Mintty/tmux hangs for 1 minute on startup - seems to be a forking issue
I first reported this problem to the Mintty project at GitHub. With their help, I was able to debug the issue to the call to forkpty. I installed tmux and found it also hangs the exact same way. My guess is any process which makes this fork call will hang in a similar way. Rather than copy/paste the thread, I'd rather just refer you to there : https://github.com/mintty/mintty/issues/960 I will also direct link to the strace log I made which includes my comment showing where the hang happens: https://github.com/mintty/mintty/files/4136651/mintty.strace.log (Line 718 is the hanging point.) Also Windows 10's analyze wait chain function in TaskManager shows the process waiting for Network I/O, but we see no evidence of network activity. https://i.imgur.com/Uiw9laH.png I haven't seen any other windows applications hang thusly, so I'm at a loss for what I've done to my windows system to have caused this. Otherwise, I'd expect others to share my pain. Any ideas? cygcheck.out Description: Binary data -- 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
[PATCH v2] Cygwin: console: Revise color setting codes in legacy console mode.
- With this patch, foreground color and background color are allowed
to be set simultaneously by 24 bit color escape sequence such as
ESC[38;2;0;0;255;48;2;128;128;0m in legacy console mode.

Format a USB drive as NTFS, copy the Cygwin directory tree verbatim onto that, then copy the Cygwin directory tree verbatim onto the destination system.

>>> Cygwin is totally portable!

I have been using this approach for years. To a new naked Windows box, if you can "mount" it over the network, e.g., map a drive letter to it, then you can use cygwin tools from an existing box with cygwin, to copy cygwin to the new. I usually use cygwin tar, but I think 'cp -a' will work. I think in the past, I have used robocopy. The key is the links and symlinks: normal Windows tools won't get them right. For upgrades, once cygwin is on both boxes, I always use tar. I've got this down to pretty much routine. I do it once or twice a year. I upgrade cygwin on one box, vet it for a few days, then upgrade several others. I untar into an empty dir, then use native cmd.exe 'move' to swap the dirs. Be sure to use 64-bit cygwin. The 32-bit used to work, but now and then I would have to fuss with "rebase". I have never had that problem with the 64-bit. --- Karl Botts, kdbo...@usa.net -- 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

[newlib-cygwin] Cygwin: fstat_helper: always use handle in call to get_file_attribute

commit 76dca77f049271e2529c25de8a396e65dbce615d

Date: Thu Jan 30 10:08:21 2020 -0500
Cygwin: fstat_helper: always use handle in call to get_file_attribute
When fhandler_base::fstat_helper is called, the handle h returned by
get_stat_handle() should be pc.handle() and should be safe to use for
getting the file information. Previously, the call to
get_file_attribute() for FIFOs set the first argument to NULL instead
of h, thereby forcing the file to be opened for fetching the security
descriptor in get_file_sd().

This lower-casing PFILE_ALL_INFORMATION looks like a typo. Other than
that the patch looks ok.

How do you copy it? Which archive container do you use? I have tried it with: /: cat zip.bat cd C:\ \7z\7za a -tzip -xr!cygwin64/home/* -xr!cygwin64/var/log/* tmp\cygwin64.zip cygwin64 But in resulting cygwin64.zip the directories /cygdrive /proc /usr/bin and /usr/lib are missing, because they are mount points.
