ChangeLog for Poslib <www.posadis.org/poslib>

Stable CVS
 * Initial cache file mode for master files no longer gives the "non-initial
   SOA ignored" message
 * Made ServerSocket virtual as it should have been
 * Made the server list a list of ServerSocket*'s rather than ServerSockets
   (thanks to the misdesign of the STL)
 * Added NONE/ANY values for classes/types required for DNS update
   (i.e. constant definitions and lexical function support)
 * Added support for empty records in case of DNS update messages
 * Fixed Borland C++ makefiles to fix requirement of a complete rebuild after
   changes
 * Fixed one-off (too conservative) error in DNS message reading
 * Made lower level DNS message functions (read/write RR) publicly available
 * Added rr_torelstring
 * Added txt_to_class
 * Removed extra trailing space in rr_to(rel)string
 * When SOA record is converted to string, TTL short notation (i.e. 2h) is used.
 * Reading master file without autoprobing: origin is set to zone root by
   default.
 * Added support for "none" IPv4 address, added addr_is_any and addr_is_none
   functions
 * Switched to pkg-config (removing the poslib-config script)
 * Default prefix /usr removed (i.e., will now be /usr/local)
 * Replaced yet more char*s by const char* 
 * Added support for .123. and .123 type domain names
 * Fixed bug in handling of unknown RRs
 * Renamed poslib-config.h to poslib.h (hope this doesn't break things)
 * Fixed bug in pthread detection, causing problems with OpenBSD.
 * Added rr_property_to_string, for more advanced RR-to-string functions
 * Mass-conversion char->unsigned char
 * Fixed bug where rr_getip6 would return only four bytes
 * Fixed bug in converting character strings and WKS records to string
 * Fixed bug in domain name compression (seems to have got lost along the way)

Version 1.0.5
 * Master file reader now allows you to skip certain checks to make it more
   useful for initial cache files.
 * Also accept ".dns" extension for master files
 * Win32 poll implementation: if we're not waiting for sockets, do timeout
   rather than direct return.

Version 1.0.4
 * Show zero TTL's as '0', not ''
 * Fixed error message for invalid TTLs
 * LOC (location) RR support
 * Fixed bug in master file reading when parsing comments in multi-line RRs
 * Fixed bug in master file where strange things would happen with commented
   parentheses

Version 1.0.3
 * Fixed bug where queries with the RD bit would be answered, possibly causing
   a flood in combination with IP spoofing. [Thanks to roy at dnss.ec]
 * Fixed bug where, if Posadis is at its max number of threads and it receives
   a message with size smaller than the buffer size, the ID with which an answer
   is sent back is wrong. [Thanks to dou0228 at msn.com]
 * Fixed bug where posthreads would neither be joined nor detached, causing
   a memory leak. [Thanks to dou0228 at msn.com]
 * Fix check for -lpthread on Linux
 * Fixed bug where "no threads left" error answer code would assert the
   question list being nonempty.
 * Made the fix for non-detached posthreads more Borland C++/pthreadVC.dll-proof
   (detaching a joined thread apparently results in undefined behavior; for
   Borland C++ this means a crash).
 * Removed erroneous in_addr6 references in Windows IPv6 code
 * Added poslib_config_init() function to reset config values
 * Made poslib/server/server.h include configuration.h
 * Added configuration.h to poslib/server/server.h
 * Fixed bug for <addr>/length-type IP ranges

