However, once generated, it enabled DSEE to calculate the optimum way to perform a build, re-using all modules that had previously been processed and whose version specifications matched the specifications for the build. Some things that I have done to cope with using CC are: Originally, ClearCase clearcas only full “fat” clients running native on Unix and Windows. So it is “id-accessed” or “id-referenced”. On merge, the system would recognize that lines with the metadata markers do not conflict unless the markers changed clearcasse – it would ignore the metadata content.
Mandate an “always rebase before deliver” policy for child branches to avoid people “breaking the integration stream” when delivering code that conflicts with recent changes.
Introduction to the Rational ClearCase UCM tutorial
Rational ClearCase is a family of computer software tools that supports software configuration management SCM of source code and other software development assets. That means when you compare two commits, you have to compare the list of all files and directories to find the delta, since commits are not atomic across files or directories, meaning there is no single name for all the changes to all the files that make up a logical delta. What I have works for me; it isn’t necessarily for everyone.
Retrieved from ” https: We always considered that practice as evil mixing meta-data information into dataintroducing “merge hell”. When a file is “removed” rmnameit does not know it: Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.
This is a collection of rules stored internally in a text file, but compiled before use that specifies what element versions files or directories are to be displayed in a view.
The networked filesystem provided by MVFS allows for build auditing.
Views dynamic views are fast on our setup. ClearCase also supports snapshot views, which are copies of repository data. Once you understand how that’s done and Clearcase does it very well, to the point where we do even small changes as a branch and re-merge, not something I would have ever done with RCS or CVSyou’ll find your life is made a lot easier.
When starting a new code-base, make sure you get the streams and projects layout right from the start by planning ahead. Then they will merge their checkout version of that same file.
Retrieved July 17, It also supports design-data management of electronic design artifacts, thus enabling hardware and software co-development. Developers typically have one or more views at their disposal.
Partly because I insisted on it, we embedded version control information in the source files via a check-in trigger. A baseline selects one version of every element in a component.
What are the basic clearcase concepts every developer should know? – Stack Overflow
Specifically, this lets you know the label was applied on which branch and which branch is the parent cleearcase to a branch-in-question. Our project migrated later, when there was already some experience with CC. When you check out you lock the file until you check-in it in.
If your checkins take 2 minutes per file, well, you’ve got serious problems with your setup. If there was a system for handling keywords and an appropriate merge manager, then: Although by default checkouts are reserved lockedyou can always unreserve the checkout later, or create the checkout unreserved. One aspect of the reasoning is that key files, such as ‘stderr. As opposed to dynamic views, snapshot views are maintained on a local OS-specific file system and do not require network access.
Commercially, my employer used SCCS up to mid, but they started to switchover to Atria ClearCase from earlytackling separate product sets one at a time. It only affects a singe file, or a single directory without its files ct findmerge is recursive. Under base ClearCase, each view is controlled by its associated configuration specificationcommonly referred to as a config spec. You claercase the sources in your private work area through your development view.

The combination of distant versioned and local private files allows a dynamic view to appears like a classic hard drive whereas actually any file “written” is stored tutorjal the associated view storage. ClearCase dynamic views are slower than local filesystems, even with a good network infrastructure.
