objspace_dump.c: refine output

2013-11-14T16:06:09+00:00

* ext/objspace/objspace_dump.c (dump_output): allow IO object as
  output, and use Tempfile.create and return open file instead of
  mkstemp() and path name for :file output.
  [ruby-core:58266] [Bug #9102]
* test/objspace/test_objspace.rb (TestObjSpace#dump_my_heap_please):
  remove temporary output file.

* test/objspace/test_objspace.rb (TestObjSpace#test_dump_all): add
  assertion for output to temporary file.

* test/objspace/test_objspace.rb (test_dump_all): Make the test string

2013-11-09T11:53:02+00:00

  shorter to be an embedded string on 32bit environment as well as
  64bit environment.

* ext/objspace/object_tracing.c: Add experimental methods to dump

2013-11-08T17:06:55+00:00

objectspace as json: ObjectSpace.dump_all and ObjectSpace.dump(obj).
These methods are useful for debugging reference leaks and memory growth
in large ruby applications. [Bug #9026] [ruby-core:57893] [Fixes GH-423]

* ext/objspace/objspace.c: add a new method `reachable_objects_from_root'.

2013-10-16T06:13:41+00:00

  ObjectSpace.reachable_objects_from_root returns all objects refered
  from root (called "root objects").
  This feature is for deep object analysis.
* test/objspace/test_objspace.rb: add a test.

vm_trace.c: fix infinite hook

2013-10-10T18:36:54+00:00

* thread.c (rb_threadptr_execute_interrupts): flush postponed job only
  once at last.
* vm_trace.c (rb_postponed_job_flush): defer calling postponed jobs
  registered while flushing to get rid of infinite reentrance of
  ObjectSpace.after_gc_start_hook.  [ruby-dev:47400] [Bug #8492]

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43245 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* ext/objspace/object_tracing.c: add new 3 methods to control tracing.

2013-09-30T08:17:30+00:00

* ObjectSpace::trace_object_allocations_start
* ObjectSpace::trace_object_allocations_stop
* ObjectSpace::trace_object_allocations_clear
  And some refactoring.
* test/objspace/test_objspace.rb: add a test for new methods.
* NEWS: add a description for new methods.

* ext/objspace/object_tracing.c: fix a bug reported at

2013-05-28T03:36:34+00:00

  "[ruby-core:55182] [ruby-trunk - Bug #8456][Open] Sugfault in Ruby Head"
  Care about the case TracePoint#path #=> `nil'.
* ext/objspace/object_tracing.c: add two new methods:
* ObjectSpace.allocation_class_path(o)
* ObjectSpace.allocation_method_id(o)
  They are not useful for Object.new because they are always
  "Class" and :new.
  To trace more useful information, we need to maintain call-tree
  using call/return hooks, which is implemented by
  ll-prof 
* test/objspace/test_objspace.rb: add a test.

* ext/objspace/objspace.c: support ObjectSpace.trace_object_allocations.

2013-05-27T10:01:45+00:00

  Read the following test to know HOWTO.
  This feature is a sample of RUBY_INTERNAL_EVENT.
* test/objspace/test_objspace.rb: add a test.
* ext/objspace/object_tracing.c: ditto.
* gc.c (rb_gc_count): add. THis function returns GC count.
* internal.h: add decl. of rb_gc_count(). Same as `GC.count'.
