I am considering adopting "ExtFile/ExtImage" product and bring it to
zope 2.13. The sourcecode is easy enough, although I suspect tons of
"weirdness" is derived by legacy. A complete rewrite is an option, I
should not maintain code I don't understand.
Zope documentation is really incomplete and very old so I wonder about
1. What interfaces (I only care about Zope 2.13, no legacy) should I
look at to participate in transactions?. I need to know if a
transaction I was involved in was aborted (to rollback external
changes too) or committed (to activate cascading actions previously
"queued" during the transaction progress). Old ExtFile produc uses TM
(transaction manager) from ZSQLmethods, but it is not in core Zope, I
need to install an extra package, and I guess there is a more
"official" and supported way.
2. How to participate in copy&paste?.
I see stuff like "event" listening, but I can not find any
documentation about them, beside just reading the source code.
Any pointer and suggestion are welcomed :-).
