Checking Connection to github connect failed #14307

Open iplayfast opened 5 months ago

iplayfast commented 5 months ago

Is there an existing issue for this?

Problem description

02:03:14 During initialization the error "/home/chris/.local/lib/python3.10/site-packages/PySide2/QtUiTools.abi3.so: undefined symbol: _ZdlPvm, version Qt_5" occurred in /home/chris/.local/share/FreeCAD/Mod/btl/./InitGui.py

I'm also finding that when I click on the add on manager, it says that it is "Checking for Connection to githu" and just sits there. I don't know if it is related or not.

Seems like an issue in the blt addon. Can you remove this folder under Mod/ and try again?

iplayfast commented 5 months ago

That got rid of the 02:03:14 During initialization the error "/home/chris/.local/lib/python3.10/site-packages/PySide2/QtUiTools.abi3.so: undefined symbol: _ZdlPvm, version Qt_5" occurred in /home/chris/.local/share/FreeCAD/Mod/btl/./InitGui.py problem.

Still have the "Checking for Connection to github" dialog just sitting there.

from the command line:

connect failed: No such file or directory
maxwxyz commented 5 months ago

@chennes FYI, it seems to get no connection when launching the addon manager

macdroid53 commented 5 months ago

Not sure if this is the same issue, but this showed up yesterday and today on Manjaro. Gets to this point and hangs indefinitely. Screenshot_20240607_080443

Jookia commented 4 months ago

Is this fixed in dev?

chennes commented 4 months ago

Yes (at least, it should be!).

maxwxyz commented 4 months ago

So this issue can be closed?

iplayfast commented 4 months ago

As of July 12, 2024 it's not fixed.

chennes commented 4 months ago

Then we need to start to gather more information (the connection check failing is a symptom of many different unrelated problems). Can you please turn logging on and paste in the output?

iplayfast commented 4 months ago

I've been doing git bisect but have not found it. How do you turn on logging?

luzpaz commented 3 months ago

Is this related to #15059 ?

chennes commented 3 months ago

Is this related to #15059 ?

No -- that was a Qt6 issue.

Well, that's a dead end, there's nothing at all in there. Can you try, from the FreeCAD Python Console:

import NetworkManager
NetworkManager.InitializeNetworkManager()
NetworkManager.AM_NETWORK_MANAGER.blocking_get("https://api.github.com/zen")
iplayfast commented 3 months ago

Rebuilt today July 19,2024 same issue persists.

From the menu

Trying your commands

NetworkManager.InitializeNetworkManager()
NetworkManager.AM_NETWORK_MANAGER.blocking_get("https://api.github.com/zen") < stalls here

If I push enter again it says 

Previous command still running!

ctrl-c gives

Other notes: I've tried renaming .local/share/FreeCAD to .local/share/FreeCAD1 (no difference) I've tried downloading FreeCAD-0.21.2-Linux-x86_64.AppImage and it does the same thing.

HOWEVER Ondsel_ES_2024.2.2.37240-Linux-x86_64.AppImage works properly! Compiling freecad from the ondel github repo https://github.com/Ondsel-Development/FreeCAD/tree/2024.2.2?tab=readme-ov-file doesn't work, so they are doing something different.

ping!

chennes commented 3 months ago

Based on your console results, it looks like a Qt bug -- where are you getting the executable?

iplayfast commented 3 months ago

iplayfast commented 3 months ago

Interesting. I just downloaded the freecad appimage https://github.com/FreeCAD/FreeCAD/releases/download/0.21.2/FreeCAD-0.21.2-Linux-x86_64.AppImage and it has the same issue. This one doesn't use local libraries at all so I think we can rule out qt error, although if it works for others, I can't image what it could be.

chennes commented 3 months ago

Well, it's presumably some odd interaction between Qt and your particular networking stack. The fact that Ondsel works is very interesting, what are the various Qt versions involved with Ondsel, the 0.21.2 appimage, and your local compile?

iplayfast commented 3 months ago

Well as they are app images (ie statically linked) I have no idea. Ondsel is an app image and works, Freecad app image doesn't. My compile doesn't. All I can show you is my compile stuff (above). If it's working for you, what does yours say when you do an ldd of FreeCAD ? My networking stack is pretty generic. I've added an apache server on my computer, but that shouldn't affect anything. I can browse github and I can curl github. So ?

