Rational ClearCase – Wikipedia

OK – enough wittering. Big-big thank you for all the edit in my post, by the way. SVN is more like “server-based” protection, where the Apache server can get a first level of protection, but must be completed with hooks to have a finer grain of rights. The Apollo Domain file system allowed special handler programs to intervene during file access. Pages using deprecated image syntax Official website different in Wikidata and Wikipedia. But the basics are much the same – checkout, change, checkin, merge, branch, and so on.

The problem with CC from this viewpoint – clearly, the implementors of CC disagree is that it lacks a system for handling keywords, and therefore also lacks an appropriate merge manager.

So that’s something one should know about ClearCase – most developers are really happy to work with something simple as subversion or git yes, even git is easier to graspAnd even after I knew how to complete the simplest tasks in ClearCase, I had the constant feeling ClearCase works against me, not with me.

Not so in ClearCase. CC does need good administrators – we have them and are fortunate in doing so. Now, in practice, the way open source works, people don’t migrate code around as much as you might think. Learning objectives After completing the lessons in this module you will know understand the concepts and know how to do the following: They can get quite messy for active files tutoriao when you get used to watching them tutorrial becomes a very useful tool and One that is very lacking in other source control tools such as SVN to some extent.

Periodically, the project manager incorporates activities in the shared work area into baselines. I’ve worked on a number of medium to large projects successfully using both Clearcase and SVN. Support for derived objects in a view is similar to DSEE’s concept.

Views dynamic views are fast on our setup. Basically decide if you are going to ‘always branch’ or ‘never branch’. DSEE made use of this feature to invisibly substitute a versioned copy when a particular file was opened. New files and directories created in a ClearCase view are referred as “view-private” to indicate that they are specific to the view and not version-controlled.

But I value what the past has to offer. ClearCase can accommodate large binary files, large numbers of files, and large repository sizes.

Stack Overflow works best with JavaScript enabled. If there was a system for handling keywords and an appropriate merge manager, then: ClearCase is fantastic tool for larger projects interms of developers and size of the project. It supports branching, labeling, and versioning of directories.

That way, the files can be modified over and over, I know where they come from. Create two files with the same size and content, they will get the same id in Git — a SHA1 key — and will be stored only once in the Git repo! A distinguishing feature of ClearCase is the MultiVersion File System MVFSa proprietary networked filesystem which can mount VOBs as a virtual file system through a dynamic viewselecting a consistent set of versions and enabling the production of derived objects.

Instead, a snapshot view stores a copy of the VOB data locally on the user’s computer. The bill-of-materials artifact produced as the result of build auditing is known as the Configuration Record.

The cleafcase from my temporary branches were fully automatic; no-one had changed the files I worked on while I had them checked out. I can half see why; I’m not sure I like giving up that trackability, though. Data synchronization via any protocol can be unidirectional or bidirectional.

Learn to use the merging capabilities of Clearcase or use a tool like Beyond Compare clearvase emacs-diff. If your project is well modularized many small decoupled filesyou will benefit with fewer or no conflicts during merging. ID keywords take two formats, one for files being edited and one for files that are not being edited:.

Getting started with UCM

Why I still think metadata in the file is good I like to have the metadata in the source code because tutoria source code as opposed to my employer’s source code is distributed outside the aegis of the source code control system.

Yes, CC is a complicated system and we’ve had troubles with it, but not since we hired someone that knows it well. I can get away with it because most of my code is not branched. In the UCM management model, config specs do not need to be created or maintained manually: The mergetool is OK; the biggest problem for me is that my server machine is miles or so from my office or homeso that X over that distant is a bit slow but not intolerably so.

The ClearCase problem is the absence of an appropriate merge manager As I’ve indicated in my discussion of SCCS and RCS, if 3-way merging is done treating the keywords in the correct contracted or editable formats, then there is no merge conflict. ID keywords take two formats, one tjtorial files being edited and one for files that are not being edited: Some of the Atria developers had worked on an earlier, similar tuutorial Merging In UCM, the merge operation is an integral part of the deliver operation and can also occur when you rebase your private work area.

They are also internal to the implementation and do not affect the external interface, so I don’t have to make up my mind just yet. We always considered that practice as evil mixing meta-data information into dataintroducing “merge hell”. I’m sure that this little bit of extra work is the reason why it is not supported, something I’ve always felt was shortsighted in such a powerful system.

I am talking about clearttol.

Managing the branch is one of the very important prospect while using version control tool. Tutofial version number starts at 0 just referenced in ClearCase to 1, 2, 3, and so on. I’ve not done enough merging with RCS to be sure what it does with keyword information, c,earcase I note that if it treated both the expanded and ‘contracted’ notations as equivalent regardless of the content of the expanded materialthen merging could take place without conflict, leaving the contracted notation in the output of the merge, which would be appropriately expanded when the resulting file is retrieved after checkin.

So, that’s a moderate summary of why I like to embed the version information in the source files. This page was last edited on 6 Decemberat I haven’t had that problem for a while now I did a systematic renaming in ; that caused some transitional headaches, but Perl scripts allowed me to implement the renaming pretty easily.
