The VM-side tools were built for a terminal; a -tool may lose its in-VM usability if that makes sb-builder simpler. So the -hint logic of mkhint moves into `sbb-remote` (Python, JSON answers) and the -upstream check moves to the desktop. mkhint is not extended. - -## Facts this design rests on - -Verified on the VM, in the mkhint source (`~/Programming/GIT/mkhintfile/mkhint`, -1.4.0, 2291 lines) and in slackrepo (`../GITHUB/slackrepo`): - -- The VM has 607 hints, all in `hintdir`, none in subdirectories and none in - the SBo tree. 594 carry only `DELREQUIRES`, 13 carry - `VERSION` + `ARCH` + `DOWNLOAD` + `MD5SUM`, one carries `OPTIONS`.

It edits only the `DELREQUIRES` line. sbshadow - (slackrepo_setup) runs it after every sync: that is where the 594 - DELREQUIRES-only hints come from, and why they exist (slackrepo must not - build deps -current does not need). Until now sbshadow ran it on `--no` - previews too. -- The VM's nvchecker config has 64 stanzas named after the packages, plus a - `[__config__]` with oldver, newver and keyfile. nvchecker v2.22 is - installed on the desktop, with a GitHub token in - `~/.config/nvchecker/keys.toml`.

A package with a phantom dep always has such a hint, so `hint-new` - never sees one. -- slackrepo `update <item>` builds an item that exists, built or not - (`update_command` calls `build_command`). -- The phantom deps list on the VM (`/root/.config/mkhint/phantom-deps`) has - 18 entries. -- Two packages use bundled-dep manifests: neovim (url mode) and openvino - (sha mode, GitHub submodules). That code is about 470 lines of mkhint. - -## Scope - -In: upstream check, version update, new hint, delete hint, -`--no-dl` as `DOWNLOAD="no"`, diff and revert. - -Out, for good (the Hints screen covers them): mkhint `--list`, `--versions`, -`--review`, `--strip-version`, `--info`, `--clean`. - -Out, later (phase 4b, which then removes mkhint and nvchecker from the VM): -bundled-dep reconcile for neovim and openvino, and a helper `fix-current` -that sbshadow calls in place of `mkhint -F`, with the phantom deps list -moved into the helper config as its single source. Also out: generating nvchecker stanzas -for new packages (add them to `nvchecker.toml` by hand), free text hint -editing, migration of `NODOWNLOAD=yes` lines (none exist). - -## Part 1: upstream check, on the desktop - -- `nvchecker.toml` in the repo root: the VM's 64 stanzas, without - `[__config__]`. Stanza name = package name. Git-tracked, edited by hand. -- `sb_builder/upstream.py` runs nvchecker through `QProcess` (as `remote.py` - runs `virsh`) with a fixed argv: `nvchecker -c <tmp>/nvchecker.toml - --logger json`. The temp dir holds a generated config: a `[__config__]` - with `keyfile` (from the GUI config, when the file exists), followed by the - repo file's text. No oldver, newver or `nvtake`: the comparison is against - the hints. -- Result: `{pkg: version}` and `{pkg: error}` from the JSON log. A package - without a result, or a failed run (exit status, stderr), shows as - `nvchecker error` with the reason in the tooltip. -- Upstream versions are stored with `-` as `_` (mkhint's `_normalize_version`): - `-` is illegal in a SlackBuild version, so upstream `2026-10-14` is - packaged `2026_10_14`. The comparison and `hint-update` use that form. -- A package is outdated when its upstream version differs from the hint - `VERSION`, or from the `.info` `VERSION` when the hint has none. Versions - are compared as strings; no ordering is attempted. - -GUI config gains `[hints] nvchecker_keyfile`, default -`~/.config/nvchecker/keys.toml` (expanded). A missing keyfile is not an -error: nvchecker runs without a token. - -## Part 2: helper (`sbb-remote` 0.5.0) - -### Config - -New key `manifest_packages` (below). `remote/config.example.toml` shows