Patch from Tup: treat RESOLVED_TYPE_ERROR_TRANSIENT as a SERVERFAILED, and RESOLVED_TYPE_ERROR as NOTEXIST. Generate transient/nontransient errors more sensibly. Set flags better on DNS replies.
svn:r10427
Fix handling of resolves with very long or otherwise malformed addresses, and comment dns_resolve better, and stop making what should be a BUG warning into an assert(0). This fixes bug 427, which was introduced around 9900/9931/9932. Not a backport candidate: 0.1.2.x never had this bug.
svn:r10399
Note a few questionable bits pointed out by RATS. (And no, RATS, I'm not about to stop having fixed-sized local buffers for you. I know how to use them, thankyouverymuch.)
svn:r9474
Add a couple of fixes I turned up while writing regression tests for libevent: Allow DNS servers on ports other than 53, and handle TTLs correctly on reverse hostname lookups.
svn:r9458
Apparently, the OpenBSD linker thinks it knows C better than I do, and gets to call me names for having strcat and strcpy and sprintf in my code--whether I use them safely or not. All right, OpenBSD. You win... this round.
svn:r9360
Resolve bug 363: do not fall back to 127.0.0.1 when no nameservers are configured. Instead, have the admin fix resolv.conf or configure a nameserver.
svn:r9157
Try to reconcile (except for whitespace) eventdns with version in libevent, so it is easier for me to send merges. These changes should be cosmetic. (Ha!)
svn:r9117
Document all structures and (non-exported) functions. External documentation will probably wind up being a manpage, hopefully written by somebody else.
svn:r9087
More evdns: tab fixes. Dont make users worry about flags. Set truncated flag correctly when generating responses, rather than just bailing out.
svn:r9084
Oops; apparently DNS replies are supposed to include the questions. Revise "add_ptr_reply" to accept an inaddr_arpa name instead of just the sockaddr_in. Also, add a "-servertest" function to the test code to see whether the DNS server logic is working.
svn:r9082
Fix a longstanding bug in eventdns related to timeouts: The timeout count was never actually reset to 0. Argh. Now we reset it to zero after we get a successful request, or after we notice that a nameserver is back up, or after we decide the nameserver is down because of timeouts. This may fix bug 326.
svn:r9054
Try to compile with fewer warnings on irix64's MIPSpro compiler /
environment, which apparently believes that:
- off_t can be bigger than size_t.
- only mean kids assign things they do not subsequently inspect.
I don't try to fix the "error" that makes it say:
cc-3970 cc: WARNING File = main.c, Line = 1277
conversion from pointer to same-sized integral type (potential portability
problem)
uintptr_t sig = (uintptr_t)arg;
Because really, what can you do about a compiler that claims to be c99
but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
is safe?
