[Cppcms-users] Continued discussion on bug 3536452 - transaction in progress

[<ele...@ex...>]

I didn't want to re-open the bug again, but there's a still an idea i'd
like to discuss.

Artyom mentioned creating a "custom" transaction class to support
something like BEGIN {EXCLUSIVE|IMMEDIATE}

An idea would be to add a default constructor to cppcdb::transaction so
that users can inherit from it instead of creating standalone transaction
classes.

The current constructor cppdb::transaction(cppdb::session&) calls begin()
within itself so it cannot be modified.

Maybe we could also add a cppdb::transaction_base interface class with
virtual  commit() = 0 and rollback() = 0 functions.

If Artyom thinks this might be useful, I can create a patch to support
such functionality.
