I have two web2py applications; modules are defined in the first one, and
symlinked from the second one. .
This is the structure (also notice some symlinked models):
applications/app1/
applications/app1/models/0.py
applications/app1/models/0_template.py* ---> symlink to
app2/models/0_template.py*
applications/app1/models/db.py
applications/app1/modules/
applications/app1/modules/globales.py
applications/app2/
applications/app2/models/0.py* ---> symlink to app1/models/0.py*
applications/app2/models/0_template.py
applications/app2/models/db.py* ---> symlink to app1/models/db.py*
applications/app2/modules/* ---> symlink to app1/modules/*
This two applications are two separated mercurial repositories.
Every once in a while, I make some change to one (or both) application,
then I go to the server and I do a hg pull and hg update.
After the hg update, the application shows an *intermitent* error 500 with
this traceback:
Traceback (most recent call last):
File "/home/gonguinguen/medios/gluon/restricted.py", line 227, in restricted
exec ccode in environment
File
"/home/gonguinguen/medios/applications/fundapres_panel/models/0_template.py"
<http://localhost/admin/edit/fundapres_panel/models/0_template.py>, line 3, in
<module>
from globales import Template, VariableConfiguracion, Estilo, Tema
File "/home/gonguinguen/medios/gluon/custom_import.py", line 95, in
custom_importer
return base_importer(pname, globals, locals, fromlist, level)
ImportError: No module named fundapres_panel.modules.globales
In order to get it to work again, I have to restart uwsgi process (that's
what I'm using, nginx + uwsgi).
Restarting uwsgi process solves the problem, but I don't want to restart
uwsgi process every time I do an update.
Notice that the line throwing the error is in models/0_template.py, which
is one of the models that is symlinked.
Also, I don't understand why *the error is intermitent* (but it's there,
the error shows up once every two or three calls).
And one last thing: *the error appears even if the update doesn't update
anything.* Even if nothing has changed in the repository, if I do an
update, the error appears and I'm forced to restart uwsgi process.
I'm not using track_changes or anything like that.
I'm using the simple form of the mercurial update, just "hg update", no
parameters provided.
I know it's possible to import modules in other ways (using __import__ or
importlib), but I've tried that and the problem remains. Any suggestion
will be appreciated. Thanks!
