From: Ben Keene <seraphire@xxxxxxxxx> In preparation for adding new hooks to the submit method of git-p4, restructure the applyCommit function in the P4Submit class. Make the following changes: * Move all the code after the definition of submitted = False into the Try-Finally block. This ensures that any error that occurs will properly recover. This is not necessary with the current code because none of it should throw an exception, however the next set of changes will introduce exceptional code. Existing flow control can remain as defined - the if-block for prepare-p4-only sets the local variable "submitted" to True and exits the function. New early exits, leave submitted set to False so the Finally block will undo changes to the P4 workspace. * Make the small usability change of adding an empty string to the print statements displayed to the user when the prepare-p4-only option is selected. On Windows, the command print() may display a set of parentheses "()" to the user when the print() function is called with no parameters. By supplying an empty string, the intended blank line will print as expected. * Fix a small bug when the submittedTemplate is edited by the user and all content in the file is removed. The existing code will throw an exception if the separateLine is not found in the file. Change this code to test for the separator line using a find() test first and only split on the separator if it is found. * Additionally, add the new behavior that if the changelist file has been completely emptied that the Submit action for this changelist will be aborted.
