Automate and simplify the process of managing one-way read-only subtree splits.
Git subsplit relies on subtree being available. If is not available
in your version of git (likely true for versions older than 1.7.11)
please install it manually from here.
git-subsplit can be installed and run standalone by executing
git-subsplit.sh directly.
git-subsplit can also be installed as a git command by:
./install.sh
There is a known bug in the underlying git-subtree command that this script uses. Your disk will eventually run out of inodes because a cache directory isn't cleaned up after every run. I suggest you to create a cronjob to clean the cache directory every month:
0 0 1 * * rm -rf <path to>/dflydev-git-subsplit-github-webhook/temp/$projectname/.subsplit/.git/subtree-cache/*
- dflydev GitHub WebHook (PHP)
Initialize subsplit with a git repository url:
git subsplit init https://github.com/react-php/react
This will create a working directory for the subsplit. It will contain a clone of the project's upstream repository.
Update the subsplit repository with current state of its upstream repository:
git subsplit update
This command should be called before one or more publish commands
are called to ensure that the repository in the working directory
has been updated from its upstream repository.
Publish to each subtree split to its own repository:
git subsplit publish \
src/React/EventLoop:[email protected]:react-php/event-loop.git \
--heads=master
The pattern for the splits is ${subPath}:${url}. Publish can receive
its splits argument as a space separated list:
git subsplit publish "
src/React/EventLoop:[email protected]:react-php/event-loop.git
src/React/Stream/:[email protected]:react-php/stream.git
src/React/Socket/:[email protected]:react-php/socket.git
src/React/Http/:[email protected]:react-php/http.git
src/React/Espresso/:[email protected]:react-php/espresso.git
" --heads=master
This command will create subtree splits of the project's repository branches and tags. It will then push each branch and tag to the repository dedicated to the subtree.
Passing --update to the publish command is a shortcut for calling
the update command directly.
To specify a list of heads (instead of letting git-subsplit discover them from the upstream repository) you can specify them directly. For example:
--heads="master 2.0"
The above will only sync the master and 2.0 branches, no matter which branches the upstream repository knows about.
Do not sync any heads.
To specify a list of tags (instead of letting git-subsplit discover them from the upstream repository) you can specify them directly. For example:
--tags="v1.0.0 v1.0.3"
The above will only sync the v1.0.0 and v1.0.3 tags, no matter which tags the upstream repository knows about.
Do not sync any tags.
Ordinarily tags will not be synced more than once. This is because in general tags should be considered more or less static.
If for some reason tags need to be resynced from scratch (history changed so tags might point to somewhere else) this flag will get the job done.
As little output as possible.
Does not actually publish information to the subsplit repos for each
subtree split. Instead, display the command and execute the command
with --dry-run included.
Allows you to see the logic behind the scenes.
Inspiration for writing this came from Guzzle's goal of providing components as individually managed packages. Having seen this already done by Symfony and liking how it behaved I wanted to try and see if I could solve this problem in a general case so more people could take advantage of this workflow.
Much time was spent checking out git-subtree and scripts written for
managing React's components.
