+ * Do not spin if TCP connection blocks for writing (and add test case).
[adns] / changelog
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
14 Portability/compilation fixes:
15 * Move `extern "C" {' to after #include <...>'s.
16 * Pass LDFLAGS from configure on to ld via settings.make.in.
17 * make clean deletes *.so and *.so.* files.
18
19 Minor improvements:
20 * Do not print warning if sendto() gives EAGAIN.
21 * adnsresfilter default timeout changed to 1000ms.
22 * m1test script can invoke `hrecord' differently.
23 * regress/output-<case>.report file contains more useful info.

28
29 Bugfixes:
30 * Race near adns_beforeselect which could cause infinite timeout fixed
31 (it's now less agressive, and will more often return a zero timeout.)
32 * Fixed infrequent race causing assertion failure in adns__tcp_broken
33 `ads->tcpstate == server_connecting || ads->tcpstate == server_ok'.
34 * Spurious `server failure on unidentifiable query' warning suppressed.
35 * If we get a referral, don't also always complain falsely about RD==0.
36 * adnslogres: cast chars to unsigned char before using ctype.h macros.
37 * In _beforeselect, global failure now means zero timeout, and in
38 tcp_events, really never try to do anything with the TCP connection if
39 act is zero. This might possibly cause an infinite delay (ie, lockup)
40 if things go badly wrong *and* a really unlikely race happens.
41 * Test suite `lines of syscall left' value is correct; !0 is failure.
42
43 Portability fixes:
44 * install-sh (from autoconf 2.12 Debian r13) included.
45 * adnslogres: do not call equivalent of printf("%.*s",0,(char*)0).
46
47 Documentation improvements:
48 * Security/performance note added, about local nameservers and DNSSEC.
49 * Documented that adns_rr_info _rr_hostaddr ( ) for address list
50 means permanent failure, and ? means temporary failure.
51 * Typo (*now for now in _beforeselect description) in adns.h fixed.
52 * Copyright notices updated.
53
54 Changes to produce more defensive code:
55 * In adns_wait, assert that the timeout is not infinite.
56 * Make qu->id start out as -2 when initially allocated.

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

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

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

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

181 adns (0.3) unstable; urgency=low
182
183 Incompatible changes:
184 * Low adns_status values (below adns_s_max_tempfail) renumbered to make
185 room for future locally-induced and locally-detected errors.
186 * Event loop functions for use by select(2) renamed and tidied up.
187
188 Features / improvements:
189 * New adns_errabbrev() for getting status abbreviation strings.
190 * regress/checkall prints summary list of failed tests, if any.
191 * Event loop functions for poll(2), and some raw variants.
192 * adnstest has ability to use poll(2), and user can set initflags.
193 * checkall prints passed list as well as failed list, if any failed.
194 * You can iterate over outstanding queries (but only once at a time).
195
196 Bugfixes:
197 * Non-RFC822 mailbox `domain' formatting now works, and clarified.
198 * Rejection of bad characters in domains (without quoteok) works.
199 * Clean up parents from adns->childw (otherwise would abort/segfault).
200 * In adnstest, allocate enough space for, and terminate, query types.
201 * In adnstest, don't print errno values as adns_status values.
202
203 * Added TODO file.
204 * Made adnstest.c test context pointers.

214 * Check whether we need -lsocket.
215 * Include <sys/times.h> in a few more files.
216 * Include <unistd.h> and <sys/time.h> for select.
217 * Look for inet_aton and inet_ntoa (in -lnsl and -lsocket).
218 * LDLIBS removed from dependency lists (some makes don't support this).
219 * An `ambiguous else' warning from some compilers in types.c is removed.
220
221 Other changes:
222 * Added COPYING (copy of the GPL).
223 * Regression test failure output improved.
224 * Missing targets in regress/Makefile.in added.
