Fix to suppress printing of "unsupported key: 17" for "not sorted" folder.

unsupported sort key: 17

During the run of DEBUG BUILD of thunderbird, I get an output like
the following 34 times.

unsupported sort key: 17


I tracked down to this output to the following code in
ConvertSortTypeToColumnID() in 
https://mxr.mozilla.org/comm-central/source/mail/base/content/commandglue.js

See line 261

187 function ConvertSortTypeToColumnID(sortKey)
188 {
189   var columnID;
190 
191   // Hack to turn this into an integer, if it was a string.
192   // It would be a string if it came from localStore.rdf
193   sortKey = sortKey - 0;
194 
195   switch (sortKey) {
196     case nsMsgViewSortType.byDate:
197       columnID = "dateCol";
198       break;
199     case nsMsgViewSortType.byReceived:
200       columnID = "receivedCol";
201       break;

	  ...

244     case nsMsgViewSortType.byAttachments:
245       columnID = "attachmentCol";
246       break;
247     case nsMsgViewSortType.byCustom:
248 
249       //TODO: either change try() catch to if (property exists) or restore the getColumnHandler() check
250       try //getColumnHandler throws an errror when the ID is not handled
251       {
252         columnID = gDBView.curCustomColumn;
253       }
254       catch (err) { //error - means no handler
255         dump("ConvertSortTypeToColumnID: custom sort key but no handler for column '" + columnID + "'\n");
256         columnID = "dateCol";
257       }
258 
259       break;
260     default:
261       dump("unsupported sort key: " + sortKey + "\n");   <------ HERE
262       columnID = "dateCol";
263       break;
264   }
265   return columnID;
266 }


Basically, the code is printing "unsupported sort key:" message
since the key is not handled in the switch statement.

But then what is this "17", then?

I looked for the defines for the values used in case labels.
They are defined in the following file.

https://mxr.mozilla.org/comm-central/source/mailnews/base/public/nsIMsgDBView.idl#60

60 interface nsMsgViewSortType
61 {
62   const nsMsgViewSortTypeValue byNone = 0x11; /* not sorted */
63   const nsMsgViewSortTypeValue byDate = 0x12;
64   const nsMsgViewSortTypeValue bySubject = 0x13;
     ...
79   const nsMsgViewSortTypeValue byCustom = 0x22;
80   const nsMsgViewSortTypeValue byReceived = 0x23;
81 };


17 is 0x11, the value of |byNone|.
So the code was complaining that a folder (or is it a newsgroup?)
is "not sorted" somehow.

I don't know the life cycle of a folder, but somehow such "not sorted"
folder is created during the test run of "make mozill" of thunderbird.
(And for that matter, I see this unsupported key: 17 message 
during my use of TB at the office. Usually, I see it when I do a
global search across folders. So maybe one or more folders in my setup have this "not sorted" property somehow.)

When a folder is "not sorted", the code sets the sortKey |columnID| to
"dateCol", which seems a reasonable default.
So maybe we don't have to print out the warning in the case of
|byNone|.
A fix is suggested as attached.

Since the code is very old(?) and I could not find meaningful hg blame
output, I am requesting review from Daivd (mozilla@davidbienvenu.org)

TIA


Actually there is similar code in SeaMonkey as well.
I searched the string using the following command and got the output
as below. 
find . \( -name ".hg" -prune \) -o \( -type f -print \)  | xargs egrep "unsupported sort key"
./mail/base/content/commandglue.js:      dump("unsupported sort key: " + sortKey + "\n");
./suite/mailnews/commandglue.js:      dump("unsupported sort key: " + sortKey + "\n");

The same fix is needed for both
TB and SeaMonkey. So I am attaching the patch for both of them.

PPS: I noticed during the run of "make mozmill" test suite of
DEBUG BUILD of thunderbird. 

PPPS: Patch was checked in TB tryserver submission.
(No new problems were found other than the permanent orange type of errors.)

https://tbpl.mozilla.org/?rev=13f6001f5c01&tree=Thunderbird-Try

PPPPS: If a folder should not have "not sorted" property, then
maybe this warning output is useful.
But as far as I know, my office TB usage printed out this warning for a long time (at least a few years). So it seems OK to have "not sorted" property for folders.

Thank you for fixing the MIME format of the uploaded file. The unbearable heat in Tokyo area distracted me obviously.

We should add a comment here such as:

// In the case of None, we default to the date column
// This appears to be the case in such instances as
// Global search, so don't complain about it.

Thank you for your review.

I have decided to create a new bugzilla entry for the suite portion so that the fix here can be applied first, and then when I find some reviewer (I will post an inquiry to mozilla.dev.apps.seamonkey) for
suite part, he/she can decide to pick up the patch, etc.

TIA

TB-only patch with your comment follows.

Final patch (split for TB only) (carrying over r=Standard8+)

See previous comment.
