See http://github.com/bagder/c-ares + +* March 5, 2010 (Daniel Stenberg) +- Daniel Johnson provided fixes for building with the clang compiler. + +* March 5, 2010 (Yang Tse) +- Added IPv6 name servers support. Implementation has been based on code, + comments and feedback provided November and December of 2008 by Daniel + Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric + Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On + March I reviewed all that, selected the best of each, and adjusted or + extended parts of it to make the best fit. + + The external and visible result of all this is that two new functions are + added to the external API, ares_get_servers() and ares_set_servers(), which + becomes now the preferred way of getting and setting name servers for any + ares channel as these support both IPv4 and IPv6 name servers. + + In order to not break ABI compatibility, ares_init_options() with option + mask ARES_OPT_SERVERS and ares_save_options() may still be used in code + which is intended to run on IPv4-only stacks. But remember that these + functions do not support IPv6 name servers. This implies that if the user + is capable of defining or providing an IPv6 name server, and the app is + using ares_init_options() or ares_save_options() at some point to handle + the name servers, the app will likely lose IPv6 name servers. + +* January 28, 2010 (Daniel Stenberg) +- Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't + check for broken connections like ares_process() did.

This + file is only for CVS tree checkout builds. + +* May 26 2009 (Yang Tse) +- Added --enable-curldebug configure option to enable and disable building + with the low-level curl debug memory tracking 'feature' to allow decoupled + setting from --enable-debug, allowing again to build c-ares independently + out of the CVS tree. + + For the c-ares library option --enable-debug enables debug build features + which are _not_ related with memory tracking. For the c-ares library when + --enable-debug is given it does not enable the memory tracking feature. If + you wish to enable the curl debug memory tracking you must use configure + option --enable-curldebug explicitily to do so. + + Internally, definition of preprocessor symbol DEBUGBUILD restricts code + which is only compiled for debug enabled builds. And symbol CURLDEBUG is + used to differentiate code which is _only_ used for memory tracking. + + Make ares_init(), ares_dup() and ares_init_options() fail returning + ARES_ENOTINITIALIZED if library initialization has not been performed + calling ares_library_init(). + +* May 20 2009 (Yang Tse) +- Added ares_library_init() and ares_library_cleanup() man pages. + +* May 19 2009 (Yang Tse) +- Introduced ares_library_init() and ares_library_cleanup() functions. + + This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets + using c-ares 1.7.0 can still survive without calling these functions. Read all + the details on ares_library_init(3) and ares_library_cleanup(3) man pages that + are included. + + curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems. + + In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is + required that curl/libcurl is 7.19.5 or newer. In other words, it is not + possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less + than 7.19.5 + +* May 11 2009 (Daniel Stenberg) +- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to + only expose functions starting with ares_. + +* May 7 2009 (Yang Tse) +- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition + attempt in generated config.h + +* May 2 2009 (Yang Tse) +- Use a build-time configured ares_socklen_t data type instead of socklen_t. + +* April 21 2009 (Yang Tse) +- Moved potential inclusion of system's malloc.h and memory.h header files to + setup_once.h. Inclusion of each header file is based on the definition of + NEED_MALLOC_H and NEED_MEMORY_H respectively. + +* March 11 2009 (Yang Tse) +- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long. + +* February 20 2009 (Yang Tse) +- Do not halt compilation when using VS2008 to build a Windows 2000 target. + +* February 3 2009 (Phil Blundell) +- If the server returns garbage or nothing at all in response to an AAAA query, + go on and ask for A records anyway. + +* January 31 2009 (Daniel Stenberg) +- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving + either AF_INET6 or AF_INET. It works by accepting any of the looksups in the + hosts file, and it resolves the AAAA field with a fallback to A. + +* January 14 2009 (Daniel Stenberg) +- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it + now declares the private struct ares_in6_addr for all systems instead of + relying on one possibly not