 18 Feb 2008, Konstantin Olchanski, Bug Report, potential memory corruption in odb,c:extract_key()
|
It looks like ODB function extract_key() will overwrite the array pointed to by "key_name" if given an odb
path with very long names (as seems to happen when redirection explodes in the Safari web browser, via
db_get_value(TRUE) via mhttpd "start program" button). All callers of this function seem to provide 256

Hi all,
I'm currently trying to see if I can speed up polling in a frontend I'm testing.

Something must be wrong on your side. If you take the example frontend under

20 Mar 2025, Konstantin Olchanski, Bug Report, please fix mscb compiler warning

I am getting a scary compiler warning from MSCB code. I generally avoid touching MSCB code because I have no MSCB hardware to test it, so I am
asking the persons unnamed who wrote this code to fix it. Stock g++ on Ubuntu LTS 24.04. Thanks in advance!

I hopefully fixed the waring (narrowing down from size_t to int). Please double check with your compiler.

Nope, it turns out complain is about the read() size argument, they really really really want it to be
