Re: [aur-general] AUR 4 = Migrating 1 git to git-per-package
If you follow the pattern I do, of having a directory within your git repository (I call mine aur) that contains directories named after each package's $pkgbase (or $pkgname if not a split package), then I should be able to post my script here (after I've tested it a little more on aur-dev) later tonight.

Re: [aur-general] AUR 4 = Migrating 1 git to git-per-package
Hi all, TL;DR: https://github.com/ido/packages-archlinux/blob/master/bin/import-to-aur4.sh I maintain my AUR packages in https://github.com/ido/packages-archlinux, under a subdirectory called aur, with each PKGBUILD in its own folder under that aur folder. So, for example, ceph-git is in $WORKDIR/aur/ceph-git/PKGBUILD... To migrate this to AUR 4.0 per-package git repositories, I used git subtree and git filter-branch (to get around that pesky server-side update hook that looks for a valid .SRCINFO). 0) It does all of its work in a temp dir (/tmp/importaur4.X by default; export TMPDIR=$HOME/ to do it in your $HOME for example). It clones a fresh copy of the upstream one-big-git-repository (use file:/// if you want to do this from a local repo). It accepts two arguments: $1 = URL to repo to git clone, $2 = subdirectory relative path from workdir root. Warning: Use ssh-add/ssh-agent to add your AUR ssh key otherwise you will have to do a lot of typing! 1) It uses git subtree split to split out packages into their own branches (this works much like git filter-branch --subdirectory-filter). 2) It uses the code from pkgbuild-introspection to create a SRCINFO file. 3) It uses git filter-branch --tree-filter to copy in the .SRCINFO it generated for any commits on the per-package branches that do not already have a .SRCINFO file in them. 4) It uses git push to push the per-package branches (aur4/$pkgbase) to the master branch on the aur-dev server. 5) It creates a superproject git repository for you in /tmp/importaur4./ to track all of your per-package repos in one place, which has git submodules for each per-package repository. This is for convenience and is located in /tmp/importaur4./aur4-superproject. Please send pull requests for any improvements you make; I wrote this quickly with the intent of using it for my own packages. It fails on some repositories, mostly due to the server-side update hook in AUR4 right now. Example failures shown below. The script is located at: https://github.com/ido/packages-archlinux/blob/master/bin/import-to-aur4.sh Enjoy!
