2fc35ef6bd stats: move to pt and improve presentation 2019-08-12 06:18:04 +01:00

498a4e2bd7 sul: all timed objects use a single pt sul list
wsi timeout, wsi hrtimer, sequencer timeout and vh-protocol timer
all now participate on a single sorted us list.

The whole idea of polling wakes is thrown out, poll waits ignore the
timeout field and always use infinite timeouts.

Introduce a public api that can schedule its own callback from the event
loop with us resolution (usually ms is all the platform can do).

Upgrade timeouts and sequencer timeouts to also be able to use us resolution.

Introduce a prepared fakewsi in the pt, so we don't have to allocate
one on the heap when we need it.

Directly handle vh-protocol timer if LWS_MAX_SMP == 1

b318877cd9 adopt: allow associated accepted vhost connections to specific role
Normalize the vhost options around optionally handling noncompliant
traffic at the listening socket for both non-tls and tls cases.

By default everything is as before.

However it's now possible to tell the vhost to allow noncompliant
connects to fall back to a specific role and protocol, both set
by name in the vhost creation info struct.

The original vhost flags allowing http redirect to https and
direct http serving from https server (which is a security
downgrade if enabled) are cleaned up and tested.

A minimal example minimal-raw-fallback-http-server is added with
switches to confirm operation of all the valid possibilities (see
the readme on that).

ac3bd36c60 vhost_destroy: use vhost wsi reference counting to trigger destroy
This changes the vhost destroy flow to only hand off the listen
socket if another vhost sharing it, and mark the vhost as
being_destroyed.

Each tsi calls lws_check_deferred_free() once a second, if it sees
any vhost being_destroyed there, it closes all wsi on its tsi on
the same vhost, one time.

As the wsi on the vhost complete close (ie, after libuv async close
if on libuv event loop), they decrement a reference count for all
wsi open on the vhost.  The tsi who closes the last one then
completes the destroy flow for the vhost itself... it's random
which tsi completes the vhost destroy but since there are no
wsi left on the vhost, and it holds the context lock, nothing
can conflict.

The advantage of this is that owning tsi do the close for wsi
that are bound to the vhost under destruction, at a time when
they are guaranteed to be idle for service, and they do it with
both vhost and context locks owned, so no other service thread
can conflict for stuff protected by those either.

For the situation the user code may have allocations attached to
the vhost, this adds args to lws_vhost_destroy() to allow destroying
the user allocations just before the vhost is freed.

bce8cca042 refactor: also migrate tls to the ops struct and private.h pattern
Several new ops are planned for tls... so better to bite the bullet and
clean it out to the same level as roles + event-libs first.

Also adds a new travis target "mbedtls" and all the tests except
autobahn against mbedtls build.

aa816e98a9 alpn: assemble defaults from roles and allow override
Since new roles may be incompatible with http, add support for
alpn names at the role struct, automatic generation of the
default list of alpn names that servers advertise, and the
ability to override the used alpn names per-vhost and per-
client connection.

This not only lets you modulate visibility or use of h2,
but also enables vhosts that only offer non-http roles,
as well as restricting http role vhosts to only alpn
identifiers related to http roles.
