* Fix test failure socket-2.9: "1 {not owner}" instead of "1 {couldn't open ↵oehhar2014-04-011-9/+8

* Set return message in close if a flush error is reported (which may be an ↵oehhar2014-04-011-2/+13

| | | | | | | | | | | | * tests/io.test: which used the number of _written_ bytes or character to update the counters for the read bytes/characters. New test io-53.11. This is a backward port from the 8.5 branch.

'tell' now works for locations > 2 GB as well instead of going negative. * generic/tclIO.c (Tcl_SetChannelBufferSize): Accepted a patch by * tests/io.test: Alexandre Ferrieux <ferrieux@users.sourceforge.net> to fix the [Bug 1969953].

| | | | | | | | | | | | | | * io.test (io-53.8a): Ferrieux <ferrieux@users.sourceforge.net>, to shift EOF handling to the async part of the command if a callback is specified, should the channel be at EOF already when fcopy is called. Testcase by myself.

| | | | | | | | | | | | | | | | | | | | | | TclCopyChannel): New macro, and the places using it. This change allows for bi-directional fcopy on channels. Thanks to Alexandre Ferrieux <ferrieux@users.sourceforge.net> for the patch. * tests/io.test (io-53.9): Made test cleanup robust against the possibility of slow process shutdown on Windows. Backported from Kevin Kenny's change to the same test on the 8.5 and head branches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commentary to a piece of code which relies on BUFFER_PADDING to create enough space at the beginning of each buffer forthe insertion of partial multi-byte data at the beginning of a buffer. To explain why this code is ok, and as precaution if someone twiddled the BUFFER_PADDING into uselessness. * generic/tclIO.c (ReadChars): [SF Tcl Bug 1462248]. Added code temporarily suppress the use of TCL_ENCODING_END set when eof was reached while the buffer we are converting is not truly the last buffer in the queue. together with the Utf bug below it was possible to completely bollox the buffer data structures, eventually crashing Tcl. * generic/tclEncoding.c (UtfToUtfProc): Fixed problem where the function accessed memory beyond the end of the input buffer. When TCL_ENCODING_END is set and the last bytes of the buffer start a multi-byte sequence. This bug contributed to [SF Tcl Bug 1462248].
