Description
This is a critical bug for any medium to high traffic eZ publish site.
Transaction Errors occur on concurrent "Send for publish" requests.
Concurrency level: Five requests of "Send for publish" for new objects within a second
Description of the content class of the objects:
Attributes:
Text line
Text line
Text block
Object relations
Object relations
Bug found when an average of 2 of the 5 requests "Send for publish" dies with any of the following eZ Publish transaction fatal errors:
Fatal error: A database transaction in eZ Publish failed.
The current execution was stopped to prevent further problems.
You should contact the System Administrator (test@example.com) of this site.
The current transaction ID is TRANSID-38f8d80170c61a50d3a5686eba385bb9 and has been logged.
Please include the transaction ID and the name of the current script when contacting the system administrator.
With different MySQL errors, here some of them:
Query error: Lock wait timeout exceeded; try restarting transaction.
Query: UPDATE ezcontentobject_tree SET modified_subnode=1250115397 WHERE node_id='1' OR nod e_id='5' OR node_id='12' OR node_id='1071488'
MYSQL ERROR: Lock wait timeout exceeded; try restarting transaction
QUERY ERROR: UPDATE ezcontentbrowserecent SET user_id=9276, node_id=140, created=1250027290, name='Testing' WHERE id='186052'
MYSQL ERROR: Duplicate entry '9572-e4e6f9c7fd1eb1c7b9599e703de183a4' for key 'PRIMARY'
QUERY ERROR: INSERT INTO ezurlalias_ml (id, parent, lang_mask, text, text_md5, action, action_type, link, is_alias, is_original, alias_redirects) VALUES(334975, 9572, 2, 'test1578', 'e4e6f9c7fd1eb1c7b9599e703de183a4', 'eznode:319411', 'eznode', 334975, 0, 1, 1)
MYSQL ERROR: Lock wait timeout exceeded; try restarting transaction
QUERY ERROR: UPDATE ezcontentobject_tree SET modified_subnode=1250028676 WHERE node_id='1' OR node_id='2' OR node_id='141' OR node_id='321006'
Steps to reproduce
1. In an eZPublish 4.1.3 installation create a class with the following attributes:
Text line
Text line
Text block
Object relations
Object relations
2. Create 5 new objects of this class (fill the attributes with some content) using the Administrator interface or an automated import script.
3. Send for publish all objects simultaneously (you can use an automated import script) or have some co-workers send submit two browsers within a second.
4. You will find that some of the "send for publish" requests ends with a transaction fatal error.
