tmux 2.x performance regression when switching windows
Hello,
I noticed moving between tmux windows became much slower since 2.0.x when
running some applications in the windows. The problems disappear if I move back
to 1.9. To reproduce:
- Cygwin: CYGWIN_NT-6.1-WOW PMD 2.0.2(0.287/5/3) 2015-05-08 17:03 i686 Cygwin,
Win7 64 bits.
- Start tmux and create two windows.
- In one of the windows, execute the following Go program (natively compiled,
Go 1.4.2 64-bits):
"""
package main
import (
"fmt"
"time"
)
func main() {
for i := 0; ; i++ {
fmt.Println(i)
time.Sleep(500*time.Millisecond)
}
}
"""
- Try switching between windows
KO => it eventually succeeds but lags a lot. With 1.9, the switch is immediate.

Re: File permissions different inside and outside cygwin root
(Sorry I cannot reply directly to the previous email I just subscribed to the list, I am quoting from the list archive) >> (from the archive - permissions inside and outside of /cygwin get messed up) I think this is *THE* cause of my problems. My question is how do I turn this of 100% totally - and completely? How it is effecting me: In my case, I *OFTEN* edit source code using ‘emacs-w32’ under cygwin. and often refer to files via a filename like this /cygdrive/c/some/path/foo.c Sadly what happens in the end is, the ACL gets set to the point where I cannot edit source files. Another common example is this: Step 1: On Linux - create a “tar.gz” of a source directory. tar cfz foo.tar.gz somedirectory (In my case, it is an open source package that *must* build under both cygwin and linux) I need to move the code back and forth - to make sure my changes don’t break things Step 2: Pull that tar file over to Cygwin (I use cygwin64) Step 3: Unpack the tar.gz file using CYGWIN tar xfz foo.bar.tz Step 4: I specifically use “emacs-w32” - to edit the source code. It seems that *randomly* the ACL gets totally bunkered Maybe there is a method to this madness, but I can’t figure out the exact sequence I am *NOT* building or doing this under any Cygwin mount I should not need to, and I should not be required to I specifically use: /cygdrive/c/some/path/ **NOTE** This does not *require* the ‘tar-copy’ method Using CYGWIN - I “git clone” some repository and edit the files in the standard way It seems to be more predominant when I copy via TAR across systems. Result: I can no longer edit my source code. I would end up having to “right click” permissions and fix things using windows tools It seems the ACLs are totally messed up Bottom line, my expected behavior I should be able to use a simple editor - i.e.: Emacs-w32 I should be able to edit a source code file When I save the source code file - the permissions *before* and *after* should be identical They are not, permissions are totally messed up. What ever I am seeing, it is fundamentally broken. -Duane. -- 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
Help on patching xdvipdfmx in texlive
Hi, I can't use CID-keyed fonts (SourceHanSans) with xelatex but find a solution. (http://tug.org/pipermail/xetex/2014-July/025387.html) The solution need to patch xdvipdfmx and the patch could be found in ``` https://gist.github.com/jjgod/c1194a9b371848aaa746 ``` There is not patched xdvipdfmx binary file for cygwin. How can I get source and apply patches? Or could Ken help to patch it?

The most ineffective I should also say. So I will repeat the usual disclaimer: The package you are using (what ever it is, I have no clue) is likely using a cygwin utility called rsync. It seems whoever provide it is bundling and old version of the cygwin kernel. Our answer is always : update to the last version, this problem was solved around one year ago... Solution for you : contact who distribute it and report the problem, we can do nothing for you. Additional suggestion: before writing on a mailing list it is worth to look for previous message with the same problem. http://lmgtfy.com/?q=FAST_CWD Regards Marco -- 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

That's okay. I would wait. Thanks!
