* catalyst: Rewrite ismount() to use libmountMatt Turner2020-10-301-1/+1
| | | | | | | | libmount is provided by util-linux, so this adds a dependency on sys-apps/util-linux[python]. A later patch will make more extensive use of this API. Signed-off-by: Matt Turner <mattst88@gentoo.org>
* catalyst: Make and use squashfs snapshotsMatt Turner2020-04-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a number of problems with catalyst's snapshot system. It was built around using the build system's portdir and had no control over what was in that portdir or when it was updated. As a result, when a stage build failed, it was difficult to tell what the snapshot consistet of precisely or whether it contained a particular recent fix. With snapcache disabled, ebuild repo snapshots were tar'd and compressed and then unpacked into the stage chroot which is an unnecessarily expensive process. Moreover, a porttree has more than 100k small files, which are stored extremely inefficiently on most file systems—a whole porttree is usually around 700M on disk. Just removing all of those files during the cleaning stage is an expensive operation. Instead, we make a compressed squashfs image and mount it in the build chroot. The porttree has many duplicate files, and squashfs deduplicates the files and then compresses, so the result is very efficiently packed: ~38M with gzip -9 compression. The snapshot target has been modified to generate a squashfs image from a bare ebuild git repo. Piping git-archive to tar2sqfs generates the squashfs image in less than 10 seconds on a modern system. The git repo is fetched with --depth=1 to minize bandwidth and disk usage, and git gc is run after fetch to minimize disk usage. Storage requirements for the git ebuild repo with metadata are ~70M. The squashfs snapshot is stored in /var/tmp/catalyst/snapshots/ by default with a name <repo_name>-<git sha1>.sqfs. With this convention, we know the exact point in history that the snapshot was taken. The catalyst-auto script can use the sha1 to get a deterministic timestamp, so that it is independent on when `catalyst -s` was run, but is instead the timestamp of the commit date of the repo's git SHA1.
