* Fwd: Limited clipboard buffer between X11 apps and Microsoft Windows [not found] <CAFMYRRNBpxYc42r9eSxYOC0v43jMGMySXeh3G-ARc1YT+k1LdA@mail.gmail.com> @ 2015-11-17 18:57 ` Kevin Connor Arpe 2015-11-19 12:30 ` Jon Turney 0 siblings, 1 reply; 3+ messages in thread From: Kevin Connor Arpe @ 2015-11-17 18:57 UTC (permalink / raw) To: cygwin Hello, Firstly, big shout out to all the incredible volunteers on this project. My life is infinitely more technically manageable on Microsoft Windows thanks to Cygwin. I get that Linux feeling everyday. My issue: Copying text between X11 apps and Microsoft Windows has limited clipboard buffer. My office co-worker and I were able to replicate the same issue on our machines. To replicate: 1) Run Cygwin X Server locally. 2) Run gedit remotely (using company Linux hosts) and redirect display to our local Cygwin X Server. 3) Copy some text in gedit, paste in Windows app, e.g. Notepad. We are able to find a limit (approximately 1000+ lines of text). To be very clear: We can copy small amounts to text, but not large amounts of text. My co-worker found this historical Cygwin mailing list item. It looks very similar: http://cygwin.1069669.n5.nabble.com/emacs-x11-new-clipboard-size-limitation-td104696.html When the copy/paste fails, I see the following in /var/log/xwin/XWin.0.log: [298268.591] winClipboardFlushXEvents - SelectionNotify - X*TextPropertyToTextList returned: XConverterNotFound Finally, I regularly update my Cygwin; AFAIK: my release is quite recent. $ uname -a CYGWIN_NT-6.1-WOW W01BBSAV 2.3.0(0.291/5/3) 2015-11-09 10:22 i686 Cygwin Please let me know what I can do to provide further information & details, e.g., STC -- Simple Test Case as normally requested by Corinna.

Unfortunately, I don't think this is a recurrence of the regression in that old report. Briefly, there is a different protocol [1] for transferring clipboard contents too large to fit in a single X protocol message (approximately 262144 bytes), which is not currently implemented by the X11/Windows clipboard synchronization code. Your estimate of 1000 lines seems a little low, but in my testing this is the limit I hit.

Note there is still a limit of approx. 16MB when copying in the opposite direction (from a Windows app to an X11 app), but that is harder to fix... -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- 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 ^ permalink raw reply [flat|nested] 3+ messages in thread
