This commit fixes 2 issues specific to the firefox version of the
extension:
First issue concerns the computation the position of the
border between the subwindows of the components tab which could go
terribly wrong due to the fact that the innerwidth of the window is
implicitly set to 10 when the owl devtools window is hidden.
Second issue comes from changes in the runtime.onMessage method of
browser which now requires to directly return the response instead of
using the sendResponse method.
Also perform a little cleanup on usage of browserInstance and in the
manifest.
`useEffect` type is not compatible with later versions of Typescript.
(I tried with Typescript 5.2, I didn't check which specific
version had the breaking change)
This prevents other projects using owl (such as o-spreadsheet) to
upgrade their own version of Typescript.
`<T extends [...T]>` raises the two following errors:
`Type parameter 'T' has a circular constraint.ts(2313)`
`A rest element type must be an array type.`
This commit adapts the layout of icons in the UI to be more intuitive
and also adds some feedback on hover on some elements for clarity. Also
fixes a bug where an object line could be toggled on select.
This commit prevents the base object prototype from being unfolded when
the env of a component gets unfolded since it does not contain useful
information.
This commit ensures that search results are properly updated when the
components tree is updated so that it remains coherent if search results
appear or disappear from the view.
A few corrections to make the example more realistic:
- The component has no `error` property, so the writer probably meant `state.error`.
- The "content" slot is not being set, and "default" does the job in this case.
- The closing tag was missing in the `ErrorBoundary`'s template.

- [IMP] devtools: add svg elements detection
- [FIX] reactivity: do not notify for NOOPs on collections
- [IMP] app: export apps set as static property
- [IMP] runtime: do not check template equality outside dev mode
- [FIX] runtime: properly support t-foreach on strings
This commit extends the detection of component related dom elements to
svg elements in the page so that they can be searched and highlighted
correctly with the devtools.
Previously, if a reactive was observing the presence of an item in a
set that was originally not present, it would get notified when that
item was "deleted" from the set (even though there was nothing to delete
and the set did not change). The same applied to the key already being
present and then being "added". The same thing occured with Map, both
for presence but also for values (setting a key to the value it was
already set to would notify).
This commit fixes that.
Before this commit, Owl would export the list of apps in a global object
`__OWL_DEVTOOLS__`. However, it is sometimes useful to be able to
access that set, even outside of the devtools (for example, to register
templates in all active apps).
closes#1515
When defining a template with a name that the template set already
contains, we currently always check whether the template is the same and
throw an error when it's not. This is potentially expensive as it can
involve serializing a pretty large XML document. This check is only
supposed to help during development so this commit disables this check
outside dev mode.
Previously, support for iterables was added to t-foreach. The idea was
that anything that you can spread or on which you can use for..of would
be supported. Due to an implementation mistakes, strings, which are
iterable were not supported because we checked that the typeof the
iterable was 'object'.
To fix this, we coerce the iterable to an object and check whether that
coerced value has a Symbol.iterator property, which is what happens
behind the scenes when using for..of or spreading a primitive.
Closes: odoo/owl#1503
Firefox will not serialize the xmlns attributes of node inside
XMLDocuments, see https://bugzilla.mozilla.org/show_bug.cgi?id=175946
it will only output an xmlns attribute if the node being serialized has
a non-null namespaceURI.
When compiling templates, we currently use a special attribute,
"block-ns" to keep track of the namespace, but we do not make use of the
namespace to create the elements that will be serialized to the compiled
block string. This causes a difference in behaviour between Chrome and
Firefox: since we end up with an Element with two attributes: the
block-ns attribute and the xmlns attribute. Chrome will serialize both,
but Firefox will only serialize the block-ns because the Element does
not have a namespaceURI.
To fix this issue, we get rid of the block-ns magic attribute
completely, and use xmlns instead. We also use the namespace when
creating intermediate elements that will be used to create the
serialized block string: the namespace is only used to create the
elements but *not* set as an attribute, as this would cause chrome to
serialize it twice, causing a duplicate attribute error when parsing it
further down the line.
When creating the template element for the block at runtime, the xmlns
attribute is used both as the namespace with which to create the
element, and set as an attribute, this doesn't cause issues when
serializing later because the namespaceURI is never serialized as an
attribute when serializing an HTML document[1], so we avoid the
double-serialization in Chrome, and when doing HTML serialization,
Firefox will correctly serialize the attribute.
It's desirable that the xmlns is set as an attribute to allow users to
use owl to render SVG, and then use the HTML serialization of it as a
SVG even outside the context of an HTML document (eg to generate an SVG
file or an SVG data URL).