present in the system. + +* January 13 2009 (Phil Blundell) +- ares__send_query() now varies the retry timeout pseudo-randomly to avoid + packet storms when several queries were started at the same time. + +* January 11 2009 (Daniel Stenberg) +- Phil Blundell added the internal function ares__expand_name_for_response() + that is now used by the ares_parse_*_reply() functions instead of the + ares_expand_name() simply to easier return ARES_EBADRESP for the cases where + the name expansion fails as in responses that really isn't expected. + +Version 1.6.0 (Dec 9, 2008) + +* December 9 2008 (Gisle Vanem) + + Fixes for Win32 targets using the Watt-32 tcp/ip stack. + +* Dec 4 2008 (Daniel Stenberg) + + Gregor Jasny provided the patch that introduces ares_set_socket_callback(), + and I edited it to also get duped by ares_dup(). + +* Dec 3 2008 (Daniel Stenberg) + + API changes: + + I made sure the public ares_config struct looks like before and yet it + supports the ROTATE option thanks to c-ares now storing the "optmask" + internally. Thus we should be ABI compatible with the past release(s) + now. My efforts mentioned below should not break backwards ABI compliance. + + Here's how I suggest we proceed with the API: + + ares_init() will be primary "channel creator" function. + + ares_init_options() will continue to work exactly like now and before. For + starters, it will be the (only) way to set the existing options. + + ares_save_options() will continue to work like today, but will ONLY save + options that you can set today (including ARES_OPT_ROTATE actually) but new + options that we add may not be saved with this. + + Instead we introduce: + + ares_dup() that instead can make a new channel and clone the config used + from an existing channel. It will then clone all config options, including + future new things we add. + + ares_set_*() style functions that set (new) config options. As a start we + simply add these for new functionality, but over time we can also introduce + them for existing "struct ares_options" so that we can eventually deprecate + the two ares_*_options() functions. + + ares_get_*() style functions for extracting info from a channel handle that + should be used instead of ares_save_options(). + +* Nov 26 2008 (Yang Tse) +- Brad Spencer provided changes to allow buildconf to work on OS X. + +- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a + buffer to shrink instead of expand if a reply contained 8 or more records. + +* Nov 25 2008 (Yang Tse) +- In preparation for the upcomming IPv6 nameservers patch, the internal + ares_addr union is now changed into an internal struct which also holds + the address family. + +* Nov 19 2008 (Daniel Stenberg) +- Brad Spencer brought the new function ares_gethostbyname_file() which simply + resolves a host name from the given file, using the regular hosts syntax. + +* Nov 1 2008 (Daniel Stenberg) +- Carlo Contavalli added support for the glibc "rotate" option, as documented + in man resolv.conf: + + causes round robin selection of nameservers from among those listed. This + has the effect of spreading the query load among all listed servers, rather + than having all clients try the first listed server first every time. + + You can enable it with ARES_OPT_ROTATE + +* Oct 21 2008 (Yang Tse) + Charles Hardin added handling of EINPROGRESS for UDP connects. + +* Oct 18 2008 (Daniel Stenberg) + Charles Hardin made adig support a regular numerical dotted IP address for the + -s option as well. + +* Oct 7 2008 (Yang Tse) +- Added --enable-optimize configure option to enable and disable compiler + optimizations to allow decoupled setting from --enable-debug. + +* Oct 2 2008 (Yang Tse) +- Added --enable-warnings configure option to enable and disable strict + compiler warnings to allow decoupled setting from --enable-debug. + +* Sep 17 2008 (Yang Tse) +- Code reorganization to allow internal/private use of "nameser.h" to any + system that lacks arpa/nameser.h or arpa/nameser_compat.h header files. + +* Sep 16 2008 (Yang Tse) +- Code reorganization to allow internal/private use of ares_writev to any + system that lacks the writev function. + +* Sep 15 2008 (Yang Tse) +- Code reorganization to allow internal/private use of ares_strcasecmp to any + system that lacks the strcasecmp function. + +- Improve configure detection of some string functions. + +* Sep 11 2008 (Yang Tse) +- Code reorganization to allow internal/private use of ares_strdup to any + system that lacks the strdup function. + +Version 1.5.3 (Aug 29, 2008) + +* Aug 25 2008 (Yang Tse) +- Improvement by Brad House: + + This patch addresses an issue in which a response could be sent back to the + source port of a client from a different address than the request was made to. + This is one form of a DNS cache poisoning attack. + + The patch simply uses recvfrom() rather than recv() and validates that the + address returned from recvfrom() matches the address of the server we have + connected to. Only necessary on UDP sockets as they are connection-less, TCP + is unaffected. + +- Fix by George Neill: + Fixed compilation of acountry sample application failure on some systems. + +* Aug 4 2008 (Daniel Stenberg) +- Fix by Tofu Linden: + + The symptom: + * Users (usually, but not always) on 2-Wire routers and the Comcast service + and a wired connection to their router would find that the second and + subsequent DNS lookups from fresh processes using c-ares to resolve the same + address would cause the process to never see a reply (it keeps polling for + around 1m15s before giving up). + + The repro: + * On such a machine (and yeah, it took us a lot of QA to find the systems + that reproduce such a specific problem!), do 'ahost www.secondlife.com', + then do it again. The first process's lookup will work, subsequent lookups + will time-out and fail. + + The cause: + * init_id_key() was calling randomize_key() *before* it initialized + key->state, meaning that the randomness generated by randomize_key() is + immediately overwritten with deterministic values. (/dev/urandom was also + being read incorrectly in the c-ares version we were using, but this was + fixed in a later version.) + * This makes the stream of generated query-IDs from any new c-ares process + be an identical and predictable sequence of IDs. + * This makes the 2-Wire's default built-in DNS server detect these queries + as probable-duplicates and (erroneously) not respond at all. + + +* Aug 4 2008 (Yang Tse) +- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use. + Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62 + version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols + no matter if the system is AIX or not. To keep the traditional behaviour, + and an uniform one across autoconf versions AC_AIX is replaced with our + own internal macro CARES_CHECK_AIX_ALL_SOURCE. + +* Aug 1 2008 (Yang Tse) +- Configure process now checks if the preprocessor _REENTRANT symbol is already + defined. If it isn't currently defined a set of checks are performed to test + if its definition is required to make visible to the compiler a set of *_r + functions. Finally, if _REENTRANT is already defined or needed it takes care + of making adjustments necessary to ensure that it is defined equally for the + configure process tests and generated config file. + +* Jul 20 2008 (Yang Tse) +- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will + now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID, + RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID. + +* Jul 17 2008 (Yang Tse) +- 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. + +* Jul 16 2008 (Yang Tse) +- Improved configure detection of number of arguments for getservbyport_r. + Detection is now based on compilation checks instead of linker ones. + +- 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 in the future. + +* Jul 15 2008 (Yang Tse) +- Introduce definition of _REENTRANT symbol in setup.h to improve library + usability. Previously the configure process only used the AC_SYS_LARGEFILE + macro for debug builds, now it is also used for non-debug ones enabling the + use of configure options --enable-largefile and --disable-largefile which + might be needed for library compatibility. Remove checking the size of + curl_off_t, it is no longer needed. + +* Jul 3 2008 (Daniel Stenberg) +- 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. + +* Jul 2 2008 (Yang Tse) +- Fallback to gettimeofday when monotonic clock is unavailable at run-time. + +* Jun 30 2008 (Daniel Stenberg) + +- 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. + +* Jun 9 2008 (Yang Tse) + +- Make libcares.pc generated file for pkg-config include information relative + to the libraries needed for the static linking of c-ares. + +* May 30 2008 (Yang Tse) + +- Brad House fixed a missing header file inclusion in adig sample program. + +Version 1.5.2 (May 29, 2008) + +* May 13 2008 (Daniel Stenberg) + +- Introducing millisecond resolution support for the timeout option. See + ares_init_options()'s ARES_OPT_TIMEOUTMS. + +* May 9 2008 (Yang Tse) + +- Use monotonic time source if available, for private function ares__tvnow() + +* May 7 2008 (Daniel Stenberg) + +- Sebastian made c-ares able to return all PTR-records when doing reverse + lookups. It is not common practice to have multiple PTR-Records for a single + IP, but its perfectly legal and some sites have those. + +- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to + autoconf 2.57 usage (which is the version you have specified as the minimum + version). It's a minor change but it does clean up some warnings with newer + autoconf (specifically 2.62). + +* May 5 2008 (Yang Tse) + +- Improved parsing of resolver configuration files. + +* April 4 2008 (Daniel Stenberg) + +- Eino Tuominen improved the code when a file is used to seed the randomizer. + +- Alexey Simak made adig support NAPTR records + +- Alexey Simak fixed the VC dsp file by adding the missing source file + ares_expand_string.c + +* December 11 2007 (Gisle Vanem) + +- Added another sample application; acountry.c which converts an + IPv4-address(es) and/or host-name(s) to country-name and country-code. + This uses the service of the DNSBL at countries.nerd.dk. + +* December 3 2007 (Daniel Stenberg) + +- Brad Spencer fixed the configure script to assume that there's no + /dev/urandom when built cross-compiled as then the script cannot check for + it. + +- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat + +Version 1.5.1 (Nov 21, 2007) + +* November 21 2007 (Daniel Stenberg) + +- Robin Cornelius pointed out that ares_llist.h was missing in the release + archive for 1.5.0 + +Version 1.5.0 (Nov 21, 2007) + +* October 2 2007 (Daniel Stenberg) + +- ares_strerror() segfaulted if the input error number was out of the currently + supported range. + +- Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in + internal function init_id_key() under low memory conditions. + +* September 28 2007 (Daniel Stenberg) + +- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI + and API changes in the progress callback (and possibly more coming up from + Steinar) + +* September 28 2007 (Steinar H. Gunderson) + +- Don't skip a server if it's the only one. (Bugfix from the Google tree.) + +- Made the query callbacks receive the number of timeouts that happened during + the execution of a query, and updated documentation accordingly. (Patch from + the Google tree.) + +- Support a few more socket options: ARES_OPT_SOCK_SNDBUF and + ARES_OPT_SOCK_RCVBUF + +- Always register for TCP events even if there are no outstanding queries, as + the other side could always close the connection, which is a valid event + which should be responded to. + +* September 22 2007 (Daniel Stenberg) + +- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in + several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that + if it fails and the socket is closed the following code doesn't try to use + the file descriptor. + +- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when + TCP is used since there are several edge cases where it still makes sense. + +- Brad House provided a fix for ares_save_options(): + + Apparently I overlooked something with the ares_save_options() where it + would try to do a malloc(0) when no options of that type needed to be saved. + On most platforms, this was fine because malloc(0) doesn't actually return + NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM. + +* July 14 2007 (Daniel Stenberg) + +- Vlad Dinulescu fixed two outstanding valgrind reports: + + 1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short + int variable) with qid, which is declared as an int variable. Moreover, + DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID + sets only the first two bytes of qid. I think that qid should be declared as + "unsigned short" in this function. + + 2. The same problem occurs in ares_process.c, process_answer() . query->qid + (an unsigned short integer variable) is compared with id, which is an + integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets + only the first two bytes of id. I think that the id variable should be + declared as "unsigned short" in this function. + + Even after declaring these variables as "unsigned short", the valgrind + errors are still there. Which brings us to the third problem. + + 3. The third problem is that Valgrind assumes that query->qid is not + initialised correctly. And it does that because query->qid is set from + DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And + qbuf has uninitialised bytes because of channel->next_id . And next_id is + set by ares_init.c:ares__generate_new_id() . I found that putting short r=0 + in this function (instead of short r) makes all Valgrind warnings go away. + I have studied ares__rc4() too, and this is the offending line: + + buffer_ptr[counter] ^= state[xorIndex]; (ares_query.c:62) + + This is what triggers Valgrind.. buffer_ptr is unitialised in this function, + and by applying ^= on it, it remains unitialised. + +Version 1.4.0 (June 8, 2007) + +* June 4 2007 (Daniel Stenberg) + +- James