I am not having the problem with Python 3.9.12. I have found some references online about issues with the socket libraries in older Python releases.

Thank you,
I tried your code, but sadly It still hangs.
Also, I'm using uopy 1.2.0. I updated to 1.3.0, and I'm unable to establish a session. I keep looking at the documentation, but everything seems to be the same. I keep getting:
Error [81009] : The RPC failed
And in the logs I see this message:
2023-11-16 17:00:16,609 : 91525 : MainThread : _unirpc : __init__ : 169 ：ERROR : module 'socket' has no attribute 'TCP_KEEPIDLE'
I was hoping that maybe the new version would help with my uploading issue, but no idea why I'm not even able to connect :S As soon as I switch to 1.2.0 it connects with no issues and we are just having problems with uploading big programs.

Alejandro,
From the python side, you can just add it in the connection parameters, either in the uopy.ini file or when you make the connection:
def makeconnection(user, password):
config = {
'user': user,
'password': password,
'service': 'uvcs',
'host': 'localhost',
'account': 'C:\\U2\\UV\\XDEMO',
'pooling': True,
'min_pool_size': 2,
'max_pool_size': 5,
'timeout': 300,
'encoding': 'GB18030'
}
thissession = uopy.connect(**config)
return thissession

Alejandro,
My python code and UniVerse are on the same server.
I created a big file, and keep expanding. At this time I am up to 16185840 bytes and it still works.
Note that it is fast in my environment where there is no network delay between the client and the server.
Is your UniVerse on the same system as your python code?
Have you tried increasing the timeout on the uopy connection?

Hi,
It's been a long time, but I need to revive this. I still have this issue. @John Jenkins, thanks for the suggestion, but the fix is something that the CSV library has available. I tried looking for something in the UOPY documentation, but I don't see any parameter we can pass to override any max-size variable.
@Mike Young I tried your code suggestion; this is what I got:
Traceback (most recent call last): File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_unirpc.py", line 179, in receive return self._socket.recv(buf_size)socket.timeout: timed outThe above exception was the direct cause of the following exception:Traceback (most recent call last): File "/Users/test/unidata.py", line 53, in pushFile udfile.write(fname,lines) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_file.py", line 345, in write resp_code = self._call_server(in_packet, out_packet) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_uniobject.py", line 29, in _call_server self._session.rpc_call(in_packet, out_packet, in_exec) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_session.py", line 200, in rpc_call self._rpc_connection.call(in_packet, out_packet) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_unirpc.py", line 72, in call self._read_packet(in_packet) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_unirpc.py", line 123, in _read_packet in_packet.receive(self.rpc_socket) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_unirpc.py", line 252, in receive self.header_buffer = rpc_socket.receive(_PACKET_HEADER_SIZE) File "/Users/test/Library/Python/3.9/lib/python/site-packages/uopy/_unirpc.py", line 182, in receive raise UOError(ErrorCodes.UOE_RPC_TIMEOUT) from euopy._uoerror.UOError: Error [81015] : The connection has timed outDuring handling of the above exception, another exception occurred:Traceback (most recent call last): File "/Users/test/unidata.py", line 91, in <module> compileFile(dname, fname) File "/Users/test/unidata.py", line 66, in compileFile pushFile(dname,fname) File "/Users/test/unidata.py", line 54, in pushFile except UOError as ue:NameError: name 'UOError' is not defined
The connection is timing out. Super weird, it is actually not throwing a UOError. And remember, If I try a file of 127Kb it goes without a problem...
If anyone has any other ideas, please let me know.
Thanks in advance
Alejandro

Alejandro,
Does this help at all - it mentions a Python 128K limitation

Hello, it is me again fighting UOPY.
I need to push a big file, and after multiple testing, I found that I could not push a file bigger than 128K. The process hangs there forever.
Is this a Unidata limitation or a UOPY limitation? Is there a way to change this limit?
Here is my code:
def pushFile(dname,fname):
f = open(dname+'/'+fname,'rb') lines = f.read()
f.close()
print('done reading')
# print(lines)
udfile = uopy.File(dname,session=_session)
udfile.write(fname,lines)
udfile.close()
print("file uploaded")
Any help is greatly appreciated.
