The life cycle of a Version Control System is mentioned in this chapter. In later chapters, we will see the Subversion command for each operation.
Create Repository:
The repository is a relevant area in which developers store all their work. Repository not handiest stores files, but also the history approximately adjustments. Which way it continues a records of the changes made within the files.
The 'create' operation is used to create a new repository. Most of the instances this operation is done handiest once. When you create a new repository, your VCS will count on you to say some thing to become aware of it, consisting of where you need it to be created, or what name have to be given to the repository.
Checkout
'Checkout' operation is used to create a working replica from the repository. Working copy is a personal place of work in which developers do their changes, and in a while, put up these adjustments to the repository.
Update
As the call indicates, 'update' operation is used to replace working reproduction. This operation synchronizes the working copy with the repository. As repository is shared through all of the groups other builders can devote their changes and your working copy becomes older.
Let us suppose Tom and Jerry are the two builders working on a mission. Both test out the present day model from the repository and begin running. At this point, their operating copies are absolutely synchronized with the repository. Jerry completes his paintings very successfully and commits his modifications to the repository.
Now Tom's working reproduction is obsolete. Update operation will pull Jerry’s ultra-modern changes from the repository and could replace Tom's working reproduction.
Perform Changes
After the checkout, you possibly can do numerous operations to perform adjustments. Edit is the most commonplace operation. One can edit the prevailing document to feature/remove contents from the file.
One can add files/directories. But right now those documents/directories do not grow to be part of the repository, as an alternative they're added to the pending trade-listing and emerge as part of the repository after the dedicate operation.
Similarly you'll delete documents/directories. Delete operation straight away deletes report from the operating reproduction, however actual deletion of the report is delivered to the pending change-listing and changes are made to the repository after the devote operation.
'Rename' operation modifications the name of the file/directory. 'Move' operation is used to move documents/directories from one region to another in a repository tree.
Review Changes
When you take a look at out the operating copy or update the running replica, then your running copy is absolutely synchronized with the repository. But as you do adjustments for your operating reproduction, it will become more recent than the repository. And it is a superb practice to check your modifications before the 'dedicate' operation.
'Status' operation lists the modifications which have been made to the running reproduction. As we've got cited earlier than, every time you do adjustments within the running replica some of these modifications turn out to be a part of the pending trade-listing. And the 'reputation' operation is used to see the pending alternate-list.
'Status' operation handiest affords a listing of changes but no longer the details about them. One can use diff operation to view the info of the changes that have been made to the operating reproduction.
Fix Mistakes
Let us suppose one has made modifications to his operating copy, however now, he desires to throw away these changes. In this situation, 'revert' operation will help.
Revert operation reverts the adjustments which have been made to the running replica. It is viable to revert one or extra documents/directories. Also it is viable to revert the complete running replica. In this example, the 'revert' operation will smash the pending change-list and could carry the working replica returned to its unique state.
Resolve Conflicts:
Conflicts can arise on the time of merging. 'Merge' operation automatically handles the entirety that may be executed adequately. Everything else is taken into consideration as warfare. For example, "hi there.C" record became modified in department and deleted in some other branch. Such a situation requires someone to make the choice. The 'solve' operation is used to assist the user parent out matters and to tell VCS about the ways of handling the conflicts.
Commit Changes
'Commit' operation is used to apply changes from the running reproduction to the repository. This operation modifies the repository and different builders can see these changes with the aid of updating their working reproduction.
Before dedicate, one has to add documents/directories to the pending trade-listing. This is the location in which modifications wait to be committed. With devote, we typically offer a log message to provide an explanation for why a person made adjustments. This log message becomes a part of the history of the repository. Commit is an atomic operation, which means both the complete commit succeeds or it's far rolled returned. Users never see half of-finished devote.
