Cannot access Content Server - even locally

[kovidgoyal]

@charles: From looking at the traceback, it looks like buildfullreg in route.py is returning an expression that contains a regex with a named group named /ajax. Which presumably comes from self.routelist having a part with name=/ajax

Why it should be doing that puzzles me.

[kovidgoyal]

The only difference that I can see between the ajax routes and the rest are that the ajax routes are unicode strings, the rest are not, (because of the from __future__ import unicode_literals in ajax.py)

Presumably, changing those strings to bytestrings should fix it, though given that I dont understand what the bug in routes is, I have no way to be sure.

[kovidgoyal]

Looking through the routes code, I have to say I am not impressed. I shall look into getting rid of it when I do my content server refactor. Mapping URLs to functions should not be that hard

It may be that updating to routes 2.0 will fix the unicode issue since it purports to support python 3, but given that it may break other things, it's not something I want to do.

This is why I was asking about languages. I was wondering if we had some character encoding issue that prevented all that string manipulation in buildfullreg from working.

Well I have committed the change to convert all routes to bytestrings, which may fix it for you in the next release.

Calibre behavior is unchanged in 1.27
Same error in 32 and 64 bit version

As 1.27 was released before Kovid made the change, you won't see this until 1.28.

Calibre 1.28 shows the same error

Could you post a calibre debug log for a session where the error occurred? Start calibre, click the triangle/arrow next to preferences, choose "Restart in debug mode". After calibre restarts, attempt to connect to the content server, then quit calibre. Post the output that appears in the window that pops up.

I did notice that port 8080 does not show up, but the port for wireless device connection 9091 (which I set instead of 9090). According to a responce from Steve, Calibre Companion) this should make no difference.

I now set to port to 9090 and suddenly the local access via Firefox worked.

-------------------------------------

Why is the wireless port selected causing this being unable to connect to the server on 8080?

I am puzzled. I did try this now 3 times 9090 wireless works, 9091 wireless fails.

Addition:
The 3 times I did not restart Calibre.
After restarting it using 9090 - no error.
Changing to 9091 again and restarting Calibre - no error.

Still puzzled - but it works now.

Thanks for all the help !

I agree with you, this is very puzzling. I wonder if the wireless device driver configuration file was somehow corrupted, and changing the port rewrote it. Or perhaps Kovid's changes made the difference, but they required changing a config file. I can see no reason that either of these should be the case, but clearly something changed.

BTW: Steve is correct. You can use 9091 as the CC if you want to. I am the author of the wireless device driver and co-author of calibre companion (CC). Does CC now work for you as it should?

[BumbleBernie]

Yes, CC works - but it needs always connection to Calibre, unless one downloads all books to the CC (too much for several 1000 books). I thought it could download just the catalog too.
