I subtle change in the Lino core in order to optimize testing:
lino.utils.diag.Analyzer.show_window_fields() no longer shows dummy
fields. Because it was irritating to see the
lino_xl.lib.cv.LanguageKnowledge.entry_date field appear in the doctests
for Lino Welfare where they don’t want to have this field.
Version mismatch: this is the ‘cffi’ package version 1.12.3¶
[Wed Sep 18 15:37:21.750588 2019] [wsgi:error] [pid 3357:tid 140319710512896] Exception: Version mismatch: this is the 'cffi' package version 1.12.3, located in '/usr/local/lino/lino_local/prod/env/lib/python3.7/site-packages/cffi/api.py'. When we import the top-level '_cffi_backend' extension module, we get version 1.12.2, located in '/usr/lib/python3/dist-packages/_cffi_backend.cpython-37m-x86_64-linux-gnu.so'. The two versions should be equal; check your installation.
Looks as if the cffi in the site’s environment is finding the cffi of the server-wide environment.
But the server-wide Python does not seem to have cffi installed:
# python3 Python 3.7.3 (default, Apr 3 2019, 05:39:12) [GCC 8.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import cffi Traceback (most recent call last): File "<stdin>", line 1, in <module> ModuleNotFoundError: No module named 'cffi' >>>
Why then does it have a file
Why do I have that cffi package installed at all? What does it do? Which module requires it?
What is the difference between
/usr/lib is for modules installed by the system with the
package manager (e.g. with
sudo apt-get python-numpy) while
/usr/local/lib is for modules that you installed yourself system-wide
sudo pip install numpy
After reading this, I tried to install python3-cffi as a system package:
$ sudo apt-get install python3-cffi ... The following NEW packages will be installed: python3-cffi python3-ply python3-pycparser ...
And whoops, the problem is gone! But don’t ask me why…
TODO: review Installing getlino to not use “sudo pip3”, e.g. by always using a shared env which contains at least getlino.
Install eidreader handler on tups¶
I needed to install a custom url handler for beid:// links, so I used the documentation about Installation and reviewed it en passant.
Run the migration script¶
I ran the migration script prod2preview for weleup because I had an operationdatabase error because LanguageKnowledge.use_certificate had not yet been created. Nothing special.
