+  headers: remove checks for and defines of variable sizes
+  
+  ... they're not really used and by avoiding them in the ares_build.h
+  output we make the public header less dependent on data sizes.
+
+David Drysdale (24 Sep 2016)
+- api: add ARES_OPT_NOROTATE optmask value
+  
+  Fix up a couple of problems with configuring whether c-ares rotates
+  between different name servers between requests.
+  
+  Firstly, ares_save_options() returns (in *optmask) the value of
+  (channel->optmask & ARES_OPT_ROTATE), which doesn't necessarily
+  indicate whether the channel is or is not actually doing rotation.
+  This can be confusing/incorrect if:
+   - the channel was originally configured without ARES_OPT_ROTATE
+     (so it appears that the channel is not rotating)
+   - the /etc/resolv.conf file includes the 'rotate' option
+     (so the channel is actually performing rotation).
+  
+  Secondly, it is not possible to reliably configure a channel
+  to not-rotate; leaving off ARES_OPT_ROTATE is not enough, since
+  a 'rotate' option in /etc/resolv.conf will turn it on again.
+  
+  Therefore:
+   - add an ARES_OPT_NOROTATE optmask value to allow explicit
+     configuration of no-rotate behaviour
+   - in ares_save_options(), report the value of channel->rotate
+     as exactly one of (optmask & ARES_OPT_ROTATE) or
+     (optmask & ARES_OPT_NOROTATE).
+  
+  In terms of back-compatibility:
+   - existing apps that set ARES_OPT_ROTATE will continue to rotate,
+     and to have ARES_OPT_ROTATE reported back from ares_save_options()
+   - existing apps that don't set ARES_OPT_ROTATE will continue to
+     use local config/defaults to decide whether to rotate, and will
+     now get ARES_OPT_ROTATE or ARES_OPT_NOROTATE reported back from
+     ares_save_options() rather than 0.
+
+- ares_init_options: only propagate init failures from options
+  
+  Commit 46bb820be3a8 ("ares_init_options: don't lose init failure")
+  changed init behaviour so that earlier errors in initialization
+  weren't lost.  In particular, if the user passes in specific
+  options but they are not applied (e.g. because of an allocation
+  failure), that failure needs to be reported back to the user; this
+  also applies when duplicating a channel with ares_dup().
+  
+  However, other initialization failures can be ignored and
+  overridden -- in particular, if init_by_resolv_conf() or
+  init_by_environment() fail, then falling back to default values
+  is OK.
+  
+  So only preserve failures from the init_by_options() stage, not
+  from all initialization stages.
+  
+  Fixes issue 60.
+
+- test: Force reinstall of libtool on OSX
+  
+  Travis build environment appears to have changed.
+
+- test: Add valgrind build variant
+
+- test: Add null pointer to gtest args
+  
+  GoogleTest assumes that there is a null pointer in argv[argc],
+  so make it look like that. Without this change, tests run with
+  command-line arguments get memory errors under valgrind/ASAN.
+
+Daniel Stenberg (21 Aug 2016)
+- AUTHOR: maybe gitgub isn't really an author =)
+
+- AUTHORS: added contributors from the git log
+
+- LICENSE.md: add a stand-alone license file
+  
+  Just the MIT license used in the top the source files moved out to a
+  stand-alone file for easier reference and discovery.
+
+- README: added "CII best practices" badge
+
+- SECURITY.md: suggested "security process" for the project
+
+David Drysdale (17 Aug 2016)
+- test: Add Clang static analysis build to Travis
+  
+  Run scan-build over the library source code, but skip the
+  tests.  Needs a later Clang install in Travis
+
+- test: more info on how to run fuzz testing
+
+- test: make fuzzer driver code C not C++
+
+- test: fuzzer mode for AFL's persistent mode
+  
+  When fuzzing with AFL, if the LLVM-based instrumentation is
+  used (via the afl-clang-fast wrapper), then it is possible to
+  have a single execution of the fuzzer program iterate multiple
+  times over the fuzzing entrypoint (similar to libFuzzer's normal
+  mode of execution) with different data.  This is much (e.g. 10x)
+  faster.
+  
+  Add code to support this, by checking whether __AFL_LOOP is
+  defined at compile-time.
+  
+  Also, shift the code to effectively be C rather than C++.
