2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker1-1/+1
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.

2012-04-01improve name lookup performance in corner casesRich Felker1-1/+1
the buffer in getaddrinfo really only matters when /etc/hosts is huge, but in that case, the huge number of syscalls resulting from a tiny buffer would seriously impact the performance of every name lookup. the buffer in __dns.c has also been enlarged a bit so that typical resolv.conf files will fit fully in the buffer. there's no need to make it so large as to dominate the syscall overhead for large files, because resolv.conf should never be large.
2011-08-01port numbers should always be interpreted as decimalRich Felker1-1/+1
per POSIX and RFC 3493: If the specified address family is AF_INET, AF_INET6, or AF_UNSPEC, the service can be specified as a string specifying a decimal port number. 021 is a valid decimal number, therefore, interpreting it as octal seems to be non-conformant.
2011-04-20disallow blank strings as service or host nameRich Felker1-0/+3
2011-04-08return the requested string as the "canonical name" for numeric addressesRich Felker1-0/+1
previously NULL was returned in ai_canonname, resulting in crashes in some callers. this behavior was incorrect. note however that the new behavior differs from glibc, which performs reverse dns lookups. POSIX is very clear that a reverse DNS lookup must not be performed for numeric addresses.
2011-03-25fix all implicit conversion between signed/unsigned pointersRich Felker1-1/+1
sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required.
