o Code simplification and refactoring: - Eliminate some uses of lower-level control reply abstractions, primarily in the onion_helper functions. Closes ticket 30889. - Extract our variable manipulation code from confparse.c to a new lower-level typedvar.h module. Closes ticket 30864. - - Improve documentation in circuit padding subsystem. Patch by Tobias - Pulls. Closes ticket 31113. - - Lower another layer of object management from confparse.c to - a more general tool. Now typed structure members are accessible - via an abstract type. Implements ticket 30914. + - Improve documentation in circuit padding subsystem. Patch by + Tobias Pulls.

Implements ticket 30914. - Move our backend logic for working with configuration and state files into a lower-level library, since in no longer depends on any tor-specific functionality. Closes ticket 31626. - - Numerous simplifications in configuration-handling logic: - remove duplicated macro definitions, replace magical names - with flags, and refactor "TestingTorNetwork" to use the - same default-option logic as the rest of Tor. - Closes ticket 30935. + - Numerous simplifications in configuration-handling logic: remove + duplicated macro definitions, replace magical names with flags, + and refactor "TestingTorNetwork" to use the same default-option + logic as the rest of Tor. Closes ticket 30935. - Replace our ad-hoc set of flags for configuration variables and configuration variable types with fine-grained orthogonal flags corresponding to the actual behavior we want. Closes ticket 31625. - Rework bootstrap tracking to use the new publish-subscribe subsystem. Closes ticket 29976. - - Rewrite format_node_description() and router_get_verbose_nickname() to - use strlcpy() and strlcat(). The previous implementation used memcpy() - and pointer arithmetic, which was error-prone. - Closes ticket 31545. This is CID 1452819. - - Split extrainfo_dump_to_string() into smaller functions. - Closes ticket 30956. - - Use the ptrdiff_t type consistently for expressing variable offsets and - pointer differences. Previously we incorrectly (but harmlessly) used - int and sometimes off_t for these cases.

o Documentation: - Include an example usage for IPv6 ORPort in our sample torrc. Closes ticket 31320; patch from Ali Raheem. - - Use RFC 2397 data URL scheme to embed image into tor-exit-notice.html - so that operators would no longer have to host it themselves. - Closes ticket 31089. - - o New system requirements (build system): - - Do not include the deprecated <sys/sysctl.h> on Linux or Windows system. - Closes 31673; + - Use RFC 2397 data URL scheme to embed image into tor-exit- + notice.html so that operators would no longer have to host it + themselves.
