Retrieve specific commit from a remote Git repository

Question

Is there any way to retrieve only one specific commit from a remote Git repo without cloning it on my PC  The structure of remote repo is absolutely same as that of mine and hence there won t be any conflicts but I have no idea how to do this and I don t want to clone that huge repository   I am new to git  is there any way

This works best   git fetch origin specific commit git checkout -b temp FETCH HEAD   name  temp  whatever you want   this branch might be orphaned though

If the requested commit is in the pull requests of the remote repo  you can get it by its ID     Add the remote repo path  let s call it  upstream   git remote add upstream https   github com repo project git    checkout the pull ID  for example ID  60   git fetch upstream pull 60 head  amp  amp  git checkout FETCH HEAD

Starting with Git version 2 5   Q2 2015   fetching a single commit  without cloning the full repo  is actually possible   See commit 68ee628 by Fredrik Medley  moroten   21 May 2015   Merged by Junio C Hamano -- gitster -- in commit a9d3493  01 Jun 2015     You now have a new config  on the server side   uploadpack allowReachableSHA1InWant      Allow upload-pack to accept a fetch request that asks for an object that is reachable from any ref tip  However  note that calculating object reachability is computationally expensive    Defaults to false    If you combine that server-side configuration with a shallow clone  git fetch --depth 1   you can ask for a single commit  see t t5516-fetch-push sh   git fetch --depth 1    testrepo  git  SHA1   You can use the git cat-file command to see that the commit has been fetched   git cat-file commit  SHA1       git upload-pack  that serves  git fetch  can be told to serve   commits that are not at the tip of any ref  as long as they are   reachable from a ref  with uploadpack allowReachableSHA1InWant   configuration variable      The full documentation is      upload-pack  optionally allow fetching reachable sha1      With uploadpack allowReachableSHA1InWant configuration option set on the server side   git fetch  can make a request with a  want  line that names an object that has not been advertised  likely to have been obtained out of band or from a submodule pointer     Only objects reachable from the branch tips  i e  the union of advertised branches and branches hidden by transfer hideRefs  will be processed    Note that there is an associated cost of having to walk back the history to check the reachability       This feature can be used when obtaining the content of a certain commit    for which the sha1 is known  without the need of cloning the whole   repository  especially if a shallow fetch is used        Useful cases are e g          repositories containing large files in the history     fetching only the needed data for a submodule checkout     when sharing a sha1 without telling which exact branch it belongs to and in Gerrit  if you think in terms of commits instead of change numbers     The Gerrit case has already been solved through allowTipSHA1InWant as every Gerrit change has a ref          Git 2 6  Q3 2015  will improve that model  See commit 2bc31d1  commit cc118a6  28 Jul 2015  by Jeff King  peff    Merged by Junio C Hamano -- gitster -- in commit 824a0be  19 Aug 2015        refs  support negative transfer hideRefs      If you hide a hierarchy of refs using the transfer hideRefs config  there is no way to later override that config to  unhide  it    This patch implements a  negative  hide which causes matches to immediately be marked as unhidden  even if another match would hide it    We take care to apply the matches in reverse-order from how they are fed to us by the config machinery  as that lets our usual  last one wins  config precedence work  and entries in  git config  for example  will override  etc gitconfig        So you can now do    git config --system transfer hideRefs refs secret git config transfer hideRefs   refs secret not-so-secret       to hide refs secret in all repos  except for one public bit   in one specific repo      Git 2 7  Nov Dec 2015  will improve again   See commit 948bfa2  commit 00b293e  05 Nov 2015   commit 78a766a  commit 92cab49  commit 92cab49  commit 92cab49  03 Nov 2015   commit 00b293e  commit 00b293e  05 Nov 2015   and commit 92cab49  commit 92cab49  commit 92cab49  commit 92cab49  03 Nov 2015  by Lukas Fleischer  lfos   Helped-by  Eric Sunshine  sunshineco    Merged by Jeff King -- peff -- in commit dbba85e  20 Nov 2015        config txt  document the semantics of hideRefs with namespaces      Right now  there is no clear definition of how transfer hideRefs should   behave when a namespace is set    Explain that hideRefs prefixes match stripped names in that case  This is how hideRefs patterns are currently   handled in receive-pack       hideRefs  add support for matching full refs      In addition to matching stripped refs  one can now add hideRefs patterns that the full  unstripped  ref is matched against    To distinguish between stripped and full matches  those new patterns must be prefixed with a circumflex        Hence the new documentation   transfer hideRefs       If a namespace is in use  the namespace prefix is stripped from each reference before it is matched against transfer hiderefs patterns    For example  if refs heads master is specified in transfer hideRefs and   the current namespace is foo  then refs namespaces foo refs heads master   is omitted from the advertisements but refs heads master and   refs namespaces bar refs heads master are still advertised as so-called    have  lines    In order to match refs before stripping  add a   in front of   the ref name  If you combine   and      must be specified first      R   mentions in the comments the config uploadpack allowAnySHA1InWant  which allows upload-pack to accept a fetch request that asks for any object at all   Defaults to false    See commit f8edeaa  Nov  2016  Git v2 11 1  by David  novalis  Turner  novalis       upload-pack  optionally allow fetching any sha1      It seems a little silly to do a reachabilty check in the case where we   trust the user to access absolutely everything in the repository       Also  it s racy in a distributed system -- perhaps one server   advertises a ref  but another has since had a force-push to that ref    and perhaps the two HTTP requests end up directed to these different   servers

