migrating from [Trac 1.0] to [Trac 1.4] TracError: OperationalError: no such column: description

Question

如磁贴中所述，我正在尝试从 Trac 1.0.11 迁移到 1.4.2（使用 SQLite 后端），但在执行“trac-admin [path] upgrade”命令时出现错误。

TracError: OperationalError: no such column: description

我不知道这个描述栏可以在哪里以及它可以与什么相关。请问有人知道发生了什么事吗？注意：我实际上迁移了 2 个工作区，但只有一个失败了；唯一的功能区别是失败的一个使用了 MultipleWorkflowPlugin，而另一个没有。

以下是该问题的日志跟踪：

PS：之前迁移到 1.0.13 版本的数据库存在同样的问题。

感谢您的帮助。

Answer 1

这是我以前从未见过的一些行为，但我认为这是有道理的。

解决方法：

禁用 MultipleWorkflowPlugin
运行 upgrade
启用 MultipleWorkflowPlugin。

在执行 upgrade 时打开环境时加载组件。初始化 MultipleWorkflowPlugin 组件时，它会尝试获取所有枚举，这会执行查询 description 列的 SQL。 description 列在 upgrade 完成之前不存在，因此会产生错误。

编辑：此问题应在最新版本的 MultipleWorkflowPlugin 中得到修复，请参阅 #13943。

Answer 2

插件的源代码已于上周修复。谢谢 https://trac-hacks.org/ticket/13943