Because the default content of a t-call is compiled before the block of
the t-call is created, the default content can sometimes incorrectly be
treated as though it is at the root of the template. This causes various
issues, in the case of a t-if, the default content will just replace the
t-call entirely when truthy, and when falsy the template will not return
anything, leading to a crash. Similar things occur with t-foreach and
t-out with a default content.
This commit fixes that by moving the block creation for the t-call ahead
of the compilation of the default content. In doing so, it makes the
context attribute "preventRoot" obsolete: the purpose of this attribute
is to somehow make the code aware that the root of the template will be
defined later, but because it wasn't propagated everywhere properly it
caused this issue. Now that the root already exists before we compile
the default content, we don't need it anymore.
This commit fixes the handling of the inspected path in the
getComponentsTree method so that it is reset when the given one does
not exist anymore. It solves a crash of the method anytime this would
happen which would prevent the tree from updating correctly.
In odoo/owl#1352 we added support for using t-foreach on Map objects,
maps should behave the same as objects where keys are available under
the name specified in t-as and values under that same name with the
suffix `_value`. Unfortunately, because the code for objects was written
in a confusing way (values were stored in a variable named `keys` and
vice versa), the implementation for Map was incorrect and keys and
values were swapped.
This commit fixes that and rewrites the code to be less confusing: keys
are extracted from the variables `k_block` and values from `v_block`,
which swaps the behaviour, and the code to prepare a list from an object
now extracts the keys in `keys` and the values in `values`
Previously, when a template failed to compile because of a syntax error
(typically because we don't do any syntax checking when compiling
expression, allowing invalid expressions to be transpiled successfully),
the error reporting was very minimal: you would only get the error
message itself (eg: "Unexpected token") with the stack information of
the error pointing to the call to `new Function` in owl, which is not
very useful.
This commit catches the compilation error and completes it with
information about the template name when available, and also adds the
generated code to the error message, allowing the user to just
copy/paste it in their web console or code editor to get a more precise
location for the error.
Before this commit, the App destroy method would not destroy everything
synchronously. The code scheduled a flush, which is asynchronous, to
finally clean up the task lists, and destroy the cancelled nodes. But
this is not really good for tests: we need a stronger guarantee that
nothing will happen after the destroy.
With this commit, we simply call the processTask method immediately
after destroying the root component, so all cancelled nodes will be
destroyed immediately.
Before this commit, the release script would build the code, then update
the version number, so the released code would have the previous release
number instead of the current.
Before this commit, the template parser would allow using t-esc on a
component tag (<MyComponent t-esc="expr"/>) but would incorrectly ignore
the component when parsing a t-out: <MyComponent t-out="expr"/> would be
parsed as <t t-out="expr"/>
This commit solves the issue, and also, moves the `t-out` parsing code
next to `t-esc` so they have the same priority relatively to other
directives.

Before this commit, most of the time, components are destroyed when the
virtual dom is patched and a component node is removed. However, since
Owl is asynchronous and a component may take some time to get ready
(with onWillStart), it can happen that a component is created, then
before it is ready, it is recreated. In that case, the initial instance
has to be destroyed.
Before this commit, the destroy operation was done immediately, when we
cancel the current fibers. However, this means that we cannot have a
guarantee between micro task ticks that a component has not been
destroyed in the meantime.
For example, in Odoo, it is common to use the rpc service, which will
throw an error if called by a destroyed component. But because of the
possible destruction of a component at any time, the following code is
unsafe:
async loadSomeData() {
// guaranteed to be called when component is alive
await Promise.resolve();
// however here, component may have been destroyed
this.rpc(...)
}
So, to prevent this issue, we can slightly delay the destroy operation.
It is not entirely trivial, since we need to find a way to neutralize
the component in the meantime. But it seems like performing all that
kind of operation at the "commit" phase (so, the request animation frame
callback) makes sense to me.
So, this commit modifies the code to add a new component status
(cancelled) and use it to cancel components that are waiting to be
destroyed. These components will then be destroyed as soon as the
requestanimation frame starts, before all other dom operations.
Currently the implementation of batched is quite complicated and
difficult to read. This is because this approach tried to block all
calls at the same point and then only let the first one go through, but
an alternative approach is to simply throw away the calls that are made
after the first one has been scheduled. This change makes the
implementation much simpler to understand.

Before this commit, owl parser would ignore the `.number` suffix on
<select> options. I do not see a good reason for that, and it prevents
some legitimate usecases.

This commit fixes a crash in the retrieval of the components tree which
happened when the first app did not contain a root node. The default
inspected component is now set to be the first root component found in
the apps.
This commit first fixes how object prototype are detected so that it
won't stop as soon as the constructor name of the object is "Object".
This allows displaying every single prototype encountered and closes
https://github.com/odoo/owl/issues/1467.
This commit also improves how the env of a component is displayed by
expanding its chain of prototypes by default while keeping its keys lit
as long as it is their first occurence in the chain.
This commit fixes the three following issues:
- Symbols could never appear in shortened display of objects
- Objects which contained only symbols as keys would be considered to be
empty and therefore not expandable
- Symbol value edition would create a new property on the object with
the stringified symbol as key instead of updating its value
closes https://github.com/odoo/owl/issues/1464
Since we now omit some observed objects when listing subscriptions, the
index of the subscription is no longer the index of the raw
subscription. This causes issue with the resolution of object paths when
they are inside a subscription. This commit fixes that by adding the
index to the raw subscription.
We also need to adapt the code that traverses the old tree, since the
index of the subscription in the component is no longer the same as the
index of the subscription "child" in the object tree.
Previously, the keys were displayed separately from the target, on top
of being displayed in bold inside the object when unfolded. This is
redundant, and in most cases you have to unfold the object anyway
because there are more keys observed than can be displayed.
The only "key" that cannot be displayed in bold inside the object is the
"key changes" magic key. This commit replaces it by a small +/- badge on
the right of the object's short content.
This commit also stops displaying observed object that are nested inside
other observed objects at the top level, as it can be confusing, and it
also heuristically gives a name to observed objects: if the observed
object is a property of the component or one of its props it will be
named accordingly, if not it will be named `[unknown]` (which may happen
when reobserving reactive objects inside a service or inside the env,
but is pretty rare in practice).
This commit changes the moment when all methods that need patching
to handle events are actually patched: the complete method of RootFiber
is now patched at devtools startup (when the tab owl tab is opened) and
every other method is patched at first activation of the event recording
functionality. This makes sure that the devtools will have no impact on
performance whatsoever when they are not directly put in use.
