#3651 new defect

ST_Orientation crashes the backend

Reported by: postgispaul Owned by: robe
Priority: high Milestone: PostGIS SFCGAL
Component: sfcgal Version: 2.3.x
Keywords: windows Cc:

Description

Don't know if it's the number of points (100000+), or that there is something unusual in the geometry itself (it is valid though), but I have a polygon which when calculating the ST_Orientation of it, crashes the backend.

Tested on two systems: "POSTGIS="2.1.7 r13414" GEOS="3.5.0-CAPI-1.9.0 r4090" SFCGAL="1.2.0" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.11.1, released 2014/09/24 GDAL_DATA not found" LIBXML="2.7.8" LIBJSON="UNKNOWN" TOPOLOGY RASTER" "PostgreSQL 9.4.1, compiled by Visual C++ build 1800, 64-bit"

and

"POSTGIS="2.3.0 r15146" GEOS="3.5.0-CAPI-1.9.0 r4090" SFCGAL="1.3.0" PROJ="Rel. 4.9.1, 04 March 2015" GDAL="GDAL 2.1.1, released 2016/07/07 GDAL_DATA not found" LIBXML="2.7.8" LIBJSON="0.12" RASTER" "PostgreSQL 9.6.0, compiled by Visual C++ build 1800, 64-bit"

On both systems the postgres service crashes with a stack overflow. LOG: server process (PID 2440) was terminated by exception 0xC00000FD

My guess would be that some intermediate result is put on the stack instead of the heap (or passed by value instead of by reference).

Milestone: PostGIS 2.3.1PostGIS SFCGAL

I suspect this is something wrong with SFCGAL library itself so switching the milestone.

I confirmed crashes on my 9.6 windows 64-bit with 1.3.0. I'll test with git master SFCGAL and then report upstream if its still an issue.

comment:3 by postgispaul, 6 years ago

Thanks!

Any reason to not include this function in GEOS? Seems a bit overkill to install SFCGAL for this function only…

comment:4 by strk, 6 years ago

No reason, other than nobody implemented it.

comment:5 by dbaston, 6 years ago

I can put this into liblwgeom. A workaround that doesn't require SFCGAL is

ST_OrderingEquals(geom, ST_ForceRHR(geom))

comment:6 by strk, 6 years ago

Makes perfect sense for it to be in liblwgeom. I shall note it is ambiguous though, as orientation is a characteristic of a ring, not a full polygon. What does it mean for a polygon to be "clockwise" oriented ?

comment:7 by hmercier, 6 years ago

I can't reproduce the problem on my Linux box. Is it only windows specific ?

@strk : a clockwise polygon is a polygon with its exterior ring clockwise oriented and all its interior rings counter clockwise.

I also agree, it would make sense to have it in lwgeom rather than sfcgal

comment:8 by strk, 6 years ago

It's worth specifying the inner ring ordering in the ST_Or

comment:9 by strk, 6 years ago

Worth detailing the inner ring orientation in the ST_Orientation doc

comment:10 by robe, 6 years ago

strk are you able to replicate on your Linux?

That's my test against VC++ build. My PostgreSQL mingw debug build gives:

Still an issue on windows as of

PostgreSQL 13.1, compiled by Visual C++ build 1914, 64-bit

POSTGIS="3.1.0dev 3.1.0alpha2-157-gdfeaaac70" [EXTENSION] PGSQL="130" GEOS="3.9.0beta2-CAPI-0.15.1" SFCGAL="1.3.8" PROJ="6.3.2" GDAL="GDAL 3.2.0, released 2020/10/26" LIBXML="2.9.9" LIBJSON="0.12" LIBPROTOBUF="1.2.1" WAGYU="0.5.0 (Internal)" TOPOLOGY RASTER

But looks to be a windows only bug. So once I build a SFCGAL debug version I'll provide the case with more detail at https://github.com/Oslandia/SFCGAL/issues/137 and reopen.

Sadly this still crashes even using SFCGAL 1.4.0. I'll have to retrace.

comment:19 by robe, 5 months ago

Still crashes on 1.4.1

comment:20 by robe, 5 months ago

Iguess i need to rebuild SFCGAL with debug enabled. Puzzled why SFCGAL version is repeating lots of times in the debug output though seems a bit excessive
