   1 adns (0.9) unstable; urgency=high
   2
   3   Bug fixes:
   4   * Don't make _processany always kill the TCP connection with the message
   5     `TCP connection failed: poll/select: exceptional condition detected'.
   6   * Call MEM_ROUND in __transfer_interim (avoids assert fail
   7     `qu->interim_allocd>=0' on some platforms eg 64 bit).
   8   * adnsresfilter doesn't resolve textual prefixes of addresses (eg,
   9     10.0.0.1 out of 10.0.0.123) if input happens to block at that point.
  10   * Do not spin if TCP connection blocks for writing (and add test case).
  11   * Fail queries if TCP dies repeatedly, rather than retrying many times.
  12   * Do not abort in a couple of places if TCP unexpectedly broken.
  13   * Do not free something twice if query fails and is then cancelled.
  14
  15   Portability/compilation fixes:
  16   * Move `extern "C" {' to after #include <...>'s.
  17   * Pass LDFLAGS from configure on to ld via settings.make.in.
  18   * make clean deletes *.so and *.so.* files.
  19
  20   Minor improvements:
  21   * Do not print warning if sendto() gives EAGAIN.
  22   * adnsresfilter default timeout changed to 1000ms.
  23   * m1test script can invoke `hrecord' differently.
  24   * regress/output-<case>.report file contains more useful info.
  25   * TODO list updated somewhat.

  30
  31   Bugfixes:
  32   * Race near adns_beforeselect which could cause infinite timeout fixed
  33     (it's now less agressive, and will more often return a zero timeout.)
  34   * Fixed infrequent race causing assertion failure in adns__tcp_broken
  35     `ads->tcpstate == server_connecting || ads->tcpstate == server_ok'.
  36   * Spurious `server failure on unidentifiable query' warning suppressed.
  37   * If we get a referral, don't also always complain falsely about RD==0.
  38   * adnslogres: cast chars to unsigned char before using ctype.h macros.
  39   * In _beforeselect, global failure now means zero timeout, and in
  40     tcp_events, really never try to do anything with the TCP connection if
  41     act is zero.  This might possibly cause an infinite delay (ie, lockup)
  42     if things go badly wrong *and* a really unlikely race happens.
  43   * Test suite `lines of syscall left' value is correct; !0 is failure.
  44
  45   Portability fixes:
  46   * install-sh (from autoconf 2.12 Debian r13) included.
  47   * adnslogres: do not call equivalent of printf("%.*s",0,(char*)0).
  48
  49   Documentation improvements:
  50   * Security/performance note added, about local nameservers and DNSSEC.
  51   * Documented that adns_rr_info _rr_hostaddr ( ) for address list
  52     means permanent failure, and ? means temporary failure.
  53   * Typo (*now for now in _beforeselect description) in adns.h fixed.
  54   * Copyright notices updated.
  55
  56   Changes to produce more defensive code:
  57   * In adns_wait, assert that the timeout is not infinite.
  58   * Make qu->id start out as -2 when initially allocated.

  61
  62 adns (0.7) BETA; urgency=medium
  63
  64   * New adns_submit_reverse_any for eg RBL lookups, and corresponding
  65     option to adnshost.
  66   * README updated (from www home page).
  67
  68   * In answers, quote all except alphanums and - _ / + (and document).
  69   * Don't reject specials in cnames even without adns_qf_quotefail_cname.
  70   * Better checking of long domain names and labels in queries.
  71   * answer->owner may be null on error.  Documented, and adnshost copes.
  72   * Better reporting of unexpected or weird replies from nameserver.
  73   * Add test case for recursion (infinite loop) domain compression.

  76
  77 adns (0.6) BETA; urgency=high
  78
  79   Core library bugfixes:
  80   * Avoid infinite timeouts, causing lockup, when they should be zero !
  81   * TCP handling revamped (avoids undefined behaviour due to reentrancy).
  82   * Do not fail assertion if _qf_owner, _qf_search, domain ends in `.'.
  83   * Many memory leaks fixed.
  84
  85   Cool new utility:
  86   * adnsresfilter is like `cat' but converts addresses to names without
  87     delaying the output.  Pipe `netstat -n', `tcpdump -ln', etc. into it.
  88
  89   Test and client program bug and portability fixes:
  90   * Dynamic library building works properly.
  91   * adnshost prints somewhat better messages about some wrong usages.
  92   * Include <stdlib.h> and <sys/types.h> in adnshost.h.
  93   * adnslogres: parsing and error checking improved (Tony Finch).
  94   * Regression tests can cope with zero-length reads.
  95   * Regression tests check for memory leaks.
  96   * adnstest copes with empty query type list.
  97   * adnstest uninitialised memory bug fixed.
  98
  99   General improvements
 100   * Better control of adnshost output and error messages (new -F options).
 101   * New adns_if_logpid option (functionality suggested by Tony Finch).
 102   * New fanftest test program from Tony Finch (ignored by `make install').
 103   * Reads /etc/resolv-adns.conf if it exists.
 104   * Declare flags parameters as enums again, not ints.

