################################################################ | |
This sample hook safeguards topic branches that have been | |
published from being rewound. | |
The workflow assumed here is: | |
* Once a topic branch forks from "master", "master" is never | |
merged into it again (either directly or indirectly). | |
* Once a topic branch is fully cooked and merged into "master", | |
it is deleted. If you need to build on top of it to correct | |
earlier mistakes, a new topic branch is created by forking at | |
the tip of the "master". This is not strictly necessary, but | |
it makes it easier to keep your history simple. | |
* Whenever you need to test or publish your changes to topic | |
branches, merge them into "next" branch. | |
The script, being an example, hardcodes the publish branch name | |
to be "next", but it is trivial to make it configurable via | |
$GIT_DIR/config mechanism. | |
With this workflow, you would want to know: | |
(1) ... if a topic branch has ever been merged to "next". Young | |
topic branches can have stupid mistakes you would rather | |
clean up before publishing, and things that have not been | |
merged into other branches can be easily rebased without | |
affecting other people. But once it is published, you would | |
not want to rewind it. | |
(2) ... if a topic branch has been fully merged to "master". | |
Then you can delete it. More importantly, you should not | |
build on top of it -- other people may already want to | |
change things related to the topic as patches against your | |
"master", so if you need further changes, it is better to | |
fork the topic (perhaps with the same name) afresh from the | |
tip of "master". | |
Let's look at this example: | |
o---o---o---o---o---o---o---o---o---o "next" | |
/ / / / | |
/ a---a---b A / / | |
/ / / / | |
/ / c---c---c---c B / | |
/ / / \ / | |
/ / / b---b C \ / | |
/ / / / \ / | |
---o---o---o---o---o---o---o---o---o---o---o "master" | |
A, B and C are topic branches. | |
* A has one fix since it was merged up to "next". | |
* B has finished. It has been fully merged up to "master" and "next", | |
and is ready to be deleted. | |
* C has not merged to "next" at all. | |
We would want to allow C to be rebased, refuse A, and encourage | |
B to be deleted. | |
To compute (1): | |
git-rev-list ^master ^topic next | |
git-rev-list ^master next | |
if these match, topic has not merged in next at all. | |
To compute (2): | |
git-rev-list master..topic | |
if this is empty, it is fully merged to "master". |
