# sb-builder: phantom deps (phase 4b, part 1)
Date: 2026-10-20
Status: approved
Builds on: `2026-10-20-sb-builder-phase4-design.md`, `2026-10-20-sb-builder-ui-design.md`
## Goal
Manage the -current phantom deps (deps SBo packages still require but
Slackware -current ships) from sb-builder: the list, suggestions from the
tree, and the `DELREQUIRES` sweep that mkhint's `-F` does today. Found when
-current added zenity: 8 SBo packages require it, nothing in the GUI could
mark it.
## Facts
- When a package enters the official tree, SBo removes it. A `REQUIRES`
name that matches no package of the repo is then left behind. On
2026-10-20 the tree has 140 such names, zenity among them; the 17 on
mkhint's list (`/root/.config/mkhint/phantom-deps`) are all among them.
- sbshadow ends with `mkhint -F` (skipped on `--no`). mkhint's `-F` merges
the phantom deps found in each `.info` `REQUIRES` into the hint's
`DELREQUIRES`, `.bak` first, a minimal hint when there is none; it never
removes entries.
- openvino moved into the personal overlay; only neovim still needs mkhint's
bundled-dep logic.
## Helper (`sbb-remote` 0.7.0)
- Config: `phantom_deps_file`, default `/etc/sb-builder/phantom-deps`: one
name per line, `#` comments, mkhint's format. Missing file = empty list.
`manifest_packages` default becomes `["neovim"]`.
- `phantom-list`: `{"deps": [...], "suggestions": [{"name", "needed_by":
[...]}]}`. Suggestions: every `REQUIRES` name (without `%README%`) that
matches no package of the repo and is not on the list, sorted, with the
packages requiring it.
- `phantom-add <name>...`, `phantom-remove <name>...`: names must match
`PKGNAME`, need not exist in the repo. Rewrites the file atomically,
comments kept, one name per line, no duplicates. Returns the new list.
- Job kind `fix-current`: for every package whose `.info` `REQUIRES` names a
listed dep, merge those deps into `DELREQUIRES` of `<hintdir>/<pkg>.hint`
(union, first seen order; `.bak` only when it changes; a new hint has just
that line and no `.bak`). Unmanaged hint paths fail that package. Log one
line per changed hint, then `SBB-RESULT`. Add only, like mkhint.
- `fix-current-now`: the same sweep run inline, its log on stdout, for
sbshadow.
## sbshadow (slackrepo_setup)
The end of a non-preview run calls `sbb-remote fix-current-now` in place of
`mkhint -F`; without sbb-remote it says so and skips, as it does for mkhint
today.
## GUI
Hints ribbon: **Phantom deps…** (between Delete hint and the end). A
non-modal dialog:
- the list, one name per row, with **Remove** for the selected rows;
- a name field with **Add**;
- **Suggestions**: tickable rows `name needed by a, b, c`, **Add ticked**;
- **Apply**: starts `fix-current` (the list itself is saved by each Add or
Remove at once); the usual diff dialog follows, with Revert per package.
## Deploy (asks first)
1. Helper 0.7.0.
2. `/etc/sb-builder/phantom-deps` from mkhint's file (17 entries).
3. sbshadow.
## Out
neovim bundled deps (phase 4b, part 2), removing mkhint and nvchecker from
the VM (part 3), removing `DELREQUIRES` entries when a dep leaves the list.
