Надо просто по дефолту ставить реализацию, которая содержит else блоки. Тогда не надо будет эту писанину с if/else.

Это не моё изменение - код был до моего PR. Согласен что можно сделать default implementation для WorldDataSource, но это требует отдельного рефакторинга (создать NullDataSource или всегда иметь valid instance).

Add world checksum calculation for refactoring verification
ac39c6b 
Step 1 of world loading refactoring plan - baseline checksums.

New files:
- src/engine/db/world_checksum.h/cpp: CRC32-based checksum calculation
  for zones, rooms, mobs, objects, and triggers

Features:
- Calculates individual checksums per entity type using XOR aggregation
- Combined checksum for detecting any world data changes
- Detailed per-object checksums saved to file for diff analysis
- CLI flag -C to disable checksum calculation

Integration:
- Checksums calculated at end of GameLoader::BootWorld()
- Results logged to syslog and saved to checksums_detailed.txt

CMake additions:
- FULL_WORLD_PATH option for specifying full world data location
- Automatic setup of small/full data directories in build dir

Baseline checksums:
  Small World (lib):     Combined: 4E6499FF
  Full World:            Combined: BB58755C

Detailed checksums saved in checksums_small.txt and checksums_full.txt
for future comparison after refactoring.

Add IWorldDataSource abstraction for pluggable world loading
f5a3894 
Introduces an interface-based abstraction layer for world data loading:
- IWorldDataSource interface with LoadZones/Triggers/Rooms/Mobs/Objects
- LegacyWorldDataSource wraps existing BootIndex() calls
- GameLoader::BootWorld() now accepts optional data source parameter
- Excludes zone_rn from room checksums (runtime-calculated value)
- Fixes compiler warnings (unused variable, strncpy truncation)

Checksums verified identical before/after refactoring:
- Small world: B6DA5931
- Full world: 82CF7A3E

@kvirund @claude
Fix object loading to match Legacy loader behavior
9a70c6e 
- Clear runtime flags (kTransformed, kTicktimer) after loading objects
- Set max_in_world to -1 for objects with kZonedacay or kRepopDecay flags

This ensures SQLite loader produces identical object prototypes to Legacy.
All 5192 objects now match (100% checksum match).

- Add TrimRight for script lines to remove trailing whitespace
- Add indent_trigger call to normalize script indentation
- Include dg_olc.h for indent_trigger function

All world checksums now match between Legacy and SQLite loaders.

Co-Authored-By: Claude Opus 4.5 <[email protected]>
@kvirund @claude
Add index file support and checksum comparison tools
fbbfbe7 
- Add 'enabled' column to SQLite schema for zones, rooms, mobs, objects,
  triggers to support index file filtering
- Update converter to read index files and mark non-indexed entities
  as disabled (enabled=0)
- Update SQLite loader to filter on enabled=1, matching Legacy behavior
- Add minimum_remorts column to objects table
- Add detailed checksum comparison infrastructure:
  - SaveDetailedBuffers() saves serialization buffers per entity
  - LoadBaselineChecksums() loads baseline for comparison
  - CompareWithBaseline() reports mismatches with field-level detail
- Update compare_world_checksums.sh with --rebuild and --reconvert flags
- Fix room exit serialization to use vnum instead of rnum

Checksum verification: Small world shows 100% match between Legacy and
SQLite loaders (zones, rooms, mobs, objects, triggers all identical).

Fix encoding corruption and refactor BootWorld with IWorldDataSource
5599bbb 
- Restored KOI8-R encoding (was corrupted in 0c9ca3c)
- Added includes for world_checksum, legacy/sqlite data sources
- Renamed world_loader to game_loader
- Refactored BootWorld to use IWorldDataSource abstraction
- Added checksum calculation and baseline comparison at boot
- Added no_world_checksum flag to disable checksums

4b44db6 
- setup_test_dirs.sh: Creates test directories for Legacy/SQLite comparison
- run_load_tests.sh: Runs performance tests and compares checksums
- Add test/ and magic.mgc to .gitignore

Fix SQLite trigger loader: use rnum instead of vnum in constructor
c669fd4 
The Trigger constructor expects rnum (runtime array index) as the first
parameter, not vnum (persistent database ID). Passing vnum caused
out-of-bounds array access in GET_TRIG_VNUM macro when the vnum was
larger than the trig_index array size, resulting in segfaults during
zone reset on larger worlds.

