The author describes building Dumpster, a cycle-detecting garbage collector for Rust — a language designed to avoid GC — by leveraging Drop, custom traits, and unsafe atomics to handle shared ownership cycles that Rc/Arc cannot free.
OpenJDK 发布 JDK 28 版本规划页面,目前包含 10 个已确定的 JEP,涵盖值对象预览、结构化并发、AOT 编译、ZGC 性能改进及 JSON API 孵化器等特性。
A deep-dive investigation shows that Go's stop-the-world GC pauses can balloon to ~40ms when GC metadata pages are evicted to swap, with page faults during GC bookkeeping accounting for most of the delay (39 of 40ms across 228 faults).
A detailed write-up by Justin Ethier explaining how the Cyclone Scheme compiler was built, covering source-to-source transformations, CPS and closure conversion, C code generation, and a hybrid Cheney-style garbage collector.
这篇博客文章讨论了单调函数的最小/最大不动点在编译与程序分析中的作用,指出人类编写的算法常默认收敛到错误的极端不动点,并用活跃变量分析、引用计数与类型传播举例说明如何通过正确的初始值找到真正需要的不动点。
This paper formalizes semantic shadowing in mutable RAG and introduces GC-Mem, a temporal dominance-based protocol that resolves conflicts and recovers over 90% accuracy.
This blog post from V8 introduces Oilpan, a high-performance garbage collector for C++ used in Chromium, detailing its principles, features, and upcoming move to a library for broader developer access.
The article investigates why Arrays.fill is 265 times slower on G1GC compared to ParallelGC, tracing the issue to JIT-generated code and memory barriers through detailed profiling and assembly analysis.
Porffor, a compiler, is transitioning from pre-alpha to alpha on August 11th with major updates including self-hosting, a core rewrite, garbage collection, and significant performance improvements.
Claude Code CLI has been optimized to reduce CPU usage by 2x at p99 by updating Bun's garbage collector to run only when the process is idle.
The author details performance improvements to the garbage collector for their toy programming language Plush, focusing on optimizing the copying algorithm to reduce collection time.
TLA+ is a model checking tool that explores all state interleavings to find bugs in distributed systems; it helped improve safety in Depot Registry's garbage collector by identifying a missed bug through formal verification.
JDK 27 introduces notable changes to HotSpot's stop-the-world garbage collectors, most significantly JEP 523 making G1 the default GC in all environments, alongside various improvements, refactorings, and bug fixes.
A technical article explains the true performance costs of garbage collection, contrasting tracing GCs, reference counting, and compile-time memory management in languages like Go, Java, Rust, Swift, and Python.
Wasmtime 47 enables Wasm GC and exceptions proposals by default, making it easier for high-level languages with garbage collection and exceptions to target WebAssembly efficiently.
The second edition of 'The Garbage Collection Handbook' updates the authoritative reference on automatic memory management, covering new hardware, software, and algorithm developments.
This master's thesis at Uppsala University, done in collaboration with Oracle, investigates reducing the overhead of weak reference processing in the ZGC garbage collector by proposing three pipeline modifications and an alternative annotated-field mechanism.
Python 3.14 introduced an incremental garbage collector that was later reverted in 3.14.5 due to memory pressure reports. This article explains the changes, their impact, and the controversy around the revert.
Fil-C 0.679 is a new release of a fanatically compatible memory-safe implementation of C and C++ that uses concurrent garbage collection and invisible capabilities to prevent all memory safety errors without escape hatches.
David Crawshaw argues that while the industry invests in Rust's lack of GC, Jane Street's OCaml with OxCaml demonstrates that GC is beneficial for most code paths, with only 1% needing performance optimization.
