Re: Vista, new install, x server does not start, startxwin.bat missing
I think something else might be going on. Note the following line from the log file XWin was started with the following command line: /usr/bin/X :0 -auth /home/Tattie/.serverauth.2764 The start command is being run from a user Dvorah, but the start is trying to access a file under the user Tattie.

Let me start with this intro: 2.22.4-1 included a fix for GIO plugin loading on Win32[1], but once again they lumped Cygwin together with MinGW. Of course, not only did this not need to be "fixed" on Cygwin but they outright broke GIO and everything that depends on it, and I got to pick up the pieces. Hence the need for 2.22.4-2, which behaves as it should. So you might as well forget about 2.22.4-1, and focus on whatever issues you appear to be having with GIO. [1] http://git.gnome.org/browse/glib/commit/?h=glib-2-22&id=ae0a220b With 2.22.4-2, when I open a dialog box (for example clicking on the tool bar icon "Reading an existing file into an Emacs buffer"), in /tmp is created the directory 'fam-angelo' and 'ps' shows a 'gamin-server' running. This is the expected behaviour. GtkFileChooser uses GFileMonitor (whose backend uses FAM/Gamin) so that changes to the directory being browsed are displayed. When I quit from Emacs (C-x C-c), the Emacs window stays on the desktop until 'gamin-server' is removed, i.e. for at least 20-30 seconds, looking as if Emacs were hanging. I haven't seen this behaviour with other GTK+ apps, so I suspect it may be (YA) emacs/gtk+ bug. (Googling shows that this seems to happen a lot.)

[repro snipped] Mark, Thanks for the detailed bug report and clear reproduction steps. On 23/01/2010 22:02, Mark Lillibridge wrote: I am not a Windows programmer. Can someone tell me if it's okay for winWindowProc to block? In particular, could we make it block until the mieq queue is not full? I think blocking would just result in a deadlock, as the X server is only single-threaded. The windows message pump is called when the server has no other work to do. This should be documented in [1], although perhaps that is lacking in detail. I notice that winWakeHandler()/winBlockHandler() try to completely empty the windows message queue, which leads to this problem as the server won't get a chance to process anything (draining the mieq queue) until they return. It might be enough to resolve this problem to allow those functions to complete after processing a limited number of events (chosen so as to not overflow the mieq queue), or if they notice that the event queue has crossed some high-water mark threshold.

Re: new cygwin/x11 and backingstore
On 04/02/2010 15:25, anne crespy wrote: Hi, Before updating Cygwin/X with the new version (X11R7) I launched Xwin with this command : XWin -multiwindow -clipboard -silent-dup-error +bs& and the backingStore option worked correctly in a graphic window (built with tcl/tk8.4 and Xlib). You were just lucky :-) The backing store attribute is a hint; the server doesn't have to honour a request to use backing store. Note that even if you have an X server which does provide backingstore, the server doesn't have to provide an unlimited amount of memory for it, so it may discard backingstore at any time. Any X client which *requires* backingstore to work is broken, not correctly redrawing windows when they are exposed. See [1] Now, it doesn't work. When the graphic window is overlapped its contents is corrupted by the top window. I didn't have this problem with the beta-version in november 2009. What have changed since? backingstore is implemented in terms of Composite in the X.Org server since X server 1.5.0 Unfortunately, we have had to disable Composite in the current X server due to crashes. If/when these problems with Composite are fixed, things may work a little better...

libglib2, Emacs and GTK applications
Just for completeness, I want to flag some strange things that I see
between a GTK build of Emacs and libglib2.0_0-2.22.4-2 BUT NOT with
libglib2.0_0-2.22.4-1!
With 2.22.4-2, when I open a dialog box (for example clicking on the
tool bar icon "Reading an existing file into an Emacs buffer"), in /tmp
is created the directory 'fam-angelo' and 'ps' shows a 'gamin-server'
running. When I quit from Emacs (C-x C-c), the Emacs window stays on the
desktop until 'gamin-server' is removed, i.e. for at least 20-30
seconds, looking as if Emacs were hanging.
This behavior does not happens with version 2.22.4-1. The
'/tmp/fam-angelo' directory is not created and 'gamin-server' or is not
started or it is removed immediately when it does not need any more.
Also the 'apparent' hanging disappears.
The above facts should be verified also with the following test case of
GTK application I found in this list. It should be build with:
gcc -DTRY1 -Wall -o test-dialog3-try1-01 test-dialog3.c `pkg-config
--cflags --libs gtk+-2.0
Then
$ ./test-dialog3-try1-01.exe
under libglib2-2.22.4-2 creates /tmp/fam-angelo and starts
'gamin-server' which is removed only after 20-30 seconds. With 2.22.4-1,
it is removed imediately (or does not start at all!).
Ciao,
Angelo.

Re: startxwin.exe and ssh-agent

In the 1.5 world, I modified startxwin.bat to prefix the XWin.exe line with ssh-agent, and this worked a treat. How should I do this now? I basically want my whole Xserver to run as a child of my ssh-agent so all xterms and other processes will collect the credentials. Creating a shortcut which starts the X server with: 'C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c "ssh-agent startxwin"' should probably do what you want. Note that (as before), processes you start other than via the X traymenu (for example, from a start menu item) aren't children of ssh-agent, so won't inherit SSH_AUTH_SOCK and SSH_AGENT_PID from it. -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