it. - -### Arguments - -- package: `PKGNAME` and present in the repo (as for slackrepo jobs). -- version: `^[A-Za-z0-9._+-]+$`, at most 64 characters. -- hint path: always `<hintdir>/<pkg>.hint`. If `find_hint` returns a - different file for the package (a hint earlier in slackrepo's search - order), every hint command refuses: "hint lives at <path>, not managed". -- packages with a bundled-dep manifest are named in config key - `manifest_packages`, default `["neovim", "openvino"]`. `hint-update` and - `hint-new` with a version refuse them: "bundled deps: use mkhint until - phase 4b". - -### Job kinds - -- `hint-update <pkg>=<ver>... [--no-dl]`: per package, in order: compute the - new text (apply the version, below), then back the hint up to `.bak` and - write atomically. A failure (download, missing `.info` VERSION) leaves the - hint and its old `.bak` untouched, logs `<pkg>: failed: <why>` and - continues with the next package. A package without a hint gets a new one - built as `hint-new` does. The last log line is - `SBB-RESULT {"ok": [pkg...], "failed": [[pkg, why]...]}`. Exit status 1 - when any package failed. -- `hint-new <pkg> [<ver>] [--no-dl]` (since 0.6.0 `hint-new <pkg>... [--no-dl]`, - no version, see the UI design): refuses when the hint exists. Builds - the hint from the `.info` as mkhint does, without phantom deps (see the - facts), then applies the version when given. No `.bak` (a stale - one is removed); revert means delete. - -These jobs never sign, so they do not check the signing key. Their argv is -the helper itself: `python3 sbb-remote _hint <kind> <args>`, validated again -there. Job ids now allow a hyphenated kind (`...-hint-update`). - -`job-result <id>`: the last `SBB-RESULT` object of a job's log. - -### Applying a version - -1. A hint without `VERSION` is first pinned from the `.info`: its - `VERSION`, `DOWNLOAD*` and `MD5SUM*` lines, plus `ARCH="x86_64"` when the - hint has no `ARCH`, are put in front of the hint's text. Old version = the - hint's `VERSION`. With no version given (`hint-new <pkg>`), steps 2 and 3 - are skipped. -2. Replace old by new everywhere in the file except inside `MD5SUM*` - values. When either contains `_`, also the `-` forms. When old contains - `.`, also its dotless form inside URLs, as a whole number (no digit before - or after). -3. Without `--no-dl`: for `DOWNLOAD`/`MD5SUM` and - `DOWNLOAD_x86_64`/`MD5SUM_x86_64`, split the values on whitespace (hint - values may continue over lines with `\`). Skip a pair whose value is empty, - `UNSUPPORTED` or `UNTESTED`. Download the first URL with `urllib` - (timeout 60 s, streamed into `hashlib.md5`, nothing kept on disk) and - replace its md5; keep the md5s of the other URLs. Write values back one - URL per line with ` \` continuation, as mkhint does. -4. With `--no-dl`: nothing is downloaded. Every `DOWNLOAD*` and `MD5SUM*` - assignment is removed (whole multi-line values) and `DOWNLOAD="no"` is - written, because `DOWNLOAD_$ARCH` would override it. - -Hint text is edited as text, not regenerated, so comments, order and other -keys stay as they are. An assignment is `KEY="..."` (the value may span -lines inside the quotes) or `KEY=word`, at line start. - -### Commands (answer at once, not jobs) - -- `hint-diff <pkg>`: `{"bak": text|null, "current": text|null}`. Both null - is an error ("no backup"). -- `hint-revert <pkg>`: when a `.bak` exists, move it over the hint (also - recreating a deleted hint); when there is no `.bak` and the hint exists, - delete the hint (reverting a `hint-new`). Returns `{"ok": true}`. -- `hint-delete <pkg>`: move the hint to `.bak`. Errors when there is no hint. - -`.bak` is one level deep and overwritten by each change, the mkhint -convention. - -### Version - -`VERSION` 0.5.0 in `remote/sbb-remote` and `sb_builder/__init__.py`. - -## Part 3: GUI - -### Hints screen (`sb_builder/hints_tab.py`, ribbon entry and `Open > Hints`) - -- Rows: every package with a stanza in `nvchecker.toml` or a hint in - `hintdir`. Columns: checkbox, package, hint version, `.info` version, - upstream, state. Versions come from the existing `inventory` call. -- States: `outdated`, `current`, `no stanza`, `not checked`, - `nvchecker error` (stderr in the tooltip). Filter chips per state and a - text filter on the name, as in the Packages tab. -- Buttons: - - **Check upstream**: runs Part 1 over the whole file, fills the upstream - column, checks the outdated rows. Results live for the session. - - **Update selected**: starts `hint-update pkg=ver ...` for the checked - rows that have an upstream version; a **No download** checkbox adds - `--no-dl`. - - **Delete hint**: confirm dialog, then `hint-delete` for the current row. -- Jobs go through the Jobs tab like every other job. - -### After a hint job - -When a `hint-update` or `hint-new` job ends, the GUI reads -its `SBB-RESULT` line and opens a dialog with one entry per changed package: -a unified diff (`difflib`) of `hint-diff`, and a **Revert** button per -package. Failed packages are listed with their reason. The dialog ends with -**Build these**, which starts `slackrepo update --preview` for the changed -packages that were not reverted (update builds unbuilt items too), and -**Close**. Revert is offered once per package: a second one would delete -the restored hint. After Revert or Delete the inventory is reloaded. - -Each diff is fetched when its package is selected. - -### Packages detail pane - -- No hint: **New hint**, with an optional version field and a **No - download** checkbox, starts `hint-new`. -- Hint present: **Open in Hints** selects the package in the Hints screen. - -## Error handling - -- Bad arguments, unmanaged hint paths and manifest packages are refused by - the helper before a job starts; the GUI shows the message. -- A download failure (HTTP status, timeout, DNS) fails that package only and - leaves its hint as it was. -- Writes are atomic (temp file in the same directory, `os.replace`). -- nvchecker missing or failing on the desktop affects only the upstream - column; the rest of the screen works. -- A job without an `SBB-RESULT` line (killed, lost) opens no dialog; the - log shows what happened and `hint-diff` still works per package. - -## Testing - -- `test_remote.py`: an `http.server` thread serves fixture files for md5. - Version swap forms (plain, `_`/`-`, dotless in URL only, md5 hex not - touched), multi-line `DOWNLOAD`/`MD5SUM` with continuation md5s kept, - `UNSUPPORTED` skipped, `--no-dl` removing `DOWNLOAD_x86_64` and writing - `DOWNLOAD="no"`, a download failure restoring the hint while the next - package still updates, `SBB-RESULT` contents, `hint-new` from `.info`, - a DELREQUIRES-only hint pinned from the `.info`, new -> revert, update -> diff -> - revert, delete -> revert, manifest package refusal, unmanaged hint path - refusal, bad version and package rejection. -- `test_upstream.py`: generated config, JSON log parsing, states (hint - version, `.info` fallback), the repo file has no `[__config__]`, `Checker` - against a fake `nvchecker` on `PATH` and a missing one. No network. -- `test_gui.py`: Hints screen with a fake remote and injected upstream - results (states, checked rows, Update selected argv), diff dialog Revert - call. - -## Deploy (asks first) - -1. `./install.sh --remote` with helper 0.5.0. -2. slackrepo_setup's sbshadow, which no longer runs `mkhint -F` on `--no`. -3. mkhint, nvchecker and `/root/.config/{mkhint,nvchecker}` stay on the VM - until phase 4b. |
