ChangeLog

Mon May  2 06:08:26 CEST 2016
	Adding logic to help address FE performance issue as
	discussed on the mailinglist with subject
        "single-threaded daemon, multiple pending requests, responses batched".
	The new logic is only enabled when MHD_USE_EPOLL_TURBO is set.
	Note that some additional refactoring was also done to clean up
	the code and avoid code duplication, which may have actually fixed
	an unrelated issue with HTTPS and a POLL-style event loop. -CG

	Fixing transient resource leak affecting long-lived
	connections with many keep-alives and HTTP request
	pipelining under certain circumstances (which reduced
	the receive window).
	Fixed assertion failure triggered by a race in
	thread-per-connection mode on shutdown in rare
	circumstances. -CG

Mon Oct  5 11:53:52 CEST 2015

	Markus Doppelbauer for reporting. -CG

Fri Jun 26 23:17:20 CEST 2015
	Fix (automatic) handling of HEAD requests with
	MHD_create_response_from_callback() and HTTP/1.1

	Add new functions MHD_create_response_from_fd64() and
	MHD_create_response_from_fd_at_offset64(). -EG

Sat Apr  4 17:48:13 CEST 2015
	Fix issue in thread-pool mode where a MHD_stop_daemon()
	might not reach threads that stopped listening because
	we hit the maximum number of concurrent connections and
	the option MHD_USE_PIPE_FOR_SHUTDOWN was also not used.
	Testcase added as well. -CG

Fri Apr  3 12:55:31 CEST 2015
	Update HTTPS testcases to avoid SSLv3, as SSLv3 is dead.

Fri Apr  3 12:25:28 CEST 2015
	Do not enforce FD_SETSIZE-limit on worker control
	pipe when using MHD_USE_EPOLL_LINUX_ONLY (#3751). -MH/CG

Tue Mar 31 10:28:26 CEST 2015
	Adding MHD_OPTION_NOTIFY_CONNECTION,
	MHD_CONNECTION_NOTIFY_STARTED,
	MHD_CONNECTION_NOTIFY_CLOSED and
	MHD_CONNECTION_INFO_SOCKET_CONTEXT to allow
	applications to trigger operations when TCP
	connections start or end, instead of just

	Fixing bug that prevented MHD_OPTION_HTTPS_MEM_DHPARAMS
	from working within a MHD_OPTION_ARRAY. -DD

Thu Jun 26 21:06:04 CEST 2014
	Fix failure to terminate 'instantly' in thread-per-connection
	mode if there is a client with open connections.
	Thanks to Kenneth Mastro for reporting. -CG

Sun Jun 22 12:22:08 CEST 2014
	Actually, avoid locking on response as responses must
	not be modified in a connection-specific way; instead
	modify the connection's data buffer to add missing
	responses headers.  If we are forced to add
	"Connection: close", suppress output of conflicting
	application-provided "Connection: Keep-Alive" header. -CG

Sun Jun 22 00:22:08 CEST 2014
	Lock on response if adding headers, needed if response
	object is shared across threads and connections. -CG

Thu Jun 19 17:32:32 CEST 2014
	Ensure that listen FD is bound to epoll FD even before
	MHD_run() is called if running with MHD_USE_EPOLL_LINUX_ONLY
	in combination with 'external select' mode.  Thanks to
	Marcos Pindado Sebastian for reporting. -CG

Sun Jun  8 15:10:44 CEST 2014
	Add 'MHD_set_response_options' as a way to set per-response

	behavior, in particular suppressing adding "Connection"
	headers. -CG

Mon Jun  2 00:03:28 CEST 2014
	Added back unescaping for URI path (#3413) but without
	unescaping '+' (#3371) to remain compatible with
	MHD 0.9.34 and before.  Note that applications providing
	a custom MHD_OPTION_UNESCAPE_CALLBACK are no longer expected
	to replace '+' with ' ', as that is now done separately for
	the locations where this transformation is appropriate.
	Releasing 0.9.37. -CG

Wed May 28 15:30:56 CEST 2014
	Properly applying patch that was supposed to be
	committed on "May  2 20:22:45 CEST 2014" to address
	infinite loop (DoS) when HTTP connection is reset (#3392). -GM

Sun May 25 20:18:27 CEST 2014

	under certain circumstances. -CG

Tue May 13 18:24:37 CEST 2014
	Fix accidental transmission of footer termination '\r\n'
	for responses with zero byte payload and non-chunked
	encoding (#3397).  Thanks to amatus for reporting. -CG

	logic if edge trigger event is lost; also simplify logic to
	maintain simpler invariants on the epoll state. -CG
	Use OpenSSL cipher list "HIGH" in libmicrospdy (#3391). -CG
	Releasing 0.9.35. -CG

Thu Apr 10 09:39:38 CEST 2014
	Removed unescaping for URI path (#3371) as '+' should not
	be converted to space in accordance with
	http://www.w3.org/TR/html401/appendix/notes.html#ampersands-in-uris
	and http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.1
	Note that we now also no longer convert '#38;' to '&'; if needed,
	the application needs to apply unescaping to the path of the URI
	itself (before, MHD unescaped '#38;' but not '&', so this
	inconsistency was now resolved by simply not unescaping anything
	before the first '&'). -CG

