Commit id changed to 11 digits from 7 digits.

I moved a git repository present in one stash instance to another by first cloning it using git clone --mirror command and then using git push --mirror command. 

After doing so, I noticed that commit id has changed to 11 digits in new stash instance instead of 7 digits present earlier.

The new format seems like to be the <old_7_digit>+<new_4_digit>.

Can you please let me know the reason behind this?

My commit hashes are 40 digits long. the short versions still 7 (git bash command line).

The short versions are for display only, you should not rely on their length. Where do you have a problem with this?

The length of the short version is typically chosen so that you do not have collisions / duplicates in large projects. I just checked our Stash and it also has 11 digits for the short hash. You will note that this is used for a nicer display only, when you click on such a hash code link, it uses the long form in the link and internally.

Hello Rajat,

Thank you for your inquire.

Could you please let us know:

  1. I noticed that commit id has changed to 11 digits in new stash instance instead of 7 digits present earlier., Where have you noticed that change (Stash UI)?
  2. what is the Stash version (Origin)
  3. what is the Stash version (Destination)

I have ran the following commands in attempt to replicate the issue:

$ git clone --mirror ssh://git@stash:7999/mir/original.git
Cloning into bare repository 'original.git'...
remote: Counting objects: 3, done.

Receiving objects: 100% (3/3), done.
Checking connectivity... done.
$ cd original.git
 
$ git push --mirror ssh://git@stash:7999/mir/mirror.git

Writing objects: 100% (3/3), 217 bytes | 0 bytes/s, done.

To ssh://git@stash:7999/mir/mirror.git
 * [new branch]      master -&gt; master

Please, notice if you run "git log" from either ORIGINAL or MIRROR the hash should be the same and this is what matters:

$ git log
commit 76b2ace641b92e67ac16db7daf28125b7533499b

    add foo
