#50020 [NEW]: DateInterval:createDateFromString() silently fails

From: jennifer dot kimball at nrc dot ca Operating system: Solaris 10 PHP version: 5.3.0 PHP Bug Type: Date/time related Bug description: DateInterval:createDateFromString() silently fails Description: ------------ Documentation of DateInterval:createDateFromString() does not state what happens when the function fails. So far as I can tell, it seems to produce an empty DateInterval object. If an empty object is the expected behaviour then it should be documented. And more importantly, there should be an easy way to test if the object is empty. Given that creating a DatePeriod using an empty DateInterval consumes all the memory available to a session, it seems to me that allowing empty DateIntervals is a design flaw. Reproduce code: --------------- --- From manual page: dateinterval.createfromdatestring#Return Values --- $i=DateInterval::createFromDateString('P1D');//expected to fail $d1=date_create('2009-10-27'); $d2=date_create('2009-11-15'); $p=new DatePeriod($d1,$i,$d2); //PHP times out Expected result: ---------------- expect error at line $i=DateInterval::createFromDateString('P1D') Actual result: -------------- Fatal error: Allowed memory size of 314572800 bytes exhausted (tried to allocate 72 bytes) -- Edit bug report at http://bugs.php.net/?id=50020&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50020&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50020&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50020&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50020&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50020&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50020&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50020&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50020&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50020&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50020&r=support Expected behavior: http://bugs.php.net/fix.php?id=50020&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50020&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50020&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50020&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50020&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50020&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50020&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50020&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50020&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50020&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50020&r=mysqlcfg
