Cannot easily see whether invoices are registered¶
I worked on #3430. This was less easy than I had imagined.
The basic plan is to change
Voucher.__str__() so that a voucher is
displayed as journal, number and year (e.g. “SLS 1/2019”) only when it is
registered, and that otherwise the internal primary key is displayed
This change wasn’t that easy because the match becomes valid only when the
voucher state is set. Which means that we cannot call
during the process of registering when collecting the movements to generate.
That’s why I removed get_default_match and say now that str(voucher) or
str(voucheritem) returns the match, and when collecting the movements, I set
their match to the object itself, not a string. Django will call
that object when it actually stores the movement. Is that hackerish? But it
even fixed a problem with matches
that was visible in about : Site-wide search but
that nobody had noticed so far.
Miscellaneous changes en passant:
New plugin attribute
lino_xl.lib.vat.MovementsByDeclarationtable now also shows the VAT class of every ledger account, making diagnostics more intuitive.
Hobbit says “RuntimeError: populate() isn’t reentrant”¶
I also worked on #3178.
Oops, I saw that my quick fix yesterday (
Actor._get_handle) broke everything. I can’t store the
handle instance only after setup because once a handle has been instantiated,
subsequent calls to
_get_handle() should return that instance. They occur
setup_handle(). Which also means that this change is less
probable to fix the problem.
TIL : Having more than 20 years of experience as a developer doesn’t exempt you from having to run the test suite before publishing a change, even if the change seems trivial.
In the afternoon the original problem was again occurring on hobbit. I looked at the error logs and saw:
[Thu Dec 26 10:38:03.007191 2019] [wsgi:error] [pid 31665] [remote 126.96.36.199:53356] mod_wsgi (pid=31665): Target WSGI script '/usr/local/python/.../apache/wsgi.py' does not contain WSGI application 'application'.
wsgi.py scripts for hobbit and jane were still using the old
lino_local.py. They said:
import sys ; sys.path.append('/usr/local/python') from lino_local import setup_wsgi ; setup_wsgi(globals())
def setup_wsgi(globals_dict,*args,**kw): filename = globals_dict['__file__'] home_dir,tail = split(dirname(abspath(filename))) assert tail == 'apache', "%r is not apache" % tail setup(home_dir, *args, **kw) #import django.core.handlers.wsgi #globals_dict.update(application=django.core.handlers.wsgi.WSGIHandler()) from django.core.wsgi import get_wsgi_application try: application = get_wsgi_application() globals_dict.update(application = application) except RuntimeError as e: print(e) print("Wsgi application is not yet ready")
I changed them to what getlino does:
import os, sys sys.path.insert(0, '/usr/local/python') os.environ.setdefault("DJANGO_SETTINGS_MODULE", "lino_sites.hobbit.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application()
I also noted that the apache subdir of hobbit was not writable for www-data.
monit package in Debian Buster¶
In getlino I changed the debian dockerfile : FROM bullseye instead of from buster. Because I started to believe that indeed monit will never be in buster. Which raises the question of whether and how to upgrade a production site from buster to bullseye. Or should we rather use a backport?
Not sure, but the following two commands in the test suite were hanging and got reactivated after pressing ENTER twice:
. ~/lino/env/bin/activate && getlino startsite noi mynoi1 --batch --dev-repos "lino xl noi" ===== . ~/lino/env/bin/activate && getlino startsite cosi mycosi1 --batch --dev-repos "lino xl cosi" =====
Another bug in
I found and fixed a bug in
lino_xl.lib.vat : Lino didn’t compute
correctly when you defined a
DeclarationField with a condition on
DeclarationField.vat_classes which mentioned only vat classes to be
excluded (i.e. no VAT class without an “!”). Same for
