2026-05-08Introduce RMATCH_{BEG,END,NREGS} helpersJohn Hawthorn
These are internal-only helpers which can be used instead of the RMATCH_REGS struct directly. RMATCH_REGS is just a pointer offset from the RMatch VALUE itself, so this should not significantly affect codegen. The motivation for this is that it's both simpler, and should move us towards being able to replace the storage for RMATCH, and to be able to store the positions embedded instead of in separate malloc memory.
2026-03-06Improve comparison error message.Ernie Miller
In certain cases, things like Array#sort can result in a confusing error message. For instance where a and b are characters in a string, `"string"`: ```ruby array.sort { |a, b| string.index(a) <=> string.index(b) } ``` If one of the index calls returns nil, we will get "comparison of String with String failed", which is somewhat unhelpful, since it's easy to be confused, given that what is really being compared is a Fixnum or NilClass (the cause of the error). Yes, as far as Array#sort is concerned, the two characters are the things being sorted, but it's useful to call attention to the return value of the comparison in this case. This patch adds a "reason" argument to rb_cmperr, which will provide an error message of "comparison of String with String failed: comparator returned nil" in the case above, or, in the case of: ```ruby 1.upto('10').to_a ``` it will provide the message: "comparison of Fixnum with String failed: coercion was not possible"
2026-01-18Optimize File.join common use caseJean Boussier
`File.join` is a hotspot for common libraries such as Zeitwerk and Bootsnap. It has a fairly flexible signature, but 99% of the time it's called with just two (or a small number of) UTF-8 strings. If we optimistically optimize for that use case we can cut down a large number of type and encoding checks, significantly speeding up the method. The one remaining expensive check we could try to optimize is `str_null_check`. Given it's common to use the same base string for joining, we could memoize it. Also we could precompute it for literal strings. ``` compare-ruby: ruby 4.1.0dev (2026-01-17T14:40:03Z master 00a3b71eaf) +PRISM [arm64-darwin25] built-ruby: ruby 4.1.0dev (2026-01-18T12:10:38Z spedup-file-join 069bab58d4) +PRISM [arm64-darwin25] warming up.... | |compare-ruby|built-ruby| |:-------------|-----------:|---------:| |two_strings | 2.475M| 9.444M| | | -| 3.82x| |many_strings | 551.975k| 2.346M| | | -| 4.25x| |array | 514.946k| 522.034k| | | -| 1.01x| |mixed | 621.236k| 633.189k| | | -| 1.02x| ```

ASAN leaves a pointer to the fake frame on the stack; we can use the __asan_addr_is_in_fake_stack API to work out the extent of the fake stack and thus mark any VALUEs contained therein. [Bug #20001]

2023-12-10Change the semantics of rb_postponed_job_registerKJ Tsanaktsidis
Our current implementation of rb_postponed_job_register suffers from some safety issues that can lead to interpreter crashes (see bug #1991). Essentially, the issue is that jobs can be called with the wrong arguments. We made two attempts to fix this whilst keeping the promised semantics, but: * The first one involved masking/unmasking when flushing jobs, which was believed to be too expensive * The second one involved a lock-free, multi-producer, single-consumer ringbuffer, which was too complex The critical insight behind this third solution is that essentially the only user of these APIs are a) internal, or b) profiling gems. For a), none of the usages actually require variable data; they will work just fine with the preregistration interface. For b), generally profiling gems only call a single callback with a single piece of data (which is actually usually just zero) for the life of the program. The ringbuffer is complex because it needs to support multi-word inserts of job & data (which can't be atomic); but nobody actually even needs that functionality, really. So, this comit: * Introduces a pre-registration API for jobs, with a GVL-requiring rb_postponed_job_prereigster, which returns a handle which can be used with an async-signal-safe rb_postponed_job_trigger. * Deprecates rb_postponed_job_register (and re-implements it on top of the preregister function for compatability) * Moves all the internal usages of postponed job register pre-registration

2023-04-06Update VPATH for socket, & dependenciesMatt Valentine-House
The socket extensions rubysocket.h pulls in the "private" include/gc.h, which now depends on vm_core.h. vm_core.h pulls in id.h when tool/update-deps generates the dependencies for the makefiles, it generates the line for id.h to be based on VPATH, which is configured in the extconf.rb for each of the extensions. By default VPATH does not include the actual source directory of the current Ruby so the dependency fails to resolve and linking fails. We need to append the topdir and top_srcdir to VPATH to have the dependancy picked up correctly (and I believe we need both of these to cope with in-tree and out-of-tree builds). I copied this from the approach taken in https://github.com/ruby/ruby/blob/master/ext/objspace/extconf.rb#L3 Notes: Merged: https://github.com/ruby/ruby/pull/7393

2022-11-10Transition shape when object's capacity changesJemma Issroff
This commit adds a `capacity` field to shapes, and adds shape transitions whenever an object's capacity changes. Objects which are allocated out of a bigger size pool will also make a transition from the root shape to the shape with the correct capacity for their size pool when they are allocated. This commit will allow us to remove numiv from objects completely, and will also mean we can guarantee that if two objects share shapes, their IVs are in the same positions (an embedded and extended object cannot share shapes). This will enable us to implement ivar sets in YJIT using object shapes. Co-Authored-By: Aaron Patterson <tenderlove@ruby-lang.org> Notes: Merged: https://github.com/ruby/ruby/pull/6699

2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues. Notes: Merged: https://github.com/ruby/ruby/pull/3365
