Broken Mercurial Repo

Question

我在我的根目錄下做了一個revursive sed，當我嘗試提交或者對hg和help進行任何操作時，我得到一個堆棧跟蹤。我錯誤地認爲當我執行sed時，.hg目錄被寫保護。

回購是我的機器本地。

有什麼辦法讓我恢復我的更新日誌或提交評論？我在.hg目錄中找到一個名爲00changelog.i的文件，但它是一個不執行的二進制文件。

的sed命令：

find . -type f -exec sed -i.bak "s/sim-config.h/config.h/g" {} \; 
find . -type f -exec sed -i.bak "s/av-config.h/config.h/g" {} \; 

堆棧跟蹤：

如果沒有上游源代碼，您可以用替換.hg克隆，它可能會取決於如何嚴重打亂了這些文件是。但是，正如您注意到的那樣，Mercurial以二進制格式在內部存儲文件，這將使手工難以修復。

大概你沒有運行sed -i.bak來做一個備份（這會使恢復變得很容易）。

你可以這樣做：

find .hg -mmin -60 -print 

看過去（比如說）60分鐘進行了修改哪些文件。也許沒有太多的修改，你可以找到一些方法來改變sed命令對該文件的影響（但是如果你運行諸如/foo/d之類的東西，這將是不可能的）。
