## Reference to the module’s source code¶

Some days ago I thought that the sentence with the reference to the module’s source code (which is added by atelier.sphinxconf.base.autodoc_add_srcref()) whould better be the first sentence of the page because it can be difficult to find. But now I (re)discovered we we must add it after the module description (not before): it is because also autosummary gets the docstring processed by this handler.

During a routine upgrade on lino-framework.org I had a series of error messages like the following:

django.db.utils.OperationalError: (1025, "Error on rename of './welfare_chatelet_demo/countries_place' to './welfare_chatelet_demo/#sql2-3bd4-23777' (errno: 152)")


It seems that this might come when tables have different storage engines, so I changed the system default from MyISAM to InnoDB (see MyISAM or InnoDB?) in my /etc/mysql/conf.d/.keepme file:

[mysqld]
# default-storage-engine=myisam
default-storage-engine=InnoDB


And then I had to drop and create each concerned database.
