RFH: mksh development

Posted 2 days ago by t...@mirbsd.org (MirOS Developer tg)

mksh development is mostly done by
a single person, "the mksh team" (as seen on Ubuntu forums, out of all
places!), a.k.a. me, myself and I. Sometimes, actual users report bugs
or even send in patches. I keep track of oksh's ... [More] development as well, of
course. But there are times I would like to get feedback on issues from other people
working on pdksh or its descendants. I mailed, for that specific issue
in question, the Debian developer who created the original patch which
addressed the scenario except for a corner case (interestingly, as the
world is small, discovered in a Debian(!) init script from a package
maintained by aforementioned formorer, on a DomU running Lenny at work - don't underestimate the effect
of synergy) but would really like to talk to some of the OpenBSD devs
about it; they mostly know what they're doing, even if I worked on ksh
for longer than most of them, many eyes do help, and most of the time
I do not know what I'm doing XD

[Update] There's also the issue of inter-(POSIX-compatible)-shell
discussion. For instance, "set -u" vs "$@", which has come up in Debian #522255 because GNU
bash4 decided to switch to the behaviour used by the Bourne shell
(from V7 to SVR4.2), all Korn shells, ash and its descendents (like
posh) except dash, to not treat it specially. (Funny too how they
suggest 「${@:-}」 or 「${@:+}」 instead of 「${1+"$@"}」 (from the
GNU(!) autoconf texinfo documentation) as replacements.) Oh well,
zsh also behaves like bash2/3 and dash, but then, it's not even a
POSIX compatible shell. *sigh* Now I wonder what AT&T ksh93 will
do and a
confirmation if it's indeed being forcibly changed by POSIX (IMHO,
they could at least "agree to disagree", like they usually do, and make
it vendor defined, so that scripts could not depend on it - "set -u" is
something I don't use anyway).

So if you're interested in the further development of MirBSD, The
MirOS Project, one of its subprojects, such as The MirPorts Framework,
mksh(1), MirMake, even jupp-2.8 or jupp-3.x, please talk to me.

[Update] Do the same for POSIX compatible shell discussion, if you
are going to take mksh, its goals, needs and history seriously. (Yes,
it also has bugs, like a non-recursive parser troubling COMSUBs, but
they may be fixed long-term, especially if people contribute. Ideas,
at the very least.)

Thanks in advance. [Less]

mksh R38c released

Posted 29 days ago by t...@mirbsd.org (MirOS Developer tg)

The MirBSD Korn Shell R38c has been
released. This is one of the everyone-should-upgrade versions because
of the fixes for crashes and the
likes. Read the online manual page in HTML – mksh(1) – or as PDF for printing.

mksh R38 released

Posted about 1 month ago by t...@mirbsd.org (MirOS Developer tg)

The MirBSD Korn Shell R38b has been
released. It adds portability to QNX 6.4, a built-in base64 decoder and
encoder written in mksh itself, and most importantly fixes a regression
introduced in R38 causing memory corruption.

mksh user feedback appreciated

Posted about 1 month ago by t...@mirbsd.org (MirOS Developer tg)

With another mksh release out, and
the first feedback (actually a patch with explanation – naaina
ported it to the newly released QNX 6.4, 10x) already in, I would like
to request user feedback if mksh compiles okay for them, the ... [More] regression
test suite results, and if it does its job – especially on the
more obscure platforms. Current plans for R36b are mere portability and
bug fixes, and maybe some more of the Syllable, Plan 9 or Haiku issues
touched if someone does it.

On the other hand, I'm really glad I get feedback, even patches from
people I've never heard of beforehand, which even touch documentation
as it should be. One had the luck of adding a feature that had been,
independently, requested in IRC mere
days beforehand. You're welcome ;)

Let me plug a link to the fine manual page mksh(1) or its PDF version.

Thanks to all users as well, we cracked the 100 in Debian popcon a
few days ago (102), even though it's down a tad right now, to 94.

Plans are to get promoted to Arch Linux Community from AUR, included
into Mac OSX, Minix, pkgsrc® (as bootstrap shell) and QNX by default,
and the usual world domination in general. Hey, I'm fixing dietlibc
bugs on Launchpad now, so low I've sunk, so gimme some rest. [Less]

mksh R38 released

Posted about 1 month ago by t...@mirbsd.org (MirOS Developer tg)

The MirBSD Korn Shell R38 has been
released. Most prominently, our developer wbx@ (Waldemar Brodkorb) has
suggested to allow for expansion of “!string” style lines, and several
things (string lengths, substring expansion) have been made more aware
of UTF-8. Grab it as long as it’s hot!
