|
|
Completed items are reported in file UpdateLog.
|
|
|
|
|
|
Determine why gsh gets SIGTTIN (background read attempted signal) when
|
|
it executes a very quickly executing child program. Currently gsh
|
|
quits in order to avoid waiting forever, but that may not always be a
|
|
good strategy.
|
|
|
|
Rather than have each built-in command always be either forked or
|
|
non-forked, check dynamically and only fork when it's really necessary
|
|
(background or piped). Something like this:
|
|
If process is in background (&) or piped (|), then fork.
|
|
Otherwise: if redirecting I/O, then
|
|
copy file descriptor(s)
|
|
open new stdin, stdout, and/or stderr
|
|
Execute process.
|
|
If I/O was redirected, then
|
|
close redirected file(s)
|
|
reconnect stdin, stdout, and/or stderr
|
|
Note: routine "command" sets srcfile and dstfile.
|
|
|
|
Identify limits built into gsh and how they can be changed; for example,
|
|
command line cannot expand to > 1024 characters.
|
|
|
|
When a background process finishes and there's text in the input buffer,
|
|
the next keypress correctly reprints the edit line but the key itself does
|
|
not get put in the buffer.
|
|
|
|
Gsh requires the v2.0.4 ltermcap to link. A new version of the termcap
|
|
library is proposed for GNO v2.0.6, and gsh may require updates.
|
|
|
|
job control monitor for defunct processes when waiting.
|
|
|
|
job control needs to save tty information.
|
|
|
|
Allow ~user construct (call routines to get user's home directory)
|
|
|
|
recursive aliases.
|
|
|
|
In expandvars (expand.asm):
|
|
Add error checking if out buf gets too big (> 1024)
|
|
Get rid of fixed buffers
|
|
|
|
[ -- below this line...probably never will be done -- ]
|
|
|
|
write new memory management.
|
|
|
|
coolish handling of setdebug by editor.
|
|
|
|
echo should use octal and hex \12 is dec, \012 is octal, \x12 is hex.
|
|
|
|
write history expansion.
