git跟蹤不適用於不同的本地和遠程名稱？

Question

如果我做

git checkout -b samename origin/samename 

然後跟蹤似乎很好地工作。如果我做後續提交，然後我就可以做

git push 

和git推我提交原產罰款。

但是，如果我這樣做

git checkout -b diffname origin/samename 

然後跟蹤不起作用，儘管親混帳書的這一部分：

$ git checkout -b sf origin/serverfix 
Branch sf set up to track remote branch refs/remotes/origin/serverfix. 
Switched to a new branch "sf" 
Now, your local branch sf will automatically push to and pull from origin/serverfix 

推送操作只是給 「最新的一切」是什麼賦予了？

我在Mac OS上運行git 1.7.1 X

這裏是整個實驗爲那些想嘗試在家裏：

szbwood-mbp15:proj4_local bwood$ vi file1 
szbwood-mbp15:proj4_local bwood$ git add file1 
szbwood-mbp15:proj4_local bwood$ git commit -m"Created file 1" 
[master (root-commit) 5d50289] Created file 1

Everything up-to-date 

奇怪的是，該配置文件看起來很好...

[branch "samename"] 
     remote = origin 
     merge = refs/heads/samename 
[branch "diffname"] 
     remote = origin 
     merge = refs/heads/samename

這不是跟蹤。默認情況下，git push根本不使用跟蹤。它將具有匹配名稱的分支推送到指定的遠程。有一個配置參數來控制此行爲：

push.default

定義動作混帳推應該採取如果沒有的Refspec在命令行上給出，沒有的Refspec在遠程配置中，沒有的Refspec是由命令行給出的任何選項隱含的。可能的值爲：

• 沒有 - 不要推動任何東西。
• 匹配 - 推送所有匹配分支。所有在兩端具有相同名稱的分支都被認爲是匹配的。這是默認設置。
• 跟蹤 - 將當前分支推送到其上游分支。
• 當前 - 將當前分支推送到同名的分支。

同樣，默認是匹配的，所以雖然你必須在你的第一個案例跟蹤設置，它只是匹配的名字，告訴它什麼推動。如果你願意，你當然可以設置push.default到tracking，並獲得你期望的行爲。

至於你從Pro Git的報價...哇，Pro Git通常是一個很好的資源。我還沒有完整閱讀（我傾向於直接閱讀manpages和源代碼），但是我讀過的所有內容都很棒;我很驚訝地發現即使是一個小小的錯誤！
