Sorry for the delay in replying. I'm hip-deep in deflate
compression-side logic (implementing the rest of gzip, somebody poked me
and said they need it now), and the vmstat command is a can of worms for me.
My most recent cleanup pass on vmstat was:
http://lists.landley.net/pipermail/toybox-landley.net/2013-December/001513.html
And that description ends with the fact that I have no CLUE how several
of those fields are calculated. What we're doing doesn't match what
other implementations are doing, and there's no standard or
documentation on what it _should_ be. (Trying to find that sort of thing
out is a giant timesink. Gotta do it eventually, but there are higher
priority todo items at present, at least until somebody pokes me and
says "I need X now". :)
Yes, there are some "pending" commands that aren't in the "pending"
directory, the list of them is in toys/pending/README. Initially I just
had a list of commands needing cleanup, but it kept getting longer as
contributions came in faster than I could clean them up, and I added
toys/pending when the list got too long to manage. I've got it down to
11 commands and one lib file, and I keep meaning to just properly review
and clean up that old list rather than try to explain it to people, but
the remaining issues in those commands tend to be nontrivial (or I'd
have fixed them by now). Sometimes, simple is a destination you go
through a lot of complexity to reach...
Anyway, your bug is easy to test and thus easy to fix, but I'd actually
fix it in a different way because:
1) I'm uncomfortable assuming INT_MAX will never be reached. (Yeah,
almost certainly true in this case but INT_MAX != infinity and I don't
want to get into the habit.)
2) Minor bug with "./vmstat 2 3" where it has the 2 second pause right
before exiting. It'snot going to produce more output, so it should just
have the pause twice.
Did the fix I just checked in work for you?