The AppImage is not working for me either. Python console output:

Network Manager Error: __reply_finished not called by a Qt signal

Tried with a native install via apt and the output has another reference to Qt:

Comparing libraries linked by both, they are the same except that the compiled version includes libboost filesystem.so.1.74.0 and libfmt.so.8 The apt install version doesn't have those, but includes libzipios.so.0 Hopefully a clue.

chennes commented 3 months ago

The version information you get from ldd isn't enough, I'd like to know the precise versions of Qt that are working versus not-working. Can you post the "About FreeCAD" info from these?

iplayfast commented 3 months ago

Working on Bisecting git, Earlier versions fail, but have this message

chennes commented 3 months ago

Is 5.15.3 the latest version of Qt available on Mint 21.3?

iplayfast commented 3 months ago

Yes, Or I could install 6.2.4, but I think the 5 is the standard one.and I don't want to break packages. It's strange that it used to work, but now doesn't.

Here's a shot in the dark.

https://stackoverflow.com/questions/35236341/qnetworkreply-error-network-access-is-disabled

I met the same problem. After seeing the official material of QNetworkAccessManager, I found the solution. After initializing QNetworkAccessManager，you should add the codes below:

net_mgr->setNetworkAccessible(QNetworkAccessManager::Accessible);
chennes commented 3 months ago

6.2.4 would not help you anyway, FreeCAD only supports 6.4 and up. If you are comfortable editing a Python file you can modify NetworkManager.py to implement the suggestion you found to see if it works (the Python version of the call, not the C++, of course).

iplayfast commented 3 months ago

I tried editing the file, but could not figure out where to put it.

iplayfast commented 2 months ago

Should this issue be considered a blocker, since anyone with an up to date ubuntu or linux mint will have this problem. It appears to be a qt 3.15.3 vs qt 3.15.2 problem but it is a major problem for getting updates.

chennes commented 2 months ago

No one else has reported the issue -- I have tested on Ubuntu 20.04, 22.04, and 24.04. It appears to be a combination of a particular version of Qt and some particular hardware configuration. Considering that there is always a workaround (addons can be installed by downloading the Zip, or by using git clone on the command line), this does not block the release of 1.0.

iplayfast commented 2 months ago

@ClayShoaf also said that he was having the same problem earlier in the thread. I know I can work around it, I just would hate for the release to have this problem with many unsuspecting new users. The versions that you tested on, were any of them qt.3.15.3?

chennes commented 2 months ago

@ClayShoaf was testing 0.21.2, which has a number of known bugs in this part of the networking code.

I'm open to suggestions for how to debug or work around the problem: the core of the Addon Manager networking stack is simply stalling out on your machine, not only failing to return the expected data, but both failing to report a connection failure, and failing to timeout. We're getting exactly zero diagnostic output. There's not much to go on here. You could try adding some print statements in NetworkManager.py to try to isolate the actual Qt call that is failing. There's a chance that it's something that could be coded around.

iplayfast commented 2 months ago

I added tracking to Networkmanager.py and addonmanager.py which should track any blocking getmessage. Now when I start freecad and try to updateaddons, I get the following

connect failed: No such file or directory
AM_NETWORK_MANAGER is None
hello

No blocking requests

AM_NETOWRK_MANAGER is None on initiailzation (which is expected) Hello is the start of the getting addons

  def start(self):
        """Start the connection check"""
        print("hello");
        status = NetworkManager.AM_NETWORK_MANAGER.get_status()
        print(status)  # Outputs "Blocked by request to [URL]" or "No blocking requests"
        self.connection_checker.start()
        self.connection_checker.success.connect(self._check_succeeded)
        self.connection_checker.failure.connect(self._network_connection_failed)
        self.signals_connected = True
        print("connected should be True")
        status = NetworkManager.AM_NETWORK_MANAGER.get_status()
        print(status)  # Outputs "Blocked by request to [URL]" or "No blocking requests"
        # If it takes longer than a half second to check the connection, show a message:
        self.connection_message_timer = QtCore.QTimer.singleShot(
            1500, self._show_connection_check_message
        )

So it looks like there are no blocking requests but the connection is not working, and does not timeout after 5 minutes.

running again says

AM_NETWORK_MANAGER already initialized
hello
No blocking requests
connected should be True
No blocking requests

So the first request did not block eithe, or was canceled when I cancelled the dialog.

If you can think of anything else to try, I'm game.
