Metin2 chat category filters with reviewed preferences and lifecycle
For administrators and client developers maintaining a legacy Python 2.7 Metin2 fork. This is Owsap's owner-supplied Chatting Window Renewal (Mini Version): a revised chat bar and settings for General, Group, Guild, Shout, System, Message, Dice, EXP, Items and Currency. It is an integration kit, not serverfiles or a complete client. Extra tab/language labels in the original locale do not mean those features are implemented.
M2City r1 fixes
The original loads local preferences through pickle, sets a successful-load flag before validation, leaves file handles open and mixes unsaved settings with active filters. The revised helper reads only a bounded 18-byte format containing ten booleans; it never imports or reads legacy pickle data. Paths are derived from a hash of a configured server ID and character name, preventing names from becoming arbitrary file paths. No password is stored.
Save commits only on success and reports a write failure without closing or applying the draft. Cancel/close restore the saved settings. Confirmed Reset changes the draft and still requires Save. A character change cannot save another character's draft. One previous generation supports recovery after interrupted replacement; this does not claim crash-atomic or concurrent-process storage.
The added EXP/Item/Money types are now disabled when the chat log switches from Info to another category. The original only enabled them, allowing unwanted system lines to remain in other views. A duplicated native search context incorrectly used item2 where the replacement used item; that context now matches the correct item branch while preserving the original locale bytes.
Settings use weak owner/callback references. Teardown closes the outstanding confirmation, releases widgets and dictionaries, and detaches the parent. Repeated Reset clicks no longer create competing dialogs. The normal ChatWindow owner still controls lifetime; this package does not create another global chat singleton.
Artwork and installation
All 25 supplied SUB definitions were checked. The common atlas is supplied one directory above the SUB files; references now use its explicit pack path. Bottom buttons previously referenced an absent Windows.dds. They now use blank chat-tab images already supplied, with checked English labels and matching positions. The checkbox uses the supplied checked texture. Border filename case and expanded-image repeat values are corrected. The preview is an offline layout composition, not an in-game screenshot.
Read INSTALL.txt. Extract the original to staging, overlay reviewed/, then merge the instruction fragments into your own existing files. Do not replace complete native/root files with tutorial fragments or apply both versions. Add m2chat_options.py, set a unique SERVER_KEY, install the lowercase uiscript path and merge locales. Preserve standard base UI APIs and normal chat phase teardown. Client and server chat enums/flags must match; compile both sides and reconcile existing custom message IDs. Longer translated button labels need a layout check.
Validation and boundaries
17 source/text files reviewed, 25 SUB configs inspected, 28 images decoded. Eight isolated Python 3 test groups passed, including all 1024 preference combinations, malformed files, interrupted-save recovery, draft/save/cancel/reset behavior, character changes, category transitions and 100 create/open/reset/destroy cycles. Four-resolution bounds/assets checks and legacy grammar parses passed. Test source and results are included.
No full Metin2 client/server compilation, actual Python 2 engine run, live packet flow or GPU rendering was performed. Before shipping, test flags on/off, all real chat categories, reconnect, write failures and translations in your actual staging client. No database migration or server economy change is part of this kit.