 107
 108 adns (0.5) unstable; urgency=high
 109
 110   New features:
 111   * adnslogres, ~100x faster replacement for Apache logresolve;
 112     Thanks to Tony Finch for the program and the performance figure.
 113   * Internal consistency checking with assert if right options set.
 114   * adns_wait_poll function like adns_wait but uses poll, not select.
 115   * adns_reverse_submit function for easy in-addr queries.
 116   * adns_errtypeabbrev funcion for getting eg "permfail" from _s_nodata.
 117   * adnshost utility for scripts and the like (rather alpha).
 118
 119   Incompatible changes:
 120   * RRs with mailboxes never rejected due to strange chars if _raw.
 121   * Lack of a mailbox produces `.' not `<>'.
 122   * Better usage messages (and no default query domain) for adnstest.
 123   * Return EAGAIN from _check instead of EWOULDBLOCK.
 124   * adns_rr_info on _r_mx etc. shows status type abbrev and status number.
 125
 126   Bugfixes:
 127   * Do not invoke __autosys indirectly from __procdgram (result: coredump
 128     usually in memmove, unless adns_if_noautosys was used).
 129   * Do not scramble innards when a query on the output queue is cancelled.
 130   * Do not close tcp socket twice.
 131   * Mailboxes containing spaces in their names are quoted.
 132   * Give ESRCH, not EAGAIN, if _check called with no queries outstanding.
 133   * adns_rr_hostaddr naddrs is -1 on temporary failure (as documented).
 134   * Reject TXT RRs with no strings.
 135   * Correct error messages for qname CNAME foo, foo CNAME bar.
 136   * adns_processany actually does something.
 137   * Fixed typos in adns.h.
 138
 139   General improvements:
 140   * Promise not to change fds in adns_beforepoll (if now is specified).
 141   * Improved textual error string for _s_prohibitedcname.
 142   * New comment in adns_processany and return 0 (not r which is 0).
 143   * Documentation of resolv.conf directives and options, and of environment
 144     variables understood, in adns.h
 145   * Regression test scripts set EF_DISABLE_BANNER (for Electric Fence).
 146
 147   Portability and build improvements:
 148   * Give install the '-c' flag (otherwise some delete the original !).
 149   * Do not remove top-level Makefile on `make clean'.
 150   * Don't complain so much about poll(2) tests if not available.
 151   * Do not give -u 0 -g 0 options to install.
 152   * Remove trailing , from some enums in adns.h.
 153   * Dynamically linked clients now made with -l, so as to avoid rpath.
 154   * Do not use $^ in make rules (should help with non-GNU make).
 155   * Declare flags parameters as ints not enums because C++ is crap.

 159 adns (0.4) unstable; urgency=high
 160
 161   General important bugfixes:
 162   * make _qf_owner work if _qf_search not specified, and test it (oops!)
 163   * ads->configerrno now initialised (in setup.c).
 164   * timercmp(,,<=) doesn't work - use !timercmp(,,>).
 165   * Changed memory semantics of internal queries to fix bugs.
 166   * Restarting a TCP-using query (eg due to CNAME) doesn't abort.
 167
 168   Fixes for handling of broken kinds of reply:
 169   * Only accept a reply from the subset of servers we sent the query.
 170   * Ignore CNAME(s) in answer after RR(s) (and test).
 171
 172   Other bugfixes and improvements:
 173   * adns_s_systemfail is in table of errors (for eg adns_strerror).
 174   * Do not ship config.cache, Makefile, etc.
 175   * Improvements to install instructions, TODO, etc.
 176   * Regression tests compile on systems without poll(2).
 177   * Do not install adnstest_s.
 178   * _submit returns ENOSYS, not adns_s_unknownquery; documented, tested.
 179   * <adns.h> includes <sys/types.h>, <sys/time.h>, <unistd.h>.

 183 adns (0.3) unstable; urgency=low
 184
 185   Incompatible changes:
 186   * Low adns_status values (below adns_s_max_tempfail) renumbered to make
 187     room for future locally-induced and locally-detected errors.
 188   * Event loop functions for use by select(2) renamed and tidied up.
 189
 190   Features / improvements:
 191   * New adns_errabbrev() for getting status abbreviation strings.
 192   * regress/checkall prints summary list of failed tests, if any.
 193   * Event loop functions for poll(2), and some raw variants.
 194   * adnstest has ability to use poll(2), and user can set initflags.
 195   * checkall prints passed list as well as failed list, if any failed.
 196   * You can iterate over outstanding queries (but only once at a time).
 197
 198   Bugfixes:
 199   * Non-RFC822 mailbox `domain' formatting now works, and clarified.
 200   * Rejection of bad characters in domains (without quoteok) works.
 201   * Clean up parents from adns->childw (otherwise would abort/segfault).
 202   * In adnstest, allocate enough space for, and terminate, query types.
 203   * In adnstest, don't print errno values as adns_status values.
 204
 205   * Added TODO file.
 206   * Made adnstest.c test context pointers.

 210 adns (0.2) experimental; urgency=low
 211
 212   Portability fixes for compilation on various platforms:
 213   * Include <sys/socket.h> and <netinet/in.h> in files with <arpa/inet.h>.
 214   * Don't use GCC union assignment feature (.rrs=0 => .rrs.untyped=0).
 215   * Explictly cast things to [const] struct sockaddr* in syscall args.
 216   * Check whether we need -lsocket.
 217   * Include <sys/times.h> in a few more files.
 218   * Include <unistd.h> and <sys/time.h> for select.
 219   * Look for inet_aton and inet_ntoa (in -lnsl and -lsocket).
 220   * LDLIBS removed from dependency lists (some makes don't support this).
 221   * An `ambiguous else' warning from some compilers in types.c is removed.
 222
 223   Other changes:
 224   * Added COPYING (copy of the GPL).
 225   * Regression test failure output improved.
 226   * Missing targets in regress/Makefile.in added.
 227   * Regression test doesn't rely on value of fcntl flags eg O_NONBLOCK.
