Subject [jira] [Commented] (THRIFT-1690) Sockets and Pipe Handles truncated on Win64
Date Tue, 13 Nov 2012 19:34:12 GMT

Peace C commented on THRIFT-1690:
---------------------------------

The fixes are very much appreciated. We're not building 64-bit yet but when the time comes
this will be beneficial.

A consequence of the restructuring (wrapping the Pipe classes with #ifdef _WIN32 and typedef'ing
the name for *NIX) is that it's more difficult to implement anonymous pipes for *NIX. It'll
be alot of duplicated code since all the Pipe related methods will need to be replicated for
*NIX. It also makes the calling code less platform-agnostic. With these changes, the calling
code can't be cross-platform for Windows & *NIX because, for example, setPipename doesn't
exist in TServerSocket. You've just moved the burden of the #ifdefs from the abstract Pipe
class to the calling code. That was the motivation for casting HANDLE to int and vice-versa.
Perhaps we could cast between IntPtr instead?

>         Environment: 64-bit Windows

> On 64-bit Windows, "int" is a 32-bit value.  SOCKET and HANDLE are 64-bit.
> All of the files dealing with sockets in thrift use "int" as the type of a socket, as
this is the idiomatic way to handle sockets on POSIX systems.  For portability, a SOCKET typedef
is probably needed.
> For the Pipe Server and Pipe Transport, HANDLEs are cast to ints to store as member variables
for some reason (maybe to avoid #including <windows.h> in a header?).
> Both of these situations can result in invalid handles being used (and valid handles
being leaked) when the system is under load.
