C. Masloch c0b8aa2bf4 task: return Invalid format on empty executable (fixes #70) 2022-05-21 23:22:08 -04:00
C. Masloch b562983222 config: add the CONFIG, ALTCONFIG, and OLDCONFIG kernel command line commands 
CONFIG takes precedence and is by default initialised
to the empty string, that is, skipped. ALTCONFIG is
used to specify the 'alternative' filename and defaults
to fdconfig.sys. Finally, OLDCONFIG defaults to the
config.sys filename.

C. Masloch 4377a257e0 kernel, main: read kernel command line into init segment buffer 
The protocol for this extension is based on what lDebug
already does given the PROTOCOL=FREEDOS with the switch
CMDLINE=1 (which was originally defined for the lDOS and
RxDOS load protocols). Therefore the stack frame mirrors
that of the lDOS protocol.

C. Masloch 49733547f1 kernel, main: add debugger_present variable and skip ints 0, 1, 3, 6 
Also adds a CheckDebugger byte to the CONFIG block and
support for reading and writing this setting in the
SYS CONFIG program. Default is 0 (no check assume absent).

C. Masloch 7ff6c06814 kernel: copy CONFIG block from UPX help data early in kernel.asm 
Here we depend on the signal instruction that is patched
by exeflat to indicate whether we were compressed. This
replaces the prior check that detected the UPX help data
solely by checking the CONFIG signature at 05E2h.

C. Masloch b7345d9165 main: note that we want to set int 31h segment to DOS DS 
This commit does not change the behaviour of the code
as it already did the right thing. However, it notes
that that should happen. (This is DR DOS compatible.
For example, SHSUCDX depends on DR DOS setting this
segment so that it can keep track of the DOS DS
across it being relocated. We do not yet relocate it
but keeping a reference here is still useful.)

Andrew Bird 4b3f7e0088 int2f: make share_open_check() to accept FAR 
Fixes problem with GCC-ia16 compiled share not allowing open of files.
It seems that the TCC 2.01 compiled version was fortunate in that DS
happened to be correct when the interrupt was called, but this was
not the case for the GCC ia16 compiled version.

It's an analogue of this patch by @stsp for FDPP.

Andrew Bird 5b9e8fedcc dosfns: Check share table before delete/rename 
Delete and Rename should not be able to remove an open file,
so check share's open file table first. Behaviour is now identical
to MS-DOS 6.22.

Note: Uses a new subfunction of the FreeDOS share multiplex
      interrupt int2f/0x10a6 called is_file_open()

A similar patch was applied to FDPP at
https://github.com/dosemu2/fdpp/commit/691721f1

Fixes dosemu2 tests:
  test_fat_ds3_share_open_rename_fcb
  test_fat_ds3_share_open_rename_ds2
