Re: selection to clipboard in xterm

[Sven Severus]

 Hallo Gery,

thanks for your reply.
Inside xterm the middle button works fine to paste,
but what I need is to paste in arbitrary windows
applications - just by using the windows clipboard.
And that does not work.

Sven

Re: Git version, XWin dies in cygwin but not in Windows

This is absolutely the right place :-)

I presume by 'git version' you mean the X.Org master tree.


and I am experiencing a
problem (May be it is also a problem on the official Xwin).
Sometime ( I can not make a reproducible test case) when the server
stops, the Xwin process disappears from Cygwin (as expected) but the
Windows process XWin.exe still be alive.


There are currently quite a few patches applied on top of the X.Org releases 
to make the cygwin released version (cygwin releases are tagged in [1]), at 
least one of which is related to stability during shutdown [5].


If you want a tree with those patches forward ported to xserver 1.9, take a 
look at [2]


Sorry that the contributors guide documentation is somewhat out of date and 
doesn't contain this information.



After some investigations (I'm not a good Windows hacker) it seems
that the process hangs  on the call to PostQuitMessage (0); of the
function ddxGiveUp of the file InitOutput.c

I can't tell why (Like I said, I'm not a good Windows hacker) but my
tests seems to show that delete this call  fixes the bug (may be there
is no link ).

Is it possible that this problem lies to the fact that the main window
is destroyed before the call to PostQuitMessage  (So the WM_QUIT
message can't be treated isn't it ?)


That shouldn't be the case, PostMessage() [3] functions are supposed to by 
asynchronous (unlike SendMessage() [4] which is synchronous, waiting for the 
message to be processed before returning)

Have you tried SHIFT+INSERT to paste text into those windows?

Re: XWin crash after the launch of startkde on a remote Red Hat 5 machine

Hi Jon,


Firstly, thanks very much for looking at this.


You will find attached to this Email a patch (for the git version)
which implements for the clipboard thread :
  - Auto cleanup function
  - Auto restart function for unexpected exit of the clipboard or
Xerror detection
  - Deletion of XQuery wrapper  (not needed anymore)
  - Deletion of all the xdmcp related tricks  (not needed anymore)


For purposes of review it would be easier to split this patch into two 
separate patches, (i) the clipboard thread changes and (ii) removing the 
unneeded xdmcp tricks.



One thing, this patch deletes the call to EmptyClipboard () in the
winProcSetSelectionOwner function of the winclipboardwrappers.c file
when an "owned to not owned transition" has been detected. I don't
know why but it was freezing the server for 1 or 2 seconds during
clipboard's restart in xdmcp connection.


Hmmm... I wonder if that's something to do with how we process the 
WM_DESTROYCLIPBOARD message?  In any case, this should not be happening.



It would be fine if you could tell me, when you think this patch and
the previous one ( which makes the reset of the server working
correctly with clipboard) will be included to the official X server?


We don't have a regular release cycle for the cygwin X server, so I can't 
answer that question accurately.


I shall put your previous patch into the next release and assuming it works 
well, be pushing it upstream sometime before xserver 1.10


I think this patch needs a little more work.

I'm still a little concerned that there is no rate-limiting on the clipboard 
restart mechanism, so in a pathological case (e.g. where some unanticipated 
error causes the clipboard to constantly get disconnected), this will spin 
using all available CPU.


Some detailed comments below.

This comment doesn't appear to be correct.  winInitClipboard() starts the

It looks like this could fight with the ProcEstablishConnection wrapper, which

Hi Jon,

Can I assume that when you announce a patched version of XWin.exe for
testing, that the test version includes all of the prior patches, up
to and including the one being tested?

Thanks - Jim

Commercial Use

[Donald Fagan]

Hi,

I can't seem to find on your site if cygwin-x can be used
commercially. If it can is there any cost for a licence.
I intend to used it as a possible replacement for reflection x to
access an old HP-UX server.

Thanks,

Donald

Have a look at .  Basically, any kind of use
is OK, it's further distribution that requires attention to licensing.

Re: selection to clipboard in xterm

[Sven Severus]

Thanks to your Reply, Jim.
Yes, I tried SHIFT+INSERT (which I know from 
XEmacs) to paste, but I never get pasted into 
a windows application what I highlighted in my 
xterm earlier on. Nevertheless, from one xterm 
to another xterm this works fine...

One additional remark: When I highlight a piece 
of text in my xterm, the content of the windows 
clipboard does not remain unaffected: it is 
cleared (reset to the empty string).
Even harder for me to understand ;-> ...

Greetings, Sven
