Description: ------------ hasErrors() method has returned true after invoking pop() method on PEAR 1.4.9. Should pop() method remove the element from $_errorsByLevel property?

The patch that I posted is incorrect, since $_errorsByLevel array is reverse order to $_errors array. The correct patch as follows: --- ErrorStack.php.orig 2006-06-18 19:02:58.687500000 +0900 +++ ErrorStack.php 2006-06-21 17:39:00.605076600 +0900 @@ -673,7 +673,14 @@ */ function pop() { - return @array_shift($this->_errors); + $err = @array_shift($this->_errors); + if (!is_null($err)) { + @array_pop($this->_errorsByLevel[$err['level']]); + if (!count($this->_errorsByLevel[$err['level']])) { + unset($this->_errorsByLevel[$err['level']]); + } + } + return $err; } /**

move to pear, pear_errorstack is not an independent package.

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
