clearcase

问题 I\'ve recently used git svn and enjoyed it very much. Now I\'m starting a new project at a different customer. At that site the SCM of choice is ClearCase. I haven\'t found a baked equivalent of git svn for ClearCase. Is there anybody who has tried to use git locally as a front-end to ClearCase using some tricks, configuration or scripting with any measure of success? If so can you please explain the method used? 回答1: Here's a method that avoids hijacks, which our team used this method quite

问题 In a static view, how can I view an old version of a file? Given an empty file (called empty in this example) I can subvert diff to show me the old version: % cleartool diff -ser empty File@@/main/28 This feels like a pretty ugly hack. Have I missed a more basic command? Is there a neater way to do this? (I don\'t want to edit the config spec - that\'s pretty tedious, and I\'m trying to look at a bunch of old versions.) Clarification : I want to send the version of the file to stdout, so I

问题 I have applied full baseline for my release. for ex. Baseline \"MYProj_2.0.0.20\". Then testing team found some major issue. To fix that development team has delivered few changes. After completing the build , I have applied the same baseline again \"MYProj_2.0.0.20. But this time i have applied Incremental baseline. As per UCM, the baseline MYProj_2.0.0.20 was turned as MYProj_2.0.0.20.3452 (some random number at end to made it unique). Now If i consider MYProj_2.0.0.20.3452 as release

问题 Could anyone explain what is a Evil Twin and Subtractive merge in Clearcase? 回答1: Evil Twin An Evil Twin is an element that you have removed (using rmname) and want to re-add, but it's 'evil twin' exists in previous versions of the directory. You have to remember that each element had a unique ID, so you are attempting to add an element with the same name - but with a different UID. This is not allowed. The best way to deal with an Evil Twin is to relink the newest version you can find of the

问题 I would like to set to a clearcase view from a python script, and then execute commands within that view. I have tried using various methods outlined here: subprocess but I have not had any success. Does anyone know how to accomplish this? 回答1: I wouldn't recommend setting a view, because setview itself spawn a new process. I really prefer working with /view/viewTag/aVob/... after starting the view ( cleartool startview viewTag ) The "spawn process" issue makes the all thing too complex in my

问题 I have seen in ClearCase that there is a Snapshot view and a Dynamic view. What are the differences between these types of views (I\'m assuming there are only two types of views) and when are the appropriate times to use them? 回答1: Snapshot views are based on the local filesystem (like a workspace in Subversion): you load files anywhere you want on your hard drive you have to ' cleartool update ' to refresh its content Dynamic views are based on network content: they represent the dynamic (as

问题 What are the core concepts of the Clearcase version control system every developer should know? 回答1: Core concepts? centralized(-replicated) VCS : ClearCase is halfway between the centralized VCS world (one or several "centralized" repos or VOBS - Version Object Bases - every developer must access to commit) and the distributed VCS world. But it also supports a "replicated" mode allowing you to replicate a repo in a distant site (MultiSite ClearCase), sending deltas, and managing ownership.

问题 This piece of Perl is telling me that a file in ClearCase doesn\'t exist when it does; $x = \"PATH/TO/FILE\" if (-e $x) { print \"This file exists on the file system\"; } else { print \"I can\'t see this file\"; } Has anyone seen this before? Some files return fine. Got me stumped. Clearcase view is dynamic, hosted on unix. This piece of code is returning that a file exists and another doesn\'t when they are in the same folder on the same view. 回答1: Clearcase stores its 'files' as directories

问题 I unpacked a zip-file delivery into a clearcase view. Now I want to add the complete file tree to the repository. The GUI only provides an \"Add to source control ...\" for individual files/directories. Do you know how to recursively add the whole tree? (I\'m on a Windows system, but have Cygwin installed.) 回答1: I would rather go with the clearfsimport script, better equipped to import multiple times the same set of files, and automatically: add new files, make new version of existing files
