array_key_exists warning when parsing a "DEFAULT FALSE" token

[devnix]

PHP Warning:  array_key_exists(): The first argument should be either a string or an integer in /var/www/html/vendor/phpmyadmin/sql-parser/src/Components/AlterOperation.php on line 286

A dump inside AlterOperation.php gives me the following result:

I don't have any idea if the value attribute should be a boolean in this case, so I'm not starting a PR right now. I don't know if the correct solution would be to cast to string on the array_key_exists itself, or to save the value attribute as a string instead of a boolean...

This still happens in latest PMA 5.0.3:

Warning in ./vendor/phpmyadmin/sql-parser/src/Components/AlterOperation.php#284
array_key_exists(): The first argument should be either a string or an integer

Any idea how this could be fixed?

I added this to a milestone to have a fix as quickly as possible.

Starting to work on this issue.

I'm not sure how to replicate the issue. Any steps to replicate would be appreciated. 😄

Here you go, @shucon, you can reproduce it with the following simple .sql file, stripped down from some of my customer's schema:

DROP TABLE IF EXISTS `searches`;
CREATE TABLE `searches` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `public_name` varchar(120) COLLATE utf8_unicode_ci NOT NULL,
  `group_id` smallint(5) unsigned NOT NULL DEFAULT '0',
  `shortdesc` tinytext COLLATE utf8_unicode_ci,
  `show_separators` tinyint(1) NOT NULL DEFAULT '0',
  `deleted` tinyint(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ;

ALTER TABLE `searches` ADD `admins_only` BOOLEAN NOT NULL DEFAULT FALSE AFTER `show_separators`;

The problem only seems to occur, if we add a DEFAULT FALSE field in an ALTER TABLE statement, not if it is set directly in CREATE TABLE.

On a PMA 5.0.3 / phpmyadmin/sql-parser 5.4.0 import we then get the following warning:

Warning in ./vendor/phpmyadmin/sql-parser/src/Components/AlterOperation.php#284
array_key_exists(): The first argument should be either a string or an integer

Please let me know if you can now reproduce it.

Hello @onlime thanks for a detailed explanation. I was able to reproduce the issue, but not consistently. Can you please verify that the above patch resolves the problem?

Hi @shucon. Great, thanks! I have applied your patch and confirm it to be fully working (tried it with the stripped down .sql above and the full import of the customer with a bunch of such ALTER TABLE statements). Please push it into the next 5.4.x release.

for those who forgot how to download a patch based on a commit on Github, here's you go:
