Thread: Working with git repo tagged versions
Howdy folks, Occasionally I need to grab an older release from git based on a tag rather than a branch, eg the REL8_3_10 tag vs the REL8_3_STABLE branch. I used to know how to do this in CVS, but I find I tend to revert to grabbing tarballs now that we're on git. So, I'm wondering if anyone knows a way to do this directly from git clone (or similar), and ideally as a shallow clone (ie. I just need a copy of the code at that tag, rather than needing the repo for development purposes). If anyone knew a way to do this down to a specific commit, that would also be interesting to know. Thanks in advance. Robert Treat conjecture: xzilla.net consulting: omniti.com

I just did this: $ git-new-workdir postgresql/.git/ tmpChecking out files: 100% (3903/3903), done.$ cd tmp$ git checkout REL8_3_10 That does use a shadow clone. Basically, git checkout assumes a tag, unless you -b for a branch. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +

Maybe the github clone can be helpful -- for example try an URL such as https://github.com/postgres/postgres/tarball/cf22e851b6ae8737f3e767dffcadf1722fbb36a7 -- Álvaro Herrera <alvherre@commandprompt.com> The PostgreSQL Company - Command Prompt, Inc.

FWIW, this is what we use in the script that makes release tarballs:
export GIT_DIR=[ where your git clone is ] git archive ${COMMITHASH} | tar xf - -C pgsql

No, git checkout assumes a branch, and if it doesn't find a branch, it looks for a commit by the given name, and a tag is one way of naming a commit. The -b option creates a new branch.
