Added class EQEmu::Random
Functions:
EQEmu::Random::Int(int low, int high)
EQEmu::Random::Real(double low, double high)
EQEmu::Random::Roll(int required)
EQEmu::Random::Roll(double required)
EQEmu::Random::Reseed()
For zone, you will access the random object through the zone object
ex.
zone->random.Int(0, 100);
Int returns a random int between low and high
Real returns a random double between low and high
Roll(int) returns true if Int(0, 99) < required is true
Roll(double) returns true if Real(0.0, 1.0) <= required is true
Created database revision define, this is located in version.h in common #define CURRENT_BINARY_DATABASE_VERSION 9057
- This revision define will need to be incremented each time a database update is made
- Along with a revision define increment, you will need to update the db_update manifest located in:
- https://raw.githubusercontent.com/EQEmu/Server/master/utils/sql/db_update_manifest.txt
- An entry needs to be made at the bottom of the manifest, the entry is quite simple
- Example: 9057|2014_11_13_spells_new_updates.sql|SHOW COLUMNS FROM `spells_new` LIKE 'disallow_sit'|empty|
- This latest example is checking to see if the spells_new table contains the column 'disallow_sit', if its empty, the update needs to be ran
- More examples of match types below:
# Example: Version|Filename.sql|Query_to_Check_Condition_For_Needed_Update|match type|text to match
# 0 = Database Version
# 1 = Filename.sql
# 2 = Query_to_Check_Condition_For_Needed_Update
# 3 = Match Type - If condition from match type to Value 4 is true, update will flag for needing to be ran
# contains = If query results contains text from 4th value
# match = If query results matches text from 4th value
# missing = If query result is missing text from 4th value
# empty = If the query results in no results
# not_empty = If the query is not empty
# 4 = Text to match
- The manifest contains all database updates 'Required' to be made to the schema, and it will contain a working backport all the way back to SVN -
currently it is tested and backported through the beginning of our Github repo
- On world bootup or standalone run of db_update.pl, users will be prompted with a simple menu that we will expand upon later:

EQEmu: Automatic Database Upgrade Check
============================================================
Operating System is: MSWin32
(Windows) MySQL is in system path
Path = C:\Program Files\MariaDB 10.0\bin/mysql
============================================================
Binary Database Version: (9057)
Local Database Version: (9057)
Database up to Date: Continuing World Bootup...

Database Management Menu (Please Select):
1) Backup Database - (Saves to Backups folder)
Ideal to perform before performing updates
2) Backup Database Compressed - (Saves to Backups folder)

