ihasmail's notifications came from EventSource, which lives exactly as
long as a tab does -- so "desktop notifications" has always quietly
meant "while you are looking". That switch is now labelled as much, and
a second one does the thing people assumed the first one did.
Stalwart 0.16 signs Web Push with VAPID (RFC 9749) and can put the
message itself in the payload (draft-ietf-jmap-emailpush). The server
pushes straight to the browser's own push service: ihasmail's server is
not in the delivery path, there is no relay to run, and nothing beyond
the browser vendor's endpoint that Web Push requires of everyone.
Checked against the live 0.16.19 before any of this was written, because
an advertised capability is not a configured one:
- the session publishes a real applicationServerKey, so no key
generation or server configuration is needed
- PushSubscription/get answers an ordinary user rather than refusing
- emailpush is advertised, and its draft defines a filter, an ordered
properties list and an urgency -- so the payload can carry sender and
subject, and the server drops properties from the end when it will
not fit rather than failing the notification
Three things this gets right that are easy to get wrong:
- The verification handshake. A JMAP subscription delivers nothing
until the client echoes back a code the server pushed, and the
service worker cannot answer it -- no credentials in that context.
It forwards the code to a tab, or leaves it in the cache when no tab
was open to forward it to.
- Key encoding. The W3C Push API produces unpadded base64url and
Stalwart 0.16 was fixed to accept exactly that, so nothing here pads
on the way out. The VAPID key needs padding on the way *in* for
atob; getting that backwards fails at subscribe() with an opaque
error, so it lives in one named function with tests.
- Sign-out. A subscription belongs to the account, not the session.
Without tearing it down, a shared machine keeps notifying for a
mailbox nobody is signed into -- which is somebody else's mail.
The mock models the JMAP half, including refusing padded keys and
non-https endpoints, and creating subscriptions *unverified*. Delivery
cannot be mocked -- it runs through the browser vendor's real push
service -- but a mock that marked a subscription verified on creation
would let a client ship without the handshake, and the symptom in
production is "registered, and silent".
Not verified end to end: an actual notification arriving. That needs a
real browser, a real push service and real delivery, so it is live
testing or nothing.
The logo baked "ihasmail.com" into the artwork, which is the wrong
identity for a project that is not the hosted instance -- and at the
34px the topbar renders it at, the wordmark was an illegible smudge
under a squashed cat.
logo.png, icon-512.png, icon-192.png and apple-touch-icon.png are now
the mark alone. favicon-64.png, icon-maskable.png and favicon.ico
already were, and are untouched.
Cropping needed a threshold: both source files carry a band of
near-invisible pixels (alpha 1-10) roughly 40px wide down the left
side, so a plain getbbox() crop leaves the mark sitting off-centre.
The bounding box is taken at alpha > 8 instead.
The login page had no name of its own -- it relied on the wordmark --
so it gets one as text, styled like the topbar's. Its screenshot is
retaken; the rest still show the old mark in the topbar.
Settings > General gains a "Default mail app" section that calls
registerProtocolHandler so mail links anywhere in the browser open ihasmail.
The browser owns the decision and there is no API to read it back, so the UI
says what it can: it records that we asked, offers "Ask again", shows a
Remove button where unregisterProtocolHandler exists, and points at the
browser's own settings. Unsupported browsers (Safari) and insecure contexts
get an explanation instead of a dead button.
The manifest now declares protocol_handlers for mailto, which is the route by
which an *installed* app can be offered by the operating system itself; the
UI says so and links the two ideas rather than promising a system-wide
default the page cannot grant.
Mailto parsing is now one function (parseMailto in lib/address.ts) instead of
three hand-rolled copies in AppShell and MessageView. It follows RFC 6068:
recipients from the path, the to= header or both, case-insensitive headers,
"+" as space, and tolerant of malformed escapes. That fixes Cc and Bcc being
silently dropped, and draftFromMailto escapes the body so a mailto: URL from
an untrusted page reaches the composer as text rather than markup.
