2017-07-14Add `# shellcheck` directives to quiet shellcheck, add PKGBUILD.protoLuke Shumaker
The added PKGBUILD.proto file is so that shellcheck can know know what to expect that a PKGBUILD sets.
2017-07-14lib/archroot.sh: subvolume_delete_recursive: support arbitrary recursionLuke Shumaker
The `-xdev` flag to `find` makes it not recurse over subvolumes; so it only supports recursion with depth=1. Fix this by having the function recursively call itself.
2017-07-14makechrootpkg: sync_chroot: Make more general.Luke Shumaker
This is inspired by the thought that went in to the delete_chroot is_subvolume commit. sync_chroot($chrootdir, $copydir) copies `$chrootdir/root` to `$copydir`. That seems a little silly; why do we care about "$chrootdir"? Have it just be sync_chroot(source, destination) like every other sync/copy command. Where this becomes tricky is check to decide if we are going to use btrfs subvolumes or not. We don't care if "$source/.." is on btrfs; the root could be a directly-mounted subvolume, but and the destination could be another subvolume of the same btrfs mounted somewhere else. The things we do care about are: - The source is a btrfs subvolume (so that we can snapshot it) - The source is on the same filesystem as the directory that the copy will be created in. - If the destination exists: * that it is not a mountpoint (so that we can delete and recreate it) * that it is a btrfs subvolume (so that we can quickly delete it) On the last point, it isn't necessary for creating the new snapshot, just for quick deletion. That can be a separate check, where we use regular `rm` for deleting the existing copy, but use subvolume snapshots for creating the new one.
2017-07-14makechrootpkg: delete_chroot: Fix the is-btrfs-subvolume check.Luke Shumaker
First of all, it ran `is_btrfs "$chrootdir"` to decide if it was on btrfs, but $chrootdir wasn't defined locally; it just happens to work because $chrootdir was defined in main(). (I noticed this because in Parabola, it is called differently, so $chrootdir was empty). So I was tempted to just change it to `is_btrfs "$copydir"`, but if $copydir is just a regular directory on a btrfs filesystem, then it It would leave much of $copydir intact. What we really care about is if $copydir is a btrfs subvolume; which we can check by combining the is_btrfs check with inspecting the inum of the directory. I put this combined check in lib/archroot.sh:is_subvolume. https://lists.archlinux.org/pipermail/arch-projects/2013-September/003901.html
2017-04-05Add a "License:" tag to all code files.Luke Shumaker
In cases where there is no license specified, the file is tagged as "License: Unspecified". Obviously, that is not ideal, but it highlights the fact, and I hope that it encourages whoever has the authority to specify the license to do so. On that note, to anyone who may have the authority to specify the license of files in devtools: the current licence of many files is GPLv2 with no option for later versions; I impore you to re-license them to have the "or any later version" option.
2017-04-05Add '#!/hint/bash' headers to non-executable bash files.Luke Shumaker
This provides a cross-editor hint that the syntax of the file is Bash.
2017-03-07archbuild/makechrootpkg: Delete subvolumes in rootsJan Alexander Steffens (heftig)
The systemd package creates a subvolume at /var/lib/machines (through tmpfiles), if it can. We need to delete this subvolume before we can delete the parent subvolume. Look through the root for inodes with the number 256. These identify subvolume roots.
2017-03-07lib/archroot.sh: Add is_btrfs helperJan Alexander Steffens (heftig)
2017-03-07lib/archroot.sh: Simplify check_rootJan Alexander Steffens (heftig)
Move the function and save the orig_argv right along it.
