swiftonhpss/HISTORY

This git repository is a child (of sorts) of the git.gluster.com/glusterfs.git
repository, where origins of its contents come from the "swift" and "ufo"
directories of its parent repository. The goal was to acknowledge that the
gluster-swift integration work is in fact a separate and independent coding
effort intersecting at the packaging level with GlusterFS upstream and its
derivative products, for example, Red Hat's RHS.

To create this repository, we followed the steps below (in pseudo script
form), which assumes that one is using an up-to-date glusterfs.git
locally-cloned repository:

$ #
$ # First list all of the changes to the "ufo" directory:
$ #
$ git checkout master
$ git log --oneline ufo

$ #

$ #
$ # Now we see that we have the entire history above.
$ #
$ # Next we need to generate patch files to apply to a clean tree.
$ # To do that, we start by listing the patches for the swift tree
$ # in reverse order and explicitly requesting a numbered format-
$ # patch:
$ let idx=1
$ for i in $(git log --oneline --reverse swift | awk '{ print $1 }') ; do
$     git checkout $i
$     git format-patch --start-number $idx -1
$     ((idx++))
$ done
$ #
$ # Then we need to switch back to top-of-tree and do the same for
$ # the "ufo" directory:
$ #
$ git checkout master
$ for i in $(git log --oneline --reverse ufo | awk '{ print $1 }') ; do
$     git checkout $i
$     git format-patch --start-number $idx -1
$     ((idx++))
$ done
$ #
$ # At this point we have a set of sequentially numbered diffs that
$ # can be applied to any git repo ... with two exceptions: patches
$ # 0056-*.patch and 0061-*.patch have references to files that do not
$ # exist ahead of time, so one has to edit out the cli* and .gitignore
$ # diffs from those two patches, respectively, and then one can run
$ # the following command to create a new repo:
$ #
$ cd /tmp  # Or what ever directory you want to store the new repo in
$ mkdir newdir
$ cd newdir
$ git init
$ git am /path/to/*.patch  # ... generated above
$ git remote add -f origin ssh://<user>@git.gluster.com/gluster-swift.git
$ git pull --no-commit origin master
$ #
$ # By default, a git pull will provide its own commit message, but
$ # we list one below to be explicit in case some environments don't
$ # have the proper "editor" set.
$ #
$ git commit -s -m "Merge up to master before committing initial changes"
$ #
$ # Once we have "Push" commit rights, the following updates the tree:
$ #
$ git push origin master
