SVN - 解决冲突
Tom 决定为他们的项目添加一个 README 文件。 因此,他创建了 README 文件并将 TODO 列表添加到其中。 添加后,文件存储库为修订版 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 检出最新版本的代码 6。他立即开始工作。 几个小时后,Tom 更新 README 文件并提交他的更改。 修改后的 README 将如下所示。
[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,存储库处于修订版 7 并且 Jerry 的 工作副本已过时。 Jerry 还会更新 README 文件并尝试提交他的更改。
Jerry 的 README 文件如下所示。
[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commit -m "Updated README" Sending trunk/README svn: Commit failed (details follow): svn: File or directory 'README' is out of date; try updating svn: resource out of date; try updating
第 1 步:查看冲突
Subversion 检测到自上次更新后 README 文件发生了变化。 因此,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 抱怨与 README 文件有冲突,Subversion 不知道如何解决这个问题。 所以 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:
第 2 步:推迟冲突
接下来Jerry选择postpone(p)选项,这样他就可以解决冲突。
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
在文本编辑器中打开 README 后,他意识到 Subversion 包含了 Tom 的 代码和他的带有冲突标记的代码。
[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 想要 Tom 的 和他的一样,所以他只是删除了包含冲突标记的行。
因此,修改后的 README 将如下所示。
[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,他重试了提交。
[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
第 3 步:解决冲突
在上面的提交中,字母C表示README文件有冲突。Jerry 解决了冲突,但没有告诉 Subversion 他已经解决了冲突。 他使用 resolve 命令通知 Subversion 冲突解决。
[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.