Bursa reported a major memory problem when resolving multi-IP names + and I found and fixed the problem. It was added by Ashish Sharma's patch + two days ago. + + When I then tried to verify multiple entries in /etc/hosts after my fix, I + got another segfault and decided this code was not ripe for inclusion and I + reverted the patch. + +* June 2 2007 + +- Brad Spencer found and fixed three flaws in the code, found with the new + gcc 4.2.0 warning: -Waddress + +- Brad House fixed VS2005 compiler warnings due to time_t being 64bit. + He also made recent Microsoft compilers use _strdup() instead of strdup(). + +- Brad House's man pages for ares_save_options() and ares_destroy_options() + were added. + +- Ashish Sharma provided a patch for supporting multiple entries in the + /etc/hosts file. Patch edited for coding style and functionality by me + (Daniel). + +* May 30 2007 + +- Shmulik Regev brought cryptographically secure transaction IDs: + + The c-ares library implementation uses a DNS "Transaction ID" field that is + seeded with a pseudo random number (based on gettimeofday) which is + incremented (++) between consecutive calls and is therefore rather + predictable. In general, predictability of DNS Transaction ID is a well + known security problem (e.g. + http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based + implementation vulnerable to DNS poisoning. Credit goes to Amit Klein + (Trusteer) for identifying this problem. + + The patch I wrote changes the implementation to use a more secure way of + generating unique IDs. It starts by obtaining a key with reasonable entropy + which is used with an RC4 stream to generate the cryptographically secure + transaction IDs. + + Note that the key generation code (in ares_init:randomize_key) has two + versions, the Windows specific one uses a cryptographically safe function + provided (but undocumented :) by the operating system (described at + http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx). The + default implementation is a bit naive and uses the standard 'rand' + function. Surely a better way to generate random keys exists for other + platforms. + + The patch can be tested by using the adig utility and using the '-s' option. + +- Brad House added ares_save_options() and ares_destroy_options() that can be + used to keep options for later re-usal when ares_init_options() is used. + + Problem: Calling ares_init() for each lookup can be unnecessarily resource + intensive. On windows, it must LoadLibrary() or search the registry + on each call to ares_init(). On unix, it must read and parse + multiple files to obtain the necessary configuration information. In + a single-threaded environment, it would make sense to only + ares_init() once, but in a heavily multi-threaded environment, it is + undesirable to ares_init() and ares_destroy() for each thread created + and track that. + + Solution: Create ares_save_options() and ares_destroy_options() functions to + retrieve and free options obtained from an initialized channel. The + options populated can be used to pass back into ares_init_options(), + it should populate all needed fields and not retrieve any information + from the system. Probably wise to destroy the cache every minute or + so to prevent the data from becoming stale. + +- Daniel S added ares_process_fd() to allow applications to ask for processing + on specific sockets and thus avoiding select() and associated + functions/macros. This function will be used by upcoming libcurl releases + for this very reason. It also made me export the ares_socket_t type in the + public ares.h header file, since ares_process_fd() uses that type for two of + the arguments. + +* May 25 2007 + +- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows + that could cause it to return a bad return code. + +* April 16 2007 + +- Yang Tse: Provide ares_getopt() command-line parser function as a source + code helper function, not belonging to the actual c-ares library. + +* February 19 2007 + +- Vlad Dinulescu added ares_parse_ns_reply(). + +* February 13 2007 + +- Yang Tse: Fix failure to get the search sequence of /etc/hosts and + DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when + /etc/resolv.conf did not exist or was unable to read it. + +* November 22 2006 + +- Install ares_dns.h too + +- Michael Wallner fixed this problem: When I set domains in the options + struct, and there are domain/search entries in /etc/resolv.conf, the domains + of the options struct will be overridden. + +* November 6 2006 + +- Yang Tse removed a couple of potential zero size memory allocations. + +- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel) + broke in the 1.3.2 release. We