James E. King III commented on THRIFT-4646: ------------------------------------------- Would you consider this to be part of THRIFT-4599? > Effective Dart and Exceptions > ----------------------------- > > Key: THRIFT-4646 > URL: https://issues.apache.org/jira/browse/THRIFT-4646 > Project: Thrift > Issue Type: Bug > Components: Dart - Compiler > Reporter: Dave Walker > Priority: Trivial > > Thrift implemented dart output ~3 years ago and in doing so outputs > exceptions in classes that extend Error[1]. At the time this commit[2] was > done this was acceptable. However, a year or so after this commit Effective > Dart introduced a rule that you "DON'T" catch Errors or anything that > implements them[3]. However, Dart SDK had for the Error type ~5 years ago > that they should not be used for expect or catch[4]. > As such this ticket requests that the generator for dart code should have > exception types implement Exception rather than extending Error. Although > Error and Exception are used pretty interchangeably in terms of throwing, > they do differ for the expect/catch and as such would warrant being included > in a major version change. > [1] - > [https://github.com/apache/thrift/blob/master/compiler/cpp/src/thrift/generate/t_dart_generator.cc#L781] > [2] - > [https://github.com/apache/thrift/commit/932c4700c6e3aee20b74d5e2f562326029e6b9c8] > [3] - > [https://www.dartlang.org/guides/language/effective-dart/usage#dont-explicitly-catch-error-or-types-that-implement-it] > [4] - > [https://github.com/dart-lang/sdk/commit/460e157416212a0ce90dbfbc6e2e2f68c4e421e8] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
