* Reduce socket/pipe private data coupling.Garrett D'Amore2017-03-19
|

|
* Eliminate per-socket workers.Garrett D'Amore2017-03-10
|
* Good-bye reaper thread.Garrett D'Amore2017-03-10
|
* Start of close related race fixes. Scalability test.Garrett D'Amore2017-03-10
|
* Pipeline protocol now entirely callback driven.Garrett D'Amore2017-03-04
|
* Add device support & testing. Bus semantic fix.Garrett D'Amore2017-01-27
| | | | | | | | | | | This adds nn_device and nng_device. There were some internal changes required to fix shutdown / close issues. Note that we shut down the sockets when exiting from device -- this is required to make both threads see the failure and bail, since we are not using a single event loop. I also noticed that the bus protocol had a bug where it would send messages back to the originator. This was specifically tested for in the compat_device test, and we have fixed it.
* Add endpoint tuning of maxrcv size. Fix cmsg API.Garrett D'Amore2017-01-24
| | | | | | | | | | | | | | The CMSG handling was completely borked. This is fixed now, and we stash the SP header size (ugh) in the CMSG contents to match what nanomsg does. We now pass the cmsg validation test. We also fixed handling of certain endpoint-related options, so that endpoints can get options from the socket at initialization time. This required a minor change to the transport API for endpoints. Finally, we fixed a critical fault in the REP handling of RAW sockets, which caused them to always return NNG_ESTATE in all cases. It should now honor the actual socket option.
* Implement reconnect timer including backoff.Garrett D'Amore2017-01-24
| | | | This allows us to enable the last test case for compat_reqrep.
* Initial start of compat layer with bind, connect, etc. Untested.Garrett D'Amore2017-01-22
|
* Event notification via pollable FDs verified working.Garrett D'Amore2017-01-22
|
* Adds NNG_OPT_SENDFD and NNG_OPT_RECVFD socket options (untested).Garrett D'Amore2017-01-21
|
* Fix leaks in bus, socket leaks, tighten up close-side refcnting.Garrett D'Amore2017-01-21
| | | | | | | | | | | | | | This does a few things. First it closes some preexisting leaks. Second it tightens the overall close logic so that we automatically discard idhash resources (while keeping numeric values for next id etc. around) when the last socket is closed. This then eliminates the need for applications to ever explicitly terminate resources. It turns out platform-specific resources established at nni_init() time might still be leaked, but it's also the case that we now no longer dynamically allocate anything at platform initialization time. (This presumes that the platform doesn't do so under the hood when creating critical sections or mutexes for example.)
* Resolve deadlock during close.Garrett D'Amore2017-01-21
|
* fixes #18 Sockets should be uint32_t's (handles) not pointers.Garrett D'Amore2017-01-20
|
* Reduce lock contention and simplify logic for endpoint creation.Garrett D'Amore2017-01-18
|
* Reaper exits too soon, leaking bits.Garrett D'Amore2017-01-18
|
* Fix leaking notify structs.Garrett D'Amore2017-01-18
|
* Pipe IDs are now tracked on global ID hashes.Garrett D'Amore2017-01-17
|
* Pipe IDs are now tracked by hash table for performance.Garrett D'Amore2017-01-17
| | | | | This gives a better idea of pipe ID uniqueness, and is a step towards conversion of the API to use IDs instead of pointers.
* External event API for send/recv implemented.Garrett D'Amore2017-01-16
| | | | | | This was the main blocker, I think, for the nanomsg legacy compat shim. Now that we have this, it should be relatively straight-forward to implement the legacy nanomsg API, including the SENDFD, RECVFD thing.
* Recv/Send event plumbing implemented (msgqueue and up).Garrett D'Amore2017-01-16
| | | | | | | | This change provides for a private callback in the message queues, which can be used to notify the socket, and which than arranges for the appropriate event thread to run. Upper layer hooks to access this still need to be written.
* Start of event framework.Garrett D'Amore2017-01-16
| | | | | | | | | | This compiles correctly, but doesn't actually deliver events yet. As part of this, I've made most of the initializables in nng safe to tear-down if uninitialized (or set to zero e.g. via calloc). This makes it loads easier to write the teardown on error code, since I can deinit everything, without worrying about which things have been initialized and which have not.
* Various complaints found in AppVeyor build.Garrett D'Amore2017-01-16
|
* Move to generic socket & pipe workers, and up to 4 each.Garrett D'Amore2017-01-08
| | | | | This should eliminate all need for protocols to do their own thread management tasks.
* More close race fixing.Garrett D'Amore2017-01-07
| | | | | Don't drop the lock in sock_close while holding the pipe reference. I'm pretty sure this is responsible for the use-after-free race.
* Clean up sender/recver threads.Garrett D'Amore2017-01-07
|
* Uncrustify fix for last.Garrett D'Amore2017-01-07
|
* Simplify locking for protocols.Garrett D'Amore2017-01-07
| | | | | | | | | In an attempt to simplify the protocol implementation, and hopefully track down a close related race, we've made it so that most protocols need not worry about locks, and can access the socket lock if they do need a lock. They also let the socket manage their workers, for the most part. (The req protocol is special, since it needs a top level work distributor, *and* a resender.)
* Change a bunch of copyrights to 2017 for work done since the 1st.Garrett D'Amore2017-01-05
|
* Add nng_shutdown() for sockets to help avoid close race.Garrett D'Amore2017-01-05
| | | | Also we added a two phase shutdown for threads.
* Begin testing REQ/REP.Garrett D'Amore2017-01-02
|
* Protocol initialization restructuring.Garrett D'Amore2017-01-02
|
* Endpoint renaming.Garrett D'Amore2017-01-02
|
* Transport renaming phase 1.Garrett D'Amore2017-01-02
|
* Rename nni_socket to nni_sock.Garrett D'Amore2017-01-02
|
* Change msgqueue -> msgq.Garrett D'Amore2017-01-02
|
* Use new NNI_ALLOC_STRUCT macro. nni_msg_dup copies options too.Garrett D'Amore2017-01-02
|
* Final purge of old threading & synch stuff.Garrett D'Amore2017-01-01
|
* Endpoint uses single thread.Garrett D'Amore2017-01-01
|
* Socket reaper uses new-thread.Garrett D'Amore2017-01-01
|
* Pipe simplifications for thread management.Garrett D'Amore2017-01-01
| | | | | | | This may also address a race in closing down pipes. Now pipes are always registered with the socket. They also always have both a sender and receiver thread. If the protocol doesn't need one or the other, the stock thread just exits early.
* Free our per socket message queues.Garrett D'Amore2016-12-31
|
* More use after free.Garrett D'Amore2016-12-31
|
* Close & destroy endpoints in a single operation.Garrett D'Amore2016-12-31
|
* Factor out repeated protocol code into common.Garrett D'Amore2016-12-29
|
* Move option helpers to their own file.Garrett D'Amore2016-12-29
|
* Pipe ID calculations & socket error functions.Garrett D'Amore2016-12-28
| | | | | | | | | | | The use of platform_next_id was a bit off, because it could give back pipe IDs that were too large (the high order bit must be clear), and in very long running applications serving many connections, the IDs could wrap and lead to duplicates. Also we have added functions to set the recverr or senderr values, which can be used by protocols -- either during initialization, or during filters. (REQ uses this for example.)
* Start of REQ protocol. Still need hook handling and resender.Garrett D'Amore2016-12-28
|
* Send and receive now work.Garrett D'Amore2016-12-27
| | | | | | This fixes a few core issues, and improves readability for the message queue code as well. inproc delivery of messages works now.
