I have 5 IMAP accounts. The main INBOX is fastmail.fm. The others are incoming-folders=PostaccessLite {mail.postaccesslite.com/user=xxx@postaccesslite.com}INBOX, PostaccessLite-fredlwm {mail.postaccesslite.com/user=yyy@postaccesslite.com}INBOX, Bluebottle {mail.bluebottle.com/user=xxx@bluebottle.com}INBOX, MyRealBox {imap.myrealbox.com/ssl/user=xxx}INBOX When I switch from one of the PostAcessLite accounts to another, no matter if they're empty, have a single message, or more, Pine stays at the "Closing folder foo" for a very long time, like 30s to 1 minute, and then opens the one I select. I have all latest packages on XP Professional SP1 with all updates, and use NTFS. Since PostacessLite doesn't seem to allow new users to create accounts, I'm willing to let Eduardo log in mines. Or let me know how to "debug" it. Pine's -d imap4 doesn't show anything different. -- How to contact me - http://www.pervalidus.net/contact.html -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ ^ permalink raw reply [flat|nested] 15+ messages in thread

If you can show me the part where you switch mailboxes, it would be great. At the top of my head, among things you may want to look into are the rsh-timeout, and ssh-timeout. Make sure both of them are equal to 0. Let me know how that goes. -- Eduardo http://www.math.washington.edu/~chappa/pine/ -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ ^ permalink raw reply [flat|nested] 15+ messages in thread

I don't have any other firewalls enabled. fhandler_socket::close() tries to circumvent problems with unexpected data loss which can occur, if an application exits without having waited for the closesocket() call being successful. The problem with the latter is, that there's no way to find out. Therefore Cygwin lingers on closesocket(), even with non-blocking sockets. I don't know if that helps but you could try to build a Cygwin DLL which only lingers if shutdown hasn't been called. I tried it with ssh and it seems at least not to disturb ssh operation.

Patch below. It behaves the same. I applied your patch and compiled latest CVS. 6735077 Nov 12 17:02 cygwin1.dll And in gdb I still see #2 0x00000005 in ?? () #3 0x00000004 in ?? () #4 0x00000001 in ?? () #5 0x00e3ffd0 in ?? () #6 0x81f2eda8 in ?? () #7 0xffffffff in ?? () Anyway, since disabling filtering 'TCP NULL' worked for 'a logout' I'll see what I can do in the modem configuration to make the Pine delays go away.
