#50024 [NEW]: "basename" chops first character in filename

From: peo at bsdlabs dot com Operating system: FreeBSD PHP version: 5.2.11 PHP Bug Type: Filesystem function related Bug description: "basename" chops first character in filename Description: ------------ The platform is: FreeBSD 7.2-STABLE #0: Thu Oct 15 07:23:17 CEST 2009 - Problem not tied to a specific version of OS or PHP - Vanilla installation of Horde http://www.horde.org - Identical problem present on two servers - Problem started to occur spring 2009 - Low server load - Intermittent - Comes and goes at certain times during the day. Usually, the problem will start around 11:30 CEST or 10:30 CET, last for 24h and then go away for another 24h. And yes, we have looked for causes for this behaviour - Happens regardless of cache configuration in Horde, even without any caching - Happens regardless of cache and session settings in php.ini - The below is an *example* - One more user on the Horde lists have reported same problem with same OS (FreeBSD) Reproduce code: --------------- function factory($driver, $params = array()) { if (is_array($driver)) { $app = $driver[0]; $driver = $driver[1]; } $driver = basename($driver); if (empty($driver) || $driver == 'none') { return new Horde_Cache($params); } if (!empty($app)) { include_once $app . '/lib/Cache/' . $driver . '.php'; } elseif (file_exists(dirname(__FILE__) . '/Cache/' . $driver . '.php')) { include_once dirname(__FILE__) . '/Cache/' . $driver . '.php'; } else { include_once 'Horde/Cache/' . $driver . '.php'; } $class = 'Horde_Cache_' . $driver; if (class_exists($class)) { $cache = new $class($params); } else { $cache = PEAR::raiseError('Class definition of ' . $class . ' not found.'); } return $cache; } Expected result: ---------------- Should return memcache.php in this case, but it could be "none.php" (where the actual output will be "one.php") Actual result: -------------- [21-Oct-2009 07:28:28] after basename d string(8) "memcache" string(7) "emcache" [21-Oct-2009 07:28:28] backtrace NULL string(7) "emcache" #0 Horde_Cache->factory(memcache, Array ([hostspec] => Array ([0] => localhost),[port] => Array ([0] => 11211),[weight] => Array (),[persistent] => ,[compression] => ,[large_items] => 1,[enabled] => 1)) called at [/usr/local/www/horde/lib/Horde/Cache.php:234] #1 Horde_Cache->singleton(memcache, Array ([hostspec] => Array ([0] => localhost),[port] => Array ([0] => 11211),[weight] => Array (),[persistent] => ,[compression] => ,[large_items] => 1,[enabled] => 1)) called at [/usr/local/www/horde/lib/Horde/Perms/sql.php:57] #2 Perms_sql->Perms_sql(Array ([username] => horde,[password] => <password>,[protocol] => unix,[database] => horde,[charset] => iso-8859-1,[splitread] => ,[ssl] => ,[phptype] => mysqli)) called at [/usr/local/www/horde/lib/Horde/Perms.php:462] #3 Perms->factory(sql, Array ([username] => horde,[password] => <password>,[protocol] => unix,[database] => horde,[charset] => iso-8859-1,[splitread] => ,[ssl] => ,[phptype] => mysqli)) called at [/usr/local/www/horde/lib/Horde/Perms.php:496] #4 Perms->singleton() called at [/usr/local/www/horde/lib/Horde/Registry.php:278] #5 Registry->Registry(0) called at [/usr/local/www/horde/lib/Horde/Registry.php:139] #6 Registry::singleton() called at [/usr/local/www/horde/imp/lib/base.php:49] #7 require_once(/usr/local/www/horde/imp/lib/base.php) called at [/usr/local/www/horde/imp/redirect.php:89] #8 require(/usr/local/www/horde/imp/redirect.php) called at [/usr/local/www/horde/imp/index.php:26] NULL [21-Oct-2009 07:28:28] PHP Warning: include_once(Horde/Cache/emcache.php) [<a href='function.include-once'>function.include-once</a>]: failed to open stream: No such file or directory in /usr/local/www/horde/lib/Horde/Cache.php on line 194 [21-Oct-2009 07:28:28] PHP Warning: include_once() [<a href='function.include'>function.include</a>]: Failed opening 'Horde/Cache/emcache.php' for inclusion (include_path='/usr/local/www/horde/lib:.:/usr/local/share/pear') in /usr/local/www/horde/lib/Horde/Cache.php on line 194 [21-Oct-2009 07:28:39] after basename d string(8) "memcache" string(7) "emcache" -- Edit bug report at http://bugs.php.net/?id=50024&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50024&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50024&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50024&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50024&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50024&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50024&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50024&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50024&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50024&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50024&r=support Expected behavior: http://bugs.php.net/fix.php?id=50024&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50024&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50024&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50024&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50024&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50024&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50024&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50024&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50024&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50024&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50024&r=mysqlcfg
