Glenn Strauss 3f7779d247 [core] restart dead piped loggers every 64 sec
(when piped logger exited too quickly after being restarted
 and when server.max-worker = 0)

Glenn Strauss 8588772caa [core] isolate fdevent subsystem
fdevent.c no longer directly uses struct server *srv
srv->srvconf.max_fds (if set) is used to set rlimits
set max_conns in server.c after fdevent_init(), which sets srv->max_fds
  using srv->srvconf.max_fds (if set) as input hint

Glenn Strauss 3cd74a16a2 [core] fdevent uses uint32_t instead of size_t 2020-07-08 19:54:29 -04:00
Glenn Strauss 010c28949c [multiple] prefer (connection *) to (srv *)
convert all log_error_write() to log_error() and pass (log_error_st *)

use con->errh in preference to srv->errh (even though currently same)

avoid passing (server *) when previously used only for logging (errh)

Glenn Strauss fce489b806 [core] fall back to accept() if accept4() EPERM (fixes #2998)
On some architectures, accept4() might result in EPERM depending
on Linux kernel and/or glibc support for accept4()

(thx alex-che)

  "accept4 returns EPERM instead of ENOSYS on some platforms"

(avoid need to translate event flags between OS and lighttpd FDEVENT_*)

Glenn Strauss f5f221eda8 [core] dispatch events from within event framework
event framework now calls interface to dispatch events rather than
itself implementing multiple interfaces for fdevent_process() to
be able to dispatch events generically.

Glenn Strauss 04d76e7afd [core] some header cleanup
provide standard types in first.h instead of base.h
provide lighttpd types in base_decls.h instead of settings.h
reduce headers exposed by headers for core data structures
  do not expose <pcre.h> or <stdlib.h> in headers
move stat_cache_entry to stat_cache.h
reduce use of "server.h" and "base.h" in headers

Glenn Strauss d400f8aac5 [core] fdevent_accept_listenfd() nonblock cloexec
fdevent_accept_listenfd() now always returns fd O_NONBLOCK O_CLOEXEC
for consistency, rather than setting elsewhere in connection_accepted()

Handle older Linux 2.6 kernels which might have accept4() in glibc,
but return ENOSYS, as accept4() was not added until Linux kernel 2.6.28.

Glenn Strauss b9df146b3c [core] non-blocking write() to piped loggers
If pipe fills and would block, then discard remaining write.
Do not block lighttpd if the logger blocks, such as if disk fills up.

Glenn Strauss 84b5064dc4 [core] discard from socket using recv MSG_TRUNC
discard from socket using recv MSG_TRUNC on Linux TCP SOCK_STREAM socket

Currently, lighttpd supports only TCP SOCK_STREAM.  If UDP SOCK_DGRAM
were to be supported in the future, then socket type will need to be
stored so that MSG_TRUNC is used appropriately for the desired effect.

To find out socket type on arbitrary socket fd:
  getsockopt(..., SOL_SOCKET, SO_TYPE, ...)
but better to store it with each listening socket.

Glenn Strauss 9030cfaecf [core] SIGCHLD handle_waitpid hook for modules
centralize most waitpid() handling in core server, with hooks for
modules to be informed of pid and status when a process exits.

This enables faster discovery (and restart) of exited processes,
and also allows for lighttpd to manage backend processes in the
parent (master) process when server.max-worker > 0.
