* rx.upload must include _var_data from props
str-casting the dropzone arguments removed any VarData they depended on, like
the state context.
update test_upload to include passing a prop from a state var
* Handle large payload delta from upload event handler
Fix update chunk chaining logic; try/catch wasn't catching errors from the
async inner function.
* Unit test updates
* test_client_storage: simulate backend state expiry
* [HOS-333] Send a "reload" message to the frontend after state expiry
1. a state instance expires on the backing store
2. frontend attempts to process an event against the expired token and gets a
fresh instance of the state without router_data set
3. backend sends a "reload" message on the websocket containing the event and
immediately stops processing
4. in response to the "reload" message, frontend sends
[hydrate, update client storage, on_load, <previous_event>]
This allows the frontend and backend to re-syncronize on the state of the app
before continuing to process regular events.
If the event in (2) is a special hydrate event, then it is processed normally
by the middleware and the "reload" logic is skipped since this indicates an
initial load or a browser refresh.
* unit tests working with redis
When an event/event spec is marked as "temporal", it will not be queued unless
the backend is up. This can be used to prevent periodic events (like from
`rx.moment`) from queueing up while the backend is down, and then stampeding
when the backend comes up and the queue is drained. It can be used to avoid
processing many periodic events at once when the app is only expecting to
process such an event every so often.
In some cases, a routing failure can cause the failure to be cached. When the
router has a cached failure, pushing such a route will never call
routeChangeComplete, and thus on_load event will never be fired for that route.
Purposely clearing the error from the router allows the page to properly load
on subsequent attempts without refreshing the app.

All major browser use a "bfcache" to freeze pages when navigating away from the
domain, then they restore the page when going back.
However if the page uses websockets, these get kind of stuck unless you
disconnect them before freezing (and have a mechanism for reconnecting, which
we already do).
Ref: https://web.dev/articles/bfcacheFix#3478
* `rx.color_mode.icon`, `rx.color_mode.button` and `rx.color_mode.switch` should not require a backend`
* remove print statement
* unit tests and precommit fix
* add unit tests
* change logic to check if event handlers actually contain state. Also delay websocket object check in state.js so server side events can get executed for stateless apps
* make sure events are not queued for server side events particularly ones that call queueEvents(clear_local_storage, clear_cookies, remove_local_storage, remove_cookies) when the app is stateless(no ws)
* fix unit tests
* fix broken unit tests in test_app
* modify socket check in processEvent to only return if socket exists and theres any event in the queue that requires state
* Apply suggestions from code review
make queueEvent call async

* test_connection_banner: Improve assertions
* Actually assert on the presence or absense of the connection banner
* Update XPATH selector to find the connection toast
* Add event handling while backend down to verify queue functionality
* Bring backend down while an event is running to ensure queue does not get
blocked (#3404)
* state.js: set event_processing = false when websocket connects
In case an event was pending when the websocket went down, allow further events
to be processed when it comes back up.
Fix#3404
* test_connection_banner: wait for token indicating backend is connected
* test_connection_banner: increase delay time
make the time window longer in which the backend can go down and get stuck in
event_processing=true for better test reliability
* Ensure the redis connection is reset in new backend thread
Redis has an event loop affinity and needs to be attached to the event loop
that the thread is running.
* Reset event_processing on disconnect
* if the socket never comes back up, it still allows client-side events to be
processed
* on_mount events may start running before the socket is up, so resetting the
flag on connect may break event determinism (test_event_chain.py)
* Support replacing route on redirect
Support next/router `.replace` interface to change page without creating a
history entry.
* test_event: include test cases for new "replace" kwarg
* Connection pulser only depends on has_connection_errors
Avoid showing the WiFi error icon when the state is hydrating / navigating
because not being hydrated is not indicative of a connection error in itself.
* Set is_hydrated=False at route onChangeStart
When navigation event starts, set is_hydrated=False on the client side before
any on_load event is dispatched. This avoids a flickering problem where the
client browser navigates and briefly shows content on the page before
processing on_load events associated with the page.
Fix#2885
* Update pyi
* add pulser for connection + adjust condition for connnection_modal
* update style for connection pulser
* rename connectError to connectErrors
* resolve update bug of connectErrors
* fix pulse definition
* rollback pulse definition
* Define WifiOffPulse icon as its own component
Attach the pulse keyframes and imports to the icon itself so that the code gets
properly included in stateful_components.js when it is used.
* limit number of errors in memory

on what substate is requested.
* test_format: fixup broken tests from adding substates of TestState

kthnxbai ❤️
* Move _is_testing_env to reflex.utils.exec.is_testing_env
Reuse the code in app.py
* Break up `BaseState.get_state` and friends into separate methods
* Add test case for pre-fetching cached var dependency
* Move on_load_internal and update_vars_internal to substates
Avoid loading the entire state tree to process these common internal events. If
the state tree is very large, this allow page navigation to occur more quickly.
Pre-fetch substates that contain cached vars, as they may need to be recomputed
if certain vars change.
* Do not copy ROUTER_DATA into all substates.
This is a waste of time and memory, and can be handled via a special case in
__getattribute__
* Track whether State instance _was_touched
Avoid wasting time serializing states that have no modifications
* Do not persist states in `StateManagerRedis.get_state`
Wait until the state is actually modified, and then persist it as part of `set_state`.
Factor out common logic into helper methods for readability and to reduce
duplication of common logic.
To avoid having to recursively call `get_state`, which would require persisting
the instance and then getting it again, some of the initialization logic
regarding parent_state and substates is duplicated when creating a new
instance. This is for performance reasons.
* Remove stray print()
* context.js.jinja2: fix check for empty local storage / cookie vars
* Add comments for onLoadInternalEvent and initialEvents
* nit: typo
* split _get_was_touched into _update_was_touched
Improve clarity in cases where _get_was_touched was being called for its side
effects only.
* Remove extraneous information from incorrect State instantiation error
* Update missing redis exception message
* feat: Synchronizing localStorage between tabs using browser events
* test_client_storage: Test sync'd local storage vars
* update_vars_internal: generic handler to apply var changes to state tree
Apply fully qualified var names to each substate they are associated with. This
allows consistent updates to arbitrary state vars without having to know their
"setter" arguments, in case the user has overwritted the `set_x` name.

* state.js: only `getBackendURL` dynamically when running client side
During server side rendering, `getBackendURL` cannot access the current
