923 www-data 5.5 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/noi1r/nginx/uwsgi.ini 24171 www-data 5.0 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/cosi1e/nginx/uwsgi.ini 23919 www-data 4.5 /usr/bin/uwsgi --ini /usr/local/lino/lino_local/cosi1e/nginx/uwsgi.ini 19552 www-data 4.5 python /usr/local/lino/lino_local/cosi1e/manage.py linod 699 list 1.9 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=VirginRunner:0:1 -s 698 list 1.9 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=OutgoingRunner:0:1 -s 694 list 1.6 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=IncomingRunner:0:1 -s
