Hi,
After it was suggested that set cannot be used in php, I changed from php to
python. Even in python, am facing the same issue (I think).
Traceback (most recent call last):
File "depository.py", line 52, in <module>
responses = client.findValue(request)
File "/home/shraddha/dev/python/packages/mvr/MyServer.py", line 40, in
findValue
return self.recv_findValue()
File "/home/shraddha/dev/python/packages/mvr/MyServer.py", line 58, in
recv_findValue
result.read(self._iprot)
File "/home/shraddha/dev/python/packages/mvr/MyServer.py", line 194, in
read
self.success.add(_elem21)
TypeError: unhashable instance
Below is the python thrift code generated.
def read(self, iprot):
if iprot.__class__ == TBinaryProtocol.TBinaryProtocolAccelerated and
isinstance(iprot.trans, TTransport.CReadableTransport) and self.thrift_spec
is not None and fastbinary is not None:
fastbinary.decode_binary(self, iprot.trans, (self.__class__,
self.thrift_spec))
return
iprot.readStructBegin()
while True:
(fname, ftype, fid) = iprot.readFieldBegin()
if ftype == TType.STOP:
break
if fid == 0:
if ftype == TType.SET:
self.success = set()
(_etype19, _size16) = iprot.readSetBegin()
for _i20 in xrange(_size16):
_elem21 = MVRResponse()
_elem21.read(iprot)
self.success.add(_elem21)
iprot.readSetEnd()
else:
iprot.skip(ftype)
elif fid == 1:
if ftype == TType.STRUCT:
self.ex = MVRException()
self.ex.read(iprot)
else:
iprot.skip(ftype)
else:
iprot.skip(ftype)
iprot.readFieldEnd()
iprot.readStructEnd()
AFAIK, support supports set. Any idea, how to resolve it.
