the problem of using ByteSeq in slice(ice3.6.1 and visual studio 2013)

fengshengheli

I write a slice. The part of slice file below:
module Demo
{
sequence<byte> ByteSeq;

interface FileService
{
ByteSeq fileRead(string fileName, int initialPosition, out bool endOfFile);
};
};

It can generate .h and .cpp file. The server and client program complie well. But when call fileRead function, the service side code error.

::Ice::DispatchStatus
Demo::FileService::___fileRead(::IceInternal::Incoming& __inS, const ::Ice::Current& __current)
{
__checkMode(::Ice::Normal, __current.mode);
::IceInternal::BasicStream* __is = __inS.startReadParams();
::std::string __p_fileName;
::Ice::Int __p_initialPosition;
__is->read(__p_fileName);
__is->read(__p_initialPosition);
__inS.endReadParams();
bool __p_endOfFile;
::Demo::ByteSeq __ret = fileRead(__p_fileName, __p_initialPosition, __p_endOfFile, __current);
::IceInternal::BasicStream* __os = __inS.__startWriteParams(::Ice::DefaultFormat);
__os->write(__p_endOfFile);
__os->write(__ret);
__inS.__endWriteParams(true);
return ::Ice::DispatchOK;
}

::Demo::ByteSeq __ret = fileRead(__p_fileName, __p_initialPosition, __p_endOfFile, __current); call failed.
The error message "0x00407247 处有未经处理的异常(在 TestServer.exe 中): 0xC00000FD: Stack overflow (参数: 0x00000000, 0x01812000)。".

If i do not use ByteSeq in fileRead, it works ok.

It works using Ice3.4.1 with visual studio 2008.
But failed using Ice3.6.1 with visual studio 2013.

xdm

can you provide a complete sample program that allow us to reproduce the issue?

​The project files size is 20M. I can not upload to the web. Can you give me your email?

xdm

We do not need the binaries, upload just the project file and the sources that will allow us to build it.

fengshengheli

I only upload the source files.

xdm

Can you also post the complete stacktrace for the failure, looking at your code it is not clear this is related to Ice code.

When client call fileRead interface. The server code running to file file_service.cpp ___fileRead function.
Attachment not found.

I click F11 , running to the code file_service_i.cpp fileRead function.
Attachment not found.


I click F10 or F11, can not run to "endOfFile = false;".
But error occured.

Attachment not found.

Other interface works ok. and if I change fileRead slice, don't use ByteSeq as return value or as out parameter, it work ok.
So I guess the reason is ByteSeq using.

xdm

const Poco::Int32 maxReadBytes = 1024 * 1024;
Ice::Byte buffer[maxReadBytes];

This code might be problematic, as it allocates 1MB on the stack, which is the maximum if you are using the default compiler settings, see https://msdn.microsoft.com/en-us/library/tdkhxaks.aspx?f=255&MSPPError=-2147217396

It works ok after the code changed..
const Poco::Int32 maxReadBytes = 1024*1000;

or after modify the value of
/STACK:reserve
Thank you very much!
