Some .proto files contain complex syntax that does not be described in protobuf official site (https://developers.google.com/protocol-buffers/docs/reference/proto3-spec). 1. Update 'epan/protobuf_lang_parser.lemon' to: 1) Support complex option names format (EBNF): optionName = ( ident | "(" fullIdent ")" ) { "." ( ident | "(" fullIdent ")" ) } for example, "option (complex_opt2).(grault) = 654;". 2) Make enum body support 'reserved' section (EBNF): enumBody = "{" { reserved | option | enumField | emptyStatement } "}" 3) Allow the value of field or enumValue option to be "{ ... }" other than constant: enumValueOption = optionName "=" ( constant | customOptionValue ) ";" fieldOption = optionName "=" ( constant | customOptionValue ) ";" 4) Allow 'group' section missing 'label' (for example, in 'oneof' section). 5) Make 'oneof' section support 'option' and 'group' sections (BNF): oneof = "oneof" oneofName "{" { oneofField | option | group | emptyStatement } "}" 6) Ignore unused 'extend' section. 7) Fix the bug of one string being splitted into multi-lines. 2. Update 'epan/protobuf_lang_tree.c' to: 8) Fix the bug of parsing repeated option. 3. Update 'test/suite_dissection.py' to add test case for parsing complex syntax .proto files: test/protobuf_lang_files/complex_proto_files/unittest_custom_options.proto test/protobuf_lang_files/complex_proto_files/complex_syntax.proto and dependency files: test/protobuf_lang_files/well_know_types/google/protobuf/any.proto test/protobuf_lang_files/well_know_types/google/protobuf/descriptor.proto Refer to issue #17046 |
