2025-10-28ZJIT: Specialize Array#pop for no argument case (#14933)Aiden Fox Ivey
Fixes https://github.com/Shopify/ruby/issues/814 This change specializes the case of calling `Array#pop` on a non frozen array with no arguments. `Array#pop` exists in the non-inlined C function list in the ZJIT SFR performance burndown list. If in the future it is helpful, this patch could be extended to support the case where an argument is provided, but this initial work seeks to elide the ruby frame normally pushed in the case of `Array#pop` without an argument.

2025-10-28[ruby/json] Use Vector API in the Java ExtensionScott Myron
Overview This PR uses the [jdk.incubator.vector module](https://docs.oracle.com/en/java/javase/20/docs/api/jdk.incubator.vector/jdk/incubator/vector/package-summary.html) as mentioned in [issue #739](https://github.com/ruby/json/issues/739) to accelerate generating JSON with the same algorithm as the C extension. The PR as it exists right now, it will attempt to build the `json.ext.VectorizedEscapeScanner` class with a target release of `16`. This is the first version of Java with support for the `jdk.incubator.vector` module. The remaining code is built for Java 1.8. The code will attempt to load the `json.ext.VectorizedEscapeScanner` only if the `json.enableVectorizedEscapeScanner` system property is set to `true` (or `1`). I'm not entirely sure how this is packaged / included with JRuby so I'd love @byroot and @headius's (and others?) thought about how to potential package and/or structure the JARs. I did consider adding the `json.ext.VectorizedEscapeScanner` to a separate `generator-vectorized.jar` but I thought I'd solicit feedback before spending any more time on the build / package process. Benchmarks Machine M1 Macbook Air Note: I've had trouble modifying the `compare.rb` I was using for the C extension to work reliability with the Java extension. I'll probably spend more time trying to get it to work, but as of right now these are pretty raw benchmarks. Below are two sample runs of the real-world benchmarks. The benchmarks are much more variable then the C extension for some reason. I'm not sure if HotSpot is doing something slightly different per execution.

Replace fixed-sized RSA keys with the generic rsa-{1,2,3}.pem keys. Those test cases do not depend on specific keys or key sizes, and just need several different keys. Replace DSA keys with EC keys so that we can run more tests in the FIPS mode, which do not seem to support DSA anymore. Also, clean up duplicate test cases using very small keys or obsolete hash functions. rake test_fips no longer skips those test cases. https://github.com/ruby/openssl/commit/3f3105429a

2025-10-27Fix segfault when moving nested objects between ractors during GCJoshua Young
Fixes a segmentation fault when moving nested objects between ractors with GC stress enabled and YJIT. The issue is a timing problem: `move_enter` allocates new object shells but leaves their contents uninitialized until `move_leave` copies the actual data. If GC runs between these steps (which GC stress makes likely), it tries to follow what appear to be object pointers but are actually uninitialized memory, encountering null or invalid addresses. The fix zero-initializes the object contents immediately after allocation in `move_enter`, ensuring the GC finds safe null pointers instead of garbage data. The crash reproduced most consistently with nested hashes and YJIT, likely because nested structures create multiple uninitialized objects simultaneously while YJIT's memory usage increases the probability of GC triggering during moves.

2025-10-25[ruby/json] Fix concurrent usage of JSON::Coder#dumpJean Boussier
Fix: https://github.com/rails/rails/commit/90616277e3d8fc46c9cf35d6a7470ff1ea0092f7#r168784389 Because the `depth` counter is inside `JSON::State` it can't be used concurrently, and in case of a circular reference the counter may be left at the max value. The depth counter should be moved outside `JSON_Generator_State` and into `struct generate_json_data`, but it's a larger refactor. In the meantime, `JSON::Coder` calls `State#generate_new` so I changed that method so that it first copy the state on the stack. https://github.com/ruby/json/commit/aefa671eca

2025-10-22[ruby/prism] Make error and snapshot tests multi-version awareEarlopain
This one has been on my mind for a while now. Currently, there are only tests against the latest syntax version. This changes the snapshot structure as follows: * Snapshots at their current location are tested against all syntax versions * Snapshots inside a version folder like "3.3" are tested against all versions starting from that version * Snapshots inside a version folder like "3.3-4.2" are tested against all versions in the given range. This makes sure that as new syntax is added, older versions still work as expected. I also added a few tests for now valid syntax that should be invalid in older versions (and the other way around as well) These tests run really fast. So even though it does 3x the work for these, I am still able to run the whole test suite in just 11 seconds. https://github.com/ruby/prism/commit/5191b1aa68

I tried to fix this by checking whether the two previous instructions are labeled.
2025-10-17[rubygems/rubygems] :Revamp CmakeBuilder to fix the issues described in ↵Charlie Savage
#8572. Specifically: * Correctly pass command line arguments to CMake * Call CMake twice - once to configure a project and a second time to build (which is the standard way to use CMake). This fixes the previously incorrect assumption that CMake generates a Make file. * Update the tests to specify a CMake minimum version of 3.26 (which is already two years old). 3.26 is a bit arbritary but it aligns with Rice, and updates from the ancient 3.5 version being used (which CMake generates a warning message saying stop using it!) * Update the CMake call to use CMAKE_RUNTIME_OUTPUT_DIRECTORY and CMAKE_LIBRARY_OUTPUT_DIRECTORY to tell CMake to copy compiled binaries to the a Gem's lib directory. Note the updated builder took inspiration from the Cargo Builder, meaning you first create an instance of CmakeBuilder versus just calling class methods. https://github.com/rubygems/rubygems/commit/9e248d4679

2025-10-16[ruby/prism] Add support for `Prism.parse(foo, version: "current")`Earlopain
The docs currently say to use `Prism.parse(foo, version: RUBY_VERSION)` for this. By specifying "current" instead, we can have prism raise a more specifc error. Note: Does not use `ruby_version` from `ruby/version.h` because writing a test for that is not really possible. `RUBY_VERSION` is nicely stubbable for both the c-ext and FFI backend. https://github.com/ruby/prism/commit/9c5cd205cf
