---------------------------------------
Issue Type: Improvement (was: Test)
> Proper use of sequence IDs in all clients and servers
> -----------------------------------------------------
>
> Key: THRIFT-4405
> URL: https://issues.apache.org/jira/browse/THRIFT-4405
> Project: Thrift
> Issue Type: Improvement
> Components: Test Suite
> Affects Versions: 0.10.0
> Environment: docker ubuntu-xenial
> Reporter: James E. King, III
> Assignee: James E. King, III
>
> Create a feature test that verifies sequence numbers are used properly.
> Write a server that verifies clients are generating unique sequence IDs.
> Write a client that makes sure servers return the same sequence ID that was
> given.
> To do this, I enhanced the C++ TProcessorEventHandler class to include a
> preReadSeq, which is like preRead but carries the sequence ID.
> In the C++ TestServer, I check to see if the sequence numbers are unique and
> do not repeat; if any of them do, the cpp test fails.
> The following languages properly send sequence IDs (for the binary protocol):
> * dart
> * go
> * nodejs
> * java
> * rs
> The rest of the languages do not. Now, one could argue that unless a
> language has a concurrent-safe client and server, sequence IDs are
> unnecessary. While that is true, all languages should respect that the
> protocol has a sequence ID and there could be future implementations that
> will require all clients are well-behaved, which is why I am putting this
> test in.
> Languages fixed up so unique sequence IDs are sent by the client, and
> verified by the tests:
> * cpp (was only sending unique sequence IDs for Concurrent clients, now it
> does for the regular one too)
> * csharp (seqid_ was not bring incremented with each use)
> * lua (seqid_ was not bring incremented with each use)
> * perl (seqid_ was not bring incremented with each use)
> * ruby (seqid_ was not bring incremented with each use and a unit test was
> updated to no longer be pending)
> Languages left to do:
> * c_glib
> * erlang
> * haskell
> * php
> * python
> * python3
> * any non-cross tested languages
