Brian gave you a very polite and helpful reply. But you didn't do your part
by asking a reasonable question. You didn't even tell us what you were
trying to compile, or bother to write a useful subject to your email! With
a question like that, don't expect a useful answer. You got one anyway.

[ANNOUNCEMENT] stunnel 5.56-1

[Andrew Schulman via cygwin]

stunnel 5.56-1 is now available in Cygwin. This release includes minor bug
fixes and documentation improvements. Please see the upstream changelog[1]
for the full list.

stunnel is a program that allows you to encrypt arbitrary TCP connections
inside TLS (Transport Layer Security, the successor to Secure Sockets Layer
(SSL)).  stunnel can allow you to secure non-TLS-aware daemons and
protocols (like POP, IMAP, LDAP, etc) by having stunnel provide the
encryption, requiring no changes to the daemon's code.

[ANNOUNCEMENT] multitail 6.5.0-1

[Andrew Schulman via cygwin]

multitail 6.5.0-1 is now available in Cygwin. This is a new upstream
release. The author of multitail doesn't provide an up-to-date changelog,
but there's a little bit of explanation on the project home page[1], and an
older changelog[2].

MultiTail lets you view one or multiple files like the original tail
program. The difference is that it creates multiple windows on your console
(with ncurses). It can also:

* Monitor wildcards: if another file matching the wildcard has a more
recent modification date, it will automatically switch to that file. That
way you can, for example, monitor a complete directory of files. 
* Merge 2 or more logfiles.
* Use colors while displaying the logfiles (through regular expressions),
for faster recognition of what is important and what not. 
* Filter lines (again with regular expressions) and has interactive menus
for editing given regular expressions and deleting and adding windows. 
* Have windows with the output of shell scripts and other software. When
viewing the output of external software, MultiTail can mimic the
functionality of tools like 'watch' and such.

Re: stow package missing dependency

Hi. Hm, sorry about that. Yes, stow does depend on perl-Stow, which is just
a Perl package split out of the build from the same source. But I see that
cygport didn't find it as a dependency, so it didn't make it into the
dependency list.

Yaakov, any thoughts on why cygport didn't spot perl-Stow as a dependency
of stow? I just rebuilt stow and found the same thing:

>>> stow requires: perl-Scalar-List-Utils perl_base
>>> perl-Stow requires: perl_base

Anyway, I'll upload a new version with the dependency included. Thanks for
reporting that.

Different problem, when stow had to be rebuilt for a new Perl version.

[ANNOUNCEMENT] stow 2.3.1-2

[Andrew Schulman via cygwin]

stow 2.3.1-2 is now available in Cygwin. 

This release is identical to the previous release, 2.3.1-1, except that it
includes the dependency on the perl-Stow package, which was missing in just
the previous release I believe. So if you installed stow for the first time
in the last release, it might not have worked for you. That's fixed now.

Stow manages the installation of local software packages by creating sets
of symlinks from the installed location (e.g. /usr/local) to a stow
directory (e.g. /usr/local/stow/emacs) where the real files live. This
allows you to keep packages separate, while making them appear to be
installed in the same place.

[ANNOUNCEMENT] lftp 4.9.0-1

[Andrew Schulman via cygwin]

lftp 4.9.0-1 is now available in Cygwin. This release has lots of small new
features and bug fixes. Please see the upstream changelog at
http://lftp.tech/news.html.

lftp is a sophisticated file transfer program and ftp/http/bittorrent
client. It supports multiple network protocols.  It offers tab completion,
command history, job control, and bookmarks. It can mirror sites and
transfer multiple files in parallel. It keeps trying interrupted operations
until it can complete them.

[ANNOUNCEMENT] lftp 4.9.0-2

[Andrew Schulman via cygwin]

lftp 4.9.0-2 is now available in Cygwin. This is a Cygwin-only update that
tries to fix a segmentation fault some users are seeing in the previous
release, 4.9.0-1[1].

The bug appears to happen only on hosts that aren't IPv6-enabled. The fix
was helpfully contributed by Henry S. Thompson[2]. Thank you, Henry.

I haven't been able to test the patch, since the problem doesn't occur on
any of my hosts. Since version 4.9.0-1 seems to be partly or completely
broken for many users, rather than wait I decided to go ahead and release
this new, patched version to see if it fixes the problem.

Please test this new release, and report on the Cygwin list if the problem
is fixed for you.

[ANNOUNCEMENT] screen 4.8.0-1

[Andrew Schulman via cygwin]

screen 4.8.0-1 is now available in Cygwin. This release includes several
bug fixes, including a fix for a memory overwrite that could be a security
vulnerability. Everyone is urged to upgrade to this release.

See the release announcement[1] and upstream changelog[2] for more details.

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells. Each virtual
terminal provides the functions of the DEC VT100 terminal and, in addition,
several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022
standards (e.g., insert/delete line and support for multiple character
sets). There is a scrollback history buffer for each virtual terminal and a
copy-and-paste mechanism that allows the user to move text regions between
windows. When screen is called, it creates a single window with a shell in
it (or the specified command) and then gets out of your way so that you can
use the program as you normally would. Then, at any time, you can create
new (full-screen) windows with other programs in them (including more
shells), kill the current window, view a list of the active windows, turn
output logging on and off, copy text between windows, view the scrollback
history, switch between windows, etc. All windows run their programs
completely independent of each other. Programs continue to run when their
window is currently not visible and even when the whole screen session is
detached from the user's terminal.

Yes, I could do that. I was hoping to avoid it, but it may be the only realistic
solution. 

It may be mainly Unison 2.48 that's affected, and maybe also 2.51 and the
forthcoming 2.52. I guess that very few people are still using the older
versions, and if they are they don't want any changes now.

Thanks, that's helpful to know. Your situation might not be unusual, I don't
know. For all I know, you and I are the only Cygwin Unison users.