3) Check for pending Database updates

Created db_update.pl, placed in utils/scripts folder, used for the automatic database update routine (Linux/Windows)
- db_update.pl script created db_version table if not created, if old one is present it will remove it
Created db_dumper.pl, placed in utils/scripts folder, used for the automatic database update routine backups and standalone backups (Linux/Windows)
World will now check the db_update.pl script on bootup, if the db_update.pl script is not present, it will fetch it remotely before running -
when db_update.pl is done running, world will continue with bootup
world.exe db_version - will report database binary version
Currently working: stat bonuses and client side only effects
Currently not working: Mark NPC and others that need more server side work
Currently only tested on UF, Ti and 62 may work, but not tested
SoF, SoD, and RoF need packet translators, which are most likely the same as UF
- Need to convert a list of functions and columns and should be ready to start intensive testing phase
- All preliminary tests show things working great
- All of player profile is saved and loaded from the database
- DBAsync has been completely removed from all code
- Removed zone/dbasync.cpp/.h
- Removed common/dbasync.cpp/.h
- Removed dbasync from cmake commmon and zone
- Cleaned up a ton of functions
- Added several tables to world CheckDatabaseConversions script:
- `character_skills`
- `character_languages`
- `character_bind`
- `character_alternate_abilities`
- `character_currency`
- `character_data`
- `character_spells`
- `character_memmed_spells`
- `character_disciplines`
- `character_material`
- `character_tribute`
- `character_bandolier`
- `character_potionbelt`
- Character select now loads from `character_data`
- Character creation now creates to `character_data`
- Updated function Database::UpdateName to use `character_data`
- Updated function Database::CheckUsedName to use `character_data`
- Updated function Database::MoveCharacterToZone to use `character_data`
- Updated function Database::SetLoginFlags to use `character_data`
- Updated function Database::SetFirstLogon to use `character_data`
- Updated function Database::SetLFG to use `character_data`
- Removed CopyCharacter functions and commands, to be recreated later since it never worked to begin with
- Removed SharedDatabase::SetPlayerProfile
- Trimmed down redundant case switch statements for World sendpackets to QueryServ
- Added Character Methods to Database class:
Loads:
bool LoadCharacterBandolier(uint32 character_id, PlayerProfile_Struct* pp);
bool LoadCharacterTribute(uint32 character_id, PlayerProfile_Struct* pp);
bool LoadCharacterPotions(uint32 character_id, PlayerProfile_Struct* pp);
Saves:
bool SaveCharacterBindPoint(uint32 character_id, uint32 zone_id, uint32 instance_id, float x, float y, float z, float heading, uint8 is_home);
bool SaveCharacterCurrency(uint32 character_id, PlayerProfile_Struct* pp);
bool SaveCharacterData(uint32 character_id, uint32 account_id, PlayerProfile_Struct* pp);
bool SaveCharacterAA(uint32 character_id, uint32 aa_id, uint32 current_level);
bool SaveCharacterSpellSwap(uint32 character_id, uint32 spell_id, uint32 from_slot, uint32 to_slot);
bool SaveCharacterSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
bool SaveCharacterMemorizedSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
bool SaveCharacterMaterialColor(uint32 character_id, uint32 slot_id, uint32 color);
bool SaveCharacterSkill(uint32 character_id, uint32 skill_id, uint32 value);
bool SaveCharacterLanguage(uint32 character_id, uint32 lang_id, uint32 value);
bool SaveCharacterDisc(uint32 character_id, uint32 slot_id, uint32 disc_id);
bool SaveCharacterTribute(uint32 character_id, PlayerProfile_Struct* pp);
bool SaveCharacterBandolier(uint32 character_id, uint8 bandolier_id, uint8 bandolier_slot, uint32 item_id, uint32 icon, const char* bandolier_name);
bool SaveCharacterPotionBelt(uint32 character_id, uint8 potion_id, uint32 item_id, uint32 icon);
Deletes:
bool DeleteCharacterSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
bool DeleteCharacterMemorizedSpell(uint32 character_id, uint32 spell_id, uint32 slot_id);
bool DeleteCharacterDisc(uint32 character_id, uint32 slot_id);
bool DeleteCharacterBandolier(uint32 character_id, uint32 band_id);
Basic character data, currency and AA are being loaded/saved from the database, currently working on the rest right now.
- Character blob removed from load for testing. Lots of cleanup yet to be done so don't judge code yet.
Saves:
- Two FULL saves when looting a corpse, this has been reduced to just currency saves on initial loot and trimmed to one save since AddToMoneyPP did it already
- Every time a player moves coin with any situation (Splits/Trades/Merchant/Skills/Bank Coin Exchange/Coin Moves), a full save is made, this is now just a currency save
- Every time a player skilled up at a skill vendor, a full blob save hit was made, this is not just a currency hit
see that the query 'SELECT varname, value, unix_timestamp() FROM variables where unix_timestamp(ts) >= timestamp' is called every 10 seconds. This function is loading
variables that are initially loaded on World and Zone bootup. When running a large amount of zone servers, the amount of MySQL chatter that is produced is enormous and
unnecessary. For example, if I ran 400 zone servers, I would see 3,456,000 unnecessary queries from all idle or active zone processes in a 24 hour interval.
