I'm not sure how to try out a test release without risking destabilizing my system, but I re-cloned and rebuilt the master branch and installed just the cygwin1.dll and all looks good to me so far. No issues with any of my script pipes or fifos and I am getting full gigabit speeds with rsync.
I too have been following all the pipe rework on Cygwin-developers and want to express my appreciation for Takashi, Ken and Corinna for tackling this. You folks have made Cygwin so much more usable for a lot of applications! -- Chris On Fri Sep 17 2021, at 1:33 PM, Ken Brown via Cygwin-announce via Cygwin <cygwin@cygwin.com> wrote: > The following packages have been uploaded to the Cygwin distribution as test > releases: > > * cygwin-3.3.0-0.1.9814cfd8f693 > * cygwin-devel-3.3.0-0.1.9814cfd8f693 > * cygwin-doc-3.3.0-0.1.9814cfd8f693 > > This release comes with an overhaul of the internal pipe code.
