* Events: available bytes calculation via ioctl(FIONREAD).Maxim Dounin2019-10-17
| | | | | | | | | | | | | | | | | | | | | This makes it possible to avoid looping for a long time while working with a fast enough peer when data are added to the socket buffer faster than we are able to read and process them (ticket #1431). This is basically what we already do on FreeBSD with kqueue, where information about the number of bytes in the socket buffer is returned by the kevent() call. With other event methods rev->available is now set to -1 when the socket is ready for reading. Later in ngx_recv() and ngx_recv_chain(), if full buffer is received, real number of bytes in the socket buffer is retrieved using ioctl(FIONREAD). Reading more than this number of bytes ensures that even with edge-triggered event methods the event will be triggered again, so it is safe to stop processing of the socket and switch to other connections. Using ioctl(FIONREAD) only after reading a full buffer is an optimization. With this approach we only call ioctl(FIONREAD) when there are at least two recv()/readv() calls.
* Added missing static specifiers.Eran Kornblau2017-03-02
|
* Removed NGX_OLD_THREADS from select and poll modules.Ruslan Ermilov2015-03-26
| | | | These modules can't be compiled on win32.
* Removed unix ngx_threaded and related ngx_process_changes.Ruslan Ermilov2015-03-20
|
* Thread pools implementation.Valentin Bartenev2015-03-14
|
* Renamed NGX_THREADS to NGX_OLD_THREADS because of deprecation.Ruslan Ermilov2015-03-04
| | | | It's mostly dead code and the original idea of worker threads has been rejected.
* Events: processing of posted events changed from LIFO to FIFO.Valentin Bartenev2014-09-01
| | | | | | | In theory, this can provide a bit better distribution of latencies. Also it simplifies the code, since ngx_queue_t is now used instead of custom implementation.
* Events: removed broken thread support from posted events.Valentin Bartenev2014-09-01
| | | | | It's mostly dead code. And the idea of thread support for this task has been deprecated.
