Thusal Ranawaka (Jul 28 2020 at 04:34):@Sean Why is that?
Thusal Ranawaka (Jul 28 2020 at 04:45):Ran it as administrator.
Thusal Ranawaka (Jul 28 2020 at 04:46):It worked, I think.
Sumagna Das (Jul 28 2020 at 04:48):running something as administrator fixes many things most of the time but it has its own risk....
Thusal Ranawaka (Jul 28 2020 at 04:48):Yeah
Thusal Ranawaka (Jul 28 2020 at 04:49):Usually setups run on normal click
Thusal Ranawaka (Jul 28 2020 at 04:49):But for this one
starseeker (Oct 05 2022 at 03:16):@Sean Do you happen to know what the "inmem" wdb_open is for on mged.c:2826? I'm having a heck of a time figuring out what it does - I only see one use of .inmem in the Tcl code - ray.tcl - and I'm not really clear what it's trying to accomplish with that or if we need .inmem to do whatever it's trying to do... It goes back a long way in the repo - SVN r13946 in fact. I think that code might be why we've got two wdbp instances floating around in MGED.
Erik (Oct 05 2022 at 12:57):there used to be an in-memory concept of db way back to facilitate distributed raytracing, iirc. could it be related to that?
Sean (Oct 07 2022 at 04:52):Yeah, that one has quite a bit of history. Basically, it's an in-memory database where geometry can be loaded but everything is ephemeral (and crazy fast). If I remember right, Bob only hooked it into a couple things in mged, but the idea is that it's a copy of the database that only lives in memory so you can do prep on some geometry and you don't have to do it again, and there's no way to affect the .g by subsequent changes -- but you can still make changes.
Sean (Oct 07 2022 at 05:00):So in the case of ray.tcl, that's a routine used in a surprising number of places. It's how it queries what's under the mouse (by shooting a ray), which is one of the comb and primitive input selection methods, which is not just bound through in the tcl gui, but it's also hooked into classic mode through to the dm graphics window. By using inmem, prep only happens once.
Sean (Oct 07 2022 at 05:04):Note that the inmem doesn't really consume additional resources as it's an in-memory reopening of the same dbip. It's just tracked quite differently when changes are made. That's actually the same interface that's provided to ajem for dynamic geometry. The inmem is used for geometry changes that are desirable to be persisted to disk, and being in the inmem dbip, it can't even by accident down the road.
Daniel Rossberg (Dec 12 2022 at 23:19):I have a very bad feeling about https://github.com/BRL-CAD/brlcad/commit/abcba83f77babcccd0b9b7074037a424a2539c46. It breaks applications working with real in-memory databases, e.g. via the C++ interface. Fixing this would be a mess.
starseeker (Dec 13 2022 at 00:39):@Daniel Rossberg how does it break in-memory databases? I didn't remove that mode of operation, as far as I know... (note there are a lot of commits after that one related to that particular refactor as well - is current main broken?)
Daniel Rossberg (Dec 13 2022 at 04:58):After looking at my problem in the debugger, I have to admit, that I don't come so far to open a database.
What I try to do is open a database and getting its title. My last change was related to dbi_wdbp_inmem.
However, I don't even reach main() now. The program crashes in ON_wString::ReserveArray() during libged_init() with a segmentation fault.

That call stack is coming from OpenNURBS, so my first thought is that something about the new OpenNURBS version isn't playing nicely with the library initialization.

starseeker (Dec 13 2022 at 13:52):Does MGED work from that build on that machine?

Right.

MGED works.
Daniel Rossberg (Dec 13 2022 at 19:07):The point is, after some recompilations and tests, the error is gone. Was a clean build necessary? I saw this error on several machines. I'll have to look at them when I'm back.
