Odd trailing character on version string #87

Closed andrewbird closed 9 months ago

andrewbird commented 9 months ago

Not sure what the last character signifies on ver /r comcom64 string. Screenshot_2024-03-08_18-46-27

I'm in the UK, so I expect my codepage is 858

stsp commented 9 months ago

I think its already fixed by https://github.com/dosemu2/comcom64/commit/fc0b874a6e8f23f5fc90901afc834cd4b8003d84

stsp commented 9 months ago

But I am not sure as I am using a different stub where that problem doesn't trigger at all.

andrewbird commented 9 months ago

Thanks, I'll check that out as soon as the PPA gets updated.

andrewbird commented 9 months ago

PPA package was updated today and now the odd character is gone, thanks!

stsp commented 9 months ago

Cool! I actually forced the rebuild for you, because I want to replace the stub with a new one, and your ticket was holding that process. :)

stsp commented 9 months ago

Btw, as you are the last user of the old stub, could you please see the mem output? I suspect the old stub consumed much more than the new one will.

andrewbird commented 9 months ago

Is that freedos mem, as I'll have to install it?

stsp commented 9 months ago

No one have written built-in mem yet, so insfdusr (given that you have install-freedos scripts installed).

Isn't that more memory used?

stsp commented 8 months ago

Well, conventional memory is used only by 3K, and not by command.com. But UMB... Yes, seems some excessive use is here.

stsp commented 8 months ago

I think if you update now, the numbers would be different.

Mmm, actually I only got an FDPP update and not comcom, so the numbers didn't change.

stsp commented 8 months ago

There is something wrong on LP: the arm64 builds are now waiting for 6-10 hours before being built, but the x86_64 builds process rapidly. But maybe the x86_64 builds are not published w/o arm64 ones? Lets wait a bit more... :(

Wow! a00c 256 (0K) COMMAND program

Yes, I was always wondering why the prot-mode program consumes the conventional memory in a large quantities... 0K is quite an answer: it shouldn't. :)