should switch to a system where that file is + auto-generated. We could rip some code for that from curl... + +Version 1.3.2 (November 3, 2006) + +* October 12 2006 + +- Prevent ares_getsock() to overflow if more than 16 sockets are used. + +* September 11 2006 + +- Guilherme Balena Versiani: I noted a strange BUG in Win32 port + (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network + by hand or disconnect the network cable in Windows 2000 or Windows XP, my + application gets 127.0.0.1 as the only name server. The problem comes from + 'GetNetworkParams' function, that returns the empty string "" as the only + name server in that case. Moreover, the Windows implementation of + inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE. + +* August 29 2006 + +- Brad Spencer did + + o made ares_version.h use extern "C" for c++ compilers + o fixed compiler warnings in ares_getnameinfo.c + o fixed a buffer position init for TCP reads + +* August 3 2006 + +- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and + not always zero! + +Version 1.3.1 (June 24, 2006) + +* July 23, 2006 + +- Gisle Vanem added getopt() to the ahost program. Currently accepts + only [-t {a|aaaa}] to specify address family in ares_gethostbyname(). + +* June 19, 2006 + +- (wahern) Removed "big endian" DNS section and RR data integer parser + macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise + operations in C operate on logical values. And in any event the octets are + already in big-endian (aka network) byte order so they're being reversed + (thus the source of the breakage). + +* June 18, 2006 + +- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls + from area_process.c. + + TODO: Handle one last EAGAIN for a UDP socket send(2) in + ares__send_query(). + +* May 10, 2006 + +- Bram Matthys brought my attention to a libtool peculiarity where detecting + things such as C++ compiler actually is a bad thing and since we don't need + that detection I added a work-around, much inspired by a previous patch by + Paolo Bonzini. This also shortens the configure script quite a lot. + +* May 3, 2006 + +- Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes + c-ares call a callback on socket state changes. A better way than the + ares_getsock() to get full control over the socket state. + +* January 9, 2006 + +- Alexander Lazic improved the getservbyport_r() configure check. + +* January 6, 2006 + +- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS + variable for easier controlling what it does and how it runs. + +* January 5, 2006 + +- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it + build with newer gcc versions that no longer defines "riscos". + +* December 22 + +- Daniel Stenberg added ares_getsock() that extracts the set of sockets to + wait for action on. Similar to ares_fds() but not restricted to using + select() for the waiting. + +* November 25 + +- Yang Tse fixed some send() / recv() compiler warnings + +* September 18 + +- Added constants that will be used by ares_getaddrinfo + +- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it + is available to ensure it works properly in a threaded environment. + +* September 10 + +- configure fix for detecting a member in the sockaddr_in6 struct which failed + on ipv6-enabled HP-UX 11.00 + +Version 1.3.0 (August 29, 2005) + +* August 21 + +- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info() + when getting the DNS server etc. + +* June 19 + +- Added some checks for the addrinfo structure. + +* June 2 + +- William Ahern: + + Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a + read event can come back from poll() on a valid SOCK_DGRAM socket but + recv(2) will still block. This patch doesn't ignore EAGAIN in + read_udp_packets(), though maybe it should. (This patch was edited by Daniel + Stenberg and a new configure test was added (imported from curl's configure) + to properly detect what non-blocking socket approach to use.) + + I'm not quite sure how this was happening, but I've been seeing PTR queries + which seem to return empty responses. At least, they were empty when calling + ares_expand_name() on the record. Here's a patch which guarantees to + NUL-terminate the expanded name. The old behavior failed to NUL-terminate if + len was 0, and this was causing strlen() to run past the end of the buffer + after calling ares_expand_name() and getting ARES_SUCCESS as the return + value. If q is not greater than *s then it's equal and *s is always + allocated with at least one byte. + +* May 16 + +- Added ares_getnameinfo which mimics the getnameinfo API (another feature + that could use testing). + +* May 14 + +- Added an inet_ntop function from BIND for systems that do not have