2022-12-02Introduce encoding check macroS-H-GAMELINKS
Notes: Merged: https://github.com/ruby/ruby/pull/6700
2022-11-24Make String#rstrip{,!} raise Encoding::CompatibilityError for broken coderangeJeremy Evans
It's questionable whether we want to allow rstrip to work for strings where the broken coderange occurs before the trailing whitespace and not after, but this approach is probably simpler, and I don't think users should expect string operations like rstrip to work on broken strings. In some cases, this changes rstrip to raise Encoding::CompatibilityError instead of ArgumentError. However, as the problem is related to an encoding issue in the receiver, and due not due to an issue with an argument, I think Encoding::CompatibilityError is the more appropriate error. Fixes [Bug #18931] Notes: Merged: https://github.com/ruby/ruby/pull/6282

2022-11-14Use string's capacity to determine if reembeddablePeter Zhu
During auto-compaction, using length to determine whether or not a string can be re-embedded may be a problem for newly created strings. This is because usually it requires a malloc before setting the length. If the malloc triggers compaction, then the string may be re-embedded and can cause crashes.
2022-11-03Make str_alloc_heap return a STR_NOEMBED stringPeter Zhu
This commit refactors str_alloc_heap to return a string with the STR_NOEMBED flag set. Notes: Merged: https://github.com/ruby/ruby/pull/6663
2022-10-04Correcting example for swapcase! methodVaevictusnet
Example, line 3, swapcase! was incorrect. implied that the swapcase! did /not/ change the starting string. Notes: Merged: https://github.com/ruby/ruby/pull/6474
2022-09-28Fix bug when slicing a string with broken encodingPeter Zhu
Commit aa2a428 introduced a bug where non-embedded string slices copied the encoding of the original string. If the original string had a broken encoding but the slice has valid encoding, then the slice would be incorrectly marked as broken encoding. Notes: Merged: https://github.com/ruby/ruby/pull/6456
2022-09-28Make string slices views rather than copiesPeter Zhu
Just like commit 1c16645 for arrays, this commit changes string slices to be a view rather than a copy even if it can be allocated through VWA. Notes: Merged: https://github.com/ruby/ruby/pull/6456
2022-09-26Refactor str_substr and str_subseqPeter Zhu
This commit extracts common code between str_substr and rb_str_subseq into a function called str_subseq. This commit also applies optimizations in commit 2e88bca to rb_str_subseq. Notes: Merged: https://github.com/ruby/ruby/pull/6447
2022-09-26string.c: don't create a frozen copy for str_new_sharedJean Boussier
str_new_shared already has all the necessary logic to do this and is also smart enough to skip this step if the source string is already a shared string itself. This saves a useless String allocation on each call. Notes: Merged: https://github.com/ruby/ruby/pull/6443
2022-09-26Fix coderange calculation in String#bKazuki Yamaguchi
Leave the new coderange unknown if the original encoding is not ASCII-compatible. Non-ASCII-compatible encoding strings with valid or broken coderange can end up as ascii-only. Fixes 9a8f6e392fbd ("Cheaply derive code range for String#b return value", 2022-07-25).
2022-09-23Revert "Revert "error.c: Let Exception#inspect inspect its message""Yusuke Endoh
This reverts commit b9f030954a8a1572032f3548b39c5b8ac35792ce. [Bug #18170]

UTF-16/UTF-32 * And simplify callers of get_actual_encoding(). * See [Feature #18949]. * See https://github.com/ruby/ruby/pull/6322#issuecomment-1242758474
2022-09-09Avoid unnecessary copying when removing the leading part of a stringKazuki Yamaguchi
Remove the superfluous str_modify_keep_cr() call from rb_str_update(). It ends up calling either rb_str_drop_bytes() or rb_str_splice_0(), which already does checks if necessary. The extra call makes the string "independent". This is not always wanted, in other words, it can keep the same shared root when merely removing the leading part of a shared string.

2022-08-18rb_str_resize: Only clear coderange on truncationJean Boussier
If we are expanding the string or only stripping extra capacity then coderange won't change, so clearing it is wasteful. Notes: Merged: https://github.com/ruby/ruby/pull/6178
2022-08-11Fix inspect for unicode codepoint 0x85Jeremy Evans
This is an inelegant hack, by manually checking for this specific code point in rb_str_inspect. Some testing indicates that this is the only code point affected. It's possible a better fix would be inside of lower-level encoding code, such that rb_enc_isprint would return false and not true for codepoint 0x85.

2022-07-26Cheaply derive code range for String#b return valueKevin Menard
The result of String#b is a string with an ASCII_8BIT/BINARY encoding. That encoding is ASCII-compatible and has no byte sequences that are invalid for the encoding. If we know the receiver's code range, we can derive the resulting string's code range without needing to perform a full code range scan.

2022-07-25rb_str_buf_append: add a fast path for ENC_CODERANGE_VALIDJean Boussier
If the RHS has valid encoding, and both strings have the same encoding, we can use the fast path.

2022-07-21Make String#each_line work correctly with paragraph separator and chompJeremy Evans
Previously, it was including one newline when chomp was used, which is inconsistent with IO#each_line behavior. This makes behavior consistent with IO#each_line, chomping all paragraph separators (multiple consecutive newlines), but not single newlines.
