By:
- Making the Unix socket name unique (for each Emacs instance), by
appending Emacs's PID to it.
- Changing the GDS server to listen on both Unix domain and TCP (and
not to mind if the TCP bind fails, which will happen if another GDS
instance has already bound to the TCP port number).
- Adding this unique Unix socket name to the environment (as
GDS_UNIX_SOCKET_NAME), so that Guile clients started from inside
Emacs can pick it up.
- Changing the GDS client code to look for GDS_UNIX_SOCKET_NAME in the
environment, and to connect to the Unix socket with that name
instead of over TCP.
Guile clients started outside Emacs will not find
GDS_UNIX_SOCKET_NAME and so will fall back to using TCP. This means
they will connect to whichever Emacs + GDS server instance started
first.
* emacs/gds-server.el (gds-start-server): Take both Unix socket name
and TCP port args, instead of just one (which could be either Unix
or TCP), and pass these on to `run-server'. Remove unused optional
bufname arg.
* emacs/gds.el (gds-unix-socket-name, gds-tcp-port): New variables.
(gds-socket-type-alist): Removed.
(gds-run-debug-server): Pass gds-unix-socket-name and gds-tcp-port
to gds-start-server. Add the Unix socket name to the environment.
(gds-server-socket-type): Note now obsolete.
* ice-9/gds-client.scm (connect-to-gds): Get Unix socket name from
environment, and connect to this in preference to using TCP.
* ice-9/gds-server.scm (run-server): Take both Unix socket name and
TCP port args. Listen and accept connections on both.
(Transferred from the remains of the old standalone guile-debugging
project at gna.org.)
* emacs/gds-faq.txt, emacs/gds-test.el, emacs/gds-test.sh,
emacs/gds-test.stdin, emacs/gds-tutorial.txt: New files.
When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.
* scheme-using.texi (Evaluating Scheme Code): Document use of
`C-u' prefix with evaluation commands.
* gds-scheme.el (gds-eval-region, gds-eval-expression)
(gds-eval-defun, gds-eval-last-sexp): Support `C-u' prefix,
meaning that user wants to single step through the code.
* gds-client.scm (handle-nondebug-protocol): Add support for
setting a trap on code that is about to be evaluated.
gds-show-last-stack (RET).
(scheme-mode-map): And another: C-h S.
(scheme-mode-map): And an alternative C-h G binding for
gds-apropos, as we probably should not be using C-h C-g.
(gds-run-debug-server): Use gds-server-socket-type and
gds-socket-type-alist instead of gds-server-port-or-path.

port-or-path, to support Unix domain sockets.

socket if TCP connection fails.
* gds-server.scm (run-server): Update to support listening on a
Unix domain socket.

"guile".

in traversal.
(eval-thread, gds-eval): Where expression has multiple parts,
modify output to say which part is being evaluated.
ETAGS_ARGS so that TAGS can be built using separate build
directory.
* Makefile.am (TAGS_FILES): Use this variable instead of
ETAGS_ARGS so that TAGS can be built using separate build
directory.
* debugger/breakpoints/Makefile.am (TAGS_FILES),
debugger/Makefile.am (TAGS_FILES), Makefile.am (TAGS_FILES): Use
this variable instead of ETAGS_ARGS so that TAGS can be built
using separate build directory.
* primitives/Makefile.am (TAGS_FILES), internals/Makefile.am
(TAGS_FILES), Makefile.am (TAGS_FILES): Use this variable instead
of ETAGS_ARGS so that TAGS can be built using separate build
directory.

instead of ETAGS_ARGS so that TAGS can be built using separate
build directory.
