| * | Fix incorrect attempt to proceed inproc. | Garrett D'Amore | 2017-07-15 |
| | | |||
| * | Race conditions removed... TCP tests work well know. | Garrett D'Amore | 2017-07-15 |
| | | |||
| * | Some initial progress on *connect* async. | Garrett D'Amore | 2017-07-15 |
| | | | | | | | This actually is breaking at the moment, because we don't have good integration with timeouts, and there are some frustrating races with timeouts at points that can cause apparent hangs. | ||
| * | Implemented asynchronous (fully) accept. | Garrett D'Amore | 2017-07-14 |
| | | | | | | | This logic leaves a race condition in the dial side, which will be fixed with a subsequent change to convert that to fully asynchronous as well. | ||
| * | Close a race during pipe creation. | Garrett D'Amore | 2017-07-13 |
| | | |||
| * | Use the same pipe teardown in all circumstances. | Garrett D'Amore | 2017-07-13 |
| | | |||
| * | Use the same flow regardless of whether pipe start is used or not. | Garrett D'Amore | 2017-07-13 |
| | | | | | | | This means that pipe_start always succeeds, and we can guarantee that the pipe_start_cb is always executed, and in another context. This may help when we need to change the way that sockets and endpoints are associated. | ||
| * | Simplify pipe logic, going back to idhash. | Garrett D'Amore | 2017-07-13 |
| | | |||
| * | idhash has it's own lock now. | Garrett D'Amore | 2017-07-13 |
| | | |||
| * | Make idhash non-inlined (so we can add a mutex.) | Garrett D'Amore | 2017-07-13 |
| | | |||
| * | Windows implmentation of TCP is "working now". | Garrett D'Amore | 2017-07-13 |
| | | | | | | | This is only lightly tested, and I expect that there remain some race conditions. Endpoint logic in particular needs work. | ||
| * | Attempts to minimize races, remove unused nni_sock_mtx function. | Garrett D'Amore | 2017-07-12 |
| | | | | | | | We still have endpoint related races apparently; we need to examine the possibility of handling endpoints much like we do pipes, which seem to be race free. | ||
| * | Eliminate the separate wrapping structure for platform mtx and cv. | Garrett D'Amore | 2017-07-11 |
| | | |||
| * | Make better use of enums (makes clang-format happier.) | Garrett D'Amore | 2017-07-10 |
| | | |||
| * | Give up on uncrustify; switch to clang-format. | Garrett D'Amore | 2017-07-10 |
| | | |||
| * | Various cleanups of unused bits. | Garrett D'Amore | 2017-07-08 |
| | | |||
| * | SRWLocks FTW! | Garrett D'Amore | 2017-07-07 |
| | | | | | | | | | | Modern Windows (Vista and later) have light weight Slim Read/Write locks which only occupy 64 bits, and don't require any memory allocation to create. While here clean up a few more unreferenced variables found with the Microsoft compilers. | ||
| * | Start of progress on Windows. Name resolution and IOCP work begins. | Garrett D'Amore | 2017-07-07 |
| | | |||
| * | Dead code removal (stuff for removed sync transport apis.) | Garrett D'Amore | 2017-07-07 |
| | | |||
| * | TCP asynchronous working now. | Garrett D'Amore | 2017-07-07 |
| | | | | | | | | | | | | | | | | | It turns out that I had to fix a number of subtle asynchronous handling bugs, but now TCP is fully asynchronous. We need to change the high-level dial and listen interfaces to be async as well. Some of the transport APIs have changed here, and I've elected to change what we expose to consumers as endpoints into seperate dialers and listeners. Under the hood they are the same, but it turns out that its helpful to know the intended use of the endpoint at initialization time. Scalability still occasionally hangs on Linux. Investigation pending. | ||
| * | Fixes for async resolver, plus a test suite for it. | Garrett D'Amore | 2017-07-06 |
| | | |||
| * | Initial swag at asynchronous name resolution. | Garrett D'Amore | 2017-07-06 |
| | | |||
| * | Make ipc work 100% async. | Garrett D'Amore | 2017-07-05 |
