irods_py_rule_pretty_printer

##Instructions:

As irods:

1. Clone this repository

   SOME_DIR=~/github
   mkdir -p ${SOME_DIR}
   cd ${SOME_DIR} ; git clone http://github.com/d-w-moore/irods_py_rule_pretty_printer
   
   

2. As user irods make a symbolic link in /etc/irods to the myinspect module

   ln -s ${SOME_DIR}/irods_py_rule_pretty_printer/myinspect.py /etc/irods
   

3. create a PEP (Policy Enforcement Point) within /etc/irods/core.py ; as an example, prepend following text to that file:

   import myinspect, cStringIO
   import irods_types
   
   def r_of_s (o):
       return repr(str(o))
   
   irods_types_callback = (
   
     [ irods_types.c_string_array, lambda obj: [ r_of_s( i ) for i in obj ]
     ],
   
     [ irods_types.char_array, lambda obj: (r_of_s(obj),)
     ],
     [ irods_types.KeyValPair , lambda obj: [ 'length = (%d)'%obj.len ] + \
                                            [ (str(obj.key[i]),str(obj.value[i]))
                                               for i in range(obj.len) ]
     ],
   )
   
   def pep_api_data_obj_copy_post(rule_args, callback, rei):
       s = cStringIO.StringIO()
       myinspect.myInspect( rule_args, stream = s, types_callback = irods_types_callback )
       callback.writeLine("serverLog","pep_api_data_obj_copy_post")
       callback.writeLine("serverLog","s -> \n\t{}\n".format(s.getvalue()))
   

4. cause the PEP to fire:

imkdir srcDir ; iput ~/VERSION.json srcDir
imkdir dstDir
icp srcDir/VERSION.json dstDir/VERSION.json

Now examine the tail end of the most recent ``~irods/log/rodsLog.XXXX.XX.XX`
