myDEBUG: 3 identical files yesterday

I do not have any documented code changes over the past week other than update the USPS shipping to K5 this morning, I haven't a clue where to start.

Any ideas or suggestions?

I did look at the raw server logs and the timestamp for the 3 logfiles matched (within a 3 minute timeframe) when

UK-ResearchInMotion Blackberry IP 93.186.30.240 was hitting the server 8-10 times per second

[06-Sep-2014 08:50:27 America/Los_Angeles] PHP Warning:  strstr(): Empty needle in /home/chainwea/public_html/includes/functions/functions_lookups.php on line 712

Hmm, that's the following (highlighted) line in /includes/functions/functions_lookups.php:

  function zen_run_normal() {
    $zc_run = false;
    switch (true) {
[B]      case (strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])):[/B]
      // down for maintenance not for ADMIN
        $zc_run = true;
        break;

The PHP warning is that the $_SERVER['REMOTE_ADDR'] portion is null/empty. While it shouldn't be empty, if you've got someone pounding on your site it's quite possible that they've got a mechanism to obfuscate that value. A possible solution for this case would be to change the line to read:

      case (!empty ($_SERVER['REMOTE_ADDR']) && strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])):

The strstr case in the functions_lookups module is the tip of the proverbial iceberg; using the DTK in a v1.5.3 test site's admin to search for $_SESSION['REMOTE_ADDR'] yields 55 matches, most of them similar to the function's usage.

I also had this debug error yesterday.

Just to close the loop, lest people read this down the road and think they need to do the same, this is fixed in v1.6.0, albeit somewhat differently, by making sure the IP is never blank in the first place.

      case (!empty ($_SE RVER['REMOTE_ADDR']) && strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])):

Great! The above solved my problem. Thanks a lot! :) :) :)
