# HORRIBLE HACK BUT WORKS :-) PR anyone?
|
||||||
|
#
|
||||||
|
# Why?
|
||||||
|
# `browsersteps_playwright_browser_interface.chromium.connect_over_cdp()` will only run once without async()
|
||||||
|
# - this flask app is not async()
|
||||||
|
# - browserless has a single timeout/keepalive which applies to the session made at .connect_over_cdp()
|
||||||
|
#
|
||||||
|
# So it means that we must unfortunately for now just keep a single timer since .connect_over_cdp() was run
|
||||||
|
# and know when that reaches timeout/keepalive :( when that time is up, restart the connection and tell the user
|
||||||
|
# that their time is up, insert another coin. (reload)
|
||||||
|
#
|
||||||
|
# Bigger picture
|
||||||
|
# - It's horrible that we have this click+wait deal, some nice socket.io solution using something similar
|
||||||
|
# to what the browserless debug UI already gives us would be smarter..
|
||||||
|
#
|
||||||
|
# OR
|
||||||
|
# - Some API call that should be hacked into browserless or playwright that we can "/api/bump-keepalive/{session_id}/60"
|
||||||
|
# So we can tell it that we need more time (run this on each action)
|
||||||
|
#
|
||||||
|
# OR
|
||||||
|
# - use multiprocessing to bump this over to its own process and add some transport layer (queue/pipes)
