From 51da92ea1216e9d5139d03308618def2f9d4746a Mon Sep 17 00:00:00 2001 From: shyouhei Date: Thu, 2 Dec 2010 11:06:32 +0000 Subject: * vm.c (ruby_vm_at_exit): new API. This enables extension libs to hook a VM termination. Right now, because the VM we have is process global, most extensions do not deallocate resources and leave them to Operating System's reaping userland processes. But in a future we plan to have multiple VMs to run simultaneously in a single process (MVM project). At that stage we can no longer rely on OSes and have to manage every resources to be reclaimed properly. So it is. For a forward-compatibility reason this API is introduced now, encouraging you to be as gentle as you can for your resources; that is, tidy up your room. * include/ruby/vm.h: ditto. * vm_core.h (rb_vm_struct): new field. * vm.c (vm_init2): initialize above new field. * eval.c (ruby_cleanup): trigger those hooks. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@30050 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- eval.c | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'eval.c') diff --git a/eval.c b/eval.c index bbf66b3152..e54b5400c8 100644 --- a/eval.c +++ b/eval.c @@ -129,6 +129,9 @@ ruby_cleanup(volatile int ex) int nerr; void rb_threadptr_interrupt(rb_thread_t *th); void rb_threadptr_check_signal(rb_thread_t *mth); + int i; + rb_vm_t *vm = GET_VM(); + VALUE ary = (VALUE)&vm->at_exit; rb_threadptr_interrupt(th); rb_threadptr_check_signal(th); @@ -148,6 +151,13 @@ ruby_cleanup(volatile int ex) } POP_TAG(); + /* at_exit functions called here; any other place more apropriate + * for this purpose? let me know if any. */ + for (i=0; ierrinfo; PUSH_TAG(); if ((state = EXEC_TAG()) == 0) { -- cgit v1.2.3
