Version Control with Subversion - Login

Basic Usageflict on a file-by-file basis when you run svn update. If you're running an update and don'twant to resolve any conflicts, you can pass the --non-interactive option to svn update,and any file in conflict will be marked with a C automatically.The C stands for conflict. This means that the changes from the server overlapped withyour own, and now you have to manually choose between them after the update has completed.When you postpone a conflict resolution, svn typically does three things to assistyou in noticing and resolving that conflict:• Subversion prints a C during the update and remembers that the file is in a state of conflict.• If Subversion considers the file to be mergeable, it places conflict markers—specialstrings of text that delimit the “sides” of the conflict—into the file to visibly demonstratethe overlapping areas. (Subversion uses the svn:mime-type property to decide whethera file is capable of contextual, line-based merging. See the section called “File ContentType” to learn more.)• For every conflicted file, Subversion places three extra unversioned files in your workingcopy:filename.mineThis is your file as it existed in your working copy before you updated your workingcopy—that is, without conflict markers. This file has only your latest changes in it. (IfSubversion considers the file to be unmergeable, the .mine file isn't created, since itwould be identical to the working file.)filename.rOLDREVThis is the file that was the BASE revision before you updated your working copy. Thatis, the file that you checked out before you made your latest edits.filename.rNEWREVThis is the file that your Subversion client just received from the server when you updatedyour working copy. This file corresponds to the HEAD revision of the repository.Here OLDREV is the revision number of the file in your .svn directory, and NEWREV is therevision number of the repository HEAD.For example, Sally makes changes to the file sandwich.txt, but does not yet committhose changes. Meanwhile, Harry commits changes to that same file. Sally updates herworking copy before committing and she gets a conflict, which she postpones:$ svn updateConflict discovered in 'sandwich.txt'.Select: (p) postpone, (df) diff-full, (e) edit,(h)elp for more options : pC sandwich.txtUpdated to revision 2.$ ls -1sandwich.txtsandwich.txt.minesandwich.txt.r1sandwich.txt.r2At this point, Subversion will not allow Sally to commit the file sandwich.txt until thethree temporary files are removed:$ svn commit -m "Add a few more things"svn: Commit failed (details follow):svn: Aborting commit: '/home/sally/svn-work/sandwich.txt' remains in conflict29
