dev/core#3724 - CaseType memory exhaustion

0-intro.md

This is an example extension that simply registers an a case type via hook_managed.

Installation fails as follows:

$ cv en shimmy
Enabling extension "shimmy"
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 69632 bytes) in /Users/totten/bknix/build/dmaster/web/sites/all/modules/civicrm/CRM/Core/Error.php on line 818

Note that is 256mb which should be quite ample for basic administration.

---

Note: This example was actually developed/generated through this process:

• Checkout civicrm/civicrm-core#23961
• Update BunnyDance.mgd.php to enable the definition
• Use mixer to build+execute an example

  civibuild restore dmaster
  ./tools/mixin/bin/mixer test -f --bare /Users/totten/bknix/build/dmaster/web/sites/default/files/civicrm/ext/example-mixin/ mgd-php@1
  

• The same error will appear in the test.
• The generated folder contains an example extension. I copied it to the gist. To make it more readable, I renamed/trimmed some files.
