[e-lang] Mechanics of enhancing Joe-E taming database?

[Adrian Mettler]

Hi Andy and e-lang.
Sorry for taking so long to reply on this.  It slipped off my radar.
I've put a page on the Joe-E wiki regarding the taming database and how 
to customize it.  Please email me if you have any suggestions for 
improving the documentation as it now stands.

To directly answer the questions given:
 > I believe there is some software for each of the following things. 
Is this true, and if so, is there already a way to run such code from 
the command line?  If not, is there already some Java code in the Joe-E 
subversion repository that can do it, and which source file(s) is it in?

one or more .safej files with default deny for every constructor, 
method, and field.

There is commented-out code in the verifier distribution to do this, but 
it's not super convenient.  You can uncomment some lines in 
SafeJImport.java to select a desired package and recompile the plugin.

 > (2) Read a collection of .safej files, and write a Policy.java source 
file.

This is a user-accessible option in the plugin, a per-project preference 
option described in (4) below.

 > (3) Is this correct?  Policy.java files can be compiled to .class 
files, then packaged in a .jar file, then used as a taming database in 
Eclipse.

No.  The Policy class is used only at runtime.

 > If so, I don't see anything in Policy.java source files that contain 
the comments from the .safej files.  Where do the error messages 
reported within Eclipse's use of Joe-E come from, if not from a 
Policy.java file?

 From the safej files.

 > (4) Some code that is invoked from Eclipse, when one enables the 
check box for "Automatically build Policy class" in the project's Joe-E 
properties, that writes a Policy.java file, starting from the taming 
database Joe-E is currently configured to use.

There is code to read the safej files and output a version of Javadoc 
with the safej information.  The output of this tool, as run on the 
distributed safej files is online at
http://www.cs.berkeley.edu/~daw/joe-e/api/

The source code for this doesn't appear to be in the public repository, 
probably because it's based on Sun's code and thus couldn't be released 
under the same license as the rest of the Joe-E distribution.  I should 
be able to get it for you, though, if you want it.
