2025-08-21Add `Math.log1p` and `Math.expm1`Yusuke Endoh
This commit adds two new methods to the `Math` module: * `Math.log1p(x)`: Computes `Math.log(x + 1)` * `Math.expm1(x)`: Computes `Math.exp(x) - 1` These methods are often more accurate than the straightforward computation, especially when `x` is close to zero. The corresponding functions, `log1p` and `expm1`, are defined in the C99 standard math library. [Feature #21527]
2025-08-19ZJIT: Prepare for rb_range_new() calling <=>Alan Wu
gen_prepare_call_with_gc() was not enough because of the rb_funcall() usage in range_init(). Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com> Co-authored-by: Max Bernstein <rubybugs@bernsteinbear.com>
2025-08-19Fix special consts unit tests for i686 (#14271)Max Bernstein
32-bit platforms do not have flonum and something about the static symbol test was flaky.
2025-08-19ZJIT: Compile toregexp (#14200)Daniel Colson
`toregexp` is fairly similar to `concatstrings`, so this commit extracts a helper for pushing and popping operands on the native stack. There's probably opportunity to move some of this into lir (e.g. Alan suggested a push_many that could use STP on ARM to push 2 at a time), but I might save that for another day.

2025-08-15Fix tests using assert_raise_with_message on US-ASCII systemsPeter Zhu
On systems where the Encoding.default_internal defaults to US-ASCII instead of UTF-8, some tests using assert_raise_with_message can fail since it no longer changes Encoding.default_internal in 79f5202. This tests explicitly uses EnvUtil.with_default_internal on systems where these tests fail.

2025-08-15Don't change Encoding.default_internal in assert_raise_with_messagePeter Zhu
For most tests (except two), we don't need to change Encoding.default_internal in assert_raise_with_message. We're trying to run the test suite across multiple Ractors and modifying Encoding.default_internal can cause other concurrently running tests to fail.

Generally I have been good about safely accessing the tokens but failed to properly guard against no tokens in places where it could theoretically happen through invalid syntax.

2025-08-13ZJIT: Fix `ObjToString` rewrite (#14196)Stan Lo
ZJIT: Fix ObjToString rewrite Currently, the rewrite for `ObjToString` always replaces it with a `SendWithoutBlock(to_s)` instruction when the receiver is not a string literal. This is incorrect because it calls `to_s` on the receiver even if it's already a string. This change fixes it by: - Avoiding the `SendWithoutBlock(to_s)` rewrite - Implement codegen for `ObjToString`
2025-08-13imemo_fields: store owner object in RBasic.klassJean Boussier
It is much more convenient than storing the klass, especially when dealing with `object_id` as it allows to update the id2ref table without having to dereference the owner, which may be garbage at that point.

2025-08-12Allow encodings to be autoloaded through transcoding functionsLuke Gruber
Make sure VM lock is not held when calling `load_transcoder_entry`, as that causes deadlock inside ractors. `String#encode` now works inside ractors, among others. Atomic load the rb_encoding_list Without this, wbcheck would sometimes hit a missing write barrier.

2025-08-12set.c: Store `set_table->bins` at the end of `set_table->entries`Jean Boussier
This saves one pointer in `struct set_table`, which would allow `Set` objects to still fit in 80B TypedData slots even if RTypedData goes from 32B to 40B large. The existing set benchmark seem to show this doesn't have a very significant impact. Smaller sets are a bit faster, larger sets a bit slower. It seem consistent over multiple runs, but it's unclear how much of that is just error margin. ``` compare-ruby: ruby 3.5.0dev (2025-08-12T02:14:57Z master 428937a536) +YJIT +PRISM [arm64-darwin24] built-ruby: ruby 3.5.0dev (2025-08-12T07:22:26Z set-entries-bounds da30024fdc) +YJIT +PRISM [arm64-darwin24] warming up........ | |compare-ruby|built-ruby| |:------------------------|-----------:|---------:| |new_0 | 15.459M| 15.823M| | | -| 1.02x| |new_10 | 3.484M| 3.574M| | | -| 1.03x| |new_100 | 546.992k| 564.679k| | | -| 1.03x| |new_1000 | 49.391k| 48.169k| | | 1.03x| -| |aref_0 | 18.643M| 19.350M| | | -| 1.04x| |aref_10 | 5.941M| 6.006M| | | -| 1.01x| |aref_100 | 822.197k| 814.219k| | | 1.01x| -| |aref_1000 | 83.230k| 79.411k| | | 1.05x| -| ```
2025-08-12[ruby/openssl] pkey: skip tests using invalid keys in the FIPS modeKazuki Yamaguchi
In OpenSSL's master branch, importing/loading a key in the FIPS mode automatically performs a pair-wise consistency check. This breaks tests for OpenSSL::PKey::EC#check_key and DH#params_ok? as they use deliberately invalid keys. These methods would not be useful in the FIPS mode anyway.

gc_config_set returned rb_gc_impl_config_get, but gc_config_get also added the implementation key to the return value. This caused the return value of GC.config to differ depending on whether the optional hash argument is provided or not.
