A list could leave the instance as a TREK file, which only another TREK
reads. Export now asks for a format, and GPX is the second one: the
places as waypoints, for OsmAnd, Organic Maps, a Garmin or gpx.studio.
Import takes a GPX in the same dialog as a list file. Asked for in
discussion #2301.
The GPX is written from the very list file the JSON export returns, so
what may leave the instance is still decided in one place. Name,
description and address, notes, website and category go into GPX's own
elements, where every app shows them. Labels, status, phone and the
rest travel in a TREK extension namespace, so a GPX made by TREK comes
back as the same list. A place without coordinates cannot be a
waypoint; it is left out and the export says how many were.
A GPX is read on the server, sent as text, with the XML library the
trip importer already uses. A document with a DOCTYPE is refused before
parsing, which closes both external entities and entity expansion. Size
is capped like the list file, and the element count is capped before a
tree is built. The reader only turns the GPX into a list file: the
browser previews it and imports it through the existing route, so one
contract, one transaction and one skipped counter cover both formats.
Waypoints and named route points become places; tracks and unnamed
route points are counted in the preview and not imported.
The two list-file routes get a body ceiling of twice the file limit.
The global 100 kB cap refused most real favourites files, and it
already refused list files well under the megabyte the contract allows.
POST /api/addons/collections answers with the collection itself — the
controller returns the service's `Collection` straight through, and the e2e
suite pins that shape. The client declared a `{ collection }` envelope and
read `.collection` off it, so `createCollection()` resolved `undefined` and
handed back `null` every single time.
The caller needs that id. In the list editor and its phone sheet the id is
what the cover upload and `onCreated` hang off, so creating a list with a
cover picked in the same dialog silently dropped the image, the new list was
never opened or selected afterwards, and the retry guard that exists to stop
a failed cover step from minting a duplicate was dead. The list itself still
appeared, because `loadAll()` runs first — which is why this went unnoticed.
Nothing caught it because both test layers stubbed the shape the client
believed in rather than the one the server sends: the api suite's MSW
handlers wrapped the collection in an envelope, and the store suite's mock
resolved one too. Both now answer the way the controller does, `update()`
included — its declared type was wrong for the same reason, though no caller
reads its result.
The fix is on the client. That wire shape has shipped for as long as
Collections has existed and the server e2e test pins it, so changing that
side would be the breaking one.
