trac ticket的assign to下拉列表中的名单，没有保存在配置文件里头。读一下TracFaq有下面发现：
This will change the Assign To ticket filed into a select box that only contains existing users. However as it says on the TracTickets page, the user must have logged, in at least once, and set their email address.
If you run multiple Trac sites, and have a set of common users across all Trac sites, it gets annoying to have to log into each one and set the email.
So, what is one to do? Well, there are two things that need to be entered into the database: a session record, and an email record.
Table "session" Column | Type | Modifiers ---------------+---------+----------- sid | text | not null authenticated | integer | not null last_visit | integer |
缺省配置下，trac ticket的状态和bugzilla的bug状态不一样，只有new,fixed,invalid,wontfix,duplicate,worksforme这几种。在trac 0.11之后，可以自己定义workflow，只需要将trac.ini的[ticket-workflow]章节修改一下，就可以支持verify状态：
accept = new -> assigned accept.operations = set_owner_to_self accept.permissions = TICKET_MODIFY leave = * -> * leave.default = 1 leave.operations = leave_status reassign = new,assigned,reopened -> new reassign.operations = set_owner reassign.permissions = TICKET_MODIFY reopen = resolved,verified,closed -> reopened reopen.operations = del_resolution reopen.permissions = TICKET_CREATE resolve = new,assigned,reopened -> resolved resolve.operations = set_resolution resolve.permissions = TICKET_MODIFY verify = resolved -> verified verify.permissions = TICKET_MODIFY close = verified -> closed close.permissions = TICKET_MODIFY
