2021-11-26Improve performance of embedded string allocationPeter Zhu
Non-VWA embedded string allocation had a performance regression. This commit improves performance of non-VWA embedded string allocation. Notes: Merged: https://github.com/ruby/ruby/pull/5183
2021-11-23Speed up Ractors for Variable Width AllocationPeter Zhu
This commit adds a Ractor cache for every size pool. Previously, all VWA allocated objects used the slowpath and locked the VM. On a micro-benchmark that benchmarks String allocation: VWA turned off: 29.196591 0.889709 30.086300 ( 9.434059) VWA before this commit: 29.279486 41.477869 70.757355 ( 12.527379) VWA after this commit: 16.782903 0.557117 17.340020 ( 4.255603) Notes: Merged: https://github.com/ruby/ruby/pull/5151
2021-11-08[Feature #18290] Remove all usages of rb_gc_force_recyclePeter Zhu
This commit removes usages of rb_gc_force_recycle since it is a burden to maintain and makes changes to the GC difficult. Notes: Merged: https://github.com/ruby/ruby/pull/4363

2021-10-25[Feature #18239] Implement VWA for stringsPeter Zhu
This commit adds support for embedded strings with variable capacity and uses Variable Width Allocation to allocate strings. Notes: Merged: https://github.com/ruby/ruby/pull/4933

Notes: Merged: https://github.com/ruby/ruby/pull/4933
2021-10-15Update documentation for String and Symbol to discuss differencesJeremy Evans
Implements [Feature #14347]
2021-10-08Add tests for the edge caces of `String#end_with?`Nobuyoshi Nakada
Also, check if a suffix is empty, to guarantee the assumption of `onigenc_get_left_adjust_char_head` that `*s` is always accessible, even in the case of `SHARABLE_MIDDLE_SUBSTRING`.
2021-10-06* remove trailing spaces. [ci skip]git
2021-10-05Fix documentation for String#{<<,concat,prepend}Jeremy Evans
These methods mutate and return the receiver, they don't create and return a new string. Fixes [Bug #18241]
2021-10-05Adjust types to rb_enc_left_char_headNobuyoshi Nakada
I dislike unnatural casts.
2021-10-05Remove a redundant cast between the exact same typesNobuyoshi Nakada
2021-10-05rb_enc_left_char_head(): take void*卜部昌平
Nobu doesn't like (char*) cast. Notes: Merged: https://github.com/ruby/ruby/pull/4909
2021-10-05downcase_single/upcase_single: assume ASCII卜部昌平
These functions assume ASCII compatibility. That has to be ensured in their caller. Notes: Merged: https://github.com/ruby/ruby/pull/4909
2021-10-05include/ruby/encoding.h: convert macros into inline functions卜部昌平
Less macros == huge win. Notes: Merged: https://github.com/ruby/ruby/pull/4909

Why did they even exist? Notes: Merged: https://github.com/ruby/ruby/pull/4909

2021-09-11Remove printf family from the mjit headerNobuyoshi Nakada
Linking printf family functions makes mjit objects to link unnecessary code. Notes: Merged: https://github.com/ruby/ruby/pull/4820

2021-09-08[Bug #18154] Fix memory leak in String#initializePeter Zhu
String#initialize can leak memory when called on a string that is marked with STR_NOFREE because it does not unset the STR_NOFREE flag. Notes: Merged: https://github.com/ruby/ruby/pull/4814
2021-08-17Treat NULL fake string as an empty stringNobuyoshi Nakada
And the NULL string must be of size 0.
2021-08-11Term fill in String#{,l,r}strip! even when SHARABLE_MIDDLE_SUBSTRINGJeremy Evans
Each of these methods calls str_modify_keep_cr before term filling, which should ensure the backing string uses private memory, and therefore term filling should not affect other strings. Skipping the term filling was added in a707ab4bc8a29241440f56696098efa2f7f3ff45. Fixes [Bug #12540] Notes: Merged: https://github.com/ruby/ruby/pull/4731
2021-08-03Fix indentation in string.cPeter Zhu
7 spaces were used for 2 levels of indentation. This commit changes it to use 8 spaces. Notes: Merged: https://github.com/ruby/ruby/pull/4706

2021-06-23Add Related link from String#hash to Object#hashKetan Bhatt
We came across a bug in our code because we assumed `String#hash` to be consistent across Ruby processes, which was incorrect. Our search lead us to `Object#hash` which has the right warning that `String#hash` doesn't. We also noticed that a previous version of the documentation for `String#hash` pointed to `Object#hash` that was removed by https://github.com/ruby/ruby/pull/3565. We think this removal might not be intended and just got missed amidst other changes. Notes: Merged: https://github.com/ruby/ruby/pull/4498

2021-03-22rb_enc_interned_str: handle autoloaded encodingsJean Boussier
If called with an autoloaded encoding that was not yet initialized, `rb_enc_interned_str` would crash with a NULL pointer exception. See: https://github.com/ruby/ruby/pull/4119#issuecomment-800189841 Notes: Merged: https://github.com/ruby/ruby/pull/4290
2021-02-20Make String#{strip,lstrip}{,!} strip leading NUL bytesJeremy Evans
The documentation already specifies that they strip whitespace and defines whitespace to include null. This wraps the new behavior in the appropriate guards in the specs, but does not specify behavior for previous versions, because this is a bug that could be backported.