So was unison2.48-2.48.4-1 built with OCaml 4.04.1? I don't remember, and I'm
not sure how to tell.

[ANNOUNCEMENT] stow 2.3.0-1

[Andrew Schulman via cygwin]

stow 2.3.0-1 is now available in Cygwin. This release has many new
features, bug fixes, and documentation improvements since the previous
release, 2.2.2-2. See the upstream changelog at
https://git.savannah.gnu.org/cgit/stow.git/tree/NEWS.

Stow manages the installation of local software packages by creating sets
of symlinks from the installed location (e.g. /usr/local) to a stow
directory (e.g. /usr/local/stow/emacs) where the real files live. This
allows you to keep packages separate, while making them appear to be
installed in the same place.

[ANNOUNCEMENT] stow 2.3.1-1

[Andrew Schulman via cygwin]

stow 2.3.1-1 is now available in Cygwin. This release has a few bug fixes,
mainly removal of a run-time dependency on the Perl Hash::Merge and
Clone::Choose libraries. See the upstream changelog at

[ANNOUNCEMENT] screen-4.7.0-1

[Andrew Schulman via cygwin]

screen-4.7.0-1 is now available in Cygwin. This release includes lots of
small fixes and documentation improvements. See the upstream changelog[1]
for details.

This release also includes a small change to the default /etc/screenrc,
reported to fix a screen corruption problem for some users, that was
included in the test release 4.6.2-3[2].

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells. Each virtual
terminal provides the functions of the DEC VT100 terminal and, in addition,
several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022
standards (e.g., insert/delete line and support for multiple character
sets). There is a scrollback history buffer for each virtual terminal and a
copy-and-paste mechanism that allows the user to move text regions between
windows. When screen is called, it creates a single window with a shell in
it (or the specified command) and then gets out of your way so that you can
use the program as you normally would. Then, at any time, you can create
new (full-screen) windows with other programs in them (including more
shells), kill the current window, view a list of the active windows, turn
output logging on and off, copy text between windows, view the scrollback
history, switch between windows, etc. All windows run their programs
completely independent of each other. Programs continue to run when their
window is currently not visible and even when the whole screen session is
detached from the user's terminal.

Hi Christian. Thanks for reporting this, and sorry for my slow reply. I was
suprprised by this, because I thought setup would set up rational permissions
for us. I've just come to expect that permissions on my Cygwin files get set to
screwy values, and I thought that setup was fixing them up for us.

Anyway I fixed the permissions in version 3.5.1-2, which I just uploaded. Once
you update to that version, please let me know if everything looks okay again.

dig and host don't work in IPv6

[Andrew Schulman via Cygwin]

Our agency has started using IPv6. My PC has IPv4 and IPv6 addresses. DNS
servers are all IPv6 addresses.

All of this works great, except that now the host and dig commands no longer
work, even with -6:

$ dig -6 cygwin.com

; <<>> DiG 9.11.9 <<>> -6 cygwin.com
;; global options: +cmd
;; connection timed out; no servers could be reached


It does work if I specify the DNS server in the command:

$  dig @2620:117:5010:1a1::f005 cygwin.com

; <<>> DiG 9.11.9 <<>> @2620:117:5010:1a1::f005 cygwin.com
; (1 server found)

It also works if I manually add a 'nameserver' line to /etc/resolv.conf. That's
not a sustainable solution though, since the nameservers change and I drop into
and out of the IPv6 VPN.

Should I be doing something differently? Or is it a bug?

Thanks,
Andrew

Thanks. Unfortunately neither of those options fixes the problem.

And yes, other Cygwin network clients work normally, for example curl and ssh.

No help unfortunately.

$ host -d6 cygwin.com
Trying "cygwin.com"
;; connection timed out; no servers could be reached

> (strace can help as well, I think.)

Posted at https://pastebin.com/XWwxJ41b. I'm not able to make much sense of it,
except that on line 1339, I waited almost 5 seconds for sendmsg:

4964291 6958349 [isc-worker] host 20999 cygwin_sendmsg: 28 = sendmsg(20,
0x7FFDFC830, 0x0)

Thanks for taking a look. I'm looking at other options in resolv.conf, but
haven't found anything useful.

I can't find any documention of the osquery option. This answer[1] says
"res_init() uses the Windows resolver if either /etc/resolv.conf does not exist,
or /etc/resolv.conf contains options osquery." Doesn't help in this case though.

Yes. Put the following in either /etc/fstab (system-wide) or /etc/fstab.d/myuser
(user-specific):

H:/  /home/myuser  nfs  binary,user  0 0

Then run mount -a, or exit and restart your shell. To learn more see the Cygwin

Marco, thanks. But I thought the request was fine.

Ouch! Sorry everybody! And thank you Xavier, for reporting that.

Yes, I'll add a dependency on procps-ng to future releases. cygport finds so
many dependencies automatically, I guess I thought it would find that one too.

And now I see that the cygport documentation[1] says that we still have to add
dependencies to REQUIRES if they're used in scripts, as in this case.

Hi. I'm the stunnel maintainer for Cygwin. I don't know why stunnel would hang
as you describe, but I'll try to help.

I agree that your configuration of ssh over TLS is common - I used it myself for
years. However as matthew patton suggests, there are other ways to get the same
goal, that may let you work around this problem.

One possibility that matthew didn't mention, is to run your ssh server on port
443, and connect directly to it with ssh - no TLS wrapper. Yes, that's
non-standard, but if you can live with that, it might work fine for you and be
simpler. My best understanding is that ssh and TLS are indistinguishable to an
application firewall.

But supposing you keep your current configuration. Can you please clarify how
you're invoking stunnel? Do you have a ProxyCommand directive in your
.ssh/config, like:

ProxyCommand /usr/bin/stunnel stunnel.conf

or is it some other way? I ask this because with ProxyCommand as above, you
should get a separate stunnel process for each new ssh connection, and I can't
think why they would interfere with each other.

