Sharing a mail folder does nothing. `Mailbox/set` takes the `shareWith`
map, `Mailbox/get` reads it back, and the folder never appears for the
account it was shared with -- confirmed on the live 0.16.19 with a folder
shared read-only to another account on the same server, which never saw
it. Stalwart's sharing documentation lists calendars, address books and
file storage; mail folders are not among them. Nothing anywhere reports a
failure, so a client that trusts what it reads back shows the share as
live for ever, which is what happened.
The entry point is withdrawn. Address book sharing goes with it on a
report that it behaved the same way -- not reproduced, and contradicted
by Stalwart's own docs, so that one is expected back; it is out because
offering a share nobody can verify was worse than the gap. Files and
calendars are untouched.
Removing a share was impossible, for a reason worth writing down. The
dialog rendered the list of who a thing was shared with *inside* the
branch that runs when the directory has principals to offer. A server
with `allowDirectoryQueries` off returns none -- that is the default, and
it is how these shares came to be made in the first place -- so the
dialog showed one line of hint and nothing else. The share was there, and
there was no way to see it, let alone remove it. The list is now rendered
whatever the directory says; only the control for adding somebody new
depends on having somebody to add.
So the withdrawn entry points do not strand what they created: a folder
or book already shared still offers "Stop sharing", which is the one
thing you want when the share is invisible everywhere else.
The API was never the problem, which is worth recording since it was the
first guess: `shareWith: null` is accepted and clears the map, tested
against the live server on the stuck folder, which is now unshared.
Calendars and address books have been shareable since JMAP Sharing went
in; Files never was, though Stalwart treats file storage as a first-class
thing to share and ihasmail has carried the types for it all along.
`FilesRights` and `FileNode.shareWith` were already declared -- what was
missing was asking for the property, offering the dialog, and saying so
in the list.
Checked against the live 0.16.19 first, read-only, because building a
picker against a mock that agrees with you proves nothing:
- `FileNode/get` returns `shareWith`, and `myRights` carries all six
rights, `mayShare` among them and true on one's own nodes. So the
menu entry has a real right to gate on -- unlike folder sharing,
which is offered ungated because `MailboxRights` has no such right
- `Principal/query` answers now that `allowDirectoryQueries` is on:
six individuals, no groups
- `ShareNotification/get` is implemented, which is worth knowing for
later; nothing here reads it yet
The editor preset grants read, add files and edit contents, and stops
there. Rename and delete stay with whoever shared the folder: someone
given a folder to work in should not be able to rename the thing they
were given, or delete it out from under the person who shared it. Both
are still there to tick by hand.
One finding is worth a test of its own, and has one. Stalwart answers
`shareWith` as `{}` for a node shared with nobody, not `null` -- every
unshared node in a live account came back that way. A truthiness test on
the property is therefore true for every node the server has ever
returned, and the badge driven by it would report the whole account as
shared while being, technically, about the right property. `isShared`
counts keys, and the test says why.
Verified against the mock end to end: sharing Documents with a principal
as Editor persists `mayRead`, `mayAddChildren` and `mayModifyContent` and
nothing else, the badge appears on that folder and not on the file beside
it, and re-opening the dialog shows the saved rights rather than an empty
form -- which is what proves `fileNodeProps` is really asking for the
property.
"Send failed: Invalid property or value." is Stalwart's description for
invalidProperties, and on its own it says nothing about what to fix. The
SetError also carries a `properties` array naming the offending fields, which
every call site was discarding.
setErrorMessage appends them, and the 35 places that surfaced a SetError -
send, save draft, mailboxes, calendars, contacts, sieve, files, signature
images, sharing - now go through it.
