How do I know my git repository is same as my Mercurial repository?

Question

I converted my Mercurial repository(in Bitbucket) to git (gitLab), I am wondering that how can I know that no files/comments were missing? How to check if two repositories are the same?

Thanks, Jennifer.

Answer 1

You cannot compare SHA1 hashes between Git and Mercurial (they would be different anyway)

But you can at least script and compare:

• the list of revision in Hg (with their comment)
• git log (which includes comment)

And see if the list has the same number of elements and if the comments matches

For each commit, you can:

• list the files in a given Hg revision (hg status --change <rev>)
• list the files a commit

And make sure each one:

• has the same number of files.
• has the same content, by comparing them with a diff tool (kdiff3 or, as suggested below, WinMerge if you are on Windows)

Using a diff tool alone is not enough: you need to do it revision by revision.