Andrew

OK. So why that worked before and it doesn't work now, I don't know. But what
that sounds like to me is that you have only one stunnel process. When you
reproduce the problem, how many stunnel processes are running?

ps | grep stunnel

The advantage of using ProxyCommand in your ssh config is that it starts a
separate stunnel process for each connection, which should avoid this problem.

If you don't usually need stunnel, you can create one two ssh configurations
with different names, one with ProxyCommand and one without, and use whichever
one you need.

cause that fault in Cygwin. socat in Cygwin is compiled OOTB, with no
patches. Any debugging or patches would be welcome. Andrew

On the one hand, it's not much more work to build packages for x86.

On the other hand, 32-bit Cygwin will still be available - it just won't be
updated, unless package maintainers want to. It's been many years since
32-bit PCs were sold. I don't know how many 32-bit PCs are still in use and
running Cygwin, but it can't be very many.

Overall, I agree that it's time.

Yes, I recompiled my example after rebuilding and reinstalling libargp.  It

I haven't used cygport up in a long time - I use git push now, and let scallywag
build the packages - but this does seem like new wrong behavior. Surely he
shouldn't have to use keychain to get cygport to work? According to the docs, as
you cited, his method should work. Andrew

Yes!

Once you push your .cygport file up to the package's Cygwin git repo, the
package build service will try to build it:

Thanks for flagging this. I've always understood that setup (or cygport?) sets
suitable permissions on package files, but if that's not true, we maintainers

OK. I just verified that when I build a local package tarball with cygport all
of the files are world-readable. So I don't seem to be doing anything actively
wrong. I'll bump the version number and try scallywag again.

[ANNOUNCEMENT] unison2.48-2.48.4-2 (Warning: possible breakage)

[Andrew Schulman via Cygwin-announce]

The unison2.48 package has been updated in Cygwin. This new release,
version 2.48.4-2, has been rebuilt with OCaml 4.08.1, which makes it
compatible for syncing with Ubuntu Focal and the current Debian testing.

*Warning*: This update may be a breaking change, if you use unison2.48 to
synchronize with hosts that run other Linux distros. This is because two
Unison executables have to be built with the same version of OCaml in order
to be compatible. For discussion of this newly-discovered problem and how
we plan to deal with it in Cygwin, see OCaml Versions, below.

== Unison Versions in Cygwin

Unison is packaged for Cygwin as several independent packages, each
providing a version of Unison that is incompatible with the others. You
have to run compatible versions of Unison on the client and server, or
Unison will issue an error message and quit. Two versions of Unison are
compatible only if the first two numbers in their version strings are the
same. For example, all versions 2.48.* are compatible with each other, and
incompatible with versions 2.51.*. By installing one or more of the
packages listed above, you can run whichever version you need in order to
synchronize with your server.

The unison* packages install a convenience symlink from /usr/bin/unison to
one of the versioned unison executables, e.g. unison-2.48.exe.
alternatives(8) is used to manage the symlink. If the symlink is being
managed in "auto" mode, then it will automatically track the highest
numbered version of unison that you have installed. You can override this
by either changing the symlink manually with ln(1), or, preferably, by
using alternatives(8):

alternatives --display unison   shows you the installed versions of unison,
their priorities, which executable the symlink points to, and whether the
symlink is being managed in "auto" or "manual" mode.

alternatives --config unison   presents a menu from which you can choose
which version you want to use as the default.  This puts the symlink in
manual mode.

alternatives --auto unison   puts the symlink in automatic mode, where it
will always point to the highest numbered version of unison that's
installed on your host.

alternatives --set unison /usr/bin/unison-$V.exe   forces the symlink to
point to unison-$V.exe, and puts it in manual mode.

Please see alternatives(8) for more details.

== OCaml Versions

There is unfortunately another layer of incompatibility in Unison: Two
Unison executables are only compatible if they were built with the same
version of OCaml. If you use, say, Unison 2.48 on two different hosts, but
one was built with OCaml 4.08.1 and the other with OCaml 4.10.0, you'll get
the dreaded error message

  Fatal error: Fatal error during unmarshaling (input_value: ill-formed
  message), possibly because client and server have been compiled with 
  different versions of the OCaml compiler.

This is a bad feature, of OCaml apparently. It means that in order to be
sure of being able to sync with another host, we could potentially need a
separate Unison package for every combination of Unison and OCaml.

For now, Unison packages for Cygwin are being built with the OCaml version
that seems to make them most generally compatible with other Linux distros:

Package OCaml version  Compatibility
--  -  -
unison2.27  ?  ?
unison2.32  ?  ?
unison2.40  ?  ?
unison2.45  ?  ?
unison2.48  4.08.1 Debian bullseye (testing), Ubuntu Focal
unison2.49  ?  ?
unison2.51  ?  ?

Packages with "?" are older builds, where the OCaml version isn't currently
known.

If your distro uses a different combination of Unison and OCaml versions
that you need in order to sync, please let me know here. If it's widely
used, I might update one of the existing builds, or make a new Cygwin
package for it.

Future versions of Unison may get around the OCaml version incompatibility.
For more discussion of the problem, see
http://lists.seas.upenn.edu/pipermail/unison-hackers/2020-August/001972.html.

[ANNOUNCEMENT] New: unison2.48+4.04.2, unison2.48+4.08.1 [test]

[Andrew Schulman via Cygwin-announce]

Two new Unison packages are now available in test:

unison2.48+4.04.2
unison2.48+4.08.1

Both of these are Unison 2.48.4, but compiled with OCaml 4.04.2 and 4.08.1,
respectively. For the reasons explained below, we now need separate Unison
packages for compatible versions of both Unison and OCaml.

