Package: xarchieR6
Version: 2.0.10-0

When using xarchie to get a ftp file, the remote machine closed the
connection.  I got a few error windows from Xarchie saying that the
connection was closed, it couldn't read from a connection, and that
it failed to get the file.  After the last window, the xterm that I
ran xarchie from scrolled with this:

Warning: Select failed; error code 9
Warning: Select failed; error code 9
Warning: Select failed; error code 9
Warning: Select failed; error code 9
Warning: Select failed; error code 9
Warning: Select failed; error code 9

It looks like the FTP connection closed unexpectedly, but xarchie
stayed in a loop trying to read from an invalid socket (no longer
connected).  It probably does not check select for certain error
values.

> Package: xarchieR6
> Version: 2.0.10-0

I've uploaded a package which has some debug statements enabled.
It's currently in Incoming/xarchieR6_debug-2.0.10-1.*
[I don't know where this debug package should be moved on the
ftp-server because there is no directory for debug versions]

Please can you do some tests with this package and mail me
the error output if the below mentioned problem occurs. Neither
D.J. Gregor (the submitter of the bug report) nor I could
reproduce it. :-(

This seems to be a known problem with xarchie. I've appended
the relevant section of the PROBLEMS file to this mail.
Unfortunately I didn't include this file in the binary packages
but I'll do so in future revisions.

-Chris

The following is the relevant part of the PROBLEMS file:
-----------------------------------------------------------------------
15. I get what seems to be an endless stream of "select failed" messages.

    These messages are coming from the heart of the X11 event dispatch
    loop. What it probably means is that one of the various file
    descriptors registered with the server for asynchronous
    notification (for Prospero or FTP) is no longer valid but hasn't
    been cleared from X's select mask. Unfortunately, the X code
    simply prints a message and loops, which means that select() will
    fail again, etc., ad nauseam.

    Please do not report this problem without the following
    information! You should add a line `#define DEBUG' before the
    `#include "debug.h"' in files ftp.c and ftp-actions.c, then
    rebuild xarchie. Include the resulting trace (from stderr) with
    your bug report.
