Here's a version of KU that logs to .adds/kobo-uncaged/ku.log instead of syslog.

It might help.

MGlitch · 12-17-2020, 02:37 AM

That's done the trick, at least in terms of getting a logfile that isn't gibberish

I believe this is the relevant bit

If you need more let me know, interestingly no mention of any book either on my Kobo or in my Calibre library is in the log.

Thanks. This is weird. It seems that for some reason Calibre just stops sending NOOP packets, which then causes my code to timeout after a set period of time.

As for not seeing books in the log, I truncate each line to make sure the log doesn't balloon in size. You should see something like the following:

Code:

[Kobo-UNCaGED] 2020/12/17 19:45:44 [DEBUG] Processing SET_LIBRARY_INFO packet: {"libraryName": "Calibre Library", "libr
[Kobo-UNCaGED] 2020/12/17 19:45:44 [DEBUG] Wrote TCP packet: 6[0,{}]

[Kobo-UNCaGED] 2020/12/17 19:45:44 [DEBUG] Wrote TCP packet: 223[0,{"priKey":1,"uuid":"fd21303e-27bd-

That is the Kobo sending the list of books to Calibre.

EDIT: I guess the only thing I can think to try would be to restart both your Kobo, and Calibre, and see what happens. I must confess I'm a bit perplexed.

sherman · 12-17-2020, 03:04 AM

Ok, just noticed something even weirder. The timestamps for the NOOP packets seem to be getting further and further apart.

The first few are approx 2 seconds apart.

Then after 01:27:58, it seems to jump to around 10 seconds apart. Then approx 11 seconds, then 13 seconds

I have my timeout set to 15 seconds.

That log is showing something very very strange.

Maybe others may have an idea of what's going on here? I certainly don't. I've never seen a corrupted syslog like that.

It isn't corrupted. As of firmware version 4.25.x, the log files produced when developers mode is on are encrypted. There is some discussion of this and how to look at the syslog in Trouble Getting Kobo Sync with CalibreWeb working.

Ah.

Thanks for the heads-up on that.

I'm almost always using logread to read syslog, so I hadn't really noticed the change.

I think I'm definitely switching to a dedicated logfile for KU now.

I've not looked at the logs again, but I restarted the Kobo and Calibre and still getting the disconnect. Tomorrow I'll try rebooting my Mac and the router etc. and see if that helps, though I doubt it as every other indication of my network is healthy.

That's a relief actually. Was worried I'd need to do the deeper reset of my Forma.

sherman · 12-17-2020, 05:32 AM

So, looking at the Calibre source code, this is what sends the periodic NOOP opcode.

The documentation for that method indicates that the GUI thread periodically calls it.

The smart device driver sends a NOOP every five probes. The 'normal' time between NOOP opcodes appears to be 2-3 seconds, so each probe is probably around 500ms apart (I haven't actually checked the code to see what it is).

The issue MGlitch appears to be having is that there seems to be something preventing the probes from occurring at a 'normal' rate. If Calibre is idle, then the only thing I can think of that would cause this issue would be a misbehaving plugin.

Of course, this is all a bunch of speculation...

I've removed every user installed plugin, restarted Calibre. All pre-installed plugins are up to date. Issue persists. Log, though I dunno if it'll help clear anything up.

This is a headscratcher indeed.

I shall sleep on it to see if I receive any enlightenment.

As an interim measure, tomorrow I can increase the timeout period a bit to see if that helps for you, although it isn't really a proper solution.

sherman · 12-17-2020, 06:52 AM

One final request before I jump into bed if I may @MGlitch

Could you please post the entire log? I want to double check that the sequence of events happens as expected without irregularities.

If you don't want to paste it into a code block, feel free to attach it, or even PM it to me.

Thanks.

@sherman: FWIW, I'm seeing a similar pattern of a burst of NOOP every 2s for a while on connect, before it gets staggered a bit more towards ~10s.

It's been holding steady at ~10s for a few minutes now, and I haven't touched calibre at all during the experiment

.

(Calibre 5.7.2 on a Linux host).

The timestamps for the NOOP packets seem to be getting further and further apart. The first few are approx 2 seconds apart. Then after 01:27:58, it seems to jump to around 10 seconds apart. Then approx 11 seconds, then 13 seconds I have my timeout set to 15 seconds. That log is showing something very very strange.

The documentation for that method indicates that the GUI thread periodically calls it. The smart device driver sends a NOOP every five probes. The 'normal' time between NOOP opcodes appears to be 2-3 seconds, so each probe is probably around 500ms apart (I haven't actually checked the code to see what it is). The issue MGlitch appears to be having is that there seems to be something preventing the probes from occurring at a 'normal' rate. If Calibre is idle, then the only thing I can think of that would cause this issue would be a misbehaving plugin. Of course, this is all a bunch of speculation...

I shall sleep on it to see if I receive any enlightenment. As an interim measure, tomorrow I can increase the timeout period a bit to see if that helps for you, although it isn't really a proper solution.

I want to double check that the sequence of events happens as expected without irregularities. If you don't want to paste it into a code block, feel free to attach it, or even PM it to me. Thanks.
