Version 3.4 of Snipe server core released

[system]

The largest release to date of Snipe server is now available for download from Github repository. This release brings the following additions and changes to the Snipe server platform:

New packages:

• 
  Room manager package. Used for creation and management of the player rooms on slave servers. Persistent rooms are supported.


• 
  Leaderboards package. Manages the leaderboards updated in real-time.


• 
  Basic user matchmaking package. Provides your project with server-side 1v1 matchmaking.


• 
  Extended user matchmaking package. Further customization of basic matchmaking that supports any number of users matched against each another.


• 
  Test messages package. Gives access to various client requests that allow measuring server performance and profiling important APIs.


• 
  Kongregate login package. Kongregate network login API was moved into a separate package from the core.


• 
  User session length stats package. Allows the collection and display of average user session length stats.

Additions:

• Large amount of server optimizations. In particular, user login and registration were rewritten to support much heavier load (with minor breaking changes detailed below).


• 
  Asynchronous database connections manager and API for asynchronous database queries. Used in the new user login and registration code.


• 
  Live client migration between slave server threads with support for automatic migration on client login.


• Editor and server support for static tables.


• Various clan module additions and fixes.


• 
  Macros for automating access to user attributes and variables.


• Ingame shop module item purchases stats collection and display.


• Editor support for stats dashboard.


• 
  Debug server compilation flags.

New cache server configuration variables:

• “asyncDatabase.threads” - Sets the amount of async database manager threads (default: 1)


• “asyncDatabase.connectionsPerThread” - Sets the amount of database connections per thread (default: 1)

New slave server configuration variables:

• “server.compressionMinSize” - Sets the minimum message size for compression to work (default: 512 bytes)

Breaking changes:

• cache: ModuleCache.loginPost(), ModuleCache.registerPost() now have additional parameter - SQL query function and run from the asynchronous worker thread


• 
  

  slave: Module hook renamed: “core/user.register” -> “core/user.registerPost”, Module.register() -> Module.registerPost()

  
  


• All editor templates renamed with “core/” prefix in front. For example,
  “form.header” -> “core/form.header”, etc. To fix editor compilation,
  open “index.hxml” and add “core/” prefix after @ symbol on each line.

Example (before):

--resource ../../../snipe/edit/www/tpl/form.header.htpl@form.header

--resource ../../../snipe/edit/www/tpl/form.footer.htpl@form.footer

After:

--resource ../../../snipe/edit/www/tpl/form.header.htpl@core/form.header

--resource ../../../snipe/edit/www/tpl/form.footer.htpl@core/form.footer

Important note:

You may see the following error message during server start:

Called from sys/db/Postgresql.hx line 405
Uncaught exception - load.c(357) : Primitive not found : npostgres@np_set_non_blocking(2)

It means that you need to replace your old “npostgres.ndll” file with the new one from the core containing new functions for asynchronous database calls.
