Those of you maintaining unofficial ROMs that need some device specific patches to the android platform that are not (yet) merged into the official sources often face the same problem: When syncing with upstream you either have to cherry-pick your patches again manually, or for those changes that are not committed there may be merge errors.
Additionally, when there are many patches in various repos it can get hard to keep track of them.
I faced the same situation while working on my phone, which needs changes not merges into any official sources except for NamelessROM. And those of you who know me, know that I like scripts doing the work for me. ;)
So I decided to write a tiny script to do all that for me.
Sure, I could have written a script like
But I just don't like hardcoding, and maintaining the script would also be way, way harder.
So I came up with this solution:
Storing the fetch URLs as well as the commit IDs in arrays. Then I can call one after another fully automatic via for-loops.
One issue remained, though: if a cherry-pick fails the next commits would also fail. Which is why the repo gets automatically reset if a cherry-pick doesn't apply properly.
An example script can be found HERE or in the attachments.
Now, the most important part for you: How do you make the script compatible with your ROMs sources?
There are just a few values you have to take care of:
remote_name specifies the name that should be used for fetching (doesn't really matter, it just helps keeping track of what this remote is)
paths specifies the paths to the repos the script is gonna cycle through.
commit_id[name] specifies the commit IDs of the repo "name". While "name" is the path to the repo, but with underscores instead of slashes. Example: if your path is "system/core", the name you have to specify would be "system_core".
repo_url[name] specifies the URL of the repo to fetch. The naming is the same as in commit_id with underscores.
That's it. You can specify as many repos as you need, the script will cycle one after the other.
For an example on how to update the script with more repos, you may want to take a look at THIS commit
Now, how to use the script?
It's as simple as it could be:

- Set up the build environment (. build/envsetup.sh)
- Execute the script from whereever you want (. cherry-pick.sh)
