28 Mar 2025, Konstantin Olchanski, Info, mjsroot added
|
I need to look at histograms inside a ROOT file, but all the old ways for doing this no longer work. (in theory I can scp the ROOT file to
the computer I am sitting in front of, but this assumes I have a working ROOT there. anyhow it is pointless to fight this, all modern
packages are written to only work on the developer's laptop).

|
I had to change the ODBXX API: https://bitbucket.org/tmidas/midas/commits/273c4e434795453c0c6bceb46bac9a0d2d27db18
The old C API is case-insensitive, meaning db_find_key("name") returns a key "name" or "Name" or "NAME". We can discuss if this is good or bad, but that's |

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
that nobody nowhere seems to use db_delete_key() with follow_links set to TRUE.

I would handle this actually like symbolic links are handled under linux. If you delete a symbolic link, the link gets
detected and NOT the file the link is pointing to.

Today the way the history system is configured has changed. Whenever one adds new equipment
variables, the logger has to add that variable to the history system. Previously, this happened during