+
+- test: simplify deps for fuzzer entrypoint
+  
+  No need to depend on the rest of the test code (ares-test.h) for
+  the fuzzer entrypoint; this makes the entrypoint slightly simpler
+  to build with LLVM's libFuzzer.
+  
+  Also shift the code to effectively be C rather than C++
+
+- test: disable MinGW tests
+  
+  The test binary built in the MinGW build is failing for some
+  reason.  It works for me when I build locally, so I'm guessing
+  it's down to some sort of AppVeyor environment issue.
+  
+  Disable for now.
+
+Daniel Stenberg (16 Aug 2016)
+- read_tcp_data: remove superfluous NULL check
+  
+  CID 56884 by Coverity. The pointer is already derefenced before this
+  point so it can't be NULL here anyway.

+- test: Run fuzzcheck.sh in Travis build
+
+- test: add fuzzing check script to tests
+  
+  Add a test script that runs the fuzzing command over the
+  corpus of DNS packets.  This doesn't actually do any fuzzing
+  (it just runs them as inputs without generating any variations)
+  but it does ensure that the fuzzing entrypoint is still working.
+
+- test: allow multiple files in aresfuzz command line
+  
+  If no arguments are specified, use stdin as input.
+  Otherwise treat each argument as a filename and feed
+  its contents to the fuzz entrypoint.
+
+- test: Add corpus of DNS packets
+  
+  For fuzz testing it is useful to start from a corpus of valid
+  packets, so fill out the test/fuzzinput/ directory with a bunch
+  of inputs.
+  
+  These packets were generated by temporarily modifying the c-ares
+  process_answer() function to save off any incoming response messages.
+
+- test: Add utility to show DNS packet from file
+

+  Fix nsort initialization

+  http://c-ares.haxx.se/mail/c-ares-archive-2014-07/0014.shtml
+
+- test: Check setting nsort=0 option is respected
+
+- test: Update fuzzing function prototype
+  
+  libFuzzer changed expected return type from void to int
+  in LLVM 3.8.
+
+- Explicitly clear struct servent before use
+  
+  On a build where MSAN has been manually set up (which involves
+  using an MSAN-instrumented version of the standard C++ library, see
+  https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo)
+  there's a warning about use of uninitialized memory here.  It
+  might be a false positive, but the fix is trivial so include it.
+
+- test: for AF_UNSPEC, return CNAME only for AAAA, but valid A record
+  
+  Also shuffle expected responses rsp6/rsp4 into the order they will occur.
+
+- [Chris Araman brought this change]
+
+  msvc_ver.inc: support Visual Studio 2015 Update 1
+
+- build: commonize MSVC version detection
+  
+  Remove the need to copy/paste version number mapping between
+  Makefile.msvc and test/Makefile.msvc.
+
+- test: Use different name in live test
+
+- test: Only pass unused args to GoogleTest
+
+- ahost.c: add cast to fix C++ compile
+  
+  If ahost.c is force-compiled as C++ the missing cast from
+  (void *) to (char **) is problematic.
+
+- ares_library_cleanup: reset ares_realloc too
+  
+  Otherwise a subsequent use of the library might use a previous
+  incarnation's realloc() implementation.
+
+Daniel Stenberg (9 Mar 2016)
+- [Brad House brought this change]
+
+  configure: check if tests can get built before enabled
+  
+  The current approach for disabling tests is not a good solution because
+  it forces you to pass --disable-tests, rather than auto-detect if your
+  system can support the tests in the first place.  Many (most?) systems
+  do not have C++11.  This also causes issues when chain-building c-ares,
+  the hosting system needs to be updated to support passing this
+  additional flag if necessary, it doesn't seem reasonable to add this
+  requirement which breaks compatibility.
+  
+  This change auto-detects if the system can build the tests and
+  automatically disable them if it cannot.  If you pass --enable-tests to
+  configure and the system cannot build them either due to lack of system
+  support, or because cross-compilation is being used, it will throw an
+  appropriate error since the user indicated they really did want the
+  tests.

-
-- move reentrant.m4 to the m4 subdirectory to avoid infinite loop inclusion problem
-
-- add checks for strtok_r and getprotobyname_r
-
-- Another step towards detecting if _REENTRANT is already defined or actually
-  needed, and being able to define it if appropriate for further configure tests
-  as well as for the generated config file.
