Not to state the obvious, but this means that the Microsoft antivirus
program prevented it from running.

Exclude it.

RE: [ANNOUNCEMENT] Updated: setup (2.917)

2022-01-24 Thread Buchbinder, Barry (NIH/NIAID) [E] via Cygwin
I cannot run setup 2.917.

When trying to start setup-x86_64 -n -B under cmd.exe or by cygstart under
bash, I get the following error message.

Unable to start 'C:\cygwin\usr\local\bin\setup-x86_64.exe': The operating
system denied access to the specified file.

Adding -w to the command line does not help.

Opening direct from Chrome gets the following error message.

Windows protected your PC
Microsoft Defender SmartScreen prevented an unrecognized app from starting.
Running this app might put your PC at risk.

Setup 2.915 still works fine.

Thanks

- Barry

[ANNOUNCEMENT] Updated: setup (2.917)

2022-01-24 Thread Jon Turney

A new version of Setup (2.917) has been uploaded to:

 https://cygwin.com/setup-x86_64.exe  (64 bit version)
 https://cygwin.com/setup-x86.exe (32 bit version)

Changes compared to 2.915:

- Show a warning if running on a deprecated Windows version

Support for:
- Windows 6.0 (Windows Vista, Windows Server 2008)
- 32-bit Windows (including WoW64)
in Cygwin is deprecated and will be removed in the next major version, 
sometime this year.


This warning can be disabled with the '--no-warn-deprecated-windows' or 
'-w' option, or using a "In the future, do not show me this dialogue 
box" checkbox.


- Fix setup silently exiting if elevated and 'CYGWIN=winsymlinks:lnk' is 
in the environment (by ignoring that environment variable)

  Addresses: https://cygwin.com/pipermail/cygwin/2022-January/250523.html

- Fix creating bogus versions of obsoleted packages (under certain 
specific circumstances), which then fail to download because they don't 
exist!

  Addresses: https://cygwin.com/pipermail/cygwin/2022-January/250604.html

For instructions on obtaining and building the source code for setup, 
see https://sourceware.org/cygwin-apps/setup.html


Please send bug reports, as usual, to the public mailing list cygwin AT 
cygwin DOT com.

Re: Cygwin/X with Win10 display scaling corrupting font display of typed characters - Issue identified

Thanks for reporting this.

Any guidance, pointers, suggestions of avenues for further research, 
or other information, will all be greatly appreciated.


After more research and experimentation, it appears to be related to 
one of xorg-server, xorg-server-common, or xorg-server-xorg.


Installing the older version 1.20.12-1 of these packages allows the 
windows to be moved between monitors without any issues. Upgrading to 
the current version 21.1.3-1 creates the problems. I'm able to 
replicate this behavior on two different laptops with two different 
external monitors.


It seems likely that this is an unintended effect of changes in 
xorg-server 21.1.0-1, trying to fix problems in this area (See [1])


Thanks for the references. I've read all the messages in the thread - I 
was particularly intrigued by this comment:


wrt the font scaling issue, looking at the source, it seems that we
don't re-consider the display dpi after a WM_DISPLAYCHANGE message, but
keep on using the value determined at startup.  This is probably a bug.

I'm curious enough to want to take a look at the code, but I've got no 
belief that I'm going to be able to find an answer. (I'm *not* a C++ 
programmer. I can read it and write a little of it, but that's about 
it.) I was going to start by comparing the last known-working version to 
the first known-non-working version, but given that it's a major release 
change, that's not likely going to be a useful approach. (I'm way out of 
my league here. It's probably going to take me a long time just to get 
to the point where I can even begin to explore this.)


The relevant change, which tries to fix the issue identified in that 
comment, and probably introduces this issue is:


https://gitlab.freedesktop.org/jturney/xserver/-/commit/b19b6266d33f2b911dc1826ad5c03da135a39957

[...]

If I change the scaling from 125% to 100% on the laptop's display,
the problem appears until I restart Cygwin/X. Restarting Cygwin/X
shows it displaying properly, until I change the scaling again.


I could only reproduce this problem with mis-rendering when changing 
the scaling on the secondary monitor.


Wow, I did a really poor job of writing that. I'm sorry.

For clarity, just in case you were unable to interpret what I meant by 
what I wrote -


At start: Laptop scaling set at 125%, second monitor at 100%.

Mis-rendering occurs at start, on the second monitor only.

If I change the scaling on the laptop, while the current instance of 
XWin is running - the same mis-rendering now occurs on the laptop.


Interestingly enough, if I change the laptop from 125% to 100%, the tops 
are clipped as previously reported. But if I change the scaling from 
125% to 150%, then the bottoms are clipped. (It kinda makes sense from 
what you've written.)


If I then stop and restart XWin after having reset the scaling such that 
both monitors have the same setting, then the problem doesn't appear.


Thanks for the clarification.

The laptop display is the primary monitor in all cases, correct?

Probably, this is not a new issue. But, it was hidden by:

Even with the following setting (by default),
(gdb) info signal SIGINT

inferior receives SIGINT when Ctrl-C is pressed.
Due to this behaviour, inferior cannot be continued
by 'cont' command after Ctrl-C. Is this the known issue?


Not known by me.

Are you saying this is a new issue in this gdb package?

This is an intersection of two tricky areas (Ctrl-C handling and signal 
handling), so misbehaviour is believable :).

It did, thank you.
