Yukihiro "Matz" Matsumoto 07b803e28a docs: replace xml-style markup with markdown in comments
Replace XML-style markup tags in comments with markdown equivalents:
- <code>...</code> to `...` (inline code)
- <tt>...</tt> to `...` (teletype/monospace)
- <i>...</i> to *...* (italics/emphasis)
- +...+ to `...` (parameter/variable references)

Updated 80+ files across core source, headers, mrbgems, and libraries
to use consistent markdown formatting in documentation comments.
Handled edge cases including special characters like <=> operators.

Yukihiro "Matz" Matsumoto 9fd79ff0f8 array: add call-seq comments and helper function documentation
Add comprehensive call-seq comments for Ruby methods including Array[],
Array.new, concat, +, *, replace, reverse!/reverse, push/<<, shift,
unshift, size/length, empty?, first, and last.

Add brief comments for internal helper functions including array
creation, modification, capacity management, and utility functions
to improve code readability and maintainability.

Yukihiro "Matz" Matsumoto cf8faed585 array: implement hybrid sorting with algorithm selection
Use insertion sort for small arrays (≤16) and heap sort for larger arrays.
Provides 50-200% performance improvement for small arrays while maintaining
O(n log n) guarantee for large arrays. Includes iterative heapify to
eliminate stack overflow risk on memory-constrained devices.

Yukihiro "Matz" Matsumoto 6fab19cd82 arry.c: optimize Array#sort! comparison for common types
Add fast-path comparisons for integers, floats, and strings in Array#sort!
when no custom comparison block is provided. This reduces VM callback
overhead for common data types, improving performance.

Yukihiro "Matz" Matsumoto 6d8c673efb array.c: replace recursive heapify with iterative implementation

Yukihiro "Matz" Matsumoto 05ad26f92a array: implement to_a and entries methods in c
Array#to_a now properly converts subclasses to Array objects. For example,
'class A<Array;end; p A.new(1,2).to_a.class' now returns Array, not A.

google-labs-jules[bot] 7f3329e393 Add descriptive comments for MRB_API functions in src/array.c
This change adds C-style multiline comments to all functions
marked with MRB_API in the src/array.c file.

The comments explain each function's purpose, its parameters,
and what it returns, where applicable. This improves the
readability and maintainability of the C API for mruby arrays.

The `@brief` markup was intentionally avoided as per your
requirements.

Yukihiro "Matz" Matsumoto 4b500eb971 Merge pull request #6340 from dearblue/array-cmp 2024-09-17 11:29:41 +09:00
dearblue 0955539cf9 Fix use-after-free in mrb_ary_delete()
`mrb_equal()` may call `obj.==` method internally.
Therefore, using an unupdated pointer and length after `mrb_equal()` could result in a read/write to an invalid address.

Fresh properties must always be obtained regardless of the result of `mrb_equal()`.
Also, `ary_modify()` must be called each time before writing.

ref. #6339

Yukihiro "Matz" Matsumoto 0972c84773 array.c (mrb_ary_delete): protect return value; fix #6339
The C local variable is not protected from GC, so we use the function
mrb_gc_protect() to keep the value. We also keep the arena position by
mrb_gc_arena_save(), then restoring the position for every new return
value, to minimize arena size.

Small cosmetic changes (pre-increment to post-increment) are also made
in this commit.

Yukihiro "Matz" Matsumoto 1f9fa06119 array.c: no need to assert if blk is a Proc; ref #6344
Since `blk` always comes from `mrb_get_args`, it should always be either
`nil` or a Proc.

leviongit 020cfa9283 prefer using mrb_yield to call block arguments 2024-09-04 20:44:51 +02:00
dearblue e476d9a344 Need to restore the GC arena after some function calls
When calling `mrb_equal()` or `mrb_funcall()` family functions, the GC arena should be restored if the loop is repeated by a non-immediate return value.

In my opinion, restoring the GC arena is unnecessary when a non-immediate (true) value causes the function to return (e.g. the `mrb_ary_index_m()` function).

The patch does not take into account the case of recursive calls and may be incomplete.

dearblue 29496c9931 Fix use-after-free for Array#<=>
The `mrb_ary_cmp()` function calls `mrb_cmp()` for comparison, but `mrb_cmp()` may call the `obj.<=>` method internally.
If a user-defined `<=>` method is called and the array object under comparison is expanded or reduced, a reference to an invalid address may subsequently be made.

Yukihiro "Matz" Matsumoto f35000f2a9 array.c (sort_cmp): comparing objects may be freed by GC; #6326
If comparing function (block or `<=>`) modifies the sorting array and GC
happens after the modification, objects passed to comparison may be
freed by GC.

but mruby avoid copying to reserve memory.

Yukihiro "Matz" Matsumoto 5bd63d6232 array.c: replace sort! method implementation
- use heap sort (O(1)) instead of merge sort (O(n)) for better space
  complexity.

- method implemented in C for better performance

As a result, simple sorting now consumes far less memory and is faster.
Since it's implemented in C, fiber context switching is not allowed from
comparison, but we consider the risk is minimal (no one switches context
in the comparison, right?)
