emacs 29.2-2 (TEST)

[Ken Brown via Cygwin-announce]

The following packages have been uploaded to the Cygwin distribution as 
test releases.


* emacs-29.2-2
* emacs-common-29.2-2
* emacs-basic-29.2-2
* emacs-w32-29.2-2
* emacs-gtk-29.2-2
* emacs-lucid-29.2-2

Emacs is a powerful, customizable, self-documenting, modeless text 
editor.  Emacs contains special code editing features, a scripting 
language (elisp), and the capability to read mail, news, and more 
without leaving the editor.


This is the same as emacs-29.2-1, but it is built with the native 
compilation feature, which we explain briefly:


Many of the editing commands used in Emacs are defined in elisp 
libraries (*.el files).  To make Emacs run faster, these libraries are 
usually compiled to architecture-independent *.elc files, containing 
"byte-code" representations of the functions in the original files. 
These byte-code functions are interpreted by the Emacs "byte-code 
interpreter" when they are called.


Native compilation takes this one step further by using gcc to compile 
the elisp libraries to native shared libraries (like DLLs, but with an 
extension .eln instead of .dll).  This results in a substantial speed-up 
of Emacs.


Some of the .eln files are created at build time.  These are installed 
in a subdirectory of /usr/lib/emacs//native-lisp.  Others are 
created as needed and are stored by default in a subdirectory of 
~/.emacs.d/eln-cache.


The first few times you run Emacs, it might seem slow to start.  This is 
because it is compiling the elisp libraries that are needed for your 
init file (usually .emacs).  For the same reason, you might see 
occasional pauses the first time you use a command.  But otherwise you 
should see a noticeable speed-up of Emacs.


The .eln files have been built with ASLR[1] enabled.  The hope is that 
this eliminates the fork failures (and the need to rebase) that were 
present in some of the previous releases with native compilation.


If you experience a fork failure in spite of this, please make a bug 
report to the mailing list.  I'd also like to get feedback from people 
who try the test release for a month or so and don't have any problems.

Updated: dash 0.5.12-5

[Cygwin dash Co-Maintainer]

The following package has been upgraded in the Cygwin distribution:

* dash  0.5.12-5

DASH is a POSIX-compliant implementation of /bin/sh that aims to be
as small as possible. It does this without sacrificing speed where
possible. In fact, it is significantly faster than bash (the GNU
Bourne-Again SHell) for most tasks.

This package is being upgraded to current as an earlier release broke
existing function that may be relied on by some scripts, and the current
stable Cygwin release now supports locale dependent named character
class, equivalence class, and collating symbol filename patterns
required by this package release.

Add /bin/dash-VER-R link, plus version and date stamp on man page, as no
shell version info or query is available.

This release has been rebuilt re-enabling libc fnmatch and glob as
Cygwin/winsup now supports locale dependent named character class,
equivalence class, and collating symbol filename patterns like glibc,
and has been available for testing for some time.

Thanks to Andrey Repin for testing and bringing this to our attention,
Harald van Dijk on the dash list for pointing out the commit
responsible, and Corinna Vinschen for adding support for locale
dependent named character, equivalence class, and collating symbol
patterns to the Cygwin libc fnmatch and glob functions.
