Release 93u+m/1.0.0-rc.1
We're nearly there! I intend to release ksh 93u+m/1.0.0 on 2022-08-01, precisely ten years after the last canonical 93u+ release. We have a week until then, so here's a release candidate. Please try as hard as you can to break it, and to help fix known bugs. As of this commit, the 1.0 branch is feature-frozen and will only get bugfixes. src/cmd/ksh93/fun/man: - Last-minute fix: .man.try_os_man(): do not look for arguments with / in section 1 and 8; this can cause false positives.

Announcing: KornShell 93u+m 1.0.0-beta.(unreleased)
|
||||
Announcing: KornShell 93u+m/1.0.0-rc.1
|
||||
https://github.com/ksh93/ksh
|
||||
|
||||
In May 2020, when every KornShell (ksh93) development project was
|
||||
abandoned, development was rebooted in a new fork based on the last
|
||||
stable AT&T version: ksh 93u+. This new fork is called ksh 93u+m as a
|
||||
permanent nod to its origin. We're restarting it at version 1.0. Seven
|
||||
months after the first beta, the second one is ready. Please test this
|
||||
second beta and report any bugs you find, or help us fix known bugs.
|
||||
[This is a release candidate. The announcement below is preliminary.]
|
||||
|
||||
We're now the default ksh93 in some OS distributions, at least Debian
|
||||
and Slackware! Even though we don't think it's stable release quality
|
||||
yet, the consensus seems to be that 93u+m is already much better than
|
||||
the last AT&T release.
|
||||
In May 2020, when every KornShell (ksh93) development project was abandoned,
|
||||
Martijn Dekker reboted development in a new fork based on the last stable
|
||||
AT&T version: ksh 93u+. He was soon joined by two main developers and a
|
||||
number of other contributors. This new fork is called ksh 93u+m as a
|
||||
permanent nod to its origin.
|
||||
|
||||
Now, more than two years, two beta versions, a number of enhancements, and
|
||||
rougly a thousand bugfixes later, *and* precisely ten years after the last
|
||||
canonical 93u+ release, version 93u+m/1.0.0 of the KornShell is released!
|
||||
|
||||
As an initial release, this still has known bugs; please do use this version,
|
||||
but also continue to test it. See TODO to help us fix the known bugs.

This repository is used to develop bugfixes

This is version 1.0.x of the 93u+m fork of the KornShell, including a
|

sizeable number of enhancements and roughly a thousand bugfixes compared
|
||||
to the last stable release (93u+ 2012-08-01) of

[ksh93](http://www.kornshell.com/),

|

|
||||
## Policy
|
||||
|
||||
1. Fixing bugs is main focus of the 1.x series.
|
||||
Major feature development is for future versions (2.x and up).
|
||||
2. No major rewrites. No refactoring code that is not fully understood.
|
||||
3. No changes in documented behaviour, except if required for compliance with the
|
||||
[POSIX shell language standard](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/contents.html)
|
||||
which David Korn [intended](http://www.kornshell.com/info/) for ksh to follow.
|
||||
4. No 100% bug compatibility. Broken and undocumented behaviour gets fixed.
|
||||
5. No bureaucracy, no formalities. Just fix it, or report it: create issues,
|
||||
send pull requests. Every interested party is invited to contribute.
|
||||
6. To help increase everyone's understanding of this code base, fixes and
|
||||
significant changes should be fully documented in commit messages.
|
||||
7. Code style varies somewhat in this historic code base.
|
||||
Your changes should match the style of the code surrounding them.
|
||||
Indent with tabs, assuming an 8-space tab width.
|
||||
Opening braces are on a line of their own, at the same indentation level
|
||||
as their corresponding closing brace.
|
||||
Comments always use `/*`...`*/`.
|
||||
8. Good judgment may override this policy.
|
||||
|
||||
## Why?
|
||||
|
||||
Between 2017 and 2020 there was an ultimately unsuccessful
|
||||
[attempt](https://github.com/att/ast/tree/2020.0.1)
|
||||
to breathe new life into the KornShell by extensively refactoring the last
|
||||
unstable AST beta version (93v-).
|
||||
While that ksh2020 effort is now abandoned and still has many critical bugs,
|
||||
it also had a lot of bugs fixed. More importantly, the AST issue tracker
|
||||
now contains a lot of documentation on how to fix those bugs, which made
|
||||
it possible to backport many of them to the last stable release instead.
|
||||
This ksh 93u+m reboot now incorporates many of these bugfixes,
|
||||
plus patches from
|
||||
[OpenSUSE](https://github.com/ksh93/ksh/wiki/Patch-Upstream-Report:-OpenSUSE),
|
||||
[Red Hat](https://github.com/ksh93/ksh/wiki/Patch-Upstream-Report:-Red-Hat),
|
||||
and
|
||||
[Solaris](https://github.com/ksh93/ksh/wiki/Patch-Upstream-Report:-Solaris),
|
||||
as well as many new fixes from the community
|
||||
([1](https://github.com/ksh93/ksh/pulls?q=is%3Apr+is%3Amerged),
|
||||
[2](https://github.com/ksh93/ksh/issues?q=is%3Aissue+is%3Aclosed+label%3Abug)).
|
||||
Though there are many
|
||||
[bugs left to fix](https://github.com/ksh93/ksh/issues),
|
||||
we are confident at this point that 93u+m is already the least buggy version
|
||||
of ksh93 ever released.
|
||||
As of late 2021, distributions such as Debian and Slackware have begun
|
||||
to package it as their default version of ksh93.
|
||||
For all fixes, see [the commit log](https://github.com/ksh93/ksh/commits/1.0).

______
|
||||
Fix regression test failures:
|
||||
|
||||
- There are some serious regression test failures on OpenBSD when ksh
|
||||
is compiled with AST vmalloc disabled, so the system standard malloc(3)
|
||||
is used. These probably represent real ksh93 bugs exposed by OpenBSD's
|
||||
security hardening mechanisms.

- Several known memory leaks have their tests disabled in tests/leaks.sh
|
||||
and are marked TODO. These need tracking down and fixing.

Fix currently known bugs affecting shell scripting. These are identified by
|
||||
their modernish IDs. For exact details, see code/comments in:

- BUG_BRACQUOT: shell quoting within bracket patterns has no effect. This
|
||||
bug means the '-' retains it special meaning of 'character range', and an
|
||||
initial ! (and, on some shells, ^) retains the meaning of negation, even
|
||||
in quoted strings within bracket patterns, including quoted variables.
|
||||
|
||||
- BUG_IFSGLOBS: In glob pattern matching (as in case or parameter
|
||||
substitution with # and %), if IFS starts with ? or * and the "$*"
|
||||
parameter expansion inserts any IFS separator characters, those characters
|
||||
are erroneously interpreted as wildcards when quoted "$*" is used as the
|
||||
glob pattern.
|
||||
"$*" does pattern matching if the first char of $IFS is a wildcard
