Git create full file patches to download/distribute?

Question

Either i'm going nuts or nobody likes/liked this feature, but a long time ago i used to use subversion with sourceforge system. I had the ability to create full file patches for commits done.

I cannot figure out anyway to create these in git, all i want is the files that were changed from XX commit and only those files in their entirety so that i could hand them off to someone/upload just those files to a location.

As it currently stands i'm stuck reuploading the entire project because i have nothing that tells me what was changed. Since we're also on a shared web host there is no way to get git on the server without upgrading to more expensive package.

I've tried

git archive --output=/home/username/temp.zip <commit id>

which put everything into a zip nicely but it did just that, it put everything. Also tried a variation of format-patch but that didn't seem to work.

Answer 1

It seems that I misunderstood what you wanted in my other answer. git archive can take a list of paths to include in the archive, so you could do:

git archive -o /tmp/foo.zip HEAD $(git diff --name-only oldcommit HEAD)

If your filenames contain surprising characters, though, it would be safer to do:

git diff -z --name-only oldcommit HEAD | xargs -0 git archive HEAD -o /tmp/blah.zip --

Answer 2

The first thing to try would be to save the output of git diff , which might be sufficient in your situation:

git diff oldcommit > test.patch

If you have changed binary files since then, you could try:

git diff --binary oldcommit > test-with-binaries.patch

In that case you'd then need to apply the patch with git apply . Otherwise, I would create a new branch based on oldcommit , do a squashed merge from master , commit the result and and use git format-patch to produce the patch. That method (and several other solutions to your problem) are described in more detail in the answers to this similar stackoverflow question: How do you squash commits into one patch with git format-patch?
