Hi, I found git sometimes can't detect working trees changes. But I can only reproduce this problem on several specific files, unfortunately these files are copyrighted source files so I can't send them to you. Is there anything I can do to narrow the problem and finally reproduce the bug without these commercial files? I posted a question on stackoverflow which shows the process. http://stackoverflow.com/questions/22684163/cant-reproduce-a-bug-in-git-without-a-specific-file Actually what I'm doing is: git init " copy the first version of file into the working tree. git add . git commit -m 'init' " copy and replace the file into working tree. git status and nothing is reported by git. these two files have the same timestamp, the same size, bug slightly different contents. These files were generated by `git difftool -d` I just manually copied them out from the temp directory just for future review. Git I'm using is msysgit 1.9.0 on windows 7 Best regards, Sheng Yun -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
