Client connections can put themselves on the active client list
before they have survived the client connect process past oom4,
which can fail out without close processing.
So ensure the wsi destruction on oom4 removes it from the list.
This adds a plugin that interfaces to libjsongit2
https://warmcat.com/git/libjsongit2
to provide a per-vhost service for presenting bare git repos in a
web interface.
nonzero return from lws_http_serve() can equally be because we
hit on an ETAG and finished the serve with only the headers.
Split the return so -1 is to assertively close the stream, 1
is we didn't serve anything (eg, not found) and 0 is continuing
asynchronously to serve.
This creates a "pthread mutex with a reference count"
using gcc / clang atomic intrinsics + pthreads.
Both pt and context locks are moved to use this,
pt already had reference counting but it's new for
context.
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.
- split raw role into separate skt and file
- remove all special knowledge from the adoption
apis and migrate to core
- remove all special knowledge from client_connect
stuff, and have it discovered by iterating the
role callbacks to let those choose how to bind;
migrate to core
- retire the old deprecated client apis pre-
client_connect_info
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.
