05 May 2025, Konstantin Olchanski, Info, db_delete_key(TRUE)
|
I was working on an odb corruption crash inside db_delete_key() and I noticed
that I did not test db_delete_key() with follow_links set to TRUE. Then I noticed

05 May 2025, Konstantin Olchanski, Bug Report, abort and core dump in cm_disconnect_experiment()
|
I noticed that some programs like mhist, if they take too long, there is an abort and core dump at the very end. This is because they forgot to
set/disable the watchdog timeout, and they got remove from odb and from the SYSMSG event buffer.

23 Jul 2025, Konstantin Olchanski, Suggestion, K.O.'s guide to new C/C++ data types
|
Over the last 10 years, the traditional C/C++ data types have been
displaced by a hodgepodge of new data types that promise portability
and generate useful (and not so useful) warnings, for example:
