i need to squash several commits into a single one in a automated
way. I know that there is interactive rebase, which can also be
automated using GIT_SEQUENCE_EDITOR. Unfortunately my history is very
large and i need to squash deep down in the history several times. So
using interactive rebase seems not to be the right tool.
I wonder if i can solve this task using filter-branch? I have a file
that list the SHA1s for each squash operation per line. All SHA1s of
a line are in chronological order (youngest to oldest), or in other
words: the first SHA1 is the child of the second, and so on.
Use git-replace do construct a squashed commit that replaces the last
child in each run such that its parent points to the parent of the first
in the run. Then use a git-filter-branch without filters to burn the
parenthood into the history.
Using grafts (which are only about parentage, and are purely local) with
filter-less git-filter-branch might be easier than git-replace.
If you have the following history:
... <--- O <--- A <--- B <--- C <--- ...
and you want to squash A, B, C into
... <--- O <----------------- C <--- ...
simply add the following to .git/info/grafts
<sha-1 of C> <sha-1 of O>
for example with
echo "$(git rev-parse C) $(git rev-parse C^^^)" >>.git/info/grafts
Check if the history is correct e.g. with "git log --graph --oneline",
then use filter-branch.
BTW. do you know if it is possible to run filter-branch without
replacing replaces?
Just for completeness, yet another way to do scripted history rewriting
is to use git-fast-export + some editing script (e.g. reposurgeon[1]) +
git-fast-import.
