[MapServer]"testSetExtent" in "testMapScript.py" generates error

[nsavard@…]

Running the test "testMapScript.py" and generates the error message below.  I
checked the scale value and I got "14.244422" which almost the same as you get
"14.173236".   Do you have an idea of what is causing this error?

This bug seems to have gone away -- all tests are now passing.  If you can 
confirm, I'll close it up.

[nsavard@…]

I updated MapServer source code June 2th 2004 7h54 from CVS and the error is
still there but at a different line number (see below).

Have you done a 'make clean'?  There has been a recent change to msMapSetExtent
and msAdjustExtent.

[nsavard@…]

Yes, I did a make clean, I ran configure and I did make.

[sgillies@…]

Hmmm.  Puzzling.

Here is what goes on when we call mapObj's setExtent:

  mapObj.setExtent
  mapobject.c:msMapSetExtent

Up to May 31, in revision 1.1 of mapobject.c, msSetExtent was returning a value
of 1 on success.  This was contrary to our exception of mapscript.MS_SUCCESS (0)
hence the failure in the test that you noted in comment #2.

since May 31, revision 1.2 of mapobject.c, msSetExtent returns MS_SUCCESS as
we expect.  So I am no longer getting the failure.  Additionally, I am not 
getting any failure with respect to the expected extent values.  The recent
work to msAdjustExtent must have fixed that.

Do you have revision 1.2 (or better yet 1.3) of mapobject.c?  If not, maybe we
have some makefile problem.

[nsavard@…]

I have mapobjectc revision 1.3 (see below).

Normand, how are you?

Does this bug still occur for you?  I do not see it in mapserver 4.2 or
4.3 (CVS).  Howard Butler can also not reproduce the bug in his nightly
builds.

[nsavard@…]

Hi Sean, I'm fine.  I'll verify that bug tomorrow.

[nsavard@…]

Verified on Fedora Core 2 and this bug could be reproduce.

[nsavard@…]

I meant verified on Fedora Core 2 and this bug could NOT be reproduce.  Tht's a
big difference.  Sorry for that.
