Summary09871: Admin console performs very slowly if no internet connection is available in server
Description

There is an automatic check of last build number in UpdateForm.php (function getUpdateInfo). LimeSurvey tries to connect to ComfortUpdate server if this conditions are satisfied:

1.- php-curl is loaded (see function _performRequest)
2.- buildnumber config param is not empty in config/version.php (see getUpdateInfo). This makes impossible to reproduce the issue in any clone of github repo.

If these conditions are satisfied, and the server has no internet connection (for example no proxy configured) the call to curl_exec (see _performRequest) silently results in a failed connection. Since no timeout is configured, the application gets stuck for a long time.

Steps To Reproduce

1.- Make sure php-curl is installed
2.- Make sure buildnumber is set in version.php
3.- Make sure connecting to internet is impossible (firewall rules, remove proxy configuration, etc)
4.- Enter admin console

Result: Response of LimeSurvey is very slow

Additional Information

I suggest:

  • Disabling ComfortUpdate should be possible from a configuration file and/or GUI to prevent any connection attempt.
  • Curl timeout could be checked or set before curl_exec call
  • If timeout passed, a warning message could be showed
  • Last revision check connecting to ComfortUpdate should not be performed too many times (for example, every time survey list is refreshed)
TagsNo tags attached.
