''2003-03-03  (March 03, 2003)''

The wonderful [Metakit] database is a very useful tool, and I use it for many of my projects, including [Tigerbliss].

I would like to use mk (shortform for [Metakit]) in harmony with [cgi.tcl].

I document how to lock the mk db file, so that you don't get multiple processes writing to the same file at the same time -- which will inexorably corrupt your database.

The [Wikit] package contains the locking code that I'm interested in.  I took the acquire and release code from utils.tcl, and the start up code from start.tcl.  Thanks go to [jcw].

I cleaned up the code, and fixed a bug.  

''I'm taking the code off the wiki because this morning it looks like some user-agent munged the code.  Its hairy code and I don't want people getting bad copies of it.''

It will be available at http://rohanpall.com/projects/locktower/

I heartily recommend using Don Libes [cgi.tcl], it works great and tastes yummy too.

04mar03 [jcw] - Thanks for fixing the bug.  It explains why lock-breaking always caused the CGI itself to fail, and the next one to work again.  Change is also in wikit itself now.

Note that [tcllib]'s [ncgi] is based on cgi.tcl, but the code has been
namespaced.

[Ro]: Note that this does not make it better.  Namespacing packages '''usually''' does, but in the case of cgi, where you want to hammer them out quick, the less code, the better.  [cgi.tcl] is tested, time-worn, and made by [Don Libes].
