[Sugar-devel] SL Bug #2063

[Mukul Gupta]

With reference to SL Bug # 2063 which deals with bringing some kind of
notification alert whenever an unhandled python exception occurs, I had a
few doubts. There are two approaches that I can think of.

1. Any unhandled python exception is always logged. Thus, if we can check
whenever logging.ERROR has been called, there ,an exception has occured
.Thus if we introduce a flag which attains True value when an exception
occurs, and by checking the value of the flag in a GUI file we can generate
an alert/notification. For this purpose, I have tried to get a git diff of
the sugar.logger .

However, I have a doubt whether it is through this logger.py file through
which logging is taken place . I see the file not being imported by journal
files,etc.

2. Alternatively, if we can make a new file that reads the shell.log line by
line and whenever ERROR: is encountered, an alert is raised. However, for
this the new file has to be active at all times.

It would be great if you could shed some light on what approach should I
follow or suggest an alternative way to this problem.
Waiting for your response and valuable suggestions,
