CrashReporter

CrashReporter creates reports from the traceback if your python code crashes. The reports can be uploaded directly to the developers via email or web server. If no internet connection is available, crash reporter stores offline reports and later sends them when possible.

Features

Features of crashreporter include:

- Uploading of crash reports via email or to a web server (HQ).
- Offline crash reporting that stores crash reports until they are uploaded.
- Traceback and variable inspection output

Installation

To install:

pip install crashreporter

Usage

Implementing the crash reporter is easy. Just create a CrashReporter object. Configure the SMTP or HQ accounts for uploading of reports (optional) and you are good to go!

In the following example, we wil create a Person class that has an optional age attribute. We will then create two Person objects, one with an age and one without. When we attempt to combine their ages we get the following error:

TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'

example.py

    
    from crashreporter import CrashReporter
    
    class Person(object):
    
        def __init__(self, name, age=None):
            self.name = name
            self.age = age
    
    def combine_ages(person_a, person_b):
        a_local_variable = 134
        return person_a.age + person_b.age, Person.__name__
    
    if __name__ == '__main__':
        # Note I have used a configuration file for setting up SMTP and HQ accounts but you can also call functions
        # cr.setup_smtp() and cr.setup_hq() with your credentials to configure SMTP/HQ respectively.
        cr = CrashReporter(report_dir='/home/calvin/crashreporter',
                           check_interval=10,
                           config='./crashreporter.cfg')
    
        cr.application_name = 'My App'
        cr.application_version = '1.1.350'
    
        calvin = Person('calvin', age=25)
        bob = Person('bob')
        combine_ages(calvin, bob)
    
        while 1:
            pass

When the crash occurs, the crash reporter will attempt to send it by email or upload it to the HQ server, if both methods fail, the crash is written to file in report_dir. The next time the script is run, the crash reporter will look for any offline reports and attempt to send them every check_interval seconds. After a sucessful upload, the stored reports are deleted.

Configuration File

If you don't want to keep your SMTP and HQ credentials in your scripts you can alternatively use a configuration file. Simple pass the path to the configuration file as the config argument in CrashReporter or call the load_configuration(path) method with the path. The format of the configuration file should have two sections, SMTP and HQ. Under each section are parameters that are passed to the setup_smtp and setup_ftp functions:

Example:

[SMTP]
user = mycrashreporter@gmail.com
passwd = mypasswordissupersecret
recipients = developer1@gmail.com, developer2@gmail.com
host = smtp.gmail.com
port = 587

[HQ]
api_key = ar923086wkjsldl235dfgdf32
server = http://www.crashreporter-hq.com

Attributes

The CrashReporter has several attributes that can be changed:

offline_report_limit:
        The maximum number of offline reports to save before overwriting
        the oldest report.

application_version:
        Application version as a string to be included in the report.

application_name:
        Application name as a string to be included in the report.

source_code_line_limit:
        The number of source code lines to include before and after the error
        as a tuple (before, after)