-  
-  Introduced reentrant.m4 intended for our reentrant related autotools/m4 macros.
-
-- reorder argument number detection for getservbyport_r to
-  actually verify if the test is properly working
-
-- Make sure that configure process tests are done with the same _REENTRANT
-  setting as the one actually used when finally building the library.
-
-- Change recvfrom's sixth argument data type to the 'historically standard' 'int'
-  data type for systems where this sixth argument is prototyped as a void pointer.
-  
-  Start of thread: http://curl.haxx.se/mail/lib-2008-07/0153.html
-
-- use prototypes to improve getservbyport_r detection
-
-- Adjust recvfrom's sixth arg data type definition for NetWare (LIBC)
-
-- Use the sreadfrom() wrapper to replace recvfrom() in our code.
-
-- when recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
-  now cause the definition of RECVFROM_TYPE_ARG2_IS_VOID, RECVFROM_TYPE_ARG5_IS_VOID
-  or RECVFROM_TYPE_ARG6_IS_VOID, as appropriate.
-
-- Adjust DEC/Compaq C compiler settings
-
-- Added "pointer to void" as another data type to check for the sixth argument of
-  function recvfrom as a result of the info additionally logged when running on a
-  Solaris system.
-  
-  The compiler error showed that the prototype being used on Solaris was the one
-  declared in line 427 of "/usr/include/sys/socket.h" as:
-  
-  function(int,
-           pointer to void,
-           unsigned int,
-           int,
-           pointer to struct sockaddr,
-           pointer to void) returning int
-
-- Adjust DEC/Compaq C compiler settings
-
-- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
-  to the data type pointed by its respective argument and not the pointer type.
-
-- Configure process now checks availability of recvfrom() socket function and
-  finds out its return type and the types of its arguments. Added definitions
-  for non-configure systems config files, and introduced macro sreadfrom which
-  will be used on udp sockets as a recvfrom() wrapper.
-
-- Initial DEC/Compaq C compiler detection and flags
-
-- Improved configure detection of number of arguments for getservbyport_r
-
-- Allow --enable-largefile and --disable-largefile configurations.
-  Configure process no longer needs nor checks size of curl_off_t.
-  Library will now be built with _REENTRANT symbol defined.
-
-- fix compiler warning
-
-- since Jun 30 2008 MAXHOSTNAMELEN define is no longer used
-
-- fix c-ares version reported in generated libcares.pc file when building
-  from CVS tree.
-
-- egrep and ar are also mandatory
-
-Daniel Stenberg (3 Jul 2008)
-- just to clarify that c-ares actually have some ipv6 support
-
-- ares_gethostbyname() fallback from AAA to A records with CNAME present
-
-- - Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
-    the target host has only A records, it automatically falls back to an
-    AF_INET lookup and gives you the A results.  However, if the target host has
-    a CNAME record, this behaviour is defeated since the original query does
-    return some data even though ares_parse_aaa_reply() doesn't consider it
-    relevant. Here's a small patch to make it behave the same with and without
-    the CNAME.

-Yang Tse (2 Jul 2008)
-- The configure process will now halt when sed or grep are unavailable
-
-- fallback to gettimeofday when monotonic clock is unavailable at run-time
-
-- IBM C/C++ compiler predefined macro check
-
-- set earlier in configure process IBM compilers optimization flags
-
-- make check message wording more precise
-
-Daniel Stenberg (30 Jun 2008)
-- - As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
-    not posix or anything and thus c-ares failed to build on hurd (and possibly
-    elsewhere). The define was also somewhat artificially used in the windows
-    port. Now, I instead rewrote the use of gethostbyname to enlarge the host
-    name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
-    define. I thus also removed the defien from the namser.h file where it was
-    once added for the windows build.
-  
-    I also fixed init_by_defaults() function to not leak memory in case if
-    error.
-
-Yang Tse (29 Jun 2008)
-- fix C style comment
-
-- John Lightsey filed bug report #1999181: "CLOCK_MONOTONIC always fails on
-  some systems" (http://curl.haxx.se/bug/view.cgi?id=1999181). The problem was
-  that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
-  macro when checking monotonic clock availability. This is now fixed and the
-  monotonic clock will not be used unless the feature test macro is defined
-  with a value greater than zero indicating always supported.
