2024-01-15Improve behavioural consistency of unallocated (zero length) `IO::Buffer`. ↵Samuel Williams
(#9532) This makes the behaviour of IO::Buffer.new(0) and IO::Buffer.new.slice(0, 0) consistent. Fixes https://bugs.ruby-lang.org/issues/19542 and https://bugs.ruby-lang.org/issues/18805.
2023-12-27Fix Window private file mapping unlink EACCES issue. (#9358)Samuel Williams
* Don't return early. * Add missing `mapping` assignment. * Make debug logs conditional.
2023-12-25Correctly release the underlying file mapping. (#9340)Samuel Williams
* Avoiding using `Tempfile` which was retaining the file preventing it from unlinking.
2023-12-25IO::Buffer improvements and documentation. (#9329)Samuel Williams
* Restore experimental warnings. * Documentation and code structure improvements. * Improved validation of flags, clarified documentation of argument handling. * Remove inconsistent use of `Example:` and add example to `null?`. * Expose `IO::Buffer#private?` and add test.

Benchmark: ``` require "benchmark" puts(Benchmark.measure do ary = 1_000_000.times.map { IO::Buffer.for("") } 10.times { GC.start(full_mark: false) } end) ``` Before: ``` 14.330119 0.051497 14.381616 ( 14.445106) ``` After: ``` 7.481152 0.040166 7.521318 ( 7.535209) ```
2023-12-12Use xfree for IO::BufferPeter Zhu
Since IO::Buffer is allocated using TypedData_Make_Struct, it must use xfree to free the buffer otherwise it will cause more major GC to run. Example: ``` 10.times do 1_000_000.times { IO::Buffer.new(0) } puts "oldmalloc_increase_bytes: #{GC.stat(:oldmalloc_increase_bytes)}, major_gc_count: #{GC.stat(:major_gc_count)}" end ``` Before: ``` oldmalloc_increase_bytes: 14904176, major_gc_count: 3 oldmalloc_increase_bytes: 2399424, major_gc_count: 5 oldmalloc_increase_bytes: 5204640, major_gc_count: 6 oldmalloc_increase_bytes: 2199936, major_gc_count: 7 oldmalloc_increase_bytes: 34199936, major_gc_count: 7 oldmalloc_increase_bytes: 24223360, major_gc_count: 8 oldmalloc_increase_bytes: 5967616, major_gc_count: 9 oldmalloc_increase_bytes: 37967616, major_gc_count: 9 oldmalloc_increase_bytes: 9689792, major_gc_count: 10 oldmalloc_increase_bytes: 41689792, major_gc_count: 10 ``` After: ``` oldmalloc_increase_bytes: 117392, major_gc_count: 2 oldmalloc_increase_bytes: 26128, major_gc_count: 2 oldmalloc_increase_bytes: 71600, major_gc_count: 2 oldmalloc_increase_bytes: 117072, major_gc_count: 2 oldmalloc_increase_bytes: 17296, major_gc_count: 2 oldmalloc_increase_bytes: 62768, major_gc_count: 2 oldmalloc_increase_bytes: 108240, major_gc_count: 2 oldmalloc_increase_bytes: 153712, major_gc_count: 2 oldmalloc_increase_bytes: 53936, major_gc_count: 2 oldmalloc_increase_bytes: 99408, major_gc_count: 2 ```

2023-09-14Fix `io_buffer_get_string` default length computation. (#8427)Samuel Williams
* Fix `io_buffer_get_string` default length computation. When an offset bigger than the size is given, the resulting length will be computed incorrectly. Raise an argument error in this case. * Validate all arguments. Notes: Merged-By: ioquatix <samuel@codeotaku.com>

2023-03-25IO::Buffer#resize: Free internal buffer if new size is zero (#7569)Kasumi Hanazuki
`#resize(0)` on an IO::Buffer with internal buffer allocated will result in calling `realloc(data->base, 0)`. The behavior of `realloc` with size = 0 is implementation-defined (glibc frees the object and returns NULL, while BSDs return an inaccessible object). And thus such usage is deprecated in standard C (upcoming C23 will make it UB). To avoid this problem, just `free`s the memory when the new size is zero.
