[Dotgnu-libjit] PATCH: Don't leak function signatures when contexts are destroyed.

[GARCIA DE SORIA LUCENA, JUAN JESUS]

Hi everyone.

 

We run libjit in some long-running servers that actually compile runtime-generated expressions. Those expressions are generated, evaluated (once or more times), and then destroyed.

 

When a given _expression_ gets evaluated for the second time, it's probable that it will be reused more times, so we perform some high level optimizations on its _expression_ tree, and the compile it to machine code via libjit. When the _expression_ is destroyed, the jit_context_t in which it was created gets released (we create a separate context per _expression_).

 

We found that libjit was leaking memory (the function signature) with each context. I attach a patch that fixes it by calling jit_type_free() on the signature in _jit_function_destroy().

 

 

Regards,

 

   Juan Jesus.