Tue Apr 08 15:35:44 CET 2014
	Added support for W32 native threads.
	Added --with-threads=LIB configure parameter. -EG

Mon Apr  7 13:25:30 CEST 2014

	Added more FD_SETSIZE checks.
	Implemented FD_SETSIZE checks for W32. -EG

	Cleanup and refactoring of configure.ac.
	m4 macros updated.
	Custom configure macros replaced with autoconf archive macros.
	SPDY disabled by default on W32.
	Changed configure flag from '--disable-pipe' to
	'--enable-socketpair'.
	Added configure flags '--disable-doc' and '--disable-examples'.
	Narrowed down extrenal lib specific compiler and linker flags
	usage. -EG

Wed Feb 26 17:42:34 CET 2014
	Refactoring of configure.ac: custom macros replaced with macros
	from Autoconf Archive.

	Added support for TCP FASTOPEN. -SHT
	Releasing 0.9.34. -CG

Thu Feb 20 14:17:05 CET 2014
	W32: Added creation of libmicrohttpd.lib, libmicrohttpd.def,
	libmicrohttpd.exp and libmicrohttpd-static.lib for easy use
	compiled MHD with MSVC.
	W32: Use MS lib.exe tool if available for creating MSVC staff.
	W32: Added .dll information resource. -EG

Tue Feb 18 19:46:45 CET 2014
	Removed dependency on plibc for simpler compilation for W32.
	Added configure option "--disable-pipes" to use socketpairs
	instead of pipes for signalling to child threads. Pipes are
	always disabled on W32.
	Some code refactoring. -EG

Sat Feb  8 15:08:35 CET 2014
	Corrected some uses of 'int' vs. 'size_t'. -EG/CG

Wed Jan 22 09:44:33 CET 2014
	MHD_USE_DUAL_STACK in libmicrohttpd currently just *inhibits
	setting* the IPV6_V6ONLY socket option, but per Microsoft's
	documentation the default on Windows is that this is enabled, thus
	MHD_USE_DUAL_STACK will not work (since it leaves the
	default). libmicrohttpd should probably just unconditionally set
	IPV6_V6ONLY to the desired value when the option is available. -LJ

Wed Jan  1 21:38:18 CET 2014
	Allow Keep-Alive with HTTP 1.0 (if explicitly requested),
	and automatically set "Connection: Keep-Alive" in response
	in this case as well. -CG

	Signaling n times for shutdown works, but for resume we need to
	wake up the correct daemon. Even if we signal n times in that
	case also, there's no guarantee that some daemon can't run
	through its select loop more than once before the daemon we want
	to wake up gets a chance to read.  Thus we need a signal pipe
	per thread in the thread pool IF MHD_suspend_connection is used.
	This introduces a new flag MHD_USE_SUSPEND_RESUME to add those
	additional pipes and only allow MHD_suspend_connection to be
	used in conjunction with this flag.

	Also, as MHD_resume_connection() will be called on a non-daemon
	thread, but none of the queue insert/delete calls are thread safe,
	we need to be concerned about (a) corrupting the queue, and (b)
	having to add mutex protection around every access to the queues,
	including loops through timer queues, etc. This wasn't a problem
	before adding resume; even suspend should be safe since it happens
	in a callback from the daemon.

	I think it's easier to (a) have MHD_suspend_connection() move the
	connection to a suspended queue, (b) have MHD_resume_connection()
	mark the connection as resuming, and then (c) do all the actual
	queue manipulations in MHD_select (poll, epoll, etc.) to move the
	resumed connections back to their normal queues, in response to
	the wake up. The changes are simpler & cleaner. There is a cost to
	the basic select loop that is avoided by making suspend/resume a
	startup option. The per-worker pipes can then also be enabled only
	with that option set. -MH

Fri Nov 29 20:17:03 CET 2013
	Eliminating theoretical stack overflow by limiting length

	If we shutdown connection for reading on POST due to error,
	really do not process further requests even if we already

	Added option 'MHD_USE_PIPE_FOR_SHUTDOWN' to cleanly support

	'MHD_quiesce_daemon' is not used, we do not want to
	require the use of a pipe; introducing the pipe after
	the threads have been started can also fail, so the

Sun Mar 31 20:03:48 CEST 2013
	Performance improvements, updated documentation.
	Make better use of available memory pool memory for
	reading (especially important for large POST uploads);
	improve post processor speed by internally adjusting the
	buffer size by 4 bytes to ensure "round" IO sizes given
	a "round" post processor buffer size argument.  Note
	that applications that previously added 4 bytes to the
	post processor buffer size might now perform worse.
	Using the new 'demo' example, POST upload speed
	increased from ~90 MB/s to ~120 MB/s for a large file
	(note that the improvement comes from better aligned
	disk IO; without disk IO, the speed was (and remains)
	at ~1500 MB/s on this system). -CG
