From 0586599fc6020df996c4278230eeea99b9d070cb Mon Sep 17 00:00:00 2001 From: Lukasz Kasprzak Date: Tue, 28 Jul 2026 14:02:54 +0200 Subject: licence: relicense MIT -> AGPL-3.0-or-later lectio was MIT, which let anyone take it closed. The concern is not people selling it -- no licence stops that, and the AGPL does not try to -- but someone building a proprietary product on it and giving nothing back. Plain GPL would leave the obvious hole open: lectio-web is a network service, and hosting is not distribution, so a modified lectio-web could be run as a paid subscription API without ever publishing a line. AGPL section 13 closes exactly that. LICENSE is the verbatim FSF text. README carries the standard notice. Section 13 requires a modified network-reachable version to PROMINENTLY offer its source to the users interacting with it, so the offer ships with the code rather than living only in a file nobody fetches: - GET /source plain text, no template or config dependency, so it answers even when something else is broken - page footers every full page (fragments render inside one) - JSON envelope "source" / "license" - iCal header X-LECTIO-SOURCE / X-LECTIO-LICENSE The feed fields are not redundant: an /api/calendar.json consumer or an .ics subscriber never loads a page, so the footer alone would miss them. config.SourceURL is the single source of truth, and says in its comment that a fork running as a service must repoint it -- an offer that leads to someone else's code is not an offer. Tests pin all of it. This is a licence obligation, not a feature, so it should fail loudly if a later change drops it. --- internal/calfeed/ical_test.go | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'internal/calfeed/ical_test.go') diff --git a/internal/calfeed/ical_test.go b/internal/calfeed/ical_test.go index fb7ee9a..215c0e3 100644 --- a/internal/calfeed/ical_test.go +++ b/internal/calfeed/ical_test.go @@ -4,6 +4,8 @@ import ( "strings" "testing" "time" + + "github.com/lukaszkasprzak/lectio/internal/config" ) func TestICalEscapeInjection(t *testing.T) { @@ -19,6 +21,22 @@ func TestICalEscapeInjection(t *testing.T) { } } +// TestICalCarriesSourceOffer pins the AGPL-3.0 ยง13 offer into the VCALENDAR +// header.
