Tom决定给他的工程添加一个 README 文件,于是他创建了这个文件并在其中添加了 TODO 列表。添加完成之后,该文件的存放处位于 revision 6.
[tom@CentOS trunk]$ cat README /* TODO: Add contents in README file */ [tom@CentOS trunk]$ svn status ? README [tom@CentOS trunk]$ svn add README A README [tom@CentOS trunk]$ svn commit -m "Added README file. Will update it's content in future." Adding trunk/README Transmitting file data . Committed revision 6.
Jerry 检出了位于 revision 6 最后的代码,并且他直接立刻开始了工作。几个小时以后,Tom 更新了 README 文件并且提交了他所修改的地方。修改的 README 将会看上去像这个样子。
[tom@CentOS trunk]$ cat README * Supported operations: 1) Accept input 2) Display array elements [tom@CentOS trunk]$ svn status M README [tom@CentOS trunk]$ svn commit -m "Added supported operation in README" Sending trunk/README Transmitting file data . Committed revision 7.
现在,仓库位于修改版本 7,并且 Jerry 的工作副本已经过期。Jerry 也更新 README 文件并且试图提交他的更改。
Jerry 的 README 文件将会看上去像这个样子:
[jerry@CentOS trunk]$ cat README * File list 1) array.c Implementation of array operation. 2) README Instructions for user. [jerry@CentOS trunk]$ svn status M README [jerry@CentOS trunk]$ svn commit -m "Updated README" Sending trunk/README svn: Commit failed (details follow): svn: File or directory 'README' is out of date; try updating svn: resource out of date; try updating
Subversion 已经检测出 README 自上次更新后文件已经更改。所以,Jerry 必须更新他的工作副本。
[jerry@CentOS trunk]$ svn up Conflict discovered in 'README'. Select: (p) postpone, (df) diff-full, (e) edit, (mc) mine-conflict, (tc) theirs-conflict, (s) show all options:
Subversion 提示说有一个冲突在 README 文件,并且 Subversion 并不知道如何解决这个问题。于是 Jerry 选择 df选项来检查冲突。
[jerry@CentOS trunk]$ svn up Conflict discovered in 'README'. Select: (p) postpone, (df) diff-full, (e) edit, (mc) mine-conflict, (tc) theirs-conflict, (s) show all options: df --- .svn/text-base/README.svn-base Sat Aug 24 18:07:13 2013 +++ .svn/tmp/README.tmp Sat Aug 24 18:13:03 2013 @@ -1 +1,11 @@ -/* TODO: Add contents in README file */ +<<<<<<< .mine +* File list + +1) array.c Implementation of array operation. +2) README Instructions for user. +======= +* Supported operations: + +1) Accept input +2) Display array elements +>>>>>>> .r7 Select: (p) postpone, (df) diff-full, (e) edit, (r) resolved, (mc) mine-conflict, (tc) theirs-conflict, (s) show all options:
接下来 Jerry 用 postpone(p) 来解决冲突。
Select: (p) postpone, (df) diff-full, (e) edit, (r) resolved, (mc) mine-conflict, (tc) theirs-conflict, (s) show all options: p C README Updated to revision 7. Summary of conflicts: Text conflicts: 1
在用文档编辑器打开 README 文件后,Jerry 意识到 Subversion 已经包含了 Tom 的代码和他的代码,并被冲突标示包裹了起来。
[jerry@CentOS trunk]$ cat README <<<<<<< .min * File list 1) array.c Implementation of array operation. 2) README Instructions for user. ======= * Supported operations: 1) Accept input 2) Display array elements >>>>>>> .r7
Jerry 想让 Tom 的更改跟他的保持一致,所以他决定移除包含冲突标识的行。
所以,更改后的 README 将会是这个样子。
[jerry@CentOS trunk]$ cat README * File list 1) array.c Implementation of array operation. 2) README Instructions for user. * Supported operations: 1) Accept input 2) Display array elements
Jerry 解决了冲突并试图再次提交。
[jerry@CentOS trunk]$ svn commit -m "Updated README" svn: Commit failed (details follow): svn: Aborting commit: '/home/jerry/project_repo/trunk/README' remains in conflict [jerry@CentOS trunk]$ svn status ? README.r6 ? README.r7 ? README.mine C README
在上面的提交中,字母 C 指示说有一个冲突在 README 文件。Jerry 解决了冲突但并没有告诉 Subversion 已经解决了冲突。 他使用了 resolve 命令通知 Subversion 冲突的解决。
[jerry@CentOS trunk]$ svn resolve --accept=working README Resolved conflicted state of 'README' [jerry@CentOS trunk]$ svn status M README [jerry@CentOS trunk]$ svn commit -m "Updated README" Sending trunk/README Transmitting file data . Committed revision 8.
