Subject [jira] Commented: (WW-3546) Add ability to control devMode per request
Date Thu, 16 Dec 2010 17:29:01 GMT


John Lindal commented on WW-3546:

I don't think Struts should implement the method for setting the flag.  The signed cookie
that I'm using is actually generated by a corp-wide login service.  I just use a corp library
to check that it's valid.

I was only suggesting that Struts could provide the flag, so if it is set, it modifies (some
uses of) devMode for that request.

 It makes it easier to track down problems reported in production that are hard to reproduce
in a development environment.
> The places that I have found where it would be useful to control devMode are:  Dispatcher.sendError(),
JSONInterceptor, and DebuggingInterceptor.  (Other uses of devMode are related to logging
and config reloading, and that shouldn't be adjustable.)
> I've currently patched my copy of Struts 2.2.1 so each of the the above-mentioned code
chunks checks an extra, static ThreadLocal variable that I added (in addition to the devMode
member variable).
> 1)  Is this the best solution?
> 2)  Is this something that should be merged into the Struts 2 distribution?
