Ctrl-R not working?

[ownedbycats]

The problem was fixed for me with 5.3, but I use a custom swap size.

There is another possible, fix. I could have calibre manually shutdown the single instance mutex and listening socket before restart. So then even if the parent process sticks around for an indeterminate time, it wont prevent the child from running.

Same error message from portable 5.3

Traceback (most recent call last):
  File "calibre\gui2\main.py", line 573, in main
  File "calibre\gui2\main.py", line 522, in create_listener

  File "multiprocessing\connection.py", line 645, in __init__

PermissionError: [WinError 5] Access is denied

.

I just installed the portable, ran it, left everything at default and then typed Ctrl R. This is repeatable.


I'll look at the other issue re paging setup when I have time.

Does this require a binary release to test or can I run from source?

You can run from source.

Was using custom page file settings. Changed to allow Windows to manage, reboot, checked it was set then tried Calibre again.
And the result, erroring still on Ctrl R.

So no difference between custom or managed.

Okay, I have cloned the code from github, setup from source and tested that it was done by adding a "hello world" to __init__.py. Ran debug to ensure that it was using the source and yes it was.

Then ran calibre which showed version "5.3*" in the gui. And nothing changed except the text showing the traceback

calibre, version 5.3.0
ERROR: Cannot start calibre: <p>calibre is already running.</p><p>calibre may be running in the system tray, in the lower right region of the screen.</p><p>If you are sure it is not running,  try rebooting your computer.

@georgemk: And this is after how much time?

[chaley]

@georgemk: have you tried booting in safe mode and checking that the problem is still there? Some "security suite" could be gating access to networking based on its own idea of what is proper.

[georgemk]

From Ctrl R to error box is 4 seconds now.

And we have a winner here. Booted into safe mode with network and Ctrl R and Ctrl Shift R worked every time. I tried it multiple times without any error.

Booted back into normal Windows mode and error occurs first time of asking.

The security suite in use is just Windows 10 Security, no 3rd party tools installed.

So does anyone have an idea for where I look for a setting to change?

[kovidgoyal]

It's not even networking, its a local named pipe, must be a pretty aggressive antivirus.

[georgemk]

I've found a bit of a solution or a further problem depending on your point of view.

I've uninstall Calibre and then installed it again form the same MSI I'd used for earlier this week when I upgraded to 5.3.

Now I can restart Calibre from the Plugin dialog restart button. (tested by adding 2 plugins in 2 separate goes) But not by keyboard nor the Preferences

If it doesn't fail in safe mode then something that is being started when you boot is causing the problem. Run the Windows Task Manager (start / Windows System / Task Manager or CRTL-ALT-DEL then select Task Manager), click on the Startup tab then look for things that you don't know what they do.

You could also disable some, reboot, then see of the problem is still there. If so, reenable the ones you stopped and disable some others. If not, reenable one by one until the problem comes back.
