in reply to DBIx::Class foreign key update woes

Hi Phil,
If you turn on SQL debugging (set DBIX_CLASS_STORAGE_DBI_DEBUG to true in your environment), you'll notice that the status object gets fetched when you first try to access ->descr, and isn't refetched when you just change a column entry in the check object. It would indeed be nice if that magically updated a related object, and I'll propose it.

In the meantime you can do either:

my $newstatus = $schema->resultset('Status')->find(2); $check->status($newstatus);
$check->update({status => 2}); $check->discard_changes();
It's not as pretty.. but it works.

    Thanks for the advice. It worked in my test.

    As for:

    It would indeed be nice if that magically updated a related object
    I don't need it to update that other object, just discard what it's holding so additional accesses will refetch it.

[Corion]: But yes, "who started this process" is interesting information :)
[tye]: no, I really believe that "login user" was added as a fundamental bit of info about each process in order to enhance the usefulness of auditing
[Corion]: Ah - if that information is saved in a file, then you could theoretically spam that file and confuse getlogin(). So, don't use it for authentication :)
[tye]: that is what getlogin() certainly *used* to do. I don't believe that is what it certainly should do.
[davido]: /var/run/utmp is 664 i think.
[tye]: Note that my "man getlogin" says that it uses stdin when it should use /dev/tty (calling a glibc bug). But that does not appear to be the case when I test it. But maybe Perl's getlogin() is not using glibc's getlogin().
[oiskuu]: well, run a strace and see what the getlogin does for you.... As I said. SELinux probably has those security labels. But not regular linux.
[tye]: for example, read https://unix. questions/146138/ loginuid-should-be -allowed-to-change -or-not-mutable-or -not
[tye]: I'm not using SELinux and it certainly appears to disagree with you. shrug
[tye]: Since you brought up /proc, oiskuu, I didn't see you respond to my suggestion of 'loginuid'. Does your /proc not have such?
