2017-07-05lib/archroot.sh: subvolume_delete_recursive: support arbitrary recursionLuke Shumaker1-3/+6
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.
2017-07-05makechrootpkg: sync_chroot: Make more general.Luke Shumaker1-0/+8
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 "$source/.." is on btrfs; the root could be a directly-mounted subvolume, but and the destination could be another subvolume of the same btrfs mounted somewhere else. The things we do care about are: - The source is a btrfs subvolume (so that we can snapshot it) - The source is on the same filesystem as the directory that the copy will be created in. - If the destination exists: * that it is not a mountpoint (so that we can delete and recreate it) * that it is a btrfs subvolume (so that we can quickly delete it) On the last point, it isn't necessary for creating the new snapshot, just for quick deletion. That can be a separate check, where we use regular `rm` for deleting the existing copy, but use subvolume snapshots for creating the new one.
2017-07-05makechrootpkg: delete_chroot: Fix the is-btrfs-subvolume check.Luke Shumaker1-1/+10
First of all, it ran `is_btrfs "$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
2017-04-05lib/common.sh: Make it safe to include multiple times.Luke Shumaker1-0/+3
This is similar to common C #ifdef guards. I was tempted to wrap the entire thing in the if/fi, rather than use 'return' to bail early. However, that means it won't execute anything until after it reaches 'fi'. And if `shopt -s extglob` isn't executed before parsing, then it will syntax-error on the extended globs. One solution would have been to move `shopt -s extglob` up above the include-guard. But the committed solution is all-around simpler.
2017-04-05lib/common.sh: Adjust to work properly with `set -u`.Luke Shumaker1-3/+4
2017-04-05Avoid using string interpolation; use printf format strings instead.Luke Shumaker1-5/+5
This involves extending the signature of lib/common.sh's `stat_busy()`, `lock()`, and `slock()`. The `mesg=$1; shift` in stat_busy even suggests that this is what was originally intended from it.
2017-04-05Add a "License:" tag to all code files.Luke Shumaker3-0/+4
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 Shumaker3-0/+6
This provides a cross-editor hint that the syntax of the file is Bash.
2017-04-05lib/common.sh: Make setup_workdir()/cleanup() safe for programs to not useLuke Shumaker1-4/+7
2017-04-05lib/common.sh: lock, slock: Create directories for locks if necessary.Luke Shumaker1-0/+2
2017-04-05lib/common.sh: lock, slock: Allow locks to be inherited.Luke Shumaker1-2/+10
Allow for locks to be inherited. Inheriting the lock is something that mkarchroot could do previously, but has since lost the ability to do. This allows for the programs to be more compos-able. Do this by instead of unconditionally opening $file on $fd, first check if $file is already open on $fd; and go ahead use it if it is. The naive way of doing this would be to `$(readlink /dev/fd/$fd)` and compare that to `$file`. However, if `$file` is itself a symlink; or there is a symlink somewhere in the path to `$file`, then this could easily fail. Instead, check `[[ "/dev/fd/$fd" -ef "$file" ]]`. Even though the Bash documentation (`help test`) says that `-ef` checks for if the two files are hard links to eachother, because it uses stat(3) (which resolves symlinks) to do this check, it also works with the /dev/fd/ soft links.
2017-04-05lib/common.sh: add 'lock_close'; use it as appropriate.Luke Shumaker1-0/+8
`lock_close FD` is easier to remember than 'exec FD>&-`; and is especially easier if FD is a variable (though that isn't actually taken advantage of here). This uses Bash 4.1+ `exec {var}>&-`, rather than the clunkier `eval exec "$var>&-"` that was necessary in older versions of Bash. Thanks to Dave Reisner for pointing this new bit of syntax out to me the last time I submitted this (back in 2014, 4.1 had just come out).
2017-03-07archbuild/makechrootpkg: Delete subvolumes in rootsJan Alexander Steffens (heftig)1-0/+20
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.

2014-09-22common: remove unreachable statementDave Reisner1-2/+1
We run from a non-interactive shell, so the exec which is inevitably called will replace the current process and 'die' will never run under any circumstances. This also fixes a bug with the su fallback which would cause multiple arguments to be concatenated without any whitespace between them.

Fixes a breakage introduced in 6db31cc16a80442 which leads to errors being masked from makechrootpkg.

2013-11-04find_cached_package: avoid adding duplicatesDave Reisner1-2/+7
If PKGDEST is set when makepkg was run, the package will be present in find_cached_package's search path by default, causing an error. This also fixes a display bug which causes no output to be shown when multiple packages are found. Fixes FS#37626.

2013-11-01common: implement find_cached_packageDave Reisner1-0/+69
This function (currently) searches through $PWD and $PKGDEST looking for a tarball matching the requested package name, architecture, and pkgver. If found, it writes the full path to the located package to stdout and returns 0, else 1. If more than 1 match is found, it's treated as an error and the user will need to figure out what to do. Use this in checkpkg and commitpkg, which previously implemented their own less complete logic, to locate the build artifacts they rely on.

2013-08-08common: Properly forward arguments from die to errorDave Reisner1-1/+1

2013-05-03lib/common.sh: Introduce locking helper functionsJan Alexander Steffens (heftig)1-0/+24
Reduces code duplication. With makechrootpkg not calling mkarchroot anymore, the lock handover protocol is unneeded. arch-nspawn does not do any locking, so add protection to archbuild.

2012-02-12archrelease: Validate tags before releasingLukas Fleischer1-0/+20
Compare every single tag with a list of valid tags. This prevents broken releases which occurred whenever someone made a typo on the command line: $ ./archrelease community i686 ==> ERROR: archrelease: Invalid tag: "community" (use -f to force release) Since the list is used in the ZSH completion as well, break it out to a separate file and move it to "lib/". Also, add a command line parameter to allow for releasing to an unknown repository when necessary.
