Dynamic variable $USER gets double-quoted on Trac+MySQL

[xurizaemon]

The default reports contain references to dynamic variable $USER with queries like (report 6)

SELECT p.value AS __color__,
   t.milestone AS __group__,
   (CASE status 
      WHEN 'closed' THEN 'color: #777; background: #ddd; border-color: #ccc;'
      ELSE 
        (CASE owner WHEN '$USER' THEN 'font-weight: bold' END)
    END) AS __style__,
   id AS ticket, summary, component, status, 
   resolution,version, t.type AS type, priority, owner,
   changetime AS modified,
   time AS _time,reporter AS _reporter
  FROM ticket t
  LEFT JOIN enum p ON p.name = t.priority AND p.type = 'priority'
  ORDER BY (milestone IS NULL), milestone DESC, (status = 'closed'), 
        (CASE status WHEN 'closed' THEN modified ELSE (-1)*p.value END) DESC

This throws the error, Report execution failed: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 'kris', ')' THEN 'font-weight: bold' END)\r\n END) AS style,\r\n id AS tic' at line 6")

By replacing '$USER' with $USER in the report query, the error disappears and the report works fine. It appears that this combination of Trac+Python+MySQL quotes the dynamic variables, leading to errors when the original queries using the extra quote are used.

• Python 2.5.1c1 (release25-maint, Apr 12 2007, 21:00:25) [GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
• MySQL 5.0.38-Ubuntu_0ubuntu1-log Ubuntu 7.04 distribution
• Trac 0.10.3-1
• Ubuntu Feisty

(Apologies if this is a dupe, I did search and didn't find anything matching $USER and MySQL.)
