Yang Tse	a15a88a4e6	Avoid a segfault when generating a DNS "Transaction ID" in internal function init_id_key() under low memory conditions.	17 years ago
Steinar H. Gunderson	04e49e09dc	Previously, processing a large batch of timeouts was O(n^2) in the number of 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.	17 years ago
Steinar H. Gunderson	56ffdcefe1	Support a few more socket options, and refactor the option setting a bit. (Patch from the Google tree.)	17 years ago
Steinar H. Gunderson	b669e17544	Three fixes in one commit (sorry): a) Take care of the tcpbuf if it ends 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.	17 years ago
Daniel Stenberg	2b43edc964	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.	17 years ago
Daniel Stenberg	ad734e7b2d	Brad House's fix to hish a win32 compiler warning	18 years ago
Daniel Stenberg	403b315a3b	Vlad Dinulescu fixed two outstanding valgrind reports	18 years ago

Daniel Stenberg	fc5a460e0e	Brad Spencer found and fixed three flaws in the code, found with the new gcc 4.2.0 warning: -Waddress	18 years ago
Daniel Stenberg	49fdeb1de4	first take at detecting a random device and seeding the random key using data from it in randomize_key()	18 years ago
Daniel Stenberg	7a77f24d26	Shmulik Regev brought cryptographically secure transaction IDs	18 years ago
Daniel Stenberg	f1440b2405	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.	18 years ago
Daniel Stenberg	557aad7b02	Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows that could cause it to return a bad return code.	18 years ago
Gisle Vanem	a627160041	Removed inclusion of <sys/types.h> in .c-files since it's already included through "setup.h".	18 years ago
Yang Tse	679a675660	add debug messages for initialization failures	18 years ago
Yang Tse	69fa447354	use macros ERRNO, SET_ERRNO(), SOCKERRNO and SET_SOCKERRNO() for errno handling	18 years ago
Yang Tse	5dceb6d883	Oops, missing argument separator comma	18 years ago
Yang Tse	8c76cf38a7	in debug messages also show error description	18 years ago
Yang Tse	6751a208d6	Fix c-ares failing 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.	18 years ago
Gisle Vanem	657c69ce9d	Added HAVE_PROCESS_H for DOS/Win32. Include <process.h> for getpid() in ares_init.c.	18 years ago
Yang Tse	6f872e206a	add debug messages for initialization failures	18 years ago
Yang Tse	fb38ee15e2	compiler warning fix	18 years ago
Daniel Stenberg	6a59182e81	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.	18 years ago
Yang Tse	877966659d	avoid a couple of potential zero size memory allocations	18 years ago
Yang Tse	dd3b42e1ac	Replace is() macros with our own IS() ones. Get rid of non ANSI/ISO isascii().	18 years ago
Daniel Stenberg	d3439e3332	- 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.	18 years ago
Gisle Vanem	f417f06ca9	Added CVS id.	19 years ago
Gisle Vanem	a5c01eed75	If CURLDEBUG defined, call curl_memdebug() if $CARES_MEMDEBUG is set.	19 years ago
Daniel Stenberg	22e34b53e4	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.	19 years ago
Daniel Stenberg	d07656e76d	James Bursa fixes: find the hosts file on RISC OS, and made it build with newer gcc versions that no longer defines "riscos".	19 years ago
Daniel Stenberg	a8bb249d07	Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info() when getting the DNS server etc.	20 years ago
Daniel Stenberg	be551e6a00	killed trailing whitespace, narrowed a few lines to 80 cols	20 years ago
Daniel Stenberg	86661ab646	sortlist_alloc() is never used on win32, so ifdef out it to prevent warning	20 years ago
Daniel Stenberg	c0eb11ec6c	avoid warning on windows	20 years ago
Dominick Meglio	7012fc65d9	Made sortlist support IPv6 (this can probably use some testing)	20 years ago

Daniel Stenberg	994f16d733	untabified	20 years ago
Gisle Vanem	6c64cc8669	Replace IsNT with IS_NT(). Return correct timeval in windows_port.c. Squelch gcc warnings: use 'ares_socket_t' in ares_fds.c. Don't cast a 'lvalue' in ares_init.c.	20 years ago
Daniel Stenberg	3e748f4b50	removed tabs and trailing whitespace from source	20 years ago
Daniel Stenberg	47bd7d7548	- 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.	20 years ago
Daniel Stenberg	405d83852a	- 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.	20 years ago
Gisle Vanem	6deb40acac	Changes for Watt-32 on Windows. I've assumed Configure sets the required HAVE_xx defines for non-DOS/Win targets.	21 years ago
Daniel Stenberg	5d6bdc38cb	Harshal Pradhan made minor syntax change to make this build with MSVC 7.1	21 years ago
Daniel Stenberg	d5f3636a52	- 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.	21 years ago
Daniel Stenberg	cb0a33076a	Gisle Vanem made this build fine with djgpp and the Watt-32 stack.	21 years ago
