GNS3 2.1.1 release still contains 2.1.0 GUI

[david-ramsden]

Hello.

I upgraded my VM to v2.1.1 which seems to have completed without any issues.

But the 2.1.1 all in one release (https://github.com/GNS3/gns3-gui/releases/download/v2.1.1/GNS3-2.1.1-all-in-one.exe) still seems to contain the 2.1.0 GUI.

I tried uninstalling and reinstalling but same issue. I also noted that when I uninstalled GNS3 it was very slow to uninstall.

Also seen this in the GNS3 community forum: https://www.gns3.com/qa/ver-2-1-1-upgrade-from-2-1-0-ver

Or maybe it does contain the 2.1.1 GUI but someone forgot to bump the version number somewhere...?

Yep I think someone forgot to change gns3/version.py before making the release. So the build is 2.1.1 but it identifies itself to the server as 2.1.0.

Version was correct, it must be something different.

Hey @ziajka, I used uncompyle6 to decompile the version.pyc bytecode from my 2.1.1 install which shows:

$ uncompyle6 version.pyc
# uncompyle6 version 2.14.1
# Python bytecode 3.6 (3379)
# Decompiled from: Python 2.7.6 (default, Oct 26 2016, 20:30:19)
# [GCC 4.8.4]
# Embedded file name: ./gns3-gui\gns3\version.py
# Compiled at: 2017-11-09 01:42:11
__version__ = '2.1.0'
__version_info__ = (2, 1, 0, 0)
if 'dev' in __version__:
    pass
try:
    import os, subprocess
    if os.path.exists(os.path.join(os.path.dirname(os.path.abspath(__file__)), '..', '.git')):
        r = subprocess.check_output(['git', 'rev-parse', '--short', 'HEAD']).decode().strip('\n')
        __version__ += '-' + r
except Exception as e:
    print(e)
# okay decompiling version.pyc

As you see __version__ shows 2.1.0

Hi @syndgr, thanks. Indeed something is wrong, we had some issues with AppVeyor. during this release. It seems to be wrong packed. Also "Compiled at: 2017-11-09 01:42:11" says it's previous version.

I just noticed a comment on the GNS3 blog for 2.1.1 release announcement with someone else reporting the same issue.

As per their comment I deleted C:\Program Files\GNS3 without uninstalling GNS3 and then ran the 2.1.1 installer again. This fixed the issue. So quite possibly the release is good but there's a bug with the installer where it doesn't overwrite some files?

Per my screenshots my gns3.exe got overwritten but the decompile of version.pyc suggests this did not.

Installing GNS3 2.1.1 without first uninstalling 2.0.3 results in the following error when launching gns3.exe:

C:\Program Files\GNS3>gns3.exe

Something was wrong happened when all-in-one installer has been packaged. We will release 2.1.2 to fix this issue.
