+[[done]] (in this branch); fixed removing email notification support!
+
I was suprised to receive two mails from ikiwiki about one web edit:
1 F Oct 30 To joey+ikiwiki update of ikiwiki's plugins/contrib/gallery.mdwn by http://arpitjain11.myopenid.com/
1 F Oct 30 To joey+ikiwiki update of ikiwiki's plugins/contrib/gallery.mdwn by http://arpitjain11.myopenid.com/
The first of these had the correct diff for the changes made by the web
- edit (00259020061577316895370ee04cf00b634db98a).
+edit (00259020061577316895370ee04cf00b634db98a).
But the second had a diff for modifications I made to ikiwiki code
around the same time (2a6e353c205a6c2c8b8e2eaf85fe9c585c1af0cd).
Ikiwiki's own locking prevents this from happenning if both commits are web
edits. At least one of the two commits has to be a non-web commit.
+
+----
+
+A related problem is that if two commits are made separately but then
+pushed in together, the commit code only looks at the HEAD commit, which
+is the second one. No notification is sent for the first.
+
+----
+
+Based on all of these problems with using the post-update hook, ikiwiki
+should be changed to use the post-receive hook, which provides enough
+information to avoid the assumuptions that led to these problems.
+Transitioning existing wikis to using a new hook will be interesting. Also,
+this hook is only present in git >= 1.5.0.7.
