2008-08-04- Fix by Tofu Linden:Daniel Stenberg
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.
2008-06-30- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define isDaniel Stenberg
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.
2008-05-15use same time source for timeout initialization and processingYang Tse
2008-05-13- Introducing millisecond resolution support for the timeout option. SeeDaniel Stenberg
ares_init_options()'s ARES_OPT_TIMEOUTMS.

2007-09-29Previously, processing a large batch of timeouts was O(n^2) in the number ofSteinar H. Gunderson
outstanding queries, and processing a DNS response packet was O(n) in the number of outstanding queries. To speed things up in Google, we added a few circular, doubly-linked lists of queries that are hash-bucketed based on the attributes we care about, so most important operations are now O(1). It might be that the number of buckets are higher than most people would need, but on a quick calculation it should only be 100kB or so even on a 64-bit system, so I've let it stay as-is.
2007-09-28Support a few more socket options, and refactor the option setting a bit. ↵Steinar H. Gunderson
(Patch from the Google tree.)
2007-09-28Three fixes in one commit (sorry): a) Take care of the tcpbuf if it ends ↵Steinar H. Gunderson
while queued for transmission, note broken servers and close them in the main loop, and store TCP socket generation number in order not to send the same query twice over the same socket.
2007-09-22Brad House provided a fix for ares_save_options(): Apparently I overlookedDaniel Stenberg
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.

2007-05-30Brad House added ares_save_options() and ares_destroy_options() that can beDaniel Stenberg
used to keep options for later re-usal when ares_init_options() is used.
2007-05-25Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windowsDaniel Stenberg
that could cause it to return a bad return code.
2007-02-26Removed inclusion of <sys/types.h> in .c-filesGisle Vanem
since it's already included through "setup.h".

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.

2006-11-22Michael Wallner fixed this problem: When I set domains in the optionsDaniel Stenberg
struct, and there are domain/search entries in /etc/resolv.conf, the domains of the options struct will be overridden.

2006-10-18Replace is*() macros with our own IS*() ones.Yang Tse
Get rid of non ANSI/ISO isascii().
2006-09-11- Guilherme Balena Versiani: I noted a strange BUG in Win32 portDaniel Stenberg
(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.

2006-05-03Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makesDaniel Stenberg
c-ares call a callback on socket state changes. A better way than the ares_getsock() to get full control over the socket state.
