There was a request on IRC to update the ansible package.  I've had a
quick look, the tentative result is on the playground branch:

https://cygwin.com/git-cygwin-packages?p=git/cygwin-packages/ansible.git;a=shortlog;h=refs/heads/playground

As mentioned by Yaakov, I switched over to ansible-core, updated the
patches and made some changes so that th CI would have a chance to build
the package.

Some of the necessary packages are missing for python39 so I had to keep
this at python37 and one (python37-straight.plugin) doesn't currently
exist at all.  


Hi Achim,

which are missing for python39 other than paramiko ?
I built the python3x-straight.plugin and uploaded it.

Skipping the doc ansible builds with python39

The latter may not actually be needed anymore, but the

package build doesn't work anyway.  Someone with more knowledge of
python would need to look at where exactly the problem is (the
"packaging" module seems to be missing even though it's in the
BUILD_REQUIRES) and provide a fix.



Documentation requires "Tools for building the Ansible Distribution"
https://pypi.org/project/antsibull/

so I think we need only for python39 and not for all versions
ok ?

To summarize, I am not sure that the original issue
has anything to do with 2nd monitor,
nor any changes in the Xorg-sources.

In _my_ case it was a matter of how the Xserver was
started, and what dpi settings it was started with.

If server was started with incorrect dpi settings, it
would cause problems with some Xclients having mangled or
trunated characters at the bottom of their windows.

For me, it was a matter of ensuring that my modified
startX script was called instead of the stock script, as
my modified script checks the windows DPI setting on startup.

That said -- on Win10 it could be further complicated
by having multiple monitors with different dpi settings.  I seem
to remember win10 having some provision for attaching a
different DPI value to different monitors.

That's likely to create a problem in 'X', since AFAIK,
X hasn't been enhanced to allow different DPI values on
different "screens".

Possible fit?

[Tom Sampson]

Hi Kerri,

My name is Tom Sampson, I am a 33-year franchising veteran where I have 
operated as a single-unit owner, master developer, and franchise development 
executive for some of the most successful brands in the game.

Since then, I have become one of the top franchise consultants in the country, 
helping hundreds of individuals take control of their life by finding the right 
franchise for them.

I was looking at your background and work experience with Concept Development, 
Inc. and thought you might be a good fit for exploring franchise ownership.

Here is a bit more about me:

  *   I specialize in helping individuals like yourself examine “manager-run” 
franchises – concepts that specifically allow them to keep their day job while 
starting a business.
  *   I also work with clients looking to exit corporate America and achieve 
their dream of running their own business full time.
  *   And finally, my services are provided at no cost to you, while you stand 
to benefit from my unique perspective derived from 33+ years of experience as 
both a franchise owner and developer.

I have worked with a multitude of business leaders, like yourself, find their 
true “balance” that brings both meaning and satisfaction to both business and 
personal pursuits.  Together, we will work together to find your perfect match 
among the thousands of franchises available in the U.S.

Please let me know if you are interested in speaking or learning more.

Thanks,

Tom Sampson

[ANNOUNCEMENT] Updated: openldap-2.6.1-1

[Achim Gratz]

The openldap package in Cygwin has been updated to the latest upstream
version 2.6.1.

https://www.openldap.org/software/release/changes.html


Notes
=

Upstream has removed the two database backends that worked at least
partially on Cygwin.  Since they don't support Cygwin (and indeed ponder
to drop the Win32 port at some point), the openldap-server package has
been removed.

Upstream has changed the SONAME versioning scheme after 17 years to
align with the fact that actually all 2.x releases were ABI compatible
and not changing ABI with each release.  Packages for libopenldap2_4_2
and libopenldap2_5_0 are thus provided to replace the previously
separate libraries for the older release versions (so older packages are
automatically using the newer library).  Packages depending on these
need not be recompiled, but package maintainers should check that any
rebuilt packages are using the new libopenldap2 package as a dependency.

      (Marco Atzeri via Cygwin-announce)

This release updates Zstandard to the latest upstream version, which is
a maintenance release with minor performance improvements and bugfixes.


Zstandard, or zstd as short version, is a fast lossless compression
algorithm, targeting real-time compression scenarios at zlib-level and
better compression ratios.

http://www.zstd.net/


Besides a standalone compression tool, development headers and a library
with comprehensive API are available both for Cygwin native applications
and cross-compilation toolchains in the following sub-packages:

libzstd-devel-1.5.2-1
libzstd1-1.5.2-1
mingw64-i686-zstd-1.5.2-1
mingw64-x86_64-zstd-1.5.2-1


Notes
-

This version is compiled with support for GZip, LZ4 and Xz compression
and all libraries are built with MT capability.  Support for legacy
formats from ZStandard versions before 1.0 has been removed.

The openldap package in Cygwin has been updated to the latest upstream
version 2.5.11 (a minor bugfix release).

Notes
=

The 2.5.x version branch changes the library ABI.  Packages linked
against an earlier libldap ABI need to be recompiled to use this new
version.

Upstream has removed the two database backends that worked at least
partially on Cygwin.  Since they don't support Cygwin (and indeed might
drop the Win32 port at some point), the openldap-server package has been
removed.

This is likely tha last 2.5.x release for Cygwin, the next Cygwin
release will likely be 2.6.1.  The release notes linked to below point
to the 2.6.1 version, which was released upstream in parallel.

It can also preserve existing comment in unserialization/
serialization steps, making it a convenient format to store
user input files.

CYGWIN CHANGES

As python2 is no longer supported

https://devguide.python.org/devcycle/#end-of-life-branches

the package are updated to include postinstall script that
use "alternatives" to define for

  /usr/bin/python

  /usr/bin/python3
  /usr/bin/idle3
  /usr/bin/pydoc3

a default to the highest package available.

$ alternatives --display python
python - status is auto.
 link currently points to /usr/bin/python3.9

/usr/bin/python3.6 - priority 36
/usr/bin/python3.7 - priority 37
/usr/bin/python3.8 - priority 38
/usr/bin/python3.9 - priority 39
Current `best' version is /usr/bin/python3.9.

The following link are not provided anymore.
/usr/bin/idle
/usr/bin/pydoc

Rationale:
https://www.python.org/dev/peps/pep-0394/
In other systems as Debian
/usr/bin/python is discouraged.

As on Cygwin we have still several third packages depending on
python2, the usage of alternatives should allow to manage
until all are updated to python3

DESCRIPTION
Python is a programming language that lets you work quickly
and integrate systems more effectively.
Python is powerful... and fast; plays well with others;
runs everywhere; is friendly & easy to learn; is Open.

Re: python-numpy (1.22.0-1) can't be imported

[Masamichi Hosoda]

> If I understand correctly, I've found the root cause of the issue.
> I've sent a pull request to numpy.
> https://github.com/numpy/numpy/pull/20874

A question is asked by NumPy if there is documentation
on the Cygwin package's Cython behavior.
https://github.com/numpy/numpy/pull/20874#issuecomment-1019442058

Does such a document exist?

One of the causes of this issue is a patch
in Cygwin's python-cython package like the one below.
It removes the `__declspec(dllexport)` attribute
from the symbols to be exported.

On the other hand, if you install Cython
by pip without using the Cygwin package,
the exported symbols have the `__declspec(dllexport)` attribute
because the patch has not been applied.

What is the purpose of removing the `__declspec(dllexport)` attribute
in this patch?
Is this to make the modules using Cython
without considering the Cygwin environment,
the module does not have the `__declspec(dllexport)` attribute
like Linux environment, works correctly?
