Continued to search the reason of #150 (public web interface for lino_noi).
Fixed one of the side effects announced yesterday: icons were not properly displayed since their URLs have changed.
Uugh! Leif Azzopardi and David Maxwell write about software patents. After explaining how “Netscape programmer Lou Montulli took the concept of a magic cookie and applied it to web communications.”, they add “Of course, with such a great idea came a software patent - and you can read US patent 5774670 that was submitted by Montulli himself.” No, it is not “of course” at all. The greatest ideas in history of mankind are not patented.
I noticed that my local
djangosite_local.py had been setting
lino.core.site.Site.site_prefix was something else than the
default. Since this trick seems a general need when hosting several
Django projects under the same hostname, I added it to
In a stackoverflow thread titled Django (Python) problem with sessionid, Chris2048 wrote “I had a similar problem, and I fixed it by setting SESSION_COOKIE_NAME to something other than the default ‘sessionid’. I think google analytics might have been clobbering the cookie somehow.”
I don’t use any google analytics (AFAIK), but it seems that modifying
SESSION_COOKIE_NAME from its default sessionid to
ssid solved the problem.
After changing the content of
browser had two cookies for host 127.0.0.1, both called sessionid,
one with path
/ and the other with path
/admin. And it seems
that Django writes to the cookie with path
/admin, but the
browser answers always with the “top-level” cookie, i.e. the old one
Now another question is how to avoid this problem in the future?
Answer: stop to misuse the site_prefix attribute for specifing that the “Lino admin interface” is not at root.
I released to lino-framework.org because everything seemed to work. But there is obviously yet another problem (“SITE.kernel is None”) which occurs only in a multi-threaded environment. So I reverted to a (hopefully) good version:
git rev-list -n1 --before=2015-04-25 master | xargs git checkout
The output of above command is somewhat strange:
Note: checking out '1ca11541fdcb9da85e1331e2de237c38c28860dd'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b new_branch_name HEAD is now at 1ca1154... http://luc.lino-framework.org/blog/2015/0424.html
Fix the “SITE.kernel is None” problem
Change Apache configurations so that it serves the static files. I hope that I can serve all static files from one place.
