Hi,

Please find the attached patch to fix the below 2 bugs.

RM 1603: [Web Based] Export database failed if object contains double quotes.
RM 1220: Backup database is not working with special characters

The issues which were fixed:

1. Client side data were not unescaped
2. Required command line arguments were quoted twice 

This is not working for me: I tested using Table Export as per Fahar's instructions. As I'm in desktop mode, the first problem was that we get an error at line 210 of import_export/__init__.py, because get_server_directory returned None for the directory. If I fix that, then the job says it's created, but as far as I can see, nothing else happens.
hmm.. 

Yes, but please see my followup message. There's clearly something funky going on with the process tracking - for whatever reason it didn't pick up this process until after a restart, and per the bug I escalated earlier (which I think is essential to fix for 1.1 in a little over a week), it doesn't always detect completed processes and then keeps re-showing the alert.
 
 
The problem here is that, until we click the "Click for details here" link and close the another details dialogue, the acknowledgement does not send to the server. So, it keeps re-showing the alert.

I think, we need to clearly mention the steps on the alertify notifier itself, so the user can get the idea. 

Dave/Ashesh,
Any other suggestion?
We can give a acknowledge link along with 'Click here for details' link to delete the status, logs, when clicked.
Dave? 
 

Secondly, this patch seems to push quoting responsibilty to the front end.
No - that's not the case, we're using _.escape(..) function on the node's label to fix the issue of XSS vulnerability on client side.
Hence - during sending back the data, we're using _.unescape(..) function to return the same data coming sent by the server.

Ahh, OK - I see.
 

Though - IIRC - we have a original label stored in another variable '_label', which we can use it instead of unescape it again. 

Right, as we've done in many other places.
 
I have replaced  _. unescape with _label

 
This doesn't seem right, because we might want to use the RESTful APIs for another purpose in the future, which would mean needing to re-implement quoting if something else uses an affected API.
As I explained above, it wont affect the RESTful API.

Yep. Thanks for setting me straight.
