> THttpClient sends previous message or partial message after http error

> Key: THRIFT-5324
> URL: https://issues.apache.org/jira/browse/THRIFT-5324
> Project: Thrift
> Issue Type: Bug
> Components: Go - Library
> Affects Versions: 0.13.0
> Reporter: Ilya Morozov
> Priority: Major
> Fix For: 0.14.0
>
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> We noticed that there's an "out of order sequence response" error immediately
> after an http error or premature context closure. We are seeing a lot of
> these in production.
> It seems like THttpClient does not reset it's internal buffer when http
> client returns an error, leaving the whole or partially read message in the
> buffer. On next call THttpClient sends the remains of previous message
> followed by current message, causing the server to execute it and return the
> previous seqId hence the "out of order sequence response" errors.
> Here's a small test of THttpClient that demonstrates this issue:
> [https://github.com/wheely/thrift/blob/c130f2452428540a4eefc4c422c8abc329ec837d/lib/go/thrift/http_client_test.go#L101-L147]
> .
> First flush fails due to closed context, second flush succeeds but writes
> both messages to the server. In current thrift version this test fails with:
> {code:java}
> http_client_test.go:144: Received unexpected data: write 1write 2{code}
>
> Please let me know if you need a better example.
