Re: [Bug: 21.5-b22] Cygwin XEmacs forces line-ending conversion

================================================================ Dear Bug Team! On an up-to-date Cygwin installation with binmode Cygwin mounts, XEmacs seems to always convert DOS line ending files (no mixed endings) to Unix style line endings. Repro steps: 1) In XEmacs, edit a new file, entering several short lines of text. a) Using hexl-mode, observe that the file has DOS-style line endings. b) Save the file and kill the buffer. c) Using 'od -x <file>', observe again that the file has DOS-style line endings. 2) Load the file into XEmacs again. a) Using hexl-mode, observe that the file is no longer shown to have DOS-style line endings. *** things appear to break here b) Make some trivial change to the buffer. c) Save the file. d) Again using 'od -x', note that the file has Unix line-endings now. Off the top of my head, this sequence suggests one of two things: 1) That XEmacs has a line-ending conversion bug or 2) That XEmacs is explicitly reading the file in text mode, which causes it to see the line-endings as '\n', but writes in binary mode. This would cause the conversion as observed. -- John ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-5.1 TSISEAWS110 1.5.18(0.132/4/2) 2005-07-02 20:30 i686 unknown unknown Cygwin ./configure '--enable-mule' '--with-dragndrop' '--with-postgresql=no' '--with-x=no' '--with-site-lisp=yes' '--with-ipv6-cname=no' '--with-netinstall=no' 'CPPFLAGS=-I/usr/include/noX' XEmacs 21.5-b22 "cucumber" (+CVS-20050913) configured for `i686-pc-cygwin'.
