Ported Ruby extension to upb_msg (#8184) * WIP. * WIP. * WIP. * WIP. * WIP. * WIP. * Added some missing files. * WIP. * WIP. * Updated upb. * Extension loads, but crashes immediately. * Gets through the test suite without SEGV! Still a lot of bugs to fix, but it is a major step! 214 tests, 378 assertions, 37 failures, 147 errors, 0 pendings, 0 omissions, 0 notifications 14.0187% passed * Test and build for Ruby 3.0 * Fixed a few more bugs, efficient #inspect is almost done. 214 tests, 134243 assertions, 30 failures, 144 errors, 0 pendings, 0 omissions, 0 notifications 18.6916% passed * Fixed message hash initialization and encode depth checking. 214 tests, 124651 assertions, 53 failures, 70 errors, 0 pendings, 0 omissions, 0 notifications 42.5234% passed * A bunch of fixes to failing tests, now 70% passing. 214 tests, 202091 assertions, 41 failures, 23 errors, 0 pendings, 0 omissions, 0 notifications 70.0935% passed * More than 80% of tests are passing now. 214 tests, 322331 assertions, 30 failures, 9 errors, 0 pendings, 0 omissions, 0 notifications 81.7757% passed Unfortunately there is also a sporadic bug/segfault hanging around that appears to be GC-related. * Add linux/ruby30 and macos/ruby30 * Use rvm master for 3.0.0-preview2 * Over 90% of tests are passing! 214 tests, 349898 assertions, 15 failures, 1 errors, 0 pendings, 0 omissions, 0 notifications 92.5234% passed * Passes all tests! 214 tests, 369388 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications 100% passed * A bunch of cleanup. 1. Removed a bunch of internal-only symbols from headers. 2. Required a frozen check to get a non-const pointer to a map or array. 3. De-duplicated the code to get a type argument for Map/RepeatedField. * Removed a bunch more stuff from protobuf.h. There is an intermittent assert failure. Intermittent failure: ruby: ../../../../ext/google/protobuf_c/protobuf.c:263: ObjectCache_Add: Assertion `rb_funcall(obj_cache2, (__builtin_constant_p("[]") ? __extension__ ({ static ID rb_intern_id_cache; if (!rb_intern_id_cache) rb_intern_id_cache = rb_intern2((("[]") ), (long)strlen(("[]"))); (ID) rb_intern_id_cache; }) : rb_intern("[]")), 1, key_rb) == val' failed * Removed a few more things from protobuf.h. * Ruby 3.0.0-preview2 to 3.0.0 * Require rake-compiler-dock >= 1.1.0 * More progress, fighting with the object cache. * Passes on all Ruby versions! * Updated and clarified comment regarding WeakMap. * Fixed the wyhash compile. * Fixed conformance tests for Ruby. Conformance results now look like: RUBYLIB=../ruby/lib:. ./conformance-test-runner --enforce_recommended --failure_list failure_list_ruby.txt --text_format_failure_list text_format_failure_list_ruby.txt ./conformance_ruby.rb CONFORMANCE TEST BEGIN ==================================== CONFORMANCE SUITE PASSED: 1955 successes, 0 skipped, 58 expected failures, 0 unexpected failures. CONFORMANCE TEST BEGIN ==================================== CONFORMANCE SUITE PASSED: 0 successes, 111 skipped, 8 expected failures, 0 unexpected failures. Fixes include: - Changed Ruby compiler to no longer reject proto2 maps. - Changed Ruby compiler to emit a warning when proto2 extensions are present instead of rejecting the .proto file completely. - Fixed conformance tests to allow proto2 and look up message by name instead of hardcoding a specific list of messages. - Fixed conformance test to support the "ignore unknown" option for JSON. - Fixed conformance test to properly report serialization errors. * Removed debug printf and fixed #inspect for floats. * Fixed compatibility test to have proper semantics for #to_json. * Updated Makefile.am with new file list. * Don't try to copy wyhash when inside Docker. * Fixed bug where we would forget that a sub-object is frozen in Ruby >=2.7. * Avoid exporting unneeded symbols and refactored a bit of code. * Some more refactoring. * Simplified and added more comments. * Some more comments and simplification. Added a missing license block. Co-authored-by: Masaki Hara <hara@wantedly.com>
