Geneve OS development discussion

[+InsaneMultitasker]

This topic is intended for discussing development of the Geneve 9640 operating system (known historically as MDOS).

 

Release history: 

 

Current development goals include: 

1. Identify the most recent, stable source code files; recreate bug fixes as necessary

2. Integrate the TIPI development and the 6.70/7.00 development 

3. Release an updated OS 

4. Release the updated source code

 

 

 

Updates:

A long-standing barrier to releasing the next stable OS was a disk IO corruption bug that has recently been identified and (seemingly) corrected.  (RESOLVED)

18 Jan 2021 - Combined 7.00 source base with TIPI support routines. SCSI Cache bug resolved.  Organized/cleaned up source and MAKE file structures. Built OS using HRD4000B w/ram hardrive routines.  v7.20

Can you fix cd to be more predictable. I can probably get some examples today if needed.

What is not predictable?

Yes, please.  There are some limitations to CD and other commands due to available space in that segment of the OS. (16 bytes free!)  We've removed DISKCOMPARE and DISKCOPY to free up some space in the command line interpreter, which might allow for some feature adds/corrections after a bit more analysis is completed.

It is predictable from what I see here.

 

CD does not check whether the path exists; this has always been the case. Would be nice if it did, but takes more time. On the right, the trailing slash should be removed. The bad thing is that DIR requires the trailing slash.

 

DIR MODULES will not deliver the contents

DIR MODULES\ does it

 

CD MODULES is OK

CD MODULES\ will fail.

[BeeryMiller]

In the example on the left, you got the device error because you typed "module", not "modules" with the latter being the correct folder name. And sorta along the lines with what was posted above, the trailing slash was after the directory name was converted to a period so that "modules" became "modules." which that folder does not exist either.

 

The CMD.exe window for Win10 allows one to:

 

cd down\ to go to C:\>DOWN

 

or

 

cd down. to go to C:\>DOWN

 

One route would require stripping a trailing "." or trailing "\" from the path request.  Another option is to strip and error report and revert back to the original path if an invalid entry is made similar to what a MS-DOS prompt would do.  

 

This is worth documenting as an improvement "as time permits" as it would likely require changes in a number of places in the CLI code for consistency sake across a number of commands impacted.

Happy Monday.

MDOS 7.00 code base integrated with our TIPI work from the past month.  

Took the time yesterday to delete/organize the source folders.

Compiled this morning using HRD4000B and ram hard drive support. 

Includes TIMODE2 alternative which frees up the dedicated MyWord ram (64k) for use.
