This also deprecates supplemental/util/platform.h.

None of these changes are actual security bugs, but GitHub's
scanner reports false positives at Critical severity for them.
(There are a number of complaints from that scanner, many of
which we do not necessarily agree with.)

This arranges for nng_fini to be called via atexit in the test
version of the library. It also cleans up some of the actual
tests to reduce extraneous (and in some cases incorrect) calls
to nng_fini.

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.

fixes #405 warning: newline not last character in file
This is basically a slew of related bug fixes required to make this
work on illumos. Note that the fixes are not "complete", because
more work is required to support port events given that epoll is busted
on illumos.
We also fixed a bunch of things that aren't actually "bugs" per se, but
really just warnings. Silencing them makes things better for everyone.
Apparently not all compilers are equally happy with redundant (but
otherwise identical) typedefs; we use structs in some places instead of
shorter type names to silence these complaints.
Note that IPC permissions (the mode bits on the socket vnode) are not
validated on SunOS systems. This change includes documentation to reflect
that.

This introduces portable primitives for time, random numbers,
synchronization primitives, and threading. These are somewhat
primitive (least common denominiators), but they can help with writing
portable applications, especially our own demo apps.

We enabled verbose compiler warnings, and found a lot of issues.
Some of these were even real bugs. As a bonus, we actually save
some initialization steps in the compat layer, and avoid passing
some variables we don't need.

This makes all the protocols and transports optional. All
of them except ZeroTier are enabled by default, but you can
now disable them (remove from the build) with cmake options.
The test suite is modified so that tests still run as much
as they can, but skip over things caused by missing functionality
from the library (due to configuration).
Further, the constant definitions and prototypes for functions
that are specific to transports or protocols are moved into
appropriate headers, which should be included directly by
applications wishing to use these.
We have also added and improved documentation -- all of the
transports are documented, and several more man pages for
protocols have been added. (Req/Rep and Surveyor are still
missing.)

There is now a public nng_duration type. We have also updated the
zerotier work to work with the signed int64_t's that the latst ZeroTier
dev branch is using.

This makes the APIs use string keys, and largely eliminates the use of
integer option IDs altogether. The underlying registration for options
is also now a bit richer, letting protcols and transports declare the
actual options they use, rather than calling down into each entry point
carte blanche and relying on ENOTSUP.
This code may not be as fast as the integers was, but it is more intuitive,
easier to extend, and is not on any hot code paths. (If you're diddling
options on a hot code path you're doing something wrong.)

This eliminates all the old #define's or enum values, making all
option IDs now totally dynamic, and providing well-known string
values for well-behaved applications.
We have added tests of some of these options, including lookups, and
so forth. We have also fixed a few problems; including at least
one crasher bug when the timeouts on reconnect were zero.
Protocol specific options are now handled in the protocol. We will
be moving the initialization for a few of those well known entities
to the protocol startup code, following the PAIRv1 pattern, later.
Applications must therefore not depend on the value of the integer IDs,
at least until the application has opened a socket of the appropriate
type.

Also enables creating endpoints that are idle (first part of
endpoint options API) and shutting down endpoints.

fixes #38 Make protocols "pluggable", or at least optional
This is a breaking change, as we've done away with the central
registered list of protocols, and instead demand the user call
nng_xxx_open() where xxx is a protocol name. (We did keep a
table around in the compat framework though.)
There is a nice way for protocols to plug in via
an nni_proto_open(), where they can use a generic constructor
that they use to build a protocol specific constructor (passing
their ops vector in.)

There is still a Windows mystery (and maybe not just Windows) where
nng_close() appears to hang unless some output is performed. More
testing and analysis is needed here -- but the main message exchanges
seem to work fine.

This fixes a potential nasty bug associated with the objhash table
resizing, and rewrites the scalability test to use just a single thread
handling some 2000 client sockets. This proves that the framework can
deal with vast numbers of sockets, regardless of the supported number
of operating system threads.
|
| | |
|
| |
|
|
|
| |
This should address some of the errors we've seen. Additionally,
the scalability test was a bit brittle due to too-short timeouts.
