Bug #73292 [NEW]: readline_info returns empty/old line_buffer info

From: me at xbug dot de Operating system: Debian PHP version: 5.6.26 Package: Readline related Bug Type: Bug Bug description:readline_info returns empty/old line_buffer info Description: ------------ Under php5.4 (ubuntu 14.04) the function readline_info returned the correct values. But since (possible 5.5) php5.6 (debian jessie) it returns empty and sometimes old values. I've tested it also under php7.0 (Mint) and the behaviour is the same as in php5.6. Test script: --------------- <?php readline_completion_function( function ($input) { $info = readline_info(); $text = substr($info['line_buffer'], 0, $info['end']); var_dump($info); if ($info['point'] !== $info['end']) { return []; } // task name? if (false === strpos($text, ' ') || !$text) { return ['one', 'three']; } // This is never called since php 5.6 $cmd = substr($text, 0, strpos($text, ' ')); if ($cmd === 'one') { return ['two']; } elseif ($cmd === 'three') { return ['four']; } return []; } ); while (true) { readline('cmd: '); } Expected result: ---------------- $ php readline.php cmd: onearray(6) { ["line_buffer"]=> string(3) "one" ["point"]=> int(3) ["end"]=> int(3) ["library_version"]=> string(16) "EditLine wrapper" ["readline_name"]=> string(0) "" ["attempted_completion_over"]=> int(0) } Actual result: -------------- $ php readline.php cmd: onearray(6) { ["line_buffer"]=> string(0) "" ["point"]=> int(3) ["end"]=> int(3) ["library_version"]=> string(16) "EditLine wrapper" ["readline_name"]=> string(0) "" ["attempted_completion_over"]=> int(0) } -- Edit bug report at https://bugs.php.net/bug.php?id=73292&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73292&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73292&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73292&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73292&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73292&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73292&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73292&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73292&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73292&r=support Expected behavior: https://bugs.php.net/fix.php?id=73292&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73292&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73292&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73292&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73292&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73292&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73292&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73292&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73292&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73292&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73292&r=mysqlcfg
