Highlights
Automatically delete state after user has disconnected from the webpage ([7829](https://github.com/gradio-app/gradio/pull/7829) [`6a4bf7a`](https://github.com/gradio-app/gradio/commit/6a4bf7abe29059dbdc6a342e0366fdaa2e4120ee))
Gradio now automatically deletes `gr.State` variables stored in the server's RAM when users close their browser tab.
The deletion will happen 60 minutes after the server detected a disconnect from the user's browser.
If the user connects again in that timeframe, their state will not be deleted.
Additionally, Gradio now includes a `Blocks.unload()` event, allowing you to run arbitrary cleanup functions when users disconnect (this does not have a 60 minute delay).
You can think of the `unload` event as the opposite of the `load` event.
python
with gr.Blocks() as demo:
gr.Markdown(
""" State Cleanup Demo
🖼️ Images are saved in a user-specific directory and deleted when the users closes the page via demo.unload.
""")
with gr.Row():
with gr.Column(scale=1):
with gr.Row():
img = gr.Image(label="Generated Image", height=300, width=300)
with gr.Row():
gen = gr.Button(value="Generate")
with gr.Row():
history = gr.Gallery(label="Previous Generations", height=500, columns=10)
state = gr.State(value=[], delete_callback=lambda v: print("STATE DELETED"))
demo.load(generate_random_img, [state], [img, state, history])
gen.click(generate_random_img, [state], [img, state, history])
demo.unload(delete_directory)
demo.launch(auth=lambda user,pwd: True,
auth_message="Enter any username and password to continue")
