at the time, but on further reflection..." bucket with these changes.
1. Checking the media before frobbing the disks was a fine idea, and
I wish it could have worked, but that leads to a rather difficult
situation when you need to mount the media someplace and you're about
to:
a) Chroot away from your present root.
b) Newfs the root to be.
You're basically screwed since there's no place to stick the mount
point where it will be found following the newfs/chroot (and eliminating
the chroot in favor of just using the "root bias" feature would work
great for the distributions but not the pkg_add calls done by the
package installer).
2. Automatic timeout handling. I don't know why, but alarm() frequently
returns no residual even when the alarm didn't go off, which defies
the man page but hey, since when was that so unusual? Take out timeouts
but retain the code which temporarily replaces the SIGINT handler in
favor of a more media-specific handler. This way, at least, if it's hanging
you can at least whap it. I think the timeout code would have been losing
over *really slow* links anyway, so it's probably best that it go.
This should fix NFS, tape & CDROM installs again (serves me right for getting
complacent and using just the FTP installs in my testing).
section was a good thing, since it made it possible to detect media problems
*before* the installation started, but it also caused various things to
be mounted BEFORE the chroot() call, which definitely messes things up.
Fix this by detecting the pre-chroot() case and mounting into a subdir.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
1. Don't use the MSDOSFS code for accessing FreeBSD distribution data.
Use Robert Nordier's stand-alone DOS I/O library for the purpose.
It this works as well as Robert says it does, it should drastically reduce
(or even eliminate) our "I can't install from my DOS partition!" calls.
2. As a result of the above, go to stdio file descriptors for all
media types.
3. Taking advantage of #2, start using libftpio for FTP transfers instead
of maintaining our own parallel version of the FTP transfer code.
Yay! I ripped something out for a change!
#1 Submitted-By: Robert Nordier <rnordier@iafrica.com>
Make "selection bar" inverse video white-on-blue on color screens to avoid
it getting muddled up with popup dialogs.
Do disk selection in a more friendly fashion (for one thing, allow a
drive to be de-selected again if you change your mind).
Add a few strategic screen-saves to prevent corruption of screen contents
(thanks, Michael Elbel!).
I still have a _very very annoying_ display bug which occurs when a menu
item causes a submenu to be displayed - the screen repaints for the original
menu (which is restored upon return from the submenu) are off by about 4
characters. I've tried restoring the screen, the cursor position, you name
it - same deal. Grrrr! This commit is my first step in trying to get someone
else to help me look into this one since I'm just tearing my hair out at this
point!
multi part stuff centralized.
The final check is backwards or something so it always said it failed,
even it it didn't.
Fixed tcpip address check to not be stupid, 10.0.255.1 is legal.
