Error on startup

Error on startup was created by snowgoer540
I moved this from a topic under PlasmaC as there were two separate errors being posted at the same time and I didnt want it to go missed.

After updating yesterday evening, I started randomly getting this error on startup:
Traceback (most recent call last):
File "/home/plasma/linuxcnc-dev/lib/python/qtvcp/widgets/system_tool_button.py", line 106, in _set_user_system_text
self.setText(convert[int(data)])
KeyError: 0

Here is the terminal info from when it happens:



I am unsure what the cause is, or if it's a QTVCP problem, but as it pointed to a QTVCP widget, I figured I'd point it out here. Apologies if it was already reported. I do believe user robertspark also saw it forum.linuxcnc.org/plasmac/38521-gui-for...mac?start=150#194659

But for me, it is definitely the #1 error message when it happens.

Thanks!

The error message is a red herring, unfortunately.
This is not a consistent error on start up?
Isee lts of error messages from the Motion component indicating something is hanging early in the process.
you running 2.8 or master?

oh I can see your using master.
I get this when switching to conversational tab (in sim)

red herring? new term for me haha

Yea, master as you saw.

I dont see that particular error. Are you using buildbot or RIP?

RIP

You could try running qtvcp with -v (in the INI) to see if it gives any more info.

Interesting, They should work, Might want to get Phill to take a peek at them.

I added -v in the event it happens again, maybe I can provide additional info. I've only seen it in SIM not in a live table, so it could be a timing thing.

I think that "ini.z.maxlimit does not exist" is probably the real problem.

At a guess a HAL file is referencing those pins before the module that creates them is loaded. I am not sure which module creates them, though. I would have guessed motion, but they are not in the manpage

I think that's a fairly accurate guess. the maxlimit errors mostly shows up in SIM, but I have seen it once or twice on a live table. It always felt like a timing thing, so maybe we need to delve a little deeper into the order the modules are loaded.

I have not seen that error before.

ini.z.max_limit is netted by the handler file as the fourth command of the initialized function. Quick testing has shown that there is no difference whether it is the first or last command.

If I rename it to the wrong pin number then I get the following:
<commandline>:0: Pin 'ini.z.max_limits' does not exist
<commandline>:0: Pin 'ini.z.min_limits' does not exist
but I dont see these messages which are in the first post.
USRMOT: ERROR: command timeout
emcMotionInit: emcTrajInit failed
or further down:
waiting for component 'inihal' to become ready......

A bit more testing:

In the ini file, if I change:
SUBROUTINE_PATH         = ./:./qtplasmac:../../nc_files/subroutines
to a non existing path:
SUBROUTINE_PATH         = ./:./wqtplasmac:../../nc_files/subroutines
I get this error in terminal:
emc/task/emctask.cc 69: interp_error: File not open
File not open
emc/task/emctaskmain.cc 3070: can't initialize interpreter
plus this error from qtvcp:
Traceback (most recent call last):
  File "/home/phill/git/linuxcnc-dev/lib/python/qtvcp/widgets/system_tool_button.py", line 106, in _set_user_system_text
    self.setText(convert[int(data)])
KeyError: 0
so I don't think it is a qtvcp error, just qtvcp's reaction to not being able to load correctly because of some other pre-existing issue.
