Added additional optional debug code. A version of gsh with the memory
checking debug code turned on is available as an exe file.
Lock and unlock the hash mutual exclusion key in when disposing of the
hash table.
Allow five digits rather than four when printing the process number in
the ps command.
Piping the output of a command into a non-executable file no longer
causes gsh to hang.
(PR#85, PR#86):
For login shells (command line starts with '-'),
If $PATH doesn't start with ':' or contain a space,
change all ":" to " ".
source /etc/glogin
source $HOME/glogin
$HOME/gshrc is sourced afterward for both login and non-login shells.
Don't the print number of hashed commands (from "rehash") until all
initialization is completed.
Only pass exported environment variables to child processes, and prevent child
processes from changing parent's environment.
A null command followed by a redirection of stdout, for example
> /tmp/list
would cause an error message "<garbage> not found" due to incorrect
setting of command buffer pointer.
Filename completion did not work following ">&" or ">" without a trailing
space.
Entabbed all the asm files, saving more than 36,000 bytes.
removed the need for p-string routines, so they were removed. Also
removed alloc256/free256 and associated data structures.
In removing calls, found instances in pwd & prefix commands and prompt
handler where current directory name was assumed to be < 256 characters;
recoded to use a flexible buffer size.
Updated and expanded mmdebug.asm routines that perform error checking on
memory management calls. Added macros ~NEW and ~DISPOSE that invoke either
the real or debug routines.
Fixed call to read $TERM variable's length to fix PR#81.
Removed echo of data when setting value of $< in expandvars (expand.asm).
The characters are echoed as they are typed and do not need to be reprinted
on stdout after carriage-return is typed.
Added error checking to the various flavors of prefix (just like cd):
- Verify 2nd parameter is a valid directory before setting.
- Verify 1st parameter < 32 before displaying or setting.
and link. However, it does not work yet and thus still needs work.
The *.asm files have had the following common changes:
- 'keep' lines were eliminated
- the 'mcopy' now takes the macro from the /obj/gno/bin/gsh
directory. This is in anticipation of having the macro
files generated from a single source file; there is a large
amount of duplication. For the moment, the makefile merely
copies the old macro files from the "M" directory to the
/obj/gno/bin/gsh directory.
- start each file with a dummy routine so that the source
code winds up in the *.o rather than the *.root file.
- added the 'setcom 60' directive; there were many source
lines that were otherwise getting truncated.
The makefile is a complete rewrite.
