A restore by a normal user always printed "Restore did not preserve file ownership", even when every entry came out with its recorded owner and group. The check looked only at whether restore ran as root.
After a restore by a normal user, warnIfOwnershipNotPreserved in internal/vaultik/restore.go now reads the owner and group each restored entry has on disk, compares them with the recorded ones, and warns once if any differ. A restore as root never warns, as before. The warning text is unchanged.
It compares what is on disk, not the recorded ids with the user's own, because a new entry does not always get the user's group: on macOS, and in a setgid directory on Linux, it takes the group of the directory it is created in.
Judgement call: an entry that is not on disk after the restore, such as one that failed, is not compared.
Judgement call: an entry on a filesystem that reports no owner (only the in-memory one the tests use) is not compared.
Unverified: not run on a Mac. The test for entries that take their directory's group uses a setgid directory on Linux and is skipped unless run as root, as make test runs.
Not covered by a test: the call from finishRestore, which a test run as root does not reach.

internal/vaultik/restore.go, warnIfOwnershipNotPreserved: the warning is now skipped whenever every recorded owner and group equals the restoring user's effective ids. That rests on the assumption that a normal user's restore gives every entry those ids, which is false on macOS, where a new file or directory always takes the group of the directory it is created in, and on Linux inside a setgid directory. For example, a normal user who restores to /tmp on macOS gets every entry with group wheel instead of the recorded group and no longer sees any warning, where before this change the warning was printed. The doc comment ("any other user's restore leaves every entry with that user's ids") states the same false assumption. Acceptable: for a normal user, compare the owner and group each restored entry actually has on disk after the restore with the recorded ones and warn when any differ, and test it on real files: one restore whose entries match the record (no warning) and one where an entry's group does not (warning).
internal/vaultik/restore_ownership_warning_test.go: no case has more than one entry with another owner or group, so the tests still pass if the warning is printed once per such entry instead of once per restore. Acceptable: a case with two such entries that checks the warning appears exactly once.
Unverified: the macOS case was not run on a Mac; it follows from macOS giving each new entry the group of its directory.

1. `internal/vaultik/restore.go`, `warnIfOwnershipNotPreserved`: the warning is now skipped whenever every recorded owner and group equals the restoring user's effective ids. That rests on the assumption that a normal user's restore gives every entry those ids, which is false on macOS, where a new file or directory always takes the group of the directory it is created in, and on Linux inside a setgid directory. For example, a normal user who restores to `/tmp` on macOS gets every entry with group `wheel` instead of the recorded group and no longer sees any warning, where before this change the warning was printed. The doc comment ("any other user's restore leaves every entry with that user's ids") states the same false assumption. Acceptable: for a normal user, compare the owner and group each restored entry actually has on disk after the restore with the recorded ones and warn when any differ, and test it on real files: one restore whose entries match the record (no warning) and one where an entry's group does not (warning).

changed title from Warn about restored ownership only when an owner differs to Warn about restored ownership only when an entry's owner or group differs2026-10-14 02:37:13 +02:00
The warning now compares the owner and group each restored entry has on disk with the recorded ones, no longer the recorded ids with the restoring user's; the doc comment says so. Tested on real files: a restore whose entries match their record prints nothing, and one whose entries take a setgid directory's group prints the warning.
That second test restores two such entries and checks the warning appears exactly once.

internal/vaultik/restore_ownership_warning_test.go: in every case, each entry ends up with the owner it was recorded with. The only mismatch tested is a group mismatch, so the tests still pass if warnIfOwnershipNotPreserved compares only the group and drops the owner.Uid != file.UID check. The definition of done in #316 asks for a restore where some owners do not match. Acceptable: a case where an entry is recorded with another owner than the one it gets on disk (for example otherOwnerID), which checks that the warning is printed. It needs no setgid directory, so it runs as any user.
Commit message: the body is about 137 words, over the limit of about 120. Acceptable: a body of about 120 words or fewer, for example by leaving out what the PR body already says.
Unverified: the macOS case, which was not run on a Mac.

A restore by a normal user always warned that file ownership was not
preserved, even when every entry came out with its recorded owner and
group. The owner and group each restored entry has on disk are now
compared with the recorded ones, and the warning is printed once if any
differ. The comparison is made on disk because on macOS, and in a setgid
directory on Linux, a new entry takes the group of its directory, not
the user's.
Judgement call: an entry that is not on disk after the restore is not compared.
Unverified: not run on a Mac; the directory-group test runs only as root.
