Deliantra MORPG Server, Maps and Archetypes ChangeLog.

TODO: ridify us from FLAG_NO_FIX_PLAYER
TODO: picking up the torches in nimbus seemingly works, but after
      a while (used up?) they seem to be gone from the inv but the client doesn't know about that.
TODO: dragons should not be able to change their title via the settings tab in playerbook

        - reloading archetypes while a user was in the character creation phase
          could crash the server.
        - merge items with different arch pointers refering to the same arch
          (due to archetype reloads).
        - completely rewrite the weight handling, fixing a number of bugs.
        - refactored the object remove/insert functions.
        - make it compile better on freebsd (reported by pippijn).

2.51  Sun Apr 20 21:27:37 CEST 2008
        - properly link against libgthread as that is needed to make the slice
          allocator thread-safe.
        - support perls not compiled with 64 bit support (though this is not a
          recommended configuration) (reported by Samuel Gondouin).
        - always put godgiven items into the player inventory, never any containers.
        - (arch)
        - (maps, arch) the scorn go club was founded!
        - (arch) do no longer support player abilities, they didn't work anyways.
        - (arch) the alchemy spell is now of the alchemy spell school, which
          became a real spell-class.
        - (arch) the alchemist class now get an alchemy spell book for new characters.
        - (arch) considerably strengthened spark shower and destruction.
        - match archetypes by name, not by ptr, in treasure.C, this makes archetypes
          finally reloadable at runtime.
        - changed archetype loading algorithm to only require one pass and
          use delayed resolving of references.
        - examine command now uses the examine infobox.
        - implement an "incremental garbage collector" for archetypes.
        - enable slice allocator again.
        - implement optional free memory poisoning.

2.5  Wed Apr 16 15:06:53 CEST 2008
        - the two handed weapon skill can no longer be used as unarmed combat
          skill.
        - append [drop xxx coins] to altar/trigger_altar/identify_table/converter
          names (also update all maps to use money instead of coins).
        - add uuid accessors to perl.
        - add coin names and archetype accessors to perl.
        - fix runtime uuid file format to use "." instead of ",".
        - change perl extensions to not use hardcoded coins and values.
        - write uuids asynchronously (no hiccups due to uuid writes)
          and be more parsimonous of uuid usage by the exact value out on exit.
        - write log messages in another thread, removing another sync point.
        - support multi-line log messages in a nicer way.
        - be more portable w.r.t. uuids and format specifiers everywhere.
        - fix a minor memleak in the random map generator.
        - some parts of the random map generator are not coroutine-safe,
          so only call it "single-threaded".
        - major cleanup of memory management in random map generator.
        - slight refactoring of the random map generator, faster too.
        - solve the "slice_alloc becomes negative" mystery - no allocation bug,
          bookkeeping bug.
        - work around "player is on active list" problem by deactivating player
          after loading.
        - garbage collect shstr's more evenly and adaptively only when
          there have in fact been allocations.
        - fix object::insert to do as documented and insert into the env
          if necessary.

2.43 Sun Apr  6 20:35:29 CEST 2008
        - work around a glibc bug that causes calloc to return non-zero memory
          when mlockall has been used.
        - pass environment to perl_sys_init3, as required by newer perls.
        - use separate thread for ticker timing (and more in the future).
          this greatly increases timing accuracy and gets rid of an enourmous
          number of gettimeofday calls.
        - use a separate thread to signal aio completion, for lower latency.
        - require Coro 4.47, which fixes a data corruption bug with its C API.

2.42 Sat Mar 15 12:05:21 CET 2008
        - rebalanced default experience table to be more exponential
          and much easier up to level ~40, then moderately harder.
        - change attuned/repelled level boni to +-8 from +-2.
        - use SvUPGRADE to avoid exception in sv_upgrade with perl 5.10.
        - do not exit on reload/load errors but properly cleanup.

2.41 Fri Jan 25 13:15:37 CET 2008
        - get rid of YAML::Syck, it's too buggy and misparses many files
          (this fixes the jeweler skill).
        - back-to-back perl_reloads don't freeze the ticker anymore.
        - convert cfutil from Event to EV (forgot to do this earlier...).
        - move tombstone to real map if player died due to cave-in (even if
          it has reset, which is better than putting it on the savebed, also as
          proof that the palyer didn't use a savebed).

