How to convert a Git shallow clone to a full clone?

Question

Follow-up of this so-question: if I have a shallow clone, how to fetch all older commits to make it a full clone?

Do you consider to mark @sdram's answer? That's the correct one. — Ionică Bizău, Jul 13 '14 at 10:17

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

This doesn't undo the --single-branch side effect. To do that, edit .git/config and change fetch = +refs/heads/BRANCHNAME:refs/remotes/origin/BRANCHNAME to fetch = +refs/heads/*:refs/remotes/origin/* – Peter Cordes Jul 29 '14 at 21:36

This doesn't create local branches tracking the remote branches, so you still need to checkout -b BRNAME origin/BRNAME to get that set up. – Peter Cordes Jul 29 '14 at 21:45

This only works if the repo is marked as shallow. I can't remember how, but there are situations where you can end up with an incomplete repo without having explicitly done a shallow clone. @svick's https://stackoverflow.com/a/6802238/260122 is the answer that works every time. – clacke Apr 27 '17 at 05:45

`git fetch --unshallow --update-head-ok origin '+refs/heads/*:refs/heads/*'` worked for me – gzaripov May 25 '20 at 09:32
@gzaripov's one-liner **did not** work for me. It resulted in a local snapshot of remote branches that could not be configured with tracking. The three-lines given in this answer, however, do work. – M. Anthony Aiello Sep 17 '20 at 15:27

@gzaripov under what circumstances is using the porcelain `--update-head-ok` useful? – Tom Hale Feb 08 '22 at 09:06

`fatal: --unshallow on a complete repository does not make sense` If 799 people agree, something must be wrong at my end. I've yet to determine what. – Sridhar Sarnobat May 25 '22 at 04:05
Note: this option is available to `git pull`, as well, i.e., `git pull --unshallow`. – TravisCarden Aug 29 '22 at 14:36

EDIT: git fetch --unshallow now is an option (thanks Jack O'Connor).

You can run git fetch --depth=2147483647

From the docs on shallow:

The special depth 2147483647 (or 0x7fffffff, the largest positive number a signed 32-bit integer can contain) means infinite depth.

Now that `git fetch --unshallow` exists (as in @sdram's answer), this answer is no longer the best one. – Jack O'Connor Apr 14 '14 at 08:41

@sdram's answer did not work for me (git version 2.1.1), but this answer did. – Kijewski Nov 07 '14 at 14:48

Neither answer worked for me. Both commands succeeded in fetching all the missing commits, but when I try to push new commits, I get an error about the server not knowing about 'shallow' refs – Tyguy7 Sep 19 '15 at 00:08

`git fetch --depth=2147483647` is the largest possible depth to provide to the command. – clacke Apr 27 '17 at 05:47

I used `git fetch --unshallow`, but it still does not show all the branches. – Sid Oct 03 '17 at 14:29

@Sid, https://stackoverflow.com/questions/11623862/git-fetch-doesnt-fetch-all-branches fixed that for me. – Bryan Larsen Oct 10 '18 at 13:25
Tip: on an unstable internet connection, we can incrementally `git fetch --depth=1000` then again `git fetch --depth=10000` and so on. – Zzz0_o Apr 07 '21 at 11:19
Use of `git fetch --depth=2147483647` is sufficient within Azure DevOps Pipeline. – kris Mar 23 '23 at 08:13

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.

Two ways to achieve Shallow Clone to Deep Clone. :

Used the following steps to download the branch: (This downloads the shallow copy of the branch and then converts it into a Full Clone i.e bring complete branch and its history).

a. git clone -b branch http://git.repository/customSP01.git --depth 1

This does a shallow clone (with the depth-option) only fetches only one single branch (at your requested depth).

b. cd customSP01
c. git fetch --depth=100
d. get fetch --depth=500
....
e. git fetch --unshallow

//The above command will convert the shallow clone to regular one. However, this doesn’t bring all the branches:

Then, to get access to all the branches.

f. git remote set-branches origin '*'

[This Step can also be done manually by editing following line in .git/config.

fetch = +refs/heads/master:refs/remotes/origin/master

to (replace master with *):

fetch = +refs/heads/*:refs/remotes/origin/* ]

g. git fetch -v

This converts the Shallow Clone into Deep Clone with all the History and Branch details.

You can avoid steps f and g, if you use the below instead of command present in step a. to do the shallow clone:

git clone -b branch --no-single-branch http://git.repository/customSP01.git --depth 1

I only needed step F. I did `git clone --depth=1 `, but then `git fetch --unshallow` did not fix it, nor did `git fetch --all`: remote branch list still just had master & HEAD. Step F fixed it. — Tom, Aug 20 '21 at 21:26

You can try this:

git fetch --update-shallow

--update-shallow doesnt work if shallow clone is performed with depth value. – Renuka Kulkarni May 18 '23 at 15:31

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.

What's the downvote for? Please explain so I can improve upon this. Thank you. – Gen.Stack Dec 15 '20 at 12:10
I didn't downvote, but I think it might be because 'git checkout -b' is used to create a new local branch. So, I don't think it does what might be expected in the context of your answer. – Kevin Buchs Jan 29 '22 at 19:02

Configurations that helped with the error is (In GitLab) For each project :

On the top bar, select Main menu > Projects and find your project.
On the left sidebar, select Settings > CI/CD. Expand General pipelines.
Under Git strategy, choose git fetch, under Git shallow clone, enter a value, 1000, the maximum value for GIT_DEPTH Read More - https://gitlab.yourcompany.com/help/ci/pipelines/settings#limit-the-number-of-changes-fetched-during-clone{}

In the .gitlab-ci-yml (this should be done before any command that calls GitVersion.exe)
