Description

After requesting the capabilities from our SDE WMS Layers e.g.:

http://wagisimp.ilmenau.baw.de/cgi-bin/mapserv4?map=/srv/www/htdocs/mapserv_WaGIS/WaGIS_FT_21-Recht.map&REQUEST=getCapabilities&SERVICE=WMS&VERSION=1.1.1&

or:

http://wagisimp.ilmenau.baw.de/cgi-bin/mapserv4?map=/srv/www/htdocs/mapserv_WaGIS/test2.map&REQUEST=getCapabilities&SERVICE=WMS&VERSION=1.1.1&

I get a truncated XML back. (Sorry the serevr is only in our intranet.) This
looks like:

The getcapabilities with the WMS version 1.1.0 work. The getmap works with WMS

I think I've heard of a similar issue before with SDE (maybe it was from you).
I'll reassign to Howard since we're not setup to test with SDE and this has
probably more to do with the SDE driver than with WMS.

comment:2 by hobu, 20 years ago

First thing to try:
Please specify a version to query from in the connection string similar to what
is outlined on the wiki page:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?MapServerSDE

On the SDE Data string, DATA 'wagis.rl_vg250_kreis,gid', is gid the ObjectID
column, or the column that contains the actual shape data?

Also, please turn off the class item stuff on the sde layer, so we can eliminate
the kind of flaky regex support that sdelayers have in mapserver

Report back, and if you're still having problems, I'll try to replicate with my
own setup.

comment:3 by norbert.thieme@…, 20 years ago

Thanks for the reply.

Like I mentioned the SDE stuff works with WMS verion 1.1.0 and the getmap also
works with version 1.1.1 - only the getcapabilities don't work with this
version. If I use the mapfile in the normal way with the Mapserver there is also
no problem. So I don't know if the class item stuff and the connection is the
problem. But I tried:

I turned off the class item stuff and put the color/outlinecolor into a style
object in the class. The output is still truncated.

If I understand the wiki page correct the SDE.DEFAULT should be enough for the
connection string because the database we use is a kind of read only one - so no
editing is made on it.

The gid field is the field with the geometry / actual shape data.

Perhaps the problem is the communication between the Apache and the Mapserver.
Is it possible that the Apache stops sending before the XML is complete? Can I
check that? How? I tried it with debug on but the logs don't tell a problem.

comment:4 by dmorissette, 20 years ago

Apache would not truncate the output with no reason. Seems very much like
mapserv is crashing in the middle of the generation of the Capabilities. To
verify this, you could run your request at the command line with:

./mapserv
"QUERY_STRING=map=/srv/www/htdocs/mapserv_WaGIS/WaGIS_FT_21-Recht.map&REQUEST=getCapabilities&SERVICE=WMS&VERSION=1.1.1"

Note that the double quotes are important.  

When you run the above command you'll probably see a truncated XML output as
well, and if my guess is right the output will end with "segmentation Fault" or
something like that.

If you get a segmentation fault, then we need to find out where and why... that
can be hard to do remotely if you are not familiar with GDB. At a minimum
getting a GDB call stack would be a good start. To do this, run:

  gdb ./mapserv
  ....
  (gdb) run
"QUERY_STRING=map=/srv/www/htdocs/mapserv_WaGIS/WaGIS_FT_21-Recht.map&REQUEST=getCapabilities&SERVICE=WMS&VERSION=1.1.1"
  ....
  ... and when the program stops/crashes...
  (gdb) bt

... and send the output of the bt command in this bug report.

dependson:	→ 767

Do you have opportunity to update to CVS MapServer?  Ah, this is all starting to
make a little more sense now.  I fixed a bug (#767) in SDE support that was
causing it to segfault for layers with shared connections.  

If you have two layers in SDE with the same connection string, the old code
(4.2) will try and free up resources from both of the shared layers, which
causes a segfault.  The new code leaks in the face of indecision instead of
trying to free up those resources.

comment:6 by sgillies@…, 20 years ago

hobu, check out bug 670.  Daniel mentioned that it would be nice to be able
to handle just these kind of exceptions during capabilities output.

comment:7 by dmorissette, 20 years ago

Actually in this case we're probably talking about a segmentation fault, which
is not a trappable exception of course.

comment:8 by norbert.thieme@…, 20 years ago

I have no time at the moment to get the cvs version but I tried gdb and the
output is:

#0  0x4087c6e9 in free () from /lib/i686/libc.so.6
#1  0x08077a49 in msSDELayerClose (layer=0x9e9) at mapsde.c:492
#2  0x08065f46 in msCloseConnections (map=0x40f10008) at mapfile.c:4597
#3  0x080645ad in msFreeMap (map=0x40f10008) at mapfile.c:3885
#4  0x08052378 in main (argc=1089536008, argv=0xbfffec54) at mapserv.c:974
#5  0x408264c2 in __libc_start_main () from /lib/i686/libc.so.6

BTW, the output looks OK here - the xml seems to be complete and the seg fault
appears after that:

...
  </Layer>
</Capability>
</WMT_MS_Capabilities>

Program received signal SIGSEGV, Segmentation fault.

comment:9 by hobu, 20 years ago

Norbert,

This is definitely the bug that was fixed in 767.  You'll have to update to CVS
or wait for 4.2.2, which should have the patch backported to it.

Howard

Howard, will you backport the patch to 4.2?  I'm not setup to test with SDE
myself so I can't do it.

comment:11 by hobu, 20 years ago

Resolution:	→ fixed
Status:	new → closed

done

comment:12 by dmorissette, 20 years ago

Thanks. BTW I have added a note about this fix to the HISTORY.TXT in the 4.2 branch.

comment:13 by norbert.thieme@…, 20 years ago

Resolution:	fixed
Status:	closed → reopened

Sorry I haven't checked this when the version 4.2.2 was available. But now with
version 4.2.4 I tried but it still fails with a segmentation.

comment:14 by hobu, 20 years ago

Do you have any opportunity to try CVS MapServer?  In CVS, SDE was upgraded to
the new connection pooling API, which I believe fixes this problem (and many
others with connection pooling).  4.4 (which will be based on current CVS) is
due out in a couple of months.

comment:15 by assefa, 19 years ago

Is this still an issue with lastest versions ? If not please update the bug so 
we can mark it as Fixed.

comment:16 by hobu, 19 years ago

Resolution:	→ fixed
Status:	reopened → closed

marking fixed.  The new connection pooling should have cleaned this up.