2.4  Sun Jan 13 13:41:29 CET 2008
        - work around perl bug in configure perl module version check.
        - fix bug in golem move code that would cause a crash at tiling borders.
        - fix a freeze bug when looking for an arrow in the inventory.
        - fix a bug in animate_weapon, causing a crash.
        - no longer exit when a coroutine throws an exception.
        - fix a potential double free bug (nicely exploited by g++ 4.2).
        - fix the "<player> is nuts" message.
        - fix an exception at logout due to the json_coder being gone.
        - upgrade to EV version 2.0 API.
        - when players don't apply a savebed correctly but stand above one,
          do not move or kill them.
        - implement client-side settings page in playerbook (0.9963+ required).
        - implement generic framework for server-side resource files.
        - implement resource file update event.
        - hook experience table update into the framework.
        - move jeweler.yaml to resources (arch/).
        - switch from Crossfire to Deliantra perl module.
        - implement json2json arch filter.
        - implement widget protocol version 2, support for ui templates.
        - mapinfo is now handled fully asynchronously.
        - ext/irc: also log irc messages.
        - ext/schmorplog: write user stat files asynchronously.

2.32 Sun Dec  2 18:11:01 CET 2007
        - limited the number of items that can be picked up and dropped
          as temporary measurement against bad performance or dropping things
          (this lead to long freezes and triggered the watchdog).
        - improved the performance of the drop command a bit.
        - switch from Event to EV for higher performance, easier usage,
          less bugs...
        - updated to release version of the gnu affero license.

2.31 Sun Nov 11 17:26:28 CET 2007
        - more thoroughly rename the binaries, contact addresses.
        - update the copyrights.
        - avoid backtraces due to old spells on some maps, sometimes causing
          crashes.
        - fix a problem where facedata wasn't initialised to zero properly,
          potentially causing crashes.
        - assign weapons on user load time, not login-time, avoiding
          crashes.

2.3  Sat Oct 27 11:22:38 CEST 2007
        - fixed an important bug that caused passwords to be forgotten.
        - implement *tag destinations for goto, slaying etc. and use it
          in some of the maps.
        - bigworldised many maps (islands as in pupland and aldwulf),
          which is now trivial to do.
        - removed all traces of the old (and never working) plug-in interface
          (70kb code less on amd64).
        - improve/tune scheduling priorities.
        - fix some freezing bugs.
        - fix a memory corruption problem in dynbuf.printf.
        - use channels for chat and many informational commands.
        - improved the tutorial.
        - create missile is now fixed.
        - race fields must now contain archetypes.
        - jumping skill now works as advertised.

