SourceMod 1.1.0 Release Notes

JIT Changes

SourcePawn's language runtime has undergone some major facelifts. All SourceMod-specific code has been pulled out and cleaned up so it can be embedded in other applications.

User Changes

The concept of "debug mode" has been removed. Debug mode is now always on. The runtime has been reworked so this is no longer a performance loss.

This decision was made partially to clean up some very inefficient code, but it's also for support. Users no longer have to manually toggle or reconfigure plugins before reporting errors.

The JIT (just-in-time compiler) is responsible for converting plugins to machine code for speed. Previously, plugins were translated to machine code all at once on load. In SourceMod 1.1 this has changed. Plugins are now incrementally compiled as functions get called for the first time. This might help load time, but was actually done to improve internal logic.

Developer Changes

Dependence on private or internal structures has been eliminated. Plugins are now represented by IPluginRuntime structures, and contexts are now solely represented by an IPluginContext. The sp_plugin_t and sp_context_t structures have been removed.

A huge number of functions in IPluginContext have been deprecated and moved to IPluginRuntime as part of this effort. Contexts are now intended only to represent a thread of execution. Similarly, function invocation is now defined as being invocation of a particular IPluginFunction combined with an IPluginContext (a default contexts exists for compatibility).

The ISourcePawnEngine API has been deprecated in favor of ISourcePawnEngine2. The new API reflects the restructuring. For example, it provides a single entry point for creating an IPluginRuntime from a file.
