To understand why Git does not offer some kind of what you are referring to as an “inheritance mechanism” (not involving a commit), you must first understand one of the core concepts of those SCMs (Git vs. ClearCase for instance) ClearCase uses a linear version storage: each version of an element (file or directory) is … Read more
Aternative to writing API or the like is to simply use snapshot views and automatically write files using “Highjack” functionality …then just check’em in later.
@zzz777: Your question was asked in such a ClearCase centric view that it failed to be comprehensible to people who never used ClearCase before. In fact, Git is light years ahead of ClearCase, and it is the commercial SCMs that need to catch up with OSS systems. I have experience with both ClearCase and Git, … Read more
Here’s a method that avoids hijacks, which our team used this method quite successfully for over a year, until we retired ClearCase for Subversion (per company policy, although it is a backwards step for our team – we were basically just using ClearCase as a dumb file system, and virtually working natively in git, but … Read more
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 previously imported (but modified in the source set of files re-imported) remove files already imported but no longer present in the source set of files. … Read more
How to change default diff tools You can specify an external diff tool by modifying the file map, in “c:\program files\rational\ClearCase\lib\mgrs” The WinMerge suggested by Paul actually modifies that file. Each map line has 3 parts: the CC filetype, the CC action, and the application. Find the section in the map file for text_file_delta file … Read more
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 … Read more
You can find a good comparison between ClearCase and Git in my SO answer: “What are the basic ClearCase concepts every developer should know?“, illustrating some major differences (and some shortcomings of ClearCase) File-centric operations The most single important shortcoming of ClearCase is its old “file-centric” approach (as opposed to “repository-centric” like in SVN or … Read more