2.2  Tue Sep 11 15:41:24 CEST 2007
        - relicense under the gnu affero license.
        - new inscription skill, can only inscribe INSCRIBABLE items.
        - implement server-side framework for generic resources.
        - use resource framework for server-provided ambient
          music.
        - save object owners (players only atm).
        - replace limited sound api with server-provided sound effects.
        - new sc (sound control) protocol command.
        - improve fxix protocol to include types.
        - exactly fill tcp segments, if possible.
        - output-rate is now an upper limit, the server will automatically
          (and quite perfectly) adjust to the network conditions, ensuring
          low latency even during bulk transfers (music, images, sounds etc.).
        - implement server-side widgets (i.e. client widgets controlled
          in the server side). this will allow future expansion without
          having to upgrade clients.
        - implement a (artwork) world map with realtime player position
          tracking.
        - new and more efficient extcmd (server still supports old extcmd
          protocol).
        - fixed lots of underflow/overflow bugs in diseases and general stats
          calcluation that could be easily exploited by users.
        - rebalanced diseases to spread more naturally/evenly.
        - completely asynchronous map loading even for tiled maps.
        - replace simple messaging protocol with channels carrying metadata
          (similar to message types, but more directed at the user).
        - reduce command processing latency by a whopping 120ms by
          reordering some processing steps inside the server. this directly
          reduces lag by 120ms.
        - actually send spell faces to the client.
        - implement player genders.
        - unclean logout/login results in: nothing if map hasn't reset,
          otherwise return to savebed and possible kill if the log-out
          was for too long.
        - fast socket-dead detection (kick player after 8 seconds without ack).
        - greatly reduce the cpu time needed to draw maps _again_.
        - archetypes are now subclasses of objects.
        - rebalanced shop greed and approval functions to be more realistic
          (and likely match the actual intention).
        - implement "crossfire pod" format for messages, with working bold,
          italic, gender-specific text, paragraphs etc.
        - implemented hint framework, players can opt to receive hints.
        - implemented (long) book framework, added some books from the cf wiki.
        - implement generic message framework that uses xml, utf8 for the client
          protocol and is capable of transmitting generic meta information.
        - implement (in a suboptimal way) per-player instantiated maps.
        - replace the nexus by a per-player tutorial map that teaches stuff
          better than the newbie house.
        - fix the magicmap colours.
        - optimise map update even more by removing unneeded code and checks.
        - decouple map and stats update from pl->ob and use pl->observe instead.
        - implement observe command.
        - major speed up in map refresh by replacing most get_map_from_coord
          calls with a simple comparison.
        - fix a latent crossfire bug that could crash the server because the
          map refresh did not update the mapspace.
        - support custom keys for regions and maps, regions are now
          refcount-managed.
        - allow worldmap overlays anywhere in the 000..999 range.
        - new system to acquire time slices for background jobs, to reduce
          jitter.
        - semi-persistent object-referencing framework (currently only players
          supported).
        - dependency tracking for perl extensions.
        - new slag-ex extension for cleaning cauldrons.
        - fix invoke result processing.
        - there are even less i/o syncpoints in the server now.
        - added map-tags extension that scans all maps for object tags
          and records them in the database (not used yet).
        - metaserver 2 support.
        - many more bugfixes and minor optimisations.

2.1  Sun May 27 04:21:29 CEST 2007
        - optimised event invocation (non-wanted events can now be
          skipped with 4-5 inlined instructions).
        - complete rewrite of town_portal: it now creates a portal
          to the "nearest" town only, travel is only possible
          to the town and back, anybody can use it (also removes
          one of the remaining syncpoints in the server).
        - complete rewrite of the range/attack skill slot system:
          there are now two slots, one for combat, one for ranged
          attacks.
        - introduce the concept of a current weapon (either a ranged
          or a combat weapon/skill/tool) and switch between them as
          needed.
        - rewrite bow code so bows get more useful: apply damage,
          attacktype and other stats to the arrows and treat
          bows as weapons. also rebalance the missile weapons skill
          so its damage increases with level.
        - rewrite the complete player speed logic: weapon_speed now
          works as documented and there are no unnatural speed boosts.
        - implement a utility - cfutil - that simplifies arch and map
          installation, replacing the old collect scripts and
          simplying deployment by scaling and cutting faces as required.
        - simplify the map protocol extensively by taking advantage
          of missing bigfaces, speeding up map generation immensely.
        - implement inherit keyword allowing archetypes to inherit from
          other archetypes.
        - rationalise archetype, region and treasurelist file format
          into a single file format and make them reloadable asynchronously.
        - make the worldmap, facedata (smoothing, faces, magicmap)
          reloadable at runtime.
        - implement 64x64 faceset support.
        - implement fxixsx protocol that saves
          a lot of bandwidth over the old image/face/smooth packets
          and allows images > packetsize, incremental and background
          transfers.
        - implement a bandwidth-saving smoothing protocol that works
          on a face basis as opposed to a mapspace basis.
        - the server can now rate-limit image uploads to not exceed
          a certain (client-configurable) speed while guarenteeing full
          freedom of movement.
        - implement new ex command to request item descriptions.
        - implement new msg command for in-game messages with meta
          information (using xml).
        - enforce utf-8 for all text messages.
        - added micropather (not used yet).
        - many, many bugfixes.

