v1.3.0: New API from PIA

v1.3.0: New API from PIA

• Uses a new API endpoint released by PIA
• Only a client id is needed and it is randomly generated. No more config file needed
• The API tends to not return a response or reset connections if you use an unsupported gateway or try to port forward twice unfortunately

v1.2.0: Minor changes

Minor changes

• The response encoding is now read from the encoding header
• The backup if one isn't sent is UTF-8. This can be changed with the DEFAULT_ENCODING variable.
• Debugging statements are printed with a function to make the code a little cleaner

v1.1.0: Big error checking changes

Big error checking changes

• Error handling (printing message, printing exception, exiting with exit code) is now handled by a handleError () instead of repeated code.
• Added a concatStringToList () method to format some messages for handleError () where a list is displayed.
• Fixed logic errors in some error handling blocks (mainly by refactoring to a method)
• Script now checks for missing keys in the credentials file instead of waiting for the API to return an error response (this avoids a crash when --debug tries to print the credentials).
• isConnected () now returns early if the interface doesn't exist. This is faster and avoids a crash when trying to find the IP address for an interface that doesn't exist.
• Added unique exit codes for each error. A small explanation is printed when the application exits as well as them being documented in a comment.
• Some formatting changes.

v1.0.5 Minor Changes

Minor Changes

• Default timeout is now 10 seconds for slow connections (the API call sometimes takes a few seconds
  even on a decent connection anyway).
• isConnected () now checks if the interface exists (this used to be all that was checked) and now if it has at
  least one IPV4 address (is up).
• ValueError exception is caught if the API response is malformed JSON (for some reason).
• Added documentation for constants to README

v1.0.4 Error Checking Changes

Error Checking Changes

• urllib API call now has a try catch block for HTTPError and URLError exceptions.
• getIPAddress () now checks if the VPN interface has more than 1 IPV4 address and exits if so. The address limit is set by the ADDRESS_LIMIT variable in the method.

Refactoring

• netifaces calls separated into multiple lines to be more legible (multiple data structures involved).
• Some code moved outside of try except blocks.
• Switched methods with more than one argument to named parameters.

v1.0.2 Minor Update

Minor update

• Switched to with statement for opening API connection (instead of relying on destructor).
• Added timeout for API call, the default is 6 seconds but can be updated by modifying the TIMEOUT variable.

v1.0.1 Minor Output Changes

Minor output changes

• License, author, title output uses metadata variables
• Script version and version date are displayed
• Changed displayed messages slightly
• Encoding used to decode API response is now displayed by -debug/--debug

v1.0 First Release

First release after development is mostly done. I shouldn't be making any super breaking changes.

Download and run piascript.pyc or download a source code archive to get the non-compiled script as well as the Readme and License.

Improvements made through development

• Credentials are loaded from a JSON file instead of a hardcoded text file.
• Script is written to be portable (no usage of ifconfig or firewall functionality).
• Uses the netifaces library for querying network interfaces.
• Moved to MIT License.
• Updated Readme with better instructions for creating credentials, etc.
• Added debugging print statements (-debug/--debug).
• Improved exception error messages
• Improved response parsing
