This only does it for rep, but it also has changes that should increase
the overall test coverage for the REP protocol

fixes #1035 Convey is awkward -- consider acutest.h
This represents a rather large effort towards cleaning up our
testing and optional configuration infrastructure.
A separate test library is built by default, which is static, and
includes some useful utilities design to make it easier to write
shorter and more robust (not timing dependent) tests. This also means
that we can cover pretty nearly all the tests (protocols etc.) in
every case, even if the shipped image will be minimized.
Subsystems which are optional can now use a few new macros to configure
what they need see nng_sources_if, nng_headers_if, and nng_defines_if.
This goes a long way to making the distributed CMakefiles a lot simpler.
Additionally, tests for different parts of the tree can now be located
outside of the tests/ tree, so that they can be placed next to the code
that they are testing.
Beyond the enabling work, the work has only begun, but these changes
have resolved the most often failing tests for Darwin in the cloud.

There is quite some package loss, which I will pursue
later (in nng / zerotier). For now it helps to tune these settings
to keep the peer relations.

This also eliminates the enforcement of NNG_OPT_RECVMAXSZ for inproc,
which never really made much sense. This helps inproc go faster.
While here, also clean up the entry point for protocols to support
a drain option, since we don't use that anywhere.

fixes #698 Need TCP stats
fixes #699 Need IPC stats
fixes #701 Need TLS stats
This commit addresses a problem when negotiating using one of the stream
based negotiation APIs -- a slow or misbehaving peer can prevent well
behaved ones from establishing a connection. The fix is a fairly
significant change in how these transports link up, and it does rely
on the fact that the socket only has a single accept() or connect()
pending at a time (on a given endpoint that is).
While here, we have completely revamped the way transport statistics are
done, offering a standard API for collecting these statistics.
Unfortunately, this completely borks the statistics for inproc. As we
are planning to change the way inproc works soon, in order to provide
more control and work on performance fixes for the message queue, we feel
this is an acceptable trade-off. Furthermore, almost nobody uses inproc
for anything, and even fewer people are making use of the statistics
at this time.

We also have made some support changes, including new APIs for printing
URLs, and some improvements to the NNG_OPT_URL to make use of this new
property.

This is a major change, and includes changes to use a polymorphic
stream API for all transports. There have been related bugs fixed
along the way. Additionally the man pages have changed.
The old non-polymorphic APIs are removed now. This is a breaking
change, but the old APIs were never part of any released public API.

This changes much of the internal API for TCP option handling, and
includes hooks for some of this in various consumers. Note that the
consumers still need to have additional work done to complete them,
which will be part of providing public "raw" TLS and WebSocket APIs.
We would also like to finish addressing the call sites of
nni_tcp_listener_start() that assume the sockaddr is modified --
it would be superior to use the NNG_OPT_LOCADDR option. Thaat will be
addressed in a follow up PR.

Some more changes to use nni_type instead of nni_opt_type
are included as well.
|
| |
|
|
|

This also makes some smaller related changes to use the new
nni_type instead of nni_opt_type.

This change makes embedding nng + nggpp (or other projects depending on
nng) in cmake easier. The header files are moved to a separate include
directory. This also makes installation of the headers easier, and
allows clearer identification of private vs public heade files.
Some additional cleanups were performed by @gedamore, but the main
credit for this change belongs with @gregorburger.

This is a significant refactor of the library configuration.
We use the modern package configuration helper, with a template
script that also does the find_package dance for any of our
dependencies.
We also have restructured the code so that most protocols and
transports have their configuration isolated to their own CMakeLists
file, reducing the size of the global CMakeLists file.

These options are undocumented -- for now. We need to get some
experience with them to ensure that they are worth keeping.

While the fragment size itself fits within 16-bits, when we do math
on it (such as multiplying by a fragment count), we may need to calculate
values that exceed 16-bits (e.g. 1MB). Therefore we should treat this
as a size_t, but cast it down to 16-bits only when we write it out to
the packet field.

This changes the code to make use of a different project we have
created (libzerotiercore) that is "CMake clean". This should make
using and configuring this code *much* better. It may also have the
benefit of making this configuration work better for Windows systems.

This reverts 707, and provides a correct fix for busted
port discrimination. It also has a few minor cleanups
and reduces the listen timeout to 10 seconds.

This introduces new public APIs for obtaining statistics,
and adds some generic stats for dialers, listeners, pipes, and
sockets. Also added are stats for inproc and pairv1 protocol.
The other protocols and transports will have stats added
incrementally as time goes on.
A simple test program, and man pages are provided for this.
Start by looking at nng_stat(5).
Statistics does have some impact, and they can be disabled by
using the advanced NNG_ENABLE_STATS (setting it to OFF, it's
ON by default) if you need to build a minimized configuration.

While here we separate out the dialer and listener options, so
that options for tuning connection are only available for listeners.

This both makes new functions available to the core,
and addresses a bug which would have prevented building the
ZeroTier transport on Windows.

This also fixes a leaked TCP connection on a failure path, which we
noticed while working this change.

This changes the signature of the aio cancellation routines
to take the argument for cancellation directly, so we do not
need to lookup the argument using the nni_aio_get_prov_data.
We should probably consider eliminating nni_aio_get_prov_data,
and co, and changing the prov_extra to reflect prov_data. Later.

fixes #615 IPC close on Windows leaves handle open
This reintroduces the code to eradicate the separate transport
start function for IPC, as a incremental step towards the full
fix for 599 and 208. It also addresses 615, by including revised
logic for the handling of close.
