MH-MiNT 1.12h1
I've put up a new re-sync patch...
To put a provisional end to that silly name "discussion": As you can
see from this message's subject header, I've chosen to go with
Torsten's suggestion, at least for the time being. I hope you like
the new greeting message that's printed when MiNT (or MH-MiNT, if you
like) starts up (I haven't yet seen this message, I just built it in a
few minutes ago :-).
(BTW, I don't understand why most people seem to like non-intuitive
case-sensitive abbrevations... Why hasn't anyone come up with a short
and simple new name? :-)
As for meeting the MiNT license: I've changed the name and the
greeting message, I've listed all changes in a new file Changes.MH,
and I've put a comment in every changed file pointing to Changes.MH.
(Changes.MH lists all changes in reverse order; I've set up an
automatism that updates this file whenever I check in new changes.)
Thanks to Eric, Bjarne and Juergen for reviewing the differences to
1.11h3 I posted!
David's Lattice diffs just came a few seconds to late to be included
in this release.
After my .sig are the last few commit messages. They also include
previous changes folded in from 1.10h3. I hope I haven't missed
anything; feel free to review this list of changes.
Now available via ftp from ftp.inf.tu-dresden.de:
pub/atari/Mint/Kernel/mint-1.12-1.12h1-diffs.gz

On all Un*x systems I know, the werase character deletes the

and the previous word. In MiNT the word was only deleted if the cursor
was at the end of the word. I fixed this behaviour to be like Un*x.

restore the old check whether the size of a block matches the
requested size.
The code I fixed always checks for enough size to save the requested
memory plus the size of a block header, however this made the test
whether to unlink the block completly always fail. I restored the old
behaviour (which has worked for me in (a fixed) MiNT 1.09 for around
half a year without problems).

Message-Id: <9408231007.AA20275@rio.heidelbg.ibm.com>
- Changed f_chown, so a user can change the group of a file
to any of his supplementary groups, not only the effective group id.
Also added one more "posix"ism; if the file has set-uid or set-gid bit
set these bits are reset when f_chown is called by a non-root process
and the file is not a directory.
- Added BSD-like setgid and sticky bit
semantics for directories. Setgid semantics are implemented in do_open
and d_mkdir, so that any file or directory that is created in a
directory whose setgid bit is on, will be created with a group id
equal to that of the directory instead of the process' effective group
id. (This complements nicely the existence of supplementary groups
:-). Sticky bit semantics prevent any non-root process from deleting a
file or directory in a directory with sticky bit on, which the process
doesn't own. This is implemented d_delete, f_delete and f_rename(!).
As a side effect I modified the dir_access routine, so that it returns
the file mode bits in a (new) third parameter.

cookie.h, dos.c, main.c, makefile, proto.h, cookie.c (new):
From: evanlang@uss.lonestar.org (Evan Langlois)
Subject: mint 1.11 patch
Message-Id: <m0qYtQm-0004pkC@uss.lonestar.org>
added the s_cookie() call for reading system cookie
information. This is mainly the cookie jar, but also the
200Hz timer, and possibly other info if you decide to support
it. This code is a bit buggy in that it needs a proper sanity
check (see code) and the jar resizing doesn't work. The code
worked with Malloc() before I put it in the kernel, but I
guess I'm not allocating the new memory region properly.
Main.c and cookie.h were changed for readability - no more
treating cookie tags as a string. Cookie.h lists the values
for the cookies - and could be expanded into a "master
listing" of cookies.
prefixed cookie definitions in cookie.h with "COOKIE_" --hohmuth
added prototypes for local functions in cookie.c --hohmuth

changed DIRSEP so that a Unix slash is accepted by all file
systems except TOSFS (and maybe other NO_PARSE systems). This
has been well tested - it makes things easier with no side effects

Subject: mint 1.11 patch
and added a new flag to all file systems
included in the kernel except unifs and tosfs. These changes
are the file cookie cache. It speeds lookup operations to twice
the speed (on my system anyway). The flag mentioned above tells
the system not to cache the file cookies for that system (I found
that a background top could eat up lots of cookies in the proc
filesystem, so I decided not to cache /proc, /pipe, /dev, or
/shm). It doesn't cache NO_PARSE systems either. Everything for
this is ifdef'd. You must compile with -DFCOOKIE_CACHE to use
this code.
#define FCOOKIE_CACHE in mint.h, making this the default --hohmuth