2.0  Tue Mar  6 15:22:53 CET 2007
        - make coroapi accessible to cf+.
        - moved map handling logic completely to perl
        - per player maps are now marked in the map
        - maps are saved completely differently now,
          and much more often.
        - rewrote map header parser and writer, to be much faster.
        - maps and players are now (in the average case) loaded
          and saved completely asynchronously, I/O contention will no
          longer freeze the server.
        - players and maps can be loaded anytime, without the player
          being logged in.
        - automatically generate method interfaces for perl from headers
        - unbundled freezethaw
        - mostly rewrote common/map.C
        - completely rewrite server/swap.C
        - introduced "runtime", the CCT clock (corrected crossfire time) :)
        - introduced new keyword for map files: file_format_version (integer, server version: 0)
        - better message for apply failures due to applymode
        - removed most all of the weather code
        - unified logging to stderr and file
        - too many minor changes to document

96			it has reset, which is better than putting it on the savebed, also as
97			proof that the palyer didn't use a savebed).

123	root	1.42	2.32 Sun Dec 2 18:11:01 CET 2007
124	elmex	1.41	- limited the number of items that can be picked up and dropped
125	root	1.42	as temporary measurement against bad performance or dropping things
126			(this lead to long freezes and triggered the watchdog).

143	root	1.32	- fixed an important bug that caused passwords to be forgotten.
144	root	1.31	- implement *tag destinations for goto, slaying etc. and use it
145			in some of the maps.

147			which is now trivial to do.
148	root	1.33	- removed all traces of the old (and never working) plug-in interface

167			- new sc (sound control) protocol command.
168			- improve fxix protocol to include types.
169			- exactly fill tcp segments, if possible.
170			- output-rate is now an upper limit, the server will automatically
171			(and quite perfectly) adjust to the network conditions, ensuring
172			low latency even during bulk transfers (music, images, sounds etc.).
173			- implement server-side widgets (i.e. client widgets controlled
174			in the server side). this will allow future expansion without
175			having to upgrade clients.
176			- implement a (artwork) world map with realtime player position
177			tracking.
178			- new and more efficient extcmd (server still supports old extcmd
179			protocol).

181			calcluation that could be easily exploited by users.
182			- rebalanced diseases to spread more naturally/evenly.
183			- completely asynchronous map loading even for tiled maps.
184	root	1.24	- replace simple messaging protocol with channels carrying metadata
185			(similar to message types, but more directed at the user).
186			- reduce command processing latency by a whopping 120ms by
187			reordering some processing steps inside the server. this directly
188			reduces lag by 120ms.
189			- actually send spell faces to the client.
190	root	1.23	- implement player genders.
191	root	1.24	- unclean logout/login results in: nothing if map hasn't reset,
192			otherwise return to savebed and possible kill if the log-out
193			was for too long.
194			- fast socket-dead detection (kick player after 8 seconds without ack).
195			- greatly reduce the cpu time needed to draw maps _again_.
196			- archetypes are now subclasses of objects.
197			- rebalanced shop greed and approval functions to be more realistic
198			(and likely match the actual intention).
199	root	1.23	- implement "crossfire pod" format for messages, with working bold,
200			italic, gender-specific text, paragraphs etc.
201	root	1.24	- implemented hint framework, players can opt to receive hints.
202			- implemented (long) book framework, added some books from the cf wiki.
203	root	1.23	- implement generic message framework that uses xml, utf8 for the client
204			protocol and is capable of transmitting generic meta information.
205	root	1.21	- implement (in a suboptimal way) per-player instantiated maps.
206			- replace the nexus by a per-player tutorial map that teaches stuff
207			better than the newbie house.

210			- decouple map and stats update from pl->ob and use pl->observe instead.
211			- implement observe command.
212	root	1.20	- major speed up in map refresh by replacing most get_map_from_coord
213			calls with a simple comparison.
214			- fix a latent crossfire bug that could crash the server because the
215			map refresh did not update the mapspace.
216	root	1.24	- support custom keys for regions and maps, regions are now
217			refcount-managed.
218			- allow worldmap overlays anywhere in the 000..999 range.
219			- new system to acquire time slices for background jobs, to reduce
220			jitter.
221	root	1.27	- semi-persistent object-referencing framework (currently only players
222			supported).
223	root	1.22	- dependency tracking for perl extensions.
224	root	1.24	- new slag-ex extension for cleaning cauldrons.
225			- fix invoke result processing.
226			- there are even less i/o syncpoints in the server now.

