WooCommerce crash

[adamziel]

Navigating to https://playground.wordpress.net/?php=8.0&wp=6.4&storage=none&networking=yes&networking=yes&php-extension-bundle=kitchen-sink&networking=yes&plugin=pagbank-connect&plugin=woocommerce&plugin=woocommerce-extra-checkout-fields-for-brazil and poking around in the admin dashboard for a while causes the following crash:

I don't have the exact reproduction steps. I've been navigating through Woo products, orders, and the "checkout fields" plugin in wp-admin.

Potentially related:

I was still able to trigger the crash even with HPOS disabled.

I built PHP with -g2 -O0 and couldn't reproduce the issue anymore. Weird!

I managed to get some unminified error information:

The woocommerce-extra-checkout-fields-for-brazil lives at https://github.com/claudiosanches/woocommerce-extra-checkout-fields-for-brazil/

[adamziel]

The crash also happens without the woocommerce-extra-checkout-fields-for-brazil plugin.

I couldn't reproduce it on vanilla woocommerce, too, which makes me think it's related to the pagbank-connect plugin. Also noteworthy, post_message_to_js used by the fetch() HTTP transport showed up in a bunch of the stack traces logged around the time of the crash which makes me think the crash occurred when processing a response to some HTTP request.

Here's a different stacktrace I got with vanilla WooCommerce, likely related to an out of memory error:

Uncaught RangeError: Maximum call stack size exceeded

Here's the call cycle:

I see the Pagbank plugin has an issue with the CORS. Meaning that the backend calls doesn’t work when called with fetch/frontend ajax calls. Probably it is related to that matter.

This error was fixed by @bgrgicak in https://github.com/WordPress/wordpress-playground/pull/1104. That being said, I ran into another one:

Before it was triggered, I saw the following debug output:

Perhaps auto-rotating the PHP instance on an Out of memory error would help here.

@adamziel do you have any instructions on how to recreate this?

[adamziel]

@bgrgicak nothing more than what I described in other comments – install those plugins, browse for a prolonged period of time, hope the crash happens.

This is likely a duplicate of https://github.com/WordPress/wordpress-playground/issues/1332, except #1332 has a clear reproduction. I'll close this one.
