Follow-up of this so-question: if I have a shallow clone, how to fetch all older commits to make it a full clone?
回答1:
You can run git fetch --depth=1000000 (assuming the repository has less than one million commits).
回答2:
The below command (git version 1.8.3) will convert the shallow clone to regular one
git fetch --unshallow
Then, to get access to all the branches on origin (thanks @Peter in the comments)
git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"
git fetch origin
回答3:
I needed to deepen a repo only down to a particular commit.
After reading man git-fetch, I found out that one cannot specify a commit, but can specify a date:
git fetch --shallow-since=15/11/2012
For those who need incremental deepening, another man quote:
--deepen=<depth>Similar to --depth, except it specifies the number of commits from the current shallow boundary instead of from the tip of each remote branch history.
回答4:
You can try this:
git fetch --update-shallow
回答5:
None of the above messages did the trick. I'm trying to work with git tags starting from a shallow clone.
First I tried
git fetch --update-shallow
which kind of worked half-way through. Yet, no tags available!
git fetch --depth=1000000
This last command really fetched the tags and I could finally execute
git checkout -b master-v1.1.0 tags/v1.1.0
and be done with it.
