[BUG] `hide_all_callbacks` doesn't apply to clientside callbacks

[antonymilne]

FYI @l0uden @CNFeffery

A small issue with the new features in Dash 3.4.0.

#3564 added the argument hide_all_callbacks that would make all callbacks hidden by default. At the same time, #3563 made it possible to hide clientside callbacks with hidden=True.

Unfortunately hide_all_callbacks does not work for clientside callbacks, only serverside ones. I think this should be easy to fix.

@antonymilne Yes, it should be changed to None here instead of False:

@l0uden do you fancy fixing this at the same time as #3578?

[l0uden]

@antonymilne , sure

@l0uden You can use this app as a test demo:

import dash
from dash import html, Input, Output, State


@dash.callback(
    Output("output", "children", allow_duplicate=True),
    Input("button2", "n_clicks"),
    State("output", "children"),
    prevent_initial_call=True,
)
def button2_update_output(n_clicks, children):
    return children + 1


app = dash.Dash(__name__)

app.layout = html.Div(
    [
        html.Div(
            [
                html.Button("Button 1", id="button1"),
                html.Button("Button 2", id="button2"),
                html.Button("Button 3", id="button3"),
                html.Button("Button 4", id="button4"),
            ]
        ),
        html.Div(0, id="output"),
    ],
    style={"padding": 50},
)


@app.callback(
    Output("output", "children"),
    Input("button1", "n_clicks"),
    State("output", "children"),
    prevent_initial_call=True,
)
def button1_update_output(n_clicks, children):
    return children + 1


@dash.callback(
    Output("output", "children", allow_duplicate=True),
    Input("button3", "n_clicks"),
    State("output", "children"),
    prevent_initial_call=True,
    hidden=False,
)
def button3_update_output(n_clicks, children):
    return children + 1


dash.clientside_callback(
    """(n_clicks, children) => (children + 1);""",
    Output("output", "children", allow_duplicate=True),
    Input("button4", "n_clicks"),
    State("output", "children"),
    prevent_initial_call=True,
)

if __name__ == "__main__":
    app.run(debug=True, hide_all_callbacks=True)
