| Summary: | 0001966: Drupal 5.2 + locale module + Swedish translation => StackOverflowError | ||||
| Description: |
The first request for a Swedish page will render almost ok. I had some issues with unicode characters not displaying correctly. The subsequent requests always cause a StackOverflowError. On the first request for a Swedish node Drupal will read the sv texts from the locale_target table into a PHP associative array which it then serializes and saves to the cache table. Then it will generate the Swedish menu structure and serialize it and save to the cache_menu table. AFAICS the problem is when Drupal on the susequent requests tries to unserialize the previously serialized object from cache_menu. The unserialize fails and Drupal's menu functions loops indefinitely until StackOverflowError is generated. If you have a look in the cache_menu blob you can clearly see that Swedish UTF-8 characters which normally occupy 2 bytes now need 4 bytes. The length field in the serialized strings are incorrect which I guess causes the problem with unserialize. I've tried changing the function db_encode_blob() in includes/database.mysql.inc to return "x'" . bin2hex($data) . "'"; That change combined with settings all encoding properties to ISO8859-1 makes the data in cache_menu become ISO8859-1 encoded. The length fields in the serialized data are however still incorrect. I've tried with all combinations of script-encoding, unicode.runtime_encoding and unicode.output_encoding. Setting all to ISO8859-1 solved the problems I had with the unicode characters not displaying correctly on the first request. But it didn't solve the problem with StackOverflowError. |
