zimdicator.py : ValueError: Expecting , delimiter: line 1 column 25299 (char 25299)

Looks like more JSON decoding issues, the thing is, I can't reproduce this one. Is there anyway you could find out what part of JSON returned by zimbra causes the error (located at chat 25299 in your case).

To do that, try this. Login into zimbra web client, open a new tab in browser and type this url

https://<email address hidden>/?fmt=json&query=is:unread

copy the content of that page into text editor and look at what is at char 25299.

That would probably help a lot. You breaking my stuff, helps me improve it so keep on breaking ;-)

Hi,

OK, since last night the number of unread mails has increased. Here is the revised traceback.

Traceback (most recent call last):

ValueError: Expecting , delimiter: line 1 column 39725 (char 39725)

I added a line to print the contents of json_str and redirected the output of zimdicator .py to a file. The then out a few chars either side of the offending 39725 with the following.

cat json.txt | cut -c 39710-39740

Here is string that fragment.

e has vanished: \\"/var/lib/pos

Hope that helps.

Regards, Martin.

Hi, could you expand the fragment a bit more? It' would help to maybe see the whole "string", that is causing this issue.

Thanks,
M

Hi,

zimdicator is encountering un-escaped double back slashes (\\) in the string, despite your replacement for '\\' to '\\\\'?! Had me stumped, seemed to me your replacement should work. But evertime I debug it, it is choking on a double slash. So I did some reading, the following are informative but didn't help get me to a solution.

http://stackoverflow.com/questions/1505454/python-json-loads-chokes-on-escapes
http://stackoverflow.com/questions/983855/python-json-encoding

I've switched to XML as data transport format as it seems that Zimbra doesn't follow escaping conventions in JSON. Hope this resolves all this escaping issues and allows us to move forward.

Let me know if it works. Also there is initial notify-osd support in trunk, testing is needed. If it all works OK, i'll make a new release as it seems 0.1 is mostly unusable.

Cheers,
M
