问题 In database theory, what is the difference between "conflict serializable" and "conflict equivalent"? My textbook has a section on conflict serializable but glosses over conflict equivalence. These are probably both concepts I am familiar with, but I am not familiar with the terminology, so I am looking for an explanation. 回答1: Just two terms to describe one thing in different ways.

Unmerged paths: both modified: foo.py # This I should fix both modified: bar.py # This Jeff Atwood should fix both added: bin/baz.py # This Joel

今天在提交项目文件到本地SVN时提示错误如下: 过期:”global.php“在事务”21-1“, You have to update your working copy first. 运行update更新后再次提交又出现如下错误: svn: Commit failed (details follow): svn: Aborting commit: 'global.php' remains in conflict 查了一下SVN的手册才知道原来是多个版本之间遇到冲突。 此时你需要解决冲突(合并别人的修改)。 举一个例子,Sally修改了sandwich.txt,Harry刚刚改变了他的本地拷贝中的这个文件并且提交到服务器,Sally在提交之前更新它的工作拷贝得到了冲突: $ svn update C sandwich.txt Updated to revision 2. $ ls -1 sandwich.txt sandwich.txt.mine sandwich.txt.r1 sandwich.txt.r2 在这种情况下,Subversion 不 会允许你提交sandwich.txt,直到你的三个临时文件被删掉。 $ svn commit --message "Add a few more things" svn: Commit failed (details follow):
