Tam Nguyen Duc f3704021cd Add mandatory ZIM metadata for zimcheck (#14)
* Add mandatory ZIM metadata for zimcheck

ZIM archives were missing two pieces of metadata that the spec and
zimcheck treat as mandatory: a Description and the Illustrator_48x48@1
favicon Kiwix shows as the book icon. A Name was missing too.

Every archive now writes a Name and a Description, defaulting the
description to a host-derived line when --description is not given. When
the mirror has a usable icon, the favicon is rescaled to a 48x48 PNG and
stored as Illustrator_48x48@1 with an image/png MIME, reusing the icon
discovery and square-fit scaling the app packer already uses.

AddMetadataBytes is added to the zim writer so a binary metadata value
can carry its own MIME instead of being forced to text/plain.

Verified by reading the output back through the libzim engine: all
mandatory keys are present and the illustrator decodes as a 48x48 PNG.

* Update docs for ZIM metadata and current flags

Document the new mandatory metadata in the packing guide and the Kiwix
compatibility note, and default --description in the CLI reference.

While in the reference, bring it back in line with the code: add the
--app and --icon pack flags (shipped in v0.2.0 but never documented),
drop the --max-asset-mb clone flag that does not exist, and fix a stale
--resume mention in the configuration layout.

Release notes What changed in each kage release. 40

The authoritative, commit-level history lives in CHANGELOG.md and on the releases page. This page summarises each version.

v0.2.1

Packed ZIM archives now carry the metadata Kiwix expects, so a mirror shows up in a ZIM reader's library with a title, a description, and an icon instead of as a blank entry.

  • Mandatory metadata is always written. Every archive now gets a Name and a Description (a line derived from the host when --description is not given), the two fields zimcheck flags as missing otherwise.
  • The favicon becomes the book icon. When the mirror has a usable icon (an apple-touch-icon.png, favicon.png, or a PNG-based favicon.ico), kage rescales it to a 48x48 PNG and stores it as Illustrator_48x48@1, which is the icon Kiwix shows for the archive in its library. A site with no usable icon is packed without one rather than with a broken image.

v0.2.0

Double-click apps, so a packed mirror opens like a real desktop app instead of a terminal program.

  • kage pack --app wraps the viewer in a double-click app with the site's favicon as its icon. The flag builds on the binary format, so it composes with --base (including a webview base) and --icon. On macOS that is a .app bundle; on Linux, with a Linux --base, an AppImage-style .AppDir that becomes a single .AppImage when appimagetool is installed. The icon is pulled from the mirror automatically, or set with --icon.
  • A GUI-subsystem Windows base ships in the release as kage_<version>_windows-gui_<arch>.zip. Pack a viewer onto it with --format binary --base and the resulting .exe opens with no console window behind it.
  • Smarter cross-platform packing. kage reads the base binary's executable header to detect its target OS, so a Windows viewer always gets a .exe name and the right run hint, regardless of how the base file is named.

v0.1.2

A security fix for how kage launches Chrome, clearer crawl errors, and a container image that actually runs.

  • Chrome keeps its sandbox on by default. Earlier versions launched Chrome with --no-sandbox on every run, which switched off the browser's main security boundary even on an ordinary desktop where the sandbox works fine (#10). The sandbox now stays on, and is dropped only where it genuinely cannot start: inside a container (detected from IN_DOCKER or /.dockerenv) or when running as root. Whenever it is dropped, kage says so on stderr, so the choice is never silent.
  • Transient asset failures retry. A download that hits a 403/429, a 5xx, or a network blip is retried with a short backoff, which recovers files that bot-protection rejects on the first request of a burst. Permanent failures like a 404 are not retried.
  • Clearer crawl errors. Each failure now logs a classified reason (HTTP 403 Forbidden, timed out, ...), the URL, and the page that referenced it, and the end-of-run summary lists what went wrong instead of printing only a count.
  • The container image runs. Chrome aborted in the image with chrome_crashpad_handler: --database is required, so the crash reporter is now disabled inside a container, and the kage user has a writable home (the mounted /out volume) so output, resume state, and Chrome's profile no longer fail with a permission error (#7).

v0.1.1

Packing, so a clone can travel as one file instead of a folder.

  • kage pack <mirror-dir> collapses a mirror into a single distributable file. --format zim (the default) writes an open ZIM archive, the same format Kiwix uses, so the file opens in any ZIM reader and not just kage. --format binary appends that archive to a copy of kage to make a self-contained executable that serves the site offline when run. Packing is deterministic, so the same mirror produces a byte-identical file.
  • kage open <file.zim> serves a packed ZIM back over a local HTTP server, the read side of kage pack --format zim.
  • An optional native-window viewer. Built with -tags webview, kage open and a packed binary show the site in a real window backed by the operating system's WebView instead of a browser tab. The default build stays pure Go and opens the browser, so the release pipeline is unchanged.
  • A pure-Go zim package that reads and writes the ZIM format: a fixed header, MIME and pointer lists, zstd or stored clusters, redirects, and a trailing MD5.

v0.1.0

The first release. kage clones a live website into a self-contained folder you can browse offline, with every script stripped out.

  • kage clone <url> renders each page in headless Chrome, strips all JavaScript, and localises CSS, images, and fonts to relative paths.
  • kage serve [dir] previews a cloned folder over a local file server.
  • Idempotent and resumable. Each page is keyed by the file it writes, so a page reached over http and https, or as /index.html versus /, is fetched once. Re-running resumes; --refresh re-renders in place; --force starts clean.
  • Polite by default. Honours robots.txt, seeds from sitemap.xml, scopes to the seed host, and runs three parallel worker tiers.
  • Packaged everywhere. Archives, .deb/.rpm/.apk, a multi-arch GHCR image with Chromium bundled, checksums, SBOMs, and a cosign signature.
