#49531 [NEW]: CURLOPT_INFILESIZE sometimes causes warning "CURLPROTO_FILE cannot be set"

From: gilad at parann dot net Operating system: any (was seen on Win32 XP) PHP version: 5.2.10 PHP Bug Type: cURL related Bug description: CURLOPT_INFILESIZE sometimes causes warning "CURLPROTO_FILE cannot be set" Description: ------------ Set up PHP 5.2.10 with a basedir. Calling curl_setopt ($ch, CURLOPT_INFILESIZE, $len) ; will sometimes cause PHP to generate a warning CURLPROTO_FILE cannot be activated when in safe_mode or an open_basedir is set depending on the exact value of $len !!! Looking at the source code of _php_curl_setopt (from "...ext/curl/interface.c") I think I see why. The code starts with a big switch statement and NO break... So the CURLOPT_INFILESIZE option gets processed by the IF statement that checks if "(Z_LVAL_PP(zvalue) & CURLPROTO_FILE)" !! Sometimes the $len value will happen to have the same bits set as CURLPROTO_FILE and boom - you get the error. Anyway if you avoid setting INFILESIZE things do work - only sometimes that is not so convenient... Reproduce code: --------------- from _php_curl_setopt in "...ext/curl/interface.c": switch (option) { case CURLOPT_INFILESIZE: /* .... many many more options with NO break! */ case CURLOPT_REDIR_PROTOCOLS: case CURLOPT_PROTOCOLS: convert_to_long_ex(zvalue); if (((PG(open_basedir) && *PG(open_basedir)) || PG(safe_mode)) && (Z_LVAL_PP(zvalue) & CURLPROTO_FILE)) { php_error_docref(NULL TSRMLS_CC, E_WARNING, "CURLPROTO_FILE cannot be activated when in safe_mode or an open_basedir is set"); RETVAL_FALSE; return 1; } error = curl_easy_setopt(ch->cp, option, Z_LVAL_PP(zvalue)); break; Expected result: ---------------- I expect the call to curl_setopt with CURLOPT_INFILESIZE to work Actual result: -------------- A warning is generated CURLPROTO_FILE cannot be activated when in safe_mode or an open_basedir is set -- Edit bug report at http://bugs.php.net/?id=49531&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49531&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49531&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49531&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49531&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49531&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49531&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49531&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49531&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49531&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49531&r=support Expected behavior: http://bugs.php.net/fix.php?id=49531&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49531&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49531&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49531&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49531&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49531&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49531&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49531&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49531&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49531&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49531&r=mysqlcfg
