note 125163 added to function.clearstatcache

Not documented, but seems like clearstatcache() is clearing the cache only for the process it is being called from. I have 2 PHP scripts running simultaneously, and the first one does call clearstatcache(), but still the second one deadlocks, unless I call clearstatcache() in it too: script1: <?php touch('system.lock'); ... unlink('system.lock'); clearstatcache(); // should be done by unlink? ?> script2: <?php while (is_file('system.lock') { sleep(1); clearstatcache(); // without this, script 2 will deadlock forever! } ?> I also found this page, which leads to the same conclusion: https://stackoverflow.com/questions/9251237/clearstatcache-include-path-sessions ---- Server IP: 45.112.84.4 Probable Submitter: 103.51.167.36 (proxied: 46.10.231.1) ---- Manual Page -- http://php.net/manual/en/function.clearstatcache.php Edit -- https://master.php.net/note/edit/125163 Del: integrated -- https://master.php.net/note/delete/125163/integrated Del: useless -- https://master.php.net/note/delete/125163/useless Del: bad code -- https://master.php.net/note/delete/125163/bad+code Del: spam -- https://master.php.net/note/delete/125163/spam Del: non-english -- https://master.php.net/note/delete/125163/non-english Del: in docs -- https://master.php.net/note/delete/125163/in+docs Del: other reasons-- https://master.php.net/note/delete/125163 Reject -- https://master.php.net/note/reject/125163 Search -- https://master.php.net/manage/user-notes.php
