I've had coffee, and also I've eaten a bit of crow. If I had no
dignity to spare I might have dropped this thread after the last
post, but I owe it to those who might come after me to explain
what happened. If I have any excuse, it is that I wrote this code
when I had about a month of python experience.
So here we go...
The cleanup part is to write a logfile. The logfile is written by
the write() method of a log object. The method was coded to accept
any number of data types and execute based on the type from an
if/elif/else code block. The cgi object was passed to the method.
The original code follows:
## code begins
if type(args) == type({}): ## it's a dictionary
args['time_date_stamp'] = '%s%d' %
(std.local_time(),std.randomize(8))
keys = args.keys()
keys.sort()
for key in keys:
outfile.write('\t%s: %s\n' % (key,args[key]))
elif type(args) == type(''):
outfile.write('%s\n%s\n' % (std.local_time(),args))
elif std.IsCgiObj(args): ## dump the cgi object
dump = args.getEnv('time_date_stamp=%s' %
(std.local_time()))
for line in dump:
outfile.write(' %s\n' % line)
else : ## default = it's a list
if args:
outfile.write('time_date_stamp=%s\n' %
(std.local_time()))
for arg in args:
outfile.write(' %s\n' % arg)
## /code ends
I did two obvious things wrong here:
First of all, std.IsCgiObj() returned false when I changed
the class name because std.IsCgiObj() tested for an explicit
match of 'cgitools' with the objects __class__.__name__ member.
Secondly, and worse, the default of the test block was an assumption
and I did not test the assumption. Bad, bad, very bad!
Therefore my code attempted to process the object as a list and down
the Rabit Hole we went. And I ended up with some *really* big
logfiles :).
Following is a tentative revision:
## code begins
elif 'instance' in (str(type(args))): ## it's an object
if hasattr(args,'getEnv'): ## test for method
dump = args.getEnv('time_date_stamp=%s' %
(std.local_time()))
for line in dump:
outfile.write(' %s\n' % line)
else :
erh.Report("object passed to logger.write()
must have a `getEnv()' method" )
else : ## it's a list
if type(args) != []: ## make no assumptions
erh.Report('List expected in default condition
of logger.write()')
if args:
outfile.write('time_date_stamp=%s\n' %
(std.local_time()))
for arg in args:
outfile.write(' %s\n' % arg)
## /code ends
## erh.Report() writes a messages and aborts process.
Of course, I could have problems with an object with a
malfunctioning getEnv() method, so I'll have to chew that one over
for a while.
I appreciate Terry's help. I'd welcome any other comments. I'm
also researching the use of __class__.__name__. One of my questions
is: can the implementation of an internal like __class__.__name__
change in the future?
