The MRE can be even further simplified. Recomposition and dynamic structure is irrelevant. The issue pops up the more eagerly the more controls are on the modal screen. The last crash occurred with just two o-ESC sequences.

For what it's worth, after pulling the latest changes on my fork of Textual, I can't reproduce the issue using the simplified MRE in #4668 (comment) when mashing the o and Esc keys.

arcivanov avatar arcivanov commented on July 30, 2024 1

Yep, I removed the textual completely, installed it from the tree and can no longer bang out any of the problem.

Thank you for your issue. Give us a little time to review it.

Another crash looking like it's related (same concurrency issue):

TomJGooding avatar TomJGooding commented on July 30, 2024

Could you provide an MRE or steps to reproduce?

I've just tried rapidly opening and closing the Select using the simple app below and can't reproduce the crash on the latest Textual v0.70.0.

from textual.app import App, ComposeResult
from textual.widgets import Select

LINES = """I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.""".splitlines()


class SelectApp(App):

    def compose(self) -> ComposeResult:
        yield Select((line, line) for line in LINES)


if __name__ == "__main__":
    app = SelectApp()
    app.run()

arcivanov avatar arcivanov commented on July 30, 2024

It's a tough one, unfortunately. It's a proprietary app with a complex dialog with Select and Input components populated by network calls via workers.

But the structure is as follows and 'o' followed by 'escape' cycling really really fast produced the above two exceptions. Meanwhile TradeDialog was dynamically filling in the various fields via async workers while being dismissed, is my guess.

class TradeDialog(ModalScreen):
    BINDINGS = [("escape", "dismiss", "Cancel")]  
    ...


class DialogApp(App):
    BINDINGS = [("o", "new_order", "New Order")]
    
    ...

    @work(exclusive=True, group="DialogApp.action_new_order")
    async def action_new_order(self) -> None:
        await self.push_screen_wait(TradeDialog())

I will need an MRE for this. It could very well be a concurrency issue, but without a place to start I couldn't say what the problem is.

When you say stress testing, are you hammering keys or doing anything automated?

willmcgugan avatar willmcgugan commented on July 30, 2024

Can you reproduce it with this? Or modify this code until it does reproduce the issue?

from textual.app import App, ComposeResult

from textual.widgets import Label, Select, Footer
from textual import work

class StressScreen(ModalScreen):
    BINDINGS = [Binding("escape", "dismiss", "dismiss", priority=True)]

    def compose(self) -> ComposeResult:
        yield Label("foo")
        yield Select([("Hello", "hello"), ("World", "world")])
        yield Select([("Foo", "foo"), ("bar", "bar")])
        yield Footer()


class StressApp(App):
    BINDINGS = [Binding("space", "modal", "modal")]

    def compose(self) -> ComposeResult:
        yield Label("BAR")
        # yield Select([("Foo", "foo"), ("bar", "bar")])
        yield Footer()

I understand that you need an MRE and I'm trying to see if I can provide that for you.

Yes, it was just finger testing, I bumped into the problem ensuring responsive population of the dialog which resulted in me bumping into that error.

Two more separate failures doing the same thing. These seem all to be focused on there not being a SelectOverlay.

One (also causing a shutdown deadlock):

I've added a debug log (non-reordering) to the MessagePump._dispatch_message as follows:

        with self.prevent(*message._prevent):
            logger.debug(f"{self=!r}, {message=!r}, {message.time=!r}, {message._sender=!r}")

I've grepped the resulting logs as follows.
The curious extract is here. I marked the Select.compose and Select.mount with **** between which you can see SelectOverlay being unmounted by the message from the App, marked with ^^^^.

The @nnnnnn are object IDs to help tracking individual objects.

Please stop just spamming tracebacks and logs from your proprietary app.

You say that you understand that this needs an MRE, but I'll try explaining this more bluntly. Without any way to reproduce the issue you're describing, this is impossible to debug. You can't expect anyone to understand exactly what your code is doing only based on the tracebacks or logs.

I had no idea this even involved a ModalScreen from your original issue post.

I have the MRE. The culprit is the number of controls being composed. With just 2 controls the crash is not reproducible. As the number of composed controls grows (i.e. range(20)) the problems becomes increasingly easy to reproduce.
The core failure is unfortunately obscured by a shutdown deadlock so a logging system has to be used to capture the failure (I overwrote the _handle_exception to log it).

I've installed the main branch and the problem still persists @willmcgugan

With what? Your last MRE?

I can no longer reproduce it in main.

Could you paste the output of the following command:

textual diagnose

from textual.

arcivanov avatar arcivanov commented on July 30, 2024

So there were two crashes in this bug:

textual.widget.MountError: Can't mount widget(s) before StressScreen() is mounted

and

textual.css.query.NoMatches: No nodes match <DOMQuery query='SelectOverlay'> on Select(id='class_value')

The MRE reproduced the first one, but I never got to the second one because the MountError was blocking.

Now the second one is still there even though the MRE doesn't crash anymore.

Let me see if I can modify the MRE to reproduce the second one.

Nope, the original problem is still there:

Curiously, I'm unable to trigger the case via a pilot, but fairly reliably can trigger it with my fingers. Also, headed pilot seems rather slow in comparison to what I can do by hand.

import asyncio
import sys

from textual import work
from textual.app import App, ComposeResult
from textual.binding import Binding
from textual.screen import ModalScreen
from textual.widgets import Label, Select, Footer

exc: Exception | None = None


class StressScreen(ModalScreen):
    BINDINGS = [Binding("escape", "dismiss", "dismiss")]

    def compose(self) -> ComposeResult:
        for idx in range(40):
            yield Select([(f"Foo{idx}", f"foo{idx}"), (f"Bar{idx}", f"bar{idx}")],
                         id=f"independent{idx}_value",
                         value=Select.BLANK)


class StressApp(App):
    BINDINGS = [Binding("o", "modal", "modal")]

    def compose(self) -> ComposeResult:
        yield Label("BAR")
        yield Footer()

    @work(exclusive=True)
    async def action_modal(self) -> None:
        await self.push_screen_wait(StressScreen())

    def _handle_exception(self, error: Exception) -> None:
        global exc
        exc = error
        super()._handle_exception(error)


if __name__ == "__main__":

    async def test():
        app = StressApp()
        try:
            async with app.run_test(headless=False, size=None) as pilot:
                while True:
                    await pilot.press("o")
                    await pilot.press("escape")
                    await asyncio.sleep(0)
        finally:
            if exc:
                sys.excepthook(type(exc), exc, None)


    asyncio.run(test())

The pilot waits for messages to be processed, unlike manual keypresses.

From your recent traceback I can tell you are not running the latest Textual. Please check you have installed Textual main in to the same venv.

from textual.

arcivanov avatar arcivanov commented on July 30, 2024

Ok I will recheck. What's the standard way of installing the "latest" textual if not via pip install -U git+https://github.com/Textualize/textual ?

from textual.

willmcgugan avatar willmcgugan commented on July 30, 2024

That should work if you have the venv activated. You could also clone it and run pip install -e .

If pip is installed globally, you can use this to ensure it uses the same env as the python command.

python -m pip