If you use Unison 2.48, please test these packages to see if one of them
works to synchronize with your server, and report the results here. If they
don't work for you, we can add other combinations. Once these packages move
to the current release, they'll obsolete the current unison2.48 package, so
please test them now.

Unison is a file synchronizer for Unix and Windows. It allows two replicas
of a collection of files and directories to be stored on different hosts
(or different disks on the same host), modified separately, and then
brought up to date by propagating the changes in each replica to the other.

== Unison versions and packages

Unison comes in several complementary packages for Cygwin:

   Unison   OCaml
Package name   version  version  Unison executable
   ---  ---  -
unison2.27 2.27.*   4.01.0   /usr/bin/unison-2.27
unison2.32 2.32.*   4.01.0   /usr/bin/unison-2.32
unison2.40 2.40.*   4.02.3   /usr/bin/unison-2.40
unison2.45 2.45.*   4.01.1   /usr/bin/unison-2.45
unison2.48+4.04.2  2.48.*   4.04.2   /usr/bin/unison-2.48+4.04.2
unison2.48+4.08.1  2.48.*   4.08.1   /usr/bin/unison-2.48+4.08.1
unison2.49 2.49.*   4.02.3   /usr/bin/unison-2.49
unison2.51 2.51.*   4.04.2   /usr/bin/unison-2.51

You can install any number of these packages side-by-side. Separate
packages are needed because in order to synchronize your files, you have to
run compatible versions of Unison on the client and server. Two Unison
executables are compatible if and only if:

(1) They have the same first two numbers of the Unison version. For
example, all Unison versions 2.48.* are compatible with each other. But if
you try to use version 2.51.x to sync with a server running version 2.48.y,
Unison will issue an error message about incompatible versions and quit.

AND

(2) They were built with compatible versions of the OCaml compiler. OCaml
has changed its format over time for "marshaling" or serializing data. If
you run Unison executables that were built with OCaml versions that use
different marshaling formats, even if the Unison versions are the same,
you'll get the dreaded error message

  Fatal error: Fatal error during unmarshaling (input_value: ill-formed
  message), possibly because client and server have been compiled with 
  different versions of the OCaml compiler.

Apparently OCaml introduced breaking changes to its marshaling format in
versions 4.08 and 4.11. So versions pre-4.08, between 4.08 and 4.11, or
post-4.11 should be mutually compatible. But this hasn't been tested much.
For discussion of OCaml version incompatibilities, see
https://lists.seas.upenn.edu/pipermail/unison-hackers/2020-August/001972.html
.

By installing one or more of the packages listed above, you can run
whichever version you need in order to synchronize with your server. If you
need a different combination of Unison and OCaml versions than is available
in the current packages, please send a report to cygwin@cygwin.com. It may
be possible to create a new package for it.

== Setting a default version

The package postinstallation scripts use alternatives(8) to install a
symlink /usr/bin/unison that points to one of the above-named executables.
By default this symlink will track the highest-numbered version of Unison
that you install on your system. You can change that using alternatives:

  alternatives --config unison

(recommended) or manually. See "man alternatives" for details.

If the server provides multiple versions of Unison, then you can invoke
Unison on the client with e.g. '-servercmd /usr/bin/unison-2.48' to run the
version you want on the server, or put 'servercmd /usr/bin/unison-2.48'
into the client's preference file.

== User interface

All of the Unison packages for Cygwin use the text UI. There is also a GTK2
UI for Unison, but I haven't been able to get it working yet under Cygwin.
At some time in the future I may make unison*+gtk2 packages available for
Cygwin.

client. It supports multiple network protocols.  It offers tab completion,
command history, job control, and bookmarks. It can mirror sites and
transfer multiple files in parallel. It keeps trying interrupted operations
until it can complete them.

[ANNOUNCEMENT] discus 0.4.0-1

[Andrew Schulman via Cygwin-announce]

discus 0.4.0-1 is now available in Cygwin. This release adds Python 3
compatibility, and minor improvements such as adapting its display to the
terminal width.

Discus aims to make df prettier, with features such as color, graphs, and
smart formatting of numbers (automatically choosing the most suitable size
from kilobytes, megabytes, gigabytes, or terabytes). If you don't want
Discus deciding the best sizes, you can also choose your own increments,
along with specifying the number of decimal places you'd like to see.

[ANNOUNCEMENT] fish-3.1.2-2

[Andrew Schulman via Cygwin-announce]

fish 3.1.2-2 is now available in Cygwin. This release updates the default
fish_prompt function to the version shipped in the upstream fish 3.1.2.

The new default prompt function has lots more stuff in it, like a colored
username, version control branch name, and numerical exit status code of
the previous command, if it ended in an error status. 

Personally, I find all of that to be too much information for a shell
prompt. But it's what the fish project ships now, so Cygwin is including
it. If you want to change/simplify the prompt, you can:

* Change fish's colors. For example, you can set the username color in the
prompt from bright green (!) back to normal by

  set -U fish_user_color normal

* Create your own fish_prompt function. You can start by copying it from
/usr/share/fish/vendor_functions.d/fish_prompt.fish into either of:

  /etc/fish/functions (for all users on the host)
  ~/.config/fish/functions (for just your account)

Then edit the function, for example to remove fish_vcs_prompt (which I find
also slows down the prompt) or prompt_status.

fish is the friendly interactive shell. It's a Unix shell that focuses on
interactive use, discoverability, and user friendliness. The design goal of
fish is to give the user a rich set of powerful features in a way that is
easy to discover, remember, and use.

