Always treat ComponentState subclasses as mixin, and explicitly pass
`mixin=False` in `.create` classmethod when intentionally creating a substate.
This allows a "base" ComponentState to have subclasses that also work as
ComponentState themselves.
Fix#3368
* add support for lifespan tasks
* allow passing args to lifespan task
* add message to the cancel call
* allow asynccontextmanager as lifespan tasks
* Fix integration.utils.SessionStorage
Previously the SessionStorage util was just looking in localStorage, but the
tests didn't catch it because they were asserting the token was not None,
rather than asserting it was truthy.
Fixed here, because I'm using this structure in the new lifespan test.
* If the lifespan task or context takes "app" parameter, pass the FastAPI instance.
* test_lifespan: end to end test for register_lifespan_task
* In py3.8, Task.cancel takes no args
* test_lifespan: use polling to make the test more robust
Fix CI failure
* Do not allow task_args for better composability

* Allow `Component.add_style` to return a regular dict
It's more convenient to allow returning a regular dict without having to import
and wrap the value in `rx.style.Style`.
If the dict contains any Var or encoded VarData f-strings, these will be picked
up when the plain dicts are passed to Style.update().
Because Style.update already merges VarData, there is no reason to explicitly
merge it again in this function; this change keeps the merging logic inside the
Style class.
* Test for Style.update with existing Style with _var_data and kwargs
Should retain the _var_data from the original Style instance
* style: Avoid losing VarData in Style.update
If a Style class with _var_data is passed to `Style.update` along with kwargs,
then the _var_data was lost in the double-splat dictionary expansion.
Instead, only apply the kwargs to an existing or new Style instance to retain
_var_data and properly convert values.

* Unit tests for add_style and component styles with foreach

* [REF-2802] Foreach should respect modifications to children
Components are mutable, and there is logic that depends on walking through the
component tree and making modifications to components along the way. These
modifications _must_ be respected by foreach for consistency.
Modifications necessary to fix the bug:
* Change the hash function in `_render` to get a hash over the render_fn's
`__code__` object. This way we get a stable hash without having to call the
render function with bogus values.
* Call the render function once during `create` and save the result as a child
of the Foreach component (tree walks will modify this instance).
* Directly render the original (and possibly modified) child component instead
of calling the render_fn again and creating a new component instance at
render time.
Additional changes because they're nice:
* Deprecate passing `**props` to `rx.foreach`. No one should have been
doing this anyway, because it just does not work in any reasonable way.
* Raise `ForeachVarError` when the iterable type is Any
* Raise `ForeachRenderError` when the render function does not take 1 or 2 args.
* Link to the foreach component docs when either of those errors are hit.
* Change the `iterable` arg in `create` to accept `Var[Iterable] | Iterable`
for better typing support (and remove some type: ignore comments)
* Simplify `_render` and `render` methods -- remove unused and potentially
confusing code.
* Fixup: `to_bytes` requires `byteorder` arg before py3.11
* [REF-2789] Graceful deprecation of rx.input.root and rx.input.input
Handle previously valid code where rx.input.root wrapped
rx.input/rx.input.input and rx.input.slot.
Raise deprecation warnings with hints about how to refactor code.
Copy props from rx.input.root to children inputs and apply any rx.input.slot
components to children inputs in an attempt to keep existing code working as
best as possible.
Fix DebounceInput:
* pass children through (for rx.input.slots)
* pass _rename_props through (for color_scheme)
* Fix for case where `rx.input.root` had event triggers
Fix for case where `rx.input.root` had no input children

fix numerous security vulnerabilities in HTTP parser (closing some request smuggling vectors)
parsing additional requests is no longer attempted past unsupported request framing
on HTTP versions < 1.1 support for chunked transfer is refused (only used in exploits)
requests conflicting configured or passed SCRIPT_NAME now produce a verbose error
Trailer fields are no longer inspected for headers indicating secure scheme
support Python 3.12
** Breaking changes **
minimum version is Python 3.7
the limitations on valid characters in the HTTP method have been bounded to Internet Standards
requests specifying unsupported transfer coding (order) are refused by default (rare)
HTTP methods are no longer casefolded by default (IANA method registry contains none affected)
HTTP methods containing the number sign (#) are no longer accepted by default (rare)
HTTP versions < 1.0 or >= 2.0 are no longer accepted by default (rare, only HTTP/1.1 is supported)
HTTP versions consisting of multiple digits or containing a prefix/suffix are no longer accepted
HTTP header field names Gunicorn cannot safely map to variables are silently dropped, as in other software
HTTP headers with empty field name are refused by default (no legitimate use cases, used in exploits)
requests with both Transfer-Encoding and Content-Length are refused by default (such a message might indicate an attempt to perform request smuggling)
empty transfer codings are no longer permitted (reportedly seen with really old & broken proxies)
** SECURITY **
fix CVE-2024-1135
* Remove TYPE_CHECKING guard for pydantic v1 imports
Retain TYPE_CHECKING guard in v1 fallback to force pyright into pydantic.v1 namespace
* Run unit tests with pydantic v1 now that v2 is installed via poetry
* Allow EventHandler args to be partially applied
When an EventHandler is called with an incomplete set of args it creates a
partial EventSpec. This change allows Component._create_event_chain to apply
remaining args from an args_spec to an existing EventSpec to make it
functional.
Instead of requiring the use of `lambda` functions to pass arguments to an
EventHandler, they can now be passed directly and any remaining args defined in
the event trigger will be applied after those.
* [REF-2273] Implement `.setvar` special EventHandler
All State subclasses will now have a special `setvar` EventHandler which
appears in the autocomplete drop down, passes static analysis, and canbe used
to set State Vars in response to event triggers.
Before:
rx.input(value=State.a, on_change=State.set_a)
After:
rx.input(value=State.a, on_change=State.setvar("a"))
This reduces the "magic" because `setvar` is statically defined on all State
subclasses.
* Catch invalid Var names and types at compile time
* Add test cases for State.setvar
* Use a proper redis-compatible token
* test_foreach: assert on arg _var_type
* [REF-2682] Foreach over dict uses Tuple arg value
When iterating over a Var with _var_type dict, the resulting arg value
_var_type should be Tuple[key, value] so it can be correctly used with other
var operations.
Fix#3157
* Correct _var_type for iteration over Tuple of multiple types
The arg value when iterating over a tuple could be any of the possible values
mentioned in the annotation.
When only one type is used, the Union collapses to the base type, at least in py3.11
* Add comments
* pyi_generator: ignore `app.py` and single files
When running pyi_generator in pre-commit, it passes individual changed files on
the command line as targets, and these were not being properly excluded
according to the EXCLUDED_FILES list.
Add app.py to the EXCLUDED_FILES list so it does not get regenerated
automatically.
* [REF-2587] Ignore top-level theme appearance
From the Radix docs, it is not recommended to actually set `appearance`, but
instead use next-themes to set and switch the appearance dynamically.
Because Reflex already compiles the top-level theme into the next-themes
ThemeProvider, we can blank out the appearance prop after compiling contexts.js
to avoid a mismatch between the selected app appearance and the appearance in
the rx.theme when displaying overlay components.
Fix#2992
* Simplify `run_process_with_fallback` logic
Include log streaming for initial command and fallback command. This is
necessary because if the command produces significant output that is not
consumed, it can fill the OS pipe and block the process from running.
* Avoid overwriting next.config.js when content has not changed
Windows cannot seem to detect when the file changes but the
content is the same and triggers a much longer hot-reload
cycle to deal with the "updated next.config.js"
* Handle case where `next.config.js` doesn't exist yet
