2024-11-14rb_raise when attempting to set the GC implementation nameMatt Valentine-House
Instead of silently ignoring the key, we should raise to clearly tell the user that this key is read-only. Notes: Merged: https://github.com/ruby/ruby/pull/11872
2024-11-14Include the currently active GC in RUBY_DESCRIPTIONMatt Valentine-House
This will add +MOD_GC to the version string and Ruby description when Ruby is compiled with shared gc support. When shared GC support is compiled in and a GC module has been loaded using RUBY_GC_LIBRARY, the version string will include the name of the currently active GC as reported by the rb_gc_active_gc_name function in the form +MOD_GC[gc_name] [Feature #20794] Notes: Merged: https://github.com/ruby/ruby/pull/11872

2024-11-11Fix regex timeout double-free after stack_doubleJohn Hawthorn
As of 10574857ce167869524b97ee862b610928f6272f, it's possible to crash on a double free due to `stk_alloc` AKA `msa->stack_p` being freed twice, once at the end of match_at and a second time in `FREE_MATCH_ARG` in the parent caller.

2024-11-08Fix race condition in test_self_stopKJ Tsanaktsidis
This test was relying on a sleep to synchronise the parent and child processes. By having the child be the process that stops itself with SIGSTOP, instead of the parent, we can actually properly wait for that using waitpid2 and be notified of the stop. This use of sleep to synchronise processes is potentially flaky and caused failures under rr's `--chaos` mode. Notes: Merged: https://github.com/ruby/ruby/pull/12042
2024-11-08Fix update_coderange for binary stringsJohn Hawthorn
Although a binary (aka ASCII-8BIT) string will never have a broken coderange, it still has to differentiate between "valid" and "7bit". On Ruby 3.4/trunk this problem is masked because we now clear the coderange more agressively in rb_str_resize, and we happened to always be strinking this string, but we should not assume that. On Ruby 3.3 this created strings where `ascii_only?` was true in cases it shouldn't be as well as other problems.

2024-11-08Fix memory leak in prism when syntax error in iseq compilationPeter Zhu
If there's a syntax error during iseq compilation then prism would leak memory because it would not free the pm_parse_result_t. This commit changes pm_iseq_new_with_opt to have a rb_protect to catch when an error is raised, and return NULL and set error_state to a value that can be raised by calling rb_jump_tag after memory has been freed. For example: 10.times do 10_000.times do eval("/[/=~s") rescue SyntaxError end puts `ps -o rss= -p #{$$}` end Before: 39280 68736 99232 128864 158896 188208 217344 246304 275376 304592 After: 12192 13200 14256 14848 16000 16000 16000 16064 17232 17952 Notes: Merged: https://github.com/ruby/ruby/pull/12036

#set_string (#11640) The current implementation of `IO::Buffer#copy` and `#set_string` has an undefined behavior when the source and destination memory overlaps, due to the underlying use of the `memcpy` C function.

2024-11-06Fix flakiness in TestGc#test_thrashing_for_young_objectsKJ Tsanaktsidis
I caught a reproduction of this test failing under rr, and was able to replay it to isolate the failure. The call to `before_stat_heap = GC.stat_heap` is itself allocating a hash, which in unlucky circumstances can result in a new page being allocated and thus `before_stats[:heap_allocated_pages]` no longer equals `after_stats[:heap_allocated_pages]`. The solution is to use the form of GC.stat/stat_heap which takes a hash as an argument, and thus needs to perform no Ruby allocations itself. Notes: Merged: https://github.com/ruby/ruby/pull/11997

2024-11-06`Warning[:strict_unused_block]`Koichi Sasada
to show unused block warning strictly. ```ruby class C def f = nil end class D def f = yield end [C.new, D.new].each{|obj| obj.f{}} ``` In this case, `D#f` accepts a block. However `C#f` doesn't accept a block. There are some cases passing a block with `obj.f{}` where `obj` is `C` or `D`. To avoid warnings on such cases, "unused block warning" will be warned only if there is not same name which accepts a block. On the above example, `C.new.f{}` doesn't show any warnings because there is a same name `D#f` which accepts a block. We call this default behavior as "relax mode". `strict_unused_block` new warning category changes from "relax mode" to "strict mode", we don't check same name methods and `C.new.f{}` will be warned.

If there is a syntax error, there could be an ast_node in the result. This could get leaked if there is a syntax error so parsing could not complete (parsed is not set to true).

2024-10-03Rename size_pool -> heapMatt Valentine-House
Now that we've inlined the eden_heap into the size_pool, we should rename the size_pool to heap. So that Ruby contains multiple heaps, with different sized objects. The term heap as a collection of memory pages is more in memory management nomenclature, whereas size_pool was a name chosen out of necessity during the development of the Variable Width Allocation features of Ruby. The concept of size pools was introduced in order to facilitate different sized objects (other than the default 40 bytes). They wrapped the eden heap and the tomb heap, and some related state, and provided a reasonably simple way of duplicating all related concerns, to provide multiple pools that all shared the same structure but held different objects. Since then various changes have happend in Ruby's memory layout: * The concept of tomb heaps has been replaced by a global free pages list, with each page having it's slot size reconfigured at the point when it is resurrected * the eden heap has been inlined into the size pool itself, so that now the size pool directly controls the free_pages list, the sweeping page, the compaction cursor and the other state that was previously being managed by the eden heap. Now that there is no need for a heap wrapper, we should refer to the collection of pages containing Ruby objects as a heap again rather than a size pool Notes: Merged: https://github.com/ruby/ruby/pull/11771