| | | | | | | | | | | | | | | | | | | | The connect & accept logic for IPC is now fully asynchronous. This will serve as a straight-forward template for TCP. Note that the upper logic still uses a thread to run this "synchronously", but that will be able to be removed once the last transport (TCP) is made fully async. The unified ipcsock is also now separated, and we anticipate being able to remove the posix_sock.c logic shortly. Separating out the endpoint logic from the pipe logic helps makes things clearer, and may faciliate a day where endpoints have multiple addresses (for example with a connect() endpoint that uses a round-robin DNS list and tries to run the entire list in parallel, stopping with the first connection made.) The platform header got a little cleanup while we were here. | ||
| * | Move IPC negotiation out of connect/accept. | Garrett D'Amore | 2017-07-05 |
| | | | | | | | This prevents a slow partner from blocking new connections from being established on the server. Before this a single partner could cause the server to block waiting to complete the negotiation. | ||
| * | Return void on send & recv for transports. | Garrett D'Amore | 2017-07-05 |
| | | |||
| * | Cleanup some unused things. | Garrett D'Amore | 2017-07-05 |
| | | |||
| * | Improved routines for list management. | Garrett D'Amore | 2017-07-04 |
| | | |||
| * | Rename aio functions. Enhanced epdesc_finish. | Garrett D'Amore | 2017-07-04 |
| | | |||
| * | IPC & TCP negotiation done using aio. Remove old sync send/recv. | Garrett D'Amore | 2017-07-03 |
| | | |||
| * | inproc transport uses aio for connect/accept. | Garrett D'Amore | 2017-07-03 |
| | | |||
| * | Rename legacy connect/accept as _sync for now. | Garrett D'Amore | 2017-07-03 |
| | | |||
| * | Remove the unused infinite timeout versions of msgq. | Garrett D'Amore | 2017-07-03 |
| | | |||
| * | Delete unused msgq_notify. (We use aios instead.) | Garrett D'Amore | 2017-07-03 |
| | | |||
| * | Use common aio cancellation. | Garrett D'Amore | 2017-07-02 |
| | | |||
| * | More aio name cleanups. | Garrett D'Amore | 2017-07-02 |
| | | |||
| * | Remove the extra _aio_ part of pipe send and recv functions. | Garrett D'Amore | 2017-07-02 |
| | | |||
| * | pipe_send and recv can be void. | Garrett D'Amore | 2017-07-02 |
| | | |||
| * | Transports allocate their pipe structures during connect & accept. | Garrett D'Amore | 2017-07-02 |
| | | |||
| * | Begin work on async connect/accept for POSIX. Not referenced yet. | Garrett D'Amore | 2017-06-29 |
| | | |||
| * | Use common socket handling on POSIX (tcp done, ipc pending.) | Garrett D'Amore | 2017-06-29 |
| | | |||
| * | Pass cancel of IPC and TCP all the way down to POSIX pipedescs. | Garrett D'Amore | 2017-06-29 |
| | | |||
| * | We don't need pipe_hold or pipe_rele anymore. | Garrett D'Amore | 2017-06-28 |
| | | |||
| * | Refactor stop again, closing numerous races (thanks valgrind!) | Garrett D'Amore | 2017-06-28 |
| | | |||
| * | Clean up the pipe system (no leaks). | Garrett D'Amore | 2017-06-28 |
| | | |||
| * | Cancellation plumbing for message queues. | Garrett D'Amore | 2017-06-27 |
| | | |||
| * | Put errors go on the putq. | Garrett D'Amore | 2017-06-27 |
| | | |||
| * | Convert to POSIX polled I/O for async; start of cancelable aio. | Garrett D'Amore | 2017-06-27 |
| | | | | | | | | | | | | | | | | | | | This eliminates the two threads per pipe that were being used to provide basic I/O handling, replacing them with a single global thread for now, that uses poll and nonblocking I/O. This should lead to great scalability. The infrastructure is in place to easily expand to multiple polling worker threads. Some thought needs to be given about how to scale this to engage multiple CPUs. Horizontal scaling may also shorten the poll() lists easing C10K problem. We should look into better solutions than poll() for platforms that have them (epoll on Linux, kqueue on BSD, and event ports on illumos). Note that the file descriptors start out in blocking mode for now, but then are placed into non-blocking mode. This is because the negotiation phase is not yet callback driven, and so needs to be synchronous. | ||
| * | More race condition fixes. | Garrett D'Amore | 2017-06-26 |
| | | |||
| * | Set the expiration under lock (data race). | Garrett D'Amore | 2017-06-26 |
| | | |||
| * | Fix uninitialized use (thanks valgrind.) | Garrett D'Amore | 2017-06-26 |
