Before this commit, it was logged for every app created, which is
annoying in odoo: because of the compatibility layer, there are many
apps being created.
With this commit, component only render child
components if they have different props (shallow
equality). Otherwise, we trust the reactivity
system to make sure that all impacted components
are updated
Owl provides a way to manage errors occuring in component lifecycle
methods. However, before this commit, these errors were not always
logged or visible, which is very annoying in the common developer
workflow (doing something, checking it works, seeing no error but a
broken interface).
In this commit, we make sure errors are logged/throws in all cases:
- if an error occurs in a mounting operation => the promise is rejected
(which will log the error)
- if an error occurs after the mounting operation and is not handled by
any error handlers => the error will be logged (with console.error).
Also, in that case, this commit adds a warning to explain that owl
destroys the root component, which will help developers understanding
what happened.
Before this commit, when defining a getter in the env passed to the App,
the value was read, losing the definition of the property.
After this commit, declaring a getter in the env works as expected:
the property stays a getter.
Before this commit, class inheritance when using the onError hook was unclear nay wrong.
After this commit, error handlers are called from the bottom up in the inheritance hierarchy.
If a handler doesn't rethrow the error, the handling stops there and no other handler is called.
If a handler does rethrow, the handlers declared in a parent class are executed.
