Subject: just curious: what influences a commit hash?
Date: Thu, 05 Mar 2009 07:36:32 +0100 [thread overview]
Message-ID: <20090305063632.42880@gmx.net> (raw)
Hi,
being new to git I did some experiments with commits looking at the hashes. What I observed:
* The same commit (same file, same committer, same message) into different empty repositories (git init) gives different hashes. So I assume that also the time of the commit influences the hash. Is this intended? For what reason?
* Having created two repositories exactly the same way (the history is the same except for the commit times and hashes) I applied the same patch (using git am) and again I got different hashes for these commits. So in some way also the repository/branch influences the hash of a commit!?
From reading the Git user's manual, chapter 10, object storage format, I was not expecting this. Can someone explain or give a link to a more detailed description?
thank you,
Wolfgang
