easysnmp2's Issues

Fails to build on Solaris 10 - simple_bitarray.h missing newline

Builds on Solaris 10 fail with error:
easysnmp/simple_bitarray.h:259:7: warning: no newline at end of file

Adding a newline to the end of the file fixes the issue.

Memory leak

Hi!

I've come across easysnmp2 as I found a memory leak using easysnmp library... Unlucky I got the same issue using easysnmp2 :-(

I'm using a Session object to perform several get, also with multiple oid at the same time, could it be that the problem?

Received signal SIGSEGV, Segmentation fault with repeated requests

I use the Bottle framework with a Paste server and when I query several devices simultaneously in SNMP, the Python crashes with an exit 139 code.

When I use the PySNMP library I don't have this problem but the requests are much longer, hence the fact that I want to use your library.

Debug with GDB : gdb -ex r --args .venv/bin/python3 -m my_module

Thread 8 "python3" received signal SIGSEGV, Segmentation fault.

Does not work on Ubuntu20.04 LTS due to libsnmp30 dependency

The newest easysnmp2 version 0.3.1 needs libsnmp30, but Ubuntu only provides libsnmp35.
Is it possible to allow newer libsnmp versions or lower the version restrictions?

get_bulk doesn't return all the values (net-snmp bug?)

When I do a get_bulk() on .1.3.6.1.2.1.47.1.1.1.1.7, I get 26 values.
When I do a get_bulk() on .1.3.6.1.2.1.47.1.1.1.1.2, I get 26 values.
When I do a get bulk on the two of them together, I get 49 values.

This is problematic because the results don't return in pairs, and of course, because the last 3 values were omitted.

Unfortunately, this is exactly the same result I get with net-snmp on my Mac :-(