-
-- Modified configuration script to actually verify if the compiler is good
-  enough at detecting compilation errors or at least it has been properly
-  configured to do so. Configuration heavily depends on this capability, so
-  if this compiler sanity check fails the configuration process will now fail.

+.SH NAME
+ares_init_options \- Initialize a resolver channel
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+int ares_init_options(ares_channel *\fIchannelptr\fP,
+                      struct ares_options *\fIoptions\fP,
+                      int \fIoptmask\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_init_options(3)\fP function initializes a communications channel
+for name service lookups.  If it returns successfully,
+\fBares_init_options(3)\fP will set the variable pointed to by
+\fIchannelptr\fP to a handle used to identify the name service channel.  The
+caller should invoke \fIares_destroy(3)\fP on the handle when the channel is
+no longer needed.
+
+The \fIoptmask\fP parameter generally specifies which fields in the structure pointed to
+by \fIoptions\fP are set, as follows:
+.TP 18
+.B ARES_OPT_FLAGS
+.B int \fIflags\fP;
+.br
+Flags controlling the behavior of the resolver.  See below for a
+description of possible flag values.
+.TP 18
+.B ARES_OPT_TIMEOUT
+.B int \fItimeout\fP;
+.br
+The number of seconds each name server is given to respond to a query on the
+first try.  (After the first try, the timeout algorithm becomes more
+complicated, but scales linearly with the value of \fItimeout\fP.)  The
+default is five seconds. This option is being deprecated by
+\fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2.
+.TP 18
+.B ARES_OPT_TIMEOUTMS
+.B int \fItimeout\fP;
+.br
+The number of milliseconds each name server is given to respond to a query on
+the first try.  (After the first try, the timeout algorithm becomes more
+complicated, but scales linearly with the value of \fItimeout\fP.)  The
+default is five seconds. Note that this option is specified with the same
+struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits
+that tell c-ares how to interpret the number. This option was added in c-ares
+1.5.2.
+.TP 18
+.B ARES_OPT_TRIES
+.B int \fItries\fP;
+.br
+The number of tries the resolver will try contacting each name server
+before giving up.  The default is four tries.
+.TP 18
+.B ARES_OPT_NDOTS
+.B int \fIndots\fP;
+.br
+The number of dots which must be present in a domain name for it to be
+queried for "as is" prior to querying for it with the default domain
+extensions appended.  The default value is 1 unless set otherwise by
+resolv.conf or the RES_OPTIONS environment variable.
+.TP 18
+.B ARES_OPT_UDP_PORT
+.B unsigned short \fIudp_port\fP;
+.br
+The port to use for queries over UDP, in network byte order.
+The default value is 53 (in network byte order), the standard name
+service port.
+.TP 18
+.B ARES_OPT_TCP_PORT
+.B unsigned short \fItcp_port\fP;
+.br
+The port to use for queries over TCP, in network byte order.
+The default value is 53 (in network byte order), the standard name
+service port.
+.TP 18
+.B ARES_OPT_SERVERS
+.B struct in_addr *\fIservers\fP;
+.br
+.B int \fInservers\fP;
+.br
+The list of IPv4 servers to contact, instead of the servers specified in
+resolv.conf or the local named. In order to allow specification of either
+IPv4 or IPv6 name servers, the
+.BR ares_set_servers(3)
+function must be used instead.
+.TP 18
+.B ARES_OPT_DOMAINS
+.B char **\fIdomains\fP;
+.br
+.B int \fIndomains\fP;
+.br
+The domains to search, instead of the domains specified in resolv.conf
+or the domain derived from the kernel hostname variable.
+.TP 18
+.B ARES_OPT_LOOKUPS
+.B char *\fIlookups\fP;
+.br
+The lookups to perform for host queries.
+.I lookups
+should be set to a string of the characters "b" or "f", where "b"
+indicates a DNS lookup and "f" indicates a lookup in the hosts file.
+.TP 18
+.B ARES_OPT_SOCK_STATE_CB
+.B void (*\fIsock_state_cb\fP)(void *data, int s, int read, int write);
+.br
+.B void *\fIsock_state_cb_data\fP;
+.br
+A callback function to be invoked when a socket changes state.
+.I s
+will be passed the socket whose state has changed;
+.I read
+will be set to true if the socket should listen for read events, and
+.I write
+will be set to true if the socket should listen for write events.