Version 1.0.2
 * Changed occurences of "RR" in domain function error messages to
   "domain".
 * Fixed bug while attempting to refer to domain names with offset
   >= 16384 in DNS message (doesn't fit in compression pointer)
 * Now automagically set the ID of an answer message to the ID of the query
 * If truncation happens in answer or authority, also set item count of
   remaining sections to zero.
 * If we get an answer which is not truncated at a RR border with right
   AN,NS,AD-counts, we still accept the answer as truncated and retry the query
 * Made IPv6 work again with Borland C++
 * Fixed bug where masterfile.cpp would not be compiled along with Borland C++
 * Added more logically named addr_is_* alternatives to sock_is_*
 * Fixed bug causing pos_srvresolver to block if sending the query failed
   (this will probably only occur if the server sockets haven't been opened
   properly)
 * Fixed bug where the .dead:beeef extension to domain names would be postfixed
   by ipv6.int rather than ip6.int
 * For performance reasons, the configuration settings are now no longer
   protected by mutexes; if you want to set 'em, do it before starting the
   server thread.
 * Fixed bug where, if IPv6 support was enabled but no sockaddr_storage was
   available (Win32 systems, mainly), Posadis would use the smaller sockaddr
   structure, resulting in crashes if it was actually used.
 * Fixed problem where a completely empty master file gave an "Unexpected EOF"
   error.
 * The log implementation now flushes the log file after writing a message.
 * Fixed bug where exceptions in the cliresolver would not be correctly
   handled.
 * Now automagically try another server if a SRVFAIL, REFUSED or NOTIMP is
   found as an answer in pos_cliresolver.
 * Very simple, more efficient, possimplerandom() implementation
 * Grep s/authoritive/authoritative/
 * Enhanced pseudo-domain support: support ns1..dead::beef
 * Fixed problem with poslib-config with non-bash shells
 * Fixed typo: 'quites'->'quotes'
 * Added support for "y", "j" and "n" booleans
 * Added check_answer_type, has_rrset functions

Version 1.0.1
 * Put off optimisations by default (caused problems on FreeBSD)
 * Build fixes for FreeBSD
 * Fixed _really_ stupid bug where txt_to_bool would always return true
   (thanks to Aleksandr Chechulin)
 * Fixed bug causing TCP queries not to work in some cases
 * Made waiting for TCP data use end time rather than twice the half timeout.
 * Made txt_to_int only return nonnegative numbers, and make it not accept
   only postfixes anymore. Added txt_to_negint which also supports negative
   numbers.
 * Fixed problem in master file reader causing inexplicit domain names not
   to work.

Version 1.0
 * Added dnstimeago to Unix tarballs
 * Added stl_list variant of addrrange function
 * Fixed memory leak (thanks John MacDonald) in zero-byte allocations
 * Added posclient_quitflag to make socket functions end more quickly
 * Made UDP sockets SO_REUSEADDR as well

Version 0.9.7 (31 May 2003)
 * Fixed issue where addr_in_list(slist, ...) would not be available
   because pos6-config.h was not included.
 * Added option to include the function pointer logging functionality,
   but not use it yet by setting function pointer to NULL.
 * Fixed function pointer logging bug
 * Fixed w32poll: struct timeval uses microsec rather than millisec
   (causes 100% CPU usage under Windows)
 * Made standard logging variables available if POS_DEFAULTLOG is not
   defined (so that other source files can use then), and documented them.
 * Added decent vsnprintf() check for Unix (caused problems in logging)

Version 0.9.6 (23 May 2003)
 * Added address range class
 * Added str_ttl function
 * Poslib now sets the QR bit for you
 * Added in_addr_list function
 * Added postime_t::operator+=

   rather than current.
 * Support for literal "any" and "local" strings as IPv4/6 addresses.
 * Made pos_cliresolver::query() start at a random position in the
   query list.
 * Added support for IP ranges with netmasks
 * Threads amount limit
 * TCP connections limit/support for priority clients
 * Made UDP server sockets nonblocking
 * Added master file reading functionality
 * Fixed really stupid txt_to_email bug
 * Fixed POS_DEFAULTLOG_FILE (didn't work at all!)
 * added possimplerandom()

 * Fixed read_entry to support spaces and tabs within quotes
 * Replaced some instances of 'string' by 'stl_string' in fileclient and
   fileserver.

 * Fixed memory leak in DnsMessage::compile(), and other small leaks.
 * PACKAGE and VERSION are no longer in poslib-config.h
 * Now default flags=Q_DFL for 2nd pos_resolver::query() function in
   implementations.
 * Added read_line function from Pos6, which can really help master file
   reading routines.
 * Fixed txt_to_int to return correct "incorrect numeric value %s" message.
 * Fixed crash when copying an PException(). Additionally, PException("")
   now sets message to "" instead of NULL.
