2022-02-09objspace: Hide identhash containing internal objsJohn Hawthorn
Inside ObjectSpace.reachable_objects_from we keep an internal identhash in order to de-duplicate reachable objects when wrapping them as InternalObject. Previously this hash was not hidden, making it possible to leak references to those internal objects to Ruby if using ObjectSpace.each_object. This commit solves this by hiding the hash. To simplify collection of values, we instead now just use the hash as a set of visited objects, and collect an Array (not hidden) of values to be returned.

2021-12-13Remove `NODE_DASGN_CURR` [Feature #18406]Nobuyoshi Nakada
This `NODE` type was used in pre-YARV implementation, to improve the performance of assignment to dynamic local variable defined at the innermost scope. It has no longer any actual difference with `NODE_DASGN`, except for the node dump. Notes: Merged: https://github.com/ruby/ruby/pull/5251

2021-01-05enable constant cache on ractorsKoichi Sasada
constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed. Notes: Merged: https://github.com/ruby/ruby/pull/4022
2020-12-24Expose atomic operation macros with RUBY prefixNobuyoshi Nakada
Now we need atomic operations, which are lighter than mutex, more widely for extension libraries because of Ractor. Notes: Merged: https://github.com/ruby/ruby/pull/3983
2020-10-06Prevent objects from moving while iterating the heapAaron Patterson
This iterator uses an st_table, but if objects move the references in the st table won't be updated. This patch just changes the st table to an identity hash. Notes: Merged: https://github.com/ruby/ruby/pull/3634
2020-10-03Fix ObjectSpace.dump(obj, output: :stdout)Kazuhiro NISHIYAMA
RDoc says `ObjectSpace.dump(obj, output: :stdout) # => nil`, but it returns STDOUT since fbba6bd4e3dff7a61965208fecae908f10c4edbe. I think it is unintentional change. Notes: Merged: https://github.com/ruby/ruby/pull/3620

2020-09-28Refactor common heap iteration codeAaron Patterson
We have code common to all heap iteration paths in this file. Refactor such that we keep ASAN checks and flags checks in one place Notes: Merged: https://github.com/ruby/ruby/pull/3592
2020-09-28Fix ASAN support when invalidating CCsAaron Patterson
Again, this code is walking the heap. Empty slots can be poisoned, so we need to unpoison before checking the type Notes: Merged: https://github.com/ruby/ruby/pull/3592
2020-09-28Make ext/objspace ASAN friendlyAaron Patterson
ext/objspace iterates over the heap, but some slots in the heap are poisoned, so we need to take care of that when running with ASAN Notes: Merged: https://github.com/ruby/ruby/pull/3592
2020-09-25Return nil when argument to ObjectSpace.internal_class_of is T_IMEMOAlan Wu
The added test case crashes the interpreter because it makes ObjectSpace.internal_class_of return the second VALUE slot of an AST imemo object. The second VALUE slot of `struct rb_ast_struct` is not a VALUE and not a pointer to a Ruby object. Notes: Merged: https://github.com/ruby/ruby/pull/3503
2020-09-15Parse ObjectSpace.dump_all / dump arguments in Ruby to avoid allocation noiseJean Boussier
[Feature #17045] ObjectSpace.dump_all should allocate as little as possible in the GC heap Up until this commit ObjectSpace.dump_all allocates two Hash because of `rb_scan_args`. It also can allocate a `File` because of `rb_io_get_write_io`. These allocations are problematic because `dump_all` dumps the Ruby heap, so it should try modify as little as possible what it is observing. Notes: Merged: https://github.com/ruby/ruby/pull/3530

The two main optimization are: - buffer writes for improved performance - avoid formatting functions when possible ``` | |compare-ruby|built-ruby| |:------------------|-----------:|---------:| |dump_all_string | 1.038| 195.925| | | -| 188.77x| |dump_all_file | 33.453| 139.645| | | -| 4.17x| |dump_all_dev_null | 44.030| 278.552| | | -| 6.33x| ``` Notes: Merged: https://github.com/ruby/ruby/pull/3420
2020-09-09Add a :since option to dump_allJean Boussier
This is useful to see what a block of code allocated, e.g. ``` GC.start GC.disable ObjectSpace.trace_object_allocations do # run some code end gc_gen = GC.count allocations = ObjectSpace.dump_all(output: :file, since: gc_gen) GC.enable GC.start retentions = ObjectSpace.dump_all(output: :file, since: gc_gen) ``` Notes: Merged: https://github.com/ruby/ruby/pull/3368

It seems almost no internal codes use RHASH_TBL any longer. Why not just eliminate it entirely, so that the macro can be purely ext-only. Notes: Merged: https://github.com/ruby/ruby/pull/3426
2020-08-18Update references when tracing allocationsAaron Patterson
The allocation tracing code keeps essentially a weak reference to objects that have been allocated (storing the allocation information along with the weak ref). Compacting the heap would break references in this weak map, so the wrong values could be returned. This commit just updates the values in the weak ref in order to fix the allocation tracing book keeping Notes: Merged: https://github.com/ruby/ruby/pull/3429
2020-08-17Fix method name escaping in ObjectSpace.dumpJohn Hawthorn
It's possible to define methods with any name, even if the parser doesn't support it and it can only be used with ex. send. This fixes an issue where invalid JSON was output from ObjectSpace.dump when a method name needed escaping. Notes: Merged: https://github.com/ruby/ruby/pull/3383
