I'm in the process of reading the git documentation to figure out how to do that, but I wouldn't object if someone would save me some time by giving me the appropriate git commands. I've had a quick look at how the GNOME folks use their release branches: they are tagged in master and then only some version bumping and a few quickfixes. There are no odd numbered releases, so I assume they start the disruptive changes right after a release, tag the unstable version in master with an odd number and then work out the kinks until the new release is done. So, you can indeed start on the 2.32 branch and then bisect down to the 2.30 tag. Don't bother with the run-up between 2.31 and 2.32, just bisect it whole, the bisect sequence will be just one build longer if at all. git checkout glib-2-32 git bisect start bad git bisect good 2.30.3 If any of the intermediate versions doesn't build, say git bisect skip with the offending commit still checked out. Thanks, Achim. That helps a lot. The only thing I might have to change is the starting point for the bisection, since the tag 2.30.3 represents a fairly recent commit.

I reverted all GNOME components to the versions in that CTM snapshot, and then I upgraded them one at a time until the emacs problem appeared. This happened when I upgraded libglib2.0_0 from 2.30.2-1 to 2.32.2-1, so I downgraded it again. I also had to keep the following old versions: libgtk2.0_0-2.24.10-1 libgdk_pixbuf2.0_0-2.24.1-1 libpango1.0_0-1.29.4-2 When I tried to upgrade any of those, emacs would immediately exit with error 127.

I found an XP system that hadn't been upgraded in a few weeks, and I upgraded libglib2.0_0 but nothing else. This was enough to trigger the problem. I can reliably reproduce it as follows: 1. Start the X server (on an XP system) via the Start Menu shortcut. 2. Install emacs-X11-23.4-2, and start emacs under X. 3. Type 'C-x b RET' to switch to the *scratch* buffer. 4. Press and hold one key. It echoes once, but the repeated key strokes don't get echoed until you release the key. Fortunately for emacs users, the problem doesn't seem to occur with emacs-24. (Can anyone else confirm this?) But that doesn't help the gvim users who have reported similar problems. Yaakov, could you take a look? Maybe you could also make the previous version of libglib2.0_0 available so that users can downgrade until this gets resolved. BTW, I installed the latest Cygwin snapshot, but that didn't help.

Re: Performance problems with emacs-X11 in current cygwin (attn: glib and gvim maintainer)
Hello, Sorry, I have the same issue with emacs24 (GNU Emacs 24.0.96.1 (i686-pc-cygwin, GTK+ Version 2.24.10)). Well it seems this EMACS 24 is built with GTK2. This is the emacs package 24.0.96-2 I installed with setup.exe.

Start the X server (on an XP system) via the Start Menu shortcut. 2. Install emacs-X11-23.4-2, and start emacs under X. 3. Type 'C-x b RET' to switch to the *scratch* buffer. 4. Press and hold one key. It echoes once, but the repeated key strokes don't get echoed until you release the key. Fortunately for emacs users, the problem doesn't seem to occur with emacs-24. (Can anyone else confirm this?) But that doesn't help the gvim users who have reported similar problems. Yaakov, could you take a look? Maybe you could also make the previous version of libglib2.0_0 available so that users can downgrade until this gets resolved. BTW, I installed the latest Cygwin snapshot, but that didn't help.

Sorry, I have the same issue with emacs24 You're right, I spoke too soon. But the problem is definitely not as bad on my XP system with emacs-24. Now when I press and hold a key, it gets echoed in chunks, a few characters at a time. I don't have to wait until I release the key before seeing the characters.

Hi Ken, So I just upgraded to emacs-24 (24.0.96.1), and while it is certainly better, I wouldn't say it's fixed. Try opening a text file (I have a ~1000 line piece code). If you mouse around in the X window, and left click, the emacs cursor is sluggish to move. In fact it appears the more mouse movement between clicks, the more sluggish emacs is to respond. Something not consuming PointerMotionMask events, perhaps? best regards, stephen (edit to add: the gmane web interface has just given me moron as my captcha, that is awesome!) -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

This morning, I reverted GLib2.0 to a previous version and it did not solve the issue. Steps used in testing: Extracted libglib2.0_0-2.30.2-1.tar.bz2 and ran /etc/postinstall/glib2.0.sh Started XWin and attempted to edit a file via gvim (performance issue still remain) On Fri, Jun 1, 2012 at 2:39 PM, Ken Brown kbr...@cornell.edu wrote: On 6/1/2012 7:00 AM, Ken Brown wrote: I found an XP system that hadn't been upgraded in a few weeks, and I upgraded libglib2.0_0 but nothing else.
