The served main page broke its own CSS and images when the entry point
was a nested page. kage saves each page's asset links as mirror-relative
paths (../_kage/...) computed for that page's own location, but the
handler served the main page's bytes directly at /, so the browser
resolved those relative URLs against / and 404ed every one of them. A
developer.apple.com/documentation mirror landed at / with no styles.
Redirect / to the main page's canonical content path, the way the
archive's W/mainPage redirect already does, so the browser navigates to
the page's real URL and resolves its relative assets correctly. Kiwix
was unaffected because it follows that redirect itself.
* 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.
Add the v0.2.1 release notes and cut the changelog entry.
errcheck flagged six naked defer Close() calls in the pack code and its
tests. Wrap them in the same defer func() { _ = x.Close() }() form the rest
of the tree already uses.
BuildZIM walks a cloned host directory, turns every file into a content
entry with a MIME inferred from its extension, picks a main page, and adds
the standard metadata plus a mainPage redirect. state.json is skipped.
BuildBinary appends the archive to a copy of kage behind a KAGEPCK1 trailer,
and Embedded detects that trailer at startup so the binary serves itself.
Handler maps / to the main page and /path to a content entry, the same
handler the embedded viewer uses.