[ANNOUNCEMENT] new: socat2 2.0.0-0.1.b9; updated: socat 1.7.3.4-2

[Andrew Schulman via Cygwin-announce]

The 1.x and 2.x versions of socat have now been separated into separate
packages for Cygwin.

socat 1.7.3.4-2 is now available. It's the same as the -1 package, but the
package hint now clarifies that it's the 1.x series.

socat2 2.0.0-0.1.b9 is now available. This is upstream version 2.0.0-b9.

socat is a relay for bidirectional data transfer between two independent
data channels. Each channel may be a file, pipe, device (serial line etc.
or a pseudo terminal), a socket (UNIX, IP4, IP6 - raw, UDP, TCP), an SSL
socket, proxy CONNECT connection, a file descriptor (stdin etc.), the GNU
line editor (readline), a program, or a combination of two of these. These
modes include generation of 'listening' sockets, named pipes, and pseudo
terminals.

[ANNOUNCEMENT] unison 2.53.0-1

[Andrew Schulman via Cygwin-announce]

 unison 2.53.0-1 is now available in Cygwin. This is a new upstream
release, with
new features and bug fixes. See the upstream release log[1] for details.

Unison is a file synchronizer for Unix and Windows. It allows two replicas
of
a collection of files and directories to be stored on different hosts (or
different disks on the same host), modified separately, and then brought up
to
date by propagating the changes in each replica to the other.

== Unison versions and packages

Unison versions 2.52 and later are provided in Cygwin by the unison
package. The
executable is /usr/bin/unison-latest. All versions 2.52 and later are
compatible
with each other, so they can sync with each other. They can also sync with
Unison versions 2.48-2.51, but apparently not with versions older than
that.
Test reports are welcome on the Cygwin list, cygwin@cygwin.com.

Prior to version 2.52, Unison came in multiple complementary packages for
Cygwin:

   Unison   OCaml
Package name   version  version  Unison executable
   ---  ---  -
unison2.27 2.27.*   4.01.0   /usr/bin/unison-2.27
unison2.32 2.32.*   4.01.0   /usr/bin/unison-2.32
unison2.40 2.40.*   4.02.3   /usr/bin/unison-2.40
unison2.45 2.45.*   4.01.1   /usr/bin/unison-2.45
unison2.48+4.04.2  2.48.*   4.04.2   /usr/bin/unison-2.48+4.04.2
unison2.48+4.08.1  2.48.*   4.08.1   /usr/bin/unison-2.48+4.08.1
unison2.49 2.49.*   4.02.3   /usr/bin/unison-2.49
unison2.51+4.04.2  2.51.*   4.04.2   /usr/bin/unison-2.51+4.04.2
unison2.51+4.10.0  2.51.*   4.10.0   /usr/bin/unison-2.51+4.10.0

Different packages were needed because Unison executables were only
compatible
if they had the same Unison version, and were compiled with compatible
versions
of OCaml. (It was kind of a nightmare.) So you had to have a version
installed
locally that matched the version you were synchronizing with.

== Migrating to version 2.52 or later

To upgrade Unison on your local host to version 2.52 or later:

* If the remote host is also running Unison 2.52 or later, you're all set.

* If the remote host is running Unison 2.48-2.51, you can sync with it. If
  you've previously synchronized files with that host, try syncing with it
again
  with your local version 2.52 or later. If the two Unisons were built with
  compatible versions of OCaml, then the newer Unison will upgrade the local
  Unison archive files to the newer format. After that you can sync using
any
  later version of Unison, regardless of the OCaml version. But if Unison
throws
  an error about bad archives or the like, then you'll have to either go
back to
  using the previous Unison version, or (recommended) remove the previous
  archive files (~/.unison/ar* and ~/.unison/fp*), and start over with a
fresh
  synchronization.

* If the remote host is running a version older than 2.48, you can't sync
to it
  with version 2.52 or later. You'll have to keep using one of the older
Unison
  packages listed above, that matches the Unison and OCaml versions of the
  remote host.

The Unison 2.52 Migration Guide[2] has more detailed information.

== Setting a default version

The package postinstallation scripts use alternatives(8) to install a
symlink
/usr/bin/unison that points to one of the above-named executables. By
default
this symlink will track the highest-numbered version of Unison that you
install
on your system. You can change that using alternatives:

  alternatives --config unison

(recommended) or manually. See "man alternatives" for details.

If the server provides multiple versions of Unison, then you can invoke
Unison
on the client with for example '-servercmd /usr/bin/unison-2.51' to run the
version you want on the server, or put 'servercmd /usr/bin/unison-2.51'
into the
client's preference file.

== User interface

All of the Unison packages for Cygwin use the text UI. There is also a GTK3
UI
for Unison, but I haven't tried to build it for Cygwin yet.

[ANNOUNCEMENT] New: unison2.51+4.04.2, unison2.51+4.10.0

[Andrew Schulman via Cygwin-announce]

*Two new Unison packages are now available in
Cygwin:unison2.51+4.04.2unison2.51+4.10.0Both of these are Unison 2.51.5,
but compiled with OCaml 4.04.2 and 4.10.0, respectively. For the reasons
explained below, we now need separate Unison packages for incompatible
versions of both Unison and OCaml.unison2.51+4.04.2 obsoletes the older
unison2.51 package, and is a newer Unison release (2.51.5 versus 2.51.2).
They're built with the same version of OCaml, so if you've been syncing
with unison2.51 before, you can use unison2.51+4.04.2 in place of it
now.Please test and report any problems here. If you need a different
combination of Unison and OCaml versions, please report that here and I'll
consider creating a new package for it.Unison is a file synchronizer for
Unix and Windows. It allows two replicas of a collection of files and
directories to be stored on different hosts (or different disks on the same
host), modified separately, and then brought up to date by propagating the

/usr/bin/unison-2.51+4.10.0You can install any number of these packages
side-by-side. Separate packages are needed because in order to synchronize
your files, you have to run compatible versions of Unison on the client and
server. Two Unison executables are compatible if and only if:(1) They have
the same first two numbers of the Unison version. For example, all Unison
versions 2.48.* are compatible with each other. But if you try to use
version 2.51.x to sync with a server running version 2.48.y, Unison will
issue an error message about incompatible versions and quit.AND(2) They
were built with compatible versions of the OCaml compiler. OCaml has
changed its format over time for "marshaling" or serializing data. If you
run Unison executables that were built with OCaml versions that use
different marshaling formats, even if the Unison versions are the same,
you'll get the dreaded error message  Fatal error: Fatal error during
unmarshaling (input_value: ill-formed  message), possibly because client
and server have been compiled with  different versions of the OCaml
compiler.Apparently OCaml introduced breaking changes to its marshaling
format in versions 4.08 and 4.11. So versions pre-4.08, 4.08 through 4.10,
or 4.11 and later should be mutually compatible. But this hasn't been
tested much. For discussion of OCaml version incompatibilities,
seehttps://lists.seas.upenn.edu/pipermail/unison-hackers/2020-August/001972.html

.By installing one or more of the packages listed above, you can run
whichever version you need in order to synchronize with your server. If you
need a different combination of Unison and OCaml versions than is available
in the current packages, please send a report to cygwin@cygwin.com
. It may be possible to create a new package for it.==
Setting a default versionThe package postinstallation scripts use
alternatives(8) to install a symlink /usr/bin/unison that points to one of
the above-named executables. By default this symlink will track the
highest-numbered version of Unison that you install on your system. You can
change that using alternatives:  alternatives --config unison(recommended)
or manually. See "man alternatives" for details.If the server provides
multiple versions of Unison, then you can invoke Unison on the client with
e.g. '-servercmd /usr/bin/unison-2.48' to run the version you want on the
server, or put 'servercmd /usr/bin/unison-2.48' into the client's
preference file.== User interfaceAll of the Unison packages for Cygwin use
the text UI. There is also a GTK2 UI for Unison, but I haven't been able to
get it working yet under Cygwin. At some time in the future I may make
unison*+gtk2 packages available for Cygwin.*

[ANNOUNCEMENT] screen-4.9.0-1

[Andrew Schulman via Cygwin-announce]

screen 4.9.0-1 is now available in Cygwin. This release includes several
bug fixes, including for a possible denial of service by a crafted UTF-8
character sequence. Everyone is urged to upgrade to this release.

See the release announcement[1] and upstream changelog[2] for more details.

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells. Each virtual
terminal provides the functions of the DEC VT100 terminal and, in addition,
several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022
standards (e.g., insert/delete line and support for multiple character
sets). There is a scrollback history buffer for each virtual terminal and a
copy-and-paste mechanism that allows the user to move text regions between
windows. When screen is called, it creates a single window with a shell in
it (or the specified command) and then gets out of your way so that you can
use the program as you normally would. Then, at any time, you can create
new (full-screen) windows with other programs in them (including more
shells), kill the current window, view a list of the active windows, turn
output logging on and off, copy text between windows, view the scrollback
history, switch between windows, etc. All windows run their programs
completely independent of each other. Programs continue to run when their
window is currently not visible and even when the whole screen session is
detached from the user's terminal.

[ANNOUNCEMENT] stunnel-5.62-1

[Andrew Schulman via Cygwin-announce]

stunnel 5.62-1 is now available in Cygwin. This release has bug fixes and
minor improvements. Please see the upstream changelog[1] for the full list.

stunnel is a program that allows you to encrypt arbitrary TCP connections
inside TLS (Transport Layer Security, the successor to Secure Sockets Layer
(SSL)). stunnel can allow you to secure non-TLS-aware daemons and
protocols (like POP, IMAP, LDAP, etc) by having stunnel provide the
encryption, requiring no changes to the daemon's code.

[ANNOUNCEMENT] New: unison 2.52.0-2

[Andrew Schulman via Cygwin-announce]

unison 2.52.0-2 is now available in Cygwin.

Unison is a file synchronizer for Unix and Windows. It allows two replicas
of
a collection of files and directories to be stored on different hosts (or
different disks on the same host), modified separately, and then brought up
to
date by propagating the changes in each replica to the other.

== Unison versions and packages

Unison versions 2.52 and later are provided in Cygwin by the unison
package. The
executable is /usr/bin/unison-latest. All versions 2.52 and later are
compatible
with each other, so they can sync with each other. They can also sync with
Unison versions 2.48-2.51, but apparently not with versions older than
that. (Test reports are appreciated on the Cygwin list, cygwin@cygwin.com.)

Prior to version 2.52, Unison came in multiple complementary packages for
Cygwin:

Package name   Unison version  OCaml version  Unison executable
   --  -  -
unison2.27 2.27.*  4.01.0 /usr/bin/unison-2.27
unison2.32 2.32.*  4.01.0 /usr/bin/unison-2.32
unison2.40 2.40.*  4.02.3 /usr/bin/unison-2.40
unison2.45 2.45.*  4.01.1 /usr/bin/unison-2.45
unison2.48+4.04.2  2.48.*  4.04.2
/usr/bin/unison-2.48+4.04.2
unison2.48+4.08.1  2.48.*  4.08.1
/usr/bin/unison-2.48+4.08.1
unison2.49 2.49.*  4.02.3 /usr/bin/unison-2.49
unison2.51+4.04.2  2.51.*  4.04.2
/usr/bin/unison-2.51+4.04.2
unison2.51+4.10.0  2.51.*  4.10.0
/usr/bin/unison-2.51+4.10.0

Different packages were needed because Unison executables were only
compatible
if they had the same Unison version, and were compiled with compatible
versions
of OCaml. (It was kind of a nightmare.) So you had to have a version
installed
locally that matched the version you were synchronizing with.

== Migrating to version 2.52 or later

To upgrade Unison on your local host to version 2.52 or later:

* If the remote host is also running Unison 2.52 or later, you're all set.

