Stephan, why did you prohibit building mana.c without ROOT and HBOOK
support? I think such a configuration is valid and should be allowed.

The default C indentation style in xemacs uses "tab" characters, violating
the MIDAS coding convention. To disable this misfeature in xemacs (emacs
too?), put this incantation in your .xemacs/custom.el file:

Ok, I apologize. It's all ok. Thanks for clearifying. Concerning the assert's, it
would be nice to be able to disable them in release code. Under Windows, the
assert() is actually a macro which expands to zero if NDEBUG is defined. I

Sometimes (maybe after a client uncleanly exits?), I see phantom "open
records", for example:

I have seen the same behaviour and it annoys me, too. What I did in the past
is a "cleanup" in ODBEdit which removes these open records. I have soem code
in cm_watchdog(), which should take care of that. If a client is dead, it

20 Nov 2003, Stefan Ritt, , Implementation of db_check_record()
|
As Konstantin pointed out correctly, the db_create_record() call is pretty
heavy since it copies whole structures around the ODB. Therefore, it
should not used frequently. It might be that several problems are caused

I tried to reproduce the problem, but without success. So in case this happens
again, one should debug the code im cm_watchdog() next to the line

I see that MIDAS installs several set-uid-root programs into /usr/local/bin.
In this age and time of evil computer hackers, this is not a good idea and
we should Do Something (TM) about it. Here is my risk assessment:
