Revision history for Socket-GetAddrInfo

0.21 BUGFIXES:

• Exporter 5.57 is required - this has shipped with perl since 5.8.3, but now explicitly declared for 5.6.2
• getservbyport() needs a protocol name on 5.6.2

0.20 CHANGES:

• Added bin/getaddrinfo and bin/getnameinfo script (replaces previous examples/gai.pl)
• Split Socket6api into its own module
• Emulate AI_NUMERICSERV in PP emulation since most OSes in practice support it, even though RFC 2553 doesn't define it
• Provide Exporter tags for named constants
• Don't even attempt to build XS code if no C compiler is available
• Try to use core's Socket::getaddrinfo if it exists; as it does on Socket 1.93 (perl 5.13.9).
• Avoid Test::Exception and Test::Warn as they're non-core and pull in Sub::UpLevel
• Use ExtUtils::CChecker 0.06's ability to write a config.h rather than using C commandline -DFOO that might not be portable
• Moved legacy resolver emulation code into its own PP.pm for code neatness

  BUGFIXES

• Bugfix for non-C99 compilers - avoid C99-style struct initialiser
• Bugfix for threaded perls - aTHX/pTHX in err_to_SV()
• More MSWin32 fixes [rurban]
• Use ppport.h

0.19 BUGFIXES:

• Can't store &PL_sv_undef in an HV; store newSV(0) instead
• Handle magic in getaddrinfo() args [chansen]
• Win32 build fixes [chansen]

0.18 BUGFIXES:

• Fix plain number passing for getaddrinfo()'s service on perl versions <5.10.0

0.17 BUGFIXES:

• Fix 'protocol' hint to getaddrinfo()

0.16 CHANGES:

• Accept undef as absent host/service name, as well as ""

  BUGFIXES

• Need -lsocket on some OSes; hunt it using ExtUtils::CChecker

0.15 CHANGES:

• Use XSLoader instead of DynaLoader
• import Exporter::import instead of @ISAing it
• Use ExtUtils::CChecker for build checking

0.14 BUGFIXES:

• Don't leak memory on getnameinfo() failures
• Avoid possible sockaddr alignment errors by allocating/copying a new buffer (thanks to Zefram)

0.13 CHANGES:

• Don't warn if only importing symbolic constants; test this
• Added Test::Pod testing
• Docs neatening in L<> links

0.12 CHANGES:

• Added 'use warnings'
• Added 'gai.pl' example

0.11 CHANGES:

• Pass "socktype => SOCK_STREAM" hint in example
• Use "return 1" rather than "exit(1)" in C code to avoid needing <unistd.h>; may improve builds on non-UNIX platforms

  BUGFIXES

• Declare ExtUtils::CBuilder as a configure_requires dependency, and fail gracefully if it still isn't installed when Build.PL runs

0.10 BUGFIXES:

• Fixed a bug in getnameinfo() when handling IPv6 addresses, where a buffer overrun causes at least a failure from libc, but has the potential to cause a stack corruption or segfault.

0.09 CHANGES:

• Conditionally skip the tests for missing hostnames if the legacy resolver finds an address anyway. This may mitigate test FAILs on smoke test machines with wildcard DNS servers.

0.08 CHANGES:

• Declare as release

0.08_7 CHANGES:

• Make sure to sv_2mortal() returned SV*s in XS code

  BUGFIXES

• Minor changes to test scripts that should reduce cornercase FAILs, or at least help debug them if they occur

0.08_6 BUGFIXES:

• Set 'sa_len' member of sockaddr structure if platform needs it

0.08_5 BUGFIXES:

• Better comparison of sockaddr returns - unpack and test components to avoid errors on platforms that use sin_len, since Socket doesn't
• Use XSRETURN() in XS functions to ensure stack is correct height
• Better diagnostic if $err tests fail - convert number to symbolic constant

0.08_4 BUGFIXES:

• Define constants in XS code wrapped in #ifdef tests, to ensure only ones that the platform defines are attempted.
• Print whether PP or XS implementation are being used in the t/00use.t file

0.08_3 BUGFIXES:

• Use ExtUtils::CBuilder to compile the test .c file in the Configure() stage, to make it (hopefully) more portable
• Some OSes return $err==0 but no results for invalid names - make sure the test script can cope.

0.08_2 BUGFIXES:

• Declare variables in "PREINIT" XS section, not "INIT"; keeps non-C99 compilers happy
• Skip tests that require internet connectivity unless the tester declares it possible
• Declare test counts upfront in testing scripts
• Renamed XS functions 'getaddrinfo' and 'getnameinfo'; no need to prefix with 'real_'
• Folded Configure.pl inline into Build.PL, in case it has to make further decisions

0.08_1 CHANGES:

• Complete rewrite to XS+PP emulation system. No longer uses Socket6 on account of API and error reporting issues.
• Provided two styles of API at import time (:newapi and :Socket6api) to allow caller to choose between RFC2553-like or Socket6 styles

0.07 BUGFIXES:

• Ensure that emulated getaddrinfo() copes with family=AF_UNSPEC (0)

0.06 BUGFIXES:

• Avoid (harmless) "Constant subroutine .. redefined" warnings if 'use'd multiple times, when Socket6 is not available.

0.05 CHANGES:

• Reworded DESCRIPTION section of documentation
• Fixed some bugs in the SYNOPSIS example

0.04 BUGFIXES:

• Declare dependency on Test::Exception
• Fixed skip count in test in 01getaddrinfo-socket6.t

0.03 CHANGES:

• Changed getnameinfo() to avoid needing sockaddr_family(), which avoids a version check, which means it works on perl 5.6.1

0.02 BUGFIXES:

• Declare required version of Socket.pm sufficient to have sockaddr_family()

0.01 First version, released on an unsuspecting world.
