2.11BSD TOP and long usernames

[Heinz-Bernd Eggenstein]

Hi all,

The top code has seen quite a bit of patching lately, e.g. to deal with long host names corrupting the table structure. But I think there is a similar problem with "long" user names.

The current version (as of patch 490) prints user names using a "%-7s" format string, so left aligned filled with spaces to a width of at least 7 characters (but not truncating the string).

So even usernames with length 8 will break the table structure. 

The next table column to the right is that for the scheduling priority which gets 5 characters which seems excessive, the ps command uses a width of 4 only (including a space for column separation in both cases).

So could we perhaps extend the uname column to 8 characters and shorten the PRI column to 4?

We could then truncate user names that are longer than 8 characters to 7 followed by a "+" as is done in many modern versions of top and ps ?

Something along the enclosed patch perhaps?

Cheers

I believe you can submit the bug report, and probably your patch, to bu...@2bsd.com using the template found at /usr/share/misc/bugformat.

There is also a 'sendbug' script on the 2.11BSD system that will fire up the default editor with the template loaded and once it is filled out will presumably mail it to bu...@2bsd.com. But I don't know if that is likely to work with all that's involved in sending email these days. Might be easier to just copy/paste the template into your regular email client.

Yeah I didn't try to get sending email from within 2.11BSD on the PiDP11 work, but it's on my list :-) . I wanted others to check this first, e.g, I'm a bit unsure what the minimum and maximum values from the PRI(ority) field are.

Nah. I'll pick it up and get it in there.

Cool, thanks! I guess this can wait until there are other issues fixed to form a critical mass for a new patch.

Ohhhhh sh*t, there was an embarrassing typo in my patch. Sorry I
wasn't quite myself lately (one of my two cats and dear friend for 16
years just had to be sent over the rainbow bridge),

So here is what I think might work, but someone really needs to have a
2nd look at it. I still see some corruption of the top display
especially under heavy load (as some stray numbers in the bottom right
corner), but I think this has nothing to do with my patch but must be
a preexisting problem.
