How to fix curl_exec call hanging when Xdebug is enabled
After following @LazyOne advice I looked at the Xdebug logs more closely and noticed the hanging was occurring after a successful xDebug connection was made. This lead me to two possible causes; some rouge breakpoint that was not getting registered in the PhpStorm Debug tool window or something on the site was delaying the response.
So I did the following:
- Removed all PhpStorm Debug breakpoints in the application and restarted PhpStorm.
- Realized the Automatic Cron setting in Drupal 7 Configuration was set to run every
1 Dayso switched it toNever. My thinking was possibly the execution of Drupal Cron was getting stuck and not completing so every HTTP request was hanging.
It worked and now I wish I had tested each of these steps separately because I don't know which one exactly was the solution. I am leaning towards #1 because when I switched off debugging in PhpStorm the Behat test would execute with no delay. Either way, if you have a similar issue try both of the above.
