Requests that hit a connection limit used to wait inside their worker,
polling every 10 ms, and an async request's timeout included that wait.
On a page with many resources from one origin, later requests timed out
while queued, and waiting requests tied up shared thread-pool workers
that other origins needed.
Connection queue:
- Serve blocking and async requests from one first-come, first-served
queue per pool. Requests waiting on one origin's limit never block
requests to other origins.
- In shared thread-pool mode, an async request runs on a worker only
after it has been granted a connection. Grants are handed to the
executor from a service thread, never from the thread releasing a
connection, which could be inside the executor's own lock.
- Requests hold their executor only weakly, so a request can never be
the last owner of the thread pool running it.
- Start an async request's timeout once it holds a connection. A
blocking call's timeout still covers the wait plus the transfer, and
a resumed download keeps its deadline across the HEAD probe.
- Wait on a condition variable instead of polling. Cancelling by ID,
shutdown() and Pool::close() release queued requests immediately.
- Let running requests and blocking callers take over a slot reserved
for queued work that has not started; that work queues again, first
in line. Without this, a redirect, retry or resumed download on a
busy executor could wait forever on slots reserved behind it.
- When queued work starts, switch to a connection that went idle while
it waited, instead of opening a new one.
- Replace an idle connection the server has closed in place, keeping
its slot.
Process-wide limit and idle expiry:
- Limit open sockets across all pools with
Http::setMaxOpenConnections() (default 256). At the limit, close the
least recently used idle socket in any pool, then a socket held for
queued work, and only wait while every socket is in active use.
- Wake waiters on the limit when a socket goes idle, and recheck a
change counter so a wake-up just before waiting is never missed.
- Only inspect a socket for reclaim once its connection is known to be
idle or reserved, never while a request is using it.
- Close idle connections from a background timer when idleTimeout
elapses, instead of only when a connection is next requested in the
same pool.
- The budget and its service thread are intentionally never destroyed,
so the thread is never joined during static destruction, which would
deadlock under the Windows loader lock.
Shutdown:
- Add Http::cancelAllRequests(), which cancels every queued and running
request in every pool and closes idle connections. A per-pool
generation counter makes running requests stop at their next check,
and the pools stay usable afterwards.
- Add Http::waitForConnectionsToClose().
- Engine cancels all requests as it starts shutting down. Once its
windows are closed, it waits up to 100 ms for sockets to close before
ending TLS.
- Check for cancellation every 25 ms instead of 100 ms while reading, so
requests stop within that wait.
TLS:
- SSLSocket::end() now waits while TLS sockets exist: the last socket
destroyed releases the backend, and a socket created in the meantime
keeps it.
- Set up the backend and register a new socket a
lock, so a concurrent end() cannot release the backend in between.
- Add SSLSocket::isInitialized() and a testing h
socket construction.
Replace thread-local connections with owned pools shared across workers.
Bound total and per-origin connections, expire idle sockets, and check
idle connections before reuse. Retry safe requests after stale-connection
races without replaying POST requests.
Fix response framing, chunk trailers, decompression completion, empty
compressed bodies, and handling of bytes beyond completed responses.
Give each WebResourceCache partition its own transport, preserving
connections across navigation and shared tabs. Close session transports
without blocking the UI thread. This substantially improves browsing
performance in the ui_html example.
Preserve every Set-Cookie field and attribute redirect cookies to the
client that received the response. Prevent rejected redirects from
assigning cookies to their destination.
Add regression coverage for pooling, framing, cancellation, TLS policy
isolation, browser sessions, and redirect cookie attribution

standalone UICalendar, with XML/CSS registration and data binding.
- Support segmented keyboard editing, numeric entry, ISO paste, configurable
steps, bounds, empty values and independent seconds/milliseconds display.
Default time display to hours and minutes while preserving stored precision.
- Add day/month/year calendar navigation and a combined date-time popup with
time steppers, live configuration updates and scoped event connections.
- Add Breeze and fallback theme styles with CSS-defined SVG icons, dp sizing,
font-aware calendar dimensions and muted read-only/disabled controls.
- Map HTML date, time and datetime-local inputs to native controls with strict
value sanitization, min/max/step/required/readonly/disabled handling,
constraint validation and normalized form serialization.
- Provide private light HTML control defaults and intrinsic temporal sizing;
prevent author CSS from styling anonymous implementation parts.
- Share popup placement and visibility helpers across pickers, dropdowns and
trigger/cursor menus while retaining cascading-menu placement rules.
- Fix fractional grid wrapping and input cursor bubbling over child buttons;
notify and refresh styles when editing permission changes.

- Restore preview tabs between sessions and preserve live editor binding
and unsaved source content when navigating back.
- Refresh the README around eepp's GUI framework and document the new APIs.
- Remove the fixed Markdown code font size and add regression coverage
- Clamp selection coordinates independently so horizontal dragging preserves
the selected row. Use the mouse event's Y coordinate against the terminal's
vertical bounds, including padding, and retain unclamped coordinates during
periodic updates outside the window.
eepp framework:
- Add shared cookie jars to UISceneNode and UIWebView, plus versioned
CookieManager persistence, domain clearing, and locking in hasCookie().
- Follow HTTP 303 redirects and merge same-host redirect cookies as
name/value pairs without forwarding Set-Cookie attributes.
- Include Cookie headers in document cache keys while preserving static
resource reuse as cookies change.
- Submit HTML forms with an empty action to the current document URL.
- Extend NavigationRequest with source, mouse buttons, modifiers, and
navigation target; anchors forward this context to the scene.

and explicit new-tab requests, with current-view fallback if unhandled.
- Install the WebView navigation interceptor during construction.
- Dispatch middle clicks to the hovered node without moving keyboard focus.
- Add the clicked target to ContextMenuEvent so applications can extend
context menus through existing events.
- Parse HTML titles, emit TitleEvent, and fix onTitleChanged's payload cast.
- Load declared favicons through the shared image cache, emit
OnFaviconChanged, and ignore responses from superseded navigation.
- Add optional UITabWidgetSplitter tab-bar visibility while split;
keep it disabled by default and respect explicitly hidden tab bars.
- Add Space/Shift+Space scrolling and viewport-sized Page Up/Down steps
to UIScrollView, shared by WebView and Markdown content.

- Support validated left, middle, and right clicks in the inspector
server and Python client.
ui_html example:
- Use UITabWidgetSplitter for tabs and user-controlled splits.

between sessions and open new tabs blank.
- Add Inspect, Clear Domain Cookies, Clear All Cookies, and contextual
Open Link in New Tab actions through menu event subscriptions.
- Open requested links in background tabs and synchronize navigation UI.
- Use document titles and 16dp favicons for tabs, cap width at 200dp,
and truncate long titles with ellipsis.
- Enable tab-bar visibility across split panes.
- Fixed: the selection rectangle now uses the visible password symbols instead of the original text.
Update HTML compatibility and inspector documentation and add regression
coverage for persistence, redirects, cache isolation, navigation, menus,
titles, favicons, password colors, split visibility, and scrolling.
Add guides for native UI authoring, layouts, application CSS, and HTML
compatibility. Update the CSS reference, rename article files consistently,
and point README links to the local guides.
