This commit changes io_fwrite to use rb_str_tmp_frozen_no_embed_acquire, which guarantees that the return string is not embedded. 
	Make io_fwrite safe for compaction

	[Bug #20169]

	Embedded strings are not safe for system calls without the GVL because
	compaction can cause pages to be locked causing the operation to fail
	with EFAULT. This commit changes io_fwrite to use rb_str_tmp_frozen_no_embed_acquire,
	which guarantees that the return string is not embedded.
Pin embedded shared strings 2023-12-01T20:04:31+00:00 Peter Zhu peter@peterzhu.ca 2023-11-30T19:47:09+00:00 80ea7fbad871b2222b16af1bd9f39e1f1828bbd4 Embedded shared strings cannot be moved because strings point into the slot of the shared string. There may be code using the RSTRING_PTR on the stack, which would pin the string but not pin the shared string, causing it to move. 
Embedded shared strings cannot be moved because strings point into the
slot of the shared string. There may be code using the RSTRING_PTR on
the stack, which would pin the string but not pin the shared string,

Use end of char boundary in start_with? 2023-09-01T23:23:28+00:00 John Hawthorn john@hawthorn.email 2023-08-31T22:12:47+00:00 d89b15cdce8a2fa36fc2a150551f0dd8e58814d7 Previously we used the next character following the found prefix to determine if the match ended on a broken character. This had caused surprising behaviour when a valid character was followed by a UTF-8 continuation byte. This commit changes the behaviour to instead look for the end of the last character in the prefix.

Previously we used the next character following the found prefix to
determine if the match ended on a broken character.

This had caused surprising behaviour when a valid character was followed
by a UTF-8 continuation byte.

This commit changes the behaviour to instead look for the end of the
last character in the prefix.

The ELTS_SHARED flag is generic, so we should prefer to use the flags
specific of the type (STR_SHARED for strings and RARRAY_SHARED_FLAG
for arrays).