+The value of
+.I sock_state_cb_data
+will be passed as the
+.I data
+argument.
+.TP 18
+.B ARES_OPT_SORTLIST
+.B struct apattern *\fIsortlist\fP;
+.br
+.B int \fInsort\fP;
+.br
+A list of IP address ranges that specifies the order of preference that
+results from \fIares_gethostbyname\fP should be returned in.  Note that
+this can only be used with a sortlist retrieved via
+\fBares_save_options(3)\fP (because
+.B struct apattern
+is opaque); to set a fresh sort list, use \fBares_set_sortlist(3)\fP.
+.TP 18
+.B ARES_OPT_SOCK_SNDBUF
+.B int \fIsocket_send_buffer_size\fP;
+.br
+The send buffer size to set for the socket.
+.TP 18
+.B ARES_OPT_SOCK_RCVBUF
+.B int \fIsocket_receive_buffer_size\fP;
+.br
+The receive buffer size to set for the socket.
+.TP 18
+.B ARES_OPT_EDNSPSZ
+.B int \fIednspsz\fP;
+.br
+The message size to be advertized in EDNS; only takes effect if the
+.B ARES_FLAG_EDNS
+flag is set.
+.br
+.PP
+The \fIoptmask\fP parameter also includes options without a corresponding
+field in the
+.B ares_options
+structure, as follows:
+.TP 23
+.B ARES_OPT_ROTATE
+Perform round-robin selection of the nameservers configured for the channel
+for each resolution.
+.TP 23
+.B ARES_OPT_NOROTATE
+Do not perform round-robin nameserver selection; always use the list of
+nameservers in the same order.
+.PP
+The
+.I flags
+field should be the bitwise or of some subset of the following values:
+.TP 23
+.B ARES_FLAG_USEVC
+Always use TCP queries (the "virtual circuit") instead of UDP
+queries.  Normally, TCP is only used if a UDP query yields a truncated
+result.
+.TP 23
+.B ARES_FLAG_PRIMARY
+Only query the first server in the list of servers to query.
+.TP 23
+.B ARES_FLAG_IGNTC
+If a truncated response to a UDP query is received, do not fall back
+to TCP; simply continue on with the truncated response.
+.TP 23
+.B ARES_FLAG_NORECURSE
+Do not set the "recursion desired" bit on outgoing queries, so that the name
+server being contacted will not try to fetch the answer from other servers if
+it doesn't know the answer locally. Be aware that ares will not do the
+recursion for you.  Recursion must be handled by the application calling ares
+if \fIARES_FLAG_NORECURSE\fP is set.
+.TP 23
+.B ARES_FLAG_STAYOPEN
+Do not close communications sockets when the number of active queries
+drops to zero.
+.TP 23
+.B ARES_FLAG_NOSEARCH
+Do not use the default search domains; only query hostnames as-is or
+as aliases.
+.TP 23
+.B ARES_FLAG_NOALIASES
+Do not honor the HOSTALIASES environment variable, which normally
+specifies a file of hostname translations.
+.TP 23
+.B ARES_FLAG_NOCHECKRESP
+Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED
+response code or responses whose questions don't match the questions
+in the request.  Primarily useful for writing clients which might be
+used to test or debug name servers.
+.TP 23
+.B ARES_FLAG_EDNS
+Include an EDNS pseudo-resource record (RFC 2671) in generated requests.
+.SH RETURN VALUES
+\fBares_init_options(3)\fP can return any of the following values:
+.TP 14
+.B ARES_SUCCESS
+Initialization succeeded.
+.TP 14
+.B ARES_EFILE
+A configuration file could not be read.
+.TP 14
+.B ARES_ENOMEM
+The process's available memory was exhausted.
+.TP 14
+.B ARES_ENOTINITIALIZED
+c-ares library initialization not yet performed.
+.SH NOTES
+When initializing from
+.B /etc/resolv.conf,
+\fBares_init_options(3)\fP reads the \fIdomain\fP and \fIsearch\fP directives
+to allow lookups of short names relative to the domains specified. The
+\fIdomain\fP and \fIsearch\fP directives override one another. If more that
+one instance of either \fIdomain\fP or \fIsearch\fP directives is specified,
+the last occurrence wins. For more information, please see the
+.BR resolv.conf (5)
+manual page.
