This commit adds documentation for the immutable option in the expires_in method in the ConditionalGet module of Action Pack. The immutable option, when set to true, adds the immutable directive to the Cache-Control header. This directive indicates that the response body will not change over time, making it suitable for long-term caching.

The documentation also mentions that any additional key-value pairs provided will be concatenated as directives in the Cache-Control header. This update provides clarity on how to use the immutable option and its implications for caching responses in Rails applications.

This commit optimizes the to_hash method in the HashWithIndifferentAccess class by avoiding the inefficient process of creating a copy by starting from an empty hash and inserting keys one by one. Instead, the new approach directly converts the hash to an array and transforms the values, saving on unnecessary reallocations and re-hashing of keys. Additionally, a dedicated method is defined to convert values to hashes, eliminating the need for generic convert_value checks.

The commit includes benchmark tests comparing the original method with the optimized versions (KwstannardHWIA and ByrootHWIA). The results show that the optimized versions are significantly faster, with the ByrootHWIA implementation outperforming the others in terms of speed, especially for larger hashes. Overall, these changes improve the efficiency of converting HashWithIndifferentAccess objects to regular hashes, enhancing performance in scenarios with varying hash sizes and deep nesting levels.

This commit fixes a deadlock issue in the ConnectionPool#checkout method. The issue was causing a deadlock when multiple threads were trying to access the connection pool simultaneously. The fix involves implementing a new locking mechanism to prevent multiple threads from accessing the connection pool at the same time, thus resolving the deadlock issue. This ensures that threads can safely check out connections from the pool without causing a deadlock.

Overall, this commit addresses a critical issue in the connection pool functionality by implementing a new locking mechanism to prevent deadlocks. This fix ensures that multiple threads can safely access the connection pool without causing conflicts, improving the reliability and efficiency of the connection pool functionality.
