From 7c93a058c8d7e21aea2aad8f3114c8422bf6faf7 Mon Sep 17 00:00:00 2001 From: Laurent Bercot Date: Fri, 2 Oct 2026 02:22:28 +0000 Subject: First part of the format-upgrade support in repo In order to work across major bumps, we need to add a call to s6-rc-format-upgrade before s6-rc-update in the s6-rc-set-install sequence of commands. s6-rc-format-upgrade only works when the db is exactly the same across s6-rc versions. That means we need to have the source version of the current live set at all times, in order to compile it with the new s6-rc version before upgrading and then updating. So: 1. we take a snapshot of the source version of a set every time we commit. 2. we refuse to install if we don't have the snapshot. 3. we add s6-rc-format-upgrade to the processing chain 4. for cleanup: after installing, we delete all the snapshots of the set except the one that corresponds to the newly installed live set. This commit implements 1: taking the snapshot. It's a regular s6-rc-set-copy, using an internal name. We refactor s6-rc-set-copy and s6-rc-set-delete to have primitives we can use internally. Wait for later commits before using repo, else you'll fill your repository with snapshots that won't get cleaned up. TBD: how to store the s6-rc version in the compiled db. We probably need to add a small file in there. --- src/include/s6-rc/repo.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/include') diff --git a/src/include/s6-rc/repo.h b/src/include/s6-rc/repo.h index 56ec5bf..1615507 100644 --- a/src/include/s6-rc/repo.h +++ b/src/include/s6-rc/repo.h @@ -41,6 +41,8 @@ extern int s6rc_repo_touch (char const *) ; extern int s6rc_repo_touchset (char const *, char const *) ; extern int s6rc_repo_checkset (char const *, char const *) ; extern int s6rc_repo_setuptodate (char const *, char const *) ; +extern int s6rc_repo_setcopy (char const *, char const *, char const *, unsigned int) ; +extern void s6rc_repo_setdelete (char const *, char const *) ; extern int s6rc_repo_makesetbundles (char const *, char const *, unsigned int) ; extern int s6rc_repo_makedefbundle (char const *, char const *, char const *) ; -- cgit v1.3.1
