Conversation
- added comment that using "SSLv23" methods will automatically negotiate the highest possible TLS protocol version - cleaned up error handling in ACE_SSL_SOCK_Stream::close()
WalkthroughThe pull request introduces clarifying comments and minor code adjustments across SSL-related files. In the SSL context files, comments now explain that OpenSSL macros and enum values negotiate the highest available SSL/TLS version, including the addition of a new enum value (SSLv23). In the SSL socket stream source, the return value of the Changes

320-345: LGTM! Error handling improvements look good.The changes improve error handling by:
- Better organizing error cases
- Ensuring proper cleanup in all error scenarios
- Adding explicit handling for SSL-specific errors
Consider adding a comment explaining why
SSL_ERROR_SYSCALLis handled in the default case along withSSL_ERROR_SSL, as it might not be immediately obvious to future maintainers. For example:case SSL_ERROR_SSL: + // SSL_ERROR_SYSCALL needs the same error handling as SSL_ERROR_SSL case SSL_ERROR_SYSCALL: default:

161-161: LGTM! Explicit cast improves type safety.The explicit cast from
ssize_ttou_longmakes the conversion intention clear and prevents potential sign conversion warnings. The cast is safe here as error cases are properly handled earlier in the function.
