|
Now that we use more and more C++, lack of "const" attribute on most midas functions is causing some
problems. I am now ready to commit changes to midas.h and odb.c that add the const attributes to ODB
access functions db_xxx(), i.e.

not again! I complained about this before, and I added a fix, but it must be broken again.

Have you actually been able to read /etc/passwd this way? I tested this on a few of our servers and it does not work. As far as I know, there is access
to files in resources, custom pages etc.

26 Jul 2013, Konstantin Olchanski, Bug Report, abort on buffer overflow in odb.c::merge_records()
|
The odb.c function merge_records() has a fixed size array of 10000 bytes to handle the data and it
aborts with an assert() if passed data bigger than that. It is called from db_create_record() which
already allocates a data buffer of correct size for it's operations.

|
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.

I would be in favor of not curing the symptoms, but fixing the cause of the problem. I guess you put the watchdog disable into mhist, right? Usually mhist
is called locally, so no mserver should be
involved. If not, I would prefer to propagate the watchdog disable to the mserver side as well, if that's not been done already. Actually I never would |

Have you updated to the current midas version? This issue has been fixed a while ago. Below

familiar situation, "too much data", you dice t or slice it, still too much. BTW, you can try to generate history
plot ODB entries from your program instead of from the history plot editor. K.O. |
