[jira] [Created] (THRIFT-5188) Occasional ERROR_INSUFFICIENT_BUFFER at WinHttpQueryHeaders()

Jens Geyer created THRIFT-5188:
----------------------------------

             Summary: Occasional ERROR_INSUFFICIENT_BUFFER at WinHttpQueryHeaders()
                 Key: THRIFT-5188
                 URL: https://issues.apache.org/jira/browse/THRIFT-5188
             Project: Thrift
          Issue Type: Bug
          Components: Delphi - Library
            Reporter: Jens Geyer


Since {{WinHttpQueryHeaders()}} sometimes returns error 122 (ERROR_INSUFFICIENT_BUFFER) even if the buffer is large enough. According to the docs, WINHTTP_QUERY_FLAG_NUMBER always returns a 32 bit number (which it indeed does), but for some strange reason since win 10 build 18636.815 passing a DWORD sized buffer is sometimes not enough anymore
