Bug#350664: xterm: Escape sequence does not always change cursor colour

[Cameron Hutchison]

Package: xterm
Version: 208-3.1
Severity: minor

The escape sequence for changing the cursor colour does not work when
you are trying to change the cursor colour to the same colour as the
foreground text.

eg.
$ xterm -fg green -bg black
xterm$ echo -ne \E]12;red\007
xterm$ echo -ne \E]12;green\007
xterm$ echo -ne \E]12;blue\007
xterm$ echo -ne \E]12;green\007

The lines that should set the cursor to green do nothing.

The problem appears to be in charproc.c in set_cursor_gcs() where it
checks to see if the cursor colour is different from the foreground and
background colour. If so, it operates as though the cursor colour has
changed. Yet in this above case, the cursor colour has changed _to_ the
foreground colour.

Bug#334317: xterm: interpret action (in translations resource) does nothing

[Cameron Hutchison]

Package: xterm
Version: 6.8.2.dfsg.1-8
Severity: normal
Tags: patch

The interpret action available to the translations resource does not
do anything. It is meant to insert text into the input buffer as though
the user typed that text.

This used to work and broke a few months back. At that point, it looks
like the pty buffer handling changed (buffer size specified as a
resource) but the HandleInterpret function was not updated to work with
the dynamic buffering.
