Subject: [jira] [Created] (ARROW-822) [Python] StreamWriter fails to open with socket as sink MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit X-JIRA-FingerPrint: 30527f35849b9dde25b450d4833f0394 archived-at: Fri, 14 Apr 2017 17:05:46 -0000 Bryan Cutler created ARROW-822: ---------------------------------- Summary: [Python] StreamWriter fails to open with socket as sink Key: ARROW-822 URL: https://issues.apache.org/jira/browse/ARROW-822 Project: Apache Arrow Issue Type: Bug Reporter: Bryan Cutler Trying to use pyarrow StreamWriter to write to a socket fails. I've tried the following: - Use socket directly and get "TypeError: Unable to read from object of type: " looks like pyarrow expects the object to have a "write" attribute - Using as a file object with: "sock.makefile("wb", 65536)" get the error "pyarrow.error.ArrowIOError: IOError: '_fileobject' object has no attribute 'tell'" Not sure why exactly "tell" is required. - using "os.fdopen(sock.fileno(), "wb", 65536)" get a rather cryptic error that I've been unable to track down: "terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid" Seems to indicate some kind of std::string construction with a NULL, but I can't find that anywhere -- This message was sent by Atlassian JIRA (v6.3.15#6346)