@kvirund @claude
Fix converter to match Legacy loader string handling
5a8964c 
- Filter files by pattern ^\d+\.<ext>$ to ignore backup files like 16.old.obj
- Fix armor parsing for negative values (use lstrip('-').isdigit())
- Use \r\n for joining multi-line aliases and case names (Legacy fread_string
  converts \n to \r\n)
- Remove .strip() calls that were removing control characters like \x1d
- Keep trailing spaces in aliases to match Legacy behavior

This significantly reduces checksum differences:
- MOB: 1354 → 1
- OBJ: still has differences (to be investigated)

Fix object flag loading and duplicate trigger support
ce0954c 
Schema changes:
- Replace UNIQUE constraint on entity_triggers with trigger_order column
- Allows duplicate triggers (same trigger attached multiple times)

Converter changes:
- Add trigger_order field for proper trigger ordering
- Fix plane 2 offset in parse_ascii_flags (43 → 60)
- Each plane has 30 bits, not varying sizes

Loader changes:
- Add explicit flag maps for affect, anti, no flags
- Replace ITEM_BY_NAME with direct map lookups
- More reliable flag loading without silent failures

Progress (small world after reconvert):
  Zones:    100.0% (0 diff)
  Rooms:     99.9% (3 diff - missing kNoItem plane 2 flag)
  Mobs:     100.0% (0 diff)

Revert CMake copy changes - caused build errors
ea7329d 
The copy_directory approach caused errors during CMake configuration.
Reverting to working symlink-based approach.

Will use run_load_tests.sh cleanup instead for fresh worlds.

Fix world setup: use copies and in-place conversion
80070cf 
CMakeLists.txt:
- Replace symlinks with copies for small world setup
- Copy lib/ first, then overlay lib.template/ with --update=none
- Remove and recreate small/ directory on each CMake run

tools/run_load_tests.sh:
- Convert worlds IN-PLACE: -i $dest_dir -o $dest_dir --delete-source
- Remove checks for symlinks (cfg is now a copy, not symlink)
- Check for world.db (SQLite) and world/dictionaries (YAML) instead
- Apply same logic to both small and full worlds

This fixes the issue where:
1. Symlinks pointed to shared lib.template/world (not isolated)
2. Converter wrote to lib.template instead of build directory
3. Multiple test runs interfered with each other

Now each loader gets its own isolated world copy that is
converted in-place and cleaned up properly.

Remove converted YAML files from lib.template
c5519fc 
These files were accidentally committed in 96dfda7 when converter
wrote through symlinks to lib.template/world/.

lib.template should only contain Legacy world format (mob/, obj/,
wld/, zon/, trg/) - not converted YAML or SQLite data.

Removed:
- lib.template/world/world/ (YAML world)
- lib.template/world/mobs/, objects/, triggers/, zones/ (YAML dirs)
- lib.template/world/dictionaries/ (YAML dictionaries)

Fix setup_small_world: remove symlink creation code
6e331a1 
Removed obsolete code that created symlinks for text/misc/cfg

Fix YAML loader checksums to match Legacy loader (100%)
0998176 
Achievements:
- Zones:    7C788E1F ✅ (100% match)
- Rooms:    8C0277A7 ✅ (100% match)
- Mobs:     CEBB697B ✅ (100% match)
- Objects:  7E2C7CC8 ✅ (100% match)
- Triggers: 91924F29 ✅ (100% match)

Critical fixes:
1. Add vnum sorting for triggers before merge (yaml_world_data_source.cpp:710-723)
   - GetTriggerRnum uses binary search which requires sorted trig_index
   - Previously triggers were added in random order from parallel threads
   - Now: collect all triggers, sort by vnum, then add to trig_index

2. Fix room trigger validation (yaml_world_data_source.cpp:908-927, 1019-1030)
   - Previously: room triggers added directly without existence check
   - Issue: non-existent triggers (e.g., trigger 1170 for room 136) were added to checksums
   - Now: store triggers temporarily, attach via AttachTriggerToRoom with validation
   - Result: only existing triggers are added to room->proto_script

3. Optimize parallel loading: remove mutexes, use thread-local storage
   - Objects: replaced mutex+object_triggers with thread_triggers vector (yaml_world_data_source.cpp:1768-1774)
   - Rooms: added triggers field to ParsedRoomBatch (yaml_world_data_source.h:39)
   - Benefits: faster (no contention), simpler (no deadlock risk), safer

Technical details:
- Binary search in GetTriggerRnum/GetMobRnum/GetObjRnum/GetRoomRnum requires sorted arrays
- Thread-local maps merged in sequential phase via std::map::insert
- Trigger attachment uses base class methods with proper validation

Test results (small world):
- Legacy vs YAML: MATCH (all 5 checksums identical)
- No SYSERR for non-existent triggers in valid cases
- Parallel loading maintains deterministic order via vnum sorting

Add comprehensive performance testing report
3ab1c76 
Performance results:
- Small world: All loaders ~2s (negligible difference)
- Full world: SQLite 27.7s (fastest), Legacy 30.3s, YAML 40.5s
- YAML 34% slower on full world due to parsing overhead

Thread scaling results:
- Small world: 1.12-1.18x speedup with 4-8 threads
- Full world: Minimal speedup (<1%) - needs investigation

Note: Thread scaling on full world significantly worse than expected.
Previous benchmarks showed 3.5x speedup with 8 threads, current shows ~1.0x.
Threading implementation may be degraded - requires investigation.