it. + +* April 9 + +- Made sortlist support IPv6 (this can probably use some testing). + +- Made sortlist support CIDR matching for IPv4. + +* April 8 + +- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist + does not work with IPv6. Also provided an implementation of bitncmp from + BIND for systems that do not supply this function. This will be used to add + IPv6 support to sortlist. + +- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family. + The function can lookup IPv6 addresses both from files (/etc/hosts) and + DNS lookups. + +* April 7 + +- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac + OS X. + +* April 5 + +- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton + from BIND for systems that do not include these functions. + +* March 11, 2005 + +- Dominick Meglio added ares_parse_aaaa_reply.c and did various + adjustments. The first little steps towards IPv6 support! + +* November 7 + +- Fixed the VC project and makefile to use ares_cancel and ares_version + +* October 24 + +- The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw. + This is now fixed. + +Version 1.2.1 (October 20, 2004) + +* September 29 + +- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital + when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for + other OSes. He made c-ares check for and understand it if present. + +- Now c-ares will use local host name lookup _before_ DNS resolving by default + if nothing else is told. + +* September 26 + +- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf + file to determine the sequence in which to search /etc/hosts and DNS. So on + systems where this order is defined by /etc/host.conf instead of a "lookup" + entry in /etc/resolv.conf, c-ares will always default to looking in DNS + first, and /etc/hosts second. + + c-ares now looks at + + 1) resolv.conf (for the "lookup" line); + 2) nsswitch.fon (for the "hosts:" line); + 3) host.conf (for the "order" line). + + First match wins. + +- Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is + located in a static location. It assumed + C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact, + the location of the HOSTS file can be changed via a registry setting. + + There is a key called DatabasePath which specifies the path to the HOSTS + file: + http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx + + The patch will make c-ares correctly consult the registry for the location + of this file. + +* August 29 + +- Gisle Vanem fixed the MSVC build files. + +* August 20 + +- Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack. + +* August 13 + +- Harshal Pradhan made a minor syntax change in ares_init.c to make it build + fine with MSVC 7.1 + +* July 24 + +- Made the lib get built static only if --enable-debug is used. + +- Gisle Vanem fixed: + + Basically in loops like handle_errors(), 'query->next' was assigned a local + variable and then query was referenced after the memory was freed by + next_server(). I've changed that so next_server() and end_query() returns + the next query. So callers should use this ret-value. + + The next problem was that 'server->tcp_buffer_pos' had a random value at + entry to 1st recv() (luckily causing Winsock to return ENOBUFS). + + I've also added a ares_writev() for Windows to streamline the code a bit + more. + +* July 20 +- Fixed a few variable return types for some system calls. Made configure + check for ssize_t to make it possible to use that when receiving the send() + error code. This is necessary to prevent compiler warnings on some systems. + +- Made configure create config.h, and all source files now include setup.h that + might include the proper config.h (or a handicrafted alternative). + +- Switched to 'ares_socket_t' type for sockets in ares, since Windows don't + use 'int' for that. + +- automake-ified and libool-ified c-ares. Now it builds libcares as a shared + lib on most platforms if wanted. (This bloated the size of the release + archive with another 200K!) + +- Makefile.am now uses Makefile.inc for the c sources, h headers and man + pages, to make it easier for other makefiles to use the exact same set of + files. + +- Adjusted 'maketgz' to use the new automake magic when building distribution + archives. + +- Anyone desires HTML and/or PDF versions of the man pages in the release + archives? + +* July 3 +- Günter Knauf made c-ares build and run on Novell Netware. + +* July 1 +- Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp + fixes and made ares not use 'errno' to provide further info on Windows. + +* June 30 +- Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack. + +* June 10 +- Gisle Vanem's init patch for Windows: + + The init_by_resolv_conf() function