我遇到某个页面上500错误的问题:http://www.artevolution.com/shop/abstract.html?p=9
这是我得到的支持票:
看起来分段错误发生在以下查询中:
SELECT `_default_table`.`entity_id`,
`_default_table`.`entity_type`,
Ifnull(_store_table.code_id, _default_table.code_id)
AS `code_id`,
Ifnull(_store_table.store_id, _default_table.store_id)
AS `store_id`,
Ifnull(_store_table.control_script, _default_table.control_script)
AS
`control_script`,
Ifnull(_store_table.tracking_script, _default_table.tracking_script)
AS
`tracking_script`,
Ifnull(_store_table.conversion_script, _default_table.conversion_script)
AS
`conversion_script`,
Ifnull(_store_table.conversion_page, _default_table.conversion_page)
AS
`conversion_page`,
Ifnull(_store_table.additional_data, _default_table.additional_data)
AS
`additional_data`
FROM `googleoptimizer_code` AS `_default_table`
LEFT JOIN `googleoptimizer_code` AS `_store_table`
ON _store_table.entity_id = _default_table.entity_id
AND _store_table.entity_type = _default_table.entity_type
AND _store_table.store_id = 2
WHERE ( _default_table.entity_id = '' )
AND ( _default_table.entity_type = 'category' )
AND ( _default_table.store_id IN ( 0, '2' ) )
ORDER BY `_default_table`.`store_id` DESC
LIMIT 1;
您希望让开发人员查看生成此查询的内容,以及我提到的其他三个查询(为方便起见,我将在下面再次提供这些查询),看看他们是否可以查明代码中发生了什么(可能导致查询循环)。查询如下:
SELECT `catalog_category_entity`.*
FROM `catalog_category_entity`
WHERE ( entity_id = '' );
SELECT `attr_table`.*
FROM `catalog_category_entity_varchar` AS `attr_table`
WHERE ( attr_table.entity_id = '' )
AND ( attr_table.store_id IN ( 0, '2' ) )
UNION
SELECT `attr_table`.*
FROM `catalog_category_entity_int` AS `attr_table`
WHERE ( attr_table.entity_id = '' )
AND ( attr_table.store_id IN ( 0, '2' ) )
UNION
SELECT `attr_table`.*
FROM `catalog_category_entity_text` AS `attr_table`
WHERE ( attr_table.entity_id = '' )
AND ( attr_table.store_id IN ( 0, '2' ) )
UNION
SELECT `attr_table`.*
FROM `catalog_category_entity_datetime` AS `attr_table`
WHERE ( attr_table.entity_id = '' )
AND ( attr_table.store_id IN ( 0, '2' ) )
ORDER BY `store_id` ASC;
SELECT `_default_table`.`entity_id`,
`_default_table`.`entity_type`,
Ifnull(_store_table.code_id, _default_table.code_id)
AS `code_id`,
Ifnull(_store_table.store_id, _default_table.store_id)
AS `store_id`,
Ifnull(_store_table.control_script, _default_table.control_script)
AS
`control_script`,
Ifnull(_store_table.tracking_script, _default_table.tracking_script)
AS
`tracking_script`,
Ifnull(_store_table.conversion_script, _default_table.conversion_script)
AS
`conversion_script`,
Ifnull(_store_table.conversion_page, _default_table.conversion_page)
AS
`conversion_page`,
Ifnull(_store_table.additional_data, _default_table.additional_data)
AS
`additional_data`
FROM `googleoptimizer_code` AS `_default_table`
LEFT JOIN `googleoptimizer_code` AS `_store_table`
ON _store_table.entity_id = _default_table.entity_id
AND _store_table.entity_type = _default_table.entity_type
AND _store_table.store_id = 2
WHERE ( _default_table.entity_id = '' )
AND ( _default_table.entity_type = 'category' )
AND ( _default_table.store_id IN ( 0, '2' ) )
ORDER BY `_default_table`.`store_id` DESC
LIMIT 1;
我还在服务器的以下位置放置了strace的副本以及来自strace的相关查询: http://deathbecomesher.ca/artevo/segFaultPageLoadQueries.txt http://deathbecomesher.ca/artevo/segFaultPageLoadStrace.txt
有没有人有关于如何解决这个问题的想法?我是一个新的开发人员,不知道如何继续。非常感谢您的阅读。
