Very slow shutdown

Fiat_Lux · 03-09-2017, 02:48 PM

All:

In shutting down Calibre, my current practice is to:

Click the close button;
Wait fifteen minutes;
Reboot the system (Windows)/run "kill -9 ####" (Linux)

Any suggestions on what to do, so I don't have to reboot the system/kill the process, to ensure that Calibre shuts down with in a reasonable amount of time.

FWIW, start up time is around 5 minutes.

Try starting Windows in safe mode and seeing if Calibre works as it should. If it does work, then the problem is with something you run when the system starts.

BetterRed · 03-09-2017, 03:08 PM

@Fiat_Lux - try running calibre with the --ignore-plugins switch, see ==>> Command Line Interface

If that improves shut down times disable any "Library Closed Plugins".

Those start/stop times are atrocious, what sort of computer - a DEC Rainbow PC with a couple of DECTapes for mass storage?

That makes me wonder if you're using some sort of VM environment - what happens if you run calibre in native Windows or Linux.

First what operating system are you using?
Second Please post the results of starting calibre in debug mode.

Code:

calibre-debug -g

You could create a brand new library, switch to that library, then see if Calibre shuts down and restarts much faster. If you have not vacuumed/compressed your Calibre library in a long time, its metadata.db file might have grown enormously simply due to the way that SQLite works when you change metadata, and irrespective of your adding new books. Library > Library Maintenance > Check Library. Calibre will vacuum/compress it for you.

Neither is running on VM.

The following is from a different user login, and after vacuuming the database.
There are no extensions installed for Calibre, on this user login.

Code:

Looks like those extensions are the cause of at least some of the long startup/shut down times.

Run calibre with --ignore-plugins and delete the #testauthor and #testcompare columns which have invalid templates

Fiat_Lux · 03-10-2017, 06:12 AM

And then after running

Code:

sudo calibre-uninstall
cd ~/.config/calibre
rm -R *
cd ..
rmdir calibre
cd
sh updatecalibre.sh
calibre-debug -g

this is what gets displayed
from startup to shutdown.

I deleted between half a dozen and a dozen custom columns, and startup time is just under two minutes. Shutdown time is under one minute.

To clear out any remaining debris from those custom columns, I am re-vacuuming the database.

The next step will be determine which of the extensions I had installed, I really need, and dispense with the rest.

After removing the 'unnecessary' plugins I would also delete corresponding settings files from the configuration plugins folder - e.g if I removed the Goodreads Sync plugin I'd also delete the Goodreads Sync.json file.

Their presence won't effect performance but if you were to reinstall the plugin next year you would inherit those old settings - which may not work come 2018.

Some plugins store configuration settings in the database, I don't think there's a simple way to remove no longer used library level settings. You could carefully edit them out of the metadata_db_prefs_backup.json file and then run Library Maintenance->Restore database. Two caveats - on a library of 150,000+ books that could take a while - take a copy of the metadata.db and metadata_db_prefs_backup.json files first, in case you break something. See next post.

@Fiat_Lux:

I noted from your Calibre debug log that you have Job Spy installed. So, you already have the GUI Tool that is shown in the attached image. It does easily what the quoted post was referring to.

Fiat_Lux Addict Posts: 393 Karma: 6700000 Join Date: Jan 2012 Location: Gimel Device: tablets	Very slow shutdown All: In shutting down Calibre, my current practice is to: Click the close button; Wait fifteen minutes; Reboot the system (Windows)/run "kill -9 ####" (Linux) Any suggestions on what to do, so I don't have to reboot the system/kill the process, to ensure that Calibre shuts down with in a reasonable amount of time. FWIW, start up time is around 5 minutes. Amber

If it does work, then the problem is with something you run when the system starts.

If you have not vacuumed/compressed your Calibre library in a long time, its metadata.db file might have grown enormously simply due to the way that SQLite works when you change metadata, and irrespective of your adding new books. Library > Library Maintenance > Check Library. Calibre will vacuum/compress it for you. DaltonST