fetches the DNS-server(s) + from a series of registry branches. + + This can be wrong in the case where DHCP has assigned nameservers, but the + user has overridden these servers with other prefered settings. Then it's + wrong to use the DHCPNAMESERVER setting in registry. + + In the case of no global DHCP-assigned or fixed servers, but DNS server(s) + per adapter, one has to query the adapter branches. But how can c-ares know + which adapter is valid for use? AFAICS it can't. There could be one adapter + that is down (e.g. a VPN adapter). + + So it's better to leave this to the IP Helper API (iphlapi) available in + Win-98/2000 and later. My patch falls-back to the old way if not available. + +* June 8 +- James Bursa fixed an init issue for RISC OS. + +* May 11 +- Nico Stappenbelt reported that when processing domain and search lines in + the resolv.conf file, the first entry encountered is processed and used as + the search list. According to the manual pages for both Linux, Solaris and + Tru64, the last entry of either a domain or a search field is used. + + This is now adjusted in the code + +Version 1.2.0 (April 13, 2004) + +* April 2, 2004 +- Updated various man pages to look nicer when converted to HTML on the web + site. + +* April 1, 2004 +- Dirk Manske provided a new function that is now named ares_cancel(). It is + used to cancel/cleanup a resolve/request made using ares functions on the + given ares channel. It does not destroy/kill the ares channel itself. + +- Dominick Meglio cleaned up the formatting in several man pages. + +* March 30, 2004 +- Dominick Meglio's new ares_expand_string. A helper function when decoding + incoming DNS packages. + +- Daniel Stenberg modified the Makefile.in to use a for loop for the man page + installation to improve overview and make it easier to add man pages. + +Version 1.1.0 (March 11, 2004) + +* March 9, 2004 +- Gisle Vanem improved build on Windows. + +* February 25, 2004 +- Dan Fandrich found a flaw in the Feb 22 fix. + +- Added better configure --enable-debug logic (taken from the curl configure + script). Added acinclude.m4 to the tarball. + +* February 23, 2004 +- Removed ares_free_errmem(), the function, the file and the man page. It was + not used and it did nothing. + +- Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of + compiler warnings on picky compilers. + +* February 22, 2004 +- Dominick Meglio made ares init support multiple name servers in the + NameServer key on Windows. + +* February 16, 2004 +- Modified ares_private.h to include libcurl's memory debug header if + CURLDEBUG is set. This makes all the ares-functions supervised properly by + the curl test suite. This also forced me to add inclusion of the + ares_private.h header in a few more files that are using some kind of + memory-related resources. + +- Made the makefile only build ahost and adig if 'make demos' is used. + +* February 10, 2004 +- Dirk Manske made ares_version.h installed with 'make install' + +* February 4, 2004 +- ares_free_errmem() is subject for removal, it is simply present for future + purposes, and since we removed the extra parameter in strerror() it won't + be used by c-ares! +- configure --enable-debug now enables picky compiler options if gcc is used +- fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk + reported + +Version 1.0.0 (February 3, 2004) + +* February 3, 2004 +- now we produce the libcares.a library instead of the previous libares.a + since we are no longer compatible + +* February 2, 2004 + +- ares_strerror() has one argument less.

If it returns successfully, \fBares_init\fP will set the +variable pointed to by \fIchannelptr\fP to a handle used to identify the name +service channel. The caller should invoke +.BR ares_destroy (3) +on the handle when the channel is no longer needed. +.PP +The \fBares_init_options\fP function also initializes a name service channel, +with additional options useful for applications requiring more control over +name service configuration. The \fIoptmask\fP parameter 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_PORT +.B unsigned short \fIport\fP; +.br +The port to use for queries (both TCP and UDP), 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. +.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. +.SH RETURN VALUES +.I ares_init +or +.I ares_init_options +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, +.BR ares_init (3) +reads the +.I domain +and +.I search +directives to allow lookups of short names relative to the domains +specified. The +.I domain +and +.I search +directives override one another. If more that one instance of either +.I domain +or +.I search +directives is specified, the last occurence wins.
