cdp-patches 1.1

Patching CDP (Chrome DevTools Protocol) leaks on OS level. Easy to use with Playwright, Selenium, and other web automation tools.

CDP-Patches v1.1

---

[!CAUTION] The crbug#1477537 causing the Input Leak has been fixed in #6917162. It will probably be implemented in Chrome-Stable v142+.
CoalescedEvents are now also emitted by Input Events. There is no reason to use this package anymore, except for Select Elements (crbug#40943840).

---

Install it from PyPI

pip install cdp-patches

Or for Full Linting

(Includes: playwright, botright, selenium, selenium_driverless)

pip install cdp-patches[automation_linting]

Leak Patches

Input Package

Concept: Input Domain Leaks

Bypass CDP Leaks in Input domains

For an interaction event e, the page coordinates won't ever equal the screen coordinates, unless Chrome is in fullscreen. However, all CDP input commands just set it the same by default (see crbug#1477537).

var is_bot = (e.pageY == e.screenY && e.pageX == e.screenX)
if (is_bot && 1 >= outerHeight - innerHeight){ // fullscreen
    is_bot = false
}

Furthermore, CDP can't dispatch CoalescedEvent's (demo).

As we don't want to patch Chromium itsself, let's just dispatch this event at OS-level!

Usage

from cdp_patches.input import SyncInput

sync_input = SyncInput(pid=pid)
# Or
sync_input = SyncInput(browser=browser)

# Dispatch Inputs
sync_input.click("left", 100, 100)  # Left click at (100, 100)
sync_input.double_click("left", 100, 100)  # Left double-click at (100, 100)
sync_input.down("left", 100, 100)  # Left mouse button down at (100, 100)
sync_input.up("left", 100, 100)  # Left mouse button up at (100, 100)
sync_input.move(100, 100)  # Move mouse to (100, 100)
sync_input.scroll("down", 10)  # Scroll down by 10 lines
sync_input.type("Hello World!")  # Type "Hello World!"

Async Usage

import asyncio

from cdp_patches.input import AsyncInput

async def main():
    async_input = await AsyncInput(pid=pid)
    # Or
    async_input = await AsyncInput(browser=browser)
    
    # Dispatch Inputs
    await async_input.click("left", 100, 100)  # Left click at (100, 100)
    await async_input.double_click("left", 100, 100)  # Left double-click at (100, 100)
    await async_input.down("left", 100, 100)  # Left mouse button down at (100, 100)
    await async_input.up("left", 100, 100)  # Left mouse button up at (100, 100)
    await async_input.move(100, 100)  # Move mouse to (100, 100)
    await async_input.scroll("down", 10)  # Scroll down by 10 lines
    await async_input.type("Hello World!")  # Type "Hello World!"

if __name__ == '__main__':
    asyncio.run(main())

TODO

• Improve mouse movement timings.
• Implement extensive testing.

[!IMPORTANT]
By the nature of OS-level events (which can only impact actionable windows), this package can only be used with headful browsers.

[!WARNING]
Pressing SHIFT or CAPSLOCK manually on Windows affects input.type(text) as well.

[!WARNING]
Because Chrome does not recognize Input Events to specific tabs, these methods can only be used on the active tab. Chrome Tabs do have their own process with a process id (pid), but these can not be controlled using Input Events as they´re just engines.
