Bug #16367: No way to get O_EXCL

From: asd@suespammers.org Operating system: Debian GNU/Linux PHP version: 4.1.2 PHP Bug Type: Feature/Change Request Bug description: No way to get O_EXCL I can't find a way to have a script create a file in a directory to be served by Apache without exposing itself to race conditions. I can't use tempnam because that doesn't give me control over the file extension. I can't use file_exits because that will race. I can't use fopen because I can't use O_EXCL|O_CREAT. I can work around this by creating subdirectories, because mkdir fails if the directory already exists. But putting one file per directory is hardly ideal. Having a way to use O_EXCL|O_CREAT --- that is, open a file for writing, creating it, and failing if it already exists all atomicly --- would be a big help. -- Edit bug report at http://bugs.php.net/?id=16367&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=16367&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=16367&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=16367&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=16367&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=16367&r=support Expected behavior: http://bugs.php.net/fix.php?id=16367&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=16367&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=16367&r=submittedtwice
