David Drysdale	87ff25049c	Mark unhittable lines Add comments for the benefit of the lcov tool, marking lines that cannot be hit. Typically these are fall-back protection arms that are already covered by earlier checks, and so it's not worth taking out the unhittable code (in case someone changes the code between the two places in future).	9 years ago
David Drysdale	fa14ba7b11	process_answer: fix things up correctly when removing EDNS option When a server rejects an EDNS-equipped request, we retry without the EDNS option. However, in TCP mode, the 2-byte length prefix was being calculated wrong -- it was built from the answer length rather than the length of the original request. Also, it is theoretically possible that the call to realloc() might change the data pointed to; to allow for this, qbuf also needs updating. (Both these fixes were actually included in a patchset sent on the mailing list in Oct 2012, but were included with other functional changes that didn't get merged: http://c-ares.haxx.se/mail/c-ares-archive-2012-10/0004.shtml)	9 years ago
Daniel Stenberg	ab78ef369d	read_tcp_data: don't try to use NULL pointer after malloc failure CID 56884, pointed out by Coverity. We really should make this function return an error code so that a malloc() failure can return back a major failure.	9 years ago
Daniel Stenberg	51dae48ecf	configure_socket: explicitly ignore return code CID 56889 in Coverity pointed out the return code from setsocknonblock() is ignored, and this added typecast to (void) makes it explicit.	9 years ago
Guenter Knauf	c8ec633bf5	Fixed warning 'type specifier missing'.	12 years ago
Daniel Stenberg	efdd616118	timeoffset: made static and private ares__timeoffset() was only used once within this single source file	12 years ago
Daniel Stenberg	30c9031afa	timeadd: make static ares__timeadd() was only ever used from within the same source	12 years ago
Daniel Stenberg	3217c7eef2	ares__swap_lists: make private and static ... since there's only one user, make it static within ares_process.c	12 years ago
Yang Tse	0c677f578e	setup_once.h: refactor inclusion of <unistd.h> and <sys/socket.h> Inclusion of these two header files now done in setup_once.h	12 years ago
Yang Tse	a1035276c1	Header inclusion clean-up Remove header inclusions already done in setup_once.h	12 years ago

Daniel Stenberg	e447bc5c60	code police: fix indents, < 80 columns, reflowed comments	13 years ago
Gisle Vanem	4d91235900	read_udp_packets: bail out loop on bad sockets I can see that recvfrom() in ares_process.c many times is called with 'udp_socket' == ARES_SOCKET_BAD. The code takes care not to call recv/recvfrom with ARES_SOCKET_BAD in the outer-loop. So should the inner-loop.	13 years ago
Yang Tse	38b69b7269	Kill compiler warning	13 years ago
Yang Tse	66e91438c5	ares_process.c: fix compiler warning	14 years ago

David Stuart	6518b56a5e	IPv6-on-windows: find DNS servers correctly	14 years ago
Yang Tse	8c503ddf79	System's errno.h inclusion cleanup. System's errno.h is conditionally included from setup_once.h	14 years ago
Daniel Stenberg	366cd6d54d	advance_tcp_send_queue: avoid NULL ptr dereference If given a too large 'num_bytes' value, it would cause a NULL ptr dereference. Instead the code will now break out of the loop at the end of the list.	14 years ago
Yang Tse	10ae9e4ec2	Fix GCC 4 compiler warning 'dereferencing type-punned pointer might break strict-aliasing rules'.	14 years ago
Yang Tse	4ab5eb6631	Revert commit `494274e653`	14 years ago
Yang Tse	494274e653	Fix GCC 4 compiler warning 'dereferencing type-punned pointer might break strict-aliasing rules'.	14 years ago
Yang Tse	747981be8e	Revert following commits: `07bc7ea795` `3392a50ea3` `9912637d32` The purpose of the whole patch was to silence a compiler warning triggered with GCC 4 on file ares_process.c The specific compiler warning was 'dereferencing type-punned pointer might break strict-aliasing rules'. A simpler patch will follow to equally silence the warning.	14 years ago
Ben Greear	9912637d32	sock-addr-storage: Detect and deal with lack of .ss_family member. AIX, at least, does not have sockaddr_storage.ss_family member. Detect this in the configure logic and use proper #ifdefs in the ares_process logic. Signed-off-by: Ben Greear <greearb@candelatech.com> Tested-by: Tor Arntsen <tor@spacetec.no>	15 years ago
Ben Greear	3392a50ea3	typo: Fix compile bug for platforms that don't have sockaddr_storage. Bug was introduced by me in previous commit. Signed-off-by: Ben Greear <greearb@candelatech.com>	15 years ago
Ben Greear	07bc7ea795	Fix aliasing warning in gcc 4.4.4 (at least). Should be no functional change, though the code gets a bit ugglier. Signed-off-by: Ben Greear <greearb@candelatech.com>	15 years ago
Ben Greear	3e33e2c2ba	ipv6: Fix some build issues related to the local-bind feature. Signed-off-by: Ben Greear <greearb@candelatech.com>	15 years ago
Ben Greear	e3b04e5a47	local-bind: Support binding to local interface/IPs Add 3 new functions to set the local binding for the out-going socket connection, and add ares_set_servers_csv() to set a list of servers at once as a comma-separated string. Signed-off-by: Ben Greear <greearb@candelatech.com>	15 years ago
Daniel Stenberg	63627fa5ab	remove all $Id$ lines	15 years ago
Peter Pentchev	a83d892bb2	Fix a couple of typos and grammar nits.	15 years ago
Yang Tse	8fe746fcf2	Added IPv6 name servers support	15 years ago
Daniel Stenberg	8b6f71ce95	- Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't check for broken connections like ares_process() did. Based on that, I merged the two functions into a single generic one with two front-ends.	15 years ago
Yang Tse	58d9b0c1bd	- Fix configure_socket() to use ares_socket_t instead of int data type.	15 years ago
Yang Tse	10461d1414	Make usage of calloc()'s arguments consistent with rest of code base	15 years ago

Yang Tse	3a55bbebf1	Use build-time configured ares_socklen_t instead of socklen_t	16 years ago
Yang Tse	737707bf4b	fix compiler warning: implicit conversion shortens 64-bit value into a 32-bit value	16 years ago
Phil Blundell	977de8c778	- ares__send_query() now varies the retry timeout pseudo-randomly to avoid packet storms when several queries were started at the same time.	16 years ago
Daniel Stenberg	f61fa37f40	Gregor Jasny provided the patch that introduces ares_set_socket_callback(), and I edited it to also get duped by ares_dup().	16 years ago
Dan Fandrich	36a6a6e175	Only set TCP_NODELAY when it exists	16 years ago
Yang Tse	65cafbe109	Refactor configure script detection of functions used to set sockets into non-blocking mode, and decouple function detection from function capability.	17 years ago
Daniel Stenberg	1a1b4eb4f2	- 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	17 years ago
Yang Tse	64c82d0853	Charles Hardin patch: - handles the EINPROGRESS for UDP connects - uses closesocket instead of close on some paths that were noticed	17 years ago

Yang Tse	c035f2d3a4	Functionality only possible if recvfrom() is available.	17 years ago
