* fixes #323 aio's iov may be reusedGarrett D'Amore2018-03-30
|
* fixes #322 epoll implementation is racyGarrett D'Amore2018-03-30
| | | | | This uses numeric identifiers and an idhash table to make sure that the values we get back are still use.
* fixes #315 WebSocket message handling errorsGarrett D'Amore2018-03-30
| | | | | This also gives a performance benefit to WebSocket, by making the completion logic run synchronously.

* fixes #317 TLS, TCP, and IPC should support multiple outstanding opsGarrett D'Amore2018-03-30
| | | | | | | | | | | | | | | | | | | | | | | | fixes #22 Consider using synchronous completions sometimes Transport improvements for IPC, TCP, and TLS. This change does three things. First it permits multiple outstanding receives or sends on the transport. This change is being made to accomodate some other changes in the protocols where it might be advantageous to post send or receives directly against the transport pipe without going through another level of indirection. Second, it changes the normal completions to be performed synchronously. This translates into a rather major performance improvement, reducing latency by some 27%, and thereby improving performance altogether. (This elminates two extra context switches per transaction!) FInally, we can save some extra checks and conditions because we know that completions cannot happen if we don't have a pending operation (we no longer complete out of sequence), and we only call the dosend operation when we have something to send. This can eliminate some pipeline stalls.

* Add documentation for supplemental functions.Garrett D'Amore2018-03-22
| | | | | | This includes platform portability stuff like mutexes and threads, etc. While here we fixed a problem with nng_opts_parse and we addressed the type of the platform API.
* fixes #301 String option handling for getoptGarrett D'Amore2018-03-20

* fixes #296 Typed options should validate option typeGarrett D'Amore2018-03-20
| | | | | | | | | | | | | fixes #302 nng_dialer/listener/pipe_getopt_sockaddr desired This adds plumbing to pass and check the type of options all the way through. NNG_ZT_OPT_ORBIT is type UINT64, but you can use the untyped form to pass two of them if needed. No typed access for retrieving strings yet. I think this should allocate a pointer and copy that out, but that's for later.
* Fixes issues found by (and submitted by) @nonnenmacher when workingVincent Nonnenmacher2018-03-19
| | | | | | | on a python wrapper (cffi). Mostly this is fixing inconsistencies in our public API and the actual implementation.

* fixes #295 boolean options should use C99 bool typeGarrett D'Amore2018-03-18
| | | | | | | | | | | fixes #275 nng_pipe_getopt_ptr() missing? fixes #285 nng_setopt_ptr MIS fixes #297 nng_listener/dialer_close does not validate mode This change adds some missing APIs, and changes others. In particular, certain options are now of type bool, with size of just one. This is a *breaking* change for code that uses those options -- NNG_OPT_RAW, NNG_OPT_PAIR1_POLY, NNG_OPT_TLS_VERIFIED.
* fixes #287 remove NNG_OPT_DOMAIN, NNG_OPT_PROTOCOL, and NNG_OPT_TRANSPORTGarrett D'Amore2018-03-17
| | | | | While here we documented that certain options are not supported in the compatibility layer.

* nng_sleep_aio should honor aio timeout.Garrett D'Amore2018-03-12
| | | | | | | | | | | | | | The first problem was that using nng_sleep_aio was found to reset the timeout, and this caused subsequent operations to start failing with timeouts when reusing the AIO for other operations. The second thing is that we think it would be nicer if the presence of real aio timeouts were still honored, so that if the timeout is shorter than the sleep time, then we get back an NNG_ETIMEDOUT like every other operation, and we get back a 0 if the logical sleep operation completes normally.

* fixes #269 nngcat unreliable with ZeroTier transportGarrett D'Amore2018-03-07
| | | | | | | | | | | | | | | | | | | | This does a few things. First it closes a case where a dropped message could prevent subsequent connection attempts from getting through. Second, it changes the rate at which we retry, and the timeout, to be a lot more aggressive when attempting to establish a connection. We retry every 500 ms, for up to 2 minutes, before giving up. This gives a lot more resilience in the face of message loss that is typical of ZeroTier in some environments when first establishing communication. Third, makes the values for the connection attempts *tunable*, so that applications can adjust for different deployment scenarios. Fourth, it includes the ability to get the UDP socket name. This was needed during some debug, and may be useful for a real UDP transport later, so we're keeping it. Finally, we added documentation for the above items.

| | | | fixes #267 zerotier transport should lock ZT_HOME
* ZeroTier timestamps are signed now.Garrett D'Amore2018-03-05
| | | | | | | The dev branch changed, and the timestamps are signed. (They are also passed around using volatiles -- probably incorrectly so, but that is not important for us, the compiler understands that volatile is meaningless when passing values by value.)
* Remove stale ZeroTier RFC, update URL and link to correct one.Garrett D'Amore2018-03-05
| | | | | | | | The primary ZeroTier RFC is in the "rfcs" repository for nanomsg, and we should remove this one because it is stale and misleading. Also, the URI format is incorrect in the header so fix that, and point to the real ZeroTier RFC.
* fixes #262 NNG_OPT_URL should be resolvedGarrett D'Amore2018-03-04
| | | | | | | | This causes TCP, TLS, and ZT endpoints to resolve any wildcards, and even IP addresses, when reporting the listen URL. The dialer URL is reported unresolved. Test cases for this are added as well, and nngcat actually reports this if --verbose is supplied.
* kqueue: add license infoLiam Staskawicz2018-03-04
|
* fixes #254 nngcat should have a --version optionGarrett D'Amore2018-03-02
| | | | | | We only add a basic --version (also -V). I'm still trying to figure out how to convince cmake to emit its compilation flags into a file where we can use them for output.

