annotate src/os/unix/ngx_recv.c @ 5267:13c006f0c40e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Events: honor NGX_USE_GREEDY_EVENT when kqueue support is enabled. Currently this flag is needed for epoll and rtsig, and though these methods usually present on different platforms than kqueue, nginx can be compiled to support all of them.
