Henrique Mendonca commented on THRIFT-1973: ------------------------------------------- Hi Eric, Thanks for you patch. Are both your client and server running C#? Would you be able to provide us some unit-testing to reproduce that? We are already using this on production code and the cases you mentioned were successfully tested against a c++ server, but yes, this could be a problem on the other side. Ideally, we should make the existing tests to optionally use compact binary to check this.

Purpose to change longToZigzag from > (ulong)(((ulong)n << 1) ^ ((ulong)n >> 63)) to (ulong)(n << 1) ^ (ulong)(n >> > 63). > Will need to do same for intToZigZag. The reason is that we want arithmetic > shift not logic shift. > The test case in the project shows this, the output on server and client are > different even though client received the same number back. -- This message is automatically generated by JIRA.