* If the remote host is running Unison 2.48-2.51, you can sync with it. If
  you've previously synchronized files with that host, try syncing with it
again
  with your local version 2.52 or later. If the two Unisons were built with
  compatible versions of OCaml, then the newer Unison will upgrade the local
  Unison archive files to the newer format. After that you can sync using
any
  later version of Unison, regardless of the OCaml version. But if Unison
throws
  an error about bad archives or the like, then you'll have to either go
back to
  using the previous Unison version, or (recommended) remove the previous
  archive files (~/.unison/ar* and ~/.unison/fp*), and start over with a
fresh
  synchronization.

* If the remote host is running a version older than 2.48, you can't sync
to it
  with version 2.52 or later. You'll have to keep using one of the older
Unison
  packages listed above, that matches the Unison and OCaml versions of the
  remote host.


The Unison 2.52 Migration Guide[1] has more detailed information.

== Setting a default version

The package postinstallation scripts use alternatives(8) to install a
symlink
/usr/bin/unison that points to one of the above-named executables. By
default
this symlink will track the highest-numbered version of Unison that you
install
on your system. You can change that using alternatives:

  alternatives --config unison

(recommended) or manually. See "man alternatives" for details.

If the server provides multiple versions of Unison, then you can invoke
Unison
on the client with for example '-servercmd /usr/bin/unison-2.51' to run the
version you want on the server, or put 'servercmd /usr/bin/unison-2.51'
into the
client's preference file.

== User interface

All of the Unison packages for Cygwin use the text UI. There is also a GTK2
UI
for Unison, but I haven't been able to get it working yet under Cygwin. At
some
time in the future I may make unison*+gtk2 packages available for Cygwin.

[ANNOUNCEMENT] multitail 6.5.2-1

[Andrew Schulman via Cygwin-announce]

multitail 6.5.2-1 is now available in Cygwin. This is a new upstream
release. See the upstream changelog[1] for details.

MultiTail lets you view one or multiple files like the original tail
program. The difference is that it creates multiple windows on your console
(with ncurses). It can also:

* Monitor wildcards: if another file matching the wildcard has a more
recent modification date, it will automatically switch to that file. That
way you can, for example, monitor a complete directory of files.
* Merge 2 or more logfiles.
* Use colors while displaying the logfiles (through regular expressions),
for faster recognition of what is important and what not.
* Filter lines (again with regular expressions) and has interactive menus
for editing given regular expressions and deleting and adding windows.
* Have windows with the output of shell scripts and other software. When
viewing the output of external software, MultiTail can mimic the
functionality of tools like 'watch' and such.

the client with for example '-servercmd /usr/bin/unison-2.51' to run the
version you want on the server, or put 'servercmd /usr/bin/unison-2.51' into
the client's preference file.

== User interface

All of the Unison packages for Cygwin use the text UI. There is also a GTK3
UI for Unison, but I haven't tried to build it for Cygwin yet.

[ANNOUNCEMENT] socat 1.7.4.4-1

[Andrew Schulman via Cygwin-announce via Cygwin]

socat 1.7.4.4-1 is now available in Cygwin. This release has many small bug
fixes since the last Cygwin release, 1.7.4.3-1. See the upstream commit
log[1] for details.

socat is a relay for bidirectional data transfer between two independent
data channels. Each channel may be a file, pipe, device (serial line etc.
or a pseudo terminal), a socket (UNIX, IP4, IP6 - raw, UDP, TCP), an SSL
socket, proxy CONNECT connection, a file descriptor (stdin etc.), the GNU
line editor (readline), a program, or a combination of two of these. These
modes include generation of 'listening' sockets, named pipes, and pseudo
terminals.

[ANNOUNCEMENT] [test] fish 3.6.1-2

[Andrew Schulman via Cygwin-announce via Cygwin]

fish 3.6.1-2 is now available in Cygwin as a TEST release.

This release moves fish's universal variable files from its previous,
Cygwin-specific location (~/.config/fish/fish_variables.x86_64) to fish'
standard location (~/.config/fish/fish_variables). I've tested the migration
on my hosts, and it works for me, but I'd like to hear from other users
whether it works for them too, before I make the feature generally
available.

# Testing

Please test this release! It's pretty easy:

1. Back up your universal variables file
(~/.config/fish/fish_variables.x86_64) if you want to be sure, just in case
it should be lost.

2. Before you update, start fish and set a universal variable that you can
test after the migration, for example

set -U migrated

3. Install the test release of fish.

4. Start fish.

If the migration was successful:

* You should see a migration message like this from fish, just one time:

Migrated /home/andrew/.config/fish/fish_variables.x86_64 ->
/home/andrew/.config/fish/fish_variables

* The variable you set above should still be set. So for example

set -q migrated; and echo success; or echo failed

  should echo "success".

* Output of `ls ~/.config/fish` should include fish_variables, and not
  fish_variables.x86_64.

Please report here whether the above worked for you, and any error messages
you might see.

# Why we're doing this

In the past when Cygwin supported two architectures (i686 and x86_64), fish
kept separate universal variables files for the two architectures. Now that
only one architecture is supported, there's no need to do that anymore, and
there's some advantage to moving the file back to where vanilla fish expects
to find it.

# About fish

fish is the friendly interactive shell. It's a Unix shell that focuses on
interactive use, discoverability, and user friendliness. The design goal of
fish is to give the user a rich set of powerful features in a way that is
easy to discover, remember, and use.

[ANNOUNCEMENT] unison 2.53.3-1

[Andrew Schulman via Cygwin-announce via Cygwin]

unison 2.53.3-1 is now available in Cygwin. This is a new upstream release,
with new features and bug fixes. See the upstream release log[1] for
details.

Unison is a file synchronizer for Unix and Windows. It allows two replicas
of a collection of files and directories to be stored on different hosts (or
different disks on the same host), modified separately, and then brought up
to date by propagating the changes in each replica to the other.

