+ * doc/fileevent.n: Accepted [Patch #465279] adding an example to
+ the fileevent manpage. Minor modifications to get a better
+ formatting. Report and patch by David N. Welton
+ <[email protected]>.
+
* The changes below fix [Bug #462317] where Expect tried to read
more than was in the buffers and then blocked in the OS call as
its pty channel driver provides no blockmodeproc through which
the OS could be notified of blocking-behaviour. Because of this
the general I/O core has to take more care than usual to
preserve the semantics of non-blocking channels.
+
+ The problem was reported by "Kevin O'Gorman"
+ <[email protected]>.
* generic/tclIO.c (Tcl_ReadRaw): Do not read from the driver if
the channel is non-blocking and the fileevent causing the read
