2023-09-09memory_view: Avoid using bit fieldSutou Kouhei
Bit field's memory layout is implementation-defined. See also: https://wiki.sei.cmu.edu/confluence/display/c/EXP11-C.+Do+not+make+assumptions+regarding+the+layout+of+structures+with+bit-fields If memory layout is implementation-defined, it's difficult to use from FFI library such as Ruby-FFI.

2023-07-27Resurrect rb_reg_prepare_re C APITakashi Kokubun
Existing strscan releases rely on this C API. It means that the current Ruby master doesn't work if your Gemfile.lock has strscan unless it's locked to 3.0.7, which is not released yet. To fix it, let's not remove the C API we've exposed to users.
2023-07-27Add function rb_reg_onig_matchPeter Zhu
rb_reg_onig_match performs preparation, error handling, and cleanup for matching a regex against a string. This reduces repetitive code and removes the need for StringScanner to access internal data of regex. Notes: Merged: https://github.com/ruby/ruby/pull/8123

Since edf01d4e82d8e44ee30ec41fbcb7f802bc8b8c5d, fake string treats NULL as an empty string.

2023-07-13Store object age in a bitmapMatt Valentine-House
Closes [Feature #19729] Previously 2 bits of the flags on each RVALUE are reserved to store the number of GC cycles that each object has survived. This commit introduces a new bit array on the heap page, called age_bits, to store that information instead. This patch still reserves one of the age bits in the flags (the old FL_PROMOTED0 bit, now renamed FL_PROMOTED). This is set to 0 for young objects and 1 for old objects, and is used as a performance optimisation for the write barrier. Fetching the age_bits from the heap page and doing the required math to calculate if the object was old or not would slow down the write barrier. So we keep this bit synced in the flags for fast access. Notes: Merged: https://github.com/ruby/ruby/pull/7938

2023-06-29Fix memory leak when copying ST tablesPeter Zhu
st_copy allocates a st_table, which is not needed for hashes since it is allocated by VWA and embedded, so this causes a memory leak. The following script demonstrates the issue: ```ruby 20.times do 100_000.times do {a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7, h: 8, i: 9} end puts `ps -o rss= -p #{$$}` end ``` Notes: Merged: https://github.com/ruby/ruby/pull/8000

2023-06-12[DOC] Should use `NULL` instead of zeroNobuyoshi Nakada
Since no type information is available for variadic arguments, 0 is passed as `int` without promoting to pointer. On platforms where `sizeof(int) < sizeof(void*)`, the terminator argument may be read together with an adjoining word, and may not be found.

This reverts commit 18e55fc1e1ec20e8f3166e3059e76c885fc9f8f2. fix [Bug #19704] https://bugs.ruby-lang.org/issues/19704 This breaks compatibility for extension libraries. Such changes need a discussion.
2023-05-30Hide most of the implementation of `struct rb_io`. (#6511)Samuel Williams
* Add rb_io_path and rb_io_open_descriptor. * Use rb_io_open_descriptor to create PTY objects * Rename FMODE_PREP -> FMODE_EXTERNAL and expose it FMODE_PREP I believe refers to the concept of a "pre-prepared" file, but FMODE_EXTERNAL is clearer about what the file descriptor represents and aligns with language in the IO::Buffer module. * Ensure that rb_io_open_descriptor closes the FD if it fails If FMODE_EXTERNAL is not set, then it's guaranteed that Ruby will be responsible for closing your file, eventually, if you pass it to rb_io_open_descriptor, even if it raises an exception. * Rename IS_EXTERNAL_FD -> RUBY_IO_EXTERNAL_P * Expose `rb_io_closed_p`. * Add `rb_io_mode` to get IO mode. --------- Co-authored-by: KJ Tsanaktsidis <ktsanaktsidis@zendesk.com> Notes: Merged-By: ioquatix <samuel@codeotaku.com>

2023-05-26Move rb_thread_cond_struct definition into thread_native.hKJ Tsanaktsidis
On Win32, currently, rb_nativethread_cond_t is an incomplete type because it's a typedef for `struct rb_thread_cond_struct`. That means you can't actually allocate a rb_nativethread_cond_t unless you also include THREAD_IMPL_H (since its defined in thread_win32.h) (alternatively, including vm_core.h also works). Move the definition of rb_thread_cond_struct into thread_native.h to alleviate this. Notes: Merged: https://github.com/ruby/ruby/pull/7865

2023-04-14Add RB_WARN_CATEGORY_DEFAULT_BITSJean Boussier
Followup: ac123f167a364c3d7a43eca78d564e41f6dbb91e RB_WARN_CATEGORY_ALL_BITS is exposed in a public header, so it makes sense for it to be updated to contain all valid bits. Instead we introduce RB_WARN_CATEGORY_DEFAULT_BITS to list the categories that are enabled by default. Notes: Merged: https://github.com/ruby/ruby/pull/7710

2023-04-04[Feature #19579] Remove !USE_RVARGC code (#7655)Peter Zhu
Remove !USE_RVARGC code [Feature #19579] The Variable Width Allocation feature was turned on by default in Ruby 3.2. Since then, we haven't received bug reports or backports to the non-Variable Width Allocation code paths, so we assume that nobody is using it. We also don't plan on maintaining the non-Variable Width Allocation code, so we are going to remove it. Notes: Merged-By: maximecb <maximecb@ruby-lang.org>

2023-03-17[Feature #19406] Allow declarative definition of referencesMatt Valentine-House
When using rb_data_type_struct to wrap a C struct, that C struct can contain VALUE references to other Ruby objects. If this is the case then one must also define dmark and optionally dcompact callbacks in order to allow these objects to be correctly handled by the GC. This is suboptimal as it requires GC related logic to be implemented by extension developers. This can be a cause of subtle bugs when references are not marked of updated correctly inside these callbacks. This commit provides an alternative approach, useful in the simple case where the C struct contains VALUE members (ie. there isn't any conditional logic, or data structure manipulation required to traverse these references). In this case references can be defined using a declarative syntax as a list of edges (or, pointers to references). A flag can be set on the rb_data_type_struct to notify the GC that declarative references are being used, and a list of those references can be assigned to the dmark pointer instead of a function callback, on the rb_data_type_struct. Macros are also provided for simple declaration of the reference list, and building edges. To avoid having to also find space in the struct to define a length for the references list, I've chosed to always terminate the references list with RUBY_REF_END - defined as UINTPTR_MAX. My assumption is that no single struct will ever be large enough that UINTPTR_MAX is actually a valid reference. Notes: Merged: https://github.com/ruby/ruby/pull/7153