* fixes #247 nngcat needs TLS optionsGarrett D'Amore2018-03-02
| | | | | | | While here we also fixed a bug in the --file handling that we noticed while writing the TLS handling. We also fixed a warning in the core (msgqueue) for set but unused variables.
* fixes #240 nngcat is MIAGarrett D'Amore2018-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is intended to provide compatibility with, and has been tested against, legacy nanocat. There are a few differences though. At this time support for the alias names (where argv[0] is set to something like nngreq or somesuch) is missing. By default this library operations without NNG_FLAG_NONBLOCK on dial and listen, so that failures here are immediately diagnosable. (This behavior can be changed with the --async flag.) By default --pair means PAIRv1, but you can specify --pair0 or --pair1 explicitly. (There is also a --compat mode, and in that mode --pair means PAIRv0. The --compat mode also turns on NNG_FLAG_NONBLOCK by default.) The "quoted" mode also quotes tabs. (Legacy nanocat did not.) It is possible to connect to *multiple* peers by using the --dial or --listen (or similar) options multiple times. Shorthands can be used for long options that are not ambiguous. For example, --surv can be used to mean surveyor, but --re is invalid because it can mean req, rep, or respondent. We assume you have a reasonable standard C environment. This won't work in embedded environments without support for FILE *. TLS options are missing but to be added soon. A man page is still to be written.
* Windows IPC connection timer still thinks its usec.Garrett D'Amore2018-02-26
| | | | | | We changed the timers to use msec granularity, but we missed this one. The result is that in certain code flows the IPC connection times can look quite long -- with weird 10 sec stalls.
* Hang in concurrent IPC connection close.Garrett D'Amore2018-02-26
| | | | | | ConnectNamedPipe can return ERROR_PIPE_CONNECTED, and does not enqueue a completion packet if it does. So we need to handle that specially.
* Move compatibility header so that <nanomsg/nn.h> works.Garrett D'Amore2018-02-23
| | | | | | Basically, we have moved the compat stuff into a separate directory. Compatibility layer users will have to update their compile flags, but should be able to avoid changing any *source* files with this change.
* Add nng_opts_parse() API for handling command line options.Garrett D'Amore2018-02-22
| | | | | | | | | | | We have implemented this alternative to getopt() so that we can create nngcat. The reason we did not just use getopt() is that getopt() does not understand long options (which nanocat uses, and we want to preserve for compatibility) and getopt() is not available on Windows (and possibly other non-POSIX platforms.) This function handles long and short options, but does not have support for option clustering. It also is threadsafe & reentrant, unlike getopt.
* Modularize HTTP headers somewhat.Garrett D'Amore2018-02-21
| | | | | | We move the HTTP definitions out of the core nng.h and into a supplemental header. Most of this change was trivial updates to all of the HTTP related manual pages.
* CMake & CPack improvements.Garrett D'Amore2018-02-21
| | | | | | | | | These are incremental updates... we avoid using install() in the subdirectories, so that we can adapt properly to them in the single parent directory. We have started some of the work to improve support for CPack. This is still not yet done, but work in progress.
* Fixes for POSIX pollq structure.Garrett D'Amore2018-02-21
| | | | | | | | | | | | | | It was possible for pollq arm to be called on a node that was removed in some circumstances -- particularly and ep that was closed in the callback. While here, lets use normal booleans for closed state, and only call the arm function (which is not free -- typicall it involves a mutex and may even involve a system call) if we are going to arm some events. We also initialize these things properly, and clean up a stale comment. This work is done to faciliate the kqueue work by @liamstask.
* Introduce 'porting layer' Public API.Garrett D'Amore2018-02-20
| | | | | | | 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.
* Simply posix pollq architecture somewhat.Garrett D'Amore2018-02-15
| | | | | | | | | | This change is being made to facilitate the work done for the kqueue port. We have created two new functions, nni_posix_pollq_init and nni_posix_pollq_fini, which can be used when creating or destroying the pollq nodes. Then nodes are *added* and *removed* from the pollq structure with nni_posix_pollq_add and nni_posix_pollq_remove. The add function in particular MUST NEVER be called unless the node has a valid file descriptor.
* fixes #234 Investigate enabling more verbose compiler warningsGarrett D'Amore2018-02-14
| | | | | | | 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.
* Backout #224 Does not work in CI, and breaks legacy compatibility.Garrett D'Amore2018-02-08
| | | | | | | It turns out that at least on some systems, the CreateNamedPipeW does not behave as we'd expect. Furthermore, using the Unicode variants seems have a negative impact on compatibility with legacy nanomsg.
* fixes #171 Refactor aio to use generic data fieldsGarrett D'Amore2018-02-08
| | | | | | | | This addresses the use of the pipe special field, and eliminates it. The message APIs (recvmsg, sendmsg) need to be updated as well still, but I want to handle that as part of a separate issue. While here we fixed various compiler warnings, etc.
* fixes #224 Windows pipe name restrictions, unicodeGarrett D'Amore2018-02-07
| | | | While here, we cleaned up a few other unused variables in the HTTP code.
