Small bug in nsXmlRpcClient.js implementation. The + operator adds numerically
instead of concatenating. The patch is very simple.

The correct patch for the Date problem in nsXmlRpcClient.js script

I got the original patch backwards. . .

I was too terse in describing this minor yet troublesome bug. Perhaps this
clarification will attract more attention.

In function iso8601Format(date) of nsXmlRpcClient.js, the local variable
"datetime" is first assigned a number (the year). The month must be appended to
that with a "0" prefix if the month is lesser than 10. For single digit months
the *string* '0' is added to the original datetime variable turning it into a
string. Further uses of the '+' operator will then concatenate properly.

For double digit months, the '0' string is NOT appended to datetime so it
remains a number. When the '+' operator is used to concatenate datetime and
month it incorrectly *ADDS* the year and the two digit month!

I use XML-RPC extensively as part of a larger protocol and this change is *so*
trivial to implement I suggest it should form part of Mozilla 1.0 candidate even
though the cut has been made.

Looking for an sr= please.  If no one on the cc list can, then please let me
know who can.  It's a very simple JS fix.
looks like the "day" code a lone below has the same problem.

var day = date.getUTCDate();
datetime += (day < 10 ? '0' + day : day);

I already had thought of that.  |datetime| is guaranteed to be a string, so
there's no problem adding an integer because the integer will be converted to a
string and appended.

After this patch was checked on the branch, bloat test were up by ~600KB. The
only other checkin occurred in the same time frame was a Mac only one (bug
141330), while the stats were seen on a linux box. Maybe this will need some
more investigation...

This patch can't be accountable for any bloat. It is way too simple as the only
problem was a missing cast. No logic was added or ammended. What you mention is
strange, but I wouldn't start looking here.

Can anyone provide a test case so that this bug could be verified

I reported this bug originally. I have no problems with it as the patched
applied for RC2 (or RC1, can't remember) solved it.

My application is too large and interdependent (read as: messy) to post here but
the code following should suffice. Point it to some webserver and tcpdump the
POST request. You don't need to set up anything on the other side because the
problem was the request body. You will see that the date format now adheres
properly to ISO 8601, as opposed to loosing required digits in the date format
because digits were added instead of concatenated.

var xmlRpc=Components.classes['@mozilla.org/xml-rpc/client;1']
var someDate=xmlRpc.createType(xmlRpc.DATETIME, {});
someDate.data=new Date("2002/10/31");

var listener = { /* ignoring everything */ };
xmlRpc.asyncCall(listener, null, 'someHandler.someMethod', [ someDate ], 1);
