# Changelog
|
||||
|
||||
## [0.3.1] - 2026-04-10
|
||||
|
||||
### Fixed
|
||||
- **Issue #4**: LXC/Container-Kompatibilität — systemd-Hardening (`PrivateTmp`, `ProtectSystem`, etc.)
|
||||
verursacht Error 226/NAMESPACE in LXC-Containern. Installer erkennt Container-Umgebung automatisch
|
||||
und bietet ein Drop-in an. Zusätzlich liegt `systemd/lxc-compat.conf` als Vorlage im Repo.
|
||||
- **Issue #5**: `WorkingDirectory=/opt/pdf-ocr-hotfolder` in der systemd Template-Unit ergänzt —
|
||||
ohne diesen Eintrag konnte das Python-Modul nicht gefunden werden.
|
||||
- **Issue #6**: Auf Debian 12 bietet der Installer bei betroffenen Ghostscript-Versionen (10.0.0–10.02.0)
|
||||
jetzt automatisch an, bookworm-backports zu aktivieren und GS zu upgraden (statt nur zu warnen).
|
||||
|
||||
## [0.3.0] - 2026-04-09
|
||||
|
||||
### Added
|
||||
- Neue Config-Sektion `[output]` mit:
|
||||
- `name_mode` — Platzierung des Tags im Dateinamen: `"prefix"`, `"suffix"` (vor Extension), `"none"`
|
||||
- `name_tag` — verbatim einzufügender String, z.B. `"OCR_"` oder `"_OCR"`
|
||||
- `original_on_success` — `"delete"` (alter Default) oder `"archive"`
|
||||
- `archive_dir` — Zielverzeichnis für `"archive"`, mit Kollisions-Schutz (Timestamp-Suffix)
|
||||
- Runtime-Validierung der Output-Config in `check_output_config()`
|
||||
- 20 neue Tests für `build_output_name()`, `check_output_config()` und `process_pdf()`
|
||||
mit allen Kombinationen aus Modus + Original-Behandlung
|
||||
|
||||
### Changed
|
||||
- `process_pdf()` nimmt jetzt `output_cfg: OutputConfig` als Pflicht-Argument
|
||||
|
||||
## [0.2.2] - 2026-04-09
|
||||
|
||||
### Fixed
|
||||
- **Issue #3**: Ghostscript 10.0.0–10.02.0 (Debian 12 default) zerschießen OCR mit PDF/A + `skip_text=true`.
|
||||
- `config.example.toml`: `pdfa_level = ""` als sicherer Default
|
||||
- Runtime-Preflight: Prüft `gs --version` wenn `pdfa_level` gesetzt ist, bricht mit klarer Fehlermeldung ab
|
||||
- `install.sh`: warnt bei betroffenen GS-Versionen mit Upgrade-Hinweis auf bookworm-backports
|
||||
|
||||
### Added
|
||||
- `is_ghostscript_broken()` / `detect_ghostscript_version()` in `pdf_ocr_hotfolder.service`
|
||||
- 19 weitere pytest-Tests für GS-Versions-Detection (parametrisiert) und Preflight-Kombinationen

### LXC/Container: Error 226/NAMESPACE
|
||||
In LXC-Containern schlagen systemd-Hardening-Optionen fehl. Der Installer erkennt Container automatisch und bietet ein Drop-in an. Manuell:
|
||||
```bash
|
||||
sudo mkdir -p /etc/systemd/system/pdf-ocr-hotfolder@.service.d/
|
||||
sudo cp /opt/pdf-ocr-hotfolder/systemd/lxc-compat.conf \

sudo systemctl restart 'pdf-ocr-hotfolder@*'
|
||||
```
|
||||
|
||||
### Ghostscript PDF/A-Bug auf Debian 12
|
||||
GS 10.00.0–10.02.0 (Debian 12 Default) zerstört OCR bei `pdfa_level` + `skip_text=true`. Der Installer bietet automatisch bookworm-backports an. Manuell:
|
||||
```bash
|
||||
echo 'deb http://deb.debian.org/debian bookworm-backports main' | \
|
||||
sudo tee /etc/apt/sources.list.d/bookworm-backports.list
|
||||
sudo apt update && sudo apt install -t bookworm-backports ghostscript
|
||||
```
|
||||
|
||||
### veraPDF-Validierung schlägt immer fehl
