Bug #55804 [Fbk->Asn]: tempnam(): wrong fallback to /tmp

Edit report at https://bugs.php.net/bug.php?id=55804&edit=1 ID: 55804 User updated by: spam2 at rhsoft dot net Reported by: spam2 at rhsoft dot net Summary: tempnam(): wrong fallback to /tmp -Status: Feedback +Status: Assigned Type: Bug Package: Filesystem function related Operating System: Linux PHP Version: 5.3.8 Assigned To: cmb Block user comment: N Private report: N New Comment: maybe this was fixed in the meantime the whole bugreport was about 1) where php created files below /tmp returned that path and fopen() later failed because open_basedir and so that useless files where lying around but anyways 2) is a bug and not a feature request because $dir is not just a wish to santa claus - falling back to somewhere else is hardly the desired result and unexpected behavior never becomes correct because someone adds it to the docs Previous Comments: ------------------------------------------------------------------------ [2015-04-20 14:45:12] cmb@php.net Actually, during the discussion of this ticket there have been raised three distinct issues: 1) tempnam() doesn't heed open_basedir, when falling back to the temp dir 2) when tempnam() falls back to the temp dir, no notice is thrown 3) it is not well documented under which circumstances tempnam() falls back to the temp dir That is always a bit unfortunate, but even more so in this case, because 1) could be considered a bug, 2) would be a feature/change request, and 3) is a documentation problem. Therefore I have split 2) to bug #69489 and 3) to bug #69488. With regard to 1): I can't reproduce the behavior of the given test script on somewhat recent versions of PHP. I get: Warning: tempnam(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (...) in ... on line 5 Is this issue still reproducable elsewhere? ------------------------------------------------------------------------ [2015-04-18 08:25:51] spam2 at rhsoft dot net boah falling back to /tmp when it is not inide open_basedir() is *plain wrong* because you can not access the created file - it's hard to understand how idiotic the discussions in context of clear bugs are all the time THIS IS NOT A DOCUMENTATION PROBLEM YOU MUST NOT CREATE A FILE UNTOLD OUTSIDE OPEN_BASEDIR THE ONLY EXCEPTION IS SESSION-FILES AND UPLOADTEMP ------------------------------------------------------------------------ [2015-04-18 05:37:35] php at geheimeinformatie dot nl > Even a notice might be considered a BC break. This is arguable at best, but I'm sure the PHP team have thought this through more often than I have. So we can either wait for 7.1 or just roll our eyes, sigh deeply, and deal with it? Righty-oh. ------------------------------------------------------------------------ [2015-04-18 00:35:07] cmb@php.net > I *get* falling back to sensible defaults, but is a simple > warning too much to ask? Even a notice might be considered a BC break. > And the fallback behavios should vanish in PHP7 I'm afraid this ship has sailed[1]. I'm switching the issue to "Documentation Problem".
