Added output to a log file. The default is the send output to p4triggers.log in the P4ROOT directory, this can be overridden with the parameter log=<path> Also, errors now cause the trigger to fail with sensible output first. |

Updated CheckCaseTrigger.py to fix problems with files within directories. The trigger would not detect case problems for files that are located in subdirectories. Unintentional side effect of modifying the dirs list recursively when checking for mismatched directories. The solution was simple: make a copy of the directory list for the file check. |

#1 | 6413 | Sven Erik Knop |
Added some P4Python-based Perforce triggers. P4Triggers.py is the based class for change trigger in Python modelled on Tony Smith's Ruby trigger with the same name. CheckCaseTrigger.py is a trigger that ensures that no-one enters a file or directory with a name only differing by case from an existing file. This trigger is Unicode aware and uses Unicode-comparison of file names, so it can be used on nocase-Unicode based Perforce servers, which cannot catch the difference between, say, "�re" and "�re" at the moment. clienttrigger.py is a simple trigger that modifies the option "normdir" to "rmdir" for new client specs only. It is meant as a template to create more complex default settings like standard views. |
