error: Could not read changeset about git-sizer

[mhagger]

That problem is generated from within Git itself. It could be a bug in Git or, more likely, corruption in your repository. Try running

git fsck --no-dangling

to check for corruption. If that doesn't report any problems, try running

git rev-list --objects --date-order --all | wc -l

, which is an approximation of what git-sizer runs (piped to wc so that you are not inundated with output).

@mhagger we got the some output for git fsck --no-dangling command which is listed below :-

Is it possible to continue further Or I need to fix this above issue.

[mhagger]

@Kaleesastha: the git fsck output indicates that your repository is corrupt (it is missing objects). You need to fix the corruption.

• It might be that the missing objects are only reachable from reflogs. If so, then

    git reflog expire --stale-fix --expire-unreachable=all --all
  

  might fix it.

• If you have backups or other copies of the repository (e.g., maybe your co-workers also have clones), you might be able to scavenge the missing objects from there.

• If neither of those work, then it might be that the missing objects are only reachable from some unneeded and/or obsolete references that you could delete.

If none of those work, you might be forced to rewrite history to excise the missing objects. But that is well beyond the scope of git-sizer.

Good luck!
