Bug #71514 [NEW]: Bad dba_replace condition because of Zend MM wrong use

From: aurelien dot dudouit at corp dot ovh dot com Operating system: PHP version: 5.6.17 Package: DBM/DBA related Bug Type: Bug Bug description:Bad dba_replace condition because of Zend MM wrong use Description: ------------ dba_replace fails, ending in 'Could not copy group [x - x] to temporary stream' because of a bad condition. php_stream_copy_to_stream() has been replaced since 5.5 with php_stream_copy_to_stream_ex() without updating the conditions into which it's been enclosed; the newer function returns SUCCESS which is set to 0, hence the following check isn't valid anymore because it's expecting non-zero value (size_t): if (!php_stream_copy_to_stream_ex(...)) { It's been fixed in PHP7.0: if (SUCCESS != php_stream_copy_to_stream_ex(...)) { A patch has already been proposed two years ago, see: http://git.php.net/?p=php-src.git;a=commit;h=9e309a2d10d9696d047ecb442 Test script: --------------- <?php $db = dba_open("foo.inifile", 'c', 'inifile'); dba_insert('foo', 'value1', $db); dba_replace('foo', 'value2', $db); echo dba_fetch('foo', $db); dba_close($db); ?> Expected result: ---------------- All PHP versions >=5.3: value2 Actual result: -------------- PHP5.6 and PHP5.5: value1 -- Edit bug report at https://bugs.php.net/bug.php?id=71514&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71514&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71514&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71514&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71514&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71514&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71514&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71514&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71514&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71514&r=support Expected behavior: https://bugs.php.net/fix.php?id=71514&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71514&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71514&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71514&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71514&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71514&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71514&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71514&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71514&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71514&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71514&r=mysqlcfg