== Unison versions and packages

Unison versions 2.52 and later are provided in Cygwin by the unison package.
The executable is /usr/bin/unison-latest. All versions 2.52 and later are
compatible with each other, so they can sync with each other. They can also
sync with Unison versions 2.48-2.51, but apparently not with versions older
than that. Test reports are welcome on the Cygwin list, cygwin@cygwin.com.

Prior to version 2.52, Unison came in multiple complementary packages for
Cygwin:

   Unison   OCaml
Package name   version  version  Unison executable
   ---  ---  -
unison2.27 2.27.*   4.01.0   /usr/bin/unison-2.27
unison2.32 2.32.*   4.01.0   /usr/bin/unison-2.32
unison2.40 2.40.*   4.02.3   /usr/bin/unison-2.40
unison2.45 2.45.*   4.01.1   /usr/bin/unison-2.45
unison2.48+4.04.2  2.48.*   4.04.2   /usr/bin/unison-2.48+4.04.2
unison2.48+4.08.1  2.48.*   4.08.1   /usr/bin/unison-2.48+4.08.1
unison2.49 2.49.*   4.02.3   /usr/bin/unison-2.49
unison2.51+4.04.2  2.51.*   4.04.2   /usr/bin/unison-2.51+4.04.2
unison2.51+4.10.0  2.51.*   4.10.0   /usr/bin/unison-2.51+4.10.0

Different packages were needed because Unison executables were only
compatible if they had the same Unison version, and were compiled with
compatible versions of OCaml. (It was kind of a nightmare.) So you had to
have a version installed locally that matched the version you were
synchronizing with.

== Migrating to version 2.52 or later

To upgrade Unison on your local host to version 2.52 or later:

* If the remote host is also running Unison 2.52 or later, you're all set.

* If the remote host is running Unison 2.48-2.51, you can sync with it. If
  you've previously synchronized files with that host, try syncing with it
  again with your local version 2.52 or later. If the two Unisons were built
  with compatible versions of OCaml, then the newer Unison will upgrade the
  local Unison archive files to the newer format. After that you can sync
  using any later version of Unison, regardless of the OCaml version. But if
  Unison throws an error about bad archives or the like, then you'll have to
  either go back to using the previous Unison version, or (recommended)
  remove the previous archive files (~/.unison/ar* and ~/.unison/fp*), and
  start over with a fresh synchronization.

* If the remote host is running a version older than 2.48, you can't sync to
  it with version 2.52 or later. You'll have to keep using one of the older
  Unison packages listed above, that matches the Unison and OCaml versions
  of the remote host.

The Unison 2.52 Migration Guide[2] has more information.

== Setting a default version

The package postinstallation script uses alternatives(8) to install a
symlink
/usr/bin/unison that points to one of the above-named executables. By
default
this symlink will track the highest-numbered version of Unison that you
install on your system. You can change that using alternatives:

  alternatives --config unison

(recommended) or manually. See "man alternatives" for details.

If the server provides multiple versions of Unison, you can invoke Unison on
the client with for example '-servercmd /usr/bin/unison-2.51' to run the
version you want on the server, or put 'servercmd /usr/bin/unison-2.51' into
the client's preference file.

== User interface

All of the Unison packages for Cygwin use the text UI. There is also a GTK3
UI for Unison, but I haven't tried to build it for Cygwin yet.

[ANNOUNCEMENT] stow 2.3.1+5.36-1

[Andrew Schulman via Cygwin-announce via Cygwin]

stow 2.3.1+5.36-1 is now available in Cygwin. This update makes stow work
with
Perl 5.36.

stow manages the installation of local software packages by creating sets of
symlinks from the installed location (e.g. /usr/local) to a stow directory
(e.g. /usr/local/stow/emacs) where the real files live.  This allows you to
keep packages separate, while making them appear to be installed in the same
place.

[ANNOUNCEMENT] libargp-20230708-1

[Andrew Schulman via Cygwin-announce via Cygwin]

A new release of libargp, version 20230708-1, is available in Cygwin. This
release contains many small improvements and bug fixes since the last release,
20110921-3 - yes, 12 years ago. For a list of the changes, see the upstream
commit log[1].

Argp is an interface for parsing unix-style argument vectors. Argp provides
features unavailable in the more commonly used getopt interface. These
features include automatically producing output in response to the ‘--help’
and ‘--version’ options, as described in the GNU coding standards. Using argp
makes it less likely that programmers will neglect to implement these
additional options or keep them up to date.

Argp also provides the ability to merge several independently defined option
parsers into one, mediating conflicts between them and making the result
appear seamless. A library can export an argp option parser that user programs
might employ in conjunction with their own option parsers, resulting in less
work for the user programs. Some programs may use only argument parsers
exported by libraries, thereby achieving consistent and efficient
option-parsing for abstractions implemented by the libraries.

The header file  should be included to use argp.

[ANNOUNCEMENT] screen 4.9.1-1

[Andrew Schulman via Cygwin-announce via Cygwin]

screen 4.9.1-1 is now available in Cygwin. This release includes bug fixes
and documentation updates. See the release announcement[1] and upstream
changelog[2] for more details.

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells. Each virtual
terminal provides the functions of the DEC VT100 terminal and, in addition,
several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022
standards (e.g., insert/delete line and support for multiple character
sets). There is a scrollback history buffer for each virtual terminal and a
copy-and-paste mechanism that allows the user to move text regions between
windows. When screen is called, it creates a single window with a shell in
it (or the specified command) and then gets out of your way so that you can
use the program as you normally would. Then, at any time, you can create
new (full-screen) windows with other programs in them (including more
shells), kill the current window, view a list of the active windows, turn
output logging on and off, copy text between windows, view the scrollback
history, switch between windows, etc. All windows run their programs
completely independent of each other. Programs continue to run when their
window is currently not visible and even when the whole screen session is
detached from the user's terminal.