You can simply fetch a single commit of a remote repo with  git fetch  lt repo gt   lt commit gt    where     lt repo gt  can be a remote repo name  e g  origin  or even a remote repo URL  e g  https   git foo com myrepo git   lt commit gt  can be the SHA1 commit   for example  git fetch https   git foo com myrepo git 0a071603d87e0b89738599c160583a19a6d95545   after you fetched the commit  and the missing ancestors  you can simply checkout it with  git checkout FETCH HEAD   Note that this will bring you in the  detached head  state

Finally i found a way to clone specific commit using git cherry-pick  Assuming you don t have any repository in local and you are pulling specific commit from remote   1  create empty repository in local and git init  2  git remote add origin  url-of-repository   3  git fetch origin  this will not move your files to your local workspace unless you merge   4  git cherry-pick  Enter-long-commit-hash-that-you-need   Done This way  you will only have the files from that specific commit in your local   Enter-long-commit-hash   You can get this using -  git log --pretty oneline

You only clone once  so if you already have a clone of the remote repository  pulling from it won t download everything again  Just indicate what branch you want to pull  or fetch the changes and checkout the commit you want   Fetching from a new repository is very cheap in bandwidth  as it will only download the changes you don t have  Think in terms of Git making the right thing  with minimum load   Git stores everything in  git folder  A commit can t be fetched and stored in isolation  it needs all its ancestors  They are interrelated     To reduce download size you can however ask git to fetch only objects related to a specific branch or commit   git fetch origin refs heads branch refs remotes origin branch   This will download only commits contained in remote branch branch  and only the ones that you miss   and store it in origin branch  You can then merge or checkout   You can also specify only a SHA1 commit   git fetch origin 96de5297df870 refs remotes origin foo-commit   This will download only the commit of the specified SHA-1 96de5297df870  and its ancestors that you miss   and store it as  non-existing  remote branch origin foo-commit

I did a pull on my git repo   git pull --rebase  lt repo gt   lt branch gt    Allowing git to pull in all the code for the branch and then I went to do a reset over to the commit that interested me   git reset --hard  lt commit-hash gt   Hope this helps

You can simply fetch the remote repo with   git fetch  lt repo gt    where     lt repo gt  can be a remote repo name  e g  origin  or even a remote repo URL  e g  https   git foo com myrepo git    for example   git fetch https   git foo com myrepo git    after you fetched the repos you may merge the commits that you want  since the question is about retrieve one commit  instead merge you may use cherry-pick to pick just one commit    git merge  lt commit gt      lt commit gt  can be the SHA1 commit   for example   git cherry-pick 0a071603d87e0b89738599c160583a19a6d95545   or  git merge 0a071603d87e0b89738599c160583a19a6d95545   if is the latest commit that you want to merge  you also may use FETCH HEAD variable     git cherry-pick  or merge  FETCH HEAD

In a project we had a problem so that we had to revert back to a certain commit  We made it with the following command successfully  git reset --hard  lt commitID gt

I think  git ls-remote    http   git-scm com docs git-ls-remote   should do what you want  Without force fetch or pull