Test coverage:
✅ All checksums match (100%) across all loaders, worlds, build types
✅ Debug build with ASAN - no errors
✅ Thread safety verified (identical checksums across 1/2/4/8 threads)
✅ Performance benchmarks for small and full worlds

Fix YAML_THREADS environment variable not being read
c041c36 
The YAML loader was ignoring the YAML_THREADS environment variable because
RuntimeConfiguration::m_yaml_threads was never initialized and the
load_world_loader_configuration() function was not implemented.

Changes:
- Added load_world_loader_configuration() function to read YAML_THREADS env var
- Initialize m_yaml_threads to 0 in RuntimeConfiguration constructor
- Call load_world_loader_configuration() during config file loading
- YAML_THREADS env var takes precedence over XML configuration
- Fallback to XML <world_loader><yaml><threads> if env var not set
- Sanity check: thread count must be between 1 and 64

Performance results (full world, Release build):
- YAML_THREADS=1: 52.762s (baseline)
- YAML_THREADS=2: 32.466s (1.62x speedup)
- YAML_THREADS=4: 22.654s (2.33x speedup)
- YAML_THREADS=8: 18.196s (2.90x speedup)

Thread scaling is now working correctly. The YAML loader properly respects
the YAML_THREADS environment variable for controlling parallel loading.

Fix configuration file path and improve error reporting
eebb214 
Changed configuration file path from lib/misc/configuration.xml to
misc/configuration.xml to match actual directory structure.

Changes:
- RuntimeConfiguration::CONFIGURATION_FILE_NAME: "lib/misc/..." -> "misc/..."
- Added explicit ERROR/WARNING messages when config file fails to load
- Clarified that YAML_THREADS will fallback to hardware_concurrency()
- Updated test report to remove old incorrect thread scaling data

Before: Configuration file expected at <data_dir>/lib/misc/configuration.xml
After:  Configuration file expected at <data_dir>/misc/configuration.xml

This matches the actual structure created by lib.template and avoids
needing to copy files to non-standard locations during testing.

Error reporting improvement:
- Silent failure replaced with clear ERROR/WARNING to stderr
- Users now see why YAML_THREADS might be ignored (missing config)
- Helps diagnose configuration issues before syslog initialization

Fix loader comparison: YAML with 8 threads is 40% faster than Legacy
07c584d 
Updated loader performance comparison with correct YAML_THREADS=8 data.
Previous report incorrectly showed YAML as slowest (40.5s, 34% slower).
Actual data shows YAML with 8 threads is FASTEST (18.2s, 40% faster)!

Corrected performance ranking:
1. YAML (8 threads): 18.196s - FASTEST, 40% faster than Legacy
2. SQLite:          27.715s - 9% faster than Legacy
3. Legacy:          30.254s - Baseline
4. YAML (1 thread): 52.762s - Not recommended

Key insight: Multi-threading is CRITICAL for YAML performance.
Production recommendation changed: Use YAML with YAML_THREADS=8 for
best performance + human-readability.

Add room description content to checksums
a8b5285 
Include actual description text (not just index) in room checksums
to detect mismatches in description assignment between loaders.

This will help identify issues where different loaders assign
different descriptions to the same room (e.g., room 5000 getting
wrong description text in YAML loader vs Legacy loader).

Uses GlobalObjects::descriptions().get() to retrieve actual text
content, falling back to temp_description if set.

Problem: RoomDescriptions::merge() was passing 0-based loop index
to LocalDescriptionIndex::get() which expects 1-based indices.
This caused all room descriptions to be shifted by one position,
resulting in rooms displaying wrong descriptions.

Example: Room 5000 "Комнаты отдыха" was showing description from
room 4829 "На полянке" (about Misha and mosquitoes).

Fix: Convert loop index from 0-based to 1-based when calling get():
  local_index.get(local_idx + 1)

Both LocalDescriptionIndex and RoomDescriptions use 1-based indexing
where 0 means "no description", matching Legacy loader behavior.

Remove accidentally added board files from lib.template
2969b42 
These files were added by mistake in commit 96dfda7.
Board files should not be in lib.template as they are
created automatically during server initialization.

Refactor trigger indenter: replace global state with TriggerIndenter …
5418f25 
…class

Problem: dirty_indent_trigger() used thread_local static stack,
making state management implicit and hard to test.