228			and records them in the database (not used yet).
229	root	1.28	- metaserver 2 support.
230	root	1.22	- many more bugfixes and minor optimisations.
231	root	1.16
232	root	1.15	2.1 Sun May 27 04:21:29 CEST 2007
233	root	1.14	- optimised event invocation (non-wanted events can now be
234			skipped with 4-5 inlined instructions).
235	root	1.12	- complete rewrite of town_portal: it now creates a portal
236			to the "nearest" town only, travel is only possible
237	root	1.13	to the town and back, anybody can use it (also removes
238			one of the remaining syncpoints in the server).
239	root	1.10	- complete rewrite of the range/attack skill slot system:
240			there are now two slots, one for combat, one for ranged
241			attacks.
242			- introduce the concept of a current weapon (either a ranged
243			or a combat weapon/skill/tool) and switch between them as
244			needed.
245			- rewrite bow code so bows get more useful: apply damage,
246			attacktype and other stats to the arrows and treat
247			bows as weapons. also rebalance the missile weapons skill
248			so its damage increases with level.
249			- rewrite the complete player speed logic: weapon_speed now
250			works as documented and there are no unnatural speed boosts.
251	root	1.6	- implement a utility - cfutil - that simplifies arch and map
252			installation, replacing the old collect scripts and
253	root	1.9	simplying deployment by scaling and cutting faces as required.
254			- simplify the map protocol extensively by taking advantage
255			of missing bigfaces, speeding up map generation immensely.
256	root	1.6	- implement inherit keyword allowing archetypes to inherit from
257			other archetypes.
258			- rationalise archetype, region and treasurelist file format
259			into a single file format and make them reloadable asynchronously.
260	root	1.9	- make the worldmap, facedata (smoothing, faces, magicmap)
261			reloadable at runtime.
262	root	1.6	- implement 64x64 faceset support.
263			- implement fxixsx protocol that saves
264			a lot of bandwidth over the old image/face/smooth packets
265	root	1.11	and allows images > packetsize, incremental and background
266			transfers.
267	root	1.6	- implement a bandwidth-saving smoothing protocol that works
268			on a face basis as opposed to a mapspace basis.
269	root	1.7	- the server can now rate-limit image uploads to not exceed
270			a certain (client-configurable) speed while guarenteeing full
271			freedom of movement.
272	root	1.8	- implement new ex command to request item descriptions.
273			- implement new msg command for in-game messages with meta
274			information (using xml).
275	root	1.9	- enforce utf-8 for all text messages.
276	root	1.13	- added micropather (not used yet).
277	root	1.6	- many, many bugfixes.

279	root	1.5	2.0 Tue Mar 6 15:22:53 CET 2007
280	root	1.1	- make coroapi accessible to cf+.
281			- moved map handling logic completely to perl
282			- per player maps are now marked in the map
283	root	1.2	- maps are saved completely differently now,
284			and much more often.
285	root	1.17	- rewrote map header parser and writer, to be much faster.
286	pippijn	1.4	- maps and players are now (in the average case) loaded
287	root	1.2	and saved completely asynchronously, I/O contention will no
288			longer freeze the server.
289	pippijn	1.4	- players and maps can be loaded anytime, without the player
290	root	1.2	being logged in.
291	root	1.1	- automatically generate method interfaces for perl from headers
292			- unbundled freezethaw
293			- mostly rewrote common/map.C
294			- completely rewrite server/swap.C
295			- introduced "runtime", the CCT clock (corrected crossfire time) :)
296			- introduced new keyword for map files: file_format_version (integer, server version: 0)
297			- better message for apply failures due to applymode
298			- removed most all of the weather code
299			- unified logging to stderr and file
300			- too many minor changes to document
