forward them on to subprocesses. nice when running a subprocess in
a display window to allow the user to kill the subprocess w/o nuking
sysinst itself. add handling for QUIT, which gets handled the same
as intr. add handling for HUP which just cleans up. More signals
should be handled.
use stdscr's maxx and maxy to set up the message window rather than hard
coding 78 and 22, respectively. The latter, combined with large messages
and a relatively small screen (and perhaps badly-placed menus), would seem
to cause the SEGVs reported in PR#7806. (For certain window sizes, the
menu system would reject the menus as too small, but for others sysinst
would just crash.)
be called. it'd cleanup() then exit(). however, cleanup() is scheduled
to run at exit via atexit(). This means that it gets run twice, and
this causes confusion for things like endwin(). The end result is
that rather than actually exiting and printing the "sysinst terminated"
message, after one control-c it looks like it's still sitting at the
last screen you were viewing even though it's actually at a shell prompt.
squelch the cleanup() in the SIGINTR handler to avoid this problem.
* while here, nuke the annoying space before the "sysinst terminated."
message. it looks bad, and serves no purpose.
- Make all the functions called from do_install() return an error code,
so that we can abort install if something went wrong.
- Add a 'errstr' argument to run_prog(), which if not NULL is displayed
with msg_printf() and followed by process_menu(MENU_ok) if the command fail.
Used to warn the user that the current action is aborted.
- in a few places use msg_display() or msg_printf() rather than printf.
It seems that stdout/stderr are not always pointing to the active curses
window.
- garbage-collecd unused messages, add a few new one (error handling).
XXX only tested on i386. Other md parts should be tested as well.
* Use structures, not 2-dimensional arrays..
* Use the DIOCGDEFLABEL ioctl to get the disk information,
to avoid confusion with (older) labels.
* Don't ever call fdisk for partitioning. This was the
source of much confusion.
* For the i386, use the BIOS geometry information passed by
the bootblocks.
Lots of things left to do, but it's a start.
Scripting and logging functionality for sysinst.
Child programs are run in a "display window" so you can actually see what
they did before the screen flashes back and you loose it all.
Lots of curses fixups. Removed nasty endwins that mangled the tty upon
rentry.
Change the yes/no box to accept Y or N, and not require cursor motion to
decide one or the other.
Perform curses redraws when doing things that could cause the kernel to
spew printfs onto your screen.
* Add mount_with_unwind() that adds mountpoint to a LIFO queue
of mountpoints to undo on error. Use in target_mount().
* Add unwind_mounts() which traverses the LIFO queue and unmounts
filesystems, silently ignoring errors.
* create toplevel() function which displays banner message and
calls unwind_mounts().
* change toplevel menu to call toplevel() instead of inline banner.
Where to do unwinds needs more thought. Perhaps we should only unwind
if an upgrade or install appears unsuccessful, so after a successful
install, the target is mounted (e.g., for upgrading /etc/rc.conf).
all pathname-on-server related definitions to MI code, since they are now
defined to be consistent across all platforms. Also, nuke the "rels" global,
since release numbers are now always specified in "long form", i.e. 1.3A
vs. 13A.
- Added -r rel flag to change the release tag on the tar files.
- Added Usage
- Fixed a menu bug (missing exit)
- Made target_expand available to all functions to produce correct
file names.
parallel development. i386 version about 90% complete. pc532 version
just started, other architectures later in coordination with portmasters.
This is a curses based, menu driven installation program.
Better error checking is needed.