Solution: Created TriggerIndenter class that encapsulates indentation
state and logic. Removes dependency on global/thread_local storage.

Changes:
- New files: trigger_indenter.h, trigger_indenter.cpp
- TriggerIndenter class with indent() method and private stack
- Updated indent_trigger() to use thread_local TriggerIndenter instance
- Kept dirty_indent_trigger() for now (unused, will be removed later)
- Fixed compiler warning in compact.trie.prefixes.cpp test

Benefits:
- Explicit state management (no hidden global state)
- Easier to test (can create indenter instances)
- Better encapsulation
- Maintains same API (indent_trigger unchanged)

Update .gitignore to exclude test data directories
3946721 
Add data/ and misc/ to .gitignore - these directories are created
by CMake during test builds (copied from lib.template).

Also remove obsolete YAML_THREAD_SCALING_REPORT.md (replaced by
YAML_CHECKSUM_TEST_REPORT.md).

Improve YAML converter: use block scalar format for multiline strings
1e76133 
Problem: Multiline descriptions in YAML were formatted with explicit \r\n
escape sequences, making them hard to read and edit:
  description: "Text line 1\r\nText line 2\r\n"

Solution: Use YAML literal block scalar (|) format for cleaner output:
  description: |
    Text line 1
    Text line 2

Changes:
- Import LiteralScalarString from ruamel.yaml.scalarstring
- Add to_literal_block() helper to wrap multiline strings
- Apply to all multiline fields:
  * Room descriptions, exit descriptions, extra descriptions
  * Mob short/long descriptions
  * Object short_desc, action_desc, extra descriptions
  * Trigger scripts
  * Zone metadata descriptions

Benefits:
- Much more readable YAML files
- Easier to edit descriptions manually
- Preserves exact formatting (newlines)
- Standard YAML practice for multiline text

Example output:
  description: |
    Хозяин устроил здесь комнаты для отдыха. Любой желающий может
    остановиться здесь и передохнуть после дальней дороги...

Fix KOI8-R encoding corruption in dg_db_scripts.cpp
53e1964 
Restore correct UTF-8 Russian encoding in comments while preserving
TriggerIndenter refactoring changes (include and class usage).

Previous commit had corrupted encoding (О©╫О©╫ characters), restored
from clean version before corruption.

Fix to_literal_block: check for actual CR+LF bytes, not literal string
764ee51 
Problem: to_literal_block() was checking for literal string '\\r\\n' (4 chars)
instead of actual CR+LF bytes '\r\n' (2 bytes).

Result: Multiline descriptions were still output with quoted \r\n escapes
instead of YAML | block format.

Fix: Change check from '\\\\r\\\\n' to '\r\n' to match actual bytes
from '\r\n'.join() operations in parser.

Test result:
  Before: description: "text\r\nmore\r\n"
  After:  description: |
            text
            more

Fix _convert_to_plain to handle LiteralScalarString for PyYAML
e80219e 
Problem: When using PyYAML (default), _convert_to_plain() didn't convert
LiteralScalarString objects to plain strings. This caused PyYAML to fall
back to pickling them with Python-specific tags like:
  !!python/object/new:ruamel.yaml.scalarstring.LiteralScalarString

This only affected objects with multiline descriptions containing \r\n
(like object 10700), which triggered to_literal_block() wrapper.

Fix: Add LiteralScalarString detection in _convert_to_plain() and convert
to plain string using str().

Result: All YAML files now use clean YAML syntax, no Python tags.

Switch converter to ruamel.yaml for proper literal block support
a8d87aa 
Problem: PyYAML doesn't support LiteralScalarString natively, so multiline
descriptions were output as quoted strings with \n escapes:
  description: "Line1\nLine2\n"

This is hard to read and may cause checksum differences.

Solution: Use ruamel.yaml (slower but ~3x, but better output quality):
  description: |
    Line1
    Line2

Result: Clean, readable YAML with literal blocks for multiline text.
Note: Kept _convert_to_plain() LiteralScalarString handling as fallback.

Update documentation: ruamel.yaml is now default
982118f 
Changed default from PyYAML to ruamel.yaml for better output quality:
- Literal blocks (|) for multiline text
- Comment support
- Proper YAML formatting

PyYAML remains available with --yaml-lib pyyaml for fast conversions
where output quality is not critical.

Fix argparse default: use ruamel.yaml by default
bf1a8ea 
Problem: Even though _yaml_library was set to 'ruamel', the argparse
default was still 'pyyaml', which overwrote the variable.

Fix: Changed argparse default to 'ruamel' to match the global default.

Now ruamel.yaml is truly the default for proper | block output.
