     [ https://issues.apache.org/jira/browse/THRIFT-96?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexander Shigin updated THRIFT-96:
-----------------------------------

    Attachment: thrift-peek-fix.patch

http://git.thrift-rpc.org/?p=thrift.git;a=shortlog;h=refs/heads/pri/shigin/peek

There is two changes:
  * create new TUnderlyingTransport to share common code with TBufferedTransport and TFramedTransport. The change need because TBufferedTransport doesn't call peek of underlying transport.
  * fix TSocket.peek for freebsd.

> POSIX says what recv(2) should returns 0 if peer has performed a shutdown. This feature uses in TBufferedTransport 
> {code}
>   bool peek() {
>     if (rBase_ == rBound_) {
>       setReadBuffer(rBuf_.get(), transport_->read(rBuf_.get(), rBufSize_));
>     }
>     return (rBound_ > rBase_);
>   }
> {code}
> The decision works fine on linux, but fails on freebsd. In freebsd, recv returns -1 and errno==ECONNRESET.
