In the client, add command "chat" and "chatbot". The "chat" command run client chart as before. The "chatbot" command create client for all known accounts and send N messages continuously. 2023-07-03T16:10:38Z Shulhan ms@kilabit.info 2023-07-03T15:27:30Z urn:sha1:e94de9a9b7a474c092aeccaf91bb43ecb35f6acb When the goroutine for upgrade, reader, or pinger does not receive any input from its queue after N duration, stop it. Currently, N equal to ServerOptions ReadWriteTimeout. This allow unused goroutines released back to system, minimizing resources usage. 2023-07-01T10:25:15Z Shulhan ms@kilabit.info 2023-07-01T07:46:38Z urn:sha1:7b01a3fc41b8611aa26c7d5d0f5c0f2bcd012ee0 2023-07-01T10:25:15Z Shulhan ms@kilabit.info 2023-06-30T18:34:25Z urn:sha1:b9f69e549f1ecde42f34cc2dab6437bb62c42fe6 The maximum goroutines is quarter of max queue. The new goroutine for pinger will be dispatched when no goroutine can consume the current processed connection. 2023-07-01T10:25:15Z Shulhan ms@kilabit.info 2023-06-29T14:24:44Z urn:sha1:091751a2e0e4f162454275e511a718d15ebf3886 Adding prefix provide better way to locate and debug the error in the future. 2023-07-01T10:24:30Z Shulhan ms@kilabit.info 2023-06-29T14:20:39Z urn:sha1:90203c3603bfbf01b5517fa9da49e276a506b733 Previously, the Pool's WaitRead and WaitReadEVent methods return list of file descriptor (fd) and keeps the fd in the pool. In case we want to process the returned fd concurrently, by running it in different goroutine, the next call WaitRead may return the same fd if its goroutine not fast enought to read from fd. This changes fix this issue by removing list of fd from poll and set the fd flag to blocking mode again after returning it from WaitRead or WaitReadEvent. This changes also remove the ReregisterRead and ReregisterEvent methods since it is not applicable anymore. 2023-07-01T10:23:26Z Shulhan ms@kilabit.info 2023-06-27T16:36:22Z urn:sha1:1570b3182b534c5a0a952e54531fff9769430930 The Server now dispatch a goroutine to consume event from poll reader for each client connection that is ready to read. The maximum number of goroutine is defined in ServerOptions maxGoroutineReader, which currently set to 1024. 2023-07-01T10:23:26Z Shulhan ms@kilabit.info 2023-06-26T18:59:03Z urn:sha1:1623f171f048a0580474a41832dcdf409f63c0fe The PollEvent contains file descriptor and the underlying event based on OS, unix.EpollEvent on Linux or unix.Kevent_t on BSD. The Poll interface provides two APIs to works with PollEvent, WaitReadEvents that return list of PollEvent ready for read, and ReregisterEvent to register the event back to poll (only for Linux).
