# Version 2.1.6 # tag::includeManual[] """ CaseCheckTrigger.py This trigger ensures users are not adding new files (directly or by branching) which only differ in case (either filename or a directory element of their path) from existing depot paths. It is useful for both case-sensitive and case-insensitive servers, although most used for the former. Example 1: Typical usage from the Helix Core server triggers table: Triggers: CheckCase change-submit //... "/usr/bin/python3 /p4/common/bin/triggers/CheckCaseTrigger.py %changelist% myuser=%user%" SAMPLE OUTPUT: Submit validation failed -- fix problems then use 'p4 submit -c 1234'. 'CheckCaseTrigger' validation failed: Your submission has been rejected because the following files are inconsistent in their use of case with respect to existing directories: Your file: '//depot/dir/test' existing file/dir: '//depot/DIR' BYPASS LOGIC: By default, this trigger can be bypassed by any user by adding the token BYPASS_CASE_CHECK to the changelist description. Specify 'allowbypass=no' on the command line to disable the ability to bypass this trigger As an exception, if the user is 'git-fusion-user', the case check is always bypassed if 'myuser' is defined. DEPENDENCIES: This trigger requires P4Triggers.py and the P4Python API. SEE ALSO: See 'p4 help triggers'.

CheckCaseTrigger.py v2.1.3: * Added an optional 'allowbypass=no' parameter to enforce the case check policy strictly, disallowing the bypass. * If bypass is allowed, the BYPASS_CASE_CHECK feature is now documented in that it appears in the message users see when the trigger fires, instructing them how to bypass the trigger, but warning of the perils of doing so. * Generally improved the user message when the trigger fires, prescribing next steps for the user, with different options output depending on whether the bypass is enabled. * Changed sample trigger call to avoid calling a random interpreter in the PATH on Linux systems, where the best practice is to use the shebang line in the script. (The Windows sample still illustrates calling an interpreter from the PATH, as that is the best practice on Windows.) * Made some internal coding style consistency tweak (no functional impact). #review-27105 |

#2 | 26681 | Robert Cowham |
Removing Deprecated folder - if people want it they can look at past history! All functions have been replaced with standard functionality such as built in LDAP, or default change type. Documentation added for the contents of Unsupported folder. Changes to scripts/triggers are usually to insert tags for inclusion in ASCII Doctor docs. |
||
#1 | 26652 | Robert Cowham |
This is Tom's change: Introduced new 'Unsupported' directory to clarify that some files in the SDP are not officially supported. These files are samples for illustration, to provide examples, or are deprecated but not yet ready for removal from the package. The Maintenance and many SDP triggers have been moved under here, along with other SDP scripts and triggers. Added comments to p4_vars indicating that it should not be edited directly. Added reference to an optional site_global_vars file that, if it exists, will be sourced to provide global user settings without needing to edit p4_vars. As an exception to the refactoring, the totalusers.py Maintenance script will be moved to indicate that it is supported. Removed settings to support long-sunset P4Web from supported structure. Structure under new .../Unsupported folder is: Samples/bin Sample scripts. Samples/triggers Sample trigger scripts. Samples/triggers/tests Sample trigger script tests. Samples/broker Sample broker filter scripts. Deprecated/triggers Deprecated triggers. To Do in a subsequent change: Make corresponding doc changes. |

#6 | 25715 | Robert Cowham |
Refactor CheckCaseTrigger to work in SDP trigger style - and fix SDP failures. Added modified version of Sven's test harness which works (for Mac at least where some tests must be skipped due to filesystem being case insensitive). |
||
#5 | 24510 | C. Thomas Tyler |
Enhanced CheckCaseTrigger.py so BYPASS_CASE_CHECK override feature works even if the defaultChangeType configurable is set to restricted. |
||
#4 | 24460 | C. Thomas Tyler |
Tweak to case check trigger to allow user to bypass the safety feature by including the token BYPASS_CASE_CHECK in the changelist description. This is likely useful just after initial rollout of the CaseCheckTrigger on an existing server that already contains case inconsistencies. Bypassing the trigger may be required to do some cleanup of existing data. If this trigger is deployed on a new server initially, the bypass may not be needed. |
||
#3 | 21120 | C. Thomas Tyler |
Corrected shebang line in CheckCaseTrigger. Added manual-update version id to replace keyword tag. |
||
#2 | 21098 | C. Thomas Tyler |
SDP-ified: * Changed sample path to reference SDP /p4/common/bin/triggers location. * Changed shebang line to use SDP standard python, which includes P4Python. * Removed the '$Id:' RCS keywordt ag line, as RCS tags aren't allowed in the SDP (since SDP scripts live in many Perforce servers). * Changed file time from text+kx to text+x. * Updated copyright up thru 2016. * One minor cosmetic tweak to doc text. #review-21099 |

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. |
