tags.yaml imports by diffing (#868)
* tags.yaml imports by diffing

tags.yaml declares three sections (Tags, tagged files, tagged Zim
entries), so its import reads the file once, diffs it against a snapshot,
and writes only the differences, with the file's version, in one write.
An unchanged import writes nothing.

A removed Tag is deleted with its tagged files and Zim entries; a
Collection using it loses only the Tag.  A removed tagged file or Zim
entry is untagged.  A tagged file whose Tag the config does not list is
skipped.  prepare finds files without a FileGroup on disk, skips missing
ones before the write, moves Zim entries of a replaced Zim to the newest
one, and maps a file named by a secondary member to its group; the
config is then saved with the database's paths.

Moving a tagged FileGroup counts as a tags.yaml change (ORM, the bulk
move, and a refresh that changes the primary file), so a restart before
the save does not untag it.

Sections can define `same` (a tagged file without a date matches any
date), and prepare can count skipped rows.

* A removed Tag leaves no Download that would apply it

The tags import removes a deleted Tag's name from every Download's
tag_names and from the tag_names and channel_tag_name its settings pass
on (a change to download_manager.yaml, which is then saved).  Applying a
Tag that does not exist fails the download, and it is retried.  Once
tags.yaml is imported, a newer download_manager.yaml drops names no Tag
has, and is saved without them.

A replaced Zim's entry tags move to the newest Zim of the same parsed
name, by the date in its name (as migrate_outdated_zim_tags picks it),
not by name prefix and path order.

WROLPi

Create your own off-grid library.

WROLPi Logo

WROLPi is a self-contained collection of software to help you survive the world Without Rule of Law.

WROLPi is intended to be run on a Raspberry Pi with an optional external drive attached. It serves up it's own Wi-Fi network so that any user with a laptop/tablet/phone can connect and use the library created by the maintainer.

Try WROLPi!

You can try out WROLPi by running the docker containers.

  1. Install docker-ce and docker-compose
  2. Copy the latest WROLPi code.
    • git clone https://github.com/lrnselfreliance/wrolpi.git
  3. Change directory into the code base.
    • cd wrolpi
  4. Initialize git submodules
    • git submodule update --init
  5. Build the containers.
    • docker-compose build --parallel
  6. Create volumes.
    • docker volume create --name=openstreetmap-data
    • docker volume create --name=openstreetmap-rendered-tiles
  7. Initialize the database (SQLite in the media directory).
    • docker-compose run --rm api db upgrade
  8. Start the docker containers.
    • docker-compose up
  9. Browse to WROLPi.

More Docker documentation is available in docker/README.md

Install WROLPi

Full installation instructions are in INSTALL.md. Pick the option that matches your hardware:

  • WROLPi Portable (Live USB) — boot a complete WROLPi from a USB stick on any x86 PC or laptop. Nothing is installed to the computer; the first boot creates a persistence partition on the USB so your library, database, and configuration survive reboots.
  • Debian 13 — install WROLPi onto an x86 PC or laptop.
  • Raspberry Pi — install WROLPi onto a Raspberry Pi with an external drive.
  • Docker — run the WROLPi containers on an existing Linux host.

Charter

Guiding Principals

  1. Storage is cheaper than power.
  2. Two is one, one is none.
  3. Run silently.
  4. Primary, secondary, tertiary.
  5. Secure as a bookshelf in your home.

Physical properties

  1. A WROLPi instance should be capable of running with a minimal of hardware:
    • Raspberry Pi
    • SD card
    • External USB hard drive
    • Power supply and cables
    • Wi-Fi USER device such as a phone, tablet, or laptop.
  2. A WROLPi instance should consume a minimal amount of electricity during WROL event. It is expected power will be scarce when WROLPi is needed most.

User expectations

  1. A WROLPi instance should be run and maintained by a person (MAINTAINER) with a moderate amount of Linux and Raspberry Pi experience. It is expected that they should be able to do this using only the documentation on their WROLPi.

Software properties and capabilities

  1. A WROLPi instance should be able to "factory-reset" itself without any outside services.
  2. WROLPi should function completely without any internet services.
  3. A user should have easy access to their data if WROLPi fails:
    • For example, a user can watch their videos by navigating a short and intuitive directory structure and opening the video in their preferred video player.
  4. WROLPi should be self-documented. The UI should contain a tutorial for USERS as well as the MAINTAINER.
    • If the UI isn't functional, the code should be documented such that a user can restore functionality.
  5. WROLPi should favor pre-processing, rather than processing during a WROL event. Such as re-encoding a video, or processing captions. This is to ensure that when a user adds content during non-WROL time, the processing for optimum performance is already done for a WROL event.
