cadmus character showing lots of russian text
Hiya,
I am testing out the docker image for local development, and when I log in cadmus, which is supposed to be an english character, I still get lots of russian text. Am I confused about how this works? If there's no way to turn off russian text, is there a way to make an english only version? I ask because I'm considering using dreamland for a base for a mud I'm working on, but I know nothing about russian so having russian text to translate would be a pain.
Thanks!
-Michael.
Change internal encoding from koi8-r to utf-8
TODO
- Make sure all formatted output is done via 1-2 common functions (e.g. Character.printf and pecho)
- Rework printf to support utf-8

MUD tags such as {hl are not stripped, i.e.
{hlhttps://google.com{x should become https://google.com, instead it becomes lhttps://google.com -
Single asterix and underscore interfere with Markdown syntax, causing error 400 "Bad Request: can't parse entities: Can't find end of the entity starting at byte offset ...".

Fenia api: some fields are duplicated on the web
For 'Structures API' on https://dreamland.rocks/feniaapi.html, the table for read/write fields looks like this:
bitvector | какие биты добавятся полю, указанному в where
bitvector | какие биты добавятся полю, указанному в where
duration | длительность, -1 для вечных аффектов
duration | длительность, -1 для вечных аффектов
For 'Character API', read-write fields are listed first as "ro", then as "rw".

Get rid of "player memory" abstraction
No need to keep only a subset of player info in memory anymore, can keep all profile fields. PCharacterManager will hold a map of offline and online PCharacters, classes such as PCMemoryInterface and PCharacterMemory will become obsolete.
As additional bonus, consider keeping all player items (inv, eq) in memory, introducing a concept of "offline object".

Fenia core grows too big, lock table out of entries
Two issues combined here.
- FeniaSpellContext objects were never destroyed. Each casted spell resulted in new object in the fenia db. Number of objects in the fenia database grew up to 180k pretty fast. This leak was fixed in 66f7c51
- Initial number of BDB lock entries is too small to load 180k records, resulting in this error during DL startup:
[Mar 04 02:31:58]:N: Loading DbContext: fenia:objects...
BDB2055 Lock table is out of available lock entries
[Mar 04 02:32:06]:E: Dbc::get: Cannot allocate memory:
[Mar 04 02:32:06]:N: Total 175695 records loaded
Lock table size can be increased by calling DbEnv::set_lk_max_locks method, see this discussion for reference.
DL fails to start under WSL due to invalid fenia core format
Need to provide fenia core in dump format, and run db_restore as part of the configuration.
Поддержка IDE и сборка под Windows
Исторически собирался под mingw компилятор. Нужно попытаться восстановить хотя бы старую сборку.
По поводу IDE - сейчас он как-то работает с эклипсом для С++, с включенным плагином CDT. Возможно, есть лучшие варианты IDE для проектов с autotools.

Добрый день!
Предельно извиняюсь, что пишу сюда, но увидел Руффину в администраторах мадконнектора. Надеюсь, не ошибся. Там проблема: я не могу войти, так как мне пишется, что "Вы превысили максимально допустимое количество попыток входа.

This trace shows that the mob had 4 affects left: 2 inspire affects, prot evil and sanctuary, and the one being removed in this update call was "charm person" affect. Its removal handler called follower_stop() which in turn called affect_strip(gsn_charm_person) thus calling double deallocate for the same pointer.

A null pObjIndex is passed to create_item_for_mob function. Likely cause: in the limited set of areas shipped for local dev, an item vnum is missing but is configured to be reset somewhere. Let's see what are room, obj and mob vnums:
gdb) set print pretty
(gdb) set print static no
(gdb) p mob->pIndexData->vnum
$5 = 5311
gdb) p mob->in_room->vnum
$6 = 5317
(gdb) p pReset->arg1
$8 = 601
Item 601 belongs to ofcol2.are which is not included in area.local package. To fix this crash, need to check for null obj index before calling create_item_for_mob function.
