Previously, we would replace block declarations in some contexts with
the variable alone, and decalres the variable higher in the generated
code. Issues arise because whe sometimes try to replace "let b2" with
"b2" but end up matching "let b20" which is incorrect.
This commit fixes that by adding a space to the text that we are trying
to match ("let b2 " won't match "let b20")
Have a GrandParent which controls whether one of its GrandChildren is displayed or not.
First, the GrandChild is displayed. Then, change the state of the GrandParent in order to kill
the GrandChild.
Before this commit the GrandChild is only removed from the DOM, as bdom correctly works.
But it is not destroyed.
After this commit, the GrandChild is correctly destroyed.
Before this commit, portal was a Component, now is a directive.
This commit also clean some unused code, and fix an issue on the clean
optimization when a portal is found in a condition or a loop.
Every use case involving some sort of key set on a component would give birth to a leak in an async context:
- If a key of a component changed, the outdated one was never destroyed.
- destroyed component were never removed from their parent's reference map.
This commit solves both issues, that are tightly linked anyway.
Before this commit, Portal overrode the _render function for its
component node, which means it bypassed the error handling mechanism
that was implemented in that method. It could have been fixed by
duplicating the error handling code as well, but a better solution in my
opinion is to simply override the renderFn function. This is closer to
the actual intent of the portal implementation: wrap the result of the
rendering in a VPortal vnode.
Have a Component which has a Component node, and a dynamic t-call itself having
a Component node.
Before this commit, both children had the same `key`, (as in the key in parent.children, which registers on the parent all its children).
As a result, the scheduler was endlessly hanging.
After this commit, it works as expected.
This means that unrelated ids (eg the id of a template, variable or key)
not longer share the same incrementing counter, meaning that you no
longer see a variable named "v2" unless another variable "v1" was
generated previously, this is also true for block data.
We only use 2 const enums in the codebase, but they are defined in the
output, even though this is not useful in any way. This commit reduces
the final output by about 30 loc.
Have a component which does a render in its onWillPatch, onPatched, onMounted hooks.
Before this commit, the result was incorrect: the second rendering was not taken into account.
After this commit, those renderings are correctly applied at the price of a delayed render when the fiber
is in a critical state.
This commit fixes some issues with falsy attributes not being properly
set/removed in various situations. Also, the behaviour was not
consistent between normal attribute (key/value) and generic attributes
(pair or object)
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.
